Introduction to camera troubleshooting
Bad conditions often cause bad pictures. Therefore, the camera operation has to be checked in constant
conditions or by using a second, known-to-be-good Nokia device as reference. Image quality is hard to
measure quantitatively, and the difference between a good and a bad picture can be small. Some training
or experience may be needed to detect what is actually wrong.
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
are common:
•
Dust (black spots)
•
Lack of sharpness
•
Bit errors
