Acquisition Modes - Zeiss AxioCam MRc5 Installation Reference Manual

Image Acquisition with the AxioCam MRc5
reduce the amount of data. The camera will always acquire a color image,
which is then converted to a black and white image.
Depending on the selected mode certain binning modes are available.

Acquisition modes

The AxioCam MRc5 essentially offers two acquisition modes: "Quality" mode
and "Fast" mode. These modes are determined by the technical functioning
of the sensor.
The sensor is a so-called "Interlace" sensor, which reads out an image with
full sensor resolution in two interlaced acquisition steps. This technique is used
in "Quality" mode and offers the highest possible resolution of detail. This
mode should therefore also be the preferred mode at low microscope
magnifications, to ensure the optimum recording of the objective's resolution.
The disadvantage of this technique, however, is that it is less well suited to
changing acquisition conditions or moving objects. This is because the
moments of acquisition of the two component images are very slightly
different. If the object being acquired moves during acquisition, this can lead
to disruptive effects.
For this reason "Fast" mode is available for the acquisition of changing
objects. This mode uses only one sensor field. This can be generated and read
out in a single exposure, allowing moving objects to be acquired effectively. In
the specialist literature, this mode is also described as "Progressive" mode.
The compromise here is that the spatial resolution in the vertical direction is
halved. However, this has no effect at high microscope magnifications.
The following table provides an overview of the selectable camera modes and
resolutions.
