MECHATRONICS TECHNOLOGY JAPAN Day 3

Another successful event today. We apologize for the inconvenience of running out of catalogs.
One of the questions we received today was, "Can the camera track ambient light?
The conclusion is that it cannot.
When inspecting with image processing, the only information available is the captured image, and it is not possible to distinguish whether the effect of ambient light entering the image is "caused by ambient light" or "caused by the object being inspected. Therefore, if "correction" is performed by treating the image as "disturbing light," there is a possibility that the image will be OK even if it is "caused by the object to be inspected. Therefore, in order to avoid the worst-case result of "leakage," it is our opinion that the correction of ambient light "should not be performed.
Basically, the concept of FI is based on the basic premise that "the same camera, same lighting, same lens, and same positioning will produce the same image. The only thing that can be corrected is the position correction of XYθ in relation to the camera, based on the assumption that the illumination conditions remain the same.
This was a bit of a heated discussion in the hall, but I hope you understand it as a point that we cannot compromise on.
# Incidentally, it is possible to deal with the influence of ambient light by enclosing it or by reducing the relative influence of ambient light by placing the camera in a stronger lighting environment than that of ambient light.
