CALIBRATION

Sensor calibration is a process where the camera generates a calibration map to correct for pixel

defects and offsets based on current system and environmental settings. This allows you to perform a

Black Shading calibration of the MYSTERIUM X sensor two (2) different ways; Default (at 24 FPS @ 1/48

SEC) or using your current FPS/Exposure settings.

To calibrate the sensor the image needs to be as dark as possible:

• At a minimum put a lens cap on the lens (WARNING: Not all lens-caps completely block IR. They are

made to protect the lens, not necessarily to block light...)

• Preferably, take of the lens, and use the lens-mount cap provided by RED.

• If possible, use a dark room.

• Just closing the Iris is NOT sufficient.

Additionally a SSD needs to be inserted in the camera to store the raw images during calibration.

Calibration is required:

• If the temperature deviates significantly from the currently used calibration, it is recommended to

recalibrate the sensor.

• If very long exposure (~longer then 1/24 Sec) is used it is recommended to recalibrate.

After Calibration with a lens cap on and ISO set to maximum, the sensor should show a uniform noise

profile over the whole area without any falloffs on any side. You can check at which

temperature/exposure time the currently used calibration was taken on under SETTINGS >

MAINTENANCE > SYSTEM STATUS under Calibration.

Calibration maps will still be available after performing a system restore under SETTINGS >

MAINTENANCE > RESTORE SYSTEM; however the factory calibration map will be reselected.
