The dynamic range of natural scenes usually exceeds the dynamic range of imaging sensors by several orders of magnitude. To overcome information loss multiple-slope cameras allow acquisition of images at extended dynamic ranges. However the response curve still has to be adapted to the scene. We present a new auto exposure control for multiple-slope cameras. The proposed method derives an optimum response curve in terms of recorded information. It considers dynamic range expansion as well as the resulting coarsening of quantization. We evaluated our method by simulation and implementation for an actual multiple-slope camera.
