Pixelplus, also called Pixel Plus, is a proprietary digital filter image processing technology developed by Philips which they claim "enhances" the display of analogue broadcast signals on their TVs. Proprietary indicates that a party, or proprietor, exercises private ownership, control or use over an item of property, usually to the exclusion of other parties. ... An FIR filter In electronics,nirali a digital filter is any electronic filter that works by performing digital mathematical operations on an intermediate form of a signal. ... UPIICSA IPN - Binary image Image processing is any form of information processing for which the input is an image, such as photographs or frames of video; the output is not necessarily an image, but can be for instance a set of features of the image. ... Philips HQ in Amsterdam Koninklijke Philips Electronics N.V.

See TV (disambiguation) for other uses and Television (band) for the rock band European networks National In much of Europe television broadcasting has historically been state dominated, rather than commercially organised, although commercial stations have grown in number recently. ...


Pixelplus interpolates the broadcast signal to increase the picture size by one third, from 625 lines to 833 lines. It also "doubles" the horizontal resolution, although each horizontal line is analogue. In the mathematical subfield of numerical analysis, interpolation is a method of constructing new data points from a discrete set of known data points. ...


Other features that may be unique to Pixelplus include motion interpolation, a processing technique that introduces (or reintroduces) a higher rate of motion into the video the TV is given. This can create an effect of 50 frames per second where 25 existed, or 60 where 30 existed, or 60 where 24 existed. Typically this is used for film-based material that was originally delivered in 24 or 25 frames per second, whereas the display is capable of far more fluid, realistic motion. Note that a broadcast may be 720p50 but still carry 720p25 material, for instance. Frame rate, or frame frequency, is the measurement of how quickly an imaging device can produce several consecutive images, called frames. ...


In 2005, Pixelplus 2 was launched. This version was the first to be able to perform motion reinterpolation on 480p and 576p material. 480p is the shorthand name for a video mode. ... 576p is the shorthand name for a video mode. ...


In 2006, Pixelplus 3 was launched. This version was the first to be able to perform motion reinterpolation on 720p and 1080i material. 720p is the shorthand name for a category of HDTV video modes. ... 1080i is shorthand name for a category of video modes. ...


In 2007, Pixel Perfect HD was launched. This version was the first to be able to perform motion reinterpolation on 1080p material. 1080p is the shorthand name for a category of video modes. ...


There are now several webcams that have this technology. Its optics are so sensitive that it gives high definition images in the dark.
