IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND IMAGE CAPTURE APPARATUS

摘要

In an image processing apparatus that can provide, to an image, an emphasis effect that serves as a focusing degree indicator, provision of an emphasis effect that is easily distinguished is realized. A signal generation circuit generates signals having values that correspond to the values of process target pixels of image signals. For example, based on the magnitude of a frequency component extracted from the image signals by an extraction circuit, a signal modification circuit applies signals to the process target pixels and outputs the process target pixels. The signal generation circuit generates signals so as to have values that decrease continuously or in a stepwise manner in accordance with increase in the values of the process target pixels.
