GammaAnpassung

GammaAnpassung, also known as gamma correction, is a technique used in digital imaging to adjust the brightness and contrast of an image. It is named after the gamma function, which describes the relationship between the linear intensity of light and the perceived intensity. The purpose of gamma correction is to compensate for the non-linear response of display devices, such as monitors and televisions, to ensure that the colors and brightness levels in an image are accurately represented.

In digital imaging, gamma correction is typically applied to raw image data before it is displayed. The gamma value, which is usually between 0.45 and 2.2, determines the degree of correction. A lower gamma value increases the brightness of the darker areas of an image, while a higher gamma value increases the brightness of the lighter areas. The most common gamma value used in digital imaging is 2.2, which is the standard for most computer monitors.

Gamma correction is an essential step in the image processing pipeline, as it ensures that the colors and brightness levels in an image are accurately represented on a display device. Without gamma correction, images may appear too dark or too bright, and the colors may not be accurately represented. Gamma correction is used in a wide range of applications, including photography, video production, and computer graphics.
