    摘要: An image encoding apparatus generate encoded data having a fixed length L which is less than or equal to m×n bits and an integral multiple of 32 by m×n pixel block, while resolution information and color information are excellently maintained. For this purpose, a block generation unit inputs image data by m×n pixels. A 2-color extraction unit extracts representative colors C0 and C1 from the input block image data. An identification information detection unit generates m×n items of identification information each identifying each pixel in the block as a pixel approximate to one of the colors C0 and C1. An identification information deletion unit deletes the items of identification information in corresponding positions based on a deletion pattern stored in a deletion pattern memory. A packing unit packs the colors C0, C1 and the identification information after deletion, and outputs the data as encoded data.

    摘要: This invention scans a block using a window having a size of p×q pixels, and encodes p×q sub-block data each formed from pixel data at relatively identical positions in windows. A blocking unit receives a 16×16-pixel block image. A sub-block division unit scans the received block for each 2×2-pixel window, and generates 2×2 sub-block data each having a size of 8×8 pixels. Each sub-block is formed from pixel data at relatively identical positions in windows. A variable length coding unit encodes each sub-block data. When the sum of encoded sub-block data exceeds an allowable encoded data amount, a sub-block elimination unit eliminates encoded sub-block data until the sum becomes equal to or smaller than the allowable encoded data amount. The sub-block elimination unit outputs the remaining encoded sub-block data as encoded data of a block of interest.

    摘要: An apparatus and method encodes into block units an image in which halftone images and character and/or line images are mixed, and makes a substitution value, substituting for pixels in which pixels of a character and/or line image exist, a value whereby the occurrence of quantization errors of direct current components after frequency conversion is substantially zero, thereby minimizing block distortion of images when decoding. Therefore, a blocking unit inputs images in 8×8 pixel blocks. An acquisition unit acquires pixel data of character and/or line images as acquisition color information and acquires identification information identifying character and/or line image pixel positions. A substitution unit substitutes pixel data acquired as character and/or line images in image data of input blocks with a substitution value determined based on pixel data having halftone attributes.

    摘要: An image processing apparatus performs conversion and a first compression on upper bits in image data, thereby generating a first compressed data set, and performs a second compression on lower bits in the image data, thereby generating second compressed data. The image processing apparatus then performs a first decompression on the first compressed data set, thereby generating a first uncompressed data set, and performs a second decompression on the second compressed data, thereby generating second uncompressed data. Finally, the image processing apparatus interpolates the first uncompressed data set based on the second uncompressed data.
