frame from the camera

vid = videoinput('winvideo', 1, 'RGB24_160x120');
data = getsnapshot(vid);

with this code i can get a picture from the camera on Matlab but this camera's options are controlled automatically and i want to get picture from camera manually controlled. i mean i decide the contrast, gain, brightness or exposure values by myself. how can i get picture like that.

There are a lot of cameras which cannot have those parameters controlled. What model of camera are you using?
