5.7.3.1.2.1 ImageBLITZ parameters
If ImageBLITZ is activated, the MotionBLITZ Cube camera compares the image detail
of the actual frame with the image detail of the reference frame. If the differences
within this image details exceed a limit, ImageBLITZ triggers (“releases”).
This two parameters for adjusting the ImageBLITZ may be set manually by entering
the values in the release parameters fields or automatically by clicking on “auto adjust”.
5.7.3.1.2.1.1 Pixel value difference
This parameter defines the absolute limit for the difference in the gray values within the
image details. The value range is 1 to 255.
With a small value small changings in the image detail let the ImageBLITZ trigger, with
a big value the ImageBLITZ trigger gets less sensitive. Under normal conditions, this
value should be between 10 and 70.
5.7.3.1.2.1.2 Relative object size
This parameter defines the relative size of the area within the ImageBLITZ window that
must be different from the reference frame before ImageBLITZ triggers. The value
range is 1 to 100 percent. If you use a small value, e.g. 5, then ImageBLITZ triggers
when 5% of the image details are different.
5.7.3.1.2.1.3 ImageBLITZ Reference frame
The ImageBLITZ reference frame is the first frame of a recording sequence, i.e. in Live
mode the first frame after starting Live, in record mode the first frame after starting the
recording. Using the auto adjust feature, the reference frame ist the next frame after
clicking on “auto adjust”
