Edge enhancement is used to make the edges of lines appear sharper and more distinct. It gives the
appearance of increased resolution, but in reality the resolution is determined purely by the number of
pixels, and is fixed.

Back Light Compensation (BLC Control)
Under normal lighting conditions, with the Electronic Iris control activated, the camera will automatically
adjust the image brightness so that all parts of the image are visible.
However when the background illumination is very bright, as when someone is standing in front of a
window for example, the shutter speed will automatically be reduced causing the foreground image to
appear darkened. With the image appearing in this way, faces may look almost in silhouette making it
difficult to see any detail.
In this situation, Back Light Compensation (BLC) can be used to increase the brightness of certain parts of
the image.
Back Light Compensation effectively limits the area of the screen in which the AGC operates, thus
ensuring that details within the area will not be lost. As a consequence, regions of the image outside of
the BLC area may become very bright and washed out.
To enable BLC simply click on the Enable Backlight Compensation Check box.
The size of the BLC window can vary in both size and shape. To change the BLC size, click on the Region
Width and/or the Region Height radial buttons and choose 1/8, ¼, ½, or Full.
To change the X or Y position, click on the arrows provided above and/or to the left of the 8 x 8 grid.
