Camera Module Troubleshooting
Testing Flash power
For testing flash power, take an image with the flash in total darkness (ambient light level < 1 lux) from the
target about 80cm – 1m away from you.
If the flash is working normally with adequate power level the image is correctly exposed from 80cm – 1m
distances. Remember that the brightness level in the corners is always less than in the center of the image,
due to camera and flash optics.
