 Once you have a video image, use the brightness and contrast sliders in the middle at the top of the Viewpoint display to adjust the camera image until you get a reasonable picture. Once you have a video image, use the brightness and contrast sliders in the middle at the top of the Viewpoint display to adjust the camera image until you get a reasonable picture.

-====== Mounting the camera inside the video goggles ====== 
- 
-The eyetracker camera was designed to mount inside the rubber shield of the Resonance Technology video goggles. 
-We have modified the camera mounting hardware so that it will fit better inside the head coil and to make it easier to adust the camera position so that it gets a good view of the subject's eye 
-([[biac:experimentalcontrol:eyetrackoriginalsetup|original goggle mount]], 
-[[biac:experimentalcontrol:eyetrackbiacsetup|BIAC goggle mount]]). To mount the camera in the goggles, the regular light gray rubber goggle mask must be replaced by the black rubber mask.\\ 
-**Note:** The rubber goggle mask is held onto the goggles by very delicate rubber hooks that fit over tabs on the goggle casing.  These rubber hooks are fragile and must be handled with care. 
- 
-The camera is inserted into the goggles by sliding the mirror into the slot on the side of the rubber mask with the large opening. The mirror should slide all the way into the mask to avoid having the camer bump into the frame of the head coil. 
- 
-Note: The black mask adds about a centimeter to the thickness of the video goggles (between the subject's eyes and the head coil). Fitting the goggles with camera inside the head coil can be a tight squeeze for some subjects and may not be possible for subjects for large heads. So if you are planning to do eyetracking with the goggles try to avoid using subjects with large heads.  
- 
-Two nylon screws on the camera mount can be used to adjust the camera's view of the eye.
