Abstract
An image data interpolation apparatus includes an image data obtaining unit for obtaining image data representing an image as dot-matrix picture elements, a picture element interpolating unit capable of selectively executing one of a plurality of interpolating processes when the image data is interpolated so that the number of constituent picture elements thereof is increased, a feature amount obtaining unit for obtaining a feature amount concerning the image data with respect to the selected interpolating process, and an interpolating process selecting unit for selecting one of the interpolating processes capable of obtaining an optimum result of interpolation according to the feature amount obtained by the feature amount obtaining unit and causing the picture element interpolating unit to execute the selected interpolating process.
