Gamma Adjustment

When the gamma curve is a straight line:
The brightness and contrast of the video input will be the same as that of the video output.

Area for which the gamma curve is above the straight line (A):
Video output appears brighter than the input.

Area for which the gamma curve is below the straight line (B):
Video output appears darker than the input.

Area for which the slope of the gamma curve is steep (midtone) (C):
The grayscale range of the video output becomes wider, and the contrast increases (D D’).
