Medical imaging system, medical imaging device, and operation method

A medical imaging device comprising:

• 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, wherein
• an optical path length from the mount surface to the first imaging element is shorter than an optical path length from the mount surface to the second imaging element.

An operation method for a medical imaging system, the method comprising:

• receiving light obtained by splitting incident light incident from a mount surface and outputting a first image signal by a first imaging element;
• receiving light split separately from the light and outputting a second image signal by a second imaging element;
• and
• performing 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, wherein
• the medical imaging system is configured such that an optical path length from the mount surface to the first imaging element is shorter than an optical path length from the mount surface to the second imaging element.
