APPARATUS AND METHOD FOR CAPTURING IMAGES HAVING OPTIMIZED QUALITY UNDER NIGHT SCENE CONDITIONS

摘要

An apparatus and a method for capturing images having optimized quality under night scene conditions are provided to enable proper exposure of a professional photographic expert level when photographing by a digital camera under night scene conditions or lower illuminance conditions, thereby making an image to be photographed to have the best quality. A first digital image is produced by capturing an image light of a photographing unit(165) from a subject. A night scene detecting unit detects whether the first digital image is a night scene image. When the input image is a night scene image, an exposure adjusting unit(135) adjusts an optimum exposure time by comparing an edge level of the night scene image with a reference image. A controller(130) produces a second digital image based on the adjusted exposure time.
