Understanding Deblurring

This section provides some background on deblurring techniques. The section includes these topics:

• Causes of Blurring
• Deblurring Model

Causes of Blurring

The blurring, or degradation, of an image can be caused by many factors:

• Movement during the image capture process, by the camera or, when long exposure times are used, by the subject
• Out-of-focus optics, use of a wide-angle lens, atmospheric turbulence, or a short exposure time, which reduces the number of photons captured
• Scattered light distortion in confocal microscopy
