Abstract
A medical imaging system includes a first imaging element that receives NIR light and outputs a first image signal, a second imaging element that receives normal light and outputs a second image signal, a third imaging element that receives at least normal light and outputs a third image signal, and a signal processing unit that performs depth-of-field extension processing to generate an extended-depth-of-field image using at least two of the first image signal, the second image signal, and the third image signal. The optical path length from a mount surface to the first imaging element is set to be longer than the optical path length from the mount surface to the second imaging element, and to be shorter than the optical path length from the mount surface to the third imaging element. The present technology can be applied to, e.g., a medical imaging system capable of capturing an EDOF image.
