Imaging device with lens barrell information communications

摘要

An imaging device is provided that includes a camera body, a lens barrel, a lens barrel information transmitter, and an image sensor driver. The image sensor is housed in the camera body. The lens barrel is attachable to and detachable from the camera body. The lens barrel information transmitter regularly transmits information of the lens barrel to the camera body. The image sensor driver drives the image sensor at one of at least two different frame rates where a second frame rate is higher than a first frame rate. The amount of data being transmitted is reduced by the lens barrel information transmitter when the image sensor is driven at the second frame rate, compared to the amount transmitted when the image sensor is driven at the first frame rate.

1. An imaging device comprising:
a camera body provided with an image sensor; a lens barrel attachable to and detachable from the camera body; a lens barrel information transmitter regularly transmitting information representing the status of the lens barrel to the camera body; and an image sensor driver driving the image sensor at one of at least two different frame rates where a second frame rate is higher than a first frame rate; wherein the amount of data being transmitted for the information representing the status of the lens barrel is reduced throughout the time that the image sensor is driven at the second frame rate, compared to the amount transmitted when the image sensor is driven at the first frame rate, while the regular transmission of the information representing status of the lens barrel to the camera body continues.
