Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be noted that the following examples are only illustrative of the present invention, and do not limit the scope of the present invention. Similarly, the following examples are only some but not all examples of the present invention, and all other examples obtained by those skilled in the art without any inventive work are within the scope of the present invention.
The terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Note that the camera of the Mobile terminal is usually connected to an external device through an MIPI (Mobile Industry Processor Interface). In live-action navigation, the current picture is captured and processed by means of camera assistance. However, the MIPI frequency or other combined frequency generated by the camera typically falls within the navigation band (Beidou/GPS/Glonass, 1550-. In the design of a mobile terminal, for example, a mobile phone, a receiving antenna of a navigator is usually located at the upper end of the mobile phone and is very close to a rear camera, and when the camera is turned on, the same frequency interference generated by the camera easily affects the navigation antenna. This will affect the accuracy and real-time performance of the navigator under live-action navigation, and will give users a very bad navigation experience.
The conventional measures generally include spraying EMI (Electromagnetic Interference) ink, wrapping copper foil with ground, and the like. That is, prevent the camera interference frequency from leaking or intensively flowing back, and lead the interference into the middle frame ground in time, so as not to radiate outward. However, this approach adds additional hardware cost, and does not necessarily provide sufficient shielding against interference, and for areas where EMI ink cannot be applied to the structure and the copper foil is wrapped, hardware shielding measures are ineffective.
Embodiments of the present application provide a computer-readable storage medium, a mobile terminal, and a navigation control method thereof, so as to solve the above technical problems, and refer to the following embodiments of the present application specifically:
referring to fig. 1, fig. 1 is a flowchart illustrating a navigation control method of a mobile terminal according to an embodiment of the present disclosure. As shown in fig. 1, the navigation control method of the present embodiment includes the following steps:
step S10: and receiving a live-action navigation instruction input by a user. The instruction can be received through a screen of the mobile terminal, or the instruction can be received through an entity key arranged on the mobile terminal.
In actual operation, when a navigation service is started, which is input by a user, is received, for example, when the user clicks a navigation icon on a touch screen of a mobile terminal, whether live-action navigation is required or not is automatically prompted to the user, and a selection request of the user is further received. If the selection request is that live-action navigation is needed, switching to a live-action navigation mode, and continuing to execute the step S11; if the selection request is that no live-action navigation is needed, the navigator is directly started without any switching.
Step S11: and simultaneously starting the camera and the navigator according to the instruction so as to obtain the current live-action image through the camera to assist the navigator. The camera can be a rear camera of the mobile terminal.
In this embodiment, the live-action image acquired by the camera may be transmitted to the navigator, and the navigator combines the live-action image acquired by the camera and the map data in the navigator to form live-action navigation. The camera can process the image and then transmit the image to the navigator after acquiring the live-action image.
Step S12: and changing the working parameters of the camera to reduce the frequency interference of the camera to the navigator.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a mobile terminal according to an embodiment of the present disclosure. Specifically, fig. 2 is a schematic structural diagram of a back surface (a surface opposite to the touch screen) of the mobile terminal. As shown in fig. 2, since the mobile terminal 10 is designed, the navigation antenna 11 of the navigator is generally located at the upper end portion of the mobile terminal 10. The upper end refers to an end of the mobile terminal farthest from the ground when the user uses the mobile terminal in a normal or conventional manner. And the camera 12 is also typically located at the upper end of the mobile terminal 10. Therefore, the navigation antenna 11 and the camera 12 are close to each other. In the case of turning on the camera 12 and the navigator at the same time, the co-channel interference generated by the camera 12 easily affects the navigation antenna 11. This will affect the accuracy and real-time performance of the navigator under live-action navigation, and will give users a very bad navigation experience.
Therefore, when the camera 12 and the navigator are simultaneously started, the working parameters of the camera 12 are changed to reduce the frequency interference of the camera to the navigator. The operating parameters may include a frequency parameter or a power parameter or a frequency parameter and a power parameter of the camera 12.
