摘要： In an image processing apparatus according to the present invention, the density of each pixel in a multi-level pixel block composed of a set of input multi-level pixel data is examined and a decision is made as to whether a pixel having a density which does not reach the minimum density below which printing is impossible, is present in the multi-level pixel block. If a pixel having a density below the minimum density is detected, the density of this pixel is distributed to another pixel position in the multi-level pixel block. In this manner, the number of pixels with a density which does not reach the minimum density below which printing is impossible, is reduced within each multi-level pixel block.

摘要： A color image processing apparatus includes arranging means for arranging intervals between dot positions on a scanning line at which dots are formed, and shifting means for shifting the dot positions on the scanning line by a shifting amount. At least one of the intervals and the shifting amount for a first color component are different from an interval and a shifting amount of a second color component. The processing apparatus also includes control means for controlling the arranging means and the shifting means so that n (n.gtoreq.3) adjacent dot positions at which the first color component and the second color component overlap correspond to vertices of a substantially regular polygon having n vertices.
