Handleiding

EXPOSURE Menu

The EXPOSURE menu is used to set the items related to exposure.

FULL AUTO: The exposure is adjusted automatically using the sensitivity, electronic shutter speed, and iris.

MANUAL: Adjust the sensitivity (GAIN), electronic shutter speed (SPEED) and iris (IRIS) manually.

When you select one from various exposure modes, some of the following setting items that are required for the

selected mode appear.

IRIS PRIOR: Iris Priority mode. The exposure is adjusted automatically using the sensitivity and electronic shutter

speed. Adjust the iris (IRIS) manually.

SHUTTER: Shutter mode. The exposure is adjusted automatically using the sensitivity and iris. Adjust the

electronic shutter speed (SPEED) manually.

BRIGHT: Adjust the brightness level (LEVEL) manually. Select the brightness level from 0 to 31.

When you select one from various exposure modes, some of the following setting items that are required for the

selected mode will appear.

GAIN: Select the gain from the following: 0dB, 3.6dB, 7.1dB, 10.7dB, 14.3dB, 17.8dB, 21.4dB, 25dB, 28.6dB,

32.1dB, 35.7dB, 39.3dB, 42.8dB, 46.4dB and 50dB.

SHUTTER: Select the electronic shutter speed from the following: 1/1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/90, 1/100,

1/125, 1/180, 1/250, 1/350, 1/500, 1/725, 1/1k, 1/1.5k, 1/2k, 1/3k, 1/4k, 1/6k, 1/10k.

IRIS: Select the iris from the following: CLOSE, F1.6,

F2.0, F2.4, F2.8, F3.4, F4, F4.8, F5.6, F6.8, F8, F9.6,

F11, F14, CLOSE

BACKLIGHT MODE:

When the background of the subject is too bright, or when

the subject is too dark due to shooting in the AE mode,

back light compensation will make the subject appear

clearer.

This can be set to ON/OFF.

DEFOG:

Defog: ON, OFF. If the shooting scene has fog, you can

open the defog function to improve the penetration of the

image.

EX-COMP (Exposure Compensation):

When MODE is set to one of FULL AUTO, SHUTTER,

IRIS PRIOR or BRIGHT, set this item to ON to enable

exposure compensation. When you set EX-COMP to ON,

EX-COMP LEVEL can be configured.

EX-COMP LEVEL: Level can be selected from the

following: -10.5dB, -9dB, -7.5dB, -6dB, -4.5dB, -3dB, -

1.5dB, 0dB, +1.5dB, +3dB, +4.5dB, +6dB, +7.5dB, +9dB,

+10.5dB

If you set the level to 0, exposure compensation will be

disabled. Level +10.5 is the brightest and –10.5 is the

darkest compensation value.

When EX-COMP is set to OFF, exposure compensation does not function.

HIGH SENSITIVITY:

In this mode, the maximum gain increases, enabling to obtain a brighter output even in a darker environment.

However, if the gain reaches high level, the image will have a large amount of noise.

SLOW AE (AUTO EXPOSURE)

The slow AE Response function allows you to reduce the exposure response speed. Usually the camera is set

up so that the optimum exposure can be obtained automatically within about 1 second. However, using the slow

AE response function allows you to lengthen the auto exposure response speed from the initial setup speed (01h)

to approx. 10 minutes (30h) (at normal shutter speed).

SLOW SHUTTER:

Slow shutter: ON, OFF. When AUTO SLOW SHUTTER is set to on, it can auto adjust the electronic shutter

speed.

GAIN LIMIT: The gain limit can be set at Full Auto, Manual, IRIS PRIOR, Shutter and Bright mode. Use this

setting when you want to obtain image in which signal-to noise ratio is particularly important.

Select the gain limit from the following: 10.7dB, 14.3dB, 17.8dB, 21.4dB, 25dB, 28.6dB, 32.1dB, 35.7dB, 39.3dB,
