  • Patent number: 9973676
    Abstract: Provided is an interchangeable lens digital camera that is capable of correcting a rolling shutter distortion in a live view image without delay in displaying the image. At the start of live view imaging, a lens controller in an interchangeable lens controls a shake detection sensor to detect the direction and amount of a shake, and produces deviation information on the basis of shake detection signals from the shake detection sensor, the deviation information indicating fluctuation in direction and amount of the shake for one frame of the live view image in the form of a parameter. The deviation information is transmitted to a body controller of a camera body through a serial communication unit, to correct the rolling shutter distortion on the basis of the deviation information.

  • Patent number: 9794458
    Abstract: A camera system, a camera body, and a communication method capable of satisfactorily acquiring lens information necessary for image processing or the like for a frame of a video from an interchangeable lens are provided. Three-wire serial communication is performed in which a request signal is transmitted to the interchangeable lens in synchronization with a synchronization signal (VSYNC) of an imaging element in a video recording mode, and a response signal is received from the interchangeable lens. In a communication mode in the video recording mode, the number of transmissions of a first request signal relating to acquisition of lens information such as a focus position, a diaphragm value, and a zoom position is limited. Accordingly, communication other than communication relating to acquisition of lens information can be performed in a period of one frame.
