摘要:
A color image processing apparatus includes line sensors and an A/D converter for entering color-sequential image data in which plural color component signals are sequentially arranged, a first converter for converting the color-sequential image data into parallel image data, a color image processor for effecting color image processing on the parallel image data obtained from the first converter, a second converter for converting the parallel image data into color-sequential image data, and a device for supplying the color-sequential image data converted by the second converter to the color-sequential image data processor at a next stage in the processing of the color component signals.
摘要:
There is disclosed an image reading apparatus capable of preparing unsharp mask data from an image with a simple structure. For this purpose there is employed a first line sensor with plural photoelectric converting elements, and a second line sensor with larger photoelectric converting elements of a greater length, both being arranged parallel and desired data being obtained by processing the signal from these sensors.

An image processing apparatus comprises image data input means and processing means for processing an input image data. The processing means includes image content discrimination means for discriminating whether the input image data represents a half-tone image, a line image or a combination thereof.
摘要:
A data processing system, in which image data is transmitted in units of predetermined length, e.g., a predetermined number of lines, and code data comprising a character or the like, is transmitted in units each of which contains the code data corresponding to the predetermined unit of the image data. The image and the code data are preferably transmitted on a common transmission channel, and can be separated upon reception for separate processing.

A color recording method allows digital color recording by calculating fractional areas to be covered by each color used in recording. A plurality of sets of area factors for the colors are calculated from a plurality of sets of color equations corresponding to a plurality of sets of magnitude relationships between the area factors. One set of area factors having the same magnitude relationships as the set of magnitude relationships corresponding to the set of color equations from which the one set of area factors was calculated is selected for color image production. The colors can consist, for example, of three subtractive primary colors or of black and two subtractive primary colors, in different superposition combinations. A color recording apparatus has a camera, a processor, a memory and a printer. Reflectivities of inks of different colors are measured and substituted in the color equations. An optimum color image is produced, compensated for differences between input and output system characteristics.

A copying method and apparatus in which a first and a second original image are prestored in a memory, and a desired number of volumes is set for copying that number of volumes with the copies of the first and second original images stored in the memory as one volume. The first and second original images are successively read out from the memory when the set number of volumes is plural. The read-out images are successively printed on a first and a second copy medium and the read-out and print of the first and second original images are repeated over the times corresponding to the set number, thereby producing a desired number of volumes of copies having the first and second original images arranged in order of the page number.

This invention is directed to an electrophotographic copying machine capable of copying small originals such as ID cards. The copying machine includes a recording medium carrier having a cover by which a recording medium is placed within the carrier at a first location before the copying operation is begun and guide rails along which the enclosed recording medium is then driven for the imposition of a uniform charge and a latent image to a second location where the cover is opened and the recording medium is removed and developed while the carrier is returned to the first location.
