Latest Nintendo patent involves projection that can correct itself to the user’s perspective

Several months ago, Nintendo filed a patent for a projection system / projector device / image capturing device and program. Today, it was finally made public.

Essentially, the patent involves a projection that can correct itself to the user’s perspective. Here’s the abstract:

“The present invention implements a projection system which appropriately corrects geometric distortion of a projected image even when an object to be projected has an arbitrary three-dimensional shape and a user’s point of view is not fixed. A projection unit (3) of a projector device 100 projects a first adjustment test image. A three-dimensional shape measurement unit (4) measures a three-dimensional shape of the object to be projected. An image capturing device (200) captures the first adjustment test image projected by the projection unit (3), and acquires a first adjustment captured image. A projected image adjustment unit (1) executes: (1) first adjustment processing for, on the basis of the first adjustment captured image acquired by the image capturing device (200), correcting the image such that geometric image distortion is reduced at an image capturing point at which the first adjustment captured image was captured; and (2) second adjustment processing for, on the basis of a state when the image adjusted by the first adjustment processing was projected by the projection unit (3), correcting the image such that geometric image distortion is reduced.”
