A color image encoder comprises a block converter for dividing a digital color video signal, which is composed of a Y signal and R-Y and B-Y signals, into blocks for the respective signals; an orthogonal transformer for orthogonally transforming the digital image video signal divided into the blocks, for each block, to produce orthogonal transform coefficients; a quantizer for quantizing the orthogonal transform coefficients; a variable length encoder for coding the quantized orthogonal transform coefficients to produce a code sequence; a generator code length counter for counting the length of the code sequence; a chrominance signal inspection circuit for calculating an absolute value of a difference between an average of pixel values in each block of at least one of the two chrominance signals and a value in an achromatic level of the chrominance signal, detecting a maximum value from the absolute values obtained in a unit of a collection of pixels for which a quantization scale u...
