Imaging apparatus, image processing apparatus, and program

An imaging apparatus comprising:

• determination means for determining whether a capture image is a frontlit image;
• detecting means for detecting a flesh-color area in the capture image;
• and
• when the capture image is determined to be a frontlit image, correction means for correcting brightness of the capture image such that a high-luminance area having a relatively high luminance value comes closer to a correct luminance value than a low-luminance area having a relatively low luminance value among the flesh-color area.

An image processing apparatus comprising:

• determination means for determining whether a capture image is a frontlit image or a backlit image;
• detecting means for detecting a flesh-color area in the capture image;
• calculation means for setting weights, in a luminance histogram on the flesh-color area, on luminance of pixels included in a high-luminance area having a relatively high luminance value and luminance of pixels included in a low-luminance area having a relatively low luminance value in accordance with the determination result, and calculating modified luminance produced by modifying luminance on the flesh-color area on the basis of the weights;
• and
• correcting means for correcting brightness of the capture image on the basis of the modified luminance.
