Camera Calibration

•

Prepare for Calibration

For best results, the camera should be setup for calibration with similar conditions as to

those in which it will be used. For example, data mode, exposure times and line rates, scan

direction, etc.

For example, set the color gain for the current color using the

Color Gain

command.

Step 1: White Balance Calibration

Remove the lens cap and prepare a white, uniform target.

Adjust the line rate so that the average output is about 80% of the full output by:

adjusting the lighting, if you are using an internal exposure mode. Or, adjust the line

rate, if you are using the Smart Exsync mode.

White balance calibrates individual colour gain settings so that the outputs are equal

between the colors. Calibrate the white balance using the commands

Calibrate White

Balance Target

and

Calibrate White Balance

, where the target value (always

counted as 12-bit) is 1024 to 4055 DN. For example, if you want to set the target to

255 x 80% = 204 DN in 8-bit mode, then the target value is (204/255) x 4096 = 3277

DN in 8-bit mode. Therefore, you can set the target to 3300 DN.

Calibration results from the Calibrate White Balance command:

•

Success

•

Clipped to min > Color gain set minium, failure to reach target

•

Clipped to max > Color gain set maximum, failure to reach target

•

Timeout > FPGA did not return new end of line statistics or video line

Step 3: FPN Calibration

Note that you do not need to turn off the FPN and PRNU coefficients before calibrating, the

camera will do this automatically.

Stop all light from entering the camera. The best way to do this is to put on lens cap.

Calibrate FPN using the

FPN Calibrate

command.

Use the

Read FFC Calibration Result

parameter to determine if your calibration was a

success or not.

To save the calibrated FPN coefficients to the FFC coefficient set shown, use the

Set

FPN Save

parameter.

Step 4: PRNU Calibration: White Calibration

Performs PRNU calibration to user entered value and eliminates the difference in

responsivity between the most and least sensitive pixel creating a uniform response to light.

Using this command, you must provide a calibration target.

Executing these algorithms causes the

Background Subtract (DN)

value to be set to 0

(no background subtraction) and the

Digital Gain (DN)

value to 4096 (unity digital gain).

The pixel coefficients are disabled (

Pixel Set Load 0

) during the algorithm execution but

returned to the state they were prior to command execution.

Remove the lens cap and prepare a white, uniform target.

Adjust the line rate so that the average output is about 80% of the full output by:

adjusting the lighting, if you are using an internal exposure mode. Or, adjust the line

rate, if you are using the Smart Exsync mode.
