发明名称 AUTOMATIC FOCUSING CAMERA
摘要 PURPOSE:To realize photographing in focus even when a moving body is consecutively photographed by a camera by changing the calculating system for a correction driving amount between before exposing a 1st frame and before exposing the second and succeeding frames. CONSTITUTION:By receiving output from a focus detection means 101, the amount concerning the movement of an image-formation surface associated with the movement of the object in an optical axis direction is calculated and the correction driving amount for attaining a focusing state at the time of exposing is calculated, and the calculating system for the correction driving amount is changed between before exposing the 1st frame and before exposing the 2nd and succeeding frames by a consecutive photographing means by a correction means 100. Based on the calculated result by the correction means 100, a lens driving means 104 is controlled by a control means 102. Since the system for calculating the correction driving amount for aligning a film surface with the image surface of the object at the time of exposing is changed between before exposing the 1st frame and before exposing the 2nd and succeeding frames, photographing in focus is realized even in the case of the 1st frame and the 2nd and succeeding frames consecutively photographed.
