Display Gamma adjustment wizard page
The Display Gamma page is available with the High Brightness and Full presets, and Custom Picture Modes.
For all other Picture Modes the gamma is fixed to the value defined by the particular preset’s standard (for example,
AdobeRGB specifies a fixed gamma of 2.2).
The gamma of a display is the
relationship between the video input
signal level and the light output
(luminance or brightness) displayed
on the monitor.
The choice of gamma type and value will depend on the application.
Different types of Gamma responses can be selected:
•
Gamma Curve Value - The response curve will follow a simple gamma curve. Values between 0.5 and 4.0
can be entered. A gamma value of 2.2 is commonly used for most applications.
•
DICOM Curve - The response curve follows the DICOM (Digital Imaging and Communications in Medicine)
specification. This response curve is aimed at medical use, however it can be used for other applications. The
goal of the DICOM response curve is to have a visually linear display response.
•
L* Curve - A curve based on L* in the Lab specification. The L* curve is intended to be more perceptually
uniform than a simple gamma value curve.
•
sRGB Type Curve - A curve based on the sRGB specification that includes the offset, transition and slope
components.
•
Custom - Only available when emulating another display when the gamma response in the ICC/ColorSync
profile does not fit a simple gamma curve value.
