X64 Xcelera-CL PX4 User's Manual CamExpert Quick Start
•
39
•
Click Grab to start live acquisition.
•
Aim and focus the camera. The camera should see an area of white or place white paper in front
of the object being imaged.
•
Click on one of the four Bayer pixel alignment patterns to match the camera (best color before
calibration). Typically the CamExpert default is correct for a majority of cameras.
•
Adjust the lens iris to reduce the exposure brightness so that the white image area is now darker.
Make certain that no pixel in the white area is saturated.
•
Using the mouse left button, click and drag a ROI enclosing a portion of the white area.
•
Click on the Auto White Balance button. CamExpert will make RGB gain adjustments.
•
Open the camera iris to have a correctly exposed image.
•
Review the image for color balance.
•
Manually make additional adjustments to the RGB gain values. Fine tune the color balance to
achieve best results. Adjust the gamma factor to additionally improve the display.
•
Stop the live acquisition and save camera file (which now contains the Bayer RGB calibration
information). Note that the gamma factor is not save because it is not a Sapera parameter but
only a display tool.
Using the Bayer Filter
A Sapera application, when loading the camera file parameters, will have the RGB gain adjustment
values. The application can provide the calibration window to make RGB adjustments as required.
