Abstract: A trackable camera beacon is provided that is mountable onto a camera, so that the camera can be more easily tracked and automatically controlled. The camera beacon obtains lens data from the lens of a camera, position data corresponding to the camera beacon, and outputs a unified and synchronized data packet.

Abstract: A trace subsystem of an emulation system may generate differential frame data based upon successive frames. If one compression mode, the trace subsystem may set a flag bit and store differential frame data if there is at least one non-zero bit in the differential frame data. If the differential frame data includes only zero bits, the trace subsystem may set the flag bit without storing the frame data. In another compression mode, the computer may further compress the differential data if the frame data includes one (one-hot) or two (two-hot) non-zero bits. The controller may set flag bits to indicate one of all-zeroes, one-hot, two-hot, and random data conditions (more than two non-zero bits). For one-hot or two-hot conditions, the controller may store bits indicating the positions of the non-zero bits. For random data conditions, the controller may store the entire differential frame.

Abstract: The apparatus generates simulated strobe effects in the form of video or still image output in response to receipt of a video stream, and without the need of additional strobe hardware. Videos of a moving target object are categorized into one of multiple categories, from which a strobe generation process is selected.

Motion segmentation is applied to the foreground object in each image frame, and a foreground mask is updated as each checkpoint is reached along the object trajectory, such as in response to time differences between checkpoints. Potential applications include special features for camcorders, digital cameras, or computer software.
