1. A method of controlling setting for a camera, the method comprising:
learning a first function representing a relationship between a plurality of image characteristic values and camera parameter values including a gain value and a shutter speed value at a first lighting condition, wherein the plurality of image characteristic values include at least one of a noise value, a blur value and a contrast value;
calibrating a second function by adapting the first function to a second lighting condition based on a plurality of image characteristic values at the second lighting condition and the first function;
selecting camera parameter values for the second lighting condition based on the calibrated second function; and
setting the camera according to the selected camera parameter values.
