Figure 82 Noisy image taken in +70 degrees Celsius

Phone display

If the display contrast is set too dark, the image quality degrades: the images may be very dark depending on

the setting. If the display contrast is set too bright, image contrast appears bad and "faint". This problem is

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 image

or 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 change the

camera module.
