    FR 3 056 062 - A1 yf) A camera screen control system comprises: a capture device (1); a display device (2); a detection device (6G, 6E, 6T, 6D, 6S) which detects at least one of a state of a vehicle engine contact, of a state of an engine, of a state of a change speed, an open / closed state of a door, and a seated state of a driver; and a control device (3, 4, 5) which controls the energy consumed by the capture device and the display device on the basis of at least one type of detection output of the detection device (6G, 6E , 6T, 6D, 6S). The controller (3, 4, 5) controls at least one of the capture device and the display device to a low power consumption state when a specified time has elapsed since the detection output of the detection (6G, 6E, 6T, 6D, 6S) is changed.

    The invention relates to a camera screen control system (“CMS” for “camera monitor System” in English) which displays on a control screen images captured by cameras provided on the left and right sides. of an automobile.
    In recent years, an automobile without a mirror has been taken into account. A camera screen control system is proposed in the publication of Japanese patent application No. 2015-226233 (JP 2015-226233 A). In place of the left and right exterior mirrors of an automobile, the camera-control screen system is configured by comprising: left and right lateral cameras which respectively capture a rear region of the automobile from left lateral regions and right of it; and a control screen which is arranged in a position where an occupant in a vehicle interior can visually identify the control screen and which displays images captured by the side cameras. Individual occupants who not only include a driver but also include occupants in a passenger seat and a rear seat can visually identify the image displayed on the control screen, and thus the camera-control screen system is extremely relevant to ensure safe movement of the automobile.
    In such a camera screen control system, when a power supply system for the automobile is stopped and a supply to the camera screen control system is stopped, the control screen stops displaying the images, and occupants can no longer control the sides and rear of the automobile. Consequently, the camera-control screen system is preferably configured so that, in a specific circumstance, the control screen is in contact with displaying the images, for example, as long as the driver is in the passenger compartment of the vehicle even a after an engine is stopped. As a variant, the camera-control screen system preferably configured so that, even when one of the engines is stopped, the control screen begins to display the images when the driver gets into the car.
    From a security point of view, it is preferable to extend a situation where the control screen displays the images as much as possible or to increase the time when the control screen displays the images. However, in such a case, the energy consumed by the control screen which displays the images becomes problematic. In particular, the energy consumption by the camera-control screen system affects the travel performance of an electric vehicle, a hybrid vehicle, or the like which has a battery as a power supply. For this reason, it is preferred that, while security is ensured by the camera-control screen system, the control screen ceases to display the images when the need is low, or the energy consumed by the camera-control system. control screen is reduced.
    The invention provides a camera screen control system which can save energy while ensuring the safety of an automobile.
    A camera screen control system according to one aspect of the invention comprises: a capture device which captures an image of an exterior of a vehicle; a display device which displays the captured image; a detection device which detects at least one of a state of a vehicle engine contact, a state of an engine, a gear change, a door, and a state of an open / closed conductive state;
    a seated state of a and a control device which controls the energy consumed by the capture device and the display device on the basis of at least one type of detection output of the detection device. The controller controls at least one of the capture device and the display device in a low power consumption state when a specified time has elapsed since the detection output of the detection device is changed.
    In the above aspect, the capture device can be constituted by left and right cameras, each of which captures an image of an area from one side to the rear of an automobile, and the display device can be constituted by left and right control screens which respectively display left and right captured images.
    In the above aspect, the control device can control a display screen of the display device to darken once a specified time has elapsed since the gear change is placed in the parking position in a case where the engine is driven. In addition, in the above aspect, in a case where the engine is stopped, the control device can bring the display device into a pause state after a first specified time has elapsed since the door is closed, and can control the display device to be stopped once a second specified time which is longer than the first specified time has elapsed. Furthermore, in the above aspect, the control device can control the display device to operate normally by detecting that the driver is seated while the engine is stopped and the door is open, and can control the display device. display in a pause state by detecting that the driver is not seated. In addition, in the above aspect, the controller can control the display device to darken when the engine is stopped and a specified time has elapsed since the shift was placed in the position of parking. In the above aspect, the control device can stop the control in the low power consumption state by means of actuation by a driver.
