    Around point A is formed the first color space B is recognized by g-sh colors (test points with a color number) and around a color test point B is the second space G of color recognition (test points with color number 2) s which are separated from each other by the boundary line D.
    When rechecking the filling of the storage unit 6 of the measurement unit in the color original 21 colors, block 13 records color number 2. This color can correspond to the test point E on the color plane (Fig. Pro). It is desirable that the measured colors and their spatial environment are not assigned to the color recognition space G but to the space B with the color number 1. In this case, the boundary line D is shifted to the region of the color point E in the direction of the color point B of the main sample. For more consistency, the color original 21 is taken only one additional coffin point. The number of additional probes can be any and depends B mainly on the required 1; correction. For additional samples, neither fig.zb may correspond to an additional test point.

    additional sample, which also corresponds to the color number 1. Thus, it retains the color-: number that is defined for it during the initial filling. However, the corresponding color test point is now the color additional test point, which, taking into account all the color test points, i.e. all color points of the primary and secondary samples, affects the environment of the color space. In order to simplify further, the discussion of colors of test points will be 15 in the case when a collection of all the color points of the main and additional samples is implied. The color points of the additional sample, in accordance with their position, must not coincide with the points to be corrected, but only be located in the spatial environment of the necessary border correction. The color points of the additional sample can be assigned any color numbers.
    The taking of additional test points is carried out as follows.
    The operator, using element 16, removes one or several characteristic additional test points in the color original 21, and digitized analog-digital converters 3, 4 and 5 color components, and 35 Z (15 bits) via the address bus 19 is fed to the input of the memory 8. At the same time, the operator composes a table of additional samples and using the keyboard of the device 7, 0, 0, each phosphor triplet of chromaticity coordinates, a color number (A bits) that is fed to the data input 22 via bus 23 In 8.
    45
    Each row of the table of Additional Test Cards under the current addresses, which are called up by block 11 via address bus 24, is stored in the memory 8 as a 19-50 bit memory word. For this, the operator, in the interval, is not expected by separate test points presses the test key of device test 7, for which the corresponding command, 55, which stops on the bus 25 to the input of the unit P., increases the memory address by 1. The composition of the table, thus, of additional test points with 104
    The marking can be entered into the memory of the memory 8 as an independent table or as an addition to the original table of basic test points.
    After taking additional color test points from the color original 21, the originally determined color numbers for the corresponding color points of the additional sample should be erased (the process is shown in FIG. 3b for an additional test point G). For this, the erase area 3 is determined around the additional test point G, and all the color points lying inside the erase area 3 are denoted by the color number O.
    The initial boundary line D is indicated in FIG. 3b inside the erase area 3 as a dashed line. The length of the erase area determines the correction effect of the additional test points on the color recognition spaces previously formed. Erase areas can be spherical, or rectangular, or any other spatial form.
    The process of erasing color numbers in memory 6 proceeds as follows.
    The erasing process starts after pressing the Erase device 7 key, as a result of which the erase command is transmitted to the input of the unit 11 and the computing device 10 via bus 26. In accordance with FIG. 3b, the erase areas are assumed to be ball-shaped. The coordinates X ;, YI, Z (the chromaticities lying inside the spherical regions erasing the color points or the addresses of the memory can be caused line-by-line or shell-wise and denoted by the color number O. In this case, spherical shells form around separate additional test points, while the corresponding memory addresses are read casing behind casing with increasing interval until the peripheral zone of the erasure region is reached.

    The coordinates of the shells are entered in the form of a table of shells in memory 9, and the coordinates of the chromaticity will be added to & ny test points as a table in memory 8,
    To interrogate the data of the tables, block I is connected via address buses 24 and 27 to memory 8 and 9. Coordinates Hd. Yg, and Zg of the shell via bus 285 and the coordinates and chromaticities of the additional test points via bus 29 are rewritten into the calculation: the output device 10, and based on this, the coordinates Y needed to form the shell are calculated; and Z chroma.
    When shells are formed, they alternately form the first shell around each individual color point, then the second shell, and so on. The formation of all shells around one color additional test point is possible, and then all the shells around the following color additional test points, etc.,
    Coordinates X; 5 Y; and Z: chromaticity; which, via the bus 30 and the switch 20, arrive at the address input 31, cause the corresponding addresses of the storage device b, which carry out the distribution of color numbers O through the bus 32 into the valve circuit 12,

    From the shortest distance dn,; subsequently get the necessary radius g area of erasure.
