Abstract
A display unit displays independent pictures for a plurality of viewing directions on a single screen based on a video signal. A conversion processing unit generates new pixel data based on original pixel data constituting a picture source signal. An extraction processing unit extracts a predetermined number of pixel data for generating the video signal from the new pixel data. The conversion processing unit generates the new pixel data based on arbitrary original pixel data and at least adjacent original pixel data that is adjacent to the arbitrary original pixel data, considering an extraction of the pixel data by the extraction processing unit.
