Abstract: PURPOSE: A repeated pattern judging method, a frame interpolation method using the same and an apparatus suitable for the same are provided to discriminate that a repeated pattern moves between frames. CONSTITUTION: An MAE(Mean Ratio Error) calculating unit(1202) obtains MAEs with respect to respective reference blocks, which exist in a search range with an (M+2P)x(N+2P) size of a frame which refers for searching a reference block and a motion vector, by a full search method. An MAE map storing unit(1204) stores (M+P)x(N+P) MAEs as a map type with an (M+P)x(N+P) size. A motion vector extracting unit(1206) judges positions(x,y) of horizontal and vertical directions of a reference block having the least MAE among the MAEs stored in the MAE map storing unit(1204) as an interframe motion direction with respect to a current block. A repeated pattern recognizing unit(1210) discriminates whether a repeated pattern exists with reference to the MAEs stored in the MAE map storing unit(1204). A frame interpolation unit(1212) performs frame interpolation using a motion vector extracted in the motion vector extracting unit(1206) and linear interpolation.

Abstract: An image signal processor and an image signal processing method thereof are provided to improve image quality without a false contour, a motion blur, and a rounding error by moving each sub field according to a movement vector. A frame delay unit(110) generates a light emitting pattern without non-emission subfield between a first subfield and a second subfield comprising one frame of an input image signal. A motion estimation unit(120) estimates and outputs the motion vector between a prior frame and a current frame by using the pixel value of the prior frame outputted from the frame delay unit and the pixel value of the current frame. An inverse gamma correction unit(130) performs an inverse gamma correction of the inputted RGB image signal and outputs the corrected signal. A pattern generating unit(140) generates the light emitting pattern of each subfield comprising one frame. A pattern moving unit(150) moves the light emitting pattern generated based on the motion vector estimated in the motion estimation unit. A dither coefficient output unit(160) outputs the dither value given according to the frame order of the inputted RGB image signal and a position of the pixel. A pattern selection unit(170) selects and outputs one among the subfield candidate groups for expressing the light emitting pattern according to the dither value outputted in the dither coefficient output unit.
