Day & Night
 The camera delivers color images during the day. As light diminishes below a certain level, the camera
can automatically switch to night mode (Black & White mode) to maintain good image quality.
 Day & Night function can be selectable according to the environment.
- Auto : Automatically switches to Day (Color) or Night (B&W) according to light using ICR (Infrared
Cut filter Removable).
- Day (Color): Delivers a color image regardless of light.
- Night (B/W): Delivers a B/W image regardless of light.
White Balance
 White Balance has the following modes:
- Auto: This mode computes the white balance value output using color information from the entire
screen. It outputs the proper value using the color temperature radiating from a black subject based
on a range of values from 3000 to 7500K
- Manual: Manual allows control of R and B gain, 256 steps each.
Auto Exposure
 AE Mode
- Full Auto: Auto Iris and Gain, Fixed Shutter Speed (59.94/NTSC:1/60 sec, 50/PAL: 1/50 sec)
DSS (Digital Shutter Speed) mode (Auto or Off) can be selected. When DSS mode is Auto, from
1/2 to 1/60 DSS Limit is available. Back Light Compensation can be selected.
- Manual: 21 steps of Shutter, 18 steps of Iris and 8 steps of Gain can be set manually.
- Shutter Priority: 21 steps (1/2 ~ 1/10,000) of Shutter Speed can be set manually. The Iris and Gain
are set automatically according to the brightness of the subject.
- Iris Priority: 18 steps (F1.8 to Close) of Iris can be set manually. The Shutter Speed and Gain are
set automatically, according to the brightness of the subject.
- Bright: The bright control function adjusts both the Gain and Iris using an internal algorithm
according to a brightness level set by the user. Exposure is controlled by Gain when dark and by
Iris when bright. As both Gain and Iris are fixed, this mode is used when exposing at a fixed camera
sensitivity.
- Spot Light: Avoids a situation where the face of the subject is over-illuminated, and becomes
washed out. In Spot AE, a particular section of the subject can be designated, and then that
portion of the image can be weighted and a value computed so that the Iris and Gain can be
optimized to obtain an image.
