4.2.5.1.3 Perform a CSR, (Current Session Reference), Calibration Adjustment
Use CSR, (Current Session Reference, to calibrate the image for current Cine Settings parameters.
The Phantom Camera Control application will compute the offsets specific to the currently defined
parameters, obtaining a more precise compensation of the pixel errors. The CSR, (Current Session
Reference), processes is similar to Black Reference calibration adjustment.
Vision Research recommends that the CSR calibration adjustment process be performed before
recording a single cine configuration or a MultiCine configuration with all cine partitions having the
same acquisition parameters.
If the MultiCine partitions have different setup values, and the Advanced Settings>Auto Black
Reference option is not enabled because the camera does not employ an internal or external
automatic mechanical shutter, the end-user should perform a CSR calibration adjustment on each
cine partition separately, just before each cine is recorded
For details on the Automatic Shutter Lens Mount see: Accessories, Peripherals, and Miscellaneous
Features>Automatic Shutter Lens Mount Installation.
STEP-BY-STEP PROCEDURE
NOTE
Before performing a Current Session Reference Adjustment ensure that the EDR, Extreme
Dynamic Range), Exposure setting is set to zero, and the Auto Exposure and Image-Based
Auto-Trigger features are disabled.
Performing a Current Session Reference - Image Calibration
1.
Click the Live Control Panel Tab.
2.
Click on Cine Settings and define the following parameters prior to performing a CSR
calibration adjustment:
a.
Resolution,
b.
Sample Rate, and
c.
Exposure Time.
3.
Click on Camera Settings.
4.
Click the CSR button.
5.
If the camera does not have an internal or external automatic shutter mechanism, when the
Current Session Reference informational window instructing you to "Please, cover the camera
lens." appears, cover the lens with a lens cap to ensure the sensor is in complete darkness,
then
a.
Click the OK button to start the CSR calibration adjustment, alternately
b.
Click the Cancel button to cancel the CSR process.
NOTE
If the Phantom camera is equipment with either an internal or external auto-shutter the end-
user will not need to cover the lens with the lens cap as the sensor will be devoid of any
light by the auto-shutter mechanism.
