Neat Image is designed to clean the image of the various kinds of noise and interference - digital photos taken at an overvalued level, ISO, noise produced when digital zoom (digital zoom) in cameras and camcorders, including for partially damaged matrices. And also to correct artefacts produced under strong JPEG-compression, moiré on the scanned printing source code, or "ripped" frame TV-signal or video.
Neat Image can work in two modes - as a standalone program and as a plug-in for Photoshop
