Abstract
An image compensator includes: a shift path updater for updating a first preliminary shift direction of a fixed image included in an image in a preset first period according a first shift scenario, and updating a second preliminary shift direction of the fixed image in a preset second period according a second shift scenario; a shift direction determiner for correcting the first preliminary shift direction and the second preliminary shift direction respectively to a first target shift direction and a second target shift direction, based on a result obtained by comparing the first preliminary shift direction and the second preliminary shift direction; a first shift controller for performing a first image shift, based on the first target shift direction; and a second shift controller for performing a second image shift, based on the second target shift direction.
