<p>PURPOSE:To provide a new image blurring preventing device capable of preventing the image blurring by the vibration of a subject to be observed, or the vibration of an object itself. CONSTITUTION:As for the image blurring preventing device, the image blurring on an image pickup element 5 is prevented by detecting the movement of a line of sight by an observer 100 by a means for detecting the line of sight (constituted of a light source 104, a lens 106, half mirrors 105 and 105', a lens 107, an image sensor 109 and a line of sight detection circuit 10) installed on an observation optical system for the optical device, by detecting the shake and vibration of the subject to be observed based on the outputted signal so as to calculate the correction driving quantity of an image blurring correcting lens 3 for a master optical system by a vibration correcting means control circuit 11, thereafter, by driving an actuator 3a through an actuator driving circuit 12 so as to move the lens 3.</p> |
