1. A pixel processing method, comprising: selecting a first plurality of color component values of a first plurality of pixels within a pixel block of a buffering device, and performing a first color component process upon a first target pixel in the first plurality of pixels to determine a first target color component value of the first target pixel, and storing the first target color component value; while the first color component process is being performed, simultaneously selecting a second plurality of color component values of a second plurality of pixels within the pixel block and performing a second color component process upon a second target pixel in the second plurality of pixels according to the second plurality of color component values to determine at least one underdetermined target color component value of the second target pixel, wherein the second target pixel has been processed by the first color component process; and loading a specific pixel within the pixel block of the buffering device; wherein the first color component process is determined according to a pixel feature of the specific pixel, and the first color component process comprises one of the following steps: (a) balancing the first target color component value of the first target pixel according to a second portion of color component values of the first plurality of color component values; and (b) configuring a predetermined color component value of the first target pixel as the first target color component value; (c) interpolating the first target color component value of the first target pixel according to a first portion of color component values of the first plurality of color component values; wherein when the specific pixel corresponds to a red (R) color component or a blue (B) color component, the first color component process is step (c); when the specific pixel corresponds to a green (G) color component and an adjacent pixel of the specific pixel, adjacent in the same row, corresponds to the B color component, the first color component process is step (a); and when the specific pixel corresponds to the G color component and the adjacent pixel of the specific pixel corresponds to the R color component, the first color component process is step (b).