    The radius g of the erase area can also be determined with the infirmity of the analysis of the color original 2. For this purpose, the operator, using the read element 16, determines the coordinates X, Yf. and Zy, the color of that color of the color original 21, which should not be changed by an additional test point, which lies on the periphery of the erase area around this additional test point. Then according
    106
    The formation of shells around the additional test points, denoted by the numbers O, is interrupted when the erase area reaches the desired distribution. Then, the input Terminating the polling of the table of shells and the table of additional test points is sent to the input 33 to block 11
    The spreading of the erase area can be interrupted by touching the erase area or when the erase area is reached. The radius g of the erase area can, for example, be set by the operator equal or different for all erase areas (supplied to the software input 34 of the computing device 10). The erase area radius for an additional color test point can also be determined independently as a fraction of the spatial distance d corresponding color additional test point and color test point, located in the greatest proximity; which is given a color number that is different from the color number of the corresponding color test sample point. To do this, call the coordinates X-, p, and Zvp of the corresponding color points from the table of additional sample points, successively output all the coordinates Xp, Yp and Zn of the table of the main and auxiliary test points of the memory 8 and determine in the computing device 10 distances according to the vector distance equation:
    (P - z, p)
    (one)
    with the reduced vector equation (1), the distances are from the coordinates X, Yp: Z., and, and the nondigit radius of the erase area is calculated. To form a spherical area, e H erase around one additional test point, successively call the coordinates or memory addresses of all the target points, determine the spatial distance d between the main test point t currently called, compare it with the specified or calculated m radius. the area of the ster ;; nile. Whit color points
    (addresses), the distance between which is less than the radius r of the erase area, is located inside the erase area and, as noted above, they are assigned a color Number O. Then the process repeats the next additional test point.
    This process proceeds as follows.
    The coordinates Xr, and the additional test point dve are transmitted from the 8 additional test points embedded in the memory device to the computing device 10. Block P calls all the possible X, Y coordinates; and Z colors that provide line-by-line addressing of the storage device 6 via the address bus 30. At the same time, the requested color coordinates through the pin 35 are sent to the computing device 10, where the distance calculation process described above proceeds.
    After forming around the additional test point of the erase areas for the color test points lying inside the erase areas, the new color numbers are independently determined.
    Fig. 3b shows the chromaticity level after re-filling the erase area 3 around an additional test point G. The color recognition space B with color number 1 spreads into color recognition space G with color number 2, thereby forming a new boundary line D. The former boundary line D and the original erase area 3 are shown in dashed lines. The corrected color point E, including its environment, is now uniquely assigned to the color recognition space B with color number 1.
    Re-filling is as follows.
    First of all, all previously specified color numbers are assigned to all color points of an additional sample or their memory addresses. To do this, using block 11 from memory 8, buses 29 and 36 transfer all colors of the numbers and chromaticity coordinates of the additional test points of the table to the computing device 10. Coordinates, Yj, p and colors of additional test points provide addressing via address bus 30 The memory 6, and the corresponding color numbers of the additional color test point g, via the bus 32, the valve circuit 12 and the data input input 37 are transmitted to the input of the memory 6. Then, the shell erase is filled again.
    0 All color points or memory addresses that form a shell around the test color points (both primary and secondary), shell by shell, are alternately read from
    5 by growing intervals from the respective color test points and rechecked to the color number O (area of erasure). If, when calling a color point, it corresponds to a color
    0 number O, this color point is assigned a color number corresponding to the central color test point. Around the first; a first spherical shell is formed,
    5, then a second, etc., while the computing device 10 calls the required coordinates X ;, Y; and Z; chromaticity. The shell table for the first spherical shell through tire 28 is inserted into the computing device 10, and the table of additional test points, including the table of basic test points, is subjected to line-by-line processing, the X, Y coordinates are sequentially calculated; and Z; the colors of the first spherical shell around each test point. These color coordinates also provide memory addressing 6. Simultaneously
    0, a recheck of each addressed cell of memory 6 is carried out for the loading of a color number, taking into account the possibility that this has already happened. For this, valve diagram 2 through
    5, the information bus 38 is connected to the output 39 of the data of the storage device 6. If loading takes place, then the valve circuit 12 is blocked, so that no color number can be recorded via the bus 32 in the storage device 6. If there is no loading (color number O), then the valve circuit 12 is unlocked under the address that is being called at a given time,
    5, the color numbers of the color test points are memorized to form a spherical shell. Thus, around individual color test points, see
    9I
    more ball shells that continue until the color numbers are assigned to the erase areas again.
