A motion vector detector detects, using pixel data in at least two real frames in an input video signal, a motion vector MVnecessary 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 MVto decrease the magnitude of motion vector MVwhen the magnitude of motion vector MVexceeds a predetermined threshold, and outputs it as a motion vector MV

Motion vector correction device and method and video signal processing apparatus and method

A 3D parallax value detection unit detects a parallax value between a left-eye image signal and a right-eye image signal in a stereoscopic video signal. A stereoscopic degree determination unit determines a stereoscopic degree of the stereoscopic video signal based on the parallax value. In response to the stereoscopic degree, an image signal conversion unit obtains an amount of pixel shift, by which a pixel of the left-eye image signal or the right-eye image signal is to be shifted, and shifts the pixel by the amount of pixel shift. In such a way, a parallax of the left-eye image signal or the right-eye image signal is adjusted.

A depth signal generation apparatus includes a depth signal estimation unit, a depth signal histogram generator, and a depth signal level converter. The depth signal estimation unit estimates a depth signal for each pixel of a predetermined unit in a video image signal. The depth signal histogram generator divides a range of a depth signal level which the depth signal can have, into depth signal level regions each having a predetermined range size, determines which depth signal level region includes the depth signal for each pixel, counts the number of pixels included in each depth signal level region to generate depth signal histogram data according to the count value. The depth signal level converter generates a depth signal level conversion curve according to the depth signal histogram data and generates a depth signal after level conversion by executing depth signal level conversion according to the depth signal level conversion curve.

Correlation detectorsandemploy two different correlation detecting methods to determine correlations. Correlation comparatorsandoutput correlation values DFand DF, and motion vectors MVand MVin directions representing largest correlation values. A correlation comparatorselects one of the motion vectors larger in correlation, as a motion vector MV, to output an interpolation control signal FSto determine an interpolation method at an interpolator. The interpolatoris operative in accordance with the interpolation control signal FS, to select any one out of two different one-side interpolations and a both-side interpolation, to generate interpolation pixel data fp
