INTERCHANGEABLE LENS DIGITAL CAMERA

摘要

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.

主权项

1. An interchangeable lens digital camera comprising an interchangeable lens, a camera body, to which the interchangeable lens is detachably attachable, and communication units which are electrically connected by attaching the interchangeable lens to the camera body, enabling communication between the interchangeable lens and the camera body, wherein,
A. the interchangeable lens comprises: a shake detection sensor that detects the direction and amount of a shake of the interchangeable lens; a shake compensation device that moves a shake compensation lens located in the light path so as to compensate for the shake on the basis of the direction and amount of the shake; and a lens controller that transmits deviation information based on the direction and amount of the shake to the camera body through the communication unit; B. the camera body comprises: an image sensor having a plurality of pixels arranged in a matrix to image a subject and output an image signal; an image data processor that produces a live view image from the image signal, for displaying the live view image on an image display unit; and a body controller for controlling the camera body; C. the communication unit comprises: a serial communication unit for serial communication of information between the lens controller and the body controller; and a condition communication unit for communication of condition informing signals, which represent conditions of the interchangeable lens and the camera body, between the lens controller and the body controller, wherein the lens controller and body controller transmit and receive the deviation information through one of the serial communication unit and the condition communication unit.
