Systems for capturing images through a display
First Claim
1. A visual-collaborative system comprising:
- a display screen having a first surface and a second surface;
a first projector positioned to project images onto a projection surface of the display screen, wherein the projected images are observable by viewing the second surface, and wherein the projected images are transmitted onto the projection surface at a first set of wavelengths of a first color and a first set of wavelengths of a second color; and
a first camera system positioned to capture images of objects through the display screen, the first camera system including a first filter disposed between a first camera and the first surface, wherein the first filter passes light at a second set of wavelengths of the first color and a second set of wavelengths of the second color received by the camera but substantially blocks the projected images transmitted onto the projection surface at the first set of wavelengths of the first color and the first set of wavelengths of the second color by the first projector, wherein the first and the second sets of wavelengths of the first color are substantially non-overlapping, and wherein the first and the second sets of wavelengths of the second color are substantially non-overlapping.

Abstract
Embodiments of the present invention are directed to a visual-collaborative system enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system comprises a display screen, a camera system, and a projector. The display screen has a first surface and a second surface, and the camera system is positioned to capture images of objects through the display screen. The projector is positioned to project images onto a projection surface of the display screen, wherein the projected images can be observed by viewing the second surface. The system includes a first filter disposed between the camera and the first surface, where the first filter passes light receives by the camera but substantially blocks the light that is produced by the projector.

17. A method comprising:
-
projecting images by a projector onto a projection surface of the display screen, wherein the projected images are transmitted onto the projection surface at a first set of wavelengths of a first color and a first set of wavelengths of a second color; and simultaneously capturing images of objects through the display screen with a camera system, the camera system including a first filter disposed between a camera and the first surface of the display screen, wherein the first filter passes light at a second set of wavelengths of the first color and a second set of wavelengths of the second color received by the camera but substantially blocks the projected images transmitted onto the projection surface at the first set of wavelengths of the first color and the first set of wavelengths of the second color by the projector, wherein the first and the second sets of wavelengths of the first color are substantially non-overlapping, and wherein the first and the second sets of wavelengths of the second color are substantially non-overlapping. - View Dependent Claims (18, 19)
