Title:
MEDICAL OBSERVATION SYSTEM, MEDICAL OBSERVATION DEVICE AND MEDICAL OBSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/054566
Kind Code:
A1
Abstract:
In this invention, a three-dimensional information generation unit (14) generates an operative field three-dimensional map (D(X, Y, Z)) (three-dimensional information), from an operative field image (K(x, y)) imaged by an imaging device (42a). Then, a region of interest setting unit (20) (setting unit) sets at least one region of interest in an operative field image (K(x, y)) imaged at a predetermined timing. On the basis of the three-dimensional map (D(X, Y, Z)) and the position of the region of interest set by the region of interest setting unit (20), a region of interest estimation unit (22) (estimation unit) estimates from within an operative field image (K(x, y)) imaged at a different timing to the predetermined timing, the position where the region of interest is present. Then, a zoom processing unit (26) (magnified image generation unit) generates a magnified operative field image (L(x, y)) comprising the estimated region of interest magnified by a predetermined magnification factor, and a display control unit (40) outputs at least the magnified operative field image (L(x, y)).