    According to this aspect, the normal operation of the display device is maintained in a situation where it is considered that the occupant such as the driver must control the image displayed on the display device to ensure safe movement of the automobile and to ensure safety during the ascent and descent of the occupant. In the event that such a requirement that the occupant visually identifies the image displayed on the display device to ensure safe movement is low, the energy consumed by the display device and the capture device is reduced. In this way, low energy consumption of the automobile is achieved.

    Next, a description of an embodiment of the invention will be made with reference to the drawings. Figure 1 is a schematic plan view of an automobile on which a camera-control screen system of the invention is mounted. Exterior mirrors are not provided on the left and right sides on an exterior of a vehicle body of a CAR automobile. Left and right side cameras IL, IR are arranged respectively in light housings of the left and right clearance lights SML. The left lateral camera IL captures an image from a left lateral zone to a rear left zone AL of the automobile CAR. The right side IR camera captures an image from a right side area to a rear right rear area of the CAR automobile. Hereinafter, the two lateral cameras IL, IR are collectively called camera 1.
    Figure 2 is a schematic front view of a front area of a DS driver's seat in a passenger compartment of the motor vehicle CAR, that is to say a dashboard DB in the case present. In the drawing, three control screens are aligned in a horizontal direction. The one in the center is a central control screen 2C, and a left side control screen 2L and a right side control screen 2R are respectively arranged at the left and right ends of the dashboard DB, i.e. in interior areas front left and right uprights. The central control screen 2C is configured here as a display screen for a NAV navigation system. The left side control screen 2L displays the image captured by the left side camera IL, and the right side control screen 2R displays the image captured by the right side camera IR. Hereinafter, the two lateral control screens 2L, 2R are collectively designated control screen 2.
    The left and right side cameras IL, IR and the left and right side control screens 2L, 2R described above are electrically connected to a body of the camera screen control system 10. Via the command by this camera screen control system body 10, a display of the captured images is controlled, and an energy saving command of the energy consumed, which will be described below, is executed.
    Figure 3 is a block diagram of a configuration of the camera screen control system in the embodiment. The camera screen control body 10 is provided with: an electronic camera control unit 3 which controls the left and right side cameras IL, IR; and an electronic control screen control unit 4 which controls the left and right side control screens 2L, 2R. The electronic camera control unit 3 performs signal processing of the signals captured by the left and right side cameras IL, IR and delivers the captured signals as image signals to the electronic control screen control unit 4 The electronic monitor screen control unit 4 performs signal processing of the image signals to make the image signals of a type which conforms to the display on the monitor screen, and outputs the image signals to the left and right side control screens 2L, 2R.
    As an electronic control unit which performs a main control of the camera screen control system, an electronic control unit body 5 which is mounted on the automobile is used in the camera screen control body 10. This electronic control unit body 5 is configured to control the electronic camera control unit 3 and the electronic monitor screen control unit 4 as will be described below and control operations of the left side cameras and right IL, IR and left and right side control screens 2L, 2R via these electronic camera control unit 3 and electronic control screen control unit 4 as will be described below.
    Several sensors are connected to the electronic control unit body 5. Here, as sensors, a motor contact 6G which detects a switching state of a motor contact, a door sensor 6D which detects an open state / closed a driver's seat door, a 6S door sensor which detects that a person (the driver) is seated in the DS driver's seat, a 6T gear change sensor which detects a switching state of a gear change of a transmission, and an engine sensor 6E which detects whether an engine is driven or stopped are connected to the body of the electronic control unit 5. In addition, a timer 7 is installed in the unit body electronic control 5, and timer 7 measures a time since a specific detection signal is entered. Next, a description will be given of a detection operation of each of these sensors.
    6G motor contact
    The 6G motor contact detects a switching position of the 6G motor contact and detects the following states. “OFF”: the 6G motor contact detects a state where the motor contact is OFF. "ACCESSORY": the 6G motor contact detects a state where the motor contact is switched to an accessory. While electrical equipment such as a radio and navigation system are on, the engine is in a stopped state. "IGNITION": the 6G motor contact detects a state where the motor contact is switched to IGNITION. Normally, the engine is in a driven state; however, there is a case where the engine is in a state before being started.
