A photographing apparatus requiring a short initialization time, and a method thereof are provided. The photographing apparatus includes a camera part for converting an optical image converged through a lens into an electric signal, and processing the electric signal into an image signal, a first memory for temporarily storing the image signal generated at the camera part, a second memory for storing the image signal stored in the first memory, and a signal processing part for temporarily storing the image signal to the first memory during initialization of the second memory, and upon completion of the initialization of the second memory, storing the image signal stored in the first memory to the second memory. As a result, initialization time of the photographing apparatus is shortened.
