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.

Abstract: An image capture method for flash photography includes: capturing at least one first image while a strobe device is operating under a first strobe intensity setting for emitting main flash, capturing at least one second image while the strobe device is operating under a second strobe intensity setting different from the first strobe intensity setting, and generating an output image by blending the at least one first image and the at least one second image.
