  • Patent number: 10859790
    Abstract: A focusing apparatus includes processing circuitry. The processing circuitry is configured to select an AF area indicating a defocus amount closest to a calculated moving object prediction equation among the latest defocus amounts detected for the plurality of AF areas, in a case where the moving object prediction equation is determined as being established, and the driving direction is determined as being the close-range direction. The moving object prediction equation is determined as being established when a divergence amount between the defocus amount equal to or larger than a predetermined number included in the history and the calculated moving object prediction equation is equal to or lower than a predetermined value.
