[clarification needed] Therefore, turning on the G and B of one pixel and the R of the next pixel to the right will produce a white dot, but it will appear to be 1/3 of a pixel to the right of the white dot that would be seen from the RGB of only the first pixel. Subpixel rendering takes advantage of this to provide three times the horizontal ...
In addition, the graphics processing unit (GPU) provides an efficient way to scale the video in size and often performs color-format conversions (such as MPEG-2's YCbCr into RGB). An application using a hardware overlay gets a completely separate section of video memory that belongs only to that application.
The graphics chip internally can power up on either the rising or falling edge of the clock, so the bit patterns that represent orange and blue are not predictable. Most CoCo games start with a title screen and asks the user to press the reset button until the colors are correct.
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite .
In theory, the method (called "RGB Decimation" internally) can enhance the anti-aliasing of any digital image. [3] ClearType was invented in the Microsoft e-Books team by Bert Keely and Greg Hitchcock. It was then analyzed by researchers in the company, and signal processing expert John Platt designed an improved version of the algorithm. [4]
The Enterprise computer has five graphics modes: 40- and 80-column text modes, Lo-Res and Hi-Res bit mapped graphics, and attribute graphics. Bit mapped graphics modes allow selection between displays of 2, 4,16 or 256 colors (from a 3-3-2 bit RGB palette), but horizontal resolution decreases as color depth increases.
The variable-bitrate is actually a way to temporarily disable the display link; [7]: 125 it only adds the possibility of choosing 0 bit/px. [ 7 ] : 41 Repeating recent pixels can be stored in 32-entry Indexed Color History (ICH) buffer, which can be referenced directly by each group in a slice; this improves compression quality of computer ...
Older, cheaper, or faster LCDs, especially those using TN, often represent colors using only 6 bits per RGB color, or 18 bit in total, and are unable to display the 16.78 million color shades (24-bit truecolor) that contemporary signal sources like graphics cards, video game consoles, set-top boxes, and video cameras can output.
