ABSTRACT:
An image processing apparatus functions to convert a first image derived as color-pixel data into a second image generated by a lesser number of corresponding data through a pixel-skipping process. The first image data is segmented into pixel blocks each consisting of a plurality of the color-pixel data relative to the number of second-image pixels to be generated. Each pixel block corresponds to one pixel composing the second image, and serves as an objective block from which the data to produce the corresponding second-image pixel is determined. If this determination cannot be made, the relevant color-pixel data is determined by comparative reference to color data of both the objective pixel block and that of adjacent pixel blocks. Original dot and fine-line features of the first image are thus maintained in the pixel-skipped second image.
