Abstract: Dot characteristic points are first extracted from M-level image data by the dot characteristic point extracting device. A dot area identifying device subsequently identifies a dot area based on the results of the extraction carried out by the dot characteristic point extracting device. When the image attribute determination is completed, a parameter setting unit sets N-level conversion parameters based on the results of the determination carried out by the dot area identifying device. Consequently, N-level conversion takes place using the N-level conversion parameters appropriate for a dot area. Therefore, N-level conversion in which the occurrence of moire is prevented may be carried out regarding dot areas.

Abstract: The method and apparatus particularly adapted for reducing the storage capacity of line memories needed for temporarily storing image data for lines until image data for the last line is obtained in digital filtering. Inputted image data are divided into a plurality of blocks, each of which consists of image data obtained from n pixels. The integer n may assume a value of 8, 16, 32, etc. The constituents of one block after another are compressed such that image data consisting of 8 bits per pixel are converted into encoded data consisting of 2 bits per pixel. Data on a dynamic range and an average value for each block are added as a headder to the encoded data. Compressed image data are taken out of a buffer memory after being temporarily stored therein and, together with or separately from compressed image data newly outputted from a compression unit, subjected to image processing such as MTF correction in an arithmetic unit.

Abstract: Image compression is accomplished by dividing an image into blocks which are encoded and compressed by finding similarities among the blocks. Image quality and speed are increased through several mechanisms such as varying the size of the blocks when image edges or test is present, by comparing the image blocks to prestored image patterns rather than other portions of the image, using raw data rather than compressed data under certain conditions and the use of inspection areas to increase the possibility of finding the most similar area quickly.
