Abstract: An image processing method and apparatus for obtaining, from an original image, a natural mosaic image or an image of neo-impressionistic effect. In this method and apparatus, image information of one pixel is converted into information of a block of plural pixels (multi-level data), and the latter information is arranged randomly in the block.

Abstract: There is an image processing apparatus to obtain a desired processed image by performing a predetermined image process to an input image. This apparatus comprises: an image input unit to input the image data; an image processor which can perform different image processes; a selector to select the kind of image process to be executed by the image processor; a memory to store different sample processed images which were subjected to the image processes; and a display to display both a sample image before execution of the image process and the sample processed image corresponding to the selected image process from the memory in accordance with selection by the selector. The image processor can perform the edge extracting process, mosaic process, and the like. With this apparatus, the operator can easily obtain various sample processed images and can extend the processed image of the original image by merely inputting a processing command.
