PROBLEM TO BE SOLVED: To provide an image processor capable of performing processing in plural types of synthesis methods with a single circuit configuration.SOLUTION: When creating a composite image of an upper image and a lower image, conversion characteristics of a polygonal line circuit are set according to pixel value corresponding pixels in a synthesis method and the lower image; and pixel values of the upper image are converted according to the convert characteristics with which the polygonal line is set to obtain pixel value of a composite image. By properly setting polygonal line characteristics according to the synthesis method and pixel values of the lower image, various kinds of synthesis processing method are made possible using a single circuit configuration.SELECTED DRAWING: Figure 1 |
