Stereoscopic endoscope device having mechanism that changes an angle between optical axes of two imaging sensors

摘要

An appropriate stereoscopic image of a subject is readily acquired. Provided is a stereoscopic endoscope device including two image capture elements spaced apart from each other and disposed at a distal end of an insertion section to be inserted into a subject; an angle changing mechanism that changes a relative angle between optical axes of the image capture elements; a distance sensor that detects the distance from the image capture elements to the subject; and a controller that controls the angle changing mechanism on the basis of the distance detected by the distance sensor.

1. A stereoscopic endoscope device comprising:
two imaging sensors spaced apart from each other and disposed in an insertion section to be inserted into a subject; an angle changing mechanism that changes a relative angle between optical axes of the imaging sensors; a distance sensor that detects a distance from the imaging sensors to the subject; and a controller that controls the angle changing mechanism on the basis of the distance detected by the distance sensor, wherein the controller includes a memory that stores a map in which the distance and information indicating the relative angle are in correspondence with each other, and, on the basis of the map, controls the angle changing mechanism so that the relative angle indicated in the information corresponding to the distance detected by the distance sensor is achieved, the distance and the information indicating the relative angle that are in correspondence with each other in the map have a relationship such that the relative angle changes in a stepwise fashion relative to the distance, and the distance and the information indicating the relative angle that are in correspondence with each other in the map have a relationship such that the relative angle changes relative to different distances between when the distance changes in an increasing direction and when the distance changes in a decreasing direction.
