Abstract:
(EN) Provided are a focus adjustment device, a camera system, and a focus adjustment method that can make corrections so as to achieve an accurate conversion coefficient. A two-image spacing value (image phase-difference information) is calculated on the basis of image data from focus-detection pixels in an imaging element (201), a defocus amount y is calculated by a CPU inside a body control unit (203) (S5), a lens drive amount is calculated, and a lens is driven (S7). Thereafter, the conversion coefficient for the calculation of the defocus amount is corrected by a learning algorithm (S9).
(FR) La présente invention porte sur un dispositif de mise au point du foyer, un système de caméra et un procédé de mise au point du foyer qui peuvent réaliser des corrections de manière à atteindre un coefficient de conversion précis. Une valeur d'espacement de deux images (informations de différence de phase d'image) est calculée sur la base de données d'image provenant de pixels de détection de foyer dans un élément (201) d'imagerie, une quantité de défocalisation y est calculée par une unité centrale de traitement (CPU) à l'intérieur d'une unité (203) de commande de corps (S5), une quantité d'entraînement d'objectif est calculée et un objectif est entraînée (S7). Par suite, le coefficient de conversion pour le calcul de la quantité de défocalisation est corrigé par un algorithme d'apprentissage (S9).
(JA) 個々の焦点調節装置において正確な変換係数となるように補正が可能な焦点調節装置、カメラシステム、および焦点調節方法を提供する。撮像素子201の焦点検出用画素からの画像データに基づいて、2像間隔値(像位相差情報)を算出し、本体制御部203内のCPUはデフォーカス量yを算出し(S5)、レンズ駆動量を算出し、レンズ駆動を行う(S7)。この後、学習アルゴリズムにより、デフォーカス量の算出のための変換係数を補正する(S9)。
