the case if the vertical start angle is set to a value > -30° or if the vertical end
angle is set to a value < 30°. The exposure metering area will then be moved
up or down and set to the center of the remaining vertical scan area. The
following figures illustrate this behavior.

scan area

Zenith Weighted Metering - With zenith weighted metering, the camera will
use the light information coming from above the scanner to determine its
exposure setting. Use this mode if there is very bright light coming from e.g.
windows and if you want to achieve the most correct balance of light and
exposure for objects at the ceiling of building.
HDR mode The High Dynamic Range (HDR) imaging method merges images captured
with different exposure settings to one image with a greater dynamic range of
luminosity.
