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 processing apparatus that converts input image data into printable image data is provided. The apparatus performs screen processing on the input image data, and determines whether moiré occurs in screen image data generated by the screen processing unit for a target pixel in the input image data. Depending on the determination result made by the determination unit, the apparatus outputs one of a screen pixel value in the screen image data for the target pixel and a value obtained by converting an input pixel value into a printable pixel value based on intermediate data, as a value of the target pixel in the printable image data, the intermediate data being generated by replacing a screen pixel in the screen image data that is determined to have moiré by the determination unit with the input pixel value in the input image data.
