1. A color image processing system comprising:
- a) a first reading apparatus for converting a first object color image into a first color image signal which is a plane-sequential color signal;
b) a second reading apparatus for converting a second object color image into a second color image signal which is a plane-sequential color signal; and
c) synthesizing means for synthesizing said first and second color image signals,wherein said synthesizing means synthesizes respective color components of the first color image signal output from said first reading apparatus with respective corresponding color components of the second color image signal output from said second reading apparatus; and
d) control means for controlling said first reading apparatus and said second reading apparatus based on a synchronizing signal for each color of said plane-sequential color signal of said first reading apparatus or of said second reading apparatus.

Abstract
There is provided an image processing system in which when two images are synthesized, a first image is transmitted from a first image processing section to a second image processing section and a third image is obtained by synthesizing the first and second images, wherein the system has means for adding image effective area information for synthesization and for transmitting simultaneously with the first image information, and the image synthesization is executed on the basis of the image effective area information.

7. A color image processing system comprising:
-
a) an image forming device for forming a given image signal as a visible image, said image forming device outputting a sync signal for image formation from said image forming device; b) a first reading device for converting an object image into an image signal synchronously with the sync signal which is output from said image forming device; and c) a second reading device for converting an object image into an image signal synchronously with a second sync signal, wherein said first reading device supplies the second sync signal to said second reading device in response to the sync signal which is output from said image forming device. - View Dependent Claims (8, 9, 10, 11, 12, 13)
