The device includes a module for converting the first and second pixel data into data in the XY coordinate system, a module for generating pixel data of an interpolation target pixel located between a first pixel as {HEAD ~ an observing pixel} on an interpolation axis parallel to X axis or Y axis and a second pixel as a corresponding pixel on the same interpolation axis, based on the pixel data on {TAIL ~ the first and second sweep lines}
