EMBEDDED CMOS CAMERA IN A LAPTOP COMPUTER

摘要

A laptop computer includes a video camera mounted to the lid, preferably embedded into the bezel above the display. The camera includes a CMOS imaging array, video data from which is communicated along a dedicated path from the camera to a graphics controller for output to the display, thereby bypassing the system bus. This makes it possible to display full frame, full data rate video with minimum impact on the overall system performance. Panning and zooming are implemented by software that controls the addresses in the pixel array from which data are transferred to the graphics controller's associated display memory.
