Ocular motor controller using principle of vestibulo-ocular reflex

Abstract

An ocular motor controller for preventing an image blur by using the principle of vestibulo-ocular reflex in response to translational movement. The ocular motor controller comprises an image pickup section () used as an ocular device, an ocular drive section () for rotating the image pickup section, a distance information acquisition section () for acquiring information concerning the distance from the image pickup section () to a visual target (), a translational movement sensor () for measuring the variation due to the translational movement of a moving object, and a correction section () for utilizing the rotational movement driven by the ocular drive section. The correction section () cancels the variation due to the translational movement measured by the translational movement sensor () and corrects the rotation by the ocular drive section () by using the acquired distance information on the distance to the visual target () and variation information on the variation due to the translational movement so as to fix the image pickup position of the visual target ().
