Title:
MEDICAL IMAGING SYSTEM, MEDICAL IMAGING DEVICE, AND OPERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/044898
Kind Code:
A1
Abstract:
The present disclosure relates to a medical imaging system, a medical imaging device, and an operation method capable of capturing a medical image with which an operative field can be more satisfactorily observed. The medical imaging system comprises: a first imaging element for receiving light through a color filter and outputting a first image signal; a second imaging element for receiving light not through the color filter and outputting a second image signal; a branch optical system for branching incident light entering from a mount surface into light entering the first imaging element and light entering the second imaging element; and a signal processing unit for performing depth-of-field enlarging processing for generating a depth-of-field enlarged image in which a depth of field is enlarged by using the first image signal and the second image signal. Then, the optical path length from the mount surface to the first imaging element is configured to be shorter than the optical path length from the mount surface to the second imaging element. This technology is applicable to, for example, a medical imaging system capable of capturing an EDOF image.
