Abstract:
Method, apparatus and system for determining a value for green-green imbalance and applying the value to green pixels to correct the imbalance are described. Average pixel values of green pixels within a kernel are calculated and an imbalance value is determined based on the averages. The imbalance value is added to or subtracted from all green pixel response values in the kernel to correct the imbalance.
