发明名称 PHOTOMETRIC DEVICE FOR CAMERA PROVIDED WITH AUTOMATIC FOCUSING FUNCTION
摘要 PURPOSE:To always obtain appropriate exposure in accordance with composition by automatically performing multiphotometry in which the main object is always weighted by means of obtaining the position of a main object on a photographic image plane after a camera or the main object moves even if the camera or the main object moves at the time of photographing. CONSTITUTION:At the time of photographing, the camera is set at a 1st position where the main object 20 is positioned in the center of the photographic image plane 10 to perform initial multiphotometry where AF and the main object 20 are weighted. Thereafter, when the camera moves, for example, the moving position of the main object 20 on the photographic image plane 10 is obtained. Then, the multiphotometry where the main object 20 is weighted is performed again at a 2nd position newly obtained. Thus, photographing is performed under the optimum exposing condition even after moving the camera.
