Background Blur is similar to Background Replacement. Instead of replacing the background entirely, it only blurs it out. This gives the image a more natural look, making the background look out of focus. Background clutter is much less distractive and your chat partner can focus on you instead.
The amount of blur may be controlled by the slider that appears when this feature is enabled.
This feature is available in CatchEye 3D and CatchEye Pro.
