Claims

[Claims for Utility Model Registration] In an image binarization circuit that converts input image data into white and black binary data, two different thresholds are used to convert white areas, black areas, or gray areas of the input image data. an area determining means for determining, and based on the determination result of the area determining means, generating white or black binary data in which white and black pixels in the gray area are arranged corresponding to pixel positions of the input image data. An image binarization circuit comprising: an output means for outputting the image.
