Abstract
Blur-discrimination thresholds for moving, Gaussian-blurred edges were measured. Our results show that motion produces equivalent spatial blur. The velocity dependence of this blur is linear, and its extent can be predicted by a temporal impulse response with a standard deviation of ∼5 ms in normal room light. This blur is most likely to result from cameralike summation and not from the use of larger spatial filters for moving than for stationary objects. As a function of reference blur, blur-discrimination thresholds approach asymptotically a Weber’s-law relation. Motion-deblurring models are discussed in view of our findings, and an alternative model for temporal integration is proposed.
