Abstract:
1. An image pick up control device for driving an image sensor comprising: a photosensitive section in which a plurality of photosensitive devices are arranged for generating signal charges corresponding to incident light; a plurality of vertical transfer paths for vertically transferring said signal charges; a horizontal transfer path for horizontally transferring said signal charges transferred from said plurality of vertical transfer paths; an outputting circuit for detecting said signal charges transferred from said horizontal transfer path and outputting electric signals corresponding to said signal charges; a driver for driving said image sensor; a controller for feeding a first control signal to said driver to thereby control an exposure time over which said image sensor generates the signal charges; and a switching circuit for switching a power supply voltage for driving said outputting circuit in accordance with a second control signal and then feeding said power supply voltage to said outputting circuit; said driver comprising a signal generating circuit for generating timing signals for causing said image sensor to transfer the signal charges, which are generated over the exposure time, to said outputting circuit via said plurality of vertical transfer paths and said horizontal transfer path; said controller feeding said second control signal to said switching circuit for controlling said switching circuit in accordance with the exposure time; said controller determining the exposure time in accordance with an exposure value for shooting a desired scene and feeding said second control signal to said switching circuit at a timing matching with said exposure time to thereby cause said switching circuit to drive said outputting circuit at a low voltage.
