  • Compressing and restoring method of image data including a free microdot image element, a print dot image element, and a line picture image element
    Patent number: 7813572
    Abstract: A method for compressing/restoring image data free from degradation of image quality caused by compression/decompression, a method for compressing image data at high compression ratio, and its restoring method are disclosed. In the image data compressing method, image elements contained in a digital image read from a sheet of paper are extracted, each of the extracted image elements is subjected to data compression by a compression method of corresponding to the type of the image element, and the compressed image element data are stored.
    Type: Grant
