Embodiment 1
[0032] This embodiment will be described from the perspective of a calibration device for a proximity sensor. Specifically, the calibration device for a proximity sensor may be integrated into a terminal, and the terminal may be a smart phone, a tablet computer, or other devices.
[0033] A calibration method for a proximity sensor, comprising: acquiring a first proximity value generated by the proximity sensor based on a transmission parameter of a measurement signal, and comparing the first proximity value with a preset threshold to obtain a comparison result; adjusting the transmission parameter according to the comparison result , to obtain the adjusted emission parameters; determine whether the adjusted emission parameters meet the preset conditions; if so, correct the calibration parameters of the proximity sensor according to the adjusted emission parameters.
[0034] Such as figure 1 As shown, the calibration method of the proximity sensor, the specific process can be ...
Embodiment 2
[0089] According to the method described in Embodiment 1, an example will be given below for further detailed description.
[0090] In this embodiment, the calibration device for the proximity sensor will be specifically integrated in the mobile terminal and the proximity sensor is an infrared proximity sensor as an example for detailed description.
[0091] Such as figure 2 As shown, a calibration method of a proximity sensor, the specific process can be as follows:
[0092] 201. The mobile terminal judges whether the proximity sensor is in a blocked state; if yes, end the process; if not, execute step 202.
[0093] Specifically, in order to ensure the accuracy of the calibration, it is necessary to ensure that the current proximity sensor is not blocked during the calibration process. There are many ways to judge whether the proximity sensor is in the blocking state. For example, whether the proximity sensor is in the blocking state can be determined according to whether ...
Embodiment 3
[0116] In order to better implement the above method, an embodiment of the present invention also provides a proximity sensor calibration device. The proximity sensor calibration device can be integrated in a terminal, and the terminal can specifically include devices such as mobile phones, tablet computers, and notebook computers. Such as image 3 As shown, the calibration device of the proximity sensor may include: a comparison module 301, an adjustment module 302, a first judgment module 303 and a correction module 304, as follows:
[0117] A comparison module 301, configured to acquire a first proximity value generated by the proximity sensor based on the emission parameters of the measurement signal, and compare the first proximity value with a preset threshold to obtain a comparison result;
[0118] An adjustment module 302, configured to adjust the transmission parameters according to the comparison result, so as to obtain the adjusted transmission parameters;
