Filed: 1983-03-31
Abstract: PURPOSE:To perform identification process at an extremely high speed and to perform automatic identification of automobiles effectively, by determining the registered numbers of the automobiles at a constant distance by a TV camera all the time. CONSTITUTION:The registered numbers of automobiles are detected by using a TV camera. As for a position where the TV camera is placed, the position, where the vehicle is once stopped or goes slowly, such as, e.g., a toll station of a speed way or an intersection is suitable. The DC component of a picture signal obtained by the TV camera is cut in a filter circuit (c) in order to extract bright and dark data, which are the features of the picture. Then the signal is sliced in a comparator (d) at a specified level. Thus binary coding is performed. The binary-coded picture signal is decomposed into many picture element signals. Picture element shift registers (b) in the number of stages corresponding to a picture element number N for one scanning line are arranged in parallel in multiple stages by a number M of the scanning lines occupying one character of the registered number in the longitudinal direction in one screen. The signals of the picture elements obtained from the binary coded picture signal of each scanning line are sequentially stored in the registers.

Title: Image processor
Inventor: HASHIMOTO YASUNORI
IPC: H04N1/40
Filed: 1988-03-11
Abstract: PURPOSE:To discriminate a halftone area from a binarized area clearly, by a method wherein, when a read image consisting of a binarized area and a halftone area is processed, the read image is directly separated into the binarized area and the halftone area before the characteristic correction for an output image is added. CONSTITUTION:When an original mode is a mixed mode, a read image signal is converted to a digital signal by an A/D conversion part 6, furthermore being characteristic-corrected by a characteristic correction part 7. After that, an image area separation part 13 identifies per pixel whether the pixel is in a character area or in a picture area, and the result is inputted to a multiplexer 14. Namely, in the multiplexer 14, an image signal is inputted from a simply binarizing part 11 if the identification results in a character area, or, for example, from a dither processing part 12 if it results in a picture area, and the inputted image signal is outputted to a multiplexer 15 as it is. In addition, the dither processing part 12 inputs the image signal from an image correction part 9 and outputs the image signal binarized according to linear input/output characteristics. In this manner, an image quality in a picture area in printing can be enhanced.
