Claim:
1. A video output device, comprising: a drawing portion drawing successively images corresponding to image information at a first frequency; and an output portion outputting to a three-dimensional television receiver two pieces of image information based on the images corresponding to the image information successively drawn by said drawing portion with the two pieces of image information being packed as first image information and second image information in a form of three-dimensional image information containing therein the first image information and the second image information which are to be transmitted to the three-dimensional television receiver adapted to perform three-dimensional display at a second frequency approximately half of the first frequency; a drawing buffer successively storing therein image information on the images which are drawn by said drawing portion, wherein said output portion includes: a frame storage determination unit determining whether or not the image information is stored in said drawing buffer for a first time period corresponding to a first half time period corresponding to the second frequency, and for a second time period corresponding to a second half time period corresponding to the second frequency, wherein said outputting buffer stores therein the image information on the images which are successively drawn in accordance with a determination result made by said frame storage determination unit, wherein said output portion further includes: and, when the image information is not stored in said drawing buffer either for the first time period or for the second time period, said outputting buffer stores the complementary frame in said first area.
