“…One software method that requires low level access to the sensor is discussed in (Bandoh et al, 2010). Other methods, such as the ones discussed in (Schulz et al, 2007;Jinno and Okuda, 2012;Guarnieri et al, 2011;Xinqiao and Gamal, 2003;Mertens et al, 2007;Lu et al, 2009;Castro et al, 2011;Wang et al, 2011), are software only, even though they may require the knowledge of different low level parameters of the sensors. All the software techniques are based on the combination of multiple frames to obtain a final image with extended dynamic range.…”

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.
