WebGamma correction is a technique used to compensate for the non-linear display characteristics of a device. Gamma correction is achieved by mapping the input values through a correction function, tailored to the characteristics of the display device, before sending them to the display device. WebThe gamma correction is an image-processing algorithm that compensates for the nonlinear effect of signal transfer between electrical and optical devices. The image processing performed by video applications, such as CRTs, digital cameras, color printers, and scanners, includes a gamma correction for the output.
