This adjustment is performed for an inspection head.
The inspection head judges an inspection result by using colors and brightness of images captured by the
color camera.
Adjustment of white balance is a function to calibrate the camera to the normal condition so that the
inspection head can perform inspection correctly.
The calibration board and user master board are used for adjusting white balance. On the machine side,
colors and brightness of the camera is calibrated by using the calibration board. Because colors and
brightness of the calibration board itself change due to such as dust on the surface or deterioration with age,
it can also be calibrated by the user master board.
Therefore, when you adjust white balance, a target value of the calibration board must be obtained as well.
This operation is performed only on the inspection head.
