  • Publication number: 20100020198
    Abstract: Disclosed is a digital still camera in which amount of exposure is decided appropriately even when there is a changeover from one shooting scene to another. When a shooting mode is set, a first shooting scene discrimination is performed before a shutter-release button is half-pushed. A first amount of exposure is calculated using a program diagram suited to the shooting scene that has been discriminated by the first shooting scene discrimination. Shooting for focusing control is performed at an exposure corresponding to the first amount of exposure, whereby image data is obtained. Focusing control is carried out based upon the image data obtained, and shooting is performed again. Second shooting scene discrimination is performed based upon the image data obtained by shooting. A second amount of exposure is calculated using a program diagram suited to the shooting scene that has been discriminated by the second shooting scene discrimination.
