Abstract
A system which operates to determine temperature of an image sensor using the same signal chain that is used to detect the image sensor actual outputs. A correlated double sampling circuit is used to obtain the image outputs. That's same correlated double sampling circuit is used to receive two different inputs from the temperature circuit, and to subtract one from the other. The temperature output can be perceived, for example, once each frame.