    6D door sensor
    The door sensor 6D detects an opening / closing of the driver's seat door and detects the following states. "OPEN": a state where the driver's seat door is open, and "CLOSED": a state where the driver's seat door is closed.
    6S seat sensor
    The seat sensor 6S consists of a pressure sensitive sensor which is provided in the driver's seat, and detects the following state. "Present": the seat sensor 6S detects a state where the person is seated in the driver's seat. "Absent": the 6S seat sensor detects a state where the person is not seated in the driver's seat.
    6T speed change sensor
    The 6T shift sensor detects the following states of a shift position in the automobile transmission. "P": the 6T gearshift sensor detects a P (parking) state of the gearshift lever.
    "D. R ”: the 6T speed change sensor detects a D state (forward travel) or an R state (reverse) of the shift lever position. "N": the 6T shift sensor detects an N (neutral) state of the shift lever position.
    6E engine sensor
    The engine sensor 6E detects the following stages of a speed of rotation of an engine output shaft. "Motor drive": the motor sensor 6E detects a state in which the motor is driven. "Engine stop": the engine sensor βΕ detects a state where the engine is stopped.
    On the basis of the detection signal which is detected by each of the above sensors, the body electronic control unit 5 controls the energy consumed by itself (the body of electronic control unit 5) , controls the energy consumed by the electronic camera control unit 3 and the electronic control screen control unit 4, and further controls the energy consumed by the left and right side cameras IL, IR and the left and right control screens 2L, 2R. As the control modes of the energy consumed by the electronic control unit body 5, the electronic camera control unit 3, and the electronic control screen control unit 4, the following control modes are allowed.
    Body electronic control unit 5 "Normal": all the electrical components mounted on the automobile, that is to say each of the electrical components which are required for the movement of the automobile are controlled. A control of the camera-monitor system is included here, and camera 1, monitor 2, electronic control unit of camera 3, and monitor electronic control unit 4 which constitute a camera system control screen control are controlled. "ECONOMY" while "ECONOMY" is stopped.
    a command linked to the camera-control screen system is ensured, the rest of the command is stopped if necessary or becomes a redundancy command. The energy consumed can be reduced by stopping or the redundancy command.
    Electronic camera control unit 3 "Normal": when the signal captured by camera is entered, the signal captured signal processing to generate the specific, and this image signal is delivered to the electronic control unit d 'control screen. "ECONOMY": signal processing of the captured signal is stopped. Alternatively, signal processing is performed; however, redundancy signal processing is performed compared to "normal" time. The image signal is output as an image signal, one view of which is abandoned. The energy consumed is the energy consumed low.
    Electronic control screen control unit 4 "Normal": the image signal from the electronic camera control unit 3 is subjected to signal processing to generate a display signal, and the signal d the display is delivered to the control screen 2.
    image signal signal processing
    Alternatively, signal processing is performed; however, redundancy signal processing is performed compared to "normal" time. The image signal is output as a display signal, one view of which is abandoned. The energy consumed is the energy consumed low.
    CAMERA 1 (side cameras IL, IR) is subjected to the image signal "ON": A power supply to the camera is on, the captured signal is delivered to the electronic camera control unit by an element capture installed in the camera. "OFF": The camera's power is off, and a capture operation is stopped. The energy consumed becomes almost zero.
    Control screen 2 (side control screens 2L, 2R) "OFF": A power supply is off, and the image is not displayed. "ON": the power is on, and the image is displayed normally. "DARK": while the image is displayed on the display screen, the intensity of a backlight is lowered, and a display brightness is lowered. "PAUSE": a power supply for the backlight and equivalent of the display screen is off, which leads to a total stop state where the image is not displayed. Unlike OFF, the control screen 2 can instantly be brought back to an image display state.
