Description

In a typical image-binaization process, first, an original analog image is converted to the high-resolution digitized image by consuming time and hardware resources for serial scan and 6-8 bits A/D converting every pixel, then, it is converted to the binary image by digital processing. The process seems to be unefficient. This paper describes an analog circuit carrying out binarization process based on least squares criteria. The circuit is integrated on single chip with photosensors in order to directly convert an original analog image to the binary image. The process can overcome an image-reading bottleneck for high-speed image processing.
