Abstract:
(EN) A focus detection device comprises: a plurality of micro lenses that are placed in a two-dimensional shape where a light beam passing through an imaging optical system is incident; a plurality of light receiving elements that are respectively placed correspondingly to the plurality of micro lenses; a focus detection unit that detects the phase difference between a plurality of light beams which pass through another area of the imaging optical system based on the output of the plurality of light receiving elements and detects the defocus amount of the imaging optical system; and a recognition unit that recognizes the feature of a subject image formed on the plurality of light receiving elements by the plurality of micro lenses based on the output of the plurality of light receiving elements. The focus detection unit detects the defocus amount through a method suitable for the feature of the subject image recognized by the recognition unit.
(FR) L'invention concerne un dispositif de détection de foyer comprenant : une pluralité de microlentilles qui sont placées en une forme bidimensionnelle où un faisceau lumineux passant à travers un système optique d'imagerie est incident ; une pluralité d'éléments récepteurs de lumière qui sont respectivement placés en correspondance avec la pluralité de microlentilles ; une unité de détection de foyer qui détecte la différence de phase entre une pluralité de faisceaux lumineux qui passent à travers une autre zone du système optique d'imagerie en se basant sur la sortie de la pluralité d'éléments récepteurs de lumière et détecte la quantité de défocalisation du système optique d'imagerie, et une unité de reconnaissance qui reconnaît la particularité d'une image objet formée sur la pluralité d'éléments récepteurs de lumière par la pluralité de microlentilles en se basant sur la sortie de la pluralité d'éléments récepteurs de lumière. L'unité de détection de foyer détecte la quantité de défocalisation via une méthode adaptée pour la particularité de l'image objet reconnue par l'unité de reconnaissance.
(JA)  焦点検出装置は、結像光学系を透過した光束が入射する、二次元状に配置された複数のマイクロレンズと、複数のマイクロレンズの各々に対応して配置された複数の受光素子と、複数の受光素子の出力に基づいて、結像光学系の異なる領域を通過した複数の光束の位相差を検出し、結像光学系の焦点ずれ量の検出を行う焦点検出部と、複数の受光素子の出力に基づいて、複数のマイクロレンズにより複数の受光素子上に形成される被写体像の特徴を認識する認識部とを備え、焦点検出部は、認識部により認識された被写体像の特徴に適した方法で焦点ずれ量の検出を行う。
