1. A method for controlling an exposure level for a digitally zoomed image included in a wide angle image, the method comprising:
acquiring first statistics concerning a luminance level in the digitally zoomed image and second statistics concerning a luminance level in the wide angle image;
estimating whether an exposure level for the digitally zoomed image should be compensated, by using the first statistics and the second statistics; and
determining a target exposure level for the digitally zoomed image based on the estimation result.
