and step S31, acquiring raw data of the touch screen under the condition that the voice call is in the on state and the distance sensor is in the off state.
In this embodiment, the raw data of the touch screen is a signal obtained by processing an induction signal acquired by a certain induction terminal by a touch chip, such as sampling, analog-to-digital conversion, quadrature demodulation, and the like.
In one embodiment, the acquiring raw data of the touch screen in a case where the voice call is in an on state and the distance sensor is in an off state further includes:
under the condition that the request of the voice call is received, judging whether the touch screen is in a bright screen state or not;
and under the condition that the touch screen is in a bright screen state, controlling the distance sensor to be in a non-working state.
In this embodiment, in order to avoid that the touch screen of the mobile terminal is irradiated by the infrared lamp in the distance sensor for too long time, thereby causing failure and permanent bright spots of the touch screen, it is necessary to keep the distance sensor in a non-operating state when the touch screen is in a bright screen state.
In one embodiment, the acquiring raw data of the touch screen in a case where the voice call is in an on state and the distance sensor is in an off state further includes:
under the condition of receiving the request of the voice call, judging whether the voice call is in a connection state or not;
and under the condition that the voice call is in a connected state, switching the working mode of the touch screen into a high-sensitivity original data detection mode.
In this embodiment, when the touch screen is in the high-sensitivity raw data detection mode, when the user answers a voice call, the face of the person gradually approaches the touch screen, and at this time, the person acts as a conductor, and the raw data of the touch screen changes.
And step S32, judging whether the variation of the original data of the touch screen exceeds a first preset value.
In this embodiment, after the raw data of the touch screen is detected, it is necessary to determine whether the variation of the raw data of the touch screen exceeds a set range value. And subtracting the reference data from the original data of the touch screen to obtain the variable quantity of the original data.
In an embodiment, the determining whether the variation caused by the raw data of the touch screen exceeds a first preset value further includes:
and carrying out noise processing on the raw data of the touch screen according to the determined noise processing method of the raw data of the touch screen.
In this embodiment, noise may be present in the raw data, resulting in noise, such as common mode noise, being present in the raw data set. It is therefore desirable to denoise the raw data in the raw data set to eliminate or reduce the effect of noise on the raw data.
In one embodiment, the noise processing method according to the determined raw data performs noise processing on the raw data of the touch screen, and previously includes:
and determining a noise processing method of the raw data of the touch screen according to the variable quantity of the noise on the raw data of the touch screen.
In this embodiment, the variation caused by the noise to the raw data of the touch screen may be a variation caused by the noise to the amplitude of the raw data, that is, an amplitude variation caused by the noise to the raw data; or may be a variation caused by noise to the phase of the original data, i.e., a variation caused by noise to the phase of the original data; or may include both of the foregoing variations, and is not particularly limited herein.
In one embodiment, the noise processing method for determining raw data of the touch screen according to an amount of change caused by noise to the raw data of the touch screen includes:
determining the level of the noise according to the variable quantity of the noise on the original data of the touch screen and the corresponding relation between the variable quantity of the noise on the original data of the touch screen and the noise level;
and determining a noise processing method of the raw data of the touch screen from a plurality of noise processing methods according to the level of the noise and the corresponding relation between the noise level and the noise processing method.
In this embodiment, there are various noise processing methods, and if only one noise processing method is used to process the noise of the original data, an ideal noise cancellation effect may not be achieved, and even a side effect may be generated.
Therefore, in the present embodiment, through the pre-configured correspondence relationship between the variation caused by the noise to the raw data of the touch screen and the noise level and the correspondence relationship between the noise level and the noise processing method, after the variation caused by the noise to the raw data of the touch screen is determined, the corresponding noise processing method can be determined by searching the correspondence relationship.
As An example, it is assumed that the noise causes a variation of a (a1, a2.. An), a noise level of B (B1, B2.. Bn), and a noise processing method of C (C1, C2... Cn) to raw data of the touch screen. The corresponding relations among the three are (a1, B1, C1), (a2, B2, C2), (An, Bn, Cn). Assuming that the variation of the noise on the raw data of the touch screen is a2, the noise level is B2 and the noise processing method is C2.
The correspondence relationship (the correspondence relationship between the variation caused by the noise to the raw data of the touch panel and the noise level, and the correspondence relationship between the noise level and the noise processing method) may be obtained by performing a plurality of cancellation tests on different variations by using different noise processing methods.
In one embodiment, the method for processing noise to determine raw data of the touch screen according to an amount of change caused by noise to the raw data of the touch screen further includes:
and under the condition that the variation caused by the noise to the original data of the touch screen exceeds a preset threshold value, determining to perform noise elimination processing on the original data of the touch screen.
In this embodiment, when the amount of variation caused by noise to the raw data of the touch screen is greater than or equal to a preset threshold, it is determined that noise cancellation processing is performed on the raw data of the touch screen; otherwise, determining not to perform noise elimination processing on the raw data of the touch screen. By this embodiment, side effects caused by noise cancellation of the original values that do not require noise processing can be avoided.
And step S33, controlling the mobile terminal to turn off the screen under the condition that the variation of the original data of the touch screen exceeds a first preset value.
In this embodiment, when the variation of the raw data of the touch screen exceeds a set range value, the mobile terminal is controlled to turn off the screen. Therefore, on one hand, the screen is turned off when the voice call is connected, and on the other hand, the electric quantity of the mobile terminal is saved.
In one embodiment, in the case that the variation of the raw data of the touch screen exceeds a first preset value, the controlling the mobile terminal to turn off the screen further includes:
re-acquiring original data of the touch screen;
judging whether the variation of the newly acquired original data of the touch screen exceeds a second preset value or not;
and under the condition that the variation of the newly acquired original data of the touch screen exceeds a second preset value, controlling the distance sensor to be in a working state, so that the distance sensor controls the mobile terminal to be on.
