Abstract:
1. An electronic device comprising: a video generator configured to generate a video signal; a video projector configured to project a video image responsive to the video signal onto a display surface external to the electronic device to cause reflection of the video image; a camera configured to sense the reflected video image from the display surface; and a calibration controller configured to adjust brightness and/or color of a subsequent video image that is projected by the video projector to compensate for differences between the video signal and the reflected video image sensed by the camera; a housing in which the video projector and the camera are fixedly positioned, wherein the camera is pointed in a sufficiently different direction than the video projector so that the camera cannot sense at least a substantial incident portion of the reflected video image from the display surface; and a mirror surface that is movably connected to the housing and is movable between a stored position, where the mirror surface is at least partially recessed within the housing, and an open position where the mirror surface is exposed to an incident portion of the reflected video image from the display surface and reflects the incident portion of the reflected video image to the camera.
