Abstract
A medical observation apparatus includes: a camera configured to capture an observation object to output an imaging signal; a support configured to movably support the camera; and controller circuitry configured to control, when a normal observation mode with white light is switched to a special-light observation mode with special light, the support such that the camera is moved to a position so as to obtain a working distance that is set for the special-light observation mode and that is shorter than a working distance in the normal observation mode.

A medical observation apparatus comprising:
- a camera configured to capture an observation object to output an imaging signal and including a zoom lens configured to change a zoom magnification;
- a support configured to movably support the camera;
- and
- controller circuitry configured to
- control, when a normal observation mode with white light used to image the observation object is switched to a special-light observation mode with special light used to image the observation object, the support such that the camera is moved to a position so as to obtain a working distance between the camera and the observation object that is set for the special-light observation mode and that is shorter than a working distance between e camera and the observation object in the normal observation mode,
- calculate a zoom magnification to obtain a field of view identical to a field of view in the normal observation mode with regard to a working distance between the camera and the observation object corresponding to the special-light observation mode;
- and
- move the camera to a position to obtain the working distance between the camera and the observation object corresponding to the special-light observation mode and change a magnification of the zoom lens to the calculated zoom magnification.
A medical apparatus for controlling a camera including a zoom lens and a support configured to movably support the camera, comprising:
- controller circuitry configured to
- receive an imaging signal of an observation object from the camera;
- control, when a normal observation mode with white light used to image the observation object is switched to a special-light observation mode with special light used to image the observation object, the support such that the camera is moved to a position so as to obtain a working distance between the camera and the observation object that is set for the special-light observation mode and that is shorter than a working distance between the camera and the observation object in the normal observation mode,
- calculate a zoom magnification to obtain a field of view identical to a field of view in the normal observation mode with regard to a working distance between the camera and the observation object corresponding to the special-light observation mode;
- and
- move the camera to a position to obtain the working distance between the camera and the observation object corresponding to the special-light observation mode and change a magnification of the zoom lens to the calculated zoom magnification.
A medical observation method implemented by a computer to perform processes for controlling a camera including a zoom lens and a support configured to movably support the camera, the processes comprising:
- receiving an imaging signal of an observation object from the camera,
- controlling, when a normal observation mode with white light used to image the observation object is switched to a special-light observation mode with special light used to image the observation object, the support such that the camera is moved to a position so as to obtain a working distance between the camera and the observation object that is set for the special-light observation mode and that is shorter than a working distance between the camera and the observation object in the normal observation mode,
- calculating a zoom magnification to obtain a field of view identical to a field of view in the normal observation mode with regard to a working distance between the camera and the observation object corresponding to the special-light observation mode;
- and
- moving the camera to a position to obtain the working distance between the camera and the observation object corresponding to the special-light observation mode and change a magnification of the zoom lens to the calculated zoom magnification.
