Abstract

The invention discloses a method for calibrating a threshold value, which comprises the steps of starting a motor used for controlling a rotary camera assembly when calibration conditions of the threshold value of a signal receiver are met, and turning on a signal transmitter on the rotary camera assembly; reading an intensity value of signals received by the signal receiver by a preset reading period; judging whether the intensity value of the signals received by the signal receiver reaches a preset threshold value or not; judging whether the intensity value of the signals of the current period equals to an intensity value of signals of a previous period or not when the intensity value of the signals received by the signal receiver reaches the preset threshold value; and regarding the intensity value of the signals of the current period as the threshold value of the signal receiver when the intensity value of the signals of the current period equals to the intensity value of the signals of the previous period. Correspondingly, the invention further discloses a device for calibrating the threshold value. By adopting the method and the device disclosed by the invention, the threshold value of the signal receiver can be calibrated in a periodic mode, the reset accuracy of the rotary camera assembly is improved, and thus the number of misoperation times is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for calibrating a threshold value. Background technique [0002] The distance sensor of a mobile terminal with a rotating camera assembly is usually arranged on its top front. When the distance sensor rotates with the rotating camera assembly at a certain angle, if a call request is received at this time, the mobile terminal will not turn off the screen when the user is talking. May cause misoperation. Therefore, in the prior art, a signal transmitter and a signal receiver are arranged on the mobile terminal, and the signal transmitter and the signal receiver face each other when the rotating camera assembly is reset, and the strength value of the received signal is compared with the preset Threshold (that is, threshold value) to reset the rotating camera assembly. But at present, the threshold value is a fixed value, which is generally set be...
