8-5 Black Level Calibration
Black level calibration does t w o things:
1. It sets the black level of the camera to ensure that, in the absence of all light, there is no o ff set or
clipping (the “blackest” pixel will have a value of 0).
2. Dark frame data is saved for correcting Fi x ed Pa tt ern Noise (FPN).
NOTE: Fixed Pa tt ern Noise exists on every image sensor.
Calibrate Black Level:
The general rule is to do a Black Level Calibration if e ver you believe the image looks noisy with Pixel FPN
turned on. To be assured that you are getting the b es t possible images, perform a calibration
• When you fi r st boot the camera up.
• If you change Shu tt er Speed, Frame Rate,
Resolution, or O ff set.
To Calibrate the Camera
1. Set the camera to Live.
2. Shut out all light to the sensor: close the f-stop
down all the way and put a lens cap on it or cover
it securely.
3. From the Configu r ation menu, choose Black L e vel
Calibration
4. In the Advanced Settings section of th e r ecord
Settings T ab (see Figure 8-1 on page 62) you will
see an FPN selection d r opdown menu. The items include Disabled Column, or Pixel. Click on that
bu tt on and select the FPN setting ou wish to use, based on the following:
• Pixel FPN is a per-pixel image correction th a t is done in the TS3’s image processor engine. It
provides the cleanest images available. This is the setting t ha t is most highly recommended.
• Column FPN
is an image correction done on the T S3’s sensor. It does not do as good a
job cleaning up the images as Pixel FPN.
• FPN Off means that there is no noise correction being used.
