摘要： In a method of controlling the sub-scanning of a document reading apparatus the speed, acceleration or deceleration of the reading section is controlled according to the amount of information stored in a buffer memory which temporarily stores information read by the reading section. The values of the movement speeds, accelerations and decelerations are predetermined according to the stored information amount of the buffer memory and at the time of controlling the reading section, one of these values is selected according to the currently stored information amount of the buffer memory. Whereby any vibration in a reading section is prevented to eliminate the irregularity in the sub-scanning of the reading section.

摘要： A color copying machine includes a device separating the image information from each area of the original into colors corresponding to predetermined recording colors to thereby form corresponding video signals. A preferential selection circuit converts each video signal into a 2-level signal and performs an arithmetic operation on each 2-level signal to thereby key the image information from each area of the original to one of the recording colors or white. Black is selected as the recording color if a chromatic color competes with black in the same area.

摘要： A multi-function copying machine having a reading section for reading picture data on an original by raster scanning. A recording section has a plurality of recording devices adapted to perform recording at different recording positions. The recording section applies to the recording devices a picture signal for each color for multi-color recording or a picture signal for each side of the original for two-side recording. Recording control is achieved by a control system for controlling the timing of delivery of the picture signal applied to the recording devices. An editing control circuit sets the timing of delivery of a part of the picture signal provided by the reading section to the recording section, for editing the picture data on the original. A memory delays the timing of delivery of a predetermined picture signal to the recording section according to the timing of delivery set by the control system.

摘要： A method and apparatus for correcting the photoelectric converter of a document reading unit for non-linearities produced by the optics of the system. A test document having no image data thereon is scanned to produce a shade correction signal which is subjected to A/D conversion and stored in a memory. In binary-encoding the picture data of the original, a switch is operated according to the data stored in the memory so as to change a threshold level for the picture signal, whereby digital picture data whose shading has been corrected is obtained. In the case where the picture data of the original are represented by an analog signal, the picture data are also subjected to A/D conversion, and division is carried out with the data stored in the memory being employed as dividends. From the results of such a division, corrected multi-level picture data is obtained.
