Abstract: An image processing method includes: analyzing, by a white balance gain estimation circuit, a plurality of exposure frames with different exposures to generate a plurality of sets of white balance gain settings; combining the plurality of sets of white balance gain settings to generate a white balance gain table; applying the white balance gain table to the plurality of exposure frames to generate a plurality of white balance compensated frames; and generating a high dynamic range (HDR) frame by performing pixel fusion according to pixel data derived from the plurality of white balance compensated frames.
