Publication number: 20240223738Abstract: A viewpoint setting unit of an image data generation device sets a reference viewpoint on a basis of position and orientation information regarding a head-mounted display, and a reference image drawing unit generates a reference image in a field of view corresponding to the reference viewpoint. An additional data generation unit acquires color information regarding an occluded part not represented in the reference image from a different viewpoint as additional sampling data. A reprojection unit of the head-mounted display transforms the reference image into an image from a latest viewpoint and determines a pixel value of the hidden part using the additional sampling data.Type: ApplicationFiled: May 19, 2021Publication date: July 4, 2024Applicant: Sony Interactive Entertainment Inc.Inventors: Kazuyuki ARIMATSU, Masaaki HAMADA, Hiroyuki KAWAHARA

Patent number: 10733963Abstract: A luminance space conversion section of an information processing apparatus converts an image signal represented in a luminance space corresponding to an SDR into a signal represented in a luminance space corresponding to an HDR, and outputs the converted signal to a synthesis processing section that performs alpha blend processing on an HDR image. In an adjustment mode, a parameter adjustment section allows a display apparatus to display an adjustment image represented in the SDR and adjusts a parameter used for a conversion of the luminance space so that a change in a display image is made small before and after converting the luminance space. The parameter is stored in a conversion parameter storage section after the adjustment and is used when a luminance signal conversion section performs conversion processing.Type: GrantFiled: September 29, 2017Date of Patent: August 4, 2020Assignee: SONY INTERACTIVE ENTERTAINMENT INC.Inventors: Kenichiro Yokota, Sachiyo Aoki, Masaaki Hamada, Yute Lin

Patent number: 9002779Abstract: To provide an apparatus and method for efficiently displaying image content, which is sent and received between a server and a client, in a correct direction. An image content providing server stores, as property information, original angle information indicating correct directions of image content as metadata of the image content. The server generates content information including the original angle information and sends the generated content information to a client. This allows the client to understand the correct direction of the image content received from the server, and to obtain and display image data in the correct direction by performing rotation processing in the client device based on the obtained information or to request the server to perform the rotation processing.Type: GrantFiled: December 16, 2003Date of Patent: April 7, 2015Assignee: Sony CorporationInventors: Masaaki Hamada, Norifumi Kikkawa, Yoshiki Tanaka, Takehiko Morita
