Abstract
The invention provides a device and a system for determining a state of an optical system for an endoscope. The device comprises: an input interface configured to receive image data acquired by means of the optical system; a computing device configured to implement at least one evaluation module configured to determine an entire optical flow of the obtained image data, to identify on this basis at least one image flow vector, and, if at least two different image flow vectors have been identified, to determine on this basis at least one state of the optical system; and an output interface which is configured to generate an output signal which comprises an item of information about the determined at least one state of the optical system.

A system for determining a state of an optical system of an endoscope, comprising:
- an input interface;
- a computing device;
- and
- an output interface;
- and
- wherein:
- the input interface receives image data acquired by the optical system;
- the computing device determines the number of different image flow vectors from the image data and, when the number of different image flow vectors is one, sets the state to an unimpaired state and, when the number of different image flow vectors is at least two, sets the state to an impaired state;
- and
- the computing device outputs indica of the state via the output interface.
A method, comprising:
- receiving image data acquired by an optical system;
- determining the number of different image flow vectors from the image data and, when the number of different image flow vectors is one, setting the state to an unimpaired state and, when the number of different image flow vectors is at least two, setting the state to an impaired state;
- and
- outputting indica of the state via the output interface.
An endoscopic system, comprising:
- an optical system to receive images of a surgical site of a patient and present the images to medical personnel;
- an input interface to receive the images and process the images into image data;
- a computing device to process the image data;
- and
- an output interface to output indicum of the image data;
- and
- wherein:
- the computing device determines the number of different image flow vectors from the image data and, when the number of different image flow vectors is one, sets the state to an unimpaired state and, when the number of different image flow vectors is at least two, sets the state to an impaired state;
- and
- the computing device causes the output device to output indica of the state.
