    Field of the invention
    The present invention relates to a method and a device for adjusting the field of view of a field of view display apparatus.
    State of the art
    According to the state of the art, a display unit of the field of view or head-up display displays an image content which can only be fully perceived in a limited field of view.
    Description and advantages of the invention
    The present invention relates to a method for adjusting the field of view of an observation field display apparatus characterized in that an adaptation step adapts the position of the light source of the apparatus of field of view display with respect to the display apparatus optics if the position information of the eye indicates that the position of the observer's eye of the field of view is outside the range of tolerance of the field of view. The invention also relates to a device for implementing such a method and a computer program for executing the method.
    When an observer, that is to say, the eyes of the observer leave the field of observation of a field of view display apparatus, the information displayed can be perceived only incompletely. In order for the information to be perceived (captured) as the observer moves, the observation field position is adapted to the position of the observer's eyes. For this adaptation, the light source of the field of view display apparatus is moved relative to the optics of this apparatus.
    By moving the light source in at least one direction of space, the field of view is simply and rapidly adapted to the position of the eyes.
    According to the invention, the method of adjusting the field of view of the field of view display apparatus comprises a step of adapting the position of the light source of the display apparatus with respect to the field of view. optics of the device if the position information of the eye (eyes) indicates that the position of an observer's eye of the field of view is beyond the tolerance range of the field of view 'observation.
    The method may for example be implemented in the form of a program or circuit or in a mixed form combining a program and a circuit, to be applied by a control apparatus.
    A light source is a light emitting component such as for example an LED diode or a laser diode or a combination of a light emitting component with an optical element in front of it forming part of the light emitting component. The optical elements forming part of a light emitting component are, for example, means that homogenize the illumination of a display surface by the light emitted by the component. Typically, the light emitting element or component comprises, for example, a collimating lens and / or a microlens array for homogenizing the illumination and a projection lens that develops a display surface with the light distributed in channels by the matrix. microlenses. The field of view display apparatus is a head-up display that develops the image information in the observer's field of view. For example, the vehicle windshield can be used to develop the image information in the field of view. You can also use a separate window. In this case, it is a combination device. The field of view is the field in which the image information provided by the display apparatus is visible in full, taking into account the construction. The optics of the field of view display apparatus generates the light provided by the light source with the image information to make this image information visible in the field of view. The windshield can be a part of the optics. The position of the eye is the pupil position of the eye. The tolerance range may be smaller than the field of view. The information of the position of the eye is the input information provided by an image capture facility. The position information of the eye can, for example, be recorded as an electrical signal.
    The position of the light source is axially adapted to the optical path of the field of view display apparatus when the position information of the eye indicates that the distance from the observer's eye is beyond the tolerance range. In other words, we adjust the distance between the light source and the optics.
    The distance between the light source and the optics can be reduced if the position information of the eye indicates that the distance of the eye exceeds a threshold. By reducing the distance, the marginal rays of the cone of light will arrive at the optics with a stronger angle and these marginal rays will thus come out of the optics with a flatter angle.
    The position of the light sources may be rotated about a vertical axis of rotation if the position information of the eye indicates that the position of the eye is laterally beyond the tolerance range. Thus, for example, the display can also be switched. The display can be connected to the optics. The position of the light source is rotated around the horizontal axis of rotation if the position of the eye is vertically beyond the tolerance range. By rotating the light source, the optical axis of the display unit of the observation field is rotated. The optic is then inclined with respect to the optical axis.
    The position of the light source is adapted if the position information of the eye indicates that this position is deviated from the central area of the field of view. The central area is the center or the observation center. The position of the light source will be adapted all the more strongly as the position of the eye will be removed from the central area.
    The position of the light source can adapt step-by-step, which reduces the means to implement for adaptation. The position of the light source can, for example, adapt in predefined time intervals. Similarly, the position of the light source can be changed according to a predefined step when the tolerance range is exceeded. The invention also relates to a device for applying the steps of the method, for controlling or transposing the method. The device can respond quickly and effectively to the problem.
    The device according to the invention is an electrical apparatus which processes the signals of the sensors and generates control signals and / or data signals as a function of this processing. The device comprises an interface in the form of a circuit and / or a program. In the case of an embodiment in the form of a circuit, the interfaces are for example part of an ASIC system (dedicated circuit) which comprises the various functions of the device. But, it is also possible to have clean interfaces, with integrated circuits or which are at least partially formed with discrete components. In the case of a realization in the form of a program, the interfaces are existing program modules for example in the mircrocontroller alongside other program modules. The field of view display apparatus according to the invention comprises an information field setting device as indicated above.
