    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: 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.

    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.
