A 15-pin VGA connector for a personal computer A 21-pin SCART or JP21 connector for a television. The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of ...
YPbPr or Y'PbPr, also written as YPBPR, is a color space used in video electronics, in particular in reference to component video cables. Like YC B C R, it is based on gamma corrected RGB primaries; the two are numerically equivalent but YP B P R is designed for use in analog systems while YC B C R is intended for digital video. [ 1]
YCbCr. A color image and its Y′, C B and C R components. The Y′ image is essentially a greyscale copy of the main image. YCbCr, Y′CbCr, or Y Pb/Cb Pr/Cr, also written as YCBCR or Y′CBCR, is a family of color spaces used as a part of the color image pipeline in video and digital photography systems. Y′ is the luma component and C B and ...
An image along with its Y′, U, and V components respectively. Y′UV, also written YUV, is the color model found in the PAL analogue color TV standard (excluding PAL-N ). A color is described as a Y′ component ( luma) and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input ...
Gamma correction is, in the simplest cases, defined by the following power-law expression: where the non-negative real input value is raised to the power and multiplied by the constant A to get the output value . In the common case of A = 1, inputs and outputs are typically in the range 0–1. A gamma value is sometimes called an encoding gamma ...
1 RCA, BNC, TV Aerial Plug, Mini-VGA, DIN 5-pin, [ 2] SCART 21-pin. Analog. 576 lines tv compatible. 625 lines tv compatible. Consumer electronics, including VCR and LaserDisc, 1970–1980s home computers like the VIC-20, 1980s–1990s video game consoles, some laptops, some single-board computers like the Raspberry Pi.
The RGB color model is an additive color model [ 1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. [ 2]
The subsampling scheme is commonly expressed as a three-part ratio J:a:b (e.g. 4:2:2) or four parts, if alpha channel is present (e.g. 4:2:2:4), that describe the number of luminance and chrominance samples in a conceptual region that is J pixels wide and 2 pixels high. The parts are (in their respective order):
