Abstract
A color information converting device for use in a color image recorder for processing image density signals each being representative of a particular color-separated image density to produce a record density signal representative of the record density of black, cyan, magenta or yellow. The device adds an undercolor to an image easily with a simple and inexpensive construction and produces a record density signal representative of full black or skeleton black also easily with a simple and inexpensive construction. In a full-color record mode, image density signals are transformed into record density signals by constants which are associated with the values of the image density signals while, in a monocolor record mode, the former is transformed into the latter by constants which are not related to the values of the image density signals. This implements combined full-color and monocolor recording which is excellent in color-reproducibility.
