ABSTRACT:
A line image which comprises one line parallel to the juxtaposing direction of light-emitting elements is extracted from a three-time image, and a work region is determined, in which, in the juxtaposing direction, an M sub-pixel is added to the front side of the line image and an N sub-pixel is added to the rear side thereof. A background image of a region corresponding to the work region is read out from the frame memory. The read out background image whose precision is made the same as that of the three-time image in a pseudo state, and the line image are blended to obtain a blend image. Image data resulting from the blend image are written in a region corresponding to the work region of the frame memory. The above process is repeated for all lines of the three-time image.
