4-5 Setting the Image Quality (continued)
1Compression Rate
Sets the image compression rate. A lower compression rate means a higher image quality. However, with a reduced compression rate, data volume also increases.
This setting is not available for MPEG4. Value range: 1 to 7 (Set to Ò2Ó at the factory)
2White Balance
Auto | : Automatically adjusts the white |
| balance, the standard for color |
| saturation. Factory set. |
R gain | : To manually adjust the white bal- |
| ance toward more red intensity. |
| Value range: 0 to100 |
B gain | : To manually adjust the white bal- |
| ance toward more blue intensity. |
| Value range: 0 to100 |
3Shutter Speed
1/60 : Normal speed. Factory set.
1/100 : This reduces image flickers due to fluorescent lighting in areas where the commercial power fre- quency is 50 Hz.
4Saturation
Adjusts color saturation. A smaller value makes colors less dense. Set to Ò25Ó at the factory

●AES cannot be turned on when AGC is set to [OFF].
●AES cannot be turned on if the shutter speed is set to [1/100].
●BLC cannot be turned on when AGC is set to [OFF].
●Do not use AES with a DC IRIS lens. It may cause flickering.
6Default
Returns all values, except that for iris level, for image quality to those set at the factory.
7Iris level
Brightness adjustment for a DC IRIS lens.
A smaller value makes images darker, closing the iris.