    It should be noted that, although this is not shown, an indicator which consists of a light-emitting diode or equivalent can be fixed on the control screen 2. For example, when the indicator is lit for "PAUSE", it indicates that the control screen in a low energy consumption state is in a "PAUSE" state. In this way, the state of "PAUSE" can be distinguished from a fault or equivalent on the control screen. A decreasing order of an amount of energy consumed by this control screen is ON> dimmed> pause> OFF.
    As energy saving control modes, such as a reduction or elimination of the energy consumed, in the camera-control screen system which is configured as described so far, control modes in modes M1 to M14 can be implemented in this embodiment. FIG. 4 is a table of the modes M1 to M14, and these modes Ml to M14 will be described sequentially with reference to this FIG. 4 and to the flowcharts in FIGS. 5 to 8, which will be presented below.
    Modes Ml, M2, M3
    In a sequence F1 in FIG. 5 during the motor drive, a "normal command" is executed as an initial configuration fault (SU). In "normal control", the electronic camera control unit 3, the electronic control screen control unit 4, and the electronic control unit body 5 are controlled in "normal", and the camera 1 and the control screen 2 are simultaneously controlled in "ON" mode. Then, the electronic control unit body 5 detects a state of the motor contact 6G. If the electronic control unit body 5 detects that the motor contact 6G is placed on "IGNITION" (S12), the electronic control unit body 5 then detects an engine state by means of the motor sensor 6E (S13 ). In step S12, if the state of the motor contact 6G is other than “IGNITION”, that is to say if “ACCESSORY” or “STOP”, sequences F2, F3, which will be described below. If the electronic control unit body 5 detects the "engine stop" in step S13, the process also proceeds to the sequences F2, F3.
    In step S13, if the "driven motor" is detected, the electronic control unit body 5 further detects a state of the speed change sensor 6T (S14). If the 6T shift sensor is “D. R ”, the current state, that is to say the state of the“ normal command ”is maintained. This corresponds to the state mode of the process going on.
    Ml and is a state where the automobile is moving. The camera 1 performs a normal capture operation, and the electronic camera control unit 3 delivers the captured signal as an image signal to the electronic control screen control unit 4. Based on the signal image, the electronic control screen control unit 4 sends the display signal to the control screen 2, and a captured side or rear image of a host vehicle is displayed on the control screen 2 with a specified brightness. This command in the Ml mode is executed independently of an opening / closing of the door and of the presence / absence of the person on the seat.
    If the speed change sensor 6T is "P" in step S14, the electronic control unit body 5 determines a state of the door sensor 6D (S15). If it is detected that the door sensor 6D is "closed", the electronic control unit body 5 measures a time since the speed change sensor 6T is detected as "P", that is to say tell the time since the speed change sensor 6T is switched to "P" using the timer 7. On the other hand, if it is detected that the door sensor 6D is "open", the unit body electronic control 5 detects a state of the seat sensor 6T. If it is detected that the seat sensor 6T is "present", the electronic control unit body 5 also measures the time since the speed change sensor 6T is detected as "P" using the timer 7 (S17). Until a specified time, i.e. seven minutes in this case, elapses in timer 7, the mode M1, which is controlled in step S14, is maintained.
    Once seven timer 7 since speed 6T is switched to minutes elapse in the "P" change sensor, the electronic camera control unit 3, the electronic screen control unit 4, and the electronic control unit body 5 are kept "normal", and the control screen 2 is controlled "to be darkened" while camera 1 is kept "ON" (S18). This corresponds to a command in M2 mode. A probability that the driver causes a displacement of the automobile is currently low, and a possibility of using the control screen 2 is thus low. However, the image is displayed minimally on the control screen 2, so as to ensure security.
    In step S16, also, if the seat sensor 6T is "absent", the control screen 2 is controlled to be "darkened" while the electronic camera control unit 3, the unit control panel 4 electronic control unit, and the electronic control unit body 5 are held at "normal", and the camera 1 is held at "ON" (S18). The mode is then switched to M3 mode. From the above, since it is estimated that the driver is temporarily getting out of the car, the control screen 2 displays the image with a brightness such that the image can be minimally controlled . In this way, the driver outside the vehicle can control the image on the control screen 2.
