Abstract:
1. A pixel processing method for handling a plurality of pixels corresponding to a color filter array to reconstruct missing color components of each pixel originally having a single color component, the method comprising: determining a first difference magnitude according to a difference between a predetermined color component value of a target pixel and a predetermined color component value of at least a surrounding pixel positioned in a first direction, wherein the predetermined color component value of the target pixel and the predetermined color component value of the surrounding pixel positioned in the first direction correspond to different color components, respectively; determining a second difference magnitude according to a difference between the predetermined color component value of the target pixel and a predetermined color component value of at least a surrounding pixel positioned in a second direction, wherein the predetermined color component value of the target pixel and the predetermined color component value of the surrounding pixel positioned in the second direction correspond to different color components, respectively, and an extension of the first direction crosses an extension of the second direction at the target pixel; generating a first determining value according to predetermined color component values of a plurality of pixels positioned in the first direction and the first difference magnitude; generating a second determining value according to predetermined color component values of a plurality of pixels positioned in the second direction and the second difference magnitude; and selecting predetermined color component values of a plurality of specific pixels to compute a target color component value which is a missing component value of the target pixel according to a comparison result of the first and second determining values, and saving the target color component value.
