High dynamic range video by spatially non-regular optical filtering

We present a new method for capturing high dynamic range video (HDRV). Our method is based on spatially varying exposures, where individual pixels are covered with filters for different optical attenuation. For preventing the loss in resolution we use a new non-regular arrangement of the attenuation pattern. Subsequent image reconstruction based on the sparsity assumption allows the reconstruction of natural images with high detail.
