20110298965 | SCENE-AWARE AUTOMATIC-EXPOSURE CONTROL - A scene-aware auto-exposure control process stabilizes changes in a camera's auto-exposure settings so as to reduce lighting and color flicker during image capture operations. A metric, referred to as the Modified Adjusted Luminance (MAL) metric, is defined to remain relatively constant as long as the lighting of the scene being captured remains relatively constant. Thus, scene changes such as an object moving into, out of, or around in a scene do not significantly affect the MAL metric's value and do not, therefore, trigger an exposure adjustment. Once the MAL metric indicates a scene's lighting is stable, the camera's auto-exposure operation may be suppressed. As long as incoming frames indicate a stable lighting condition (based on the MAL metric), auto-exposure operation may remain suppressed. When incoming frames result in a substantially different MAL over a specified number of frames, auto-exposure operation may be restored. | 12-08-2011 |

W represents a scaling factor and O represents an offset value. Given a frame of input video to be coded, a prediction match may be established one or more reference frames. The input frame may be parsed into a plurality of regions. Thereafter the scaling factor W and/or offset value O may be derived by developing a system of equations relating a predicted pixel to the pixel in the frame by the scaling factor W and/or offset value O. Equations within the system may be prioritized according to priority among regions, and scaling factor W and/or offset value O may be solved for. The scaling factor W and/or offset value O may be used during weighted prediction of the input frame. | 08-16-2012 |
20130003846 | FRAME ENCODING SELECTION BASED ON FRAME SIMILARITIES AND VISUAL QUALITY AND INTERESTS - A system an method for determining to select frames from a video sequence that have high visual appeal and can be coded at high quality when frame rates of coded video drop to such low levels that perceptual sensations of moving video are lost.

20130195178 | OBJECT DETECTION INFORMED ENCODING - Embodiments of the present invention provide techniques for coding video data efficiently based on detection of objects within video sequences. A video coder may perform object detection on the frame and when an object is detected, develop statistics of an area of the frame in which the object is located. The video coder may compare pixels adjacent to the object location to the object's statistics and may define an object region to include pixel blocks corresponding to the object's location and pixel blocks corresponding to adjacent pixels having similar statistics as the detected object. The coder may code the video frame according to a block-based compression algorithm wherein pixel blocks of the object region are coded according to coding parameters generating relatively high quality coding and pixel blocks outside the object region are coded according to coding parameters generating relatively lower quality coding. | 08-01-2013 |
20130235942 | SIGNAL SHAPING TECHNIQUES FOR VIDEO DATA THAT IS SUSCEPTIBLE TO BANDING ARTIFACTS - Video coding systems and methods protect against banding artifacts in decoded image content. According to the method, a video coder may identify, from content of pixel blocks of a frame of video data, which pixel blocks are likely to exhibit banding artifacts from the video coding/decoding processes. The video coder may assemble regions of the frame that are likely to exhibit banding artifacts based on the identified pixel blocks' locations with respect to each other. The video coder may apply anti-banding processing to pixel blocks within one or more of the identified regions and, thereafter, may code the processed frame by a compression operation. | 09-12-2013 |
20130329064 | TEMPORAL ALIASING REDUCTION AND CODING OF UPSAMPLED VIDEO - Embodiments of the invention provide techniques for upsampling a video sequence for coding. According to the method, an estimate of camera motion may be obtained from motion sensor data. Video data may be analyzed to detect motion within frames output from a camera that is not induced by the camera motion. When non-camera motion falls within a predetermined operational limit, video upsampling processes may be engaged. In another embodiment, video upsampling may be performed by twice estimating image content for a hypothetical new a frame using two different sources as inputs. A determination may be made whether the two estimates of the frame match each other sufficiently well. If so, the two estimates may be merged to yield a final estimated frame and the new frame may be integrated into a stream of video data. | 12-12-2013 |
20130329799 | PREDICTIVE VIDEO CODER WITH LOW POWER REFERENCE PICTURE TRANSFORMATION - Video coders may perform perspective transformation of reference frames during coding in a manner that conserves processing resources. When a new input frame is available for coding, a camera position for the input frame may be estimated. A video coder may search for reference pictures having similar camera positions as the position of the input frame and, for each reference picture identified, the video coder may perform a prediction search to identify a reference picture that is the best prediction match for the input frame. Once the video coder identifies a reference picture to serve as a prediction source for the input frame, the video coder may derive a transform to match the reference frame data to the input frame data and may transform the reference picture accordingly. The video coder may code the input frame using the transformed reference picture as a prediction reference and may transmit coded frame data and the camera position of the input frame to a decoder. Thus, the video coder may perform derivation and execution of transforms on a limited basis which conserves system resources. | 12-12-2013 |

20090279652 | Synchronizing Clocks Across a Communication Link - Apparatus, system and method for synchronizing one or more clocks across a communication link. A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. The synchronization signal receipt time indicated by the correlation sample sequence may be refined by interpolating the correlation sample sequence around a best correlation sample to locate a best interpolation at an interpolation resolution smaller than the sample resolution. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. After initialization, all slave clock errors are preferably accumulated to prevent long-term slip between the slave and master clocks. Formerly independent master and slave clocks synchronized across the communication link constitute a noncommon clock which may be compared on each side of the link to secondary independent clocks, and the secondary independent clocks may then be separately synchronized by adjusting one to have the same difference from its local noncommon clock as the secondary clock on the other side of the link has from its local noncommon clock. | 11-12-2009 |
