    摘要: An apparatus and method of capturing images having an optimized quality during night time conditions is provided. The apparatus for capturing images includes an image-capturing unit that captures an light from an object and generates a first digital image, a night-scene-sensing unit sensing whether the first digital image is a night-scene image, an exposure-adjustment unit adjusting an optimized exposure time by comparing an edge level of the night-scene image with that of a pre-generated reference image if it is sensed that the input image is the night-scene image, and a controller controlling the image-capturing unit to generate a second digital image based on the adjusted exposure time.
