6.4.4 Gamma
What can be adjusted ?
With the gamma correction adjustment, it is possible to accurately set the gamma of the projector image.
Gamma
The transfer characteristics of most cameras and displays are nonlinear. For a display, a small change in amplitude
when the signal level is small produces a change in the display brightness level, but the same change in amplitude at a
high level will not produce the same magnitude of brightness change. This nonlinearity is known as gamma. Different
gamma curves are available to compensate the nonlinearity.
Changing the gamma value
1. Push the cursor key ↑ or ↓ to highlight Gamma. (menu 6-35)
2. Press ENTER to select.
3. Change the gamma value by pushing the cursor key ← or → until the desired value is reached.
Note: Default value of gamma : 2.2
