Image Acquisition with the AxioCam MRc5

Exposure
The camera’s exposure time can be adjusted to the lighting conditions on the
microscope using a slider or by entering an exposure time directly into the
input field. When entering the exposure time manually you can state the value
range directly using the abbreviations "ms" for milliseconds and "s" for
seconds.
Exposure time measurement
The program supports you in calculating an optimum exposure time, at which
the camera will be maximally saturated without being overexposed. To
perform this calculation, click on the
button.
The exposure time calculated is available for subsequent images. It can be
changed at any time by moving the slider or by entering a new exposure time
manually.
This measurement function uses all the image information from the camera
sensor for the exposure measurement as standard (integral measurement).
NOTE:
More detailed information of the live image you can find in chapter 2.6
"Practical Notes on Operation in AxioVision" - " Speed of the live image".
Weighting of exposure time measurement
During an exposure time measurement an attempt is made to expose the
camera in such a way that the sensor is not overexposed in any area of the
image. The value calculated therefore corresponds to 100% of the camera’s
maximum exposure range.
The exposure time measurement can also be adjusted to particular lighting
conditions. If under certain acquisition conditions the exposure time
measurement does not achieve satisfactory exposure of the areas of the
image in which you are interested, it is possible to influence the result of this
measurement by adjusting the weighting.
