Abstract
A method and combined video display and camera system are disclosed. In one embodiment, the system comprises a first sheet and a second sheet oriented parallel to the first sheet, the second sheet including a light diffuser. A light source is placed along an edge of the second sheet, wherein the second sheet diffuses light generated by the light source. One or more cameras are placed behind the second sheet to capture an image through the second sheet and the first sheet.
Claims12
A method for reducing defects in an image captured by a camera, the defects caused by a flat panel screen of a display, comprising:
- providing a partially transparent display pixel during a time period when the camera is exposed;
- estimating an average transparency of the partially transparent display pixel;
- calculating values, as a function of the average transparency, for insertion in an occlusion map;
- inserting the values in the occlusion map;
- and
- estimating a corrected image using the occlusion map and the image captured by the camera,
- wherein estimating the corrected image comprises numerically dividing one or more pixel values of the image captured by the camera by the values inserted in the occlusion map.
