Latest Patents

“Close Focus with GPU” describes systems and methods that automatically focus or refocus a digital camera when a scene changes. The camera scans from its closest settable distance toward farther distances until it detects the nearest object, then focuses at that distance and performs a finer scan. One embodiment uses a calculated dynamic movement threshold to determine when refocusing is needed.

“Transform Space Difference Compression” presents a method for reducing the data transmitted during remote presentation sessions. Graphical data is transformed before differences between successive frames are calculated. The resulting delta is encoded and sent to a client, which uses it with the previous frame to reconstruct the current image. The approach aims to reduce bandwidth while preserving the decoded image’s fidelity.
