摘要： An image information transmission system that transmits image information, one frame of which is constituted by a plurality of image data. The plurality of pixel data corresponding to the one-frame image information is divided into a plurality of pixel blocks using a predetermined number of pixel data as a unit pixel block. Maximum and minimum values of pixel data within each pixel block are detected in units of divided pixel blocks. Maximum value data representing the detected maximum value and minimum value data representing a detected minimum value are output. One of the different quantization characteristics is selected in accordance with a difference between the maximum and minimum values of each pixel blocks output as described above. A level region between the maximum and minimum values is quantized to obtain a plurality of regions on the basis of the selected quantization characteristic. Position data representing one of the plurality of regions to which the pixel data within the pixel block belongs is output.The maximum and minimum value data output in units of pixel blocks and the position data output in correspondence with the pixel data within each pixel block are transmitted as described above, and therefore, a high-quality image information signal can be transmitted regardless of the characteristics of images.

摘要： When the pixel of interest exists at a pixel position where reference of an error buffer is necessary, a quantization error generated in a region having undergone error diffusion processing is obtained from the error buffer. A quantization error generated in error diffusion processing in a region containing the pixel of interest is obtained from an error memory. Diffusion errors are calculated from the quantization errors using an error diffusion matrix. The value of the pixel of interest and the diffusion errors are added, and the addition value is quantized into the quantization value of the pixel of interest. The difference between the quantization value and the addition value is calculated as a quantization error to be stored in the error memory. When the pixel of interest exists at a pixel position where write in the error buffer is necessary, the quantization error is stored in the error buffer.

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.