It should be noted that the camera in this embodiment adjusts and changes the working parameters only in the live-action navigation mode. In the normal shooting mode, i.e. non-live-action navigation, the camera still uses the preset shooting parameters. Specifically, two schemes are preset for the working parameters of the camera, one is the working parameters in the live-action navigation mode, and the other is the working parameters in the non-live-action navigation mode, namely the working parameters in the normal shooting mode. The step also comprises the step of reminding the user whether to change the working parameters of the camera, and after receiving the selection of the user to change the working parameters of the camera, selecting the working parameters preset by the camera in the live-action navigation mode to shoot.
It should be understood that the camera is only used as an auxiliary tool to assist the navigator in live-action navigation in the live-action navigation mode. The imaging quality of the camera is not the first one, and in this mode, it is not desirable to take a picture of the current real scene image, such as a road, to form a very high-definition image. User navigation is a primary requirement, so imaging users with low image quality are acceptable and not easily discovered. Therefore, in the live-action navigation mode, the user can be automatically prompted whether to reduce the image quality of the camera to improve the navigation precision, and when the user selects yes, the camera is switched to the working parameters of the navigation mode, so that the navigation antenna cannot be interfered on the basis of meeting the live-action requirement.
Therefore, in the embodiment, the frequency interference of the camera to the navigator is reduced by changing the working parameters of the camera, so that the navigator can accurately receive and transmit navigation information in the navigation frequency, and the accuracy and the real-time performance of the navigator are improved. In this embodiment, the mobile terminal includes a mobile phone, a palm computer, various wearable devices, and the like.
Referring to fig. 3, fig. 3 is a flowchart illustrating another navigation control method of a mobile terminal according to an embodiment of the present application. In the embodiment, the frequency interference on the navigator is reduced by changing the frequency parameter of the camera. Specifically, as shown in fig. 3, the navigation control method of the present embodiment includes the following steps:
step S30: and receiving a live-action navigation instruction input by a user. The instruction can be received through a touch screen of the mobile terminal, and the instruction can also be received through an entity key arranged on the mobile terminal. The specific steps are as described above, and are not described herein again.
Step S31: and simultaneously starting the camera and the navigator according to the instruction so as to obtain the current live-action image through the camera to assist the navigator. The camera can be a rear camera of the mobile terminal. The specific steps are as described above, and are not described herein again.
Step S32: and changing the frequency parameter of the camera to reduce the frequency interference of the camera to the navigator.
As described above, two frequency parameters may be preset in this step, one is a shooting frequency parameter when a camera is used for shooting alone, and the other is a navigation frequency parameter used in the navigation mode. The shooting frequency parameter can be a default frequency parameter of the camera. And in a non-navigation mode, namely selecting a default frequency parameter-shooting frequency parameter when the camera is used singly. And when the user needs to perform live-action navigation, changing the parameters of the camera into navigation frequency parameters, wherein the navigation frequency parameters of the camera are not equal to the frequency of the frequency band of the navigator.
Specifically, the nonlinearity of the camera head generates many frequency multiplication components for the used MIPI frequency, namely, the input is a single frequency F0But the output will be 2 times F03 times F04 times F05 times F0And the like. The frequency multiplication components are the main interference falling into the navigation frequency band (1550-0At 400MHz by 4 MHz 1600MHz, the high channel in the NAVIGATION band interferes with reception by GLONASS (GLOBAL NAVIGATION satellite system) NAVIGATION satellites. Generally, a camera fluctuates in a certain range of the MIPI frequency, that is, the camera can perform shooting operation in the fluctuating range. If the MIPI of the camera is set to 405MHz, the 3 and 4 frequency multiplication is 3F0＝1215MHz，4F01620MHz, which avoids the navigator navigation band (1550 + 1605 MHz). It should be understood that this frequency of 405MHz is not the MIPI frequency for the best imaging quality of the camera, but the imaging chosen as live-action navigation mode is satisfactory. Thus, the present embodiment can set the default frequency parameter of the camera, i.e. the shooting frequency parameter, to 400MHZ, and the navigation frequency parameter of the camera to 405 MHZ. The camera can carry out shooting work at the frequency of 400MHz and the frequency of 405 MHz. In a non-navigation mode, namely when the camera is used singly, the default frequency parameter of-400 MHZ is selected. And when the user needs to perform live-action navigation, the parameter of the camera is changed to 405 MHz.
