Abstract:
1. An imaging device comprising: a color component region detection portion that detects, from image data of a photographic subject, a region that has a same or a similar color component to a color component of a target photographic subject; an area calculation portion that calculates an area of the detected region; a luminance calculation portion that calculates luminance of the whole photographic subject and luminance of the detected region; a current luminance level determination portion that determines a current luminance level corresponding to the area of the detected region, using the luminance of the whole photographic subject and the luminance of the detected region; and an exposure amount calculation portion that calculates an amount of exposure such that the current luminance level becomes a target luminance level, wherein when the area of the detected region is equal to or less than a first predetermined area, the current luminance level determination portion determines, in correspondence with the area of the detected region, rations of contribution of the luminance of the whole photographic subject and the luminance of the detected region, respectively, and determines the current luminance level by using the ratios and the luminance of the whole photographic subject and the luminance of the detected region.
