An image pickup control device of the present invention drives an image sensor
including an output amplifier. A controller feeds a first control signal to a driver,
which drives the image sensor, for controlling an exposure time. A switching circuit
switches a power supply voltage for driving the output amplifier in accordance
with a second control signal output from the controller and then feeds it to the
output amplifier. The controller feeds the second control signal to the switching
circuit for controlling it in accordance with the exposure time.
