Abstract
An image processing apparatus receives an input image signal and performs an enhancement process on a high frequency component included in the input image signal based on a low frequency component of the input image signal. The apparatus extracts a low frequency component from the input image signal and combines a step variation component of the input image signal with the low frequency component to generate a combined wave component. The apparatus performs an enhancement process on the high frequency component obtained by removing the combined wave component from the input image signal.
