摘要： A color scanner having two lines of CCD. One of the CCD line is used for scanning green image of a document, and another CCD line is used for scanning red and blue images of the document. In the CCD line for red and blue image scanning, red and blue filters are located alternatively on the pixel sensors in a lined shape. In order to obtain a pixel density corresponding to the red image and blue image as same as that to the green image, each of red and blue image signals is processed from two image signals. The color scanner is provided with a memory to store red and blue image signals so that those signals are processed with next-obtained red and blue image signals. The color scanner also includes a shift register to delay green image signals so that all of red, blue, and green image signals are carried out to a processor simultaneously.

摘要： A color image forming apparatus including a color image reader for optically scanning a document to produce blue, green, and red color separated information, a processor for processing the color separating information supplied by the reader and generating black, yellow, magenta, and cyan color information signals, a rotatable image retainer, and two latent image forming devices for forming latent images at a common region on the image retainer in accordance with the color information signals corresponding to two recording colors. The first latent image is formed by one of the latent image forming devices in synchronization with the scanning of the color image recorder to form a first latent image at a first writing position. The second latent image forming device is delayed to form the second latent image at a second writing position. The delay device compensates for the time necessary for the common region on the image retainer to travel between the first and second writing positions. The apparatus further includes a number of developers, each developer being used to develop one of the latent images, thereby forming a multicolor image composed of multiple toner images on the image retainer. Two color latent images, corresponding to two of the color information signals, are formed on the image retainer and developed by the developing means during the first rotation of the image retainer corresponding to a first optical scanning of the document, and the remaining two color latent images, corresponding to the remaining two color information signals are formed on the image retainer and developed by the developing devices during a second rotation of the image retainer corresponding to a second scanning of the document. All the toner images are then simultaneously transferred to the transfer sheet.

摘要： In an image forming machine, density data of small pixels in an objective pixel determined according to density of pixels adjoining the objective pixels, the objective pixel determines a recording position for each color based on density distribution of the adjoining pixels when the recording position of each color is modulated in the primary scanning direction and secondary scanning direction based on density distribution of both the objective pixel and the adjoining pixels. Further, there are provided an image discriminator for image judgment on the objective pixel and a modulator for modulating a recording position using a reference wave with a long cycle when an image is judged to be a halftone image area under a reference wave with a short cycle when an image is judged to be a character image area.

摘要： In a method of forming an image in a form of pixels, the density distribution around a target pixel is obtained by processing image signals of pixels neighboring the target pixel. The target pixel is sub-divided into a plurality of sub-pixels which form of matrix of n rows.times.m columns. The sub density distribution of the sub-pixels in the target pixel is assumed from the density distribution of the neighboring pixels. The density of each of sub-pixels is determined by multiplying the density of the target pixel, by a constant P and a density ratio of the corresponding sub-pixels in the sub density distribution.
