Patent number: 9117396Abstract: When the video images to be played back are three-dimensional (3D) images each including a first parallax image and a second parallax image obtained when an object in a 3D space is viewed from different viewpoints, a video attribute determining unit determines whether or not the frame rate of the images is within a predetermined frame rate range at which a flicker is likely to occur. When the frame rate of the 3D images is within the predetermined frame rate range, a frame rate converter raises the frame rate of the 3D images until the frame rate exceeds the predetermined frame rate range.Type: GrantFiled: September 13, 2012Date of Patent: August 25, 2015Assignees: SONY CORPORATION, SONY COMPUTER ENTERTAINMENT INC.Inventor: Koichi Takenaka
