Camera does not show up using imaqtool.

Hi,

I am trying to preview my webcam using imaqtool. Below is the code i used. It works fine with webcam support package but when using imaqtool, it shows up like below image.

vid = videoinput('macvideo', 1, 'YCbCr422_1280x720');
preview(vid);

Was the webcam object still in the workspace when you previewed this? That webcam object should be deleted, because the camera can be only be accessed by one object at a given point in time. Use

clear cam % where cam is the webcam object

Hi Madhura Suresh,

My webcam object was not present int the workspace. Still i tried clearing the cam object. It did not work for me.

If using Windows, then does the camera show up in Device Manager? If not, then not even Windows sees the camera, so MATLAB has no chance at it. If it does, then you may need to register a third party adapter from imaqtool's pulldown menu. Ask the camera manufacturer what that file might be, if they have one. If they don't have one, then maybe you can use a generic one instead like DCAM.
