ABSTRACT:
In a color imaging apparatus having a single chip solid state state sensor and an n color filter matrix, n color signals are used by an operation circuit in a first signal processing mode to generate chrominance signals and a luminance signal. When one of the n color signals reaches a saturation level, the operation circuit utilizes the remaining n-1 color signals. When a second color signal reaches the saturation level, a compensation signal is generated from a particular non-saturated color signal and the operation circuit utilizes the remaining n-2 non-saturated signals, including the particular non-saturated signal, and the compensation signal to produce the chrominance signals and the luminance signal. Compensation signals are generated from the particular signal until the particular color signal saturates. The particular color signal saturates last.
