Abstract: The present invention adopts a configuration making a decision on a half-tone dot image focused on cyclicity of an image of a half-tone dot decision information adding circuit 102 on an image input from an image reader 101 in advance, adding the decision result to the image as half-tone dot decision information and carrying out various kinds of image processing using the image data in an arbitrary order. Image processing blocks 103, 104 and 105 store added half-tone dot decision information and transmit the half-tone dot decision information to the next block. The scaling circuit 104 is constructed in such a way as to decide, in the case of scale-up, half-tone dot decision information scaled up based on the output pixel position and half-tone dot decision information before and after the pixel position and decide, in the case of scale-down, half-tone dot decision information scaled down by decision by majority or under an OR condition of the half-tone dot decision information within the input pixel range corresponding to one pixel output.

Abstract: The image processing apparatus transforms orthogonal transform coefficients into a predetermined number of bits for each spatial frequency, rearranges quantized data for each spatial frequency to an arrangement with spatial frequency band portions, thereby generates bit serial data that the quantized data of the same spatial frequency band exists successively over adjacent blocks, and compresses the bit serial data.
