Abstract

An endoscopic device includes: an insertion portion configured to be inserted into a subject; an imaging unit configure to capture the subject image; a lens unit including a focus lens configured to adjust a focus by moving along an optical axis; a detection processor configured to perform detection processing of positioning a position of the focus lens at an in-focus position based on an image within the detection frame; a lens controller configured to position the focus lens at the in-focus position based on a processing result from the detection processor; a distal end detector configured to detect a distal end of a treatment tool in the captured image based on the captured image; and a detection frame setting unit configured to perform setting processing of setting a position of the detection frame in the captured image based on a position of the distal end of the treatment tool.

Claims14

Dependent claims

An endoscopic device comprising:

an insertion tube configured to be inserted into a subject to collect a subject image inside the subject from a distal end;
a sensor configured to capture the subject image;
a focus lens configured to adjust a focus when moved along an optical axis, the focus lens to image the subject image on the sensor;
and
circuitry configured to:
detect a distal end of a treatment tool included in the subject image in the captured image based on the captured image;
on condition that the distal end of the treatment tool is detected, automatically set a first position of a detection frame in the captured image around a position of the distal end of the treatment tool in the captured image, otherwise, on condition that the distal end of the treatment tool is not detected, set a second position of the detection frame, the first position and the second position being offset from one another, wherein the detection frame is a part of the captured image;
process an image within the detection frame;
determine an in-focus position of the focus lens for the subject image within the detection frame, based on the processed image within the detection frame, and
position the focus lens at the in-focus position while maintaining an observation field of the captured image.
