Claim 12:
13. A camera module, comprising: a lens group and an optical processing apparatus; and wherein:
the lens group is configured to focus an object to be captured, collect reflected light of the object to be captured and output the reflected light to the optical processing apparatus; and
wherein the optical processing apparatus is configured to receive an incident light output by the lens group and comprises:
a light splitting assembly, disposed on an optical path of an incident light and configured to receive the incident light and split the incident light into at least two lights with different waveband, a difference between optical path lengths of at least two optical paths waveband lights, respectively from an incident surface of the light splitting assembly where the incident light enters to surfaces of the light splitting assembly where the least two lights emit, being less than a set threshold; and
a light sensing assembly, disposed on optical paths of the at least two lights and configured to receive the at least two lights;
wherein the light splitting assembly comprises:
a light splitting element, disposed on the optical path of the incident light and configured to split the incident light into a first light with a first waveband, a second light with a second waveband and a third light with a third waveband;
wherein the light splitting element is a triangular prism and has the incident surface, a first surface and a second surface respectively corresponding to three side surfaces of the triangular prism, from which the third light with the third waveband, the first light with the first waveband and the second light with the second waveband emit respectively.