    As just described, when the engine is driven, the normal control state in Ml mode is maintained in principle, and the side or rear image of the host vehicle, which is captured by the camera 1 , is displayed on the control screen 2 in a bright state. In this way, security is ensured by the camera-control screen system. Furthermore, if it is determined that we are currently in a situation where the possibility of the driver using the camera screen control system is low, the command in the M2 or M3 mode is executed. The control screen 2 is then "darkened" to display the image in minimum brightness. In this way, the energy consumed is reduced while security is ensured by the camera screen control system.
    It should be noted that, although this is not shown in FIG. 4, a situation where the engine contact 6G detects “IGNITION” but the engine sensor 6E detects the “engine stop” corresponds to a state before the engine contact 6G is switched to a starter to start the engine or a case where the engine is unintentionally stopped. In this case, since a probability of driving is high, the state of "normal control" is preferably maintained. As a variant, the control in the modes M4, M5 is executed, and the control in the modes M4, M5 is similar to a case where the motor contact 6G is “ACCESSORY” as shown in a sequence F2 below.
    Here, although not shown, a sensor which detects a state of an automobile handbrake can be connected to the body of the electronic control unit 5, and this handbrake sensor can be combined with the 6T speed change sensor. A command similar to the command which is executed when the speed change sensor 6T detects "P" can be executed by combining a detection "N" of the speed change sensor 6T and a detection "ON" of the handbrake.
    Modes M4, M5
    If the motor contact 6G is "ACCESSORY" in step S12 of the sequence F1 described above during ACCESSORY, or if the "engine stop" in step S13, the sequence F2 in FIG. 6 is executed. This indicates a time when the 6G engine contact is detected as "ACCESSORY", the engine is stopped, and the automobile does not move. Thus, the electronic control unit body 5 is controlled by "ECONOMY" (S21). With this command to "ECONOMY", while the electronic control body 5 provides the camera-control screen control, the energy consumption by the command linked to the movement of the automobile can be reduced.
    unit of the system Here, this command to "ECONOMY" by the body of electronic control unit 5 is called "quasi-normal command". More specifically, in this "quasi-normal control", the electronic control unit body 5 is in "ECONOMY", the electronic camera control unit 3 and the electronic control screen control unit 4 are "Normal", and camera 1 and control screen 2 are both on "ON".
    In addition, during "ACCESSORY", the 6T speed change sensor is normally in "P" or "N". Thus, the 6T speed change sensor should not be particularly detected. However, it is assumed here that "P" is detected.
    Then, the seat sensor 6T is detected (S22). If the door sensor 6S detects "present", the "quasi-normal control" is maintained. If the door sensor 6S detects "absent" in step S22, the door sensor 6D detects "closed" or "open" (S23). If the door sensor 6D detects "open", the "quasi-normal control" is maintained. The "quasi-abnormal command" which includes these steps corresponds to the M4 mode. In these situations, the driver waits while seated, or gets back into the car after getting off the first time. Thus, it is considered that a possibility that the driver starts driving again is high.
    On the other hand, if the door sensor 6D detects "closed" in step S23, the time since the door is closed is measured by the timer 7 (S24). Until a specified time, for example, seven minutes, elapses, "near normal control", that is, M4 mode, is maintained. When seven minutes have elapsed, the control screen 2 is commanded to "PAUSE" (S25).
    This corresponds to the M5 mode, and it is therefore considered that the possibility that the driver starts to drive again is low. The display screen of the control screen 2 which is controlled on "PAUSE" is brought into a state of total stop. However, at a time when the driver opens the door or sits on the seat, the control screen 2 is returned to the display state and can thus respond to the camera-control screen system. In addition, due to the "PAUSE", the energy consumed by the control screen 2 is reduced.
    Modes M6 to M9
    If the motor contact 6G is detected as being “OFF” in step S12 of the sequence F2 in FIG. 6 during the door “open”, a sequence F3 in FIG. 7 is executed. In this case, the engine is normally stopped, and the gear change is normally in "P" or "N". Thus, the engine sensor 6E and the speed change sensor 6T are not detected. In addition, the fact that energy is not delivered to the electronic control unit body 5 when the motor contact 6G is "OFF" is normally configured. However, in this embodiment, similar to step S21 of the sequence F2, the electronic control unit body 5 executes the "quasi-normal command", so as to control itself at "ECONOMY" (S31). In this way, the control of the camera-control screen system is ensured in a minimal manner.
