Abstract
Abstract An image processing apparatus comprises: a receiving circuit to receive image signals of a plurality of colors, in which the image signals is received for every color by an amount of one image formation unit such as one picture plane; a detector to detect whether the image signals have properly been received by the receiving circuit or not; and an image forming device to form a color image on the basis of the image signals, wherein the image forming process by the image forming device is executed in accordance with the result of the detection by the detector. Even if a communication error was generated, a good color image can be reproduced.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
126 words
An image processing apparatus comprising: a) receiving means for receiving a plurality of color component signals; b) detecting means for detecting whether the color component signals have properly been received by said receiving means; and c) output means for outputting a plurality of recording signals, including a black signal, to image forming means for forming a plurality of color component images frame-sequentially, wherein said image forming means, last of all, forms a black image, and the result of the detection by said detecting means is displayed in the black image which is, last of all, formed by said image forming means even if the result of the detection is obtained while said image forming means is forming a color component image other than the black image.
Claim 2
Dependent Claim
126 words
