Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 17:
18. A non-transitory computer-readable medium storing instructions that, when executed by a processor of a projection device, cause the projection device to perform a set of operations comprising:
controlling a first light source to emit a first-eye light, wherein the first-eye light includes a first set of wavelengths;
controlling a second light source to emit a second-eye light, wherein the second-eye light includes a second set of wavelengths;
controlling a first projector to receive a first input light, the first projector including first projection optics; and
controlling an optical switch to switch between a first mode and a second mode,
wherein the optical switch, in the first mode, combines the first-eye light and the second-eye light into a combined light and directs the combined light to the first projection optics as the first input light,
wherein the optical switch includes a reflective element and a first filter, and
wherein controlling the optical switch to switch to the first mode comprises:
controlling the reflective element to move the first filter to a first position, so as to allow the first-eye light and the second-eye light to pass to the first projection optics as the combined light.
