Patent number: 10527861Abstract: A color separation prism includes a filter, a first prism, a second prism, and a third prism. The first prism allows incidence of light transmitted through the filter, and the first reflective film reflects a first color component of the visible light and a part of the invisible light, among the light beams incident on the first prism. The second prism emits the light reflected by a second reflective film, and the second reflective film reflects the second color component of the visible light and a part of the invisible light, among the light beams incident on the second prism. The third prism emits the light transmitted through the second reflective film. The first reflective film and the second reflective film allocate the invisible light and the visible light emitted from each prism so as to obtain approximately uniform amount of the light.Type: GrantFiled: July 30, 2015Date of Patent: January 7, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Shuichi Horiguchi, Masahito Oka

Patent number: 8068286Abstract: A variable focal lens which does not require a reduction of a zoom factor and eliminates an origin sensor is provided. A microcomputer 15 functions as a focus adjustment section which controls a stepper motor 13 to move a focusing ring 5 for a focus adjustment. The microcomputer 15 causes the focusing ring 5 to move by a first moving distance in a first moving direction toward one of a FAR side and a NEAR side, and then to move the focusing ring 5 by a second moving distance in a second moving direction opposite to the first moving direction, and set the point where the focusing ring reaches after the movement in the second moving direction as a reference point for adjustment, and the microcomputer 15 causes the focusing ring 5 to move from the reference point for adjustment in the first moving direction within a range equal to or less than the second moving distance to carry out the focus adjustment.Type: GrantFiled: March 16, 2007Date of Patent: November 29, 2011Assignee: Panasonic CorporationInventors: Shuichi Horiguchi, Gentarou Irisawa, Yuichiro Mori, Masafumi Mizuno, Yasuji Nakamura

Publication number: 20090161069Abstract: An iris imaging lens (1A) comprises a biconvex spherical lens (2A), a biconcave spherical lens (3A), and a visible light cut filter (4A), and at least one surface of the visible light cut filter (4A) is formed as a curved surface. In this configuration, the visible light cut filter (4A) serves as a lens, so that aberration is corrected not only by the biconvex spherical lens (2A) and biconcave spherical lens (3A) but also by the visible light cut filter (4A). As a result, aberration can be reduced to improve the lens performance without increasing the number of imaging lenses, and the increase in the cost of manufacturing can be limited.Type: ApplicationFiled: September 27, 2006Publication date: June 25, 2009Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Shuichi Horiguchi, Gentaro Irisawa

Patent number: 7200248Abstract: An eye image pickup apparatus includes an image pickup unit, a guide mirror, a range sensor, and an infrared illuminating section. The image pickup unit includes an objective lens, an image pickup element such as a CCD, a shooting section and a light guide section as a basic configuration, and the image pickup unit shoots an image of an eye of a person. The guide mirror guides a subject to a shooting position. The range sensor measures the distance between the image pickup apparatus and the subject. The infrared illuminating section illuminates the subject. Rough guidance of the user is made using the guide mirror and fine alignment is made by using a guiding visible light obtained from the light guide section.Type: GrantFiled: October 30, 2002Date of Patent: April 3, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Shuichi Horiguchi
