Abstract

A digital color copying machine including a mosaic monitor mode is disclosed. In the mosaic monitor mode, image data corresponding to a partial area of an original document is stored in a RAM. The image data is then read repeatedly from the RAM and a plurality of images of the partial area which have been subjected to different color adjustments are formed on a recording medium, so as to form a mosaic monitor image. The operator may then choose a desired color adjustment from the plurality of color adjusted images. Also, an operator may vary a parameter in the color adjustment process to obtain either greater or more minute color adjustments.
