[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first sensor may be referred to as a second sensor, and similarly, a second sensor may be referred to as a first sensor. Both the first sensor and the second sensor are sensors, but they are not the same sensor.

[0041] Due to the continuous upgrading of camera technology, the size of image sensors is getting larger and larger, the number of camera lenses is also gradually increasing and the weight is increasing. The greater the thrust required by the camera's autofocus motor, the greater the current required, which makes the power consumption of the entire camera device larger and larger, and the heating during use is getting more and more serious. During the use of the camera, due to the internal heating, a large temperature difference is generated between the inside and outside of the camera lens, and the water vapor inside the camera device will condense on the inner surface of the camera lens to form water mist. The water mist formed on the inner surface of the camera lens cannot be removed by wiping. You can only wait for the temperature of the inside and outside of the camera lens to reach the same level, or turn off the camera device to remove it. At the same time, it will also have an adverse effect on the clarity of the photos taken.

[0042] In addition, when the camera is moved from a lower temperature environment to a higher temperature environment, the water vapor in the higher temperature environment will condense into water mist when it meets the camera at a lower temperature, causing water mist to form on the outer surface of the camera lens, which requires manual wiping and will also affect the clarity of the photos taken.

[0043] In view of the problem that water mist is easily generated on the inner and outer sides of the camera lens in the above scenario, an embodiment of the present application provides a method for preventing water mist from forming on the camera lens, which can prevent water mist from forming on the camera lens.

[0044] The camera lens anti-fogging method provided in the embodiment of the present application can be applied to Figure 1 In the electronic device shown. The electronic device includes a camera device, which includes a camera lens 102, and a first sensor 104 on the first side of the camera lens 102 and a second sensor 106 on the second side, wherein the first side surface and the second side surface of the camera lens 102 are covered with a heating film (not shown in the figure). The electronic device obtains the first temperature collected by the first sensor 104 and the second temperature collected by the second sensor 106, and determines the temperature difference between the first side and the second side of the camera lens according to the first temperature and the second temperature. When the temperature difference is greater than the preset temperature difference, the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is heated. The electronic device can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, cameras, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc.

[0045] In one embodiment, Figure 2 As shown, a method for preventing camera lenses from fogging is provided, and the method is applied to Figure 1 Taking the electronic device in as an example, the method includes the following steps 202 to 206.

[0046] Step 202: Acquire a first temperature collected by a first sensor and a second temperature collected by a second sensor.

[0047] In this embodiment, the first sensor and the second sensor may be temperature sensors of the same model and the same parameters, for example, they may be thermistors; the first sensor and the second sensor are respectively located on both sides of the camera lens, wherein the first sensor and the second sensor may directly contact the camera lens, or may be at a certain distance from the camera lens, for example, the first sensor and the second sensor are respectively located on both sides at the same distance from the camera lens. The first sensor and the second sensor may be one or more.

[0048] The first sensor is used to collect a first temperature corresponding to the first side of the camera lens, and the second sensor is used to collect a second temperature corresponding to the second side of the camera lens. Optionally, the first sensor can be used to collect a first temperature of the first side surface of the camera lens, and the second sensor can be used to collect a second temperature of the second side surface of the camera lens. Optionally, the first sensor can be used to collect a first temperature at a preset distance from the first side surface of the camera lens, and the second sensor can be used to collect a second temperature at a preset distance from the second side surface of the camera lens.

[0049] Optionally, the first sensor collects the first temperature at the same frequency as the second sensor collects the second temperature, and they are kept synchronous. That is, when the first sensor collects the first temperature, the second sensor also collects the second temperature, and the collection frequencies are the same. For example, when the camera device is started, the first sensor and the second sensor start working at the same time, the first sensor collects the first temperature while the second sensor collects the second temperature, and then transmits the first temperature and the second temperature to the processor of the electronic device.

[0050] Step 204: Determine a temperature difference between a first side and a second side of the camera lens according to the first temperature and the second temperature.

