Publication number: 20240161381Abstract: A computer-executable method for generating a side-by-side three-dimensional (3D) image includes the steps of creating a 3D mesh and estimating depth information of the raw image. The method further includes the steps of updating the left mesh area and the right mesh area of the 3D mesh based on the estimated depth information of the raw image and projecting each of the mesh vertices of the left mesh area onto a coordinate system of the side-by-side 3D image based on a left eye position, and projecting each of the mesh vertices of the right mesh area onto the coordinate system of the side-by-side 3D image based on a right eye position. The method further obtains the side-by-side 3D image by coloring the left mesh area and the right mesh area projected onto the coordinate system of the side-by-side 3D image based on the raw image.Type: ApplicationFiled: November 16, 2022Publication date: May 16, 2024Inventors: Sergio CANTERO CLARES, Wen-Cheng HSU, Shih-Hao LIN, Chih-Haw TAN

Publication number: 20240121373Abstract: Disclosed are an image display method and a 3d display system. The method is adapted to the 3d display system including a 3d display device and includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3d image format. Whether the input image is a 3D format image complying with the 3D image format is determined through a stereo matching processing performed on the first image and the second image. An image interweaving process is enabled to be performed on the input image to generate an interweaving image in response to determining that the input image is the 3D format image complying with the 3D image format, and the interweaving image is displayed via the 3D display device.Type: ApplicationFiled: May 10, 2023Publication date: April 11, 2024Applicant: Acer IncorporatedInventors: Kai-Hsiang Lin, Hung-Chun Chou, Wen-Cheng Hsu, Shih-Hao Lin, Chih-Haw Tan

Publication number: 20240046608Abstract: A 3D format image detection method and an electronic apparatus using the same are provided. The 3D format image detection method includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3D image format. A 3D matching processing is performed on the first image and the second image to generate a disparity map of the first image and the second image. The matching number of a plurality of first pixels in the first image matched with a plurality of second pixels in the second image is calculated according to the disparity map. Whether the input image is a 3D format image conforming to the 3D image format is determined according to the matching number.Type: ApplicationFiled: December 2, 2022Publication date: February 8, 2024Applicant: Acer IncorporatedInventors: Kai-Hsiang Lin, Hung-Chun Chou, Wen-Cheng Hsu, Shih-Hao Lin, Chih-Haw Tan
