Title
(EN) MEDICAL OBSERVATION SYSTEM
(FR) SYSTÈME D'OBSERVATION MÉDICALE
(JA) 医療用観察システム
Abstract
(EN)
A medical observation system 1 is provided with: an imaging unit 21 which captures an image of a subject to generate a captured image; a distance information acquisition unit which acquires subject distance information including subject distances from a specific position to corresponding positions on the subject that correspond to at least two pixel positions in the captured image; and an operation control unit 264c which, on the basis of the subject distance information, controls at least any of the focal position of the imaging unit 21, the brightness of the captured image, and the depth of field of the imaging unit 21.
(FR)
Système d'observation médicale (1) comprenant une unité d'imagerie (21) qui capture une image d'un sujet pour générer une image capturée; une unité d'acquisition d'informations de distance qui acquiert des informations de distance du sujet comprenant les distances du sujet d'une position spécifique à des positions correspondantes sur le sujet qui correspondent à au moins deux positions de pixel dans l'image capturée; et une unité de commande d'opération (264c) qui, sur la base des informations de distance du sujet, commande au moins l'une quelconque de la position focale de l'unité d'imagerie (21), de la luminosité de l'image capturée et de la profondeur de champ de l'unité d'imagerie (21).
(JA)
医療用観察システム1は、被写体を撮像して撮像画像を生成する撮像部21と、特定の位置から撮像画像における少なくとも2つの画素位置に対応する被写体上の対応位置までの各被写体距離を含む被写体距離情報を取得する距離情報取得部と、被写体距離情報に基づいて、撮像部21の焦点位置と、撮像画像の明るさと、撮像部21の被写界深度との少なくともいずれかを制御する動作制御部264cとを備える。
