Shutter Sequence Design: Noise Experimental Results

By Scott Mccloskey

Abstract

We extend the flutter shutter method of Raskar et al. [1] to fast-moving objects by first demonstrating that no coded exposure sequence yields an invertible point spread function for all velocities. Thus, the shutter sequence must depend on object velocity, and we propose a method to compute such velocity-dependent sequences. We demonstrate improved image quality from velocity dependent sequences on fast moving objects. Velocity-Dependence The objective of exposure coding is to choose a shutter timing sequence that produces an invertible Point Spread Function (PSF), i.e. one whose MTF does not go to zero. But, the effective PSF depends on both the shutter sequence and the object’s velocity. For a given sequence, how does reconstructed imag
