Image Acquisition
_áååáåÖ=
The process of
Binning
ensures that the information in neighboring pixels, in
both a horizontal and vertical direction, is summarized on the camera's
sensor. This increases image brightness in accordance with the number of
pixels summarized.
However, this process also reduces the sensor's spatial resolution accordingly.
Since the amount of data to be transferred is reduced, the potential image
rate is increased.
EXAMPLE:
In the case of 2 x 2 binning, out of 1400 x1000 pixels 700 x 500 pixels
remain.

The size of the resulting files depends on the choice of resolution and gray
value scaling.

In AxioVision, images in 12 bits per pixel or in 3 x 12 bits per pixel mode can
be saved in ZVI image format. When exporting the images to other image
formats, (TIF, BMP, JPG etc.) this option is not available. With these image
formats the image data are converted from 12 bit to 8 bit data in accordance
with the graduated display characteristic curve.
