Abstract
A digital still camera according to the present invention can obtain an image with appropriate brightness easily without an increase in memory capacity. The digital still camera of the present invention includes: an image-capturing unit which captures a field of object to generate an image; a photometry unit which measures a luminance of a predetermined area of the field of object; a calculating unit which calculates a ratio between a luminance value of a portion of the image captured according to the luminance measured by the photometry unit, and a target luminance value of the predetermined area, the portion corresponding to the predetermined area; and a correcting unit which corrects the image generated by the image-capturing unit according to the ratio.
