Abstract
(EN) The present electronic device comprises: a memory storing a multi-Light-Field Unit(LFU) structure in which a plurality of light fields are disposed in a lattice structure; and a processor for using the multi-LFU structure to generate a 360 degree image on the basis of a view position when the view position is determined in the lattice structure, wherein the processor selects the LFU to which the view position belongs from the multi-LFU structure, allocates a rendering Field-of-View (FOV) in units of a preset angle on the basis of the view position, generates a plurality of view images on the basis of the allocated FOV and a plurality of light fields forming the selected LFU, and generates a 360 degree image by merging the plurality of generated view images.
(FR) Le présent dispositif électronique comprend : une mémoire stockant une structure à multiples unités de champ lumineux (LFU) dans laquelle sont disposés une pluralité de champs lumineux dans une structure en treillis ; et un processeur pour utiliser la structure multi-LFU pour générer une image à 360 degrés sur la base d'une position de visualisation lorsque la position de visualisation est déterminée dans la structure en treillis, le processeur sélectionne la LFU à laquelle la position de visualisation appartient à la structure multi-LFU, attribue un champ de vision (FOV) de rendu en unités d'un angle prédéfini sur la base de la position de visualisation, génère une pluralité d'images de vue sur la base du FOV attribué et d'une pluralité de champs lumineux formant la LFU sélectionnée, et génère une image à 360 degrés par fusion de la pluralité d'images de vue générées.
(KO) 본 전자 장치는 복수의 라이트 필드가 격자 구조로 배치된 다중 LFU(Light-Field Unit) 구조가 저장된 메모리, 및 격자 구조 내에 뷰 포지션이 결정되면, 다중 LFU 구조를 이용하여 뷰 포지션을 기준으로 한 360 도 이미지를 생성하는 프로세서를 포함하고, 프로세서는 다중 LFU 구조 중 뷰 포지션이 속한 LFU를 선택하고, 뷰 포지션을 기준으로 기설정된 각도 단위로 렌더링 FOV(Field-of-View)를 할당하고, 선택된 LFU를 구성하는 복수의 라이트 필드와 할당된 FOV에 기초하여 복수의 뷰 이미지를 생성하고, 생성된 복수의 뷰 이미지를 병합하여 360도 이미지를 생성한다.
