Abstract
Provided is a multi-exposure controlling method and apparatus. An exposure control unit may set an initial exposure time based on a comparison result between a predetermined brightness confidence interval and an average high brightness that is calculated based on at least one current histogram. A comparison unit may compare the brightness confidence interval and an average low brightness that is calculated based on a subsequent histogram obtained by photographing a subject using the set initial exposure time. The exposure control unit may change the initial exposure time based on a comparison result of the comparison unit.
