Please explain the terms: dynamic range, and image contrast, and the difference between these two.
Also, how can these two be understood by seeing an image by naked eye for the sake of understanding.
Based on the initial comments on this post, I am trying to add a few lines from the textbook which probably will provide the necessary context behind this question.
Sometimes, the range of values spanned by the gray scale is referred to as the dynamic range, a term used in different ways in different fields. Here, we define the dynamic range of an imaging system to be the ratio of the maximum measurable intensity to the minimum detectable intensity level in the system. As a rule, the upper limit is determined by saturation and the lower limit by noise, although noise can be present also in lighter intensities.
The dynamic range establishes the lowest and highest intensity levels that a system can represent and, consequently, that an image can have. Closely associated with this concept is image contrast, which we define as the difference in intensity between the highest and lowest intensity levels in an image.
For the context, I have been following the textbook Digital Image Processing, 4th Edition, Gonzalez and Woods, pp. 69.
