Shortening the Processing Time
Shortening the imaging processing
time
z z Imaging Area
The processing time can be shortened by
adjusting the imaging area.
Entire imaging area (default value)
Reduce the imaging area
Non-imaged area
Reduce the imaging area by setting the imaging
area from Entire (default value) to Partial. The
processing time for capturing the image in Non-
imaged area can be shortened. The importing
time will be shortened by narrowing the vertical
direction (V).
“Imaging Area” (Page 4-17)

Exposure Time
The processing time can be shortened by
shortening the exposure time (Page 4-18). The
longer exposure time makes the processing
time longer than the displayed exposure time.
By unmounting the dome attachment or
polarizing filter attachment, the exposure time
can be shortened.
Selecting the tool
The processing time of the Color Area/Area tool
will be shorter than the Outline tool. Therefore, you
should select the Color Area/Area tool whenever
possible.
Shortening the processing time of
each tool
Shortening the processing time of the
Outline tool
The processing time can be shortened by adjusting
the settings for the search region, rotation range,
and search algorithm.
Search region
Rotation range
z z Search Region
The searching time can be shortened by
reducing the search region and setting the
region from [Entire] (default value) to [Partial].
Make sure that the range of position determining
of the target does not exceed the search region.
“Setting a search region” (Page 4-35)
z z Rotation Range
The target search time while rotating the master
image can be shortened by reducing the rotation
range (default value: ± 20°).
Make sure that the range of an installation angle
of the target does not exceed the rotation range.
“Rotation Range” (Page 4-38)
z z
Search Algorithm
Select the [High Speed]. This will decrease the
judgment accuracy, but the processing time will be
shorter.
“Search Algorithm” (Page 4-38)

Producing an image with less unwanted
outlines
The processing time becomes longer for images
with multiple unwanted outlines other than the
target outlines.
y Make an image with no unwanted outlines by
making the target background plain, etc.
y Set the search region so that non-target images
containing unwanted outlines are not searched.
