•Blue: Adjusts the blue color level of the image.
•Green: Adjusts the green color level of the image.
•Contrast: Adjusts the image contrast level.
•Brightness: Adjusts the image brightness level.
•Saturation: Adjusts the color level of the image.

•Flop: Flips the image vertically. Recommended when the camera is installed upside down.
•Greyscale: Leaves the image in grayscale.

•Sharpen: Applies the edge enhancement effect to the image.
•Deinterlacing: The Deinterlacing filter softens images that are of lower quality due to movement. This effect usually occurs on older analog cameras, at 4CIF resolution. The figure below shows an example of deinterlacing.
