Abstract:
Embodiments provide techniques for providing copy protection from capturing a displayed image using one or more camera devices. Embodiments generate a plurality of frames, based on the received image, such that when the plurality of frames are displayed using at least a threshold refresh rate, the displayed plurality of frames appears as the received image when viewed by a user, and the displayed plurality of frames appears as one of a plurality of other images when captured by an image capture device. The plurality of frames are then output for display on one or more display devices configured to use at least the threshold refresh rate.
