Abstract
The present disclosure relates to a medical imaging system, a medical imaging device, and an operation method that make it possible to capture a medical image in which an operative field can be better observed.The medical imaging system includes: a first imaging element that receives light through a color filter and outputs a first image signal; a second imaging element that receives light not through a color filter and outputs a second image signal; an optical splitting system that splits incident light incident from a mount surface into light to be incident on the first imaging element and light to be incident on the second imaging element; and a signal processing unit that performs depth-of-field extension processing to generate an extended-depth-of-field image obtained by extending a depth of field 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 set to be shorter than the optical path length from the mount surface to the second imaging element. The present technology can be applied to, e.g., a medical imaging system capable of capturing an EDOF image.
