Abstract
A multi-step exposure method using an electronic shutter and a photography apparatus using the same are provided. The photography apparatus includes an image sensor, and a control unit which divides an area of the image into a first area and a second area using brightness information of the acquired image, and controls so that a first row group and a second row group of the second area have different exposure times. As a result, an image with a wider dynamic range is provided.
