An imaging system comprising a phase-detection image sensor comprising a plurality of phase-detection pixel units and a processor configured to: interpolate a green image to obtain a full resolution interpolated green image including defocused portions having artifacts and in-focus portions having sharp image, low-pass filter the full resolution interpolated green image to obtain a blurred image of the interpolated green image, combine the full resolution interpolated green image and the blurred image of the full resolution interpolated green image to obtain a corrected full resolution interpolated green image, where the artifacts of the defocused portions of the full resolution interpolated green image are removed, and the sharp image of the in-focus portions of the full resolution interpolated green image is unaffected.
