Figure 63 Noisy image taken in +70 degrees CelsiusPhone displayIf the display contrast is set too dark, the image quality degrades: the images may be very dark dependingon the setting. If the display contrast is set too bright, image contrast appears bad and "faint". This problemis solved by setting the display contrast correctly. This is normal behaviour; do not change the camera module.Basic rules of photography (especially shooting against light)Because of dynamic range limitations, taking images against bright light might cause either saturated imageor the actual target appear too dark. In practice, this means that when taking an image indoors and having,for example, a window behind the object, the result is usually poor. This is normal behaviour; do not changethe camera module.Figure 64 Image taken against lightFlickerIn some occasions a bright fluorescent light may cause flicker in the viewfinder and captured image. Thisphenomenon may also be a result, if images are taken indoors under the mismatch of 50/60 Hz electricitynetwork frequency. The electricity frequency used is automatically detected by the camera module. In somevery few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenonincreases. Flickering occurs also under high artificial illumination level. Flickering only occurs when the rollingshutter is used. This is normal behaviour; do not change the camera module.RM-132; RM-133Nokia Customer Care Camera Module TroubleshootingPage 8 –8 COMPANY CONFIDENTIAL Issue 1Copyright © 2006 Nokia.
