Gamma correction or gamma is a nonlinear operation used to encode and decode ... With Microsoft Windows 7 and above the user can set the gamma correction through the ...
Colors are stored in sRGB colorspace but drawing functions take into account gamma correction. There are many color manipulation functions such as shifting colors and colorizing. [14] [13] Since version 6, there is a curve adjustments function on RGBA channels and according to a corrected HSL colorspace. [15]

The sRGB standard defines the chromaticities of the red, green, and blue primaries, the colors where one of the three channels is nonzero and the other two are zero.The gamut of chromaticities that can be represented in sRGB is the color triangle defined by these primaries, which are set such that the range of colors inside the triangle is well within the range of colors visible to a human ...
Most digital cameras have means to select color correction based on the type of scene lighting, using either manual lighting selection, automatic white balance, or custom white balance. [6] The algorithms for these processes perform generalized chromatic adaptation. Many methods exist for color balancing.
Gamma correction is particularly useful for bringing details that would be hard to see on most computer monitors out of shadows. In some image editing software, this is called "curves", usually, a tool found in the color menu, and no reference to "gamma" is used anywhere in the program or the program documentation.
Interpolation and Gamma Correction In most real-world systems, gamma correction is required to linearize the response curve of the sensor and display systems. If this is not taken into account, the resultant non-linear distortion will defeat the purpose of anti-aliasing calculations based on the assumption of a linear system response.
On a typical standard 2.2-gamma CRT display, an input intensity RGB value of (0.5, 0.5, 0.5) only outputs about 22% of full brightness (1.0, 1.0, 1.0), instead of 50%. [19] To obtain the correct response, a gamma correction is used in encoding the image data, and possibly further corrections as part of the color calibration process of the device.
