<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus or the like, capable of preventing degrading of image quality at switching of data buffers. <P>SOLUTION: The image processing apparatus includes a first halftone processing means 110 for applying half-tone processing to each of partial image data by using the error diffusion method; a second half-tone processing means 120 for applying error calculation half-tone processing to a tip part of each of the partial image data prior to the first half-tone processing; two error buffers 35a, 35b for storing errors by the first half-tone processing in succession to earlier errors by the second half-tone processing, and two data buffers 36a, 36b for storing processing results by the first half-tone processing, and the first half-tone processing means uses the errors stored earlier in the two error buffers, to start half-tone processings of the partial image data. <P>COPYRIGHT: (C)2007,JPO&INPIT |
