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.

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： 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 repetitive object detecting device includes data-retention and difference-calculation units, an adding unit, a horizontal direction accumulating unit and a small and large comparing unit. Each data-retention and difference-calculation unit carries out, with respect to a plurality of lines, a process for setting as reference pixel data pixel data located at an end of a plurality of pieces of pixel data, and calculating a difference between the reference pixel data and pixel data separated from the reference pixel data by k pixels (2≦k≦maximum number) to obtain difference data by each separated pixel number k. The adding unit adds the difference data in the plurality of lines by each separated pixel number k. The horizontal direction accumulating unit accumulates the added data by each separated pixel number k in a horizontal direction. The small and large comparing unit carries out a small and large comparison with respect to the horizontal accumulated value by each separated pixel number k to decide whether or not the reference pixel data is pixel data which is located in a repetitive object including a certain repetitive pattern.