    According to another characteristic, the subject of the invention is a computer program product or more simply a computer program with a program code recorded on a machine-readable memory medium such as a semiconductor memory, a computer program product or a computer program. hard disk or optical memory to execute, apply, and control the process steps, according to the above developments, especially when the program product or program is run on a computer or a computer.

    Description and embodiments
    Figure 1 shows a vehicle 100 having a field of view display apparatus 102 according to an exemplary embodiment. The field of view display apparatus 102 uses an image generator 104 and an optics 106 to project image information 108 onto a virtual screen 110 which appears to float for the observer 112, at a distance of projection of the windshield 114 of the vehicle 100. The field of view display apparatus 102 is a head-up display 102. The image generator 104 is still referred to as the PGU image generator unit. The windshield 114 is here at least partially part of the optics 106.
    FIG. 1 shows the schematic structure of a head-up display 102. The head-up display 102 forms the image plane of the image generator unit 104 by means of the head-up optics 106, in the form of a head-up display. a virtual image in front of the vehicle. The driver 112 thus perceives an enlarged image generated by the image generator unit 104. This image is superimposed on the driving scene and is at a defined distance from the windshield 114 on the virtual screen 110. use LCD modules as image generating elements of the image generator unit 104. The virtual image shown is an enlarged image of the display, generated by the image generator unit 104. This is why, optics 106 must have some magnification. The necessary magnification increases with the distance of the virtual screen 110 because the image provided by the image generator unit 104 will be further magnified to be perceived at a greater distance in the field of view of the driver 112. The head-up display 102 may generate a screen 110 at a distance of about 15 m.
    In the reverse light field, the enlargement of the optics 106 focuses the solar beam onto the image generator 104 for incident solar light. The image generator 104 may heat up and reach a temperature that destroys it. The temperature rise in systems using LCD liquid crystals is critical because the module can be permanently damaged as soon as it reaches a temperature of 100 ° C. In the case of a temperature of about 95 ° C, there is a delamination of the polar filter; at 105 ° C, an isotropic liquid crystal develops and at 125 ° C the damage of the liquid crystals is definitive.
    FIG. 2 shows a vehicle 100 equipped with a stereoscopic self-observation field display device 102 corresponding to an exemplary embodiment. The optical field display apparatus 102 substantially corresponds to the field of view display apparatus of Fig. 1. The image generator 104 provides a straight image information 200 for the eye right of the observer 112 and left image information 202 for the left eye of the observer 112. The shift between the right image information 200 and the left image information 202 allows a spatial representation for the observer 112.
    The figure shows the principle operation of an auto-stereoscopic head-up display 102. The HUD display system, stereoscopic auto 102, uses partial images 200, 202 distinct for the left eye and the right eye, to generate a relief effect as in the cinema. The image generator unit 104 for this purpose generates the two partial images 200, 202. The optics 106 transmits the light of the partial images 200, 202 to each eye in a smaller eyepiece box.
    Fig. 3 shows a block diagram of a device 300 for adjusting the observation range 302 of an observation field display apparatus 102 according to an exemplary embodiment. The observation range 302 can be considered as an eye box. The field of view display apparatus 102 essentially corresponds to that shown in FIGS. 1 and 2; it is intended to be installed in a vehicle.
    The device 300 comprises a calculation unit 304 and a training unit 306. The calculation unit 304 is connected to a gripping system 308 to enter the position 310 of the eyes of the observer 112; it reads the position information 312 from the eye position 310 of the input system 308. The computing unit 304 using the eye position information 312 calculates the position information 314 of the light source. The position information 314 of the light source represents the position 316 of the light source 318 adapted to the position 310 of the eyes for the field of view display apparatus 102 relative to the optics 106 of the apparatus The light source 318 is part of the image generator 104 not shown here. The position information 314 of the light source is transmitted to the drive unit 306. The drive unit 306 adjusts the position 316 of the light source according to the position information 314. By changing the position from the light source 316, the field of view 302 is modified.
    If the position of the eyes 310 leaves the tolerance range 320 in the observation field 302, the position 316 of the light source is enslaved. In an exemplary embodiment, the distance 322 of the light source is reduced with respect to the optic 106 when the observation distance 324 between the windshield 114 and the position of the eyes 310 increases. The light source 318 is moved by the drive unit 306 linearly onto the optical axis 326 of the field of view display apparatus 102.
