Abstract
(EN)
Provided are a device and method which are capable of auto-focus (AF) processing with high accuracy during the operation of a focus lens or a zoom lens. This interchangeable lens acquires position information on the focus lens and the zoom lens at a prescribed time interval within an exposure period of a wave detection information acquisition pixel which is used for calculating a defocused amount (DF), and outputs the acquired position information to an image capturing device. The image capturing device calculates the defocused amount (DF) by using information on the wave detection information acquisition pixel, calculates a reference focus lens position (Ref_fc) by using a correspondence point, of the input lens position information, to a cam curve, and calculates a target focus lens position (Tgt_fc), which becomes a focusing position, from the reference focus lens position (Ref_fc) and the defocused amount (DF) to output the focusing position to the interchangeable lens.

L'invention concerne un dispositif et un procédé qui sont capables d'effectuer un traitement d'autofocus (AF) avec une haute précision pendant le fonctionnement d'un objectif de mise au point ou d'un objectif de zoom. Cet objectif interchangeable acquiert des informations de position sur l'objectif de mise au point et l'objectif de zoom à un intervalle de temps prédéterminé durant une période d'exposition d'un pixel d'acquisition d'informations de détection d'onde qui est utilisé pour calculer une quantité défocalisée (DF), et fournit les informations de position acquises à un dispositif de capture d'image. Le dispositif de capture d'image calcule la quantité défocalisée (DF) en utilisant des informations sur le pixel d'acquisition d'informations de détection d'onde, calcule une position d'objectif de mise au point de référence (Ref_fc) en utilisant un point de correspondance, des informations de position d'objectif d'entrée, avec une courbe de came, et calcule une position d'objectif de mise au point cible (Tgt_fc), qui devient une position de mise au point, à partir de la position d'objectif de mise au point de référence (Ref_fc) et de la quantité défocalisée (DF) pour fournir la position de mise au point à l'objectif interchangeable.

フォーカスレンズやズームレンズの動作中でも高精度なオートフォーカス(AF)処理を可能とした装置、方法を提供する。交換レンズはデフォーカス量(DF)算出に利用する検波情報取得画素の露光期間内に、所定時間間隔でフォーカスレンズとズームレンズの位置情報を取得して撮像装置に出力する。撮像装置は検波情報取得画素情報を利用してデフォーカス量(DF)を算出し、入力したレンズ位置情報のカムカーブの対応点を利用して基準フォーカスレンズ位置(Ref_fc)を算出し、基準フォーカスレンズ位置(Ref_fc)と、デフォーカス量(DF)から、合焦位置となるターゲットフォーカスレンズ位置(Tgt_fc)を算出して交換レンズに出力する。
