Title:
MEDICAL-USE OBSERVATION SYSTEM, MEDICAL-USE OBSERVATION DEVICE AND MEDICAL-USE OBSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/080209
Kind Code:
A1
Abstract:
A three-dimensional information generation unit (14) generates a three-dimensional map (D(X,Y,Z)) (three-dimensional information) of an operative field from operative-field images (K(x,y)) captured by an image capture device (42a). And an area-of-interest setting unit (20) (a setting unit) sets at least one area of interest in an operative-field image captured at a predetermined timing. On the basis of the three-dimensional map and information concerning the area of interest, a detection area estimation unit (22) (an estimation unit) estimates a relative position corresponding to the area of interest from among the operative-field images captured at different timings from the predetermined timing. And on the basis of the three-dimensional information of and the pixel values of an operative-field image corresponding to the relative position of the area of interest estimated by the estimation unit, a parameter control unit (26) (an adjustment unit) adjusts the image capture parameters of the image capture device and of a light-source device (60) which is peripheral equipment of the image capture device, thereby causing an operative-field image to be captured, and a display control unit (40) outputs the captured operative-field image.
