| | Pixel - encyclopedia article about Pixel. |
 | | Pixels on computer monitors are usually square, but pixels used in digital video Digital video is a type of video recording system that works by using a digital, rather than analog, representation of the video signal. | | | In computer programming, an image composed of pixels is known as a bitmapped image or a raster image raster graphics image, digital image, or bitmap, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computer monitor, paper, or other display device. | | | An example of a technology that uses the latter approach is the use of colour fringing on computer fonts to encode sub-pixel resolution luminance information. |

| | United States Patent: 5,751,272 |
| | The elongation of the pixel structure has resulted in a distancing of optical centres of illumination in the column direction at the expense of a shortening of the distance between optical centres in a row direction. | | | This preferred pixel arrangement of maximising the distance between the optical centres of neighbouring sub-pixels in column direction is of significant importance in reducing unwanted artifacts in images as a result of any movement of optical centres. | | | Additionally, the optical centre of red sub pixel 15 is further away from the optical centre of the red sub pixel 17. |

| | This is shown in the schematic above, which represents a 30x30 pixel CCD with a 4x4 pixel subarray (shown in blue). | | | Unfortunately, the drawback is that it will be flat at the level of the highest pixel in the frame, plus any software latency. | | | The consequences of this include smearing of the star images down columns and a higher background due to the extra exposure each pixel will have while the CCD is being read. |

| | In their most common computer application, notebook computers, video drivers take the digital information in the graphics frame buffer and digitally interface to the row and column drivers that set the colors at each pixel in the display. | | | In storage, pixels are made up of one or more bits. | | | If there is a slight error in the clock, this error accumulates as the line is scanned from the left to the right edge of the display. |

| | Technical Overview of ClearType Filtering |
| | One approximation to the optimal ClearType filters is to have the output sub-pixel only depend on pixels of the same color in the input image. | | | For example, the red sub-pixels value is the result of applying the red filter to the red channel of the input image. | | | This approximation consists of only three out of the original nine filters: a red filter, a green filter, and a blue filter. |

| | How Sub-Pixel Font Rendering Works |
| | As a computer user you've probably noticed that sometimes 'bold' seems too bold (way more than it should be) and at other times it doesn't seem to do very much at all. | | | Since sub-pixel rendering depends heavily upon the physical proximity of adjacent sub-pixels, the rendering algorithm must know whether the pixels are ordered Red-Green-Blue or Blue-Green-Red. | | | Suppose we wish to draw an object with a sloping diagonal edge. |

| | Description of ClearType Font Smoothing Technology in Windows XP |
| | ClearType is a form of sub-pixel font rendering that draws text using a pixel's red-green-blue (RGB) components separately instead of using the entire pixel. | | | Sub-pixel font rendering takes advantage of this by antialiasing at the sub-pixel level instead of at the pixel level. | | | The human eye is not capable of differentiating colors on such a small scale, so a combination of these three primary colors can emulate any intermediate color. |

| | Anti-aliasing - Wikipedia, the free encyclopedia |
| | Mipmapping works by creating lower resolution, prefiltered versions of the texture map. | | | Indeed, an ordinary computer screen has no more than a few million pixels, and each pixel only has a finite number of colors it can display. | | | Since this requires that the primitives be in some order, and hence interacts poorly with an application programming interface such as OpenGL, the latest attempts simply have two or more full sub-pixels per pixel, including full color information for each sub-pixel. |

| | Dealing with Dead Pixels |
| | Of course, if you need a test program to determine if you have a dead pixel, any problem you have in this context can't be too serious. | | | This is true of all portable computers using LCD technology, not just the PowerBook." | | | Apple says that a pixel becoming stuck either on or off is known as a "pixel anomaly," and that it considers a small number of such anomalies to be acceptable. |

| | Well, consider that for every pixel, you're actually storing 2 sub-samples. | | | So, now, you're storing 2x the data for every pixel, so the frame-buffer is twice as big. | | | Also, in terms for frame-buffer use, each chip works out to holding a complete frame-buffer. |

| | Coupled with the latest e-book reading software and hardware, this provides an on-screen reading experience that begins to rival paper. | | | Microsoft has developed a font display technology called ClearType that, by manipulating the red, green and blue sub-pixels that make up the pixels on an lcd screen, improves resolution by up to a factor of three. | | | Most typefaces were not designed for screens and, thanks to a limited number of pixels, are just fuzzy reproductions of the originals. |

| | For example, at about 6" from your display, assuming you're not far sighted, you should easily be able to see the pixelization, i.e., the jaggies with globs of techno-colored grays, in the above XP or OS X samples of text. | | | It also may depend on your preference for seeing details over your aversion to seeing pixelization. | | | Now of course, perceptions of text rastering are highly subjective and depend on several factors, not the least of which are the quality of your sight and monitor and the distance you sit from your display. |

| | (57) Image data processing and image rendering methods and systems whereby images (210b) are displayed on display devices (208) having pixels with separately controllable pixel sub-components (R, G, B). | | | The displayed advance width of a character (214b) displayed with sub-pixel precision is compatible with the advance width of the character (214b) if it had instead been displayed with a conventional full pixel precision rendering process. | | | Thus, characters (214b) are displayed with sub-pixel precision, resulting in improved resolution and readability, while the advance width and the corresponding size and spacing of the characters (214b) and the overall formatting (206a) of the document (210b) remains the same compared to documents and characters rendered using conventional full pixel precision processes. |

| | Flat Panel Monitors... Replicating the Look of Film |
| | LCDs have a structure within each sub-pixel that is the control circuit. | | | When activated, the TFT goes to a low resistive state permitting the video reference voltages to be applied to the LCD row and then switch to a high resistive state to lock that potential into the sub-pixel until the next command (refresh rate). | | | A monochrome CRT-based display has the least structure of the available technologies, but there are limits to a CRT performance that an AM-LCD (Active Matrix – Liquid Crystal Display) can leap over. |
