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 the image-capturing sensitivity set at the image-capturing unit and the detected subject brightness; 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 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.

Abstract: A subject tracking apparatus includes a light detector, a focus detector, and a tracking controller. The focus detector is configured to detect focus information at a plurality of focus detection regions in a view of an image. The focus information includes at least focus information detected at a subject region of a subject in the view. The tracking controller is configured to determine at least one first region having substantially same light information as light information detected at the subject region from among a plurality of light measurement regions, to determine at least one second region having substantially same focus information as the focus information detected at the subject region from among the plurality of focus detection regions, and to determine reference information for tracking the subject in the view based on the at least one first region and the at least one second region.

Abstract: An electronic apparatus includes a detection unit that detects eyes from an image, a selection unit that selects one eye from the eyes detected by the detection unit, an operation unit that accepts an operation of causing the selection unit to select an eye different from the selected eye, and a display unit that displays an indication superimposed on an image indicating that the eye is selected by the selection unit.
