Metacontrast and motion perception have been related to each other in several ways. At a theoretical level, similarities between the temporal dynamics of visual masking and motion perception have been noted by several investigators. The perceived clarity/blur of moving targets (also known as ‘motion deblurring’) is another phenomenon that reveals a close relationship between metacontrast and motion. The chapter provides a review of basic findings on the motion deblurring, followed by a discussion of mechanisms that can account for this phenomenon. The models discussed include those that rely on motion estimation-compensation mechanisms as well as those that use inhibitory mechanisms. Simulations of the RECOD model pertaining to motion deblurring are also presented.

Keywords:   motion blur, motion smear, motion deblurring, spatiotemporally oriented summation, shifter-circuit model, RECOD model
