Abstract

The embodiment of the invention provides an automatic focusing method and an automatic focusing system. The method comprises the steps of obtaining and confirming a human eye image of a photographer, calculating a human eye sight direction corresponding to the human eye image by utilizing a human eye tracking technique, calculating coordinates of a human eye sight of the photographer on a viewfinder according to the human eye sight direction, and focusing photographed bodies corresponding to the coordinates. The automatic focusing method achieves flexible setting of focusing positions of the photographed bodies, and accurate, low-cost and easy-to-maintain automatic focusing.

Description

technical field [0001] The present invention relates to the technical field of focusing, and more specifically relates to an automatic focusing method, system, camera and video camera with the system. Background technique [0002] With the popularization of cameras, the focus technology closely related to camera imaging technology has also been developed unprecedentedly, among which the auto focus technology is the most typical. The focusing principle of a camera using auto-focus technology (also called an auto-focus camera) is as follows: According to the principle of light reflection, the photosensitive device on the camera receives the reflected light from the subject, and the received light information is processed by the computer on board, and then the Motorized focusing device for focusing. [0003] When shooting with an auto-focus camera, photographers often require that the focus position of the subject can be set at different positions in the viewfinder, so as to o...
