Abstract: An image processing method is provided. The method includes detecting a predetermined face area from an input image; converting the input image into Lab coordinates; determining whether coordinate areas having angles corresponding to an angle of the detected face area exist on a Lab color system and searching the input image for the coordinate areas according to a result of the determining; and blurring the detected face area and the found coordinate areas. An image processing apparatus and digital photographing apparatus using the method and apparatus are also provided. Accordingly, reduction of the resolution of a whole image may be prevented by processing only a face area, instead of the whole image, to result in a soft face area image quality. A deterioration in quality of portions which are not supposed to be blurred may be prevented by blurring only a skin color area of the face area.

Abstract: An apparatus and method of removing fixed pattern noise in a digital image processing apparatus are provided. The apparatus includes a controlling unit adjusting a number of image frames of a same image photographed by an imaging device and an exposure time of a shutter, and controlling a movement direction of the imaging device, which photographs the image; and a signal processing unit which median-combines the image frames of the same image photographed by the imaging device during the adjusted exposure time after moving the imaging device. The total photographing time is reduced by skipping a process of photographing a dark image and fixed pattern noise can be effectively removed by median-combining the image frames photographed while physically moving the imaging device between the photographing of consecutive image frames to remove the fixed pattern noise.

Abstract: An apparatus and method of removing fixed pattern noise in a digital camera are provided. The apparatus includes a signal processing unit that calculates location information of the fixed pattern noise from a dark image photographed using an ISO and exposure time that are different from an ISO and exposure time used to photograph a general image, and removes the fixed pattern noise from the general image using the location information. The fixed pattern noise can be effectively removed while reducing the total photographing time in comparison to conventional apparatuses and methods.
