Operation
For a proper operation of your xiMU camera certain requirements must be met. You will read more about these requirements in
the following chapters, as well as a description of how to use a xiMU camera.
4.1.
System Requirements
4.1.1.
Software Requirements
The xiMU cameras are compatible with the following operating systems:
•
Windows 7 SP1
•
Windows 10
•
Linux Ubuntu
•
MacOS 10.8 or newer
All XIMEA cameras are compatible with the most advanced Vision and Image Processing Libraries.

supported libraries and frameworks supported under Windows.
4.1.2.
Hardware Requirements
The XIMEA xiMU USB2.0 cameras are compatible with USB 2.0. System Configuration. The computer system must have a USB
2.0 High-speed interface. For the xiMU USB3.1 Gen1 the computer must have a supported USB3.0 controller. The list of
supported USB3.0 controllers can be found on our
4.2.
Video Formats
4.2.1.
Full Resolution
By default, each camera outputs a full resolution image based on its sensor specification.
4.2.2.
ROIs
–
Region Of Interest
ROI, also called area-of-interest (AOI) or windowing, allows the user to specify a sub-area of the original sensor size for read-out.
xiMU cameras support the definition of one single ROI by specifying the size (width and height) as well as the position (based on
upper left corner) of the of the sub-area.
Since the utilized CMOS sensors rely on the output of full lines, only the decrease of lines, i.e. the vertical resolution, results in an
increase of frame rate.
4.2.3.
Downsampling Modes
Downsampling describes the possibility of reducing the image resolution without affecting the sensors physical size, ie. Without
cropping the image. This feature is useful when optics are used, that are particularly fitted to a certain sensor size and if it is
necessary to maintain the full image circle on the sensor.
Downsampling can be achieved in two ways: binning and skipping/decimation.
