IMAGING SYSTEM, IMAGING METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2019/203193

Kind Code:

A1

Abstract:

An imaging system 1 is provided with an imaging device 100 and a control device 200 for causing pre-imaging and main imaging to be performed by the imaging device 100. The control device 200 has: an image generation unit 210 that generates a subject image on the basis of one or more captured images in each of the pre-imaging and the main imaging; an interface unit 206 that accepts user input for displaying the subject image and setting a region of interest; a region-setting unit 211 that sets the region of interest on the basis of the user input; an S/N ratio calculation unit 212 that calculates an S/N ratio on the basis of the set region of interest and a region of non-interest; and a total exposure time calculation unit 213 that calculates, on the basis of the S/N ratio calculated for the one or more captured images, a total exposure time by which a maximum S/N ratio or a preset reference S/N ratio is obtained. The control device 200 causes the main imaging to be performed by the imaging device 100 on the basis of the total exposure time.
