发明名称 IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
摘要 An image processing apparatus includes 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 divided photometry areas by rows and by columns, a difference calculation unit configured to calculate a luminance value difference between one portion of the screen and the peripheral portion thereof, a ratio calculating unit configured to calculate a ratio of pixels having a luminance value higher than or equal to a threshold value in the one portion, 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.
