Patent ID: 7161602

Claim:
A pixel interpolation method for generating a pixel value of a target pixel in a frame, the pixel interpolation method comprising: utilizing a plurality of pixel pairs of two successive scan lines to determine at least one first possible edge angle associated with the target pixel, wherein one scan line of the two successive scan lines is above the target pixel and the other scan line of the two successive scan lines is under the target pixel; utilizing a plurality of pixel distribution trends of the two successive scan lines to determine at least one second possible edge angle associated with the target pixel; determining a most appropriate edge angle according to said at least one first possible edge angle and said at least one second possible edge angle; and interpolating the pixel value of the target pixel utilizing a first pixel and a second pixel associated with the appropriate edge angle and the target pixel and respectively located on the two successive scan lines, wherein the first pixel and the second pixel reside on different scan lines located on different sides of the target pixel.
