A timing solution for projector camera devices and systems

摘要

An imaging system includes an integrated projector (50) that projects images on to an external display (20) surface and a digital camera (30) that records gestures and/or other objects that are in or illuminated by the projected images. The camera (30) and/or the projector (50) generate a timing signal to synchronize a refresh rate of the projector (50) with an exposure time of the digital camera (30). The synchronization reduces or eliminates interference patterns that may be caused by gestures in or illuminated by the projected image, and allows the digital camera (30) to more accurately detect the gestures.
