CPC: by providing first and second parallax images to an observer's left and right eyes

Full Title

Full titles differ between systems:

IPC:

Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images > by providing first and second parallax images to an observer’s left and right eyes

CPC:

Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images (in microscopes G02B21/22) > by providing first and second parallax images to an observer's left and right eyes

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2020.
