SETTINGS

Electronic shutter settings and electronic iris settings

When all of these switches are down, electronic shutter (1/60 sec or auto iris setting) is enabled. The electronic shutter can be set to one of 7 speeds as shown in Table A.

Furthermore, when all switches are up, electronic iris setting is enabled.

Notes on the electronic shutter:

•Using the high speed electronic shutter indoors with low lighting, will give darker pictures. In such a case, add some lights to make sure the lighting is sufficient. If the lighting is very bright, pay attention to the light angle in order to avoid or minimize the smear phenomenon effect.

•Use a manual or fixed iris lens and set the lens aperture to the shortest F stop. Set the switch (1 – 3) to the up position.

•The electronic iris is suitable for normal indoor use. When the switch (1 – 3) is set to the up position, do not use an auto-iris lens.

•If used under fluorescent light, the image may flicker. In such a case, change to incandescent lighting or set the switch (1 – 3) to the down position and use an auto-iris lens.

•If conditions are outside the electronic iris operation range or more than the maximum illumination, it will cause saturation of the CCD. In that case, use a manual iris lens.

Automatic Gain Control (AGC) setting

The automatic gain control can be turned HI or NORM using the AGC switch 4 in the camera setup section.

HI: Auto gain control fuction on (+6 dB)

NORM: Auto gain control (normal gain)

4

Note: In the AGC switch position HI, noise may be noticed in dark places of dimly lit objects. In the AGC switch position NORM, the noise will be reduced, but the sensitivity will also be reduced to half in this case.

Aperture

This switch 5 (APER) is normally set to the down

(NORM) position. If you would like to emphasize the contours of the object, set the switch 5 (APER) to the

up (SHRP) position.5
