FUNCTIONS

Gain

Used for setting the gain of the video signal amplifier. The gain can be set to 180 steps between the standard gain and maximum +18 dB. (1 step is not 0.1 dB.)

By setting AUTO to ON, the gain will be automatically adjusted to the appropriate exposure. The range of operations is 0 to +18 dB.

Shutter

The CCD exposure time can be set between the maximum 2 seconds and minimum 1/20,000 seconds. By setting AUTO to ON, the exposure time will be automatically adjusted to the appropriate exposure.

Auto Exposure

Used for setting the exposure compensation for when Gain or Shutter or both are operating in the AUTO mode. When both Gain and Shutter are set to Manual, the Auto Exposure setting will be invalid. The range of operations is about –1EV to +0.5EV.

If both Gain and Shutter are operated in the AUTO mode by Auto Exposure, the ranges of operations of both are as follows. (However, these values are approximate values and may differ according to the adjusted and operating states of the camera.)

EV7		EV10			EV17* (SX900)
		AGC			CCD IRIS

* EV16 for X700

Brightness

The brightness of images can be controlled by changing the black level setting. Adjust the brightness if the appropriate gradation cannot be obtained due to the blurring of the black portions of the image.

The range of settings is about 0 to 75 (when gamma is ON (1) in full range 255).
