ABSTRACT:
When an image subjected to color conversion processing is to be previewed on a monitor (217), image data are supplied from a synthesis unit (206) to an image memory unit (217). When an image subjected to paint or free color processing in an edit circuit (213) or an image synthesized by the synthesis unit (206) is to be previewed, an inverse LOG table for converting C, M, Y, and K image data into R, G, and B image data is set in a gamma correction unit (214), and image data are supplied from an edge emphasis unit (215) to the image memory unit (217). Therefore, a storage means can be used by methods suitable for both the image forming mode and the monitor display mode.
