28 Using the Document Camera

Increasing Image Contrast

Some images display best when the contrast between the image and its

background is increased. To increase contrast, press the

CONTRAST

button on the document camera. To turn contrast off, press the

button again.

Adjusting the White Balance

Normally, the document camera automatically adjusts the screen’s

white balance. However, it may be necessary to correct for color shifts

in different lighting conditions.

If the displayed image has a color cast, press the

WHITE BALANCE

button on the document camera once to correct the color shift. If you

later want to return to automatic white balance adjustment, press the

button a second time. (See page 30 for manual white balance

adjustments using the document camera’s on-screen display.)

Rotating the Image

You can rotate the image by 90° in a counterclockwise direction each

time you press the

IMAGE ROTATION button on the document

camera. For instructions on rotating the image using the on-screen

display, see page 30.

Reducing Noise in the Image

To reduce noise in the projected image, press the CLEAR MODE

button on the document camera. To exit this mode, press the button

again.
