Abstract

In a case where a plurality of imaging apparatuses is used for a surgery, the appearance is regulated between images captured by the respective imaging apparatuses.According to the present disclosure, a medical system is provided, the medical system including a plurality of surgical imaging apparatuses and a control unit to which each of the surgical imaging apparatuses is connected, the control unit including a signal processing unit that links images captured by the respective surgical imaging apparatuses. With this configuration, in a case where a plurality of imaging apparatuses is arranged for a surgery, it becomes possible to regulate the appearance between images captured by the respective imaging apparatuses.

First claim

The invention claimed is:

1. A medical system comprising:
a plurality of surgical imaging apparatuses each having a different angle of view, the plurality of the surgical imaging apparatuses being physically separate apparatuses respectively; and
processing circuitry, to which each of the surgical imaging apparatuses is coupled, configured to
determine whether the plurality of the surgical imaging apparatuses image a same subject or different subjects concurrently, and
link images captured by respective ones of the plurality of the surgical imaging apparatuses in response to determining that the plurality of the surgical imaging apparatuses image the same subject concurrently, and not link the images captured by the respective ones of the plurality of the surgical imaging apparatuses in response to determining that the plurality of the surgical imaging apparatuses image the different subjects concurrently, wherein

the processing circuitry is further configured to, in response to determining that the plurality of the surgical imaging apparatuses image the same subject concurrently, perform a process of adapting a shake amount between the images captured by the respective ones of the plurality of the surgical imaging apparatuses, by tracking a first image of the images with a shake in accordance with a second image of the images without a shake or with a shake less than the shake of the first image, and correcting the shake in the first image by removing a shake component in the first image in accordance with the second image, and
the first image is captured by a first surgical imaging apparatus of the plurality of the surgical imaging apparatuses having a first angle of view, and the second image is captured by a second surgical imaging apparatus of the plurality of the surgical imagine apparatuses having a second angle of view different from the first angle of view.

2. The medical system according to claim 1 , wherein the plurality of the surgical imaging apparatuses include at least two different types of surgical imaging apparatuses of an endoscope, an extracorporeal scope, a microscope, or a surgical field camera.

3. The medical system according to claim 1 , wherein the processing circuitry is configured to switch whether or not to perform the linking, according to occurrence of an adjustment trigger.

4. The medical system according to claim 1 , wherein
the processing circuitry is configured to perform a process for the linking according to occurrence of an adjustment trigger, and
the adjustment trigger occurs by a user operation.

5. The medical system according to claim 1 , wherein
the processing circuitry is configured to:
obtain information regarding a state of an operating surgeon who performs a surgery; and
perform a process for the linking based on the obtained information.

6. The medical system according to claim 1 , wherein
the processing circuitry is configured to:
obtain identification information for identifying the plurality of the surgical imaging apparatuses; and
perform a process for the linking based on the obtained identification information.

7. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting colors between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

8. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting brightness between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

9. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting contrast between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

10. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting resolution between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

11. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting noise between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

12. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting a depth of field between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

13. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting a depth between stereoscopic images captured by the respective ones of the plurality of the surgical imaging apparatuses.

14. The medical system according to claim 1 , wherein the processing circuitry is configured to perform a process of adapting an angle of view between the images captured by the respective ones of the plurality of the surgical imaging apparatuses.

15. The medical system according to claim 1 , wherein the processing circuitry is configured to link an image captured by one of the plurality of the surgical imaging apparatuses with an image captured by another one of the plurality of the surgical imaging apparatuses as a reference.

16. The medical system according to claim 1 , wherein the processing circuitry is configured to link images captured by the plurality of the surgical imaging apparatuses with an arbitrary desired image as a reference.

17. A control unit comprising:
processing circuitry, to which each of a plurality of surgical imaging apparatuses is coupled, configured to
determine whether the plurality of the surgical imaging apparatuses image a same subject or different subjects concurrently,
link images captured by respective ones of the plurality of the surgical imaging apparatuses in response to determining that the plurality of the surgical imaging apparatuses image the same subject concurrently, and not link the images captured by the respective ones of the plurality of the surgical imaging apparatuses in response to determining that the plurality of the surgical imaging apparatuses image the different subjects concurrently, wherein

each of the plurality of the surgical imaging apparatuses has a different angle of view, the plurality of the surgical imaging apparatuses being physically separate apparatuses respectively,
the processing circuitry is further configured to, in response to determining that the plurality of the surgical imaging apparatuses image the same subject concurrently, perform a process of adapting a shake amount between the images captured by the respective ones of the plurality of the surgical imaging apparatuses, by tracking a first image of the images with a shake in accordance with a second image of the images without a shake or with a shake less than the shake of the first image, and correcting the shake in the first image by removing a shake component in the first image in accordance with the second image, and
the first image is captured by a first surgical imaging apparatus of the plurality of the surgical imaging apparatuses having a first angle of view, and the second image is captured by a second surgical imaging apparatus of the plurality of the surgical imaging apparatuses having a second angle of view different from the first angle of view.
