4.2Image Processing Options

The images produced by NetCam are processed and compressed inside the camera. Many options that affect the quality of the image are available on the Image Properties Page -- the important ones are listed here (for a complete list, see Chapter 2.1).

Brightness - This controls how the bright the auto exposure will adjust the image. When auto exposure is enabled (which it should be, especially when doing outdoor imaging), this is the main control you will need to adjust to increase or decrease the overall brightness of the live images. If your images are coming out dark during daylight (or indoor lighting), increase this value.

Saturation - This value represents the amount of color in the image. The higher the number, the more the saturated the colors become. The default value works well in most cases. If you do want more color saturation, increasing the number from its default of 1200 to 1300 should do the trick. Anything higher may start to produce undesired color effects.

Gamma - This adjusts the amount of detail visible in shadowy areas, at the expense of increased haziness. Try increasing the default value of 1700 to 1800 to see more details in dark areas. Or if you want more contrast, reduce it to between 1000 and 1500.

Sharpen - For the best quality images, this should always be left on.

JPEG Quality - The default value of 70 works well in most cases. The compression artifacts are minimal and the file size small. While increasing the quality will result in a slightly clearer image (less JPEG compression artifacts), the significantly increased file size hardly makes it worthwhile, especially when the quality is set to 90 or higher. Conversely, if you’d like images to download/upload faster for viewers with dial-up Internet connections, you can reduce the JPEG quality which decreases the file size. A value of 50 still results in good looking images at a very small file size.
