4. A method comprising:
emitting, by an infrared light source of an electronic device, light;
generating, by a camera of the electronic device, first image data;
determining, based on the first image data, a brightness value for the first image data;
determining, based on the first image data, white balance data for the first image data;
determining, based on the white balance data for the first image data and white balance data for the infrared light source, a deviation value; and
changing a setting of the electronic device based on
comparing the brightness value for the first image data to a first threshold, and
comparing the deviation value to a second threshold.
