ABSTRACT:
Provided are a photographing apparatus and method which can obtain the same effect as in a weighted summation method by capturing a plurality of images of a subject while appropriately controlling exposure time for each of the images and adding up the images and can correct distortions in the images obtained using a typical exposure time division method. The photographing apparatus includes: an exposure compensation value calculation unit which calculates a plurality of exposure compensation values for a plurality of exposure operations respectively corresponding to a plurality of diaphragm values based on a predefined parameter; an exposure unit which respectively performs the exposure operations for exposure times determined based on the exposure compensation values; and an image synthesis unit which synthesizes a plurality of images respectively obtained by the exposure operations.
