The present invention relates to an apparatus for improving image quality, a digital photographing device having the same, and a method for improving image quality. The apparatus for improving image quality comprises: a zone collected reduction filter (ZRF) installed between a lens unit and an image sensor to transmit light which has passed through the lens unit to be irradiated to the image sensor, and having a liquid crystal display (LCD) of which light transmittance for each area which is divided into a plurality of parts is controlled; an image processing unit for processing an image obtained by the image sensor as data; and a ZRF control unit for calculating the brightness of the area divided into a plurality of parts in the image from the data processed by the image processing unit, and controlling the light transmittance of the LCD area in order to reduce brightness difference between the areas in the image. According to the present invention, when excessive brightness difference exists due to light saturation or light shortage for each area in one screen, the light transmittance for each part is controlled by the ZRF which is installed between a camera lens and an image sensor, thereby obtaining an image having excellent definition and color reproductibility. |
