Abstract
A CPU determines whether or not a picked up image that corresponds to image data is a backlit portrait image by analyzing the image data on a pixel-by-pixel basis, and if the picked up image that corresponds to the image data is determined to be a backlit portrait image, then executes a brightness correction for backlit portrait image. The CPU obtains a tone curve that may have an output value of a predetermined value FV as an output value in response to an input value of a flesh-colored pixel average luminance value PV ave, which is an average luminance value of flesh-colored pixels of all pixels that constitute the image data. The CPU applies the tone curve to the luminance of every pixel in the image data and thereby executes the brightness correction.
