The light source 100 is used to output illumination light to the observation region, wherein the illumination light includes white light and/or polarized light. In other words, the light source 100 can output both white light and polarized light, and can also output polarized light or white light alone. When the endoscope device is normally used, white light can be used as a light source for endoscopic imaging, however, in some special application scenes, for example, when blood, turbid water, tissue debris, fog and the like exist in an observation area, the polarized light is used as the light source for endoscopic imaging, and a clearer image can be obtained.
Referring to fig. 2, in an embodiment, the light source 100 includes: a white light source 101 and a white light-to-polarization conversion module 102.

The white light-to-polarization module 102 is configured to convert white light into polarized light and direct the polarized light to a viewing area. The white light source 101 in the present embodiment may be natural light of the external environment. Because the image data under the white light imaging can normally image the observation area, and the image data under the polarized light imaging can realize imaging in an underwater environment (blood, turbid water, tissue debris and fog), the light source in the endoscope device provided by the embodiment provides white light and polarized light, and the requirements of endoscopic imaging with various light sources are met.
