Flexible Search
Specify a larger value for the "Prec."
If the measurement results are unstable only when "Rotation" is selected, specify a smaller value
for the "Skipping angle".
When "Rotation" is selected, if the model shape is complex, uncheck the "Smart mode" option.
If the image has low contrast or blurred edges, set the "Search mode" to "CR".
If the model image consists of detailed figures, specify a larger value for "Stab."
If the precision is low, place a check at "Sub-pixel".
If images that should be judged OK vary greatly, specify a smaller value for "Candidate LV".
If the model image is small and unstable, specify a smaller value for the "Reduction".
Make the search region as small as possible.
Bring "Stab." close to the factory default value.
Bring the "Skipping angle" close to the factory default value.
Specify a smaller value for "Prec.".
Make the search region as small as possible.
Make the area to register as the model as small as possible.
If the model image is a simple figure or a large figure, specify a smaller value for "Stab." If lowering
stability does not speed up processing, it is likely that many candidates have been detected. Raise
the "Candidate level" in [Measurement].
When "Rotation" is selected and the model image is a simple figure, specify a larger value for
"Skipping angle".
When "Rotation" is selected and the model image is a simple figure, place a check at "Smart
mode".
If the position precision is high, specify a smaller value for "Prec.".
If the rotation angle range is large, set the "Search mode" to "PT".
If images that should be judged OK vary little, specify a larger value for "Candidate level".
If the position precision is high, uncheck "Sub-pixel".
