摘要:
An image taken by a mobile camera is displayed on a head-mounted display provided with an acceleration sensor to detect movement of the observer's head, and the size of the image viewed by the observer wearing the display is varied according to the movement of the observer's head. For varying the image size, the camera is equipped with a zoom lens to change the size of shooting area, or alternatively, the display is equipped with a zoom lens as the eyepiece to enlarge or reduce the size of the displayed image. An image showing the appearance of the camera is displayed being superimposed on the image taken by the camera in order to facilitate the control of the camera by the observer.

An HMD is provided with two piezoelectric vibrating gyros which detect vertical and horizontal angular velocities, and a horizontal sensor which detects a vertical angle. While the user's head rotates, shooting direction of a three-dimensional camera is varied in accordance with the angles obtained by integration of the detected angular velocities. While the head is stationary, the obtained vertical angle and the output of the gyro is corrected based on the angle detected by the horizontal sensor. The shooting direction of the camera can be manually set irrespective of the direction of the head, and information on the viewing direction is displayed together with a taken image.

A movable stage utilizing an electromechanical transducer. An actuator as a drive source thereof is composed of piezoelectric elements, drive member fixed thereto and a movable member friction-coupled with the drive member. When a drive pulse is applied to the piezoelectric element to cause it to show reciprocal displacements at different rates in the thickness direction, the movable member frictionally coupled with the drive member moves in the predetermined direction to move the movable table coupled with the movable member in the predetermined direction. The movable stage comprising the movable table moving in the two axes or three axes can be constituted by providing the actuator in the two axes or three axes crossing with each other.

An optical device having a dioptric correction device comprises a reference image display unit which is placed in the optical path extending from an object image to the optical system. The reference image is used for dioptric correction. The left and right reference images are different and are displayed on the left and right reference image display units when dioptric correction is performed. The reference image display unit is placed at a predetermined position between the optical system and an image display unit. Since the reference image is positioned at the predetermined position, both of the image of the image display unit and the reference image may be seen clearly.

In a stereoscopic system including a three-dimensional camera and an HMD, by setting the convergences of the three-dimensional camera and the HMD in accordance with the distance to the object to be shot, a stereoscopically viewable object distance range is increased and a natural stereoscopic image is provided. The three-dimensional camera is provided with a convergence setter which varies the directions of left and right cameras, and the HMD is provided with a convergence setter which varies the directions of left and right virtual image projectors. The distance to the object is detected based on the distance between the left and right images taken by the three-dimensional camera, and the convergence setters of the three-dimensional camera and the HMD are controlled in accordance with the detected distance. The convergence setter of the three-dimensional camera performs focusing, interlocking with the convergence setting. The convergence setter of the HMD sets the dioptric power, interlocking with the convergence setting.

A display device provides a virtual image for eyes of an observer. The display has a light source which emits light based on an image signal, scanner which scans the light, an eyepiece optical system which projects the scanned light onto an eye of the observer as a virtual image, detector which detects a pupil size of the observer, and regulator means which regulates a quantity of light projected onto the eye of the observer based on the detected pupil size.
摘要:
An apparatus and method of adjusting an auto focus are provided. The apparatus includes: an imaging pickup device for generating an image signal by capturing light passing through an imaging lens; a shutter for controlling light exposure of the image pickup device; a focus detector that calculates a contrast value from the image signal and detecting a focus from the contrast value; and a release controller for controlling a release operation constituting a photographing operation of a still image, wherein the release controller includes, as driving modes, a first mode that directs a focus lens included in the imaging lens to be driven while driving the shutter, and a second mode that directs the focus lens not to be driven while driving the shutter. Accordingly, a photographing time is reduced.
