In this review some recent psychophysical studies concerning mechanisms for spatial localization of visual objects, especially those that relate to vernier hyper-acuity in both static and dynamic situations were surveyed and discussed. The viewpoint adopted was to regard the function of the early visual processing to be the local analysis of spatial frequency with localized filters. Three approaches were introduced and commented upon to explain vernier acuity, and the plausibilities of the respective approach were evaluated. Thus, vernier acuity may be understood by supposing a process of localizing visual edges, orientation selectivity and/or phase sensitivity of visual channels. Moreover it was pointed out that the spatio-temporal averaging of visual positions was essential in the case of dynamic vernier acuity, especially for detection of the temporal offset.
