Abstract:
1. An apparatus for recognizing a gray scale image, comprising: inputting means for inputting a gray scale image; and multi-code image binary-coding means for converting the inputted gray scale image to a binary image by determining whether each pixel corresponds to a background area or a plotting area and producing binary values in which each pixel has a value representing either a background area or a plotting area in the gray scale image, said multi-code image binary-coding means comprising: partial area extracting means for one or more partial areas in the gray scale image, partial image binary-coding means for executing a binary-coding process for each of the partial areas of the gray scale image and extracting a partial binary image, and binary image combining means for combining the one or more partial binary images and for constituting the binary image of the entire scale image.
