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 xed to the value dened by the particular preset’s standard (for example,
AdobeRGB species a xed 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)
specication. 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 specication. 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 specication that includes the offset, transition and slope
components.
• Custom - For custom response curves that do not t one of the above types. Custom curves can be created by
importing a list of numerical values from a plain text le. When imported, the values will be automatically scaled
and interpolated to create a custom gamma curve. The text le must conform to the following specications:
• Must contain between 3 and 256 values.
• Each value must be on a separate line.
• The rst value must be 0.
• Values must be monotonically increasing.
