摘要: A texture which is not normally generated by a pseudo halftone process is artificially generated by combining quantization values (S307, S308), and a 1-bit code is expressed by the presence/absence of texture.

摘要: An image processing apparatus includes a window setting unit which sets a window for input low-resolution information, including a target pixel and pixels surrounding the target pixel. A detection unit detects MAX and MIN values from among the pixels within the window, and a quantization unit quantizes information relating to each pixel, having n values within the window, into a value smaller than n. A LUT (look-up table) determines a distribution ratio of the MAX and MIN values based on quantized values provided by the quantization unit within the window. A transformation unit synthesizes the MAX and MIN values based on the distribution ratio, and a forming unit forms high-resolution output information from the synthesized values. Thus, input low-resolution information is converted into high-resolution output information, at a high speed, to produce a high quality image.

摘要: An image encoding apparatus of this invention extracts a character/line image from a multi-value image, and substitutes image information corresponding to the extracted character/line image with substitution data based on the image information. Thereafter, the apparatus encodes the image information corresponding to the character/line image, and the remaining image information by different methods, thereby performing efficient image encoding while preserving quality of a character/line image in a multi-value image.
