SYSTEM FOR CORRECTING INPUT ERROR AT TIME OF CAMERA INPUT

PURPOSE:To improve the quality of an input level by storing the dispersion of red(R), green(G) and blue(B) signals for each picture element of an input image due to an illumination into a correcting value memory, and correcting the error of the input level from a camera to an image device. CONSTITUTION:At the time of an output to a display (CRT) 10, the contents of a correction memory 5 and a bit map memory are made into addresses, a look-up table(LUT) 8 to store a correction curve to be set beforehand is read, the output is converted to an analog signal by a digital/analog converter(D /A), and it is displayed on the display (CRT) 10. Consequently, the dispersion of the illumination and the dispersion of red (R), green (G) and blue (B) outputs by an amplifier and an analog/digital converter(A/D) are corrected, and they are outputted. Thus, by using the output signal, at the time of, for example, preparing the still image of a camera for a captain system, input image data with a good quality can be obtained.
