摘要： A vector motion detector is provided which corrects the quantity of a motion vector determined with the block matching technique between a reference block taking a reference pixel extracted from a current frame as its origin and a search block extracted from a reference frame and moving within or along the circumference of a search range and which is outside the search range. The vector motion detector makes the motion vector quantity correction so that the motion vector will fall within the search rang. Thus, it can provide a smooth motion of even an image that moves fast.

摘要： It is determined whether each block (51) including a plurality of pixels extracted from a basic field (30) has an edge or not, and then which state, stationary or non-stationary, each of the pixels forming together the block (51) determined to have an edge is. There is calculated an absolute value of a difference between a pixel determined to be non-stationary and a pixel (91 or 92) in each pixel position in a reference field (40) or pixels (82 to 85) included in the reference field and adjacent to the non-stationary pixel, and a correlation is found between such pixels in consideration according to the calculated difference absolute-value. A motion vector is determined by the block matching method according to results of the determination, and allocated to each of the pixels. Thus, the motion vector of each block is corrected to an accurate one of each of the pixels.

摘要： To realize a motion compensation device capable of more appropriately compensating the movement of a video signal subjected to double-speed conversion. A motion vector between an image of a current field in a double-speed-converted video signal and an image of a reference field that is one frame or two frames later is detected, the pixels of the current field are shifted based on the motion vector and the pixels of the reference field are shifted in an opposite direction based on the motion vector. Then simple averaging or weighted average according to the shift amount is performed on the pixels of the current field and the pixels of the reference field to compensate the current field, thereby being capable of compensating the movement between fields so as to be much smoother than conventional cases.

摘要： An image signal processing unit includes a frame rate conversion circuit performing double frame rate conversion on an input image signal from a first frame frequency to a second frame frequency. When performing frame rate conversion with the motion correction process, a motion vector is determined between a first frame image and a third frame image, and three interpolation frame images are formed through the motion correction process to the first frame image based on the motion vector, and are inserted between the first and third frame images so as to establish the second frame frequency. When performing frame rate conversion without the motion correction process, an interpolation frame image same as the first frame image is inserted between the first and second frame images, and an interpolation frame image same as the second frame image is inserted between the second and third frame images.
