a = imaqhwinfo;
[camera_name, camera_id, format] = getCameraInfo(a);
vid = videoinput(camera_name, camera_id, format);
set(vid, 'ReturnedColorSpace', 'RGB');
%vid = videoinput('winvideo',1, 'YUV2_1280x720')
img = getsnapshot(vid);
When i capture image from this writtern code, it captures image immediately, and not giving time for camera to set its resolution and image seems black and dark.
How to give some time to camera for waiting to capture good image..?

Either set the exposure:
src = getselectedsource(vidobj);
src.Exposure = newValue; % Make it higher for brighter images.
Or open up the iris diaphragm, if the camera lens has one.

Try
src.FrameRate = 10;
or whatever you used. Maybe you called it input1 instead of src, if so use input1.FrameRate = 10.
