International Classification:

G06K 9/40
G06K 9/00

US Classification:

382254, 382162

Abstract:

Methods and systems for restoring image integrity in an image are described. The described methods and systems are particularly applied against an image after determining whether the image has undergone at least one of a color mutation, a non-color mutation, or a combination of a color mutation and a non-color mutation.

Abstract:

Systems and methods for transmitting video frames are described. Specifically, frame rate modification techniques such as blending and/or packing processes are used to translate high frame-rate signals into low-frame rate signals, which are transmitted over limited bandwidth transmission media to a video signal receiver. Information pertaining to the blending and/or packing processes is transferred to the video signal receiver in the form of a map that is used to reconstruct the high frame-rate signals from the low-frame rate signals. The high frame-rate signals may be used by certain types of newer equipment designed to use such signals. However, legacy equipment that cannot use the high frame-rate signals may opt to use certain embodiments described herein that are designed to be backward-compatible. When backward-compatible, the video signal receiver generates suitable low frame-rate signals as well as the high frame-rate signals, thereby accommodating both legacy as well as newer equipment.
