{HEAD ~ 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 an observing pixel on an interpolation axis parallel to X axis or Y axis and {TAIL ~ a second pixel} as a corresponding pixel on the same interpolation axis, based on the pixel data on the first and second sweep lines
