My camera supports setting the exposure time. I would like to know how to set this.

This change has been incorporated into the documentation in Release 14 Service Pack 3 (R14SP3). For previous releases, read below for any additional information:

The following solution shows how to view and set all the device-specific properties supported by a camera. If the exposure time can be set, it will be listed in the device-specific properties:

MATLAB: Relation of exposure time and ExposureTimeAbs for GigE videoinput adaptor

For the videoinput GigE adaptor, ExposureTimeAbs is a standard GenICam property.

The units are set by the camera manufacturer per the GenICam SFNC standard. You can use the PROPHELP function to get info on a property (this inf is also provided by the camera manufacturer in the camera XML file). For example, here is the output with a camera I have on my desk. The units for ExposureTimeAbs are in microseconds.

>> v=videoinput('gige',1);
>> s=v.Source;
>> prophelp(s,'ExposureTimeAbs')
ans =
'EXPOSURETIMEABS double [31 1000000] (Read-only: notCurrently)
Sets the exposure time in microseconds (us) when ExposureMode is set to Timed.
See also PROPINFO, and ExposureMode.'

MATLAB: Are ‘The Imaging Source’ USB cameras supported with Image Acquisition Toolbox

For USB cameras, the individual model compatibility is better addressed by the specific vendor in terms of compatibility with a particular driver they provide.

For these two particular cameras, the vendor appears to provide drivers for Windows only:

Please confirm with the manufacturer if the drivers are compatible with

compliant imaging applications on Windows. If this is the case, the camera may work with Image Acquisition Toolbox:
