Description

上記目的を達成するために、本発明の一態様の撮像装置は、撮像光学系により結像される光学像を受けて画像データを取得する撮像部と、上記画像データから複数の特徴部を検出する特徴検出部と、上記検出された複数の特徴部を記憶する記憶部と、新たに得られた上記画像データから得られた特徴部と記憶された上記複数の特徴部との一致をもとに、各特徴の奥行き方向の位置変化を検出すると共に、所定の時間経過後の上記複数の特徴部の位置を予測する位置変化予測部と、上記位置変化予測部によって予測される上記複数の特徴部の所定時間経過後の位置情報と上記撮像光学系の焦点距離とによって画像内の上記複数の特徴部を合焦状態とし得る被写界深度に応じた撮影制御を行う制御部とを有する。 To achieve the above object, one aspect of the imaging apparatus of the present invention includes an imaging unit that acquires image data by receiving an optical image formed by an imaging optical system, a plurality of features from the image data A feature detection unit to be detected, a storage unit that stores the plurality of detected feature units, a feature unit obtained from the newly obtained image data, and a match between the plurality of stored feature units are also included. DOO in detects a change in position of the depth direction of each feature, and the position change predicting unit for predicting a position of the plurality of features after a predetermined time has elapsed, the plurality of predicted by the position change predicting unit A control unit that performs shooting control according to the depth of field that can bring the plurality of feature units in the image into a focused state based on position information of the feature unit after a predetermined time and the focal length of the imaging optical system; .

本発明の一態様の撮像装置の制御方法は、撮像光学系により結像される光学像を受けて画像データを取得し、上記画像データから複数の特徴部を検出し、上記検出された複数の特徴部を記憶し、新たに得られた画像データから得られた特徴部と記憶された上記複数の特徴部との一致をもとに、各特徴の奥行き方向の位置変化を検出すると共に、所定の時間経過後の上記複数の特徴部の位置を予測し、上記予測される上記複数の特徴部の所定時間経過後の位置情報と上記撮像光学系の焦点距離とによって画像内の上記複数の特徴部を合焦状態とし得る被写界深度に応じた撮影制御を行う。 Multiple control method of one embodiment of an imaging apparatus of the present invention acquires image data by receiving an optical image formed by an imaging optical system to detect a plurality of features from the image data, which is the detected with the feature store, based on the match between the plurality of features that have been stored and obtained features derived from the newly obtained image data, detects the position置変of depth direction of each feature predicts the location of the plurality of features of after a predetermined time, above the image by the focal length of the position information and the imaging optical system after a predetermined time of the plurality of features to be measured above pre Shooting control is performed according to the depth of field that can bring a plurality of features into focus.
