Access modes
The driver for Alvium CSI-2 cameras supports three different access modes to suit
the various requirements of individual applications:
Figure 18 on page 54 shows how cameras are controlled using the different access
modes.
Supported access modes
Alvium 1500 C cameras support Direct Register Access and Video4Linux Access.
Alvium 1800 C cameras will support Vimba Access in addition.
CSI-2 Access Mode Description
Direct Register Access Controls the camera by reading from and writing to registers, using an
embedded board or an FPGA. See the
Direct Register Access Controls
Reference document at https://www.alliedvision.com/en/support/
technical-documentation/alvium-documentation.html .
Video4Linux Access Controls the camera by V4L2 controls, using the Allied Vision driver for CSI-2
cameras directly.
Existing PC-based machine vision applications can be scaled down to V4L2 on
lean embedded systems, reducing power consumption and costs.
Vimba Access Controls the camera by GenICam features, using Vimba .
Existing V4L2 applications can be extended by changing from the basic set of
V4L2 controls to the GenICam feature set.
