    摘要: Provided is a motion vector detecting apparatus capable of detecting a motion vector based on each of front and rear frames as a starting point while restraining an increase of a circuit scale. A starting pixel generation unit generates starting pixel data based on pixel data in a frame f0 or a frame f1. A search range pixel generation unit generates search range pixel data based on pixel data in the frame f1 or the frame f0. Switches alternately switch the frames f0 and f1 at every line. A motion vector selection unit generates alternately a motion vector based on the frame f0 as a starting point and a motion vector based on the frame f1 as a starting point. A correlation comparing unit selects one motion vector having higher correlation between the motion vectors.

    摘要: A motion vector detector detects, using pixel data in at least two real frames in an input video signal, a motion vector MV1 necessary for generating interpolated pixel data forming an interpolated frame to be inserted between the two real frames. A motion vector corrector corrects the motion vector MV1 to decrease the magnitude of motion vector MV1 when the magnitude of motion vector MV1 exceeds a predetermined threshold, and outputs it as a motion vector MV3.

    摘要: An image display device includes a gain calculator, a multiplier and an overdrive unit. The gain calculator calculates a ratio “Gmax0/Gmax1” as gain, with respect to each segmented region of liquid crystal panel. The symbol “Gmax1” represents a maximum gradation in one frame period of an image signal to be supplied to each segmented region. The symbol “Gmax0” represents a maximum gradation to be determined depending on the number of bits in the image signal. The multiplier multiplies an image signal subjected to frame frequency conversion in a frame frequency conversion unit by the gain to generate an image signal subjected to the area control processing, with respect to each segmented region. The overdrive unit emphasizes the image signal subjected to the area control processing, using an image signal generated by delaying the image signal subjected to the area control processing for one frame period.

    摘要: A motion vector detecting apparatus includes a correlation detecting unit, a repetitive object detecting unit and a motion vector detecting unit. The correlation detecting unit detects correlations among plural pieces of pixel data in plural directions. The repetitive object detecting unit detects whether or not concerned pixel data in which a motion vector is to be detected is located in a repetitive object. The motion vector detecting unit decreases a difference value in a direction coincident with a direction of motion vector having detected at a past time when the concerned pixel data is located in the repetitive object and detects a motion vector.

    摘要: Provided is a motion vector detecting apparatus capable of detecting a motion vector of a pulldown-converted 3D image signal with high precision. A pulldown detecting unit detects whether a 3D image signal is a pulldown-converted image signal. An LR separating unit outputs an LR separation signal separated into left and right image signals in each of frames having the same image content. A frame delay LR separating unit outputs a frame delay LR separation signal separated into left and right image signals in a frame before one repetition period. A motion vector detector detects motion vectors of the left and right image signals, An LR combination unit combines the motion vectors of the left and right image signals to output the combined motion vectors as a motion vector.
