Abstract
Abstract There is provided a color image processing apparatus such as a color copier having the function to automatically discriminate whether each original is a black and white original or a color original. Such an apparatus has a discriminating circuit to discriminate the attribute of each original image, a memory to store the discrimination results by the discriminating circuit every original image in correspondence thereto, and a processor to process the relative original images in accordance with the discrimination results stored in the memory. The discrimination result is read out of the memory a plurality of times for the same original and the same original is processed a plurality of times by the processor on the basis of the discrimination result. The apparatus may also has an RDF to sequentially feed originals one by one to the image processing position by the processor. By executing the copying operation on the basis of the discrimination results stored in the memory, the copying time for the page collating copies in the multi-page copying mode in the case of using the RDF can be fairly reduced.
