When acquiring a photograph of a dark scene, its detail is often deteriorated by sensor noise especially under high ISO sensitivity. On the other hand, using flash photography with artificial light, one can shorten expo- sure time, and a sharp image can be obtained under low ISO sensitivity. However due to a specific color temperature of the additional light, the flash changes color tone and often makes images unnatural. This paper presents a new efficient method for flash/no-flash image integration. Moreover, considering the region which the flush effect from a camera does not reach to, we demonstrate the desirable result at such a photographing condition. In our pro- posal, minimizing different cost function for the region with valid flash effect and invalid flash effect respectively, we achieved noise reduction method that holding contrast at no-flash image. We show the validity of the proposed algorithm by simulating it with some real images. |
