Publication number: 20240017669Abstract: A display image is obtained by superimposing an image showing a vehicle on a captured image obtained by capturing an image on a rear side from the vehicle. For example, the image showing the vehicle is a computer graphics image. For example, a change is made in a superimposed positional relationship between the captured image and the image showing the vehicle in accordance with motion of a viewpoint of a driver. Since the display image is not only made from the captured image obtained by capturing an image on a rear side from the vehicle, but the display image is obtained by superimposing the image showing the vehicle on the captured image, it is possible to easily provide a sense of distance by motion parallax.Type: ApplicationFiled: September 29, 2023Publication date: January 18, 2024Applicant: Sony Group CorporationInventors: Koji NAGATA, Takashi SAITOH, Koji AOYAMA, Kazuki YOKOYAMA
