Autofocusing system for camera
摘要:
An autofocusing system for a camera, wherein a defocus amount is detected with a light-amount-integration type detector for performing a focusing operation. The focusing operation is adjusted in a predetermined fashion if it is determined that a photographic lens has moved and/or the focal length of the photographic lens has varied while the light-amount-integration is being executed.
