Summary:PROBLEM TO BE SOLVED: To provide an image recording device for simultaneous multiple recording of a plurality of element holograms in the same region of a hologram recording medium upon forming a holographic stereogram.SOLUTION: The image recording device includes: splitting means that splits a laser beam emitted from a laser beam source; a display device that displays an image; display controlling means that controls display of the display device in such a manner that a display region is divided so as to display a plurality of images for forming a holographic stereogram and that one of the split laser beams is modulated by the plurality of images displayed on the display device to give a plurality of object beams; an optical system that superposes the plurality of object beams one another on a hologram recording medium to form images; and irradiating means that irradiates the hologram recording medium with the plurality of object beams together with the other split laser beam as a reference beam.SELECTED DRAWING: Figure 3 【課題】ホログラフィックステレオグラムを作成する際に、ホログラム記録媒体の同じ領域に複数の要素ホログラムを一度に多重記録する画像記録装置を提供する。【解決手段】レーザ光源から出射されたレーザ光を分岐する分岐手段と、画像を表示する表示装置と、表示領域を分割してホログラフィックステレオグラム作成用の複数の画像を表示し、分岐された一方のレーザ光が表示装置に表示された複数の画像の各々で変調されて複数の物体光となるように表示装置の表示を制御する表示制御手段と、複数の物体光をホログラム記録媒体上に重ね合わせて結像する光学系と、分岐された他方のレーザ光を参照光として複数の物体光と共にホログラム記録媒体に照射する照射手段と、を備える画像記録装置とする。【選択図】図3
