20130120529 | VIDEO SIGNAL PROCESSING DEVICE AND VIDEO SIGNAL PROCESSING METHOD - A video signal processing device includes: a stereo conversion unit which generates a stereo superimposed signal by performing stereo conversion processing on a superimposed signal obtained by superimposing, on a two-dimensional video signal, an additional information signal indicating additional information to be combined with a two-dimensional video and displayed, and shifts a first locating signal indicating a position of the additional information in the two-dimensional video, according to an amount of shift caused by the stereo conversion processing on the additional information signal, to generate a second locating signal indicating a position of the additional information in a video indicated by the stereo superimposed signal; and a correction unit performs, on the stereo superimposed signal, quality correction for an area other than an area located by the second locating signal. | 05-16-2013 |
20140112646 | IMAGE DISPLAY DEVICE AND IMAGE PROCESSING DEVICE - An image display device includes: an interpolation phase generator that generates an interpolation phase on the basis of downsampling frame information representing a downsampling timing at which at least one frame image of the image signal is thinned, and an interpolation frame generator that generates an interpolation frame image corresponding to the interpolation phase. The interpolation phase generator generates the interpolation phase such that a phase distance between a first interpolation frame image from among a plurality of interpolation frame images within one period of downsampling periods, and a second interpolation frame image that follows the first interpolation frame image becomes equal to a phase distance between mutually adjacent interpolation frame images obtained when phase distances between a plurality of interpolation frame images are equalized within one period of the downsampling periods. | 04-24-2014 |
