Patent number: 7881547Abstract: The invention provides for automatically identifying the location of a displayed video window based upon a characterization of selected portions of the image for realness based upon a distribution of luminance values for the selected portions. The image is then searched mathematically for a large rectangle of realness, and if found, a similar operation is performed in a smaller rectangle around each of the edges of the large rectangle, in turn, zooming in to a resolution of one pixel, thus identifying the position of the edge. This process can be repeated as often as necessary in order to maintain a fix on the edges of the video window.Type: GrantFiled: November 30, 2006Date of Patent: February 1, 2011Assignee: Genesis Microchip Inc.Inventor: Greg Neal

Patent number: 7826680Abstract: The invention provides for calculating the sum of the luminance values of all pixels in each of a number of regions making up the whole image. A histogram is then created of all the sums of luminance at the end of each frame. The histogram is then rescaled such that the luminance range is normalized. Once the histogram has been created, an appropriate transfer function is created using the integrated luminance histogram for the frame. In this way detail within significant objects in the image are enhanced since the average luminance of objects in an image are weighted more than then the luminance of individual pixels providing a more realistic transfer function.Type: GrantFiled: September 21, 2006Date of Patent: November 2, 2010Assignee: Genesis Microchip Inc.Inventor: Greg Neal

Patent number: 7801257Abstract: An over-sampled sequence detector operates on sampled data and tracks the detection reliability of the sampled data. The detector separately analyzes sample sequences for different sampling phases and then picks a sample sequence that allows for the most reliable detection. For the different sampling phases, the detector inspects some amount of look-behind and look-ahead information in order to improve upon simple symbol-by-symbol detection. The over-sampled information is used to further improve detection performance.Type: GrantFiled: September 28, 2005Date of Patent: September 21, 2010Assignee: Genesis Microchip IncInventor: Alexander Julian Eglit

Patent number: 7683868Abstract: An extended overdrive table uses the saturation regions to store useful data that conformably extends the unsaturated region in a natural way. This extended overdrive table reduces the size of any interpolation errors when straddling crossover points to acceptable levels without requiring storing or using any crossover data. In addition, since the saturation regions are used to hold the new data, no additional storage requirements are introduced. The numeric range of the extended table is increased and it is therefore supposed that the bit depth of the table entries is increased, but the table can be resealed to retain the original bit depth with insignificant loss of accuracy. Also, the new data incorporated into the saturation regions allows run time calculation of the pixel attained at the end of the frame time that is needed as the start of the pixel for the next cycle.Type: GrantFiled: February 18, 2005Date of Patent: March 23, 2010Assignee: Genesis Microchip Inc.Inventor: Matthew Halfant
