Image processor, image-processing method, and computer-readable medium |
摘要 |
An image processor has: a unit that executes a conversion process on input image data represented by pixels of M grayscales (M≧3), to convert the input data into output image data represented by sub-pixels of two grayscales; and a unit that outputs the output data, wherein the conversion process includes: a process to determine a filling pattern of sub-pixels corresponding to a pixel of interest of the input data according to a corrected grayscale value obtained by adding a correction value to a grayscale value of the pixel of interest; and the pattern includes a core pattern which forms a core of a dot and a growth pattern which grows a dot, the correction value includes a diffused error, and at least a part of the diffused error obtained by weighting an error of a pixel determined as the core pattern is not included in the correction value. |
