処理装置。 In an image processing device that performs image processing by digitizing the color signal and brightness signal of each pixel output from a television camera and calculating the chromaticity of each pixel, the reciprocal value of all the brightness signals that can be output is calculated. It is equipped with a memory held as a data table and an arithmetic processor capable of multiplication of digital values, reads out the reciprocal value from the data table in the memory based on the luminance signal output from the television camera, and calculates the reciprocal value. An image processing device characterized in that the chromaticity is determined by multiplying the digital value of the color signal obtained by direct memory access by the arithmetic processor.