    In the case of the example presented, the correction of the distance 324 from the eyepiece box 302 of the stereoscopic head-up display 102 for an eye is done when the observer 112 moves while moving towards or away from the -brise 114.
    Fig. 4 is a block diagram showing the generation of the range or field of view 302 of a field of view display apparatus 102, according to an exemplary embodiment. The field of view display apparatus 102 essentially corresponds to one of the field of view display apparatuses of the preceding figures. The image generator 104 comprises a light source 318 and a liquid crystal display 400 illuminated by the light source 318. From the liquid crystal display 400, the light of the light source 318 arrives in the optics 106 of the light source. the field of view display apparatus 102. The optics 106 is shown here in a very simplified manner. The optics 106 directs the light emitted by the light source 318 and focuses it in the field of view 302. The light arriving in the optics 106 diverges and the light emerging from the optic 106 converges.
    As long as an observer's eye 402 is in the field of view 302, the eye 402 will be able to capture at least a predefined part of the liquid crystal display 400. In particular, the liquid crystal display 400 can be entered entirely in field of observation 302.
    When the light leaves the field of observation 302, it diverges. If the eye 402 is closer to the optics 106 or farther away from the optics 106 than the field of view 302, the eye 402 will only partially grasp the liquid crystal display 400 and so it will only perceive partially image information.
    The field of view 302 is arranged so that the eye 402 can completely perceive the image information again, by adapting the position 316 of the light source of the image generator 104 until the light converges from new in the eye 402.
    In other words, the offset (z) is compensated for the position of the driver's eye 402 in the auto stereoscopic head-up display 102.
    The design of a head-up display 102, assumes a fixed distance between the eye 402 of the observer and the windshield. The radiation of each pixel of the display 400 of the image generator unit 104 is formed so that the pixel can be viewed from the destination eye box 302. This means that the radiation cone illuminates the eye box 302 if possible without exceeding the area. The shape of the radiation cone needed for this is usually a pyramidal shape.
    If, however, the observer approaches the windshield or away from it, the eye boxes 302 corresponding to different positions of the display 400 will no longer be superimposed correctly. As a result, in certain circumstances, the observer will no longer perceive the entire content of the image in the field of view / range of the ocular box 302. This problem may, for example, arise when the position of the seat of the driver changes.
    The solution proposed here records the position (z) of the driver's eye 402 by a head tracking system and uses this information to slave the light source 318 of the image generator unit 104 of the head-up display. 102 so that the eyepiece box 302 is adapted to the position of the driver in the direction (z).
    The light emission characteristic is corrected by the image generator unit 104 to compensate for the movement of the driver's eye 402 in the direction (z) so that the eye box 302 associated with the eye 402 located at the position (z) of the driver's eye 402. The adaptation (z) in the range in which the driver's eye 402 can perceive the image of the head-up display 102 increases; the system is thus adapted to the seating positions of the various drivers of the vehicle. The homogeneity of the image is improved in the range (z) of the observer's position.
    The dimensions in the design of the eyepiece box 302 can be reduced by the correction since the useful range (z) depends on the width of the eyepiece box and these dimensions can be smaller if increased in another way.
    By designing a thinner 302 eye box, the brightness of the image is increased.
    The offset (z) of the observer has been represented in an imaginary manner. The figure shows how the eyepiece box 302 is generated. The PGU 104 image generator unit is shown with, for example, an LCD display 400. Each pixel of the LCD display 400 radiates light that illuminates a small image. eyepiece box observation field 302 for the eye 402. The HUD optic 106 is here shown in simplified form in the form of a lens functioning as a magnifying glass. At a determined distance from the HUD optics 106, the ranges of the different pixels of the display are superimposed and show the overall image. This corresponds to the design distance for the driver's eye 402. But, if the driver departs from the optical HUD 106, that is to say the windshield or approaching, the visible ranges of different pixels deviate. As a result, the driver no longer perceives all the pixels and can no longer see the complete image.
    Without the possibility of correcting this effect, the range (z) narrows in that the driver can not move without cutting the image or other negative effects such as darkening of the image or color drift .
    In the case of the example shown, the position (z) of the eye box 302 is slaved to the eye 402 of the driver to avoid such negative effects.
