Error when setting exposure time
显示 更早的评论
I use this to grab the camera I am using,
app.vidobj = imaq.VideoDevice('gentl', 1, 'Mono8');
Then I want to set the exposure time.
relase(app.vidobj);
app.vidobj.DeviceProperties.ExposureTime = 14000;
But I am getting an error:
Unable to set the 'ExposureTime' property of class 'DeviceProperties' because it is read-only.
Any idea what is wrong?
I can change the gamma setting with the same code but with no error.
The camera is a FLIR USB3 camera if that makes any difference.

What is wrong is you're trying to set a read-only property.
If this is a frame grabber, you probably can only set a frame rate.
