The present invention relates to a device and method for digital hologram recording and reconstructing that solves the problem of overlapping real and virtual images when reconstructing a hologram with a digital hologram device such as a digital hologram microscope. The device comprises a hologram reconstructing module for dividing the hologram area recorded on the CCD, recording in the interim each divided area whereby for each of the areas the pixel values of the rest of the areas except for that divided area is set to zero, outputting a reconstructed image with the virtual image removed by integrating each of the reconstructed hologram images recorded in the interim, and a control unit for controlling the hologram recording on the CCD, including dividing, mid-recording, and integration operations of the hologram reconstructing module, thus leading to perfect holographic information of the object. |
