Abstract

Embodiments of this application provide a display method, an electronic device, and a storage medium. In this method, if the electronic device is in or enters a landscape side-standing state, a landscape/portrait direction of the electronic device is determined based on a recognized face direction, and when the landscape/portrait direction determined based on the face direction is a portrait direction, a screen display direction of the electronic device is set to portrait display.

First claim

1 . A display method, applied to an electronic device, and comprising:
obtaining, when the electronic device is in or enters a landscape side-standing state, a first landscape/portrait direction of the electronic device determined based on a face direction; and if the first landscape/portrait direction is a portrait direction, setting a screen display direction of the electronic device to portrait display.

2 . The method according to claim 1 , wherein the obtaining a first landscape/portrait direction of the electronic device determined based on a face direction comprises:
obtaining the face direction recognized based on image data collected by a front camera; and determining the first landscape/portrait direction based on an included angle α between the face direction and a natural direction of the electronic device, wherein the natural direction of the electronic device is a direction from a lower end of the electronic device to an upper end, and the upper end is an end at which the front camera and a rear camera are located.

3 . The method according to claim 2 , wherein the determining the first landscape/portrait direction based on an included angle between the face direction and a natural direction of the electronic device comprises:
when α∈(0°−β, 0°+β), the first landscape/portrait direction is a portrait direction at 0°; when α∈(90°−β, 90°+β), the first landscape/portrait direction is a landscape direction at 90°; when α∈(180°−β, 180°+β), the first landscape/portrait direction is a portrait direction at 180°; or when α∈(270°−β, 270°+β), the first landscape/portrait direction is a landscape direction at 270°, wherein β indicates a direction recognition range threshold, and β is greater than 0° and less than 45°.

4 . The method according to claim 3 , wherein the determining the first landscape/portrait direction based on an included angle between the face direction and a natural direction of the electronic device further comprises:
when α∈[β, 90°−β], α∈[90°+3, 180°−β], α∈[180°+β, 270°−β], or α∈[270°+β, 360°−β], a value of the first landscape/portrait direction indicates unknown.

5 . The method according to claim 3 , wherein an angular resolution at which a chip platform used by the electronic device performs face direction recognition is 30°, and β=30°.

6 . The method according to claim 2 , further comprising:
obtaining, when the electronic device is in or enters the landscape side-standing state, the image data collected by the front camera; and performing face direction recognition based on the image data.

7 . The method according to claim 6 , wherein the performing face direction recognition based on the image data comprises:
if only one face is recognized based on the image data, performing face direction recognition on the one face.

8 . The method according to claim 7 , further comprising:
if no face is recognized or a plurality of faces are recognized based on the image data, or there is an abnormality in recognition, determining that a value of the first landscape/portrait direction indicates unknown.

9 . The method according to claim 4 , further comprising:
if the value of the first landscape/portrait direction indicates unknown, maintaining a current screen display direction of the electronic device.

10 . The method according to claim 3 , further comprising:
if the first landscape/portrait direction is a landscape direction, maintaining a current screen display direction of the electronic device, wherein the landscape direction comprises the landscape direction at 90° and the landscape direction at 270°.

11 . The method according to claim 1 , further comprising:
when the electronic device exits the landscape side-standing state or is in a landscape non-side-standing state, obtaining a second landscape/portrait direction of the electronic device determined based on a gravity direction; and determining the screen display direction of the electronic device based on the second landscape/portrait direction.

12 . The method according to claim 6 , wherein the obtaining, when the electronic device is in or enters a landscape side-standing state, the image data collected by the front camera comprises:
when the electronic device is in or enters the landscape side-standing state, and there is a landscape/portrait auto-rotation requirement in a current scenario, obtaining the image data collected by the front camera.

13 . The method according to claim 6 , wherein the image data collected by the front camera is obtained in a real-time sampling manner.

14 . The method according to claim 13 , further comprising:
when the electronic device exits the landscape side-standing state, or when there is no landscape/portrait auto-rotation requirement in the current scenario, switching a sampling manner of obtaining the image data collected by the front camera from the real-time sampling manner to an interval sampling manner; and obtaining, in the interval sampling manner, the image data collected by the front camera, and performing face direction recognition based on the image data.

15 . The method according to claim 14 , wherein the switching a sampling manner of obtaining the image data collected by the front camera from the real-time sampling manner to an interval sampling manner comprises:
when it is determined that the sampling manner of obtaining the image data collected by the front camera needs to be switched from real-time sampling to interval sampling, obtaining delay duration; and when timing reaches the delay duration, switching the sampling manner of obtaining the image data collected by the front camera from the real-time sampling manner to the interval sampling manner.

16 . The method according to claim 14 , after the switching a sampling manner of obtaining the image data collected by the front camera from the real-time sampling manner to an interval sampling manner, further comprising:
when the electronic device enters or is in the landscape side-standing state and there is the landscape/portrait auto-rotation requirement in the current scenario, immediately switching the sampling manner of obtaining the image data collected by the front camera from the interval sampling manner to the real-time sampling manner.

17 . The method according to claim 1 , further comprising:
determining, on an application processor side, whether it is necessary to fuse the first landscape/portrait direction determined based on the face direction and a second landscape/portrait direction determined based on a gravity direction, to determine the screen display direction of the electronic device; or determining, on a coprocessor side, whether it is necessary to fuse the first landscape/portrait direction determined based on the face direction and a second landscape/portrait direction determined based on a gravity direction, to determine the screen display direction of the electronic device.

18 . The method according to claim 1 , wherein the electronic device comprises a landscape/portrait direction calculation module and a face direction calculation module; and
the obtaining, when the electronic device is in or enters a landscape side-standing state, a first landscape/portrait direction of the electronic device determined based on a face direction comprises: when the landscape/portrait direction calculation module determines that a posture of the electronic device is the landscape side-standing state, enabling the face direction calculation module, obtaining image data collected by a front camera, recognizing
