Image quality analysis

Possible faults in image quality

When checking for possible errors in camera functionality, knowing what error is suspected significantly
helps the testing by narrowing down the amount of test cases. The following types of image quality problems
may be expected to appear:
• Dust (black spots)
• Lack of sharpness
• Bit errors
In addition, there are many other kinds of possibilities for bad image quality, but those are ruled out from
the scope of this document since the probability of their appearance is small.