    In this sequence F3, if the door sensor 6D detects "closed" (S32), a sequence F4, which will be described below, is executed. If the door sensor 6D detects "open", the timer 7 measures a specific period which is two minutes here (S33). Until two minutes have passed, the seat sensor 6T performs the detection (S34). "Present" detected by the door sensor 6S means that the driver is getting into the car, and "absent" means that the driver is getting out of the car. If "present", the "quasi-normal command" is maintained. This corresponds to M6 mode, the control screen 2 is on "ON" and displays the image in strong light. Even if the 6G engine contact is in the “OFF” position, the driver is seated. Thus, in order to ensure safety when getting out of the car later, the control screen 2 can be controlled.
    If "absent" in step S34, the control screen 2 is "darkened" and is controlled for energy saving (S35). This corresponds to M7 mode, and the energy of the control screen 2 is saved. The driver is considered to be getting out of the car at that time, or it is a moment immediately after the driver gets out of the car. Thus, the control screen 2 continues to display the image. However, it is considered that there is no problem even when the brightness of the display screen is lowered.
    If two minutes have passed since the door sensor 6D detects "open" in step S33, the control screen 2 is controlled on "PAUSE" independently of the detection by the seat sensor 6T, c that is to say independently of "present" or "absent", and the screen of the control screen 2 is brought into the state of total shutdown (536). This corresponds to M8 mode, and the energy of the control screen 2 is saved. Note that "-" in the table of figure 4 represents the fact that the component with the symbol does not influence the state. When two minutes pass from "open", the driver is considered to have already gotten out of the car or a high possibility that the seated driver is not driving the car. Thus, it is preferred to reduce the energy consumption by the control screen 2 as much as possible.
    Furthermore, the timer 7 continues the measurement (537). If seven minutes have passed since the door sensor 6D detects "open", the electronic camera control unit 3 and the electronic control screen control unit 4 are both set to "ECONOMY" ( S38) while the command “PAUSE” of the control screen 2 in step S36 is maintained. This corresponds to mode M9, and the energy of the control screen 2, the electronic camera control unit 3, and the control screen 4 is saved. When seven minutes elapse from "open", the driver is considered to be almost certainly out of the car, or the driver is not driving the car. Thus, the energy of the camera-control screen system comprising the control screen 2 is controlled to the minimum.
    Modes M10 to M14
    If the electronic control unit body 5 is controlled to "ECONOMY" in step S31 of the sequence F3 in FIG. 7 while the door is "closed", the "quasi-normal control" is executed, and the sensor door 6D detects "closed" in the next step S32, the sequence F4 in FIG. 8 is executed. The door sensor 6S detects "present" or "absent" (S41). If "present" is detected, timer 7 measures a moment since the detection of "present" (S42). “Quasi-normal control” is maintained until two minutes have passed. This corresponds to M10 mode, and the command here is the same as that in M6 mode. Although the 6G engine contact is in the “OFF” position, the driver does not get out of the car. Thus, the control screen 2 can be controlled to continuously ensure security.
    If it is detected in step S42 that two minutes elapse from "present", the control screen 2 is "darkened" (S43). This corresponds to Mil mode. The driver is still seated, and it is not clear whether the driver is getting out of the car or starting to drive again. Consequently, the energy of the control screen 2 is saved while the control screen 2 continues to display the image.
    If seven minutes pass, the control screen 2 is placed on "pause" (S44). This corresponds to M12 mode. Although the driver is seated, the possibility that the driver will start driving again is low. Consequently, the control screen 2 stops displaying the image, and the electronic camera control unit 3 and the electronic control screen control unit 4 are both controlled in "ECONOMY" ( S45). In this way, energy is still saved.
