Patent number: 11910095Abstract: In an information processing apparatus, a captured image acquiring section acquires data of an image captured of a reference object while part of incident light applied thereto is being blocked. An incident light information acquiring section acquires, according to a predetermined model equation, a brightness distribution of partial incident light in each of light-blocked states on the basis of the image of the reference object, and acquires a brightness distribution of overall incident light by calculating brightness distributions of partial incident light. A target information acquiring section acquires the shape and material of a target by using the brightness distribution of overall incident light.Type: GrantFiled: November 21, 2019Date of Patent: February 20, 2024Assignee: Sony Interactive Entertainment Inc.Inventors: Takayuki Ishida, Shinya Wada

Patent number: 11108966Abstract: A point-of-interest information acquisition section of an information processing apparatus acquires, by using a polarization image captured from a viewpoint of an imaging apparatus, an incident plane relative to the viewpoint at a point of interest ‘a’ on a subject.

When the post-movement viewpoint of an imaging apparatus is determined to be appropriate, an incident plane at the point of interest ‘a’ is acquired by using the captured polarization image, and a line of intersection with the incident plane is assumed to be a normal vector n of the point of interest ‘a.Type: GrantFiled: May 8, 2018Date of Patent: August 31, 2021Assignee: Sony Interactive Entertainment Inc.Inventors: Takayuki Ishida, Hiroyuki Segawa, Shinya Wada
