Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a control method for a mobile terminal and a mobile terminal.
Background
At present, mobile terminals are increasingly popularized, and in order to reduce unnecessary power consumption of the mobile terminals and improve endurance time, when a user uses the mobile terminal (for example, a mobile phone) to make a call in a face-near manner, the power consumption of the mobile phone is generally saved in a manner of turning off screen brightness.
In the prior art, the scheme adopted is mainly to judge whether an object (namely, an object) approaches to a screen by enabling a mobile phone to emit infrared rays. Specifically, the mobile phone can judge whether an object generates an event close to or far away from the screen according to an energy difference value between the transmitted infrared ray and the received infrared ray, so that the on and off of the screen lamp are realized. Namely, when the energy difference value is larger than a preset threshold value, it indicates that an object is close to the screen and needs to be turned off; and when the energy difference value is smaller than the preset threshold value, the fact that an object is far away from the screen is indicated, and the screen needs to be lightened.
However, in the prior art, the scheme of determining whether an object is close to or far away from the screen through infrared rays can be affected by the size and material of the light-transmitting hole for emitting infrared rays, so that the problems of determination errors and invalid object identification can be solved. Specifically, if a black object is present on the surface of the light-transmitting hole, and the reflection capability of the black object is weak, the energy value received by the infrared sensor is extremely low, so that the energy difference obtained by the infrared sensor is high and higher than a preset threshold value, and the screen is turned off. However, in reality, the screen is not a human tissue (for example, a human face or hair), which causes invalid judgment of the blocking object, that is, an event that the human tissue is close to or far from the mobile phone screen cannot be accurately and effectively identified, and the screen is turned on or off.
Therefore, the control scheme of the mobile terminal in the prior art generally has the problems that when the mobile terminal is detected to be in a call state, the recognition rate of human tissues close to a screen is low, and the screen-off control error rate of the mobile terminal is high.
Disclosure of Invention

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment
Referring to fig. 1, there is shown a flowchart of a control method of a mobile terminal according to an embodiment of the present invention,
before describing the flow of the embodiment of the present invention, first, it is necessary to describe a principle that the embodiment of the present invention solves the problems that in a control scheme of a mobile terminal in the prior art, when the mobile terminal is in a call state, the recognition rate of human tissues is low, and the accuracy of the screen-off control of the mobile terminal is low and the error rate is high. Therefore, the embodiment of the invention abandons the technical scheme of adopting an infrared sensor to detect whether human tissues are close to the screen in the prior art, and determines whether the object is the human tissues by analyzing the spectral information of the object based on the molecular layer, so that the accuracy of the judgment result is higher.
Specifically, the method may specifically include the following steps:
step 101, when detecting that the mobile terminal is in a call state, acquiring spectral information of an object shielding a screen of the mobile terminal;
the method comprises the steps that when the mobile terminal is in a call state, spectral information can be acquired for an object in front of a screen of the mobile terminal;
step 102, judging whether the object is human tissue or not according to the spectral information;
then, whether the object is human tissue (such as hair, skin, etc.) is determined according to the spectral information.
And 103, if yes, controlling the mobile terminal to be in a screen-off state.
If the user is actually human tissue, the user is indicated to hold the mobile phone to answer or make a call beside the ear.
Therefore, the embodiment of the invention judges whether the object is human tissue or not by acquiring the spectral information of the object shielding the mobile terminal, and the screen is turned off only when the object is human tissue, so that the problem that the screen is turned off by mistake because non-human tissue is close to the screen of the mobile terminal can be avoided, the recognition rate of the human tissue close to the screen is improved, the screen turning-off control accuracy of the mobile terminal is enhanced, and the invalid screen turning-off operation is avoided.
Second embodiment
Referring to fig. 2, a flowchart of a method for controlling a mobile terminal according to an embodiment of the present invention is shown, where the method may specifically include the following steps:
when the mobile terminal is detected to be in a call state, a molecular sensor arranged on the mobile terminal can be adopted to scan an object blocking a screen of the mobile terminal, so that spectral information of the object is acquired.
then, the ratio of each substance constituting the object in the tissue of the entire object, for example, the ratio of water, the ratio of protein, the ratio of lipid, the ratio of carbohydrate, the ratio of inorganic salt, and the like can be determined by analyzing the spectral information.
wherein, the approximate composition ratio of each component of human tissue is relatively stable, wherein, the water accounts for about 55 percent to 67 percent, the protein accounts for about 5 percent to 18 percent, the lipid accounts for about 10 percent to 15 percent, the carbohydrate accounts for about 1 percent to 2 percent, the inorganic salt accounts for about 3 percent to 4 percent, and the like.
Therefore, the proportion of each component constituting the object can be matched with the proportion of the corresponding component of the human tissue, and the matching degree can be obtained.
whether the human tissue is close to the screen or not can be judged according to the matching degree, for example, if the matching degree is greater than a preset threshold, it is determined that the object belongs to the human tissue, and if the matching degree is less than the preset threshold, it is determined that the object does not belong to the human tissue, that is, other substances close to the screen, such as tables, chairs, computers, water cups and the like, which do not belong to the human tissue.
If yes, go to step 205 to control the mobile terminal to be in a screen-off state.
If the object is judged to be the human body tissue, the screen lamp of the mobile terminal is controlled to be turned off even if the screen lamp is in the screen-off state.
If not, that is, the object is not found to be human tissue, step 206, controlling the mobile terminal to continue to be in a bright screen state.
By means of the technical scheme of the embodiment of the invention, the embodiment of the invention can determine the proportion of each component constituting the object according to the spectral information of the object, and match the proportion of each component with the proportion of each component of human tissues, so that the mobile terminal is controlled to be turned off when the matching is successful. The method and the device have the advantages that the types of the objects close to the screen are obtained through analysis by judging the material components of the objects, the problem that when the shielding objects are black objects such as black hair and black pockets, the identification of human tissues is inaccurate in the prior art due to the fact that an infrared detection technology is used is solved, and the method and the device can realize the operation of screen lightening and screen extinguishing more accurately directly according to the composition information of the materials.
