摘要： A video see through AR system capable of obtaining correct depth information with respect to each pixel representing a two-dimensional image is disclosed so that a portion of imagery which should appear in the background of a final picture may be properly hidden behind imagery which should appear in the foreground of the final picture. A photographing device is provided for obtaining a two-dimensional image of a real object field disposed in conjugate relationship with an observer's eyes. Also provided is a device for measuring distances with respect to each pixel to the real object to be measured. The measured distance is compared with the distance to virtual imagery with respect to each pixel and the pixel which represents the imagery disposed closer to the observer is selected for the formation of combined imagery, which is displayed on the screen of a display device.

摘要： A distance information generator comprises an image sensor which senses an object, a distance detector which detects a first distance between a predetermined position and the object, a memory which stores position information expressing a mutual positional relationship of the predetermined position and the position of the image sensor, and a calculator which calculates a second distance between the position of the image sensor and the object based on the first distance and the position information. A display device displays a composite image which consists of a sensed image and a virtual image for an observer, wherein the composite image is created by comparing the second distance and distance information involved in the virtual image.

摘要： An optical device includes: a light source that emits a light beam; a deflector that deflects the light beam in a main-scanning direction; and a scanning/image-forming optical system that includes a scanning lens that causes the light beam deflected by the deflector to converge to a scanned surface to form an image on the scanned surface. The scanning lens has refractive index gradient. At least one surface of the scanning lens is a tilt-decentered surface that has a tilt angle, which depends on a position in the main-scanning direction, in a sub-scanning direction. The tilt angle is set so as to compensate for variation, which results from the refractive index gradient, in direction of the light beam in the sub-scanning direction.

摘要： Each of a plurality of pixels is formed with a group of a plurality of spots or a single spot. The barycentric position of each pixel is determined by the distribution of the spots or the position of the single spot. While the number of pixels on the exposure object is maintained in a first direction corresponding to the array direction of the light sources, an exposure feasible width on an exposure object can be adjusted in the first direction by setting the barycentric position at least in the first direction out of the first direction and a second direction that is the moving direction of the exposure object.
