Abstract:
1. An image processing apparatus comprising: image reading means for reading original image data; first generating means for generating image data of a first patch image read by said image reading means and sending to a print controller, wherein the print controller generates a first correction data based on the generated image data and a first ideal input/output characteristic of the print controller; and second generating means for generating a second correction data based on image data of a second patch image read by said image reading means and a second ideal input/output characteristic for a copying operation, wherein the second ideal input/output characteristic is different from the first ideal input/output characteristic, wherein image data read by said image reading means is corrected by a controller for the copying operation based on the second correction data, and image data received from an external device is corrected by the print controller based on the first correction data.
