Abstract
A digital holography device of an embodiment of the present invention includes: an image sensing device which records, in an image sensor and on the basis of an object, a plurality of holograms that correspond to respective different photographic exposure values; and a computer which (i) generates a high dynamic range hologram, which includes pieces of information ranging from low luminance information to high luminance information, by synthesizing the plurality of holograms recorded and (ii) generates a reconstructed image of the object by performing arithmetic processing of phase-shift interferometry, diffraction calculation, and/or the like on the basis of the high dynamic range hologram.