[0051] The electronic device can determine the temperature difference between the first side and the second side of the camera lens according to the first temperature and the second temperature. Optionally, the absolute value of the difference between the first temperature and the second temperature is used as the temperature difference between the first side and the second side of the camera lens.

[0052] Optionally, when there are multiple first temperatures and multiple second temperatures, the average of the multiple first temperatures can be used as the first target temperature, the average of the multiple second temperatures can be used as the second target temperature, and then the difference between the first target temperature and the second target temperature can be used as the temperature difference between the first side and the second side of the camera lens.

[0053] It can be understood that data processing of the difference between the first temperature and the second temperature to obtain the temperature difference between the first side and the second side of the camera lens should be included in the protection scope of the embodiments of the present application.

[0054] Step 206: When the temperature difference is greater than the preset temperature difference, the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature is heated.

[0055] When the temperature difference is greater than the preset temperature difference, the electronic device heats the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature. The preset temperature difference can be set according to the specific application environment, and the preset temperature difference in different environments may be different. For example, the electronic device selects the preset temperature difference corresponding to the application environment type by identifying the application environment type. The preset temperature difference can also be a fixed value, for example, the preset temperature difference is 3°C (Celsius). It can be understood that when the temperature difference between the first side and the second side of the camera lens is greater than the preset temperature difference, it is determined that the current application environment will cause the camera lens to generate water mist, then the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is heated to prevent the generation of water mist.

[0056] Optionally, when a first temperature corresponding to the first side of the camera lens is higher than a preset temperature difference of a second temperature corresponding to the second side, it is determined that the current application environment will cause water mist to be generated on the first side surface of the camera lens, and the electronic device heats the heating film on the first side surface of the camera lens; when a second temperature corresponding to the second side of the camera lens is higher than a preset temperature difference of the first temperature corresponding to the first side, it is determined that the current application environment will cause water mist to be generated on the second side surface of the camera lens, and the electronic device heats the heating film on the second side surface of the camera lens.

[0057] Optionally, when the temperature difference is greater than a preset temperature difference, the corresponding electric heating parameters can be determined according to the temperature difference, and then the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is electrically heated according to the electric heating parameters. The electric heating parameters can be parameters such as heating power, heating current, and heating voltage. In addition, the electric heating parameters corresponding to the first side and the second side can be the same or different, for example, Figure 3 As shown, when the first temperature corresponding to the first side of the camera lens is higher than the preset temperature difference of the second temperature corresponding to the second side, the first electric heating parameter is determined according to the temperature difference between the first side and the second side, and the heating film on the first side surface is heated according to the first electric heating parameter; when the second temperature corresponding to the second side of the camera lens is higher than the preset temperature difference of the first temperature corresponding to the first side, the second electric heating parameter is determined according to the temperature difference between the first side and the second side, and the heating film on the second side surface is heated according to the second electric heating parameter.

[0058] In the above-mentioned method for preventing fogging of camera lenses, by obtaining the first temperature collected by the first sensor and the second temperature collected by the second sensor, the temperature difference between the first side and the second side of the camera lens is determined according to the first temperature and the second temperature. When the temperature difference is greater than the preset temperature difference, the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is heated. When there is a temperature difference between the inner and outer sides of the camera lens, the surface of the camera lens with a higher temperature is prevented from condensing into water mist when it is cold, thereby avoiding the camera lens from fogging and affecting the clarity of the captured image.

[0059] In one embodiment, heating the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature includes: determining a first current according to the temperature difference, and electrically heating the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature according to the first current.

[0060] Optionally, the corresponding relationship between the temperature difference and the first current can be obtained through preliminary experiments, and the corresponding relationship between the temperature difference and the first current can be stored in an electronic device or in a database. When the temperature difference is greater than a preset temperature difference, the corresponding first current is determined from the database according to the temperature difference, and the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is electrically heated according to the first current. Among them, the temperature difference is positively correlated with the first current. It can be understood that the greater the temperature difference, the greater the temperature increase required, and the greater the corresponding first current.

