20080211973 | Spectrum Sequential Display Having Reduced Cross Talk - A color display device, a drive circuit for a color display device, a method, a signal and a computer-readable medium for reducing electro-optical cross talk that occurs in a display that is operated in Spectrum Sequential mode is disclosed. The invention eliminates annoying visible artefacts, such as contouring, noise, or color deviation, which normally are introduced by this cross talk by compensating for the cross talk. According to embodiments of the invention, a drive signal (R′,G′,B′) to drive picture elements of the display is altered in video processing circuitry (MPC, XTC, SC) and/or software, in dependence on one or more properties of different spectra from a light source ( | 09-04-2008 |

20100039517 | FILM CADENCE DETECTION - A film cadence in a video signal (VA) is detected in the following manner Successive classification indications (BC | 02-18-2010 |
20100149415 | SYSTEM AND METHOD FOR THE DETECTION OF DE-INTERLACING OF SCALED VIDEO - A system, apparatus, and method are provided for a video detector that computes a measure of how much a given video content resembles one of a de-interlaced video content or a progressive video content. More particularly, the present invention determines the position of original and interpolated lines and the scaling factor of an input content whenever that content was scaled after de-interlacing. | 06-17-2010 |
20100188531 | IMAGE DETAIL ENHANCEMENT - A method of enhancing details in an input image. The input image comprises input pixels, which have input pixel values (IPV) limited to a range (RA). The method comprises average filtering ( | 07-29-2010 |
20110019083 | Frame-Rate Conversion - A method of generating presentation time stamps, PTSs, for motion-compensated frame-rate conversion of a sequence of frames. In one aspect, the method comprises for each new frame: determining an average difference between the capture time-stamps of recent consecutive new frames; and generating the PTS based on the capture time-stamp of a previous new frame and the average difference. In another aspect, the method comprises detecting a first cadence and a second different cadence in the sequence of frames; and generating a PTS for each new frame defined by the first cadence, such that in each case the difference between the PTSs of consecutive new frames is intermediate between the true interval between those frames according to the first cadence and the true interval between them according to the second cadence. | 01-27-2011 |
20110142289 | SYSTEM AND METHOD FOR MOTION ESTIMATION USING IMAGE DEPTH INFORMATION - A system and method for motion estimation involves obtaining input image frames, where the input image frames correspond to different instances in time, and performing motion estimation on the input image frames using depth information from the input image frames, where the depth information from an input image frame indicates how far a pixel in the input image frame is located from a surface of a three dimensional space. | 06-16-2011 |
20120120252 | SYSTEM AND METHOD FOR THE DETECTION OF DE-INTERLACING OF SCALED VIDEO - A system, apparatus, and method are provided for a video detector that computes a measure of how much a given video content resembles one of a de-interlaced video content or a progressive video content. More particularly, the present invention determines the position of original and interpolated lines and the scaling factor of an input content whenever that content was scaled after de-interlacing. | 05-17-2012 |
