IMAGING APPARATUS, METHOD FOR CONTROLLING THE SAME, AND STORAGE MEDIUM STORING PROGRAM

摘要

An imaging apparatus that performs continuous imaging, includes: a focus detection unit that perform focus detection and calculates an amount of defocus in each of a plurality of imaging operations; a position detection unit that detects an image plane position corresponding to a subject position using the amount of defocus; an estimation unit that estimates a next image plane position using a plurality of pairs of data regarding the image plane position and a time at which the amount of defocus has been detected; and a turnabout determination unit that determines whether a subject is a turnabout subject, which is a subject that moves towards the imaging apparatus, changes direction of movement, and then moves away from the imaging apparatus. The number of pairs of data used for the estimation decreases based on a ratio of a highest image plane speed in past scenes to a current image plane speed.

主权项

1. An imaging apparatus that performs continuous imaging, in which a plurality of imaging operations are successively performed, the imaging apparatus comprising:
a focus detection unit configured to perform focus detection, in which an amount of defocus is detected; a position detection unit configured to detect an image plane position corresponding to a subject position using the amount of defocus; an estimation unit configured to estimate a next image plane position using a plurality of pairs of data regarding the image plane position and a time at which the amount of defocus has been detected; and a turnabout determination unit configured to determine whether a subject is a turnabout subject, which is a subject that moves towards the imaging apparatus, changes direction of movement, and then moves away from the imaging apparatus, wherein, if the turnabout determination unit determines that the subject is a turnabout subject, the estimation unit takes more into account latest data than when the turnabout determination unit has determined that the subject is not a turnabout subject.
