Manual Focus

An image's focus is adjusted manually by rotating the black focus ring at the

front end of the camera. An object can be brought into focus anywhere within a

range from directly in front of the lens to an infinite distance from the camera. If a

wide range of focus is desired, focus the camera on an object more than 5 meters

away and it will allow for a sharp image within a range of 0.6 meters to infinity.

NOTE: When adjusting the focus, be sure not to turn the focus ring counterclockwise so far that it unscrews from

the camera. If exposed, the lenses or internal components of the camera may be scratched or damaged.

The power switch is located on the back of the camera. A green LED on the front

of the camera will remain lit when the camera is switched ON and plugged into

the power jack of the capture card.

Page 1 AMERA UICK EFERENCE The NTSC compliant camera in your Bigpicture package can be adjusted to account for a variety of room conditions and settings. The following instructions provide information on how to adjust the camera, what the adjustments do, and when to use them.
Page 2 Contrast Adjustment The contrast button is used to adjust the contrast of the image produced by the camera. Press the button and hold it until the desired contrast is achieved, then release the button. Clicking the button once will not affect the contrast. If you continue to hold the button in, you will see the contrast change from low to high and back to low contrast continuously until the button is released.
Page 3 White Balance Settings The white balance (WB) switch can be set to either a FIXED or AUTO position. In the AUTO position, the camera automatically adjusts for different light conditions. When the switch is placed in the FIXED position, the camera freezes the white balance to the current setting and does not change until switched back to the AUTO mode, regardless of the lighting conditions.
