Title: Method for converting color picture data into binary contrast value
Inventor: KUBOTA YASUO
IPC: H04N1/52
Filed: 1985-03-11
Abstract: PURPOSE:To minimize the overlapping of respective color dots by applying converting processing to each color while adopting different arranging angles of dot patterns for each color in applying binary contrast converting to each primary color source data of a color contrast picture by means of an area gradation dot pattern. CONSTITUTION:Color filters red (R), green (G) and blue (B) are mounted on a camera to extract contrast picture data, which is converted into a digital signal and stored in a memory. For example, 8-bit gradation (256 gradations) is applied to contrast with respect to each picture element, the gradation data is written on each address of the memory with respect to all the pictures to form each color source data and the binary contrast converting processing is applied based thereupon. Each dot pattern is arranged to attain coincidence with the dot pattern arranging angle decided for each color. In case of a 4X4 dot pattern, the interval between adjacent dot patterns is deviated laterally or longitudinally by minimum one-dot share and maximum 4-dot share so that the imaginary line tying sequentially the center positions of the dot pattern keeps a prescribed angle to the longitudinal and lateral sides of the input picture data.

Title: Pattern recognizing device
Inventor: TOYODA HARUYOSHI
IPC: G02B27/46
Filed: 1993-03-09
Abstract: PURPOSE:To attain pattern recognition having a high SN ratio by mutually comparing the detection outputs of two detectors having respectively different areas and detecting coincidence between plural patterns. CONSTITUTION:Detectors 140a 140b are arranged on the focus face 142 of a lens 124 and consist of photodiodes for detecting + or - primary light when plural patterns coincide with each other and outputting a correlation signal. The area of a receiving face on the detector 140a is about several or ten times the area of a receiving face on the detector 140b and the centroids of both the detectors 140a, 140b are arranged symmetrically about the focus of the lens 124. The detector 140b having a small area outputs a large detection output at the coincidence of patterns and outputs a small detection output at the discrepancy of patterns. The detector 140b can not easily detect noise because its area is small. On the other hand, the detector 140a having a large area does not change its detection output even when patterns are different. Thereby pattern coincidence having a high SN ratio can be detected by mutually comparing the detection outputs of both the detectors 140a, 140b.

IPC: G03G9/087
Filed: 1984-03-15
Abstract: PURPOSE:To make an amorphous silicon drum hardly stickable with a material which is the cause for generating white spotting or blurring of an image thereon by using a developer contg. a toner at 5-10wt%, more preferably 8-10wt% concn. CONSTITUTION:A thin-layered film is formed by a toner on an amorphous silicon drum. This film has a tendency to be securer as the toner concn. is higher. If the toner concn. is higher, the toner is liable to scatter thus giving rise, on the contrary, to staining the image. Satisfactory prevention of white spotting and blurring is not possible at <5% toner concn. The white spotting and blurring of the image are prevented and the good image free from image staining is obtd. by specifying the toner concn. at 5-10wt%, more preferably 6-8wt% after all.
