Embodiment Construction

[0048] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0049] Before explaining and describing the embodiments of the present disclosure in detail, the application scenarios of the embodiments of the present disclosure will be introduced first. At present, in order to protect the mobile terminal, the user usually puts a film on the mobile terminal, but sometimes the film may block the distance sensor, resulting in a black screen when the user uses t...

Abstract

The invention provides a sensing threshold calibration method and device of a distance sensor, and belongs to the technical field of terminals. The method comprises the following steps: when a distance sensing value is detected by the distance sensor, determining a sensing difference of the distance sensing value and a sensing threshold, wherein the sensing threshold is used for judging whether to carry out a screen turn-on operation or a screen turn-off operation on a screen according to the sensing threshold; when the sensing difference is greater than a preset difference threshold, detecting the light intensity in the current environment to obtain a light intensity sensing value; and when the light intensity sensing value is greater than a preset light intensity threshold, calibrating the sensing threshold. By adoption of the sensing threshold calibration method and device provided by the invention, under the action of the distance sensor and a light intensity sensor, when the distance sensor of a mobile terminal is shielded by a foreign matter, the sensing threshold is initiatively calibrated, thereby improving the calibration efficiency, avoiding inconvenience of user and improving the user viscosity.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a method and device for calibrating a sensing threshold of a distance sensor. Background technique [0002] With the development of technology, mobile terminals are becoming more and more popular, and users can perform operations such as communication and entertainment through the mobile terminals. Among them, a distance sensor is usually installed on the mobile terminal, and the distance sensor can detect the distance sensing value between the mobile terminal and the user's hand, face and other reflective surfaces, and compare the detected distance sensing value with the sensing threshold of the distance sensor , so that when the distance sensing value is greater than the sensing threshold, the screen-on operation is performed, and when the distance sensing value is smaller than the sensing threshold, the screen-off operation is performed, so as to prevent the occ...
