3.1. Image Initialization (Calibration)
In order to maximize the high image quality of the system, it is necessary to correct the
non-uniformity in each pixel that is inherent in the image sensor.
For this product, an output correction of each pixel on the image sensor is adopted. Therefore, a
faithful image output can be obtained corresponding to the light input.
 In order to obtain faithful image output, execute calibration when the following settings are changed.
■ When the frame rate is changed
■ When the shutter speed is changed
■ When the resolution is changed
Also, depending on the settings, phenomena such as the following may occur.
■ Fixed noise, horizontal bands appear
■ A portion of the screen is clear, but noise appears in the area around it
These phenomena can be resolved by executing calibration again.
3.1.1. Executing Calibration
Calibration is executed from the "LCD remote controller (optional)" or from PFV.

For the procedure of performing this function, refer to "LCD Remote Controller User's Manual" or
"Photron FASTCAM Viewer User's Manual".
3.1.2. Saving Calibration Settings
The black image data for correction use that was obtained by executing the calibration can be saved
internally on the system.
3.1.3. Loading Calibration Settings
Saved black image data for correction can be loaded.
3.1.4. Calibration Mode
For this product, the calibration method can be changed by user. A NORMAL method and a FINE
method can be used.
