An image pickup unit picks up an image of an object and a driving unit drives a focus lens in an optical axis direction. A control circuit controls a focus state of the object by causing the driving unit to move the focus lens in the optical axis direction. A focus evaluation value is acquired from each image. The control circuit causes the image pickup unit to pick up images of a multistage exposure image group by changing exposure time, selects an image according to exposure time, updates a direction of driving the focus lens using the focus evaluation value acquired from the selected image, and causes the driving unit to move the focus lens in the updated driving direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus that periodically changes exposure condition, a method of controlling image pickup apparatus, and storage medium","description":"An image pickup apparatus capable of performing proper image evaluation in photographing a moving image by changing the exposure condition.
