Engineers and scientists spend a good deal of time determining the optimal resolution for an image since the wrong resolution can render an automated diagnostic system useless. Higher resolution provides flexibility in working with an image, such as the ability to focus in on interesting areas of an image. But higher resolution has drawbacks. Doubling resolution quadruples the processing burden of the computer. Dynamic Range Digital imaging systems provide more information than humans and in some cases new information.
Dynamic range is a prime example.
The dynamic range of an imaging system is the number of shades of gray it can identify between black and white. Human vision has a dynamic range of roughly 70 gray shades. Even the most rudimentary CCD camera has a dynamic range of 256 gray shades, and some may extend this into the thousands. Multi-Spectral Imaging Digital imaging systems also open up the color spectrum. While humans see only a small portion of the color spectrum, digital imaging devices can easily extend their detection range into the infrared and the ultraviolet.
