Image processing apparatus and method
First Claim
1. An image processing method comprising the steps of:
- inputting a color image;
extracting an image area, which has a characteristic different from a background image area of the input color image, from said color image; and
discriminating the characteristic of the extracted image area,wherein in said extracting step, the image area is extracted by recursively repeating that a background image area is separated from an area to undergo processing in the input color image and at least one image area is separated from image areas other than said background image area.

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.

16. An image processing apparatus comprising:
-
input means for inputting a color image; extraction means for extracting an image area, which has a characteristic different from a background image area of the input color image, from said color image; and discrimination means for discriminating the characteristic of the extracted image area, wherein said extraction means comprises first separation means for separating a background image area from an area to undergo processing in the input color image and second separation means for separating at least one image area from image areas other than said background image area, in the extraction process executed by said extraction means, the image area is extracted by recursively repeating processes executed by said first and second separation means. - View Dependent Claims (17, 18, 19)

20. A computer program product comprising a computer readable medium having computer program codes for executing an image processing method, said product comprising:
-
input process procedure code for inputting a color image; extraction process procedure code for extracting an image area, which has a characteristic different from a background image area of the input color image, from said color image; and discrimination process procedure code for discriminating the characteristic of an extracted image area, wherein in said extraction process, the image area is extracted by recursively repeating that a background image area is separated from an area to undergo processing in the input color image and at least one image area is separated from image areas other than said background image area.
