Abstract
An image pickup apparatus which is capable of setting image quality as desired by a user when performing tone correction according to a luminance histogram of a taken image. A luminance histogram obtaining unit obtains a luminance histogram from image data. A luminance tone correction unit performs tone correction on the image data using a correction curve generated based on the obtained luminance histogram. A user setting unit receives a setting as to a correction intensity of the tone correction from the user and sets parameters for determining coordinate values of control points on the correction curve. A luminance tone control unit generates the correction curve based on the luminance histogram and determines the coordinate value according to the parameters set by the user setting unit.
