[0002] Camera components are prone to overheating the lens in high temperature environments, which affects the camera's imaging quality and is prone to image distortion, color distortion and other problems. In addition to the high temperature of the lens component itself, the ambient temperature around the camera will also affect the imaging quality.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Because the internal structure of the steam oven is complex, a variety of light sources will be generated during the working process. In addition to the oven light, the light from the carbon fiber tube unique to the oven will also affect the normal operation of the camera. The surface color temperature of the food will also change as the temperature of the food changes. Through the automatic temperature adjustment of the lens and the use of automatic focus to adjust the focus ring ratio, optimize the ambient light source, and adjust the white balance and color temperature deviation of the camera during operation. To ensure that the camera can work and shoot normally, so that users can see high-quality, undistorted images of the cooking process. In summary, the blurry image of the camera at high temperature is mainly caused by reasons such as excessively high lens temperature and excessively high ambient temperature around the lens. Appropriate preventive measures and solutions should be taken during use to ensure the normal use of the camera.

[0052] In the relevant technology, high-temperature resistant materials, high-definition heat-insulating glass and small electronic fan equipment can be used to control the camera temperature within the standard range. This can indeed optimize the most basic temperature range requirements of the camera device itself. However, it only protects the appearance and material of the camera device itself from the perspective of structure and material. The camera's imaging will still be affected by temperature.

[0053] One of the core concepts of the embodiment of the present invention is to obtain the temperature change value data of the external and internal temperature by using the temperature sensor chip, and transmit the temperature change value to the temperature control module through the temperature detection module. The internal temperature is controlled within the threshold range (between 0°C and 60°C) to achieve the temperature adjustment of the camera acquisition device, thereby avoiding the image blur caused by high temperature to ensure the imaging effect. To ensure that the user can see the high-quality and authentic picture and video of a normal baking process during the high-temperature steaming and baking process of the steam oven.

[0054] Reference Figure 1 , shows a flow chart of the steps of a control method of a cooking device provided by an embodiment of the present invention, wherein the cooking device includes an image acquisition module, a temperature detection module and a temperature control module arranged inside, and the method may specifically include the following steps:

[0055] Step 101, during the cooking process of the cooking device, obtaining the working temperature of the image acquisition module detected by the temperature detection module;

[0056] As a household cooking device that combines the functions of a traditional steamer and an oven, the steam oven has gradually become an indispensable part of the kitchen in recent years. It not only provides traditional steam cooking methods, but also realizes multiple heating modes such as baking and grilling. Some models even support unique functions such as steam tender baking. This versatility allows the steam oven to meet the daily cooking needs of the family while also bringing more creative space to users.

[0057] With the advancement of the Internet of Things and artificial intelligence technologies, more and more smart devices are beginning to be integrated into family life. Modern steam ovens often integrate smart technologies, such as built-in cameras, Wi-Fi connections, and supporting applications. Users can remotely control the device through their mobile phones, view the status of food in real time, and receive push notifications to remind cooking progress, making cooking more intuitive, convenient and fun.

[0058] The main purpose of the built-in camera in the steam oven is to allow users to remotely monitor the cooking status of food without having to frequently open the oven door to check the progress. For example, some cameras in the oven can record the entire baking process of food and upload the video to the corresponding application. At the same time, it can also identify what type of food is placed inside the oven. This means that even if you are not in the kitchen, users can check the status of food through their mobile phones or other connected devices to avoid affecting the final effect due to over- or under-cooking.

[0059] In addition to simple monitoring, some high-level smart steam ovens also incorporate AI (artificial intelligence) technology to achieve automatic identification of food types and adjust cooking parameters according to the weight of the food. This intelligent design greatly simplifies the user's operation process, especially for those who are not familiar with baking skills, providing great convenience. For example, when the user puts in a piece of chicken breast, the oven can measure its mass through the built-in sensor and set the optimal temperature and time accordingly, ensuring perfect cooking results every time.

[0060] From the perspective of user experience, smart ovens with cameras bring unprecedented interactivity and sharing. Many models support one-click time-lapse photography, allowing users to easily record the key moments of food preparation and share them with friends and family through social media platforms. This is especially attractive to young people who like to try new things or are keen on social networks. In addition, some steam ovens also support regular updates of built-in application content, providing more diverse recipe guidance and support to help users continuously improve their cooking skills.

