Patent number: 5819119Abstract: A camera with a visual line position detection device is capable of shortening the time required for auto focus detection and capable of more accurate selection of the focus detection point. The camera includes a focus detection device to output the results of distance measurements at a plurality of points where focus detection is possible and to detect focus for one of these points. A liquid crystal display device displays on a screen specified symbols overlapping the subject image on the positions corresponding to each of the points. A microprocessor accepts the results of the distance measurements from the focus detection system and selects one of the points based on the photographer visual line position as the point for focus detection among all the points whose distances are measured and on which focus detection is possible, excluding the points with an infinite focus distance.Type: GrantFiled: January 31, 1997Date of Patent: October 6, 1998Assignee: Nikon CorporationInventors: Kazuharu Imafuji, Hidehiro Ogawa, Toru Kosaka, Yoshio Matsuzawa

Patent number: 5727234Abstract: A camera is provided that accomplishes a warning display using a range measurement frame indicating a specific subject field region. The camera includes a shake amount detection system that detects the amount of shaking of the camera, a drive system that drives the correction lens to effect shake correction and a movement amount detection system that detects the amount of movement of the correction lens. The camera may also include a lens MPU and a camera MPU. The lens MPU determines whether or not shaking has been negated through driving of the correction lens accomplished by the drive system. When shaking has not been negated, the lens MPU outputs a warning signal. The camera MPU sends a signal to the warning display system upon receiving this output warning signal to cause a range measurement frame to flash.Type: GrantFiled: March 23, 1995Date of Patent: March 10, 1998Assignee: Nikon CorporationInventors: Yasushi Sakagami, Yoshio Matsuzawa

Patent number: 5159364Abstract: There is disclosed a camera equipped with a mode setting device which counts the number of uses of each of plural modes, and sets the most frequently used mode as the initial mode. At the phototaking operation, the camera is set at such most frequently used mode. The above-mentioned plural modes can be plural exposure control modes, focal length control modes, photographing magnification setting modes, self-timer modes, automatic exposure value correcting modes, or alarm modes.Type: GrantFiled: August 12, 1991Date of Patent: October 27, 1992Assignee: Nikon CorporationInventors: Masaaki Yanagisawa, Tetsuro Goto, Naoki Tomino, Tsutomu Wakabayashi, Yoshio Matsuzawa, Kazuyuki Kazami, Koichi Daitoku, Akira Ezawa, Toshio Sosa, Kazuto Otsuka, Hideya Inoue

Patent number: 5130735Abstract: An automatic focus state detecting apparatus is capable of focus detection with respect to an object in different focus state detection areas, such as a narrow area or a wide area of an object field, or in areas extending in different directions in the object field. The focus state detecting area may be selected automatically or manually, and the automatic selection may depend upon whether the object is stationary or moving, and the direction of movement. Automatic switching between narrow and wide focus state detecting areas may occur after an in-focus state or a nearly in-focus state is obtained in the narrow area, after a predetermined time has elapsed from the selection of the narrow area, or after a predetermined number of focus detecting operations in the narrow area. Defocus amounts may be calculated for a plurality of sub-areas of the wide area. The defocus amount or a lens driving amount may be limited when the wide area is selected.Type: GrantFiled: September 12, 1991Date of Patent: July 14, 1992Assignee: Nikon CorporationInventors: Yosuke Kusaka, Yoshio Matsuzawa, Masaru Muramatsu

Patent number: 4318603Abstract: A film rewind device in a camera in which a rewind coupling is automatically engaged with a cassette shaft in response to rewind operation has a rotatable member having a spiral groove on its peripheral wall portion and said rewind coupling at the end of the shaft thereof, the rotatable member being slidable in axial direction and rotatable by rewind operation, and a meshing member meshing with the spiral groove at the initial stage of the rewind operation to thereby slide the rotatable member in axial direction to cause the coupling to engage the cassette shaft. The mesh engagement between the meshing member and the spiral groove is released in axial direction when the coupling engages the cassette shaft, so that the meshing member comes to support the rotatable member so as to block the return of the rotatable member in axial direction.Type: GrantFiled: March 28, 1980Date of Patent: March 9, 1982Assignee: Nippon Kogaku K.K.Inventors: Koichi Daitoku, Hatsuo Sakamoto, Nobuhiko Terui, Toshiaki Hozumi, Yoshio Sekine, Yukio Hyodo, Masanori Ichikawa, Masamichi Wada, Tsuyoshi Kudo, Manabu Nakamura, Nobuaki Nakanishi, Takeo Komai, Yoshio Matsuzawa
