Abstract
An electronic camera includes: an image-capturing unit with variable image-capturing sensitivity, which captures an image of a subject through a photographic lens; a brightness detection unit that detects subject brightness; an exposure calculation unit that executes an exposure calculation by using, at least, the image-capturing sensitivity set at the image-capturing unit and the subject brightness having been detected; a flash quantity calculation unit that calculates a main flash quantity for a flash unit that illuminates the subject when capturing an image thereof; and a sensitivity adjusting unit that adjusts the image-capturing sensitivity so as to achieve optimal exposure with a main flash quantity within a flash quantity control range of the flash unit when the main flash quantity having been calculated by the flash quantity calculation unit is outside the flash quantity control range. And if the image-capturing sensitivity has been adjusted by the sensitivity adjusting unit, the exposure calculation unit re-executes the exposure calculation.
