you should notice that laptop camera is defferent with usb camera. So you use command :
>> dev_info=imaqhwinfo('winvideo',1)
>> celldisp(dev_info.SupportedFormats)

ans{1} =

YUY2_160x120


ans{2} =

YUY2_176x144


ans{3} =

YUY2_320x240


ans{4} =

YUY2_640x480
then you use :
>> vid=videoinput('winvideo',1,'YUY2_320x240');

I was successful.
Sincerely.
