Patent number: 7620308Abstract: In order to carry out relatively accurate AF control while eliminating the adverse effect on a reproduced moving picture, a subject is imaged every 1/30 seconds, so that subject images are obtained. Image data representing the subject images respectively corresponding to odd-numbered frames are recorded on a memory card as image data representing the moving picture. At timing where the subject images respectively corresponding to even-numbered frames are obtained by the imaging, auxiliary light is irradiated onto the subject. A high-frequency component is extracted from the image data representing each of the subject images respectively corresponding to even-numbered frames, so that focusing data representing the degree of focusing of the subject image is obtained. Since the subject image used for focusing control is bright, focusing control can be carried out relatively accurately.Type: GrantFiled: December 7, 2006Date of Patent: November 17, 2009Assignee: Fujifilm CorporationInventor: Daisuke Itoh
