11.9 Averaging
The avaraging feature lets you obtain an image that is the average of a set number of consecutively
acquired individual images. You can average up to 256 individual images.
When averaging is active, the pixel values for each pixel will be summed and the total for each pixel
will be divided by the number of the individual images acquired. Decimals of the resulting average
pixel values will be truncated and the averaged pixel values will be transmitted as integers.
You can use averaging for all modes of image acquisition: You can obtain averaged images when
the camera’s acquisition mode is set to single frame and to continuous and when the camera ac-
quires images continuously (free-run) or when triggers are used.
Each individual image must be triggered separately. Accordingly, for each averaged image the num-
ber of required triggers will be equal to the set number of individual images used for averaging.
When the camera’s acquisition mode is set to single frame, a single averaged image will be ob-
tained. The averaged image will be based on the set number of individual images. The number of
triggers necessary for each averaged image will be equal to the set number of individual images.
For example, if the acquisition mode is set to single frame and the number of individual images used
for averaging is set to three, three triggers are needed to obtain the averaged image.
Note
Make sure that for each averaged image, the number of triggers is equal to the
set number of individual images used for averaging.
Note
Make sure the object being imaged does not move while the sequence of
individual images is acquired. Otherwise, the object will appear blurred in the
averaged image.
Note
Although the camera allows changing the settings for all features while a
sequence of individual images is acquired, we do not recommend to do so. The
new settings would be applied as soon as they are set. Accordingly, the
averaged image would be based on individual images acquired with different
feature settings and poor quality for the averaged image may result.
We recommend to only change the feature settings while individual images
used for averaging are not acquired.
