Abstract:
(EN) The purpose of the present invention is to provide: an image processing device capable of determining a priority region for performing dynamic range expansion processing to suit the intent of the user in capturing the image; an image capture device; an image processing method; an image capture method; and a program. The image processing device (31) is provided with: an image acquisition unit (301); a region division unit (305) for dividing a captured image into multiple regions; a first white-balance-related information calculation unit (307) for calculating first white-balance-related information on the basis of pixel values in each of the multiple regions; a second white-balance-related information acquisition unit (309) for acquiring second white-balance-related information set by the user vis-à-vis the captured image; and a priority region determination unit (311) for determining a priority region wherein are set the conditions for dynamic range expansion processing performed on the basis of a luminance of the priority region on the captured image.
(FR) Le but de la présente invention est de fournir : un dispositif de traitement d'image capable de déterminer une région de priorité pour effectuer un traitement d'expansion de plage dynamique pour s'adapter à l'intention de l'utilisateur dans la capture de l'image ; un dispositif de capture d'image ; un procédé de traitement d'image ; un procédé de capture d'image ; et un programme. Le dispositif de traitement d'image (31) comporte : une unité d'acquisition d'image (301) ; une unité de division de région (305) pour diviser une image capturée en de multiples régions ; une première unité de calcul d'informations relatives à l'équilibre des blancs (307) pour calculer des premières informations relatives à l'équilibre des blancs sur la base de valeurs de pixels dans chacune des multiples régions ; une seconde unité d'acquisition d'informations relatives à l'équilibre des blancs (309) pour acquérir des secondes informations relatives à l'équilibre des blancs réglées par l'utilisateur vis-à-vis de l'image capturée ; et une unité de détermination de région de priorité (311) pour déterminer une région de priorité dans laquelle sont définies les conditions pour un traitement d'expansion de plage dynamique réalisé sur la base d'une luminance de la région de priorité sur l'image capturée.
(JA) 本発明は、ユーザの撮影意図に合ったダイナミックレンジ拡大処理を行うための優先領域を決定することができる画像処理装置、撮像装置、画像処理方法、撮像方法、およびプログラムを提供することを目的とする。画像処理装置(31)は、画像取得部(301)と、撮像画像を複数の領域に分割する領域分割部(305)と、複数の領域の各々の画素値に基づいて第1のホワイトバランス関係情報を算出する第1のホワイトバランス関係情報算出部(307)と、撮像画像に対してユーザにより設定された第2のホワイトバランス関係情報を取得する第2のホワイトバランス関係情報取得部(309)と、優先領域の輝度に基づいて撮像画像に行われるダイナミックレンジ拡大処理の条件が設定される優先領域を決定する優先領域決定部(311)と、を備える。
