In a method for sampling image data from an image frame with component video, the image frame includes a first component frame, a second component frame and a third component frame. The method comprises steps of selecting a first component portion, a second component portion and a third component portion from the first component frame, the second component frame and the third component frame, respectively; and operating the first component portion, the second component portion and the third component portion to obtain a sampled unit arranged as a block array. The sampled unit includes at least a first component blocks derived from the first component portion, a second component block derived from the second component portion and a third component block derived from the third component portion.
