The present invention provides a method for rotating YUV4:2:0 image in a digital display device, such as TV image system. A YUV4:2:0 image is separated to a Y division matrix and a U and V division matrix. Then the Y division is performed a rotation matrix calculation. And the U and V division matrix is performed a reverse rotation matrix calculation. A rotated YUV4:2:0 image is obtained by combining the processed Y division matrix and the processed U and V division matrix.
