摘要： An image processing method includes the steps of: obtaining image data formed by signals of a plurality of pixels expressing a color image; discriminating a photographic scene of an image from the image data; determining a gradation correction method based on a result of discriminating a photographic scene; determining a first gradation correction amount based on a result of discriminating a photographic scene; detecting a face area in an image of the image data and calculating a face detection reliability; determining a second gradation correction amount based on an average luminance of the face area; determining a third gradation correction amount by weighted averaging the first gradation correction amount and the second gradation correction amount based on the face detection reliability; and applying a gradation correction process to the image data by using the third gradation correction amount and the gradation method.