    The range (z) in which the driver's eye 402 can move without the need for servocontrol depends on many factors. Among these, there is the width of the ocular box 302 but also for example, the latency time of the mechanical servoing according to the movements of the head to the left or right or the homogeneity of the image obtained for the different positions of the eye 402 in the eyepiece box 302. It is desirable to have ocular boxes 302 narrowly bounded so that the crosstalk of the light of a partial image towards the other eye will be low and the brightness of the image will be homogeneous for the different positions of the eye 402 in the eyepiece box 302. Very narrowly delimited ocular boxes 302 are obtained for example by a holographic backlight. The strictly delimited ocular boxes 302 cause the offset (z) with the spacing of the ocular boxes 302 in different display ranges to be perceived more rapidly. In particular, for such concepts, the compensation proposed above is of particular importance.
    The offset (z) of the driver's eye 402 can be continuously controlled. Similarly, the offset (z) of the eye 402 can be done in stages. Great differences in the position (z) required of the eyepiece box 302, resulting mainly from a change of conductor and its adjustment of the seat position in the vehicle. The range (z) to be treated by the system is here particularly high, whereas during driving, the range is limited to a low dynamic range. For an appropriate design of the system, it is possible to use the range (z) tolerated by the system or a control in a few steps may be sufficient.
    Since any variation in the direction (z) can be directly compensated, this reduces the accuracy requirements of entering the position (z) of the eye by the head tracking system.
    One method for determining the distance (z) is to take two camera images in different directions and thereby determine the distance by triangulation after the image processing, will have recognized the face and determined the position of the eyes on the images. Such a system has sufficient accuracy for entering the position (z).
    The direction of the driver's gaze can also be detected by a camera system recording the reflections on the pupil of the eye. In principle, such a system is suitable for determining the distance (z). The distance information (z) can be obtained in principle with different tracking systems and the distance is thus available for the proposed concepts.
    In other words, FIG. 4 is a block diagram of the generation operation of the eye box in an auto-stereoscopic head-up display 102 for one of two eyes. The display 400 of the image generator unit 104 radiates the light by each pixel to illuminate a small eye box 302 associated with the eye 402. The optics HUD 106 is represented here in a simplified manner in the form of a lens having a magnifying function. At the design distance to which the driver's eye 402 should be, the ranges of the different pixels of the display 400 are combined to display the overall image. If the driver moves however with respect to the head-up optics 106, that is to say relative to the windshield by moving closer or apart, the visible ranges of the different pixels deviate. As a result, the driver will no longer perceive all the pixels and will no longer see the complete image.
    If the LED source 318 is brought closer to the display 400, the emitted rays diverge more and arrive with a stronger angle of incidence in the optics 106. Since the refraction of the optics 106 remains the same, the point the intersection of the radiation cone shifts to the right and the outgoing, extreme radii are flatter.
    Fig. 5 is a representation of a driving scene 500 with a field of view display apparatus 502 according to an example of the invention. The driving scene 500 is represented under the driver's observation angle and corresponding to a scene on a multi-lane road with several other vehicles traveling in the same direction. The display of the field of view 502 is provided here by the field of view display apparatus described above. The movable light source allows the driver to perceive the field of view 502 even if he spreads his head from the determined position to a less precise position.
    Figure 6 shows the path of the beam 600 of a field of view display apparatus 102 according to an exemplary embodiment. The field of view display apparatus 102 essentially corresponds to the field of view display apparatus of Fig. 3. In addition, selected light beams 602 of the light source 318 are shown. passing through the field of view display apparatus 102, reaches the field of view 302. The optic 106 consists of at least one microlens array 604, a shape mirror free 606 and the windshield 114. The microlens matrix 604 is combined with a liquid crystal display 400.
    For simplicity, only the path of the beam 600 for the field of view 302 of the auto stereoscopic field of view display apparatus 102 is shown. The second field of view 302 is made by a separate light source and the same display 400 or by the same light source 318 and another display or by the same light source and a suitable display. We use the same optics 106.
    The figure shows a head-up display 102 with a microlens array 604 for the image generator unit 104. The image generator unit 104 uses an LED backlight 318 and a set of two microlens arrays. 604 to form the output radiation cone of the display 400. The display 400 itself is constituted by a free-form mirror 606 and the windshield 114.
    The LED light source 318 is installed behind the microlens array 604 for the necessary main directions of radiation to form the radiation cone on the display 400. The cone itself is formed by placing the microlens matrices 604 directly behind the LCD display 400. The dies are for example cylindrical lens matrices 604, that is to say that their refraction acts only in the horizontal direction or in the vertical direction. The microlenses 604 spread the light directly behind the display 400 thus forming the actual radiation cone. Since the dies 604 are distinct, the width of the radiation cones in the horizontal direction and that in the vertical direction are adjusted independently of one another.
