B-3-5 AE MODE

The exposure is the amount of light received by the image sensor and is

determined by how wide you open the lens diaphragm (iris adjustment), by

how long you keep the sensor exposed (shutter speed), and other exposure

parameters. With this item, users can define how the Auto Exposure (AE)

function works.

¾ 18x MODEL

♦ AUTO

In this mode, the camera’s IRIS and AGC (Auto Gain Control) control circuits

work together automatically to adjust the light exposure of image sensor in

order to get consistent video output level. At this condition the shutter speed is

fixed at 1/60 (NTSC) or 1/50(PAL). Users can offset the internal brightness

reference level through auto Exposure Comp. to control the brightness of

camera. The value of Exposure Comp. is selectable from <0> to <16> and the

gain varies from -10.5 dB to 10.5 dB. Each step is 1.5 dB; the Exposure Comp.

vaue <7> is equal to gain value 0 dB. The camera will not compensate

brightness when the Exposure Comp. is set to <OFF>. The default setting is

<OFF>.
