Abstract
A temperature compensating circuit for a Charge Coupled Photodiode array ch monitors a composite video output signal from a video processor and generates an error signal proportional to the square wave resulting from an unbalanced condition. The error signal is used to generate bias voltages which are applied to the Charge Coupled Photodiode array and a degenerative feedback loop is formed which nulls the error signal and automatically balances the array odd and even video outputs.
