RightLight Service
The RightLight service performs backlight stabilization,
DICOM calibration, automatic conformance testing, and manual
conformance testing via an external photometer for Dome Cx,
Dome Ex, Dome GX4MP, and Dome Sx displays. Manual conformance
testing via the display front sensor is available for Dome Sx units.
With RightLight, you can set a target white level, equalize the black
level across the displays, set a desired response function, and specify
ambient light in the viewing area. This service also reports current
white and black levels.
RightLight automatically calibrates the displays at regular intervals.
Calibration adjusts the response of a display to conform to the
response function you specify. There are four calibration response
functions, one of which is a correction to the DICOM Grayscale
Standard Display Function.
DICOM calibration is based on the unique characteristic curve stored
in each display at the time of manufacturing. RightLight routinely
checks how well each display conforms to the DICOM standard and
calculates a Luminance Uniformity Metric (LUM) value that indicates
the degree of conformance.
Besides the automatic conformance testing and adjustment that
RightLight performs regularly, you can perform manual external
sensor conformance testing, using an optional photometer. On
Dome Sx displays, you can also perform manual conformance testing
with the embedded front sensor photometer.
