ABSTRACT:
A digital color image to be processed is inputted at a color image input step, image segments are extracted from the input color image at an image-segment extraction step, and data of the extracted image segments is created. Next, image-segment components in each extracted image segment are discriminated at an image-segment discrimination step, and each extracted image segment is subjected to zoom processing, which conforms to the discriminated image-segment component, at an adaptive zoom step, thereby creating a zoomed image of the input image. The zoomed image that has been created is displayed, outputted as a hard copy or delivered to a transmission line at a color image output step. Accordingly, a color image in which image segments having different characteristics are mixed is efficiently processed.