    On the other hand, if "absent" is detected in step S41, the timer 7 measures a time since the door which is "closed" is detected (S46). "Quasi-normal control" is maintained until two minutes have passed (S43). This corresponds to the mode described above M10. The driver is considered to have gotten out of the car and to have closed the door. Therefore, the control screen 2 continues to display the image for the time.
    However, it is considered that there is no problem even when the brightness of the display screen is lowered. If it is detected in step S46 that two minutes have elapsed since the detection of "closed", the control screen 2 is controlled in "pause" (S47). This corresponds to M13 mode. Since it is considered that the driver is completely out of the car, the control screen 2 stops displaying the image. However, it is also considered that the driver may soon get back into the automobile. Thus, the control screen 2 is prepared to instantly display the image.
    Once seven minutes have elapsed, the control screen 2 is set to "OFF" (S48). This corresponds to M14 mode. It is considered that the driver is completely out of the automobile and that the driver is unlikely to get back into the automobile. Thus, there is little possibility that the control screen 2 will instantly return to the image display. In this M14 mode, the control screen 2 is set to "OFF". Thus, the energy consumed by the control screen 2 is minimized, and a high energy saving effect can be obtained. In addition, the electronic camera control unit 3 and the control screen electronics unit controlled in "ECONOMY" (S49I be further saved.
    By executing the command in modes Ml to M14 which has been described so far, control using the control screen 2 is ensured in the situation where the driver must control the side or rear area of the automobile or the situation where the driver preferably controls the side or rear area of the automobile. In addition, the energy saving by the control screen 2 or the side camera 1, the electronic camera control unit 3, control are both The energy can thus the electronic control unit control screen 4, and the electronic control unit body 5 can be produced. In this way, security is ensured by the camera-control screen system, and energy saving can be achieved.
    The configuration of the camera screen control system and the control modes in the modes M1 to M14 which have been described so far simply illustrate an example of the invention. In particular, it goes without saying that modes other than modes M1 to M14 can be applied. For example, the specified time which is measured since the detection of the situation by the sensor is not limited to the two minutes or seven minutes described in the embodiment but can be set at an appropriate time. As sensors of the camera screen control system in the invention, a sensor which detects a state locked by a door key or the fact that the driver touches a steering wheel (a steering wheel), the seated state of the driver which is analyzed by an image using a vehicle cockpit camera, and the like can be used. As regards "darkening" of the control screen according to the invention, the control screen does not always have to be controlled in a specified brightness. However, the brightness, that is to say a degree of "darkening" may differ depending on a situation. In this case, the brightness of the environment in / around the automobile can be taken into consideration.
    In this embodiment, the example in which the left and right side cameras IL, IR and the left and right side control screens 2L, 2R are simultaneously controlled in the same mode has been described. However, depending on a situation, each of the left and right side cameras and each of the left and right side control screens can be controlled in an independent state. For example, while the left side camera and the left side control screen on one side of the passenger seat can be ordered in "normal", the right side camera and the right side control screen on the side of the passenger seat driver can be ordered in "ECONOMY". Alternatively, they can be ordered in reverse.
    For example, as shown in Figure 1, the invention can also be applied to a camera screen control system which uses a rear camera IB provided in a rear section of the automobile in addition to the side cameras left and right. In this case, an image captured by the rear camera IB is displayed on the central control screen 2C, and the images captured by the left and right side control screens 2L, 2R are synthesized to display a sequential image. In this way, these control screens 2C, 2L, 2R can be configured as control screens which display a large area from the left and right sides to the rear of the CAR automobile.
    Furthermore, the invention can also be applied to an automobile which comprises left and right exterior mirrors. In particular, in an automobile in which clearance lights and indicator lights are incorporated respectively and integrally in the left and right exterior mirrors, the side cameras can be incorporated in these lights.
    Instead of being incorporated into the lights, the side cameras can be incorporated into an automobile body, such as a wing, doors, or uprights.
    The camera screen control system of the invention does not always have to be configured to constantly execute the energy saving command but can be configured to stop the energy saving command (low consumption command energy), for example when the passenger actuates a switch, and can be configured so that the control screen normally displays the image constantly.
