■ Toggle with
<F5> between [Move] and [Resize] as necessary
■ Position and resize the area of interest with the arrow keys or by means of the
tracker ball and the scroll bars
The X and Y value indicate the centre of the search area with respect to the centre
of the BVM camera.
For fiducial-type badmarks:
■ Select
[Area of Interest]
The [Area of Interest] determines where the system will look for the badmark.
In this way “confusing” elements - like certain print patterns - can be avoided.
NOTE: It is recommended to make the area of interest not larger then necessary,
for a large area of interest will increase the time required for a meas-
urement.

The test results of the measurement will be shown in the [Status Badmark Meas-
urement]
box.
NOTE: Automatic teaching of a “ standard” badmark is only possible if both grey
levels (badmark and background) are visible in the [Area of Interest] (see
also the section Area of Interest). This implies that the camera must be
positioned slightly off-centre when the size of the badmark exceeds the
camera’s field of view.
NOTE: The automatic teach function of the badmark does not always supply
optimal results, especially for the grey level and threshold settings. If this
is the case, please refer to the section Light Level and Threshold for manual
teaching.
