Because we’re a long ways away from all smartphones coming equipped with the requisite two cameras needed to shoot 3D, the only workaround to bring the video technology to any device would obviously involve an add-on or post-production technique or both.
That’s precisely what Fujitsu is developing: an accessory that uses mirrors to transmit two different images to the sensor of a single camera. The resulting video is then uploaded to Fujitsu for additional processing and then sent back to the device owner. Because the add-on only uses 25% of the camera’s sensor, 3D images will only be a quarter of the quality of a 2D image. It’s not ideal, but it's a start.
Currently, a release date for the add-on is still up in the air.
