Abstract
To suppress sudden changes in brightness due to a disturbance in a captured image, provided is a medical observation device, including: an acquisition section that acquires a sensing result of a brightness of an image of a subject in a living organism; and a control section that decides, according to a first interval in which the brightness sensing result indicates a value inside a certain range, a second interval in which to maintain an exposure of an imaging section at an exposure corresponding to a value included in the range.
Claims22
A surgical imaging system, comprising:
- a surgical imaging device configured to capture an image of a surgical site by radiating light onto the surgical site;
- and
- processing circuitry configured to
- acquire a sensing result of a brightness of the image of the surgical site during a first time interval,
- control, during the first time interval, an exposure of an imaging by the surgical imaging device based on the sensing result of the brightness of the image of the surgical site acquired during the first time interval, and
- control, during a second time interval after the first time interval, a maintaining of an exposure of an imaging by the surgical imaging device, at an exposure corresponding to a value included in a predetermined range, based on information other than a sensing result of a brightness of the image of the surgical site acquired during the second time interval.
A surgical imaging method, comprising:
- capturing, using a surgical imaging device, an image of a surgical site by radiating light onto the surgical site;
- acquiring, using processing circuitry, a sensing result of a brightness of the image of the surgical site during a first time interval;
- controlling, during the first time interval, an exposure of an imaging by the surgical imaging device based on the sensing result of the brightness of the image of the surgical site acquired during the first time interval;
- and
- controlling, using the processing circuitry and during a second time interval after the first time interval, a maintaining of the exposure of the imaging by the surgical imaging device at an exposure level corresponding to a value included in a predetermined range based on information other than a sensing result of a brightness of the image of the surgical site acquired during the second time interval.
A surgical imaging control device, comprising:
- processing circuitry configured to
- acquire a sensing result of a brightness of an image of a surgical site during a first time interval,
- control, during the first time interval, an exposure of an imaging by a surgical imaging device based on the sensing result of the brightness of the image of the surgical site acquired during the first tune interval, and
- control, during a second time interval after the first time interval, a maintaining of the exposure of the imaging by the surgical imaging device configured to capture the image of the surgical site by radiating light onto the surgical site, at an exposure level corresponding to a value included in a predetermined range based on information other than a sensing result of a brightness of the image of the surgical site acquired during the second time interval.
