Pixel - Wikipedia, the free encyclopedia |
 | | The intensity of each pixel is variable; in color systems, each pixel has typically three or four dimensions of variability such and red, green and blue, or cyan, magenta, yellow and fl. |
 | | Pixels on computer monitors are usually square, but pixels used in digital video have non-square aspect ratios, such as those used in the PAL and NTSC variants of the CCIR 601 digital video standard, and the corresponding anamorphic widescreen formats. |
 | | The technique, referred to as subpixel rendering, uses knowledge of pixel geometry to manipulate the three coloured sub-pixels separately, and is most effective with flat-panel displays set to their native resolutions (because the pixel geometry of such displays is usually fixed and predictable). |
