Patent number: 9204086Abstract: A method and apparatus of frame rate conversion where descriptive information relating to an input video signal is transmitted to the frame rate converter along with the input signal. The descriptive information is used to interpolate frames, allowing the interpolator to make pixel analysis using the descriptive information relating to the original signal. The descriptive information is derived by a compositor/scaler and is transmitted to the frame rate converter with the composited/scaled signal. There may be multiple input signals that are composited to make a final composited video output such as a picture-in-picture display. The information may be transmitted in-band with the video signal received by the frame rate converter. Alternatively, the descriptive information may be transmitted in a separate stream in a side-band manner. In another embodiment, the descriptive information may be transmitted to the frame rate converter separate from the video input source as commands or packets.Type: GrantFiled: July 17, 2008Date of Patent: December 1, 2015Assignee: BROADCOM CORPORATIONInventors: Samir N.

Patent number: 8879834Abstract: A method and apparatus for reduced complexity video and image processing with special chroma handling are disclosed. Frame-type decisions are made on a video stream made up of a sequence of frames. A first subset of the frames are selected to be monochrome and generated without chroma data. A second subset of the frames are selected to be in color and generated with chroma components. In one embodiment, the first subset of frames includes odd frames and the second subset of frames includes even frames in the video stream. Under higher video frame rates, the lack of color in every other frame is not visible to the end viewer. Accordingly, subsequent processing of the output video stream permits luma-only processing of many frames in the video stream, extensively reducing the amount of computation.Type: GrantFiled: December 10, 2012Date of Patent: November 4, 2014Assignee: Broadcom CorporationInventors: Kathleen Burns, Larry Pearlstein

Publication number: 20140125642Abstract: A device includes ocular image processing features. The device obtains ocular image data without requiring artificial lenses to capture the ocular image data. The device may, for example, obtain sensor data from a touch sensor associated with a display, recognize ocular image data within the sensor data, and process the ocular image data for any reason. This processing may occur regardless of the fact that the intended purpose of the sensor data was not for ocular imaging, but was intended for another purpose, such as detecting touch interactions with the display.Type: ApplicationFiled: November 5, 2012Publication date: May 8, 2014Applicant: Broadcom CorporationInventors: Larry Pearlstein, Michael Erwin

Patent number: 8610826Abstract: A video processing system may receive a current raw video frame and may estimate motion between the current frame and a previous frame to determine motion vectors (mv). Based on the same mvs, motion compensated (MC) noise reduction may be performed and MC frame rate conversion (FRC) may generate a new frame. The previous frame may be noise reduced and/or a raw video frame. A MC frame may be generated based on the previous video frame and the mvs. Noise reduction may comprise blending the current raw frame with the MC frame. A blending factor may be determined based on similarity between pixels of the current video frame and MC pixels of the previous frame. The mvs may be scaled for FRC. Noise reduction may be performed in parallel and/or prior to the FRC depending on whether raw or noise reduced frames are utilized.Type: GrantFiled: August 27, 2009Date of Patent: December 17, 2013Assignee: Broadcom CorporationInventors: Dongsheng Wu, Larry Pearlstein
