Abstract
A method for AWB (Automatic White Balance) compensation, performed by a processing unit, the method at least containing acquiring a frame 0; dividing the frame 0 into blocks; obtaining block statistics information of each block of the frame 0; labeling each block of the frame 0 as one type according to its block statistics information; employing a first AWB compensation to the frame 0 with an input of first-type blocks of the frame 0, wherein the first-type blocks of the frame 0 are blocks labeled as a first type; employing a second AWB compensation to a frame 1 with an input of blocks of the frame 1 at the same locations as that of second-type blocks of the frame 0, wherein the second-type blocks of the frame 0 are blocks labeled as a second type; and fusing the compensated frame 0 with the compensated frame 1.
