Abstract
An image expansion apparatus includes a second order differential circuit, a multi-valued processing unit, a first determination unit, a selection unit, and an interpolation processing unit. The first determination unit compares respectively a plurality of fixed patterns, which is each assigned with an interpolation direction in accordance with an outline shape of an image, with spatial dispersion of an output of the multi-valued processing unit. The first determination unit determines a fixed pattern corresponding to the output. The first determination unit determines an interpolation direction assigned to the fixed pattern as a candidate of an interpolation direction for the outline shape. The selection unit selects an interpolation direction of a plurality of candidates of the interpolation direction for the outline shape. The interpolation processing unit generates an interpolation pixel to determine the pixel for the interpolation based on the interpolation direction selected by the selection unit.
