Patent number: 9838589Abstract: An imaging apparatus including an exchangeable lens and a camera body. The camera body transmits a synchronizing signal having the same cycle as the cycle of the capturing operation in the imaging unit, to the interchangeable lens. The controller of the exchangeable lens performs a zoom tracking control by determining the focus position of the focus lens from the position of the zoom lens detected by the position detector by referring to the relation information, and controlling the focus lens driver to move the focus lens to the determined focus position, The controller performs the zoom tracking control in a cycle (for example, one-eighth) shorter than a cycle indicated by the synchronizing signal received from the camera body.Type: GrantFiled: October 21, 2016Date of Patent: December 5, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Naotaka Kishida, Yasuhiro Shingu

Patent number: 7697030Abstract: A monitor camera is provided with a control device which carries out a predetermined process in response to an input of a trigger signal. The control device has an arrangement in that continuous images are successively inputted from a camera unit thereto and in that a detection of a moving object is carried out by detecting a change in images in a moving-object detector. When no change in images is detected by the moving-object detector within a predetermined time after the input of a trigger signal from a detection sensor to a trigger signal input unit, the control device determines the trigger signal inputted to the trigger signal input unit as valid. Then, only when the valid trigger signal has been detected, an abnormality process is carried out. Consequently, it is possible to prevent the abnormality process from being performed upon erroneous detection of a normal state as an abnormal state.Type: GrantFiled: December 10, 2003Date of Patent: April 13, 2010Assignee: Konica Minolta Holdings, Inc.Inventors: Tomoyuki Terada, Masaru Sawada, Naotaka Kishida, Ayumi Itoh
