Abstract
Apparatus is disclosed for transmitting video signals which produce images that can be viewed comfortably as two-dimensional images but when viewed through special glasses appear to be three dimensional. An illusion of depth is created for scenes including a moving object by combining one chrominance component of a past field with the luminance component of the current field. By "registering" the moving objects of the past and current fields, the background (stationary) objects of the past and current fields are displaced slightly relative to each other. These displaced images appear in complementary colors and can be viewed normally if the displacement is slight, with an unobjectionable color fringe. When viewed through appropriately filtered glasses, the displaced images create a three dimensional illusion.