That is to say, the present embodiment can avoid the operating frequency of the camera from the navigation frequency band of the navigator by increasing the operating frequency of the camera. It should be understood that in other embodiments, the operating frequency of the camera may also be changed according to the actual navigation frequency band, for example, the navigation frequency band of the navigator is avoided by reducing the operating frequency of the camera.
As mentioned above, in this embodiment, the navigation frequency band of the navigator is avoided by changing the frequency parameter of the camera, so as to solve the problem of co-channel interference of the camera to the navigation antenna of the navigator under live-action navigation. In addition, the embodiment does not need to increase hardware measures, and can save great cost.
Referring to fig. 4, fig. 4 is a flowchart illustrating a navigation control method of a mobile terminal according to another embodiment of the present application. In the embodiment, the frequency interference on the navigator is reduced by changing the power parameter of the camera. Specifically, as shown in fig. 4, the navigation control method of the present embodiment includes the following steps:
step S40: and receiving a live-action navigation instruction input by a user. The instruction can be received through a touch screen of the mobile terminal, and the instruction can also be received through an entity key arranged on the mobile terminal. The specific steps are as described above, and are not described herein again.
Step S41: and simultaneously starting the camera and the navigator according to the instruction so as to obtain the current live-action image through the camera to assist the navigator. The camera can be a rear camera of the mobile terminal. The specific steps are as described above, and are not described herein again.
Step S42: and reducing the power parameter of the camera so as to reduce the frequency interference of the camera to the navigator.
Similarly, as mentioned above, two power parameters may be preset in this step, one is a shooting power parameter when the camera is used alone for shooting, the shooting power parameter may be a power parameter defaulted by the camera, and the other is a navigation power parameter used in the navigation mode. And in a non-navigation mode, namely selecting a default power parameter-shooting power parameter when the camera is used singly. And when the user needs to perform live-action navigation, changing the parameter of the camera into a navigation power parameter, wherein the value of the navigation power parameter of the camera is smaller than the value of the default shooting power parameter, so that the influence on the frequency of the navigator can be reduced by means of reducing the radiation energy.
In this embodiment, the power parameter includes a voltage parameter and a current parameter. Therefore, the purpose of reducing the radiation energy can be achieved by reducing the voltage parameter or the current parameter of the camera or simultaneously reducing the voltage parameter and the current parameter. It should be understood that the reduction of the voltage parameter and the current parameter of the present embodiment can be understood as the reduction of the voltage parameter and the current parameter in the live-action navigation mode relative to the voltage parameter and the current parameter required when the camera is used alone.
In other embodiments, other parameters of the camera can be changed to achieve the purpose of reducing the radiation energy of the camera, so that the influence of the camera on the navigation frequency band of the navigator is reduced.
Referring to fig. 5, fig. 5 is a flowchart illustrating a navigation control method of a mobile terminal according to another embodiment of the present application. In the embodiment, the frequency interference on the navigator is reduced by changing the power parameter of the camera and reducing the power parameter of the camera. Specifically, as shown in fig. 5, the navigation control method of the present embodiment includes the following steps:
step S50: and receiving a live-action navigation instruction input by a user. The instruction can be received through a touch screen of the mobile terminal, and the instruction can also be received through an entity key arranged on the mobile terminal. The specific steps are as described above, and are not described herein again.
Step S51: and simultaneously starting the camera and the navigator according to the instruction so as to obtain the current live-action image through the camera to assist the navigator.
