    摘要： An image processing apparatus for automatically improving the contrast of an input image that is obtained from a digital camera or the like, and obtaining a sharper and clearing image. A contrast improvement unit (11) performs a contrast improvement process on the input image by comparing an object pixel in the input image with pixels in the surrounding area. An image combination unit (12) combines the enhanced image obtained by the contrast improvement process with the input image. The combined image is then output to a desired device such as a printer by an image output unit (13).

    摘要： The following means are adopted in the image processing apparatus according to the present invention. First, an object image separating means separate a color image described in an outputting control language into the command image generated by the drawing command and the photo image generated by the image data having color information per pixel, such as a bitmap data, so that the command image and the photo image are color-processed separately. As for the command images, there is provided command image processing means to color-process color palette information given to a region specified by the drawing command and to generate a first image having color information by the pixel, such as a bitmap image. As for the photo images, there is provided photo image processing means to color-process and generate a second pixel image. In this color-processing, the photo image is divided into a plurality of image blocks. Then at least one kind of colors or representative colors among the colors making up the image block is decided on.

    摘要： The invention relates to the image processing, and more particularly to the image processing method, the image processing apparatus, and the image processing system that compress color data. In order to extract the representative color from a small region on the color image in order to approximate to the color image, the invention performs the calculating of an average and a variance of color data of the small region, the color of which the variance is the largest is determined as a target color. According to the average of the target color, the small region is divided into two sections. After calculating the region information of the two sections and each representative color of section, judging whether the obtained number of representative colors is more than the requested number of colors, if the obtained number is more than the required number of colors, the dividing is completed. If not, the dividing is repeated again.
