Medical imaging system and imaging device

A medical imaging system comprising:

• an imaging module provided in a medical imaging device, the imaging module including
• a branching optical system that branches light incident via an imaging lens in at least two directions and emits the light, and
• two or more light receiving regions of an image sensor configured to receive the light emitted from the branching optical system in the at least two directions, respectively, and perform imaging;
• and
• an image processing circuitry configured to perform image processing of generating an extended depth of field (EDoF) image with an extended depth of field by using images captured by the two or more light receiving elements,
• the two or more light receiving regions being arranged at positions having different optical distances from a principal point of the imaging lens by a shift amount ΔZ, and
• the shift amount ΔZ being calculated as ΔZ=2×DoF×M (1<M<2) by using a depth of focus DoF of the imaging lens set on a basis of a pixel pitch p of the two or more light receiving regions and an aperture value F of the imaging lens, and a correction term M.
