PROBLEM TO BE SOLVED: To provide a method to improve precision of detection of a motion vector for image processing in a display device that carries out image processing. SOLUTION: A motion vector 8 generated in a motion vector detection circuit 3 from an image from which noise of an input image signal S1 is eliminated in a noise removal circuit 1, and a motion vector 9 generated in a motion vector detection circuit 4 from an image from which noise of the image signal S1 is eliminated in a noise removal circuit 2 of a system different from the noise removal circuit 1 are inputted in a motion vector selection circuit 5. In the motion rector slection circuit 5, by adopting a vector present in both the motion vector 8 and the motion vector 9 and outputting it as a motion vector 10, erroneous detection of vectors due to noise can be reduced and the precision of the motion vector can be improved. This motion vector is used for image processing in an image processing circuit 7. COPYRIGHT: (C)2006,JPO&NCIPI |
