The present invention relates to an image processing device for converting the number of pixels or scanning lines. In particular, the image processing device according to the present invention comprises an operator for carrying out interpolation operations and a memory for storing filter coefficient sets utilized in the interpolation operations. The memory stores filter coefficient sets each corresponding to each of the phases when the pixel interval of the original image is divided by a prescribed dividing number. Out of these filter coefficient sets, a filter coefficient set that corresponds to the phase closest to that of the pixel data to undergo interpolation operations is then outputted to the operator. The operator then carries out interpolation operations on the pixel data using these filter coefficient sets so that arbitrary format conversion becomes possible.
