Abstract
A judgment is made as to whether an interpolation point in an original image is or is not located at an image edge portion. The judgment is made by using a threshold value having been set such that, as a desired level of sharpness of an interpolation image obtained from interpolation processing becomes low, the threshold value may become large. When an interpolation point is judged as being located at an image edge portion, an interpolated image signal component corresponding to the interpolation point is calculated with interpolation processing capable of keeping the image edge portion sharp. When an interpolation point is judged as not being located at an image edge portion, an interpolated image signal component corresponding to the interpolation point is calculated with the interpolation processing, which is carried out by combining interpolation processing for obtaining an interpolation image, which has a comparatively high sharpness, and interpolation processing for obtaining an interpolation image, which has a low sharpness.
