Title:
INFORMATION PROCESSING DEVICE AND PHOTOGRAPHIC SUBJECT INFORMATION ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/215820
Kind Code:
A1
Abstract:
A focus point information acquisition unit of this information processing device uses a polarized image, which was photographed from the viewpoint of an imaging device 12a, to acquire an incidence plane 86a with regard to the viewpoint at a focus point a on a photographic subject 72. A viewpoint control unit determines movement directions of imaging devices so as to obtain a suitable angle with the incidence plane 86a, and presents the result to a user. If the viewpoint of an imaging device 12b after moving is determined to be appropriate, a photographed polarized image is used to acquire an incidence plane 86b at the focus point a, and the line of intersection thereof with the incidence plane 86a serves as a normal vector n of the focus point a.
