Patent number: 4867570Abstract: Apparatus and method for obtaining three-dimensional information about an object, includes a first optical system, a projection device, a second optical system, and an image sensor. A plurality of pattern beams are radiated onto the object through the first optical system. Optical images formed by the pattern beams on the object are received by the image sensor through the second optical system to detect the positions of the received optical images. The distances from the detected positions of the optical images to a plurality of positions on the object are measured, thereby obtaining three-dimensional information about the object.Type: GrantFiled: December 22, 1988Date of Patent: September 19, 1989Assignee: Canon Kabushiki KaishaInventors: Kanehiro Sorimachi, Shigeru Yamada, Yasurou Sakamoto

Patent number: 4106040Abstract: A camera of the type in which the shutter actuator is operated by means of an electromagnet or a permanent magnet associated with a solenoid has a film winding mechanism and a shutter tensioning mechanism operatively connected with each other through an improved interconnecting mechanism which includes a cam arrangement and a switching arrangement for the electromagnet or the solenoid. The cam arrangement is constructed as having complementary camming surfaces to facilitate the minimization of dimensions of the interconnecting mechanism. During the film winding or shutter tensioning operation, the electromagnet or the solenoid is rendered inoperative or operative respectively by the switching arrangement to thereby reduce the torque of a single operating member for the film winding and shutter tensioning mechanisms.Type: GrantFiled: June 28, 1977Date of Patent: August 8, 1978Assignee: Canon Kabushiki KaishaInventors: Fumio Ito, Tadashi Ito, Akio Sunouchi, Kanehiro Sorimachi
