    Signing signals. These synchronizing signals are also supplied to the counter 23 rows of the counter 24 image points, which are also fed from the microprocessor 25. The signals from the outputs of the 23 row counter and 24 image counter counters are supplied by the control unit 9, the control signals from which are fed to the control inputs of the gates 11-18, which let or not pass the video information. From the information output of the microprocessor 25, the signal is fed to the inputs of the first to fourth memory blocks 2-5, respectively, in which the video information is stored. If the corresponding inverse signal from the control unit 9 is supplied to the control inputs of the fifth and eighth gates 15-18, these gates pass the video information from the first to the fourth memory blocks 2-5 through the converter 6 of the Y, M, C and K signals, respectively. to R, G and B signals and 8 digit converter - analogue to video control unit 7.
    The coordinate signal setting unit 27 generates a signal with the possibility of transmitting, the microprocessor 25, the input unit 26, 30, moving across the screen of the color video signal of the reference color signal, the coordinate signal setting unit 27.
    A device for monitoring and correcting the color image signal works as follows.
    In the imager 1 of the Y, M, C, and K color image signals, four color-separated image signals are generated for
    roll block The first to fourth memory blocks 2-5 form on the screen of the video monitoring unit 7 a reference image in the form of a frame on a color jr field, while the size of the frame can vary and be moved. The input signal block 26 — the reference colors — is intended for input via the microprocessor 25 and converter 6 of signals Y, M, C and
    colors: yellow - Y, magenta - M, blue 40 K in the R, G and B signals of the color image
    C and black - K. These signals arrive at the first inputs of the first - fourth elements, respectively, OR 19-22, respectively, through the first - fourth valves 11-14. C is 45 in those cases when within
    of the moves of the corresponding elements OR 19–22, the signals Y, M, C and K are fed to the converter 6 of the signals Y, M, C and K to the signals R, G and B, which through the converter B digit - analogue arrive at the video monitoring unit 7, on the screen of which a color still image is formed. In this case the shaper 1 of the Y, M, C and K signals of the color image, the converter 6 of the signals Y, M, C and K into the signals R, G and B and the video monitoring unit 7 are controlled from the clock sensor 10, which gives sync

    Signing signals. These synchronizing signals are also supplied to the counter 23 rows of the counter 24 image points, which are also fed from the microprocessor 25. The signals from the outputs of the 23 row counter and 24 image counter counters are supplied by the control unit 9, the control signals from which are fed to the control inputs of the gates 11-18, which let or not pass the video information. From the information output of the microprocessor 25, the signal is fed to the inputs of the first to fourth memory blocks 2-5, respectively, in which the video information is stored. If the corresponding inverse signal from the control unit 9 is supplied to the control inputs of the fifth and eighth gates 15-18, these gates pass the video information from the first to the fourth memory blocks 2-5 through the converter 6 of the Y, M, C and K signals, respectively. to R, G and B signals and 8 digit converter - analogue to video control unit 7.
    The coordinate signal setting unit 27 generates a signal that can be moved around the screen of a color video monitor unit. The first to fourth memory blocks 2-5 form on the screen of the video monitoring unit 7 a reference image in the form of a frame in a color field, and the size of the frame can vary and be moved. The input signal block 26 — the reference colors — is intended for input via the microprocessor 25 and converter 6 of signals Y, M, C and
    send signals that change the saturation of the reference colors on the screen of the video monitor unit 7.
    The proposed device using the color field. The color part of the image must be corrected by a specific color value.
