Endoscope device and method and computer-readable storage device for controlling bending of endoscope device
First Claim
1. An endoscope device comprising:
- an insertion portion comprising a distal end;
an image sensor arranged at the distal end of the insertion portion, wherein the image sensor is configured to generate an imaging signal based on a subject image of a subject formed on the image sensor;
a bending actuator configured to bend the distal end of the insertion portion so as to change an imaging visual field of the image sensor; and
one or more processors comprising hardware, wherein the one or more processors are configured to perform a control process comprising;
processing the imaging signal to generate image data of a display image of the subject to be displayed on a display;
setting a first measurement point and a second measurement point on the display image of the subject;
calculating a first subject distance from the first measurement point to a reference point of the image sensor, and a second subject distance from the second measurement point to the reference point of the image sensor;
calculating a difference value between the first subject distance and the second subject distance; and
controlling the bending actuator to bend the distal end of the insertion portion such that the difference value is decreased.

Abstract
An endoscope device having one or more processors configured to perform a control process including: processing an imaging signal to generate image data of a display image of a subject, wherein the image signal is generated by an image sensor, wherein the image sensor is arranged at a distal end of an insertion portion, and wherein a bending actuator is configured to bend the distal end; setting a first measurement point and a second measurement point on the display image; calculating a first subject distance from the first measurement point to a reference point of the image sensor, and a second subject distance from the second measurement point to the reference point; calculating a difference value between the first subject distance and the second subject distance; and controlling the bending actuator to bend the distal end of the insertion portion such that the difference value is decreased.

11. A method comprising:
-
controlling, by one or more processors comprising hardware, an image sensor, arranged at a distal end of an insertion portion of an endoscope device, to generate an imaging signal based on a subject image of a subject formed on the image sensor; and performing, by the one or more processors, a control process comprising; processing the imaging signal to generate image data of a display image of the subject to be displayed on a display, setting a first measurement point and a second measurement point on the display image of the subject; calculating a first subject distance from the first measurement point to a reference point of the image sensor, and a second subject distance from the second measurement point to the reference point of the image sensor; calculating a difference value between the first subject distance and the second subject distance; and controlling a bending actuator to bend the distal end of the insertion portion such that the difference value is decreased.
