Abstract

An image processing apparatus has CCDs for reading image data of an original, an edge detector for detecting edges of an area specified on the original with a loop or marks of a specific color, an area detector for detecting the specified area, memories for storing the image data read by the CCDs, and a data selector and a data switching circuit for selecting the image data read by one of the CCDs which is to be supplied to an inkjet head for recording. For preventing contamination of the original, the loop or marks can be drawn on the original through an original cover including a transparent or semitransparent sheet member facing the image of the original. Images inside and outside the area or areas can be selectively reproduced in various combinations of the normal mode, red output modes involving different types of color conversion, and extinguishing mode. Image data from another source which is stored in another memory can be inserted at a desired part of the reproduced copy.
