20090167878 | IMAGE PICKUP APPARATUS, INTERCHANGEABLE LENS UNIT, CAMERA BODY, AND ULTRASONIC MOTOR DRIVING APPARATUS - An image pickup apparatus of the present invention is an image pickup apparatus including an ultrasonic motor | 07-02-2009 |
20090256950 | Imaging System and Camera Body - An imaging system includes an interchangeable lens and a camera body. The camera body includes a second communication unit capable of communicating with a first communication unit, an imaging element operable to generate an image signal from the optical image, and a main body controller operable to transmit a reference signal for providing a reference of a driving start timing of the focus lens to the lens controller through the second and first communication units. The main body controller transmits the reference signal to the lens controller during a period for which neither communication of predetermined signals other than the reference signal nor process related to the communication is performed between the first communication unit and the second communication unit. | 10-15-2009 |
20090262235 | Imaging system, camera body and interchangeable lens - An imaging system includes an interchangeable lens and a camera body. The camera body includes a main body controller operable to transmit a reference signal for providing a reference of a driving start timing of the focus lens and delay time information indicating delay time with respect to the reference signal, to the interchangeable lens. The interchangeable lens includes a lens controller operable to control the focus lens to be driven at a timing obtained by delaying the timing provided by the reference signal by the delay time based on the reference signal and the delay time information received from the main body controller. The delay time is set so that, for example, an exposure timing of a predetermined area in the imaging element is substantially coincident with a stop period of the wobbling operation of the focus lens. | 10-22-2009 |
20110063472 | CAMERA SYSTEM - A camera system includes a camera body ( | 03-17-2011 |
20110063497 | IMAGE APPARATUS SYSTEM, CAMERA BODY AND INTERCHANGEABLE LENS - An imaging apparatus system includes an interchangeable lens | 03-17-2011 |
20110080488 | CAMERA SYSTEM - The camera body includes a synchronizing signal generator that generates a synchronizing signal, a body controller that controls the camera body and generates a command to control the interchangeable lens. The body controller performs control to send the interchangeable lens a command to set the interchangeable lens to a synchronous mode in which operation of the interchangeable lens is controlled in synchronization with the synchronizing signal and a command to set the interchangeable lens to an asynchronous mode which is a mode other than the synchronous mode. The interchangeable lens includes a lens controller that controls the operation of the interchangeable lens. The lens controller controls the operation of the interchangeable lens in the synchronous mode or the asynchronous mode according to the command received from the camera body. | 04-07-2011 |

20120237194 | IMAGING SYSTEM, CAMERA BODY AND INTERCHANGEABLE LENS - An imaging system includes an interchangeable lens and a camera body. The camera body includes a main body controller operable to transmit a reference signal for providing a reference of a driving start timing of the focus lens and delay time information indicating delay time with respect to the reference signal, to the interchangeable lens. The interchangeable lens includes a lens controller operable to control the focus lens to be driven at a timing obtained by delaying the timing provided by the reference signal by the delay time based on the reference signal and the delay time information received from the main body controller. The delay time is set so that, for example, an exposure timing of a predetermined area in the imaging element is substantially coincident with a stop period of the wobbling operation of the focus lens. | 09-20-2012 |
20120262595 | FOCUSING SYSTEM, INTERCHANGEABLE LENS, AND IMAGE-CAPTURING DEVICE - A focusing system includes an optical system including first and second focus lenses for regulating a focus state of a subject image and is capable of performing a focus operation for automatically controlling the first and second focus lenses on a focus position. The focusing system includes a first drive unit for driving the first focus lens along the optical axis, a second drive unit for driving the second focus lens along the optical axis, a determining unit for periodically detecting a focus state of the subject image formed via the optical system and determining a focus position of the optical system based on the detected result, and a control unit for controlling the first and second drive units according to a result of determining the focus position of the optical system by the determining unit. The control unit controls the second drive unit to drive (such as drive at a constant speed, or stop) the second focus lens independently of the first focus lens, in the focus operation. | 10-18-2012 |
20120307131 | INTERCHANGEABLE LENS, CAMERA BODY, AND CAMERA SYSTEM - An interchangeable lens includes a focus lens for changing a focus state of an object image, a driving unit for driving the focus lens, a lens controller for controlling the driving unit so as to move the focus lens forward and backward along the optical axis at a predetermined drive frequency, and a storage unit for storing therein drive frequency information representing a drive frequency at which the driving unit can control. A camera body obtains the drive frequency information from the interchangeable lens and performs control while referring to the drive frequency information. | 12-06-2012 |
