<p>A driving apparatus (11) for solid state image sensors used for an electronic still camera for taking a still picture with a solid state image sensor, and adapted to generate timing pulses for carrying out an exposure operation of the solid state image sensor (1) and reading electric charges occurring in a light receiving portion of the solid state image sensor (1) due to the exposure of the film. A device (13) generates timing pulses for carrying out the exposure and reading operations of the solid state image sensor (1). A sweeping action controller (32) in the timing pulse generating device (13) makes when a predetermined voltage is applied from the outside thereto a timing pulse for sweeping the electric charges, which are accumulated in the light receiving element (45) in the solid state image sensor (1), to the outside. The predetermined voltage is applied to the sweeping action controller (32) before the starting of the exposure operation to carry out an operation of sweeping out the electric charges in the solid state image sensor (1).</p> |
