[1] Camera position adjustment
This function facilitates adjustment of the camera position and direction with respect to the object
being measured and the lens aperture when a camera is replaced or when a camera is dislocated. By
using this function, you will need not to adjust the settings for the measurement conditions, such as the
window position, one by one.
(1) Adjusting method
Differences in size, position or brightness between two binary images, before and after a camera is
replaced or a camera is dislocated, will be displayed as a white image.
When the adjustment is complete, the image is displayed as black.

To make a fine adjustment, the camera position can be adjusted by comparing the fillet diameters,
centers of gravity, and average light levels before and after a camera is replaced or a camera is
dislocated.
