Abstract:
1. A three-dimensional display apparatus for displaying a three-dimensional image comprising: a display unit formed by arranging a plurality of pixels, each pixel having a plurality of light emitting points; a variable focal length lens panel including a plurality of variable focal length lenses arranged to correspond to each of said pixels forming said display unit; a display data generation unit for generating a plurality of display data arranged according to a plurality of depths in a three-dimensional space viewed by a viewer, said display data being based on data of a three-dimensional image to be displayed on said display unit; a lens driving unit for varying the focal length of each of said variable focal length lenses according to each depth of said display data; and a display driving unit for driving said light emitting points according to each depth of said display data, wherein at each depth of said generated display data, virtual images of plural ones of said light emitting points at plural ones of said pixels are formed by said plurality of variable focal length lenses such that the virtual images are perceived by the viewer as being overlapped, wherein said lens driving unit controls the focal length of said variable focal length lenses according to each depth of said display data in synchronization with displaying said display data on said display unit by display driving unit, and wherein said display data generation unit generates said display data to cause one of said light emitting points at a prescribed position to be driven in selected ones of the plural pixels in a surrounding area of any one of said plural pixels serving as a center so that the virtual images of said driven light emitting points are perceived as being overlapped.
