Patent ID: 7967444

Claim:
A multi-resolution digital table display system, adapted for integrally displaying an image picture with multiple resolutions, comprising: a table, comprising: a plurality of legs; and a projection screen supported by the legs, wherein the legs and the projection screen together define an accommodation space under the table; a peripheral projection device, accommodated in the accommodation space, and being adapted for projecting a pre-processed peripheral image with a first resolution at a projection screen, wherein the pre-processed peripheral image comprises at least a reserved area having no pixel data displayed thereby; a foveal projection device, accommodated in the accommodation space, and being adapted for projecting a pre-processed foveal image with a second resolution at the projection screen, wherein the foveal image is displayed in the reserved area of the peripheral image at the projection screen only, and the first resolution is lower than the second resolution; and an image module, adapted for providing the pre-processed peripheral image to the peripheral projection device for displaying the same with the first resolution at the projection screen, and providing the pre-processed foveal image to the foveal projection device for displaying the same with the second resolution at the projection screen; wherein the image picture comprises a plurality of objects defined therein, and each of the objects is defined with coordinates included in a coordinate system of the image picture, the multi-resolution digital table display system further comprising: an infrared ray (IR) source, projecting an IR beam to the projection screen; an IR camera, shooting towards the projection screen for capturing a reflecting IR image picture; an analysis module, analyzing the captured reflecting IR image picture and finding out a concentration area of the reflecting IR image picture; a selection module, for defining the object as selected when the concentration area to some degree overlaps the coordinates of the object to some degree; and a displacement module, for redisplaying the image picture corresponding to the selected object according to displacement data about a detected motion of the concentration area.
