QUANTIZATION METHOD, AND RECORDING APPARATUS AND STORAGE MEDIUM USING THE SAME

摘要

When a recording apparatus can perform three gradations expression for each of a low density dot and a high density dot, and can perform recording in five gradations in total for an input data of one pixel in order to obtain a high quality image with no occurrence of a pseudo-contour by a very small load control in expressing a recording pixel in a plurality of gradations, a low density dot and a high density dot are respectively quantized to three-value data in two quantization processing sections respectively for the high density dot and the low density dot, thereby determining a recording level, while not providing five quantization processing sections for determining whether or not a dot is formed for each of the five gradations in recording.
