Image-pickup apparatus
摘要:
An image-pickup apparatus includes an image-pickup element photoelectrically converting an object image, a light-receiving sensor outputting a signal in accordance with a phase difference between a pair of object images, and a controller performing first focus control of controlling drive of a focus adjusting member based on a focus evaluation signal representing a contrast state of a video signal produced with the image-pickup element and second focus control of controlling drive of the focus adjusting member based on the signal in accordance with the phase difference. The controller stops the second focus control or switches focus control from the second focus control to the first focus control in response to a predetermined change found in the focus evaluation signal during the second focus control. The apparatus is capable of achieving an in-focus state smoothly and accurately with a hybrid AF.
