Abstract:
In one embodiment, a camera is provided that includes: an image sensor configured to provide an image signal; an automatic gain control (AGC) unit configured to determine an AGC control signal for controlling a gain applied to the image signal; a cooler configured to cool the image sensor; and a thermal control circuit configured to compare the AGC control signal to a threshold, wherein the thermal control circuit is further configured to turn on the cooler if the comparison indicates that the AGC control signal exceeds the threshold.
