Problems solved by technology

[0004] However, the side-view imaging device disclosed in Japanese Patent Application Laid-Open No. 11-089793 has a problem that since only one image of the subject image is displayed on the screen of the image display device, the range that can be observed at one time depends on Angle of view as the transmission window of the objective optical system

Abstract

An endoscope system of the invention includes an elongated insertion portion; an image pickup portion provided with an objective optical system having an optical axis diagonal to a longitudinal axis direction of the insertion portion and that picks up an image of a subject present in a field of view of the objective optical system and can rotate around the longitudinal axis of the insertion portion; a rotation angle detection portion that detects a rotation angle of the image pickup portion; an image pickup control portion that can have images of a plurality of subjects picked up while the image pickup portion makes one rotation by controlling the image pickup portion on the basis of the rotation angle detected by the rotation angle detection portion; and a signal processing portion that carries out signal processing for having each image of the plurality of subjects displayed on one display portion.

Description

technical field [0001] The present invention relates to an endoscope system, and more particularly to an endoscope system capable of displaying images of a plurality of subjects on a single display unit. Background technique [0002] An endoscope system configured with an endoscope or the like has been widely used in medical fields, industrial fields, and the like. In addition, the endoscope system is used, for example, in the medical field to observe a body cavity or tissue of a living body as an affected part. Furthermore, as an imaging device based on the aforementioned endoscope system, for example, there is an imaging device proposed in JP-A-11-089793. [0003] The side-view imaging device of Japanese Patent Application Laid-Open No. 11-089793 is constituted to have: a head having an imaging system for forming an image of a subject incident from a light-transmitting window on the side of the front end and capturing the image; A head in which the optical axis of the ca...
