摘要： The object is to provide an image viewing system that allows easy image viewing with reduced eyestrain, whether for wide-angle or enlarged viewing. The rotation of the viewer's head is detected by means of piezo-electric vibration gyroscopes 405 and 406, and the coefficient for setting the amount of change in the camera system's image shooting direction with reference to the detected direction is changed in accordance with the focal length of the camera system's zoom lens systems. Moreover, the amount of change in the image shooting direction may be changed manually by means of sensitivity setting lever 213 mounted on HMD 2.

摘要： An image observation device which is so arranged that a user can look an image in through an ocular window thereof with the device being fitted to the user's head for example, that the image changes in linkage with movement of the user's head, and that unnecessary change of the image is prevented during the observation. The image observation device includes an eye access detector for detecting whether the user's eyes approach thereto or not, and includes, a controller by the operation of which the image changes in linkage with movement of the user's head only if the eye access detector detects that the user's eyes approach thereto, and by the operation of which the image does not change in linkage with movement of the user's head if the eye access detector does not detect that the user's eyes approach thereto.
