Abstract

An image blur correcting apparatus is controlled in accordance with panhead data signals received from a panhead apparatus to save energy while compensating the performance of the panhead apparatus with an image blur correcting function of the image blur correcting apparatus. The panhead apparatus outputs a variety of panhead data signals such as a panhead identification signal representing the type of the panhead apparatus, a signal representing the panning or tilting operation, a signal representing a panning or tilting speed, and a signal representing a panning or tilting position. The image blur correcting apparatus receives the panhead data signals through a signal transmission part, and automatically turns on or off the image blur correcting function and adjusts a sensitivity, in accordance with the performance of the panhead apparatus and the panning/tilting speed and/or positions.

Claims

1. An image blur correcting apparatus for correcting an image blur resulting from a vibration of a camera, the image blur correcting apparatus comprising:

a signal receiver for receiving a panhead data signal outputted from a panhead apparatus on that the camera is mounted; and

a controller for turning on and off an image blur correcting function of the image blur correcting apparatus in accordance with the panhead data signal received through the signal receiver.

2. The image blur correcting apparatus as defined in claim 1, wherein the image blur correcting apparatus moves a correcting lens within a plane perpendicular to an optical axis to thereby correct the image blur.

3. An image blur correcting apparatus for correcting an image blur resulting from a vibration of a camera, the image blur correcting apparatus comprising:

a signal receiver for receiving a panhead data signal outputted from a panhead apparatus on that the camera is mounted; and

a controller for adjusting a vibration sensitivity of the image blur correcting apparatus in accordance with the panhead data signal received through the signal receiver.

4. The image blur correcting apparatus as defined in claim 3, wherein the image blur correcting apparatus moves a correcting lens within a plane perpendicular to an optical axis to thereby correct the image blur.
