Abstract:
(EN) A CPU executes a zoom-tracking control program to acquire a focal length of an imaging lens from the state of a zoom lens. Further, the CPU performs a first control to change the position of a focus lens along the optical axis in accordance with the focal length acquired, on the basis of a zoom tracking curve shown by tracking data that represents the correspondence relationship between the focal length and the focus position according to a subject distance, and a second control to acquire contrast information that represents the contrast of a captured image a plurality of times during the first control to change the zoom tracking curve for use in the first control on the basis of a change in the contrast value represented by each of a plurality of pieces of contrast information acquired.
(FR) Selon la présente invention, une unité centrale de traitement (CPU pour Central Processing Unit) exécute un programme de commande de suivi de zoom pour acquérir une longueur focale d'une lentille d'imagerie à partir de l'état d'une lentille de zoom. En outre, l'unité CPU exécute une première commande pour modifier la position d'une lentille de mise au point le long de l'axe optique en fonction de la longueur focale acquise, sur la base d'une courbe de suivi de zoom représentée par des données de suivi qui représentent la relation de correspondance entre la longueur focale et la position de mise au point selon une distance de sujet, et une seconde commande pour acquérir des informations de contraste qui représentent le contraste d'une image capturée une pluralité de fois pendant la première commande pour modifier la courbe de suivi de zoom pour une utilisation dans la première commande sur la base d'un changement de la valeur de contraste représentée par chaque élément d'informations de contraste d'une pluralité d'éléments d'informations de contraste acquises.
(JA) CPUは、ズームトラッキング制御プログラムを実行することによりズームレンズの状態から撮像レンズの焦点距離を取得する取得部と、被写体距離に応じた、焦点距離とフォーカス位置との対応関係を表すトラッキングデータが示すズームトラッキング曲線に基づいて、取得した焦点距離に応じてフォーカスレンズの光軸方向に沿った位置を変化させる制御を行う第1制御、及び第1制御の実行中に撮像画像のコントラストを表すコントラスト情報を複数回取得し、取得した複数のコントラスト情報の各々によって表されるコントラスト値の変化に基づいて、第1制御に用いるズームトラッキング曲線を変更する制御を行う第2制御を行う制御部として機能する。
