  • Patent number: 4879595
    Abstract: A color image processing technique using optics to separate an original color image into a plurality of colors. These colors are photoelectrically converted to electric signals. Color information signals are then generated from these electric signals. The color information signals are coded by comparing them with a threshold value. An individualized set of such threshold values is provided for each of the plurality of colors. In one embodiment, a luminance signal is provided from the color information signals. The luminance signal is utilized in response to a monochrome code selection signal to enable the original color image to be reproduced as a monochrome image. Color gamut information and color density information of the color gamut can be obtained from the color information signals during a first scan of a document bearing the color image.

  • Patent number: 4878110
    Abstract: In a color image processing apparatus according to the invention, a color image signal being photoelectrically obtained by a image reader is separated into red, blue and black color component signals. A laser scanner writes respective latent images corresponding to the color component signals on a cylindrical photoreceptor. Each of the respective latent images are written during one rotation of the photoreceptor. The initial writing positions of the respective latent images are registered by using a drum index signal generated in synchronization with the rotation of the photoreceptor. An optical output starts outputting an optical signal in response to the index signal or an encoder signal selected according to the copy mode.
