Patent ID: 8295697

Claim:
A camera capable of performing at least one of moving image shooting and live view displaying, the camera comprising: a photographing unit for converting an image formed by a shooting lens into an electric signal; a subject brightness obtaining unit for obtaining a subject brightness; an exposure computing unit for computing a shutter speed and an aperture value on the basis of the subject brightness obtained by the subject brightness obtaining unit; a shutter for controlling, on the basis of the shutter speed output by the exposure computing unit, a time period in which the photographing unit accumulates the electric signal; and an aperture control unit for controlling, on the basis of the aperture value output by the exposure computing unit, an aperture value of an aperture unit that limits a quantity of light incident from the shooting lens, wherein the exposure computing unit calculates a deviation between a previous exposure amount and a proper exposure amount on the basis of brightness information relating to a previous exposure and output by the subject brightness obtaining unit, the aperture value of the aperture unit, and the shutter speed of the shutter, and computes an aperture value of the aperture unit for a subsequent exposure on the basis of the deviation.
