Abstract
An imaging apparatus moves a focus lens on the basis of an imaging signal of an image pickup device to perform a focal adjustment. The image pickup device images a subject. The imaging apparatus includes an evaluation value calculation circuit, a control circuit, and a movement determination circuit. The evaluation value calculation circuit extracts a predetermined signal component from an imaging signal to generate an evaluation value. The control circuit performs a focal adjustment on the basis of the evaluation value. The movement determination circuit determines whether or not the subject or the imaging apparatus is moving. The control circuit changes a frame rate of the image pickup device from a first frame rate to a second frame rate higher than the first frame rate when the movement determination circuit determines that the subject or the imaging apparatus is moving.
