# Gamma Corrector

## Description

Gamma correction is a method used to adjust images or video frames to counteract the non-linear behavior of display
systems, such as cathode ray tube (CRT) displays. CRT displays have a characteristic where the intensity they produce
is not directly proportional to the input voltage. Instead, the intensity is related to the signal amplitude raised to a
power, known as gamma. Typically, gamma is greater than 1, meaning these displays have lower gain at low
intensities and higher gain at higher intensities. Lattice's Gamma Corrector IP core compensates for this by multiplying
the input signal with the inverse of the display's transfer function, resulting in a linear intensity response relative to
the original input signal.
