VIDEO SIGNAL PROCESSING APPARATUS AND VIDEO SIGNAL PROCESSING METHOD
First Claim
1. A video signal processing apparatus for processing a video signal for displaying an image in which right-eye and left-eye images having a parallax alternate every frame, the video signal processing apparatus comprising:
- a first transformation section configured to transform the video signal into a luminance signal;
a setting section configured to set a crosstalk ratio based on amounts of crosstalk occurring in two successive frames;
a calculation section configured to, on the basis of the luminance signal of a current frame output from the first transformation section and the crosstalk ratio, calculate a correction luminance signal for correcting an amount of crosstalk occurring in a next frame following the current frame;
a second transformation section configured to transform the correction luminance signal to generate a correction video signal; and
a correction section configured to add the correction video signal to a video signal of the next frame.

Abstract
An image-luminance transformation section receives a video signal on a frame basis, and transforms the video signal into a luminance signal in each frame. A crosstalk ratio setting section sets a crosstalk ratio. An amount-of-correction calculation section calculates a correction luminance signal, for correcting a video signal of a frame n, using a luminance signal of a frame n−1, a luminance signal of the frame n, and the crosstalk ratio. A luminance-image transformation section transforms the correction luminance signal into a correction video signal. A correction section adds the correction video signal to the video signal of the frame n to generate a video signal of the frame n in which the amounts of crosstalk have been corrected.

11. A video signal processing method performed by an apparatus for processing a video signal in which right-eye and left-eye images having a parallax alternate every frame, the video signal processing method comprising:
-
a first transformation step of transforming the video signal into a luminance signal equivalent to a luminance corresponding to characteristics of a display for displaying a stereoscopic image; a step of, on the basis of the luminance signal of a current frame output in the first transformation step and a crosstalk ratio based on amounts of crosstalk occurring in two successive frames, calculating a correction luminance signal for correcting an amount of crosstalk occurring in a next frame following the current frame; a second transformation step of performing on the correction luminance signal a transformation inverse to the transformation performed in the first transformation step, to generate a correction video signal; and a step of adding the correction video signal to a video signal of the next frame.
