A digital refocusing method is provided. The digital refocusing method includes: obtaining multiple images correspond to multiple views of a scene, wherein multiple images includes a central view images and at least one non-central view image; performing a pixel shift to the non-central view image; performing a line-scan procedure for obtaining corresponding pixels of the central view image and corresponding pixels of the non-central view image; performing view interpolation for obtaining target pixels of novel views in accordance with a target disparity, thereby constructing a refocusing image from the novel views by the target pixels.
