PURPOSE:To allow one-shot image pickup operation by providing a shutter for inhibiting light incidence to an image pickup element during a charge transfer period in still mode, and then suppressing the generation of a smear and stopping sampling in accompanied with a switching to still mode. CONSTITUTION:An image pickup device is provided with an aperture means AP for measuring object luminance and an optical system provided with a shutter means SHT, storage time setting circuit SE1, storage time indication setting circuit SE2, aperture value setting circuit SE3, etc. Outputs of those respective circuits SE1-SE3 and the output of a light metering means are processed by an arithmetic circuit OP and on the basis of the arithmetic result, an ammeter AM for the means AP and a magnet Mg for the SHT are controlled to control the quantity of light mode incident to the device. Further, successive and still mode switches SW1 and SW2 are provided to switch scans of the image pickup means, and to switch exposure parameters to be inputted to the circuit OP through gates G4 and G5. Then, an AND circuit stops the holding of a sample holding circuit SHC. |
