Please try

devinfo = imaqhwinfo('winvideo', 2);
devinfo.SupportedFormats

Notice for example that you are asking for a format with 720 x 480, but the camera is saying it is 480 x 720.

Thank u for your suggestion,i tried it out.. *devinfo = imaqhwinfo('winvideo', 2); devinfo.SupportedFormats

ans =

    'UYVY_720x480'    'UYVY_720x576'*
i changed the format to 720 X 480....
still the same problem persists....
Is there any other area where i am going wrong
