|
|
| |
AGC MODE | Sets the maximum gain of the AGC (Auto Gain Control), which electronically in- | 10 dB | |||||
| creases the gain when the object is under low light conditions. |
| |||||
| OFF | : Turns the AGC off. |
| ||||
| 10 dB : According to the brightness of the object, gain is increased by up to 10 dB |
| |||||
| 20 dB : According to the brightness of the object, gain is increased by up to 20 dB |
| |||||
| SUPER : Use this setting when brightness is still insufficient under the “20 dB” |
| |||||
|
|
|
| setting. |

|
| MEMO |
|
|
| |
|
|
|
|
| |||
|
| ● When the item “B&W” is set to “AUTO”, [SUPER] is displayed when the item “AGC MODE” |
| ||||
|
|
|
| is set to “SUPER”, and [20 dB] is displayed for other settings. Increase the gain up to the |
| ||
|
|
|
| value displayed. |
| ||
|
| ● Note that increasing gain affects picture quality. |
| ||||
|
| ● When the “SUPER” setting is used, the AGC operation may take a while to adjust to |
| ||||
|
|
|
| sudden drastic changes in the brightness level. |
| ||
|
|
|
|
|
|
| |
SENSE UP | This function is used to increase the sensitivity by extending the exposure time. | OFF | |||||
| When the object is dark, this function sets how high the level of sensitivity will |
| |||||
| automatically increase to. “x32” means that the sensitivity will be increased con- |
| |||||
| tinuously up to 32 times the normal level. |
| |||||
| Increasing this value slows the shutter speed and motion may appear unnatural. |
| |||||
| When the item “SHUTTER” is set to “1/250” or more, the SENSE UP item does not |
| |||||
| work and |
| |||||
| Setting values: OFF, x2, x4, x8, x16, x24, x32 |
| |||||
|
|
|
|
|
|
| |
|
|
| MEMO |
|
|
| |
|
|
|
|
| |||
|
| ● As the setting of the “SENSE UP” function is increased, the picture may become rough |
| ||||
|
|
|
| and whitish, and subject to white blemishes. This is not a malfunction. |
| ||
|
| ● When the setting of the “SENSE UP” function is not OFF, flicker may appear on the |
| ||||
|
|
|
| screen under fluorescent light or mercury lamps. This is due to the principles of the |
| ||
|
|
|
| SENSE UP, and is not a malfunction. |
| ||
|
| ● There may be cases where flicker can not be reduced even under the following condi- |
| ||||
|
|
|
| tions: 1) Shutter speed is set at 1/120 in areas where the commercial electric current |
| ||
|
|
|
| frequency is 50 Hz. 2) The shutter speed is set at 1/50 in areas where the commercial |
| ||
|
|
|
| electric current frequency is 60 Hz. |
| ||
|
|
|
|
|
|
| |
PRIORITY | When an object is dark, this functions sets whether priority during monitoring is | MOTION | |||||
| placed on maintaining the motion of the camera or on picture quality. |
| |||||
| MOTION : Motion of the camera is given priority. When an object is dark, the |
| |||||
|
|
|
|
| AGC function is prioritized. This setting is suitable when objects are |
| |
|
|
|
|
| characterized by quick motion. |
| |
| PICTURE : Picture quality is given priority. When an object is dark, the SENSE UP |
| |||||
|
|
|
|
| function is prioritized. This setting is suitable when picture quality is |
| |
|
|
|
|
| important. |
| |
|
|
|
|
|
|
| |
|
|
| MEMO |
|
|
| |
|
|
|
|
| |||
|
| ● When the “AGC MODE” and “SENSE UP” functions are both set to “OFF”, this function |
| ||||
|
|
|
| does not work and |
| ||
|
| ● When item “B&W” is set to AUTO, item “PRIORITY” is set to the MOTION priority mode |
| ||||
|
|
|
| and |
| ||
|
|
|
|
|
|
| |
ExDR MODE | The ExDR function synthesizes pictures captured at a shutter speed of 1/100 and | OFF | |||||
| those captured at higher shutter speeds to help monitor objects having large differ- |
| |||||
| ences in brightness levels. |
| |||||
| When the “SHUTTER” function is set to “1/250” or a higher, this function does not |
| |||||
| work and |
| |||||
| OFF : Turns the ExDR function off. |
| |||||
| ON : Turns the ExDR function on. |
| |||||
|
|

|
|
|
|
| |||
|
| ● When the ExDR function is on, flicker may appear on the screen under fluorescent light |
| ||||
|
|
|
| or mercury lamps. This is due to the principles of the ExDR, and is not a malfunction. |
| ||
|
| ● There may be cases where flicker cannot be reduced even under the following condi- |
| ||||
|
|
|
| tions: 1) Shutter speed is set at 1/120 in areas where the commercial electric current |
| ||
|
|
|
| frequency is 50 Hz. 2) The shutter speed is set at 1/50 in areas where the commercial |
| ||
|
|
