| Abstract(in English) | We present a new technique for capturing images where depth information on an object is invisibly and simultaneously embedded in its 2-D image when its image is taken with a camera. An object is illuminated by light that contains invisible patterns whose characteristics change depending on depth, therefore, the images of objects captured with a camera also invisibly contain their depth information. This invisible information on depth can be extracted by appropriate image processing from the captured image. We carried out experiments using periodical pattern whose spatial frequency changes depending on depth. We demonstrate that the depth map on a captured image can be produced by obtaining the frequency of the periodical pattern in the image using discreet Founer transform. |
