Abstract:
1. An image processing apparatus which determines a scene of a captured image, the apparatus comprising: a first light metering unit configured to divide a screen of the captured image into a plurality of photometry areas and perform light metering; a second light metering unit configured to divide a screen of the captured image into one portion and a peripheral portion thereof and perform light metering; a distribution detection unit configured to detect whether a luminance distribution on the screen changes to a hill-shaped form, based on a result of adding photometric values of each of the photometry areas acquired by the first light metering unit by rows and by columns; a difference calculation unit configured to calculate a luminance value difference between the one portion and the peripheral portion thereof acquired by the second light metering unit; a ratio calculation unit configured to calculate a ratio of pixels having a luminance value higher than or equal to a threshold value in the one portion measured by the second light metering unit; and a spotlight determination unit configured to determine whether a scene of the captured image is a spotlight scene according to a detection result of the distribution detection unit, calculation result of the difference calculation unit, and a calculation result of the ratio calculation unit.
