Patent number: 8436935Abstract: In an image pickup device of the present invention, in the case where a mode switch 116 selects a finder mode, a focusing lens is driven at a first speed when a focusing operation is performed in a focus control unit 203. In the case where the mode switch 116 selects a live view mode, the driving speed of the focusing lens is switched in a range lower than the first speed in accordance with brightness of an object detected by a photometric unit 114 when the focusing operation is performed in the focus control unit 203. With such a configuration, a lens driving control method is changed by AF control of a phase difference detection system and AF control of a hill climbing system, and a driving system suitable for each AF system is performed, whereby the focusing operation can be performed normally at a high speed.Type: GrantFiled: August 7, 2008Date of Patent: May 7, 2013Assignee: Panasonic CorporationInventors: Hiroshi Ueda, Kouji Shibuno, Michihiko Ootsuka

Patent number: 8251602Abstract: An intermediate adapter includes a first terminal operable to be electrically connected to a lens detecting terminal provided on the camera body when the intermediate adapter is attached to the camera body, a second terminal operable to be electrically connected to a terminal provided on the interchangeable lens for providing a ground potential when the interchangeable lens is attached to the intermediate adapter, and a first switch interposed between the first terminal and the second terminal. The first switch is operable to electrically connect the first terminal and the second terminal when the first switch is on, and disconnect the electrical connection between the first terminal and the second terminal when the first switch is off. While the intermediate adapter is being attached to the interchangeable lens, the first switch is off to disconnect the electrical connection between the first terminal and the second terminal.Type: GrantFiled: December 16, 2010Date of Patent: August 28, 2012Assignee: Panasonic CorporationInventors: Hiroshi Ueda, Koji Shibuno, Hidekazu Nakajima, Michihiko Ootsuka

Patent number: 7511757Abstract: A digital camera of the present invention includes a CMOS sensor that captures a subject image formed by an interchangeable lens to generate image data, a liquid crystal monitor that displays the generated image data, and a microcomputer having a live view mode that controls so that the generated image data is displayed as a moving image in real time on the liquid crystal monitor, and a burst mode that generates a plurality of image data with a single image pickup operation, wherein the microcomputer controls so that, in a live view mode, every time image data is generated in a burst mode, the generated image data is displayed on the liquid crystal monitor. Consequently, the generated image data is displayed on the liquid crystal monitor every time image data is generated in the burst mode, whereby the ease of use can be enhanced.Type: GrantFiled: June 19, 2007Date of Patent: March 31, 2009Assignee: Panasonic CorporationInventors: Kaoru Mokunaka, Hiroshi Ueda, Michihiko Ootsuka