    By placing a second light source, the other eye box 302 is generated for the second eye. In order to switch quickly enough between stand-alone, sequential time drives, between the two partial images, the one for the left eye and the right eye, a second LCD display with beam splitter and optics can also be used. backlit all of its own.
    Fig. 7 shows a beam path 600 of a field of view display apparatus 102 for setting the field of view 302 by the apparatus 102 according to an exemplary embodiment. The field of view display apparatus 102 essentially corresponds to the field of view display apparatus of FIG. 6. Here, there is additionally a vertical axis of rotation 700 for the light source. 318, to be able to shift the light source 318 on the side and to move the field of view 302 to the side, for example, when the eye of the observer deviates towards the side of the field of view 302. light source 318 can be tilted to the side, before the eye leaves the field of view 302.
    According to an exemplary embodiment, the light source pivots vertically about a horizontal axis. This makes it possible to vertically move the field of view 302 if the eye is likely to exit upwards or downwards from the field of view 302. The light source 318 is tilted up or down before the eye does not leave the field of observation 302.
    The figure also indicates the direction of movement 702 in the optical path of the field of view display apparatus 102, along which the light source 318 can be moved to move the field of view 302 along the path. optical. For example, the distance between the windshield 114 and the observation field 302 is reduced if the eye of the observer approaches the windshield 114. Similarly, the distance to the windshield 114 is increased. if the eye moves away from the windshield 114.
    In other words, there is shown the pivot axis 700 corresponding to the design of Figure 6 for the servo. Compensation 702 of the offset compensation (z) is also represented, by varying the distance between the LED light source 318 and the display 400.
    To enslave the eye box 302 according to the movements of the head, a head tracking system is used which detects the position of the driver's eyes using a camera system. The position of the eyes is transmitted to the image generator unit 104. This slaves the ocular boxes / field of observation 302 by slaving the light source 318 and / or the display 400 around the axis of rotation. When turning the LED light source 318 with the display 400 and the MLA units 604 around the axis of rotation 700 shown, the position of the eye box / field of view 302 moves. As a variant, only the LED light source 318 can be rotated around the corresponding axis of rotation 700.
    To compensate for the offset (z) of the observer, according to the proposal presented here, it is further possible to slave the LED light source 318 to slave the eye box 302 as a function of the distance from the driver's eye. The distance between the light source 318 and the display 400 thus varies.
    Figure 8 is a representation comparing different fields of a field of view according to an example embodiment. Three states 800, 802, 804 have been represented. Each state is represented by a line. In each line, there are five areas next to each other. There are four corner domains and one median domain. In the lines, we thus have a top left corner domain, a high right corner domain, a median domain, a low left quince domain, and a low right corner domain.
    The first state 800 represents the normal state for which the eye of the observer is in the field of view.
    The second state 802 represents an offset state in which the eye has moved away from the field of view. In this representation appear the darkened parts 806 at the edge.
    The third state 804 represents the adapted state. The eye is in the same place as in the second state, but unlike the latter the position of the light sources has been adapted so that the darkened parts at the edge 806 no longer appear.
    There is shown a simulation of the illumination of the eye box of the right eye for a shift (z) of the eye of the observer. The different images show how the different positions of the display illuminate the eye box. By column, from left to right, there is shown a left high position, a high right position, the middle of the display, a left low position and a low right position, from left to right. The first line 800 shows the illumination for an observer at the design distance for which the HUD optics is set. The eye box is illuminated regularly by each display point.
    The second line 802 shows the illumination for an increased distance of 8 cm between the eye of the observer and the windshield. While the central display point is still observed from each position in the eye box, the offset of the eye boxes for the marginal areas of the display deviates from the destination position. Without compensating, you can no longer observe the entire content of the image in the marginal areas of the eye box.
    The last line 804 shows the lighting with compensation by the offset of the LED. The LED was brought 3 cm closer to the display in the middle of the display from the initial distance of 26 cm. As the picture shows, the drift of the eye boxes will be largely compensated by the offset of the LED.
    FIG. 9 shows a very simplified flow chart of a method 900 for adjusting the field of view of a field of view display apparatus according to an exemplary embodiment of the invention. The method 900 consists of a step 902 in which the information of the position of the eye is recorded. This position information of the eye is, for example, in the form of data or an electrical signal arriving through an interface. The position information of the eye contains information relating to the position of at least one eye of the observer using the field of view display apparatus. In step 904, the position of the light source of the field of view display apparatus is matched to the optics of this apparatus if the eye information indicates that the position of the Observer's eye of the field of view is beyond the tolerance range associated with this field of view.
