Abstract: Compared to traditional video acquisition, high-dynamic range video increases the visual experience, enhances the possibilities in post-production and simplifies stage lighting. However, existing techniques for high-dynamic range video capture are too expensive for low and medium budget cameras. Furthermore, they are not suitable to handle the most challenging lighting conditions. Against this background, the paper presents a novel technique for capturing high-dynamic range video. It is based on a non-regular mask of attenuation filters placed in front of a standard sensor. Compared to a traditional sensor with the same resolution, the captured image shows nearly the same amount of detail, but it has a much higher dynamic range. The achievable dynamic range increment depends on the underlying sensor capabilities. For highest quality requirements, a 12 f-stop sensor can be extended by 2 to 5 f-stops, a 14 f-stop sensor can be extended by 4 to 7 f-stops. The renouncement of bracketing avoids motion artifacts and reduces the data volume read from the sensor.
