Abstract: A user wears a virtual reality mask (VR mask) (100) and then watches a virtual reality image. The VR mask (100) blocks light incident from the outside. When the user wears the VR mask (100), the user cannot discover an obstacle (500) positioned outside the VR mask (100). The user may collide with the obstacle (500) and may be injured by the obstacle (500). Accordingly, in order to prevent injury to the user who uses the VR mask (100), it is necessary to make the user recognize the obstacle (500) positioned outside the VR mask (100). In order to recognize an obstacle, a virtual reality image and the obstacle may be displayed together, or the amount of light incident from the outside may be adjusted.

Abstract: The present disclosure relates to an apparatus and a method for generating an image, which may generate a new viewpoint image using few-shot 2D images and is characterized by extracting and learning albedo representing intrinsic color information from the few-show 2D input images, intrinsically decomposing a color value synthesized in the form of patch from a new viewpoint using the few-shot 2D input images and extracting patch-wise albedo during learning, perform geometric alignment necessary for pixel correspondence between a new viewpoint image and a selected 2D input image using a depth value synthesized in the form of patch from the new viewpoint, and generating the new viewpoint image by calculating an albedo consistency loss between the patch-wise albedo.
