Patent number: 8106992Abstract: A taking lens 10 of an automatic focusing system of an optical path length difference type is configured so that AF object light is branched from a main optical path that guides object light to a video imaging device 26 of a camera main body 14, and object images are formed on AF imaging devices 22A and 22B. A ? type CCD is used as the video imaging device 26, and a ? type CCD, that is easily available and cheap, is used as the AF imaging devices 22A and 22B. In view of that sizes of the AF imaging devices 22A and 22B are smaller than that of the video imaging device 26, the object images formed on the AF imaging devices 22A and 22B are reduced by a reduction optical system 17.Type: GrantFiled: January 24, 2008Date of Patent: January 31, 2012Assignee: Fujinon CorporationInventor: Atsushi Kanayama

Patent number: 7860385Abstract: When it is detected that a tracking target disappears in an image range in the course of tracking the tracking target, which is a registration pattern selected as a target to be tracked from among registration patterns, an autofocus is disabled. Thereafter, the autofocus is kept being disabled even if it is detected that the tracking target having the selected registration pattern appears in the image range. Alternatively, when the tracking target disappears in the image range in the course of tracking the tracking target, the autofocus is disabled, and thereafter when the tracking target having the registration pattern appears in the image range, it is started to track the tracking target having the registration pattern.Type: GrantFiled: February 13, 2009Date of Patent: December 28, 2010Assignee: Fujinon CorporationInventor: Atsushi Kanayama

Patent number: 7345706Abstract: Auto focus control is exerted based on a focus evaluation value indicating a degree of sharpness of an image obtained from a plurality of image pickup devices placed at positions of different light path lengths. There is provided a device which makes a correction on sensitivity of the focus evaluation value obtained from each image pickup devices. It is thereby possible to make an adequate correction on a sensitivity of the focus evaluation value so as to exert the auto focus control with high accuracy. It is also possible to automatically make a correction on the sensitivity of the focus evaluation value and eliminate troublesome labor. All or a part of signal processing for the auto focus control is performed by a single processing part by time-sharing. Thereby, a circuit scale can be miniaturized and power consumption can be reduced.Type: GrantFiled: August 18, 2003Date of Patent: March 18, 2008Assignee: Fuji Photo Optical Co., Ltd.Inventors: Atsushi Kanayama, Tadashi Sasaki
