Judgement of Position Displacement and Subsequent
Measurement
Judgement
OK
Measurement is performed after position displace-
ment compensation.
NG
Measurement is performed without position dis-
placement compensation. Output to the OR termi-
nal is NG, irrespective of measurement result.
Unless a difference in density that is greater
than the set level is detected, position dis-
placement compensation will not be per-
formed. The judgement will be NG.
Register an image pattern (the "model") in advance. The part
of an input image that is most similar to the model is found,
and the displacement of its position from that of the reference
position is obtained.
