1: pixel gray level < threshold level,
trigger line not visible
2: pixel gray level > threshold level,
trigger line visible
3: pixel gray level < threshold level,
trigger line visible
Response:
none
The trigger line is displayed as dashed, black and white line. One dash has a length of 10 pixel. The
trigger line is only displayed in parts of the line where the pixel fulfill the trigger requirements.
Under normal operation conditions the trigger line will be visible only in parts. The number of dashes
may be counted and used for the setting of register rB
h
.
6.17.2.5 Release condition
Register rB
h
contains the release condition.
The release condition is determined by the number of pixels along the triggerline that fulfill the trigger
requirements.

6.17.2.6 Release Inhibit
The Release Inhibit function is defined with :rD
h
. It tells ImageBLITZ how often sequentially the “re-
lease condition” must
not
be met, before an image is output.
This feature allows to trigger an object only once on the dark- to bright edge of the scene. This avoids
retriggering, once the trigger condition was met and the object is still visible within the triggerline after
the image has been output.
Command:
:rD
