1. A medical imaging system, 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 the 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.