[0061] Optionally, the electronic device determines a first current according to the temperature difference, and electrically heats the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature according to the first current, and stops heating when the temperature difference is less than or equal to a preset temperature difference.

[0062] Optionally, when the currently determined first temperature difference is greater than the preset temperature difference, the electronic device determines a first current corresponding to the first temperature difference based on the first temperature difference, and electrically heats the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature according to the first current corresponding to the first temperature difference; when the electronic device obtains the first temperature and the second temperature collected next time, when the second temperature difference between the first temperature and the second temperature is greater than the preset temperature, the first current corresponding to the second temperature difference is determined based on the second temperature difference, and then the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is electrically heated according to the first current corresponding to the second temperature difference; when the first temperature and the second temperature collected next time are obtained, when the second temperature difference between the first temperature and the second temperature is greater than the preset temperature, the first current corresponding to the second temperature difference is determined based on the second temperature difference, and then the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is electrically heated according to the first current corresponding to the second temperature difference; when obtaining the first temperature and the second temperature collected by subsequent sensors, the same processing flow is adopted, which will not be repeated here.

[0063] In an optional embodiment, if Figure 4As shown, the electronic device obtains the first temperature collected by the first sensor and the second temperature collected by the second sensor, and determines the temperature difference between the first side and the second side of the camera lens according to the first temperature and the second temperature. When the temperature difference is greater than the preset temperature difference, the first current is determined according to the corresponding relationship between the temperature difference and the first current, and the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is energized and heated according to the first current to obtain the heating film temperature. The electronic device adjusts the first current according to the heating film temperature to control the temperature of the corresponding heating film to always be within a suitable temperature range. Optionally, the first current is adjusted according to the temperature difference between the heating film temperature and the ambient temperature, for example, according to the relationship between the temperature difference between the heating film temperature and the ambient temperature and the current adjustment amount, according to the temperature difference between the heating film temperature and the ambient temperature, the current adjustment amount is determined, thereby adjusting the first current by the corresponding current adjustment amount. Wherein, the ambient temperature may refer to the air temperature of the corresponding side that is not directly in contact with the heating film, for example, the air temperature at a preset distance from the heating film on the corresponding side.

[0064] Optionally, the collection frequency of the first temperature and the second temperature is lower than the collection frequency of the heating film temperature, that is, after the first current is determined by collecting the first temperature and the second temperature once, the heating film temperature can be collected multiple times to adjust the first current multiple times. It can be understood that when the heating film temperature is higher than the ambient temperature, the first current is reduced accordingly; when the heating film temperature is lower than the ambient temperature, the first current is increased accordingly. It should be noted that the thermal conductivity of the camera lens in this embodiment is low, thereby ensuring that the heating film temperatures on the first side and the second side of the camera lens do not affect each other.

[0065] The method for preventing fogging of the camera lens in the above embodiment determines the first current according to the temperature difference, and electrically heats the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature according to the first current. The heating film on the side corresponding to the higher temperature can be electrically heated by the first current, thereby achieving efficient regulation of the temperature of the heating film on the high-temperature side, thereby avoiding the formation of water fog when the high-temperature side of the camera lens is exposed to cold.

[0066] In some embodiments, heating the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature includes: electrically heating the heating film on the side corresponding to the higher temperature between the first temperature and the second temperature according to a preset second current.

[0067] In this embodiment, when the temperature difference is greater than the preset temperature difference, the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is electrically heated by the preset second current, and when it is detected that the temperature difference is not greater than the preset temperature difference, the heating of the heating film is stopped. The second current is set according to the application environment of the electronic device, and the second current can be used to conveniently realize the control of electrically heating the heating film on the high temperature side of the camera lens of the electronic device, and can also prevent the camera lens from generating water mist.

