22 Using the Document Camera
Adjusting the Brightness
The document camera is initially set to
auto iris. When using the camera, you can
manually adjust the iris to control the
amount of light that reaches the lens.
If the screen looks dark, press the
Open
button to open the iris so that more light
reaches the lens. If the screen looks too
light, press the
Close
button. To return to
the default setting of auto iris, press the
Normal
button.
Using the Camera Head as a
Conventional Video Camera
By adjusting the camera head to a horizontal position, you can use the
document camera like a conventional video camera. To view walls or
distant objects, flip down the close-up lens. The document camera can
resolve images from 3.6 feet (1.1 m) to
∞
(infinity).
