The details will be described below separately.
The present embodiment will be described in terms of a switching device for antenna feed points, which may be specifically integrated in an electronic device, such as a mobile interconnection network device (e.g., a smart phone, a tablet computer) or other network-enabled electronic devices.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for switching an antenna feed point according to an embodiment of the present application, including the following steps:
step S101, when the electronic equipment is in a call state, acquiring an ear image of a user.
In an embodiment, the call state includes a voice call state, such as an incoming call or an outgoing call, where the call type may be a telephone voice call or a voice call of an instant messaging software, such as a QQ voice or a WeChat voice, and the present invention is not limited thereto.
In practical use, when the electronic device is in a call state, a call can be connected by holding the electronic device with a hand, or a call can be connected by using an auxiliary call tool, for example, a device such as a bluetooth headset, and when a user inconveniently holds the electronic device with a hand and places the electronic device at the ear to realize a call by using a normal call mode, the auxiliary call mode can be started to realize a call.
When the electronic equipment is in a call state, judging whether the electronic equipment is currently in a handheld state;
if yes, acquiring an ear image of the user.
The method for judging whether the electronic device is currently in a handheld state may be various, and may be implemented by arranging a handheld sensing component or a component such as a temperature sensor, an acceleration sensor, or a gyroscope.
For example, the handheld sensing element is disposed at a side of the electronic device, and a user will inevitably apply a force to the side of the electronic device when holding the electronic device, so that the positioning of the handheld sensing element at the side of the electronic device is beneficial to improving the accuracy of sensing whether the user holds the electronic device. When the electronic equipment is in a call, whether the hand-holding sensing assembly arranged on the side of the electronic equipment is triggered is judged, if not, the fact that the user cannot hold the electronic equipment at present and put the electronic equipment at the ear for the call is indicated, and if the hand-holding sensing assembly is triggered, the fact that the user is holding the electronic equipment for the call is indicated. In other embodiments, a temperature sensor may be disposed on the electronic device, and the temperature sensor disposed when the electronic device is held in the hand senses the temperature of the user, thereby confirming that the electronic device is held in the hand. In addition, the motion state of the electronic device can be obtained through an acceleration sensor or a gyroscope, and then the judgment of the handheld state is realized according to the motion state of the electronic device, which is not listed one by one.
In an embodiment, the ear image of the user may be obtained through a front-facing camera of the electronic device, specifically, when the electronic device is in a call state and the electronic device is confirmed to be in a handheld state, the front-facing camera is turned on and a current frame is obtained, and then the ear image is extracted from the current frame.
Step S102, determining the current holding state of the electronic equipment according to the ear image, wherein the holding state comprises a left-hand holding state and a right-hand holding state.
In an embodiment, due to the characteristic that two ears of a person are symmetrical to each other, after the ear image of the user is acquired, it can be determined that the ear image is a left ear or a right ear according to the contour of the ear, and then it is determined that the electronic device is currently in a left-hand holding state or a right-hand holding state.
In an embodiment, a face image of the user may also be obtained, and in a normal case, when the user holds the electronic device for a call, the front of the electronic device may be directed at the left ear or the right ear, so the face image may be a side face image of the user, then facial features on the side face image are obtained, and it is determined that the side face directed at the electronic device is the left face or the right face of the user according to the facial features, so as to determine that the current electronic device is in a left-hand holding state or a right-hand holding state. The accuracy of judging the current holding state can be improved by combining the ear image and the face image.
It should be noted that, in an embodiment, regardless of whether the ear image or the face image of the user is acquired, the original image may be further subjected to preprocessing after being acquired, and the preprocessing may include image enhancement, smoothing processing, noise reduction processing, and the like. For example, after the original ear or face image is obtained, information in the image may be selectively enhanced and suppressed to improve the visual appearance of the image, or the image may be converted to a form more suitable for machine processing to facilitate data extraction or recognition. For example, an image enhancement system may highlight the contours of an image with a high pass filter, thereby enabling a machine to measure the shape and perimeter of the contours. There are many methods for image enhancement, such as contrast stretching, logarithmic transformation, density layering, and histogram equalization, which can be used to change image grayscales and highlight details.

In an embodiment, the antenna of the electronic device includes at least two antenna feed points, as shown in fig. 2, and fig. 2 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure.

in step S201, when the electronic device is in a call state, a distance between the electronic device and a user is acquired.
In an embodiment, the call state includes a voice call state, such as an incoming call or an outgoing call, where the call type may be a telephone voice call or a voice call of an instant messaging software, such as a QQ voice or a WeChat voice, and the present invention is not limited thereto.
In this embodiment, it is considered that the image of the ear of the user can be obtained only when there is a certain distance between the electronic device and the ear of the user, and the integrity or the definition of the ear image is affected when the electronic device is too close to or too far away from the ear of the user, so that the distance between the electronic device and the user can be obtained, and the ear image is further obtained when the distance reaches a proper position. The distance between the user and the electronic device can be measured by a distance sensor on the electronic device, which can be an infrared sensor or an ultrasonic sensor, etc.
Step S202, determining whether the distance satisfies a preset distance range, if yes, executing step S202, and if not, ending the process.
The preset distance range can be set by a user according to needs and can also be automatically set by the electronic equipment, for example, the preset distance range can be 10cm-30cm, and in the distance range, a front camera of the electronic equipment can acquire clear and complete ear images. Meanwhile, if the distance between the electronic equipment and the user is detected to be within the preset distance range, the current handheld call state of the electronic equipment can be further determined.

In an embodiment, due to the characteristic that two ears of a person are symmetrical to each other, after the ear image of the user is acquired, it can be determined that the ear image is a left ear or a right ear according to the contour of the ear, and then it is determined that the electronic device is currently in a left-hand holding state or a right-hand holding state.
In step S205, a preset holding state corresponding to the preset ear image is obtained to determine the holding state as the current holding state of the electronic device.
The holding state comprises a left-hand holding state and a right-hand holding state. Specifically, the step of obtaining the preset holding state corresponding to the preset ear image may include: and when the preset ear image is a left ear image, determining that the corresponding preset holding state is a left hand holding state, and when the preset ear image is a right ear image, determining that the corresponding preset holding state is a right hand holding state.
Step S206, selecting a target feed point from at least two antenna feed points on the electronic equipment antenna according to the holding state.
Step S207, controlling the connection target feed point to enable the electronic device to complete receiving and transmitting the radio frequency signal.

It can be understood that, when the control switch 13 turns on the port2, the radiator 11 is electrically connected to the rf module 12 at the second feed point 112, and at this time, the first antenna may be used for transceiving low-frequency rf signals, and the second antenna may be used for transceiving medium-frequency and high-frequency rf signals.
