Abstract
Abstract A color image processing apparatus comprises: a device to supply color image data obtained by photoelectrically converting an object image; a changing circuit which has a density conversion table and changes the density of the color image data supplied by the supplying device into a plurality of densities on the basis of the table; and a reproducing device such as a bubble jet printer for reproducing the image data whose density was changed by the changing circuit as a plurality of visible images which can be simultaneously seen. With the apparatus, an image of a desired color or density can be preferably reproduced.
