Video processing

<h2 id="video-processor">Video processor</h2> <p>Video processors are often combined with <a href="/facts/Video_scaler/I0StIzsm">video scalers</a> to create a video processor that <a href="/facts/Improved-definition_television/Yv9mLR9e">improves the apparent definition</a> of video signals. They perform the following tasks: </p> <ul><li><a href="/facts/Deinterlacing/zIvhUYdG">deinterlacing</a></li> <li><a href="/facts/Aspect_ratio_(image)/I3vbqVl3">aspect ratio</a> control</li> <li><a href="/facts/Digital_zoom/mfy795NM">digital zoom</a> and <a href="/facts/Panning_(camera)/XcUTDIMN">pan</a></li> <li><a href="/facts/Brightness/e93R5I4b">brightness</a>/<a href="/facts/Contrast_(vision)/zD9F91Je">contrast</a>/<a href="/facts/Hue/9qufc1ap">hue</a>/<a href="/facts/Saturation_(color_theory)/WaePy7Ga">saturation</a>/<a href="/facts/Sharpness_(visual)/xgE5cm2N">sharpness</a>/<a href="/facts/Gamma_correction/cApBLTYj">gamma</a> adjustments</li> <li><a href="/facts/Frame_rate/sbRkc9xa">frame rate</a> conversion and <a href="/facts/IVTC/TfB3cWqL">inverse-telecine</a></li> <li>color point conversion (601 to 709 or 709 to 601)</li> <li><a href="/facts/Color_space/zFvEyfHv">color space</a> conversion (<a href="/facts/YPbPr/re8FpvzL">YPBPR</a>/<a href="/facts/YCbCr/gfQaSqUA">YCBCR</a> to <a href="/facts/RGB_color_model/3Be0zwCj">RGB</a> or RGB to YPBPR/YCBCR)</li> <li><a href="/facts/Compression_artifact/7DhxoVAv">mosquito noise</a> reduction</li> <li><a href="/facts/Compression_artifact/7DhxoVAv">block noise</a> reduction</li> <li>detail enhancement</li> <li><a href="/facts/Edge_enhancement/o7CIqhCt">edge enhancement</a></li> <li><a href="/facts/Motion_compensation/6BM2Ylxn">motion compensation</a></li> <li>primary and secondary color calibration (including hue/saturation/luminance controls independently for each)</li></ul> <p>These can either be in chip form, or as a stand-alone unit to be placed between a source device (like a DVD player or set-top-box) and a display with less-capable processing. The most widely recognized video processor companies in the market are: </p> <ul><li>Genesis Microchip (with the FLI chipset – was Genesis Microchip, STMicroelectronics completes acquisition of Genesis Microchip on January 25, 2008)</li> <li>Sigma Designs (with the VXP chipset – was Gennum, Sigma Designs purchased the Image Processing group from Gennum on February 8, 2008, Sigma Designs is now part of Silicon Labs)</li> <li>Integrated Device Technology (with the HQV chipset and Teranex system products – was Silicon Optix, IDT purchased SO on October 21, 2008, IDT is now part of Renesas)</li> <li><a href="/facts/Silicon_Image/pVNYHdll">Silicon Image</a> (with the VRS chipset and DVDO system products - was Anchor Bay Technologies, Silicon Image purchased ABT on February 10, 2011)</li></ul> <p>All of these companies' chips are in devices ranging from DVD upconverting players (for Standard Definition) to <a href="/facts/HD_DVD/ULvpqYxb">HD DVD</a>/<a href="/facts/Blu-ray_Disc/zyPalhfG">Blu-ray Disc</a> players and set-top boxes, to displays like plasmas, <a href="/facts/Digital_Light_Processing/jxMs8emm">DLP</a> (both front and rear projection), <a href="/facts/Liquid_crystal_display/8B6xGBEz">LCD</a> (both <a href="/facts/Liquid_crystal_display_television/k6YB3J0k">flat-panels</a> and <a href="/facts/LCD_projector/lD8umEBw">projectors</a>), and <a href="/facts/LCOS/r65bD7X4">LCOS</a>/"<a href="/facts/SXRD/b3HlG62k">SXRD</a>". Their chips are also becoming more available in stand alone devices (see "External links" below for links to a few of these). </p> <ul><li>Bovik, Al (ed.). <i>Handbook of Image and Video Processing</i>.
