摘要： A focus area contains one or more areas, into which an image signal captured by an image sensor (14) is segmented by an image segmentation section (15). The focus area follows movement of an object in accordance with feature point positional information of an image extracted by a feature point extraction section (34) and a feature point positional calculation section (35). Further, after a low-pass filter (36) extracts a low frequency component of a time-series oscillation frequency using the feature point positional information, and a focus area selection section calculates a display position, the focus area is displayed on a display section (17). Therefore, an imaging device, which does not cause discomfort even when the focus area displayed on the display section (17) fluctuates by tracking movement of the object, is provided.

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.

摘要： A camera system includes a camera body (100) and an interchangeable lens (200). The camera body includes an imaging unit that captures a subject image formed by the interchangeable lens in a predetermined capturing cycle to generate image data, a body controller that generates a synchronizing signal having a first cycle correlated with the capturing cycle, and a sending unit that sends the generated synchronizing signal to the interchangeable lens. The body controller further sends information indicating a second cycle different from the first cycle to the interchangeable lens. The interchangeable lens includes a focus lens (230), a drive unit (233) that drives the focus lens along an optical axis, a receiving unit (250) that receives the synchronizing signal and the information indicating the second cycle sent from the camera body, and a lens controller (240) that controls an operation of the interchangeable lens. The lens controller controls the drive unit to perform, in the second cycle, a minute back and forth driving which minutely moves the focus lens back and forth along the optical axis, and performs other control in the first cycle in the interchangeable lens than the control of the minute back and forth driving.

摘要： In a camera system including an interchangeable lens and a camera body, a lens controller performs control to detect a position of a focus lens in synchronous with a predetermined timing received from the camera body, store it in a storage unit, and transmit it to the camera body when receiving a position information request signal for requesting transmission of position information stored in the storage unit. The body controller performs control so that a timing of transmission of the position information request signal does not overlap a timing of transmission of the timing signal.
