vidDevice = imaq.VideoDevice('winvideo', 1, 'YUY2_640x480', ... 
                    'ROI', [1 1 640 480], ...
                    'ReturnedColorSpace', 'rgb');
set(vidDevice.DeviceProperties, 'Exposure', -7); 
set(vidDevice.DeviceProperties, 'FrameRate', '30.0000');
set(vidDevice.DeviceProperties, 'Sharpness', 100); 
set(vidDevice.DeviceProperties, 'Zoom',2);
