Classification: CPC A  G | IPC A

Claim 0:
1. A medical observation system comprising:
an imaging device that images a surgical field and obtains a surgical field image; and
circuitry configured to:
generate three-dimensional information of the surgical field from the surgical field image captured by the imaging device;
set at least one region-of-interest based on at least one of the surgical field image captured at a predetermined timing by the imaging device;
estimate an existence position of the region-of-interest from within a surgical field image captured at a timing different from the predetermined timing based on the three-dimensional information and the position of the region-of-interest set;
generate a magnified surgical field image in which the estimated region-of-interest is magnified at a predetermined magnification; and
output at least the magnified surgical field image to a display,

wherein, in a case where the region-of-interest has reached an edge of the surgical field image or overlaps a vignetting region of the surgical field image, the circuitry is to:
generate a magnified surgical field image that stores a predetermined pixel value in a region beyond the edge and the region overlapping the vignetting region in the region-of-interest,
generate a magnified surgical field image in which an edge of the magnified surgical field image is aligned with an edge of the surgical field image, or
stop generation of a magnified surgical field image.
