ABSTRACT:
An auto-focusing device for a camera according to the present invention comprises many different systems. Included is a focus detection section which intermittently calculates focus detection information corresponding to the distance to the photographic subject. Also included is a photographic subject position prediction section which predicts a future position of the photographic subject based on the focus detection information. Finally, a lens driving section then drives a photographic lens based on a predicted result of the photographic subject position predicting section. The photographic subject position predicting section includes a neural network that predicts the future position of the photographic subject with an input parameter that has values regarding focusing positions of the photographic lens. These values correspond to focus detection data calculated by the focus detection section. The neural network makes it possible to predict the future focusing position of the photographic lens accurately.
