to appear in images, e.g. in +70 degrees of celsius the noise level may be very
high, and it further grows if the conditions are dim. If phone processor has been
heavily loaded for a long time before image taking inside of the phone might
have considerably higher temperature than neighbourhood temperature. This is
also normal to camera operation. This is normal behavior, do not change the cam-
era module.
5 Phone display: if the display contrast is set too dark, the image quality degrades
quite much: the images may be very dark, naturally depending on the setting. If
display contrast is set too bright, image contrast appears bad and "faint". This
flaw is easily cured by setting the display contrast to correct value. This is normal
behavior, do not change the camera module.
6 Basic rules of photography, especially shooting against light: due to dynamic
range limitations taking image against bright light might cause either saturated
image or actual target to look too dark. In practice this means that when taking
a picture inside e.g. having a window behind object, will produce poor results.
