Video cameras are gaining popularity in embedded systems, either used directly or as sensing devices. Being embedded systems often portable, they can be employed in different environments with various lightning conditions; mutating lightning conditions may pose some problems to conventional video-cameras. Yet, highdynamic range video-cameras can be too expensive for certain applications. In this paper we propose an algorithm that extends the dynamic range of common video-cameras by using limited computational resources, yet exploiting the original frame rate of the camera. Furthermore, we discuss some results obtained by using our algorithm coupled with a commercial webcam.
