Figure 6: Near objects in image get skewed when shooting from a moving car
Temperature: high temperatures inside the mobile phone will cause more noise 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. This is also normal to camera operation. This is normal
behavior, do not change the camera module.
Figure 7: Noisy image taken in +70 degrees celsius
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 con-
trast 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.
Basic rules of photography, especially shooting against light: electronic image sensors
typically have much lower dynamic range than what films have. In practice this means
that when taking a picture inside e.g. having a window behind object, will produce poor
results. This is normal behavior, do not change the camera module.
