Augmented reality systems

Abstract

Apparatuses and techniques relating to an augmented reality (AR) device are provided. The device for augmenting a real-world image includes a light source information generating unit that generates light source information for a real-world image captured by a real-world image capturing device based on the location, the time, and the date the real-world image was captured. The light source information includes information on the position of a real-world light source for the real-world image. The device further includes a shadow image registration unit that receives the light source information generated from the light source information generating unit. The shadow image registration unit generates a shadow image of a virtual object overlaid onto the real-world image based on the light source information generated from the light source information generating unit.

Dependencies are inferred from the claim text.
