Abstract
Provided are a hologram object position estimating apparatus and method for estimating a position of an object recorded in a hologram at a high speed using only light wave information recorded in the hologram. The apparatus for estimating a position of a hologram object includes a local spatial frequency calculating unit configured to calculate a local spatial frequency on a plane based on input hologram data, and a light ray focal point calculating unit configured to calculate a focal point on which light rays starting from the hologram plane converge on a hologram plane using the local spatial frequency calculated by the local spatial frequency calculating unit to estimate a position of an object.
