An image processing apparatus which enables natural edge enchantment suited to a frequency band of a subject even when performing local contrast correction in combination with edge enhancement. A local contrast correction unit multiplies a signal of a target pixel in image data by a gain based on values obtained by reflecting signals of pixels around the target pixels.

An edge signal is extracted from the image data and multiplied by a gain based on a signal output from the local contrast correction unit. The edge signal is added to a signal output from the gamma conversion unit.
