Title (EN) HOLOGRAPHIC IMAGE PROCESSING DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT D'IMAGE HOLOGRAPHIQUE
(KO) 홀로그래픽 영상처리 장치 및 방법
Abstract: front page image
(EN)A holographic image processing device is disclosed. The holographic image processing device for a three-dimensional graphic object, according to the present invention, whereby a three-dimensional graphic object is realized by means of a point cloud method, comprises: a region configuration unit for dividing the visual field of a user into multiple regions; a sampling unit for sampling, per each divided region, points from a three-dimensional graphic object within the visual field of the user, wherein the point density of the sampled points is different per each divided region; and a fringe pattern generation unit for generating a fringe pattern corresponding to each of the sampled points. The present invention has an effect whereby a hologram may be generated at a high speed without degrading the resolution of a holographic reproduction image.
(FR)La présente invention concerne un dispositif de traitement d'image holographique. Le dispositif de traitement d'image holographique pour un objet graphique tridimensionnel conforme à la présente invention, qui permet de réaliser un objet graphique tridimensionnel au moyen d'un procédé de nuage de points, comprend : une unité de configuration de région permettant de diviser le champ visuel d'un utilisateur en de multiples régions ; une unité d'échantillonnage permettant d'échantillonner, pour chaque région divisée, des points d'un objet graphique tridimensionnel dans le champ visuel de l'utilisateur, la densité de points des points échantillonnés étant différente pour chaque région divisée ; et une unité de production de motif de frange permettant de produire un motif de frange correspondant à chacun des points échantillonnés. La présente invention a pour effet de produire un hologramme à grande vitesse sans dégrader la résolution d'une image de reproduction holographique.
(KO)홀로그래픽 영상처리 장치가 개시된다. 본 발명에 따른 3차원 그래픽 객체를 포인트 클라우드 방식으로 구현하는 3차원 그래픽 객체에 대한 홀로그래픽 영상처리 장치는, 사용자의 시야를 복수의 영역으로 분할하는 영역 설정부; 상기 사용자의 시야 범위 내의 상기 3차원 그래픽 객체로부터 상기 분할된 영역 별로 포인트들을 샘플링하는 샘플링부 - 여기서, 상기 샘플링된 포인트들의 점밀도는 상기 분할된 영역 별로 상이함-; 및 상기 샘플링된 포인트들 각각에 대응하는 프린지 패턴을 작성하는 프린지 패턴 작성부를 포함한다. 본 발명은 홀로그래픽 재생 영상의 해상도를 떨어뜨리지 않으면서도 고속으로 홀로그램을 생성할 수 있는 효과가 있다.
