Abstract:
The image processing apparatus executes a zoom process to an image data depending on a received zoom level, selects a dither matrix from a plurality of dither matrices each having a different resolution. The image processing apparatus selects a dither matrix that has a higher resolution in a case that the received zoom level is equal or less than a first zoom level to reduce the image data. Furthermore, the image processing apparatus selects a dither matrix that has a lower resolution in a case that the received zoom level is equal or more than a second zoom level to enlarge the image data.
