摘要： 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.

摘要： An imaging apparatus includes a photographic lens, an imager, a diaphragm, a drive unit, and a control unit. The imager receives light fluxes passing through the photographic lens to generate an imaging signal. The diaphragm regulates the light fluxes passing through the photographic lens and received by the imager. The drive unit drives the diaphragm. The control unit performs still image continuous photography and displays a live-view image on a display unit during each main exposure of the still image continuous photography. The control unit controls a start timing of the driving of the diaphragm for the main exposure performed by the drive unit while the live-view image is displayed during each main exposure of the still image continuous photography, in accordance with a drive speed of the diaphragm.
