Patent number: 10122975Abstract: An endoscope includes a four color separation prism having a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism which respectively separate light incident from an affected area into a blue, red and green color components, and an IR component, first, second, third and fourth color image sensors, and a signal output. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area. The first color image sensor is disposed opposite to the second color image sensor and the third color image sensor across an incident ray which is incident vertically to an object side incident surface of the first color separation prism.Type: GrantFiled: April 6, 2017Date of Patent: November 6, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yota Hashimoto, Haruyasu Katahira, Yuuichi Takenaga
