Flicker

In some occasions a bright fluorescent light may cause flicker in the viewfinder and captured image. This

phenomenon may also be a result, if images are taken indoors under the mismatch of 50/60 Hz electricity

network frequency. The electricity frequency used is automatically detected by the camera module. In some

very few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenon

increases. Flickering occurs also under high artificial illumination level. This is normal behaviour; do not

change the camera module.

Especially the sun can cause clearly visible lens glare phenomenon and poor contrast in images. This happens

because of undesired reflections inside the camera optics. Generally this kind of reflections are common in

all optical systems. This is normal behaviour; do not change the camera module.
