How difficult is image processing?

Not an easy task. Of course, you can attempt to simulate the way we see with two eyes by taking two pictures simultaneously and extracting 3D information from these. This is called stereoscopic vision. However, stitching images together is also not a trivial task and is, hence, likewise an open area of research.

What are the problems in digital images?

Among the most common problems in digital photography are pictures that are incorrectly exposed and are too light or too dark. This problem is usually caused by the camera exposure system reading the background and compensating for it.
