Abstract: Provided is a method for eliminating a hologram DC noise and a hologram device using the same. According to the embodiment of the present invention, a method for processing a hologram receives hologram data and performs differential operation. So, the hologram data is processed by differentiating the hologram data. The DC noise generated due to the restoration of the hologram data is effectively removed.
