摘要： According to this invention, encoded data are generated by sorting pixel data in a block according to different scan start positions and different scan routes upon generating encoded data for respective blocks, and encoded data with a smallest data amount of these encoded data is outputted. To this end, a block generation unit inputs blocks each defined by 8×8 pixels from image data to be encoded. Four encoding processing units respectively sort inputted 8×8 pixels according to the information stored in scan start position information storage units and scan route information storage units. The respective encoding processing units generate encoded data based on the sorted pixel data. A selector selects and outputs encoded data with a smallest data size from those generated by the encoding processing units.

摘要： Directional data representing a pattern which indicates a growing direction of a dot on a scanning line is generated. Coefficients used to distribute the image data of a pixel of interest are set. An edge of an input image is detected. The image data of the interest pixel of the input image is distributed to the interest pixel and a pixel adjacent to the interest pixel based on the coefficients. Image data distributed from the adjacent pixel is added to image data of the interest pixel on which the distribution is performed, and the sum of the image data is as corrected image data of the interest pixel. The corrected image data and the generated directional data are selected for an edge, and the image data of the interest pixel and input directional data are selected for a non-edge to generate an image signal pulse-width modulated.
