Caution:
Incorrect settings of the normalization factor will provide
unsatisfactory results with arithmetic operations (i.e black or white
images).
•
The Add Live Images option enables up to 1000 consecutive live
images to be compiled into a single image.
•
The desired number of images can be selected under Options /
Addition Settings (see Figure 36).
Figure 36: Number of Images
This feature can also be used to reduce noise levels when recording
images or to reduce the resolution of moving objects, in comparison to
the background.
After the addition process the resulting picture is normalized so that
the original brightness is retained.
The length of the process depends on the number of images that were
added and the capability of the computer.
The operation’s status is displayed as a percentage in the lower section
of the window.
Caution:
In order to ensure that the brightness for added images has the same
quality as single images, the parameters for the number of images
change simultaneously with the normalization factor (type casting).
The normalization factor must eventually be re-configured when using
additional Arithmetic functions.
