How does SONY achieve single-lens 3D?

The principle of the single-lens 3D camera currently officially announced by Sony is as shown in the figure. It still uses two CMOS image sensors to record the left and right images respectively, and then synthesizes them into 3D images. This technology was launched in 2009 It was announced that it is currently used in relatively high-end cameras.

However, current Cybershot digital cameras, Alpha SLRs, and NEX mirrorless cameras that can shoot 3D functions do not use this technology. ?It is a method called parallax 3D imaging principle,? Specifically, there is a layer of microlenses in front of the CMOS sensor. When light from different angles is projected onto the CMOS, it will be offset by the lens,? Then the images are recorded in alternate columns. That is to say, the images of odd-numbered and even-numbered columns are recorded respectively. There is a certain observation between these two images. Combining these two images can become a pseudo 3D photo.

The reason why To add a fake word, the 3D images captured by this method are actually not that good. If you want 3D to be as good as Avatar, you still need dual lenses.
