device. By increasing the F-stop number (F/1.6, F/2, F/2.4, etc.), less light
is permitted to pass.
MANUAL
In the mode, users can adjust shutter speed (1/10000 ~ 1), iris value (F1.6
~ F28) and gain value (-3dB ~ 28dB).

Exit the AE MODE menu.
R/K Model:
•
AUTO
In this mode, the camera’s Shutter, IRIS and AGC control function work
automatically to compensate the light exposure of image sensor for
consistent video output level. IRIS OFFSET is used to set the level of IRIS
variation (00 ~ 15).
•
SHUTTER
With this option, the priority of SHUTTER is higher than IRIS and AGC;
IRIS and AGC circuit will function automatically in cooperating with
SHUTTER to get consistent exposure. The range of shutter speed for K
model is: 1/30000 ~ 1/2 and for R model: 1/30000 ~ 1/50 (PAL) or 1/60
(NTSC).
•
IRIS
With this option, the priority of IRIS is higher than SHUTTER and AGC;
SHUTTER and AGC circuit will function automatically in cooperating with
IRIS to get consistent exposure. If the IRIS is modified manually, the
action of exposure compensation depends on the AGC circuit. The range
of Iris level is between 00 and 09.
•
AGC
With this option, the priority of AGC is higher than SHUTTER and IRIS;
SHUTTER and IRIS circuit will function automatically in cooperating with
AGC to get consistent exposure. If AGC is adjusted manually, the
exposure compensation depends on the changing of IRIS. The range of
Iris level is between 00 and 05.

A digital camera needs to find reference color temperature, which is a way of
measuring the quality of a light source, for calculating all the other colors. The
