1. An electronic device comprising:
at least one processor configured to:
estimate green values at red and blue pixel locations of an input Bayer frame based on green values at green pixel locations of the input Bayer frame; and
generate red, green, and blue channels of joint demosaiced-warped output RGB pixels from the input Bayer frame based on the green values at the green pixel locations, the estimated green values at the red and blue pixel locations, an alignment vector map, and kernels for red, green, and blue pixels.
