Patent number: 7995138Abstract: Maximum and minimum aperture sizes are regulated with regard to a diaphragm in order to secure predetermined optical capability in an optical unit which includes a taking lens and the diaphragm. In normal taking, the diaphragm is used within a normal taking range from the maximum to the minimum aperture sizes. In the present invention, an aperture size which is larger than the maximum size and a size which is smaller than the minimum size (extra aperture size or extra small size) are respectively set at outside the range that secures the capability. The aperture sizes of the diaphragm at outside the specified range are used at least for one of the following: automatic exposure (AE) adjustment, auto focus (AF) adjustment, electronic zoom, displaying a moving image, taking for recording the moving image, and taking under a low resolution by thinning out pixels.Type: GrantFiled: August 17, 2007Date of Patent: August 9, 2011Assignee: Fujifilm CorporationInventors: Akihisa Yamazaki, Atsushi Misawa, Shigeru Kondo, Michitaka Nakazawa

Publication number: 20090087172Abstract: A focal point detection device capable of good focal position detection even when the focus lens is displaced due to impact, and an image capture device. During focal point detection, when focal point detection is impossible, whether AF evaluation values decrease continuously is determined, and whether impact has occurred is detected when decreasing continuously. The focus lens is moved to the initial position when AF evaluation values decrease continuously and impact is detected, as the focus lens is possibly displaced. After the focal point detection is performed again and it is determined whether it is possible to detect the focal point, the focus lens is moved to the focal position when focal point detection is possible, and the focus lens is moved toward the nearside when focal point detection is not possible, on the basis that the photographic subject has been image captured outside of the set image capture range.Type: ApplicationFiled: September 16, 2008Publication date: April 2, 2009Applicant: FUJIFILM CORPORATIONInventors: Michitaka NAKAZAWA, Akihiro Maejima, Shigeru Ichikawa
