Image Acquisition
Note:
•
Setting the white balance to 3200 K generally leads to image
reproduction that is closest to the impression of the image in the
microscope’s eyepiece, if the microscope has also been adjusted to this
value. Note that it is recommended to set the gamma curve for the image
display on a value of 0,45 (please find more information in Chapter 2.6
"Practical Notes on Operation in AxioVision" - "Display characteristic
curve").
Clicking on the
button starts an attempt to automatically
adjust the white balance. This requires the presence of sufficient neutral-tint
areas in the image.
Notes:
•
With fluorescence samples or image areas that are completely filled, this
automatic method can lead to color distortion. In this case use the 3200 K
standard setting or the manual color adjustment function.
•
The color setting is only available for the color camera AxioCam
MRc
and
not for the AxioCam
MRm
.

On a microscope, however, the brightness of a halogen lamp is often adjusted
by changing the lamp voltage. This changes the color of the light emitted at
the same time, though.
By moving the
slider it is possible to adjust the
target color value of the white balance to the color distribution of halogen
illumination.
At the middle setting, the color white (R=B=G) is taken as a neutral value. This
neutral value can also be achieved at any time by clicking on the
Reset
button.
Alternatively, you can influence the color channels individually by activating
