Auto Exposure

Enabling Auto Exposure causes NetCam to automatically adjust the image exposure based on the overall brightness of the image. The following functions are only implemented when Auto Exposure is enabled.

Brightness - The higher the number, the brighter the picture. The default value is 60.

Sensitivity - This value rarely needs to be adjusted. It sets the sensitivity of the Auto Exposure code. A higher number means a bigger change in lighting is required for the auto exposure to adjust. The default value is 20.

Min & Max - Min is the minimum exposure NetCam will expose images at (default is 0). The default value is the recommended value. Max is the maximum exposure NetCam will expose images at (default is 12500, 1/5 second). If your image looks noisy during low light conditions, you can decrease the max exposure value.

Fluorescent Sync

If NetCam is imaging in an area lit by fluorescent lighting, enabling the appropriate frequency (60Hz for US) will prevent NetCam from producing a change in brightness or color balance that often accompanies imaging under fluorescent lights. For outdoor shots (any other non fluorescent lighting condition), set to off. The default value is off.

Manual Exposure

Enabling Manual Exposure causes NetCam to expose images at the value placed in the Exposure field. Keep in mind that using manual exposure is not advised for outdoor imaging, since the light conditions are constantly changing. You may opt to use manual exposure indoors if your lighting conditions do not change. Here are some sample values and their fractional equivalents:

50= 1/1000 second

500= 1/100 second

833= 1/60 second

1667

=

1/30 second

3333

=

1/15 second

6250

=

1/8 second (may introduce CCD pixel noise)

12500

=

1/4 second (may introduce CCD pixel noise)

Exposure Grid

When Auto Exposure is enabled, NetCam adjusts the exposure of the image based on the average brightness of the pixels located in the selected regions in the Exposure Grid. If you want NetCam to determine the exposure based on only the sky, you would select the squares that apply to the sky
