Abstract:
An imaging circuit, comprising:a storage device for storing control data; an amplifier having a first input coupled for receiving pixel signals that have not been separated by their primary colors, a first output for providing an imaging signal, and a control input coupled to an output of the storage device for receiving the control data to program a gain of the amplifier, where a first value of the control data sets the gain of the amplifier for a first pixel signal and a second value of the control data sets the gain for a second pixel signal to color balance the first and second pixel signals; a first capacitor coupled between the first input and first output of the amplifier; and a first programmable capacitor coupled for sampling the first and second pixel signals at the first input of the amplifier and having a capacitance set by the first value of control data when the first pixel signal is received and by the second value of control data when the second pixel signal is received.
