  • Patent number: 5081535
    Abstract: In an electronic still camera, an aperture plate having a number of different apertures and shading portions is provided. When picking up an image, one of the apertures that is selected depending on a light measurement value is inserted in an exposure light path to start exposure of a solid state imaging device simultaneously with the start of a charge storage time thereof. After the charge storage time, the aperture plate is moved by a driving device to insert one of the shading portions in the exposure light path in place of the aperture so as to shade the solid state imaging device.
