Exposure Failed

mikep

Hi Chad,

I have a problem where sometimes I get into a state where my ASI 178M does not take any exposures anymore, it only reports back 'Exposure Failed' when I check the ASICameraDll2.ExposureStatus.ExpSuccess property every time I try to take an image with my app. Unplugging the camera does not solve the problem. The only thing that helps is to reboot the computer, then everything is fine. This only happens very occasionally but I just wanted to ask if you have any idea why this is happening? Also is there any way to get more information on the error from the AsiCamera object or anywhere else to see what the underlying problem is?

Thanks,

Mike

Hi Mike,

I think it may be disconnect. During our development, we found that sometimes there is a very short disconnection, which leads to a similar phenomenon.

When it happens, please recall GetNumOfConnectedCameras and ASIGetCameraProperty, then call ASIGetNumOfControls to check if the camera had been disconnected. If it had disconnect, ASIGetNumOfControls will return CAMERA_CLOSED.

Thanks

Chad
