Pixelplus, also called Pixel Plus, is a
proprietary digital filter image processing technology developed byPhilips which they claim "enhances" the display of analogue broadcast signals on theirTV s.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.
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.In 2005, Pixelplus 2 was launched. This version was the first to be able to perform motion reinterpolation on
480p and576p material.In 2006, Pixelplus 3 was launched. This version was the first to be able to perform motion reinterpolation on
720p and1080i material.In 2007, Pixel Perfect HD was launched. This version was the first to be able to perform motion reinterpolation on
1080p material.Not to be confused with Pixelplus Co., Ltd. (Nasdaq: PXPL) : a fabless semiconductor company in Korea that designs, develops, and markets CMOS image sensors for various consumer electronics applications.
