Compression Rate | The compression rate is inversely proportional to the image quality. |
| When the compression rate is small, the image quality can be |
| improved but the data quantity increases. |
Saturation | This adjusts the development of colors. |
| Increasing this value increases color saturation. |
White Balance | When [AWB] is checked, the auto white balance circuit controls the |
| white balance automatically. |
| When [AWB] is not checked, the R Gain and B Gain settings are activated. |
|
|
Brightness | • When [AGC] is checked, the gain of the internal amplifier is |
| adjusted automatically according to the surrounding brightness. |
| • When [BLC] is checked, the back light compensation function is |
| activated. One of the five |
| menu can be selected. The brightness will be adjusted |
| automatically based on the selected |
| CAUTION : The BLC function does not work effectively unless [AGC] is checked. |
Shutter Speed | Select [1/60] for normal image capturing. To reduce flickering under |
| fluorescent lighting, etc., select [1/100] if the local power voltage is |
| 50 Hz or [1/60] if it is 60 Hz. |

Resolution | Select the image size from “640 x 480”, “320 x 240” and “160 x 120”. |
| When [Cornpensate aspect ration when 160 x 120 selected.] is checked, |
| the image size of the “160 x 120” display becomes actually 160 x 112. |
JPEG Frame Rate | Select the maximum number of frames transmitted from the VN- |
| C30U per second. |
|
|
CAUTION
•The actual number of frames transmitted or displayed per second is dependent on the performance of the PC, type of web browser and LAN environment. In case communication faults involving the processing of other users are expected (particularly when the network environment is usually subjected to a relatively heavy load), it is recommended to set the frame rate to a lower value.
•When a large image size (640 x 480) is used, the upper limit of the frame rate is limited at 3 fps regardless of the setting made in [JPEG Frame Rate].
•Be sure to adjust [JPEG Frame Rate] in consideration of the number of simultaneous accesses to the unit.If its processing capability is exceeded, it will be impossible to perform correct operations including the web page display, movement and button operations.
