Claim 16:
17. A medical observation method comprising:
generating three-dimensional information of a surgical field from a surgical field image obtained by imaging the surgical field;
setting at least one region-of-interest based on at least one the surgical field image captured at a predetermined timing;
estimating 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;
generating a magnified surgical field image in which the estimated region-of-interest is magnified at a predetermined magnification;
outputting at least the magnified surgical field image to a display; and
determining whether the region-of-interest has reached an edge of the surgical field image, or comes to a position to overlap a vignetting region of the surgical field image;
in response to determination that the region-of-interest has reached the edge of the surgical field image or overlaps the vignetting region of the surgical field image, perform one of the following processes,
generating 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,
generating 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
stopping generating of a magnified surgical field image.
