Understanding Deblurring
This section provides some background on deblurring techniques. The section includes these topics:
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 reduced the number of photons captured
- Scattered light distortion in confocal microscopy
