摘要： PROBLEM TO BE SOLVED: To provide an image display device, having excellent video characteristics, contrast and power consumption, and preventing unintended pseudo contour and image blur by disposing an overdrive part in a stage subsequent to an area control processing part.
SOLUTION: A gain calculator part 151 calculates a ratio Gmax0/Gmax1 as gain for each image signal supplied to each segmented region of a liquid crystal panel. The Gmax1 represents a maximum gradation in one frame period of an image signal to be supplied to each region. The Gmax0 represents a maximum gradation to be determined depending on the number of bits in the image signal. A multiplier 152 multiplies an image signal subjected to frame frequency conversion in a frame frequency conversion unit 14 by the gain to generate an image signal fa subjected to the area control processing, with respect to each segmented region. The overdrive unit 17 emphasizes the image signal fa subjected to the area control processing, using an image signal fb generated by delaying the image signal fa subjected to the area control processing for one frame period.

摘要： PROBLEM TO BE SOLVED: To provide a moving vector detection apparatus for generating an interpolated image, with less unnaturalness caused by the misdetection of a moving vector, by using a single moving vector detection circuit.
SOLUTION: The single moving vector detection circuit 21 detects a plurality of moving vector candidates from a correlation detection signal PV11 output from a correlation detection circuit 3, uses a moving vector MV12 one frame before, which is input from a moving vector memory 22, as a reference moving vector and detects the moving vector candidate having a vector direction most close to a vector direction indicated by the reference moving vector as a moving vector. Since the moving vector detection circuit 21 can detect a moving vector having closer correlation in a continuous frame flow, errors in the detection of moving vectors can be reduced.
