METHOD AND A DEVICE FOR RECONSTRUCTING AN ALL FOCUSED HOLOGRAM WITH IMPROVED AESTHETIC SENSES, IMAGE RECOGNITION PROPERTIES, AND PRACTICALITY

摘要

PURPOSE: A method and a device for reconstructing an all focused hologram are provided to improve the image quality of a hologram by focusing on all parts of the hologram when a digital hologram is reconstructed.;CONSTITUTION: Digital hologram reconstruction units (110-1 to 110-N) reconstruct digital hologram data by different focal distances. A plurality of focusing parameter computation units (120-1 to 120-N) produces focusing parameters with respect to each digital hologram. A comparison unit (130) compares the focusing parameters by pixel units. The selecting unit (140) combines the digital holograms into a single digital hologram on the basis of the comparison result.;COPYRIGHT KIPO 2013;[Reference numerals] (110-1) Digital hologram reconstruction unit-1; (110-2) Digital hologram reconstruction unit-2; (110-N) Digital hologram reconstruction unit-N; (120-1) Focusing parameter computation unit-1; (120-2) Focusing parameter computation unit-2; (120-N) Focusing parameter computation unit-N; (130) Comparison unit; (140) Selecting unit; (AA) Digital hologram data; (BB) All focused digital hologram
