Image Acquisition

Using the slider it is possible to change the interpretation of the brightness of
the image data received. This allows you to display dark images as very bright
images, which means you can acquire images with very high contrast using
short exposure times.
he disadvantage of this technique, however, is that noise is greatly intensified,
and the potential dynamic range of the corresponding image data is reduced.
You should therefore carefully weigh up the benefits of using digital signal
gain before actually employing the technique. For this reason the
recommended value is gain by a factor of 1.
From a technical viewpoint, this technique involves multiplying the data by a
corresponding factor. The maximum numerical pixel value generated is always
limited to the maximum value of the analog/digital converter you are using
(12 bits per pixel per color channel in the case of the AxioCam MR).
Note:
•
You can also achieve a bright image display with short exposure times by
making the display characteristic curve steeper.

An AxioCam MR image is adjusted in such a way that the image orientation
corresponds to the image in the eyepiece when mounted on an upright
microscope with the front of the camera facing you.
This starting position can be adapted via this menu to suit your requirements.
If, for example, the camera’s cable routing needs to be changed on an inverse
microscope, the camera can be mounted at a different angle, without the
correspondence between the image orientation and the eyepiece being lost.
