摘要： A virtual viewpoint image generation method for generating a virtual viewpoint image that is an image of an object viewed from a virtual viewpoint based on plural images of the object taken by plural cameras. Projection planes having a multi-layered structure are set on the images of the object, corresponding to a projection point of a projection plane. Color information of each projection point is determined based on color information of corresponding points, for each of the projection points overlapping when viewed from a reference viewpoint in a space. A degree of probability that the object exists at a distance corresponding to a position of the projection point is determined based on a degree of correlation of the corresponding points.

摘要： A lens shutter mechanism for camera includes a shutter opening/closing lever which opens or closes a shutter blade or blades. The lever is pivotally mounted on a movable shaft which is fixedly mounted on a shutter close lever. At the same time as an electromagnet, which is used to maintain the shutter open, is deenergized, the shutter close lever is operated to cause the shutter opening/closing lever to close the shutter blade or blades.

摘要： A focal plane shutter comprises a first and a second blind, a take-up and a winding drum supporting the opposite ends of the first blind, a take-up and a winding drum supporting the opposite ends of the second blind, a first blind winding pinion and a second blind winding pinion having an operationally integral relationship with the first and the second blind winding drum, respectively, and a pair of shutter winding sector-shaped gears in meshing engagement with the first and the second blind winding pinion, respectively, and adapted to rotate in response to a shutter charging command. Each of the sector-shaped gears have a hiatus which is located opposite to the associated pinion to release the meshing engagement when no shutter winding operation takes place. The sector-shaped gears and the pinions are located relative to each other in a manner such that rotation of the first blind winding pinion precedes rotation of the second blind winding pinion when a shutter winding operation is to be commenced.

摘要： An electrical shutter circuit for a camera includes a photoelectric transducer element which is responsive to light from an object being photographed to determine a proper exposure period in accordance with the brightness thereof, thus automatically controlling the operation of a shutter assembly which opens or closes an exposure light path. In the open position of the shutter assembly, the photoelectric transducer element is irradiated with light of a fixed, relatively low intensity emitted by a luminescent element so that the electrical shutter circuit is automatically operated for the closing operation after a period of time determined by the light from the luminescent element even if the incident light from the object being photographed is extremely weak or completely absent.

摘要： An apparatus for reading information out of an optical record medium including a semiconductor laser diode for emitting a laser beam, a collimator lens, a beam splitter, an objective lens, converging lens and a photodetector. The laser beam emitted from the laser diode is made incident upon the optical record medium via the collimator lens, beam splitter and objective lens, and a light flux reflected by the optical record medium is made incident upon the photodetector via the objective lens, beam splitter and converging lens. The laser diode and collimator lens are arranged such that the laser beam is projected upon the optical record medium in a de-focused condition, while the objective lens is in-focused on the optical record medium.
