Abstract
There is disclosed an image processing system, particularly, for use in a copying machine with a display. This apparatus comprises a liquid crystal display panel on an original presser plate; a panel copy mode to perform the image processing with respect to the screen display; an ordinary copy mode to perform the image processing with respect to an ordinary original; a high gradient processor to perform the image processing of high gradient; a low gradient processor to perform the image processing of low gradient; and a switching circuit to switch the high gradient processor and low gradient processor in accordance with the panel copy mode and ordinary copy mode. The image processings with different gradients can be executed depending upon the states and kinds of originals, so that an appropriate copy of the display panel or ordinary original can be always provided.
