发明名称 AUTOMATIC FOCUSING CAMERA
摘要 PROBLEM TO BE SOLVED: To realize an automatic focusing action on a visible-light film by infrared rays and the excellent photographing action of a picture by the infrared rays even when an interchangeable lens which is not provided with the correction data of the infrared rays is attached. SOLUTION: This camera is provided with a 1st focus detection means detecting a focus by using the infrared rays, a 2nd focus detection means detecting the focus by using visible light and an arithmetic means calculating the correction data for executing the focusing action on a film surface by the visible light when the 1st focus detection means is used. Then, the arithmetic means is constituted so that the correction data are calculated (S202-S204) by using the detected result of the focus by the 1st focus detection means and the detected result of the focus by the 2nd focus detection means.
