Image 9–1 Shifting projector 'white point' towards desired white point (laser power calibration)
The projector uncorrected white point can be defined by measuring the xy coordinates of the uncorrected
primary colors (red, green, blue) and uncorrected full white separately.
The initial set of xy values stored in the projector for the uncorrected white point are the same as for DCI white
point. After white point calibration, the initial values are overwritten with the measured values.
Based on the measured values the projector can balance the power of the lasers for Red, Green and Blue to
move the projector uncorrected white point towards the desired white point. This adjustment is called 'Laser
RGB correction' or "Light Source calibration".
The projector uncorrected white point is different for 2D projection and 3D projection. Therefore, the projector
uncorrected white point has to be measured and entered for each projection mode separately. Per projection
mode one set of measured values are stored. Depending on the projection mode, the corresponding set is
used for white point correction.
In case of 3D projection, the xy coordinates of uncorrected white has to be measured for each 3D file
separately.
Overview
This menu allows you to perform a white point calibration.
