Abstract

In a method for adjusting a viewing angle of 3D images using an electronic device, the electronic device includes a distance sensor, a camera lens and a 3D display screen. The distance sensor senses a distance between a viewer and the 3D display screen, and the camera lens to capture a digital image of the viewer. The method calculates a viewing angle of the viewer according to the distance and a displacement between the viewer and the 3D display screen, and calculates an angle difference between the viewing angle of the viewer and a viewing angle range of the 3D display screen. The method further adjusts a viewing angle of a 3D image according to the angle difference, and displays the 3D image on the 3D display screen according to the viewing angle of the 3D image.

Dependent claims

An electronic device, comprising:

a distance sensor, a camera lens, and a 3D display screen;
a storage system, and at least one processor;
and
one or more programs stored in the storage system and executed by the at least one processor, the one or more programs comprising:
an initialization module that sets an imaging ratio of the camera lens, and initializes a center point of the 3D display screen;
an image detection module that controls the distance sensor to sense a distance between a viewer and the 3D display screen, controls the camera lens to capture a digital image of the viewer, and detects a center point of two eyes of the viewer from the digital image;
a viewing angle calculation module that calculates a first displacement between the center point of the 3D display screen and the center point of the two eyes, calculates a second displacement between the viewer and the 3D display screen according to the first displacement and the imaging ratio of the camera lens, and calculates a viewing angle of the viewer according to the distance and the second displacement;
and
a viewing angle adjustment module that determines whether the viewing angle of the viewer exceeds a viewing angle range of the 3D display screen, calculates an angle difference between the viewing angle of the viewer and the viewing angle range when the viewing angle of the viewer exceeds the viewing angle range, adjusts a viewing angle of a 3D image to be displayed on the 3D display screen according to the angle difference, and displays the 3D image on the 3D display screen according to the viewing angle of the 3D image.