    All addresses of the storage device can also be called line-by-line once by block 1 through address 1 and 30 and rechecked to color numbers O using gate circuit 2. When the address with color number O is detected, it is about the address of the erase area, and the gate circuit 12 transmits the Erase Region command via bus 40 to the input of unit II, thereby marking the corresponding addresses and interrupting the process of further calling the addresses. In the computing device 10, a color test point lying adjacent to the marked color point and their color numbers are laid down via the bus 32 and the valve circuit 12 below the marked address. Then, the next address is set with the color number O and the distance is also determined for this address. The process lasts until all the erasures are assigned color numbers.
    For coarse additional correction of the color recognition spaces, the read element 16, making dashed movements in areas lying close to each other, moves over the part of the color original 21 to be corrected in order to cover the largest possible number of luminous triplets of the color coordinates of this area. Switch 20 is in the working position (position indicated by a dashed line), and the color coordinates are chosen directly by the corresponding addresses of the storage device 6. Simultaneously with the movement of the read element 16, the operator using the decimal keyboard enters new color numbers into the device BC1 7. This should be distributed under all called addresses in the & x 6 memory.
    In the future, separate chromaticity color space color levels — color depending on the luminance values (color coordinate Z) or individual accumulated levels; color memory 6 — are displayed on the monitor;

    WA correction. Each color point and each memory address correspond to one image point. Color numbers can be assigned to freely selectable colors, so that each color recognition space (color dots of the same color numbers) is characterized by a specific color. Thus, on the screen of the color monitor 44, current levels can be represented as planes passing through separate color recognition spaces, perpendicular to the Z axis and having different colors. Partial correction of the color recognition space in each section level can now be carried out using a correction device.
    The color numbers required for presentation are selected from the data array of the information carrier 50 and from there, with the support of the computing device 47, via the buses 51 and 57 are loaded into the image repeating memory 41. The process of synchronous addressing of the information carrier 50 and the memory 41 is controlled by the computing device 47 through the address buses 52 and 53.
    The storage medium 50 may be a storage device 6 or a magnetic disk (flexible), to which the contents of storage device 6 have been previously written.
    In order to display the chroma color levels on the monitor screen 44 as a slice image, the computing device 47 through the address bus 53 performs a cyclic call to the addresses of the storage device 41, and line-by-line reading of the color numbers stored in the memory device occurs within each line.
    In the color sensor 42 each color number can be assigned a freely selectable color or its signal g, g, b. The color numbers read from the memory 41 via the bus 58 are fed to the input of the color sensor 42, which transfers the previously transmitted ch, g, and b signals to the input of the monitor 47.
    The recording is performed by the interlaced scanning method to obtain a flicker-free image. The generator 46 clock pulses in the usual way for television technology produces the necessary recording
    the images are horizontal and vertical signals and lowercase and personnel trigger pulses that enter the multi-wire line 59. Computing device 47 generates sync pulses that go through bus 55 to the input of clock generator 46 so that the read and write processes of the image flow synchronously.
    The markings of the point of the image or address in the memory 41 are carried out by flashing the light mark 45 on the screen 44, which can move along the screen plane by specifying the X, Y coordinates by the block 48. The specified X, Y coordinates are entered into the computing device 47 through the bus 54 compared with the cyclically called addresses of the memory 41. In the case of equality, the computing device 47 sends the Light label command to the signal generator 43 in the color, g, g and b signal paths via the bus 56. The command is issued at the moment when the electron beams pass through the screen areas marked with the given coordinates. At this moment in time, due to the short-term simultaneous switching on of all the color signals with the same brightness, a luminous mark appears. At the same time, the light label 45 marks the cell of memory 41, which is directly accessed.
    By partial correction of the presented section planes, the operator, using block 48, performs the marks of the areas to be corrected and, using the keyboard of block 49, via the bus 59, enters the desired color numbers into the computing device 47.
    During the blanking interval of the image recording, the computing device 47 through the address bus 53 addresses the addresses 41 indicated by the block 48 or the light mark 45, and the changed color numbers through the bus 57 are distributed under the called addresses. At the subsequent repetition of the image on the screen of the color monitor 44, an already corrected color image appears.
    The proposed method improves the accuracy of color recognition of the color plane. .
