Embodiment 1

[0038] figure 2 Shown is a schematic flowchart of a method for automatically switching display modes of a portable terminal according to an embodiment of the present invention. The portable terminal in this embodiment takes a mobile phone as an example, and specifically includes the following steps:

[0039] S201. Acquire a facial image of a user when a specified operation is performed. The specified operation is: an operation that can trigger the automatic switching function of the display mode. Specifically, it can be: start or exit the application program, or it can be an internal operation of the application program, such as the "page turning" option in the browser, the "Start Game" option, or "Play" action in a video player, etc. It can also be set by the user according to usage habits, whether a certain operation triggers the display mode automatic switching function. While the specified operation is being executed, the camera of the mobile phone is turned on to acqui...

Embodiment 2

[0054] Figure 7 Shown is a schematic flowchart of another method for automatically switching the display mode of a portable terminal according to an embodiment of the present invention. The portable terminal in this embodiment still takes a mobile phone as an example, and specifically includes the following steps:

[0055] S701-S702 are the same as those described in S201-S202.

[0056] S703. Determine the current display mode of the mobile phone. If the current display mode is horizontal, go to S704; if the current display mode is vertical, go to S706.

[0057] S704. Apply an image matching algorithm to compare the user's facial profile with the vertical standard facial profile. If the similarity is greater than the threshold, go to S705, otherwise go to S708. The threshold is stored in the portable terminal and is used to determine whether the two digital images match. If the similarity is greater than the threshold, the two images are considered to match. Generally, the t...

Abstract

The utility model discloses a method for automatically switching the display mode of a portable terminal and a device thereof. The method for automatically switching the display model of a portable terminal comprises the steps of: attaining a user facial image, processing the user facial image to attain a user facial profile, comparing the user facial profile with a preset standard facial profile, using the compared result to switch the display mode of the portable terminal. A portable terminal capable of automatically switching display modes comprises an image acquisition unit for attaining a user facial image, an image processing unit for processing the user facial image attained by the image acquisition unit to attain a user facial profile, a comparison unit for comparing the user facial profile attained by the image processing unit with a preset standard facial profile, and a switching unit for referring to the compared result of the comparison unit to switch display modes.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method and device for automatically switching display modes of a portable terminal. Background technique [0002] In recent years, portable terminals such as mobile phones and PDAs (personal digital assistants) have become necessary tools for many people's daily life. With the continuous expansion of portable terminal functions, functions such as surfing the Internet, watching videos, and playing games have become more and more widely used. ground use. Taking mobile phones as an example, most of the current mainstream models use vertical display mode, and the vertical screen display limits the use of these functions to a certain extent. For example, when playing videos, most videos are horizontal (that is, the aspect ratio is greater than 1. Typical video width and height such as 4:3, 16:9, etc.), the horizontal screen display mode can make more effective use of the s...
