Document Type and Number:
WIPO Patent Application WO/2020/252738
Kind Code:
A1
Abstract:
A method for manually calibrating a 3D parameter of a naked-eye 3D display screen, and an electronic apparatus. The method comprises: acquiring an off-screen distance between the eyes and a 3D film, and displaying a 3D test image according to the off-screen distance (S1); adjusting, according to a received image rotation command, a display rotation angle of the 3D test image, continuing to adjust same until the 3D test image is displayed with no diagonal stripes, and storing the current display rotation angle (S2); and when the eyes observe that the 3D test image is vivid, using a camera to acquire relative location information of the eyes and a display screen, calculating, according to the relative location information, a lateral deviation of the 3D test image, and storing the lateral deviation (S3). After attaching a 3D film, a user only needs to observe the image in order to adjust the display rotation angle of the 3D test image and complete the parameter calibration. The method can be implemented easily, thereby improving user experience.
