PROBLEM TO BE SOLVED: To obtain proper exposure even in a state where a high-luminance area is dispersed to the entire field such as when photographing sunbeams shining through branches of trees. SOLUTION: The camera includes an image sensor, and a plurality of photometry areas are assigned to the field caught by the image sensor. A CPU evaluates the luminance of the field for every photometry area (S21), and binarizes each of a plurality of luminance evaluated values obtained by evaluation processing (S23). The extent of the high-luminance area included in the field is calculated based on the plurality of binarized luminance evaluated values (S25), while the extent of an adjacent area adjacent to the high-luminance area out of a low-luminance area included in the field is calculated (S27 and S29). Each of the plurality of luminance evaluated values obtained by the evaluation processing is corrected based on the ratio of the calculated extent of the adjacent area to the calculated extent of the high-luminance area (S35 to S39). The exposure for the image sensor is adjusted based on the luminance evaluated value thus corrected. COPYRIGHT: (C)2009,JPO&INPIT
