摘要： An apparatus for photographing a moving object has a velocity detector that measures a velocity of an object, at least one camera that has an image sensor and is located so as to capture the object, an operating processor that calculates a photograph point in accordance with resolution required for an object image, a camera controller that controls the camera on the basis of a detected velocity so as to photograph the object when the object passes the photograph point, and an image transmitting processor that transmits image data, obtained by the camera, outside. The operating processor calculates the photograph point by using an object-resolution conversion diagram. The object-resolution conversion diagram represents a correspondence relationship between an angle of view, a number of pixels, an object distance, and a resolution.

摘要： A surveying instrument is provided having a sighting telescope and a distance measuring device. The sighting telescope has a focusing lens group which is moveable to focus an object to be measured. The distance measuring device measures a distance between the object and the surveying instrument. A focusing operation of the sighting telescope is carried out to move the focusing lens group to a focal position of the object in accordance with the distance between the object and the surveying instrument measured by the distance measuring device.

摘要： A projection-type liquid-crystal display in which a Fresnel lens in placed on the exit side of the liquid crystal panel to focus the image toward a projection lens. Preferably, the Fresnel lens has a non-symmetric pattern so as to efficiently gather light propagating through the display panel at an oblique angle coinciding with a reorientation angle of the liquid crystal. Additional optics on the incident side of the panel, perhaps including another non-symmetric Fresnel lens, collimates the light at the oblique angle.
