AI Technical Summary

Problems solved by technology

Since the proximity state is determined by comparing the proximity value with the threshold value, this will lead to an abnormal proximity state, which will cause the screen to flicker

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0022] figure 1 It is a flow chart of a method for preventing an abnormal proximity state provided by an embodiment of the present invention. This embodiment is applicable to preventing an abnormal proximity state judged based on the proximity value obtained by a proximity sensor. The method can be implemented by preventing an abnormal proximity state device, the device may be implemented by software and / or hardware, and the device may be configured in a mobile terminal such as a mobile phone. The method specifically includes...

Abstract

The invention discloses a method, device and mobile terminal for preventing an approaching state abnormity. The method comprises the steps that a time interval for changing between two adjacent object approaching states is acquired; when the time interval is smaller than a preset value, approaching values of continuous preset times obtained by an approaching sensor are acquired; according to the approaching values of the continuous preset times, an approaching threshold value used to judge an object approaching state is determined; and the object approaching state is determined according to the approaching threshold value and the latest approaching value among the approaching values of the continuous preset times, and the object approaching state takes the place of the last object approaching state in the changing of the two adjacent object approaching states. According to the invention, jumping changing of the approaching states is synthesized into the approaching threshold value, so that screen sparkling caused by the approaching state abnormity can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to proximity sensor technologies, and in particular to a method, device and mobile terminal for preventing abnormal proximity states. Background technique [0002] Proximity sensor is a general term for sensors that detect objects without touching them. A common application in mobile phones is to determine the proximity status according to the proximity value of the proximity sensor during the process of answering the phone, and automatically lock the screen according to the proximity status to avoid false triggers caused by touching the touch screen with the face. Turning off the backlight can effectively save energy and prolong the standby time. [0003] During the use of mobile terminals such as mobile phones, due to problems such as the aging of the proximity sensor and the stability of the power supply, the proximity value obtained by the proximity sensor will be probabilistically abnormal, for example,...
