An activity-based system for, and method of, reducing Gr-Gb gain imbalance and a digital camera incorporating the system or the method. In one embodiment, the system includes: (1) a sensor configured to provide a input Bayer pattern array containing amplitudes corresponding to Gr and Gb cells and (2) a processor coupled to the sensor and configured to (2a) compute for at least some of the Gr and Gb cells: activity measures for pluralities of adjacent, same-type cells, green precompensation factors based on the activity measures, averages for the pluralities of adjacent, same-type cells and averages for pluralities of adjacent, opposite-type cells and (2b) use the green precompensation factors, the averages for the pluralities of adjacent, same-type cells and the averages for the pluralities of adjacent, opposite-type cells to form an output Bayer pattern in which the Gr-Gb gain imbalance is reduced.
