Title (EN) 3D IMAGE DISPLAY DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ D'AFFICHAGE D'IMAGE EN 3D
(KO) 3D 영상 표시 장치 및 방법
Abstract:
(EN) Disclosed are a device and a method for displaying a 3D image. A 3D image display device comprises: a stereo image analysis unit which receives a stereo image having a left image and a right image, and detects image information that contains edge information, color information, and/or scene change information; a first depth adjusting unit which determines a reference point by analyzing the distribution of depth of the stereo image based on the detected image information, and adjusts a three-dimensional effect of the stereo image by shifting the stereo image based on the determined reference point; a second depth adjusting unit which extracts depth map information in a pixel unit after reducing the size of the stereo image, and generates an image of a new viewpoint by warping the extracted depth map information such that the three-dimensional effect of the stereo image is adjusted; and a formatter which converts, according to a display device, the format of the stereo image having a three-dimensional effect adjusted by the first depth adjusting unit and/or the second depth adjusting unit.
(FR) La présente invention se rapporte à un dispositif et à un procédé permettant d'afficher une image en 3D. Un dispositif d'affichage d'image en 3D comprend : une unité d'analyse d'image stéréo qui reçoit une image stéréo qui comprend une image gauche et une image droite, et détecte des informations d'image qui comportent des informations de bord, des informations de couleur et/ou des informations de changement de scène ; une première unité de réglage de la profondeur qui détermine un point de référence par analyse de la distribution de la profondeur de l'image stéréo sur la base des informations d'image détectées, et règle un effet tridimensionnel de l'image stéréo par modification de l'image stéréo sur la base du point de référence déterminé ; une seconde unité de réglage de la profondeur qui extrait des informations de carte de profondeur dans une unité de pixel après réduction de la taille de l'image stéréo, et génère une image d'un nouveau point de vue par déformation des informations de carte de profondeur extraites de telle sorte que l'effet tridimensionnel de l'image stéréo soit ajusté ; et un formateur qui convertit, selon un dispositif d'affichage, le format de l'image stéréo qui présente un effet tridimensionnel réglé par la première unité de réglage de la profondeur et/ou par la seconde unité de réglage de la profondeur.
(KO) 3D 영상을 표시하는 장치 및 방법이 개시된다. 3D 영상 표시 장치는 좌 영상과 우 영상으로 구성된 스테레오 영상을 입력받아 에지 정보, 칼라 정보, 장면 변화 정보 중 적어도 하나를 포함하는 영상 정보를 검출하는 스테레오 영상 분석부, 상기 검출된 영상 정보를 기반으로 상기 스테레오 영상의 깊이 분포를 분석하여 기준점을 결정하고, 상기 결정된 기준점을 기준으로 상기 스테레오 영상을 쉬프트시켜 상기 스테레오 영상의 입체감을 조절하는 제1 깊이 조절부, 상기 스테레오 영상의 크기를 줄인 후 픽셀 단위로 깊이 맵 정보를 추출하고, 추출된 깊이 맵 정보를 와핑하여 새로운 시점의 영상을 생성함에 의해 상기 스테레오 영상의 입체감을 조절하는 제2 깊이 조절부, 및 상기 제1 깊이 조절부와 제2 깊이 조절부 중 적어도 하나에서 입체감이 조절된 스테레오 영상을 디스플레이 장치에 맞게 포맷 변환하는 포맷터를 포함할 수 있다.
