A circuit and method color balance pixel signals (V ) on-the-fly in an image capturing system ( ). The pixel signals are amplified in a programmable gain amplifier ( ) whose gain is set by the ratio of a programmable capacitor ( ) to a fixed capacitor ( ). Control data (CONTROL) sets the capacitance of the programmable capacitor by enabling switches ( ) that enable binary weighted capacitors ( ). The control data adjusts the gain of the programmable amplifier as each pixel signal is applied, so that the pixel signals of all primary colors are amplified in the same programmable gain amplifier.
