7.3 Camera Configuration
P
Recording lines:
It is possible to adjust the recorded lines before and after triggering when using a photo-
cell. This adjustment is very important for many sports in order to obtain a picture of the
whole competitor.
Recording lines <before> recommendation for most sports: 140 pixels
Recording lines <after> recommendation for most sports: 100 pixels
Q Motion detection:
It is possible to execute the automatic picture recording by changes in the picture. In or-
der to get the best possible result it is possible to make some adjustments.
Area of the sensor that you want to check:
Adjust the area of the sensor that you want to use for recording. Therefore it is neces-
sary to adjust the pixels used for recording. Often you do not want to use the lower or
upper pixels, since there is something unstable in the picture (e.g. spectators or flags
that move). The sensor has 1360 vertical pixel. The counting starts with pixel 1 on the
bottom and ends with pixel 1360 on the top.
<Check to pixel (<1360
)
: Top pixel that you want to use for the movement recognition
<Check from pixel (>1):
Bottom pixel that you want to use for the movement recogni-
tion
<Diff. value (10)>:
Fine tuning for motion detection. A good reference value is
10 (works very well in most conditions). The lower you go
with the <Diff. value>, the more sensitive the recording gets
(less pixel changes).
<Threshold (12)>:
Fine tuning for motion detection. This value you should
change only if you have big problems. In general keep the
<Threshold> on value 12.
