Display processing apparatus, system and method

A display processing apparatus configured to process linearly polarized light emitted out from a display device, comprising a polarization conversion unit configured to convert the linearly polarized light into circularly polarized light in different rotation directions according to different positions in a display image of the display device, wherein

• when a display signal corresponding to a first position in the display image is a display signal of a first image and a display signal corresponding to a second position is a display signal of a second image, the polarization conversion unit converts linearly polarized light, emitted out from the display device during display at the first position, into circularly polarized light in a first rotation direction, and converts linearly polarized light, emitted during display at the second position, into circularly polarized light in a second rotation direction.

A display processing method, comprising:

• acquiring display information of different positions in a display image of a display device;
• and
• converting linearly polarized light, emitted out from the display device during display at a first position, into circularly polarized light in a first rotation direction, and converting linearly polarized light, emitted during display at a second position, into circularly polarized light in a second rotation direction, when a display signal corresponding to the first position in the display image is a display signal of a first image and a display signal corresponding to the second position is a display signal of a second image.
