| 20080198264 | METHODS AND SYSTEMS FOR IMPROVING LOW RESOLUTION AND LOW FRAME RATE VIDEO - Systems and methods are provided for improving the visual quality of low resolution and/or low frame rate video content displayed on large-screen displays. A video format converter may be used to process a low resolution and/or low frame rate video signal from a media providing device before the video is displayed. The video format converter may detect the true resolution of the video and deinterlace the video signal accordingly. The video format converter may also determine the frame rate of a video and may increase the frame rate if the received frame rate is below a certain threshold. For videos that are also low in quality, the video format converter may reduce compression artifacts and apply techniques to enhance the appearance of the video. | 08-21-2008 |
| 20080211959 | METHODS AND SYSTEMS FOR IMPROVING LOW-RESOLUTION VIDEO - Systems and methods are provided for improving the visual quality of low-resolution video displayed on large-screen displays. A video format converter may be used to process a low-resolution video signal from a media providing device before the video is displayed. The video format converter may detect the true resolution of the video and deinterlace the video signal accordingly. For low-resolution videos that are also low in quality, the video format converter may reduce compression artifacts and apply techniques to enhance the appearance of the video. | 09-04-2008 |
| 20090316050 | SPLIT EDGE ENHANCEMENT ARCHITECTURE - A system and method for enhancing the detail edges and transitions in an input video signal. This enhancement may be accomplished by enhancing small detail edges before up-scaling and enhancing large amplitude transitions after up-scaling. For example, detail edge enhancement (detail EE) may be used to enhance the fine details of an input video signal. An edge map may be used to prevent enhancing the large edges and accompanying mosquito noise with the detail enhancement. Noise may additionally be removed from the signal. After the fine details are enhanced, the signal may be up-scaled. Luminance transition improvement (LTI) or chrominance transition improvement (CTI) may be used to enhance the large transitions of the input video signal post scaler. | 12-24-2009 |
| 20100046628 | Systems and Methods for Perceptually Lossless Video Compression - In one embodiment, the present invention includes a method for compressing video data. The method comprises segmenting a video frame, selecting a coding mode, and encoding. The segmenting includes segmenting the video frame of the video data into a sequence of coding blocks. The selecting includes selecting the coding mode from a plurality of coding modes. The selecting of the coding mode is based on an allowable bit budget and occurs for each coding block. The encoding includes encoding each coding block based on the coding mode. The allowable bit budget varies according to a bit utilization of prior encoded coding blocks and varies such that the video frame is does not exceed a specified compression ratio. | 02-25-2010 |
| 20100134496 | BIT RESOLUTION ENHANCEMENT - Devices, systems, apparatuses, methods, and other embodiments associated with bit resolution enhancement are described. In one embodiment, an apparatus includes logic configured to produce a high-resolution pixel from a low-resolution pixel. The apparatus includes logic configured to classify the high-resolution pixel as being in a smooth region of an image based on at least one of a gradient value and a variance value associated with the low-resolution pixel. The apparatus includes logic configured to selectively re-classify the high-resolution pixel as not being in the smooth region of the image based on a set of neighboring high-resolution pixels associated with high-resolution pixel. The apparatus includes logic configured to selectively filter the high-resolution pixel based on whether the high-resolution pixel remains classified as being in the smooth region of the image. | 06-03-2010 |
| 20100166335 | FILM GRAIN GENERATION AND ADDITION - High-frequency noise is generated that approximates the appearance of traditional “film grain” for a digital video signal. By adding a relatively small amount of film grain noise, the video can be made to look more natural and more pleasing to the human viewer. The digital film grain generation can be used to mask unnatural smooth artifacts in digital video such as “blockiness” and “contouring” in the case of compressed video and/or used to provide visual enhancements or special effects to any digital video stream. The digital film grain generator can control grain size and the amount of film grain to be added. | 07-01-2010 |
| 20100253838 | CADENCE DETECTION IN PROGRESSIVE VIDEO - Devices, methods, and other embodiments associated with cadence detection are discussed. In one embodiment, an apparatus analyzes a progressive video stream and determines a cadence pattern from the progressive video stream. | 10-07-2010 |
| 20100265334 | AUTOMATIC ADJUSTMENTS FOR VIDEO POST-PROCESSOR BASED ON ESTIMATED QUALITY OF INTERNET VIDEO CONTENT - A system including a quality estimation module configured to estimate a visual quality of video content based on data from a decoder module. The system further including a settings database configured to store a plurality of predetermined settings. The settings database outputs at least one of the predetermined settings in response to the visual quality. The system further including a video post-processor module configured to automatically adjust settings of the video post-processor module based on the at least one of the predetermined settings. The video content is processed based on the settings of the video post-processor module that were automatically adjusted. | 10-21-2010 |
| 20100295767 | LIQUID CRYSTAL DISPLAY BACKLIGHT CONTROL - To improve contrast ratio of the image on a backlit display plane such as a liquid crystal display (“LCD”), each area of the image that has separately controllable backlight may be given full backlight until an average or composite brightness of the image in that area is less than a threshold value at which light leakage through the image from full-strength backlight begins to be noticable by a viewer. For image areas with composite brightness less than that threshold, backlight brightness may be reduced in proportion to how much below the threshold the area's composite image brightness is. Backlight brightness may also be adjusted for other image aspects such as (1) the presence of bright pixels in an otherwise relatively dark area, (2) whether the area is adjacent to one or more other areas in which the image information is in motion, and/or (3) time-averaging of image information over several successive frames of such information. | 11-25-2010 |
| 20110013208 | SYSTEM AND METHODS FOR GAMUT BOUNDED SATURATION ADAPTIVE COLOR ENHANCEMENT - System and methods for gamut bounded saturation adaptive color enhancement are provided. Color enhancement incorporating gamut bounded saturation enhances colors of an pixel from a source color gamut such that the resulting color is within a target color gamut. This resulting color may, for example, take advantage of an expanded target color gamut of a display. Gamut bounded saturation may be implemented independently or in combination with RGB bounded saturation. | 01-20-2011 |
