Patent number: 8553113Abstract: A digital image capturing system and method are disclosed. A system incorporating teachings of the present disclosure may include a processing engine that performs digital image processing functions like noise reduction, gain control, white balance and others. In one embodiment, the image capturing system may have a first image sensor operable to capture a first view of a scene and a second image sensor operable to capture a second and different view of the scene. A selector may be employed to selectively route either the first view information or the second view information onto the processing engine. In preferred embodiments, the sensors may be CMOS sensors and, as such, relatively inexpensive. By allowing two inexpensive sensors to share image processing electronics, an image capturing system incorporating teachings of the present disclosure may be able to offer compelling functional characteristics at a reasonable price.Type: GrantFiled: August 20, 2003Date of Patent: October 8, 2013Assignee: AT&T Intellectual Property I, L.P.Inventors: Ahmad C.

Patent number: 8488451Abstract: A system and method of networking with configurable data mapping is disclosed. Data mapping can be utilized to match data transmission types with devices that can efficiently utilize the data transmission type. In one configuration, the data mapping teachings disclosed herein may be utilized to increase the processing efficiency of a home network and insure correct programming is allowed to pass to the correct device by applying a set of data transmission rules to data transmissions between a residential gateway and it's clients. An exemplary method may include receiving a communication at a residential gateway from a client and identifying the client or the source of the transmission. The client may be identified by recognizing one or more of a data transmission type, a client identifier embedded in the transmission, and an identification of a network device hosting the client. The identification may, in some cases, be made automatically upon reception of a data transmission.Type: GrantFiled: March 22, 2005Date of Patent: July 16, 2013Assignee: AT&T Intellectual Property I, LPInventors: Steven M. Wollmershauser, Ahmad C. Ansari
