Abstract
A first intermediate image generating means () generates an intermediate image (D) by extracting a component of an input image DIN in a particular frequency band; a second intermediate image generating means () generates an intermediate image Dhaving a frequency component higher than the intermediate image (D); a first intermediate image processing means (M) generates an intermediate image (DM) by amplifying the pixel values in the intermediate image (D); a second intermediate image processing means (H) generates an intermediate image (DH) by amplifying the pixel values in the intermediate image (D); and an adding means () adds the input image (DIN) and the intermediate image (DM) and the intermediate image (DH) together to obtain an output image (DOUT). A first amplification factor (DMA) and a second amplification factor (DHA) are determined according to pixel values in the input image (DIN). Even if the input image includes a fold-over component on the high-frequency side or does not include an adequate high-frequency component, an enhanced image can be provided without causing overshoot.
