<Threshold> edit box
The image viewed through the SM Vision window is composed of each pixel.
Each pixel has a unique value between 0 and 255 according to the seen degree of
brightness. Here, ‘Threshold Value’ indicates the border value deciding whether
each pixel should be recognized in white or black. That is, setup the limitation for
deciding if the image pixel should be black or white when checking a bad mark.
For example, if accept mark setup is “Black” and the <Threshold> value is 100, all
values under 100 in the vision image are recognized as black. And if <Accept
mark Logic> is “White” and the <Threshold> value is 100, all values over 100 in
the vision image are recognized as white.
<Real Display/Binary> button
Shows the image seen through the SMVision in real display to which threshold is
not applied, or in the image (Binary) to which threshold is applied as recognized
by MMI.
<Light> group
Set the lighting value when testing the Accept Mark. In general, set to 7. However,
adjust it properly according to the condition of the PCB and accept mark.
