Abstract
A digital camera may include a flash unit configured to emit light to illuminate a subject using a preliminary light emission operation followed by a main light emission operation, an image sensor having a pixel array arranged along a plurality of lines, and a digital signal processor. The image sensor may be configured to convert an image of the subject into an electrical signal by reading an image frame corresponding to one screen using the pixel array during the preliminary light emission operation and reading another image frame corresponding to one screen during the main light emission operation. The digital signal processor may be configured to control the light emitting operation of the flash unit to maintain the preliminary light emission from a start to an end of the reading of one image frame.
