Abstract
Spatially varying exposures via rolling shutter is an efficient way to capture differently exposed images for high dynamic range (HDR) scenes. Neither camera movement nor moving objects is an issue for such a captured method. However, a possible issue is that the resolution of captured images is reduced. In this paper, we introduce a novel cross image cubic interpolator for the spatially varying exposures via the rolling shutter. Both intra correlation among pixels with the same exposure and inter correlation among pixels with the different exposures are utilized by the proposed interpolator. Experimental results show that quality of upsampled images is significantly improved.
