发明名称 Image processing apparatus and image processing method
摘要 An image processing apparatus and an image processing method that enable suitable contrast adjustment are provided. The image processing apparatus includes region detection means configured to detect (S215) predetermined first luminance level detection region and second luminance level detection region in a human face as a target to be photographed, luminance amount calculation means configured to calculate (S221, S225) an absolute value of a difference between a luminance level of the first luminance level detection region and a certain reference luminance level as a high luminance amount and calculate (S223, S225) an absolute value of a difference between a luminance level of the second luminance level detection region and the reference luminance level as a low luminance amount, and determination means configured to determine (S241) whether a difference or a ratio between the high luminance amount and the low luminance amount falls within a certain range.
