Spectroradiometer measurements can be captured in any order but all three x, y, and fL
measurements must be entered before moving onto the next capture. You can recapture a
specific measurement at any time during the process by selecting the Capture button. In
this case, the measured spectroradiometer and color sensor values are reset.
d) Once all the color sensor and measured values are entered for all nine rows, select Apply
and Save.
7. Verify and complete the calibration.
a) Select a white point to measure by selecting either the DCI, D65, or Custom white point
buttons.
Once selected, the projector automatically enables LiteLOC, selects a White test pattern
with uncorrected colors at the white point specified, and sets the brightness to 80%.
b) Using a spectroradiometer, measure screen x and y values at the center of the screen.
To verify the calibration has been successfully applied, the measured white point must be
within the expected tolerance.
c) When complete, select Finish.
The projector output is configured according to the currently selected calibration file and
you are returned to the Sensor-to-screen Calibration menu.
Editing the existing calibration file parameters
Make corrections to the existing calibration file parameters, when the values from the
spectroradiometer were entered in error.
1. Select Menu > Color Settings > Sensor-to-screen Calibration.
2. Select a user-defined calibration file.
3. Edit any of the x, y, or fL values by selecting the field under Measured Values and using the
numeric keypad to enter the updated value.
•
x and y value range: 0.0001 to 0.9999
•
fL value range: 0.01 to 9999.99.
4. To save the updated file to the projector, select Save.
Verifying the sensor-to-screen calibration
Check the integrity of the calibration, if required.
1. Navigate to Menu > Color Settings > Sensor-to-screen Calibration.
2. Select the White test pattern.
3. Select Verify Calibration.
If the douser is closed and/or the light source is off, a dialog is displayed informing the user
that the douser must be open and the light source turned on before verification can occur.
Step 3 of the Calibration wizard opens.
4. Verify and complete the calibration.
a) Select a white point to measure by selecting either the DCI, D65, or Custom white point
buttons.
Once selected, the projector automatically enables LiteLOC, selects a White test pattern
with uncorrected colors at the white point specified, and sets the brightness to 80%.
