Abstract: <P>PROBLEM TO BE SOLVED: To meet a challenge in which further speedup of processing is desired for converting image data by an error diffusion method.  <P>SOLUTION: It is judged whether or not a noted block satisfies prescribed block processing requirements on the basis of a gradation value of each pixel in the noted block for converting the image data. If it is judged that the block satisfies the requirements, the image data of the pixels in the noted block are collectively converted while diffusing gradation errors of the entire noted block into non-conversion pixels in another block. Even if it is judged that the block does not satisfy the requirements, it is judged whether or not dots are formed in the noted block. If it is judged that the dots are not formed, the image data of the pixels in the noted block are collectively converted while diffusing the gradation errors of the entire noted block into non-conversion pixels in another block. In this way, conversion processing for the image data by the error diffusion method can be further accelerated while keeping high image quality.  <P>COPYRIGHT: (C)2003,JPO
