ABSTRACT:
An image processing apparatus in which the amount of data bits for each of plural block units is controlled to be the same for all block units, so as to facilitate location of each block unit in coded image data without necessarily decoding the entire image. Pixel image data which is formable into plural block units is input for each block unit, and the input image data is orthogonally transformed. The orthogonally-transformed image data is quantized, and variable-length coding is performed on the quantized image data so as to generate variable-length code. The amount of variable length code in each block unit is controlled to be no more than a predetermined amount of data bits, with the predetermined amount being the same for each block unit.
