Abstract: A photographing apparatus, and a photographing method thereof. The photographing method of the photographing apparatus determines if an instruction to photograph is input, and if the instruction to photograph is input, displays a live view by using a first data output from a first pixel group included in an image sensor, and combines a second data output from a second pixel group included in the image sensor with the first data and generates a photographed image, and stores the generated photographed image. Accordingly, the user is continuously provided with the live view even after photographing. Specifically, in continuous photographing, since the user is provided with the live view through which he or she can check the moving subject of photography, the user is enabled to compose images as he or she wishes.

Abstract: An electronic device includes a lens part that receives light from a subject, an image sensor that receives the light of the lens part from a group of pixels arranged two-dimensionally, and an processor that processes an image signal of the image sensor. The image sensor performs a read-out operation at a speed to prevent blurring of an image. The processor temporarily stores image data by the read-out operation in a memory, loads a plurality of images stored in the memory to generate an image, of which the number of bits is expanded compared with the image signal of the image sensor, and performs gamma processing on the image, of which the number of bits is expanded, to generate an image compressed to the same number of bits as the image signal of the image sensor.