[0068] In one embodiment, there are multiple first sensors and multiple second sensors; obtaining a first temperature corresponding to the first sensor and a second temperature corresponding to the second sensor includes:

[0069] The first temperature is determined according to each first sub-temperature collected by the plurality of first sensors; and the second temperature is determined according to each second sub-temperature collected by the plurality of second sensors.

[0070] Optionally, without affecting the field of view of photographing, multiple first sensors and multiple second sensors may be respectively arranged at different positions on both sides of the camera lens, for example, multiple first sensors may be evenly arranged on the outer edge of the first side of the camera lens, and multiple second sensors may be evenly arranged on the outer edge of the second side of the camera lens. The electronic device may determine the first temperature according to each first sub-temperature collected by the multiple first sensors, and determine the second temperature according to each second sub-temperature collected by the multiple second sensors, for example, the arithmetic mean, weighted average, maximum value, minimum value or middle value of each first sub-temperature collected by the multiple first sensors may be used as the first temperature; similarly, the arithmetic mean, weighted average, maximum value, minimum value or middle value of each second sub-temperature collected by the multiple second sensors may be used as the second temperature.

[0071] In this embodiment, by setting up multiple first sensors and multiple second sensors, the first temperature is determined according to the first sub-temperatures collected by the multiple first sensors, and the second temperature is determined according to the second sub-temperatures collected by the multiple second sensors. A more accurate temperature value that can actually reflect the temperatures on both sides of the camera lens can be obtained, thereby determining a more accurate temperature difference, heating the heating film on the side corresponding to the higher temperature, and more accurately preventing the camera lens from fogging.

[0072] In one embodiment, the camera device includes a camera lens, and a first thermistor located on a first side of the camera lens and a second thermistor located on a second side, and the first side surface and the second side surface of the camera lens are covered with a conductive heating film. When the camera device is started, the first thermistor and the second thermistor start working, and the electronic device obtains the first temperature collected by the first thermistor and the second temperature collected by the second thermistor; when the first temperature is 3°C higher than the second temperature, it is determined that the current scene is likely to cause water mist to form on the first side surface of the camera lens, and the electronic device controls the conductive heating film on the first side surface to be energized and heated, wherein the energized current is determined according to the relationship between the predetermined temperature difference and the first current, so that the temperature of the first side surface is increased to prevent the first side surface from generating water mist when it is cold; when the second temperature is 3°C higher than the first temperature, it is determined that the current scene is likely to cause water mist to form on the second side surface of the camera lens, and the electronic device controls the conductive heating film on the second side surface to be energized and heated, wherein the energized current is determined according to the relationship between the predetermined temperature difference and the first current, so that the temperature of the second side surface is increased to prevent the second side surface from generating water mist when it is cold.

The camera lens 502 is a transparent lens on an electronic device that protects the camera sensor. The material of the camera lens 502 can be glass or plastic. In order not to affect the effect of the camera sensor acquiring visible light for imaging, the light transmittance of the camera lens is greater than the preset transmittance. Further, the light transmittance of the first heating film located on the first side surface of the camera lens 502 and the second heating film located on the second side surface also need to be greater than the preset transmittance. The preset transmittance can be set according to the imaging requirements of the camera sensor, for example, the preset transmittance is 90%. It should be noted that the first side surface and the second side surface of the camera lens 502 in this embodiment refer to the planes perpendicular to the light entering the camera lens during shooting.

[0078] The above-mentioned camera device can obtain the first temperature collected by the first sensor and the second temperature collected by the second sensor, and determine the temperature difference between the first side and the second side of the camera lens according to the first temperature and the second temperature. When the temperature difference is greater than the preset temperature difference, the heating film on the side corresponding to the higher temperature of the first temperature and the second temperature is heated. The heating film on the corresponding side heats up, which can effectively prevent the corresponding side surface of the camera lens from generating water mist when it is cold.

[0082] Optionally, the heating film can be formed by hot pressing conductive ink and metal current-carrying strips between insulating polyester films after processing. For example, the heating film is a film of a preset thickness formed by hot pressing a heating material into a polyimide film (PI film).
