Abstract

See full text

A CPU detects an image displacement amount using a signal acquired from an image sensor and converts a defocus amount using a conversion factor. The CPU predicts a future image-plane position of a moving object based on data on the defocus amount, time and a lens position. The CPU corrects the conversion factor using the data. The CPU predicts the future image-plane position of the moving object using the corrected conversion factor.
