    摘要: A motion vector detection device includes a motion estimator which detects block motion vectors (MV0) and a motion vector densifier (130). The motion vector densifier (130) further comprises a first motion vector generator (1341), a second motion vector generator (1342-134N), and a motion vector corrector (1371-137N). From each block, the first motion vector generator (1341) generates sub-blocks on a first layer, and generates a motion vector (MV1) for each sub-block on the first layer. In each layer from a second layer through an N-th layer, the second motion vector generator (1342-134N) generates a motion vector (MV7, where k=2 to N) for each sub-block in the layer. The motion vector corrector (1371-137N) corrects the motion vectors of the sub-blocks in layers subject to correction among the first through N-th layers.

    摘要: To interpolate a frame between the current frame and a first delayed frame preceding the current frame, an image processing device generates test interpolation data for the first delayed frame from data in point-symmetric positions in the current frame and in a second delayed frame preceding the first delayed frame. Motion vectors pointing from the first delayed frame to the current frame are found by evaluating different test interpolation data against the actual data of the first delayed frame. These motion vectors are converted to pairs of motion vectors pointing from the first delayed frame and the current frame to the interpolated frame, and these pairs of motion vectors are used to detect occlusion and generate accurate data for the interpolated frame from the data of the first delayed frame and the current frame, excluding occluded data.

    摘要: To interpolate a frame between a first frame and a second frame in a video signal, a motion-compensated interpolated frame is generated and then corrected responsive to detection of a motion vector boundary. Positions at which an absolute value of a first or second derivative of the motion vectors is not less than a predetermined amount are found to be at a motion vector boundary, and the pixel values of the pixels in an area where boundary pixels are concentrated are corrected. Blocks with at least a predetermined proportion of boundary pixels are found to be in an area where boundary pixels are concentrated.

    摘要: To interpolate a frame between two frames of a video signal, sets of reference images are generated, each set having a different resolution level. Motion between the two frames is estimated at each resolution level by using these sets of reference images. For each pixel processed at each resolution level, multiple motion vector candidates are obtained. Information indicating the multiple motion vector candidates is used to select motion search ranges at the next higher resolution level. To determine the motion search range for a pixel, selected motion vector candidates pertaining both to the pixel itself and to its neighboring pixels are used. An interpolated frame of high image quality is thereby obtainable without increased computation and with reduced risk of major image defects due to erroneous motion estimation.

    摘要: An image processing apparatus receives n-bit image data, carries out an α-bit bit extension, and outputs (n+α)-bit image data, where n and α are positive integers. The apparatus also performs an epsilon filtering operation that uses the additional gray levels provided by the bit extension to smooth out false edges caused by the bit extension without smoothing out real edges. The output image preserves both the smoothness of regions of gradual change and the sharpness of abrupt changes in the input image.
