More Information
Summary:To provide an incoherent digital hologram signal processing device and an imaging display system capable of converting the depth distance information on a subject image acquired by an imaging part based on the incoherent digital holography into the information according to the actual depth distance of the subject and being sent to a display part.SOLUTION: A signal processing device 30 extracts the shape information (silhouette) and depth distance information on a subject 10 from the three-dimensional image information on the digital hologram photographed by an imaging device 20 based on the incoherent digital holography. The configuration is such that this three-dimensional image information is subjected to the correction processing so as to match the information corresponding to the actual depth distance of the subject 10, and then sent to a display device 40.SELECTED DRAWING: Figure 1 【課題】 インコヒーレントディジタルホログラフィに基づく撮像部で取得した被写体像の奥行距離情報を、実際の被写体の奥行距離に応じた情報に変換し、表示部に送出し得るインコヒーレントディジタルホログラム信号処理装置および撮像表示システムを提供する。【解決手段】 信号処理装置30は、インコヒーレントディジタルホログラフィに基づく撮像装置20で撮影したディジタルホログラムの3次元像情報から、被写体10の形状情報(シルエット)と奥行距離情報を抽出し、この3次元像情報が実際の被写体10の奥行距離に応じた情報に整合するように補正処理を施して、表示装置40に送出するように構成されている。【選択図】図1
