Endoscope system, non-transitory computer readable medium, and method
An endoscope system includes circuitry configured to monitor a characteristic of an endoscope including an imaging device and a scope coupled to the imaging device, wherein the characteristic is indicative of whether the scope is inserted in a living body or not, in the event that the characteristic satisfies a predetermined condition, control a focus of the endoscope system in a first manner and, in the event that the characteristic does not satisfy the predetermined condition, control the focus of the endoscope system in a second manner, different from the first manner.
1. An endoscope system, comprising:
circuitry configured to:
monitor a characteristic of an endoscope including an imaging device and a scope coupled to the imaging device, wherein the characteristic is indicative of whether the scope is inserted in a living body or not;
in the event that the characteristic satisfies a predetermined condition, control a focus of the endoscope system in a first manner; and
in the event that the characteristic does not satisfy the predetermined condition, control the focus of the endoscope system in a second manner, different from the first manner, wherein the first manner includes auto focusing the focus of the endoscope system.
2. The endoscope system according to claim 1 , wherein the second manner includes setting the focus of the endoscope system to a fixed focus position.
3. The endoscope system according to claim 2 , wherein the fixed focus position is set to a focus position just prior to the characteristic satisfying the predetermined condition.
4. The endoscope system according to claim 1 , wherein the characteristic is a characteristic of an image captured by an image sensor via the scope.
5. The endoscope system according to claim 4 , wherein the characteristic is a color of the image.
6. The endoscope system according to claim 4 , wherein the characteristic is a color of a peripheral portion of the image.
7. The endoscope system according to claim 4 , wherein the characteristic is a luminance of the image.
8. The endoscope system according to claim 4 , wherein the characteristic is a fluctuation of luminance in a peripheral portion of the image within a predetermined period of time.
9. The endoscope system according to claim 1 , wherein the characteristic is a position of an insertion tube of the endoscope system.
10. The endoscope system according to claim 1 , wherein the characteristic is an inclination of a camera head of the endoscope system.
11. The endoscope system according to claim 1 , wherein the characteristic is an acceleration of a camera head of the endoscope system.
12. The endoscope system according to claim 1 , wherein the characteristic is a shape of a distal end port in an image captured by an image sensor via the scope.
13. The endoscope system according to claim 1 , wherein the characteristic is a focus evaluation value of the endoscope system.
14. The endoscope system according to claim 1 , wherein the characteristic is a setting information from a support arm of the endoscope system.
15. The endoscope system according to claim 1 , wherein the circuitry is further configured to output to a display, in the event that the characteristic satisfies the predetermined condition, a first captured image obtained by the imaging device just prior to the characteristic satisfying the predetermined condition.
16. The endoscope system according to claim 15 , wherein the circuitry is further configured to stop output of the first captured image and output a real-time captured image to the display in the event that the characteristic does not satisfy the predetermined condition.
17. The endoscope system according to claim 1 , wherein, after the characteristic satisfies the predetermined condition and then stops satisfying the predetermined condition, the circuitry is to control the focus of the endoscope system in the second manner gradually.
18. A non-transitory computer readable medium having stored thereon a program that, when executed by a computer, causes the computer to execute processing, the processing comprising:
monitoring a characteristic of an insertion portion that is to be inserted in and removed from a living body, the insertion portion to be connected to an image sensor that generate an image in a medical imaging system;
comparing the characteristics to a predetermined condition;
in response to the characteristic satisfying the predetermined condition, controlling a focus of the medical imaging system in a first manner and outputting a first captured image obtained by the imaging sensor just prior to the characteristic satisfying the predetermined condition; and
in response to the characteristic not satisfying the predetermined condition, controlling the focus of the medical imaging system in a second manner, different from the first manner, stopping outputting of the first captured image, and outputting a real-time captured image.
19. A method, comprising:
monitoring a characteristic of an insertion portion that is to be inserted in and removed from a living body, the insertion portion to be connected to an image sensor that generates an image in a medical imaging system;
comparing the characteristics to a predetermined condition, wherein the predetermined characteristic is a fluctuation of luminance in a peripheral portion of the image within a predetermined period of time;
in response to the characteristic satisfying the predetermined condition, controlling a focus of the medical imaging system in a first manner; and
in response to the characteristic not satisfying the predetermined condition, controlling the focus of the medical imaging system in a second manner, different from the first manner.
20. The method according to claim 19 , wherein the first manner includes auto focusing the focus of the medical imaging system.
