A Depth-Assisted Deblurring Flow Using Dual Cameras with Different Exposure Times

Abstract

Motion blur is often observed when taking pictures of moving objects under long exposure settings. To reduce motion blur, a well-known temporal-domain approach is to use dual cameras with different exposure times, and the deblurred image can be obtained by subtracting one view from another after image warping. In this paper, we propose to modify the abovementioned flow by including depth information, which can greatly improve the qualities of edges in the deblurred images. The proposed method is very effective, especially for scenes with multiple objects moving in different directions at different depths.
