Abstract
An image processing apparatus separates a color original into a plurality of color signal components and sequentially reads the color signal components so as to sequentially form images corresponding to the color signal components on a photosensitive body. At least two color signal components of a color image to be synthesized with the color original are simultaneously read and are stored in an image memory, and upon image synthesis, the color signal components are read out from the image memory in synchronism with the color signal components.
Claims26
A color image processing apparatus comprising:
- supply means for supplying color separation signals corresponding to a plurality of color components;
- and
- processing means for causing at least one of the color separation signals supplied from said supply means to be subjected to density conversion processing different from that for the other ones of the color separation signals;
- wherein said processing means includes means for calculating an average of signals corresponding to a plurality of pixels for the at least one of said color separation signals and means for outputting a signal corresponding to one of a plurality of pixels for the other ones of the color separation signals.
An apparatus according to claim 5, further comprising:
- means for supplying the color separation signals processed by said processing means to a monitor.
An apparatus according to claim 5, further comprising:
- storage means for storing the color separation signals processed by said processing means.
An apparatus according to claim 5, wherein said supply means includes conversion means for converting an image of a color original into an electrical signal.
A color image processing apparatus comprising:
- separation mean for separating an image of an object to be read into a plurality of color signal components;
- first processing means for simultaneously processing the plurality of color signal components separated by said separation means;
- second processing means for sequentially selecting the color signal components separated by said separation means;
- and
- means for synthesizing the signals processed by said first processing means and the signals selected by said second processing means.
A color image processing apparatus comprising:
- separation means for separating an image of an object to be read into a plurality of color signal components;
- first processing means for simultaneously processing said plurality of color signal components separated by said separation means, and performing density conversions of at least one of said plurality of color signal components;
- and
- second processing means for sequentially selecting the color signal components separated by said separation means.
A color image processing apparatus, comprising:
- storage means for storing image data of plural color component signals relating to a predetermined area;
- output means for outputting plural color component signals obtained by converting a color imaged into an electric signal and processing the electric signal;
- selecting means for selecting one of the color component signals output from said output means;
- and
- processing means adapted to select one of said plural color component signals out of said storage means in response to a selection operation of said selecting means, to combine the thus selected color component signal with the color component signal selected by said selecting means, and to supply the thus combined signal to a color printer.
