Analysing image quality

Possible faults in image quality

When checking for possible errors in the flash functionality, knowing what error is suspected, significantly

helps the testing by narrowing down the number of possible test cases. The following types of image quality

problems may be expected to appear:

• LED module is not flashing at all

• Image colours are not good

• Flash power is weak

Testing flash module functionality

Context

With the help of this test you can check the flash module's overall functionality.

Always set the flash to FORCED FLASH mode when performing the test. The FORCED FLASH mode enforces the

LED module to flash, even if there is some ambient light present.
