Multiple regions
All Alvium 1800 U models support single ROI (region of interest). Because multiple
ROI (
MultipleRegions features) are sensor based, it is not supported by all
camera models. With all the corresponding models,
Free mode is available for
MultipleRegionArrangement with 1 to 4 subregions. Other models also support
Tile mode, some models also support Horizontal and Vertical mode with 1 to
4 subregions. See Table 18.
See the specifications tables in Alvium 1800 U model specifications on page 76 for
MultipleRegionArrangement options and Available subregion resolutions on
page 73.
