gammakõverit
Gammakõverit, often translated as gamma curves or gamma correction, are a concept used in image processing and video systems to describe the relationship between the pixel values and the luminance of a display. In essence, it's a way to encode and decode brightness information. A display device's response to an electrical signal is not linear; the relationship between the input signal (voltage) and the actual light output (luminance) is typically non-linear, often following a power-law function. This non-linear behavior is what gamma correction aims to address.
When images are captured or created, they are often done so with a specific gamma value in