[0061] However, installing and maintaining the camera in a high-temperature environment is a technical challenge. Ordinary electronic components cannot withstand heat above a certain limit and cannot continuously capture high-quality images under extreme conditions. When the temperature inside the steam oven rises to 270 degrees Celsius or higher, ordinary electronic devices may be permanently damaged due to overheating.

[0062] For cameras, exposure to such extreme temperatures can cause not only performance degradation but even complete failure of the camera's lens, sensor, and other critical components. Even if the camera itself is not directly heated to dangerous levels, strong light and reflections from inside the oven can interfere with imaging. Especially when using the steam function, the generated water vapor can form condensation droplets on the lens surface, causing blurry images.

[0063] In addition, prolonged exposure to high humidity may accelerate the lens aging process. Continuous high temperatures may cause certain non-metallic materials (such as plastic casings) to soften or deform, which in turn affects the overall structural stability of the camera and the firmness of its connection with the host. This will not only weaken the safety of the device, but may also cause problems such as data transmission interruption.

[0064] In some embodiments of the present invention, the cooking device refers to a steam oven or an oven, and the image acquisition module may refer to a camera, etc., for capturing images of food. The camera installation position in the steam oven depends on the specific model and design, but there are usually several common installation position options to ensure the best visual monitoring effect and safe operation of the device.

[0065] Mounting the camera on the inside of the oven door reduces the impact of direct high temperatures, as the glass door itself provides some insulation. This layout also helps protect the camera from direct splashes of food or liquid, which is suitable for most household ovens, especially those that emphasize user-friendliness and safety.

[0066] When the camera is located at the top or side of the cavity, it can provide a wider viewing angle, covering the entire cooking area, allowing users to fully understand the status of the food. This arrangement helps prevent the camera lens from being blocked by steam condensation. It is suitable for professional kitchen equipment that requires all-round monitoring of the cooking process or high-end household models that have high requirements for cooking effects.

[0067] Some designs may place the camera near the bottom heating element, which not only makes efficient use of space but also allows the camera to better capture the image of the food placed on the baking sheet. Due to its proximity to the heat source, this installation method places higher demands on the camera's heat resistance and may require additional heat dissipation measures to ensure its normal operation.

[0068] Some advanced steam ovens may be equipped with multiple cameras, which are installed in different positions to provide a more comprehensive view. For example, one camera is responsible for monitoring the food on the upper layer, while another focuses on the lower layer. This approach can significantly improve the user experience, especially when processing multiple ingredients at the same time. This approach is particularly suitable for large commercial steam ovens or high-end home equipment, providing users with more diversified monitoring options.

[0069] In the embodiment of the present invention, the working temperature of the steam oven image acquisition module is the ambient temperature around the camera installation position. Regardless of the installation method and position, it is generally within the cavity inside the steam oven. Measuring and obtaining the working ambient temperature of the camera is extremely important for the imaging effect.

[0070] Although the camera itself is not involved in temperature measurement, the steam oven is usually equipped with one or more temperature measuring elements. The temperature measuring elements in the steam oven are crucial to ensure temperature control during the cooking process. These elements not only determine whether the equipment can accurately maintain the set temperature, but also affect the quality and taste of the final food. Some common temperature measuring elements are as follows:

[0071] NTC thermistor is one of the most commonly used temperature measuring components. Its working principle is based on the characteristic that the resistance value changes with temperature. When the temperature rises, the resistance value of the NTC thermistor will decrease; conversely, when the temperature drops, the resistance value increases. This characteristic allows it to respond to temperature changes very sensitively and convert temperature information into electrical signals and output them to the control system. It has the advantages of low cost, fast response speed and high accuracy. High-precision NTC (negative temperature coefficient) temperature probes, which can sense the temperature changes in the cavity in real time and feed the data back to the control system. These temperature probes can be distributed throughout the cavity to ensure that every corner can be evenly heated.

[0072] Zirconia oxygen sensors, although the name contains "oxygen", can also be used to indirectly measure humidity. This is because they can detect changes in the partial pressure of oxygen in the air, and in a closed space, the presence of water vapor will affect this value. The water vapor partial pressure is calculated using Dalton's law, and the high-temperature water vapor content is obtained. This type of sensor can operate at extremely high temperatures (such as 300-400°C) and does not consume the measured gas.

[0073] Fiber optic temperature sensors use optical signals instead of electrical signals to measure temperature. They have good resistance to electromagnetic interference and can achieve long-distance transmission. In addition, since the optical fiber itself is made of non-metallic materials, it can maintain stable performance under extreme conditions, such as high temperature or corrosive environments. It is not affected by electromagnetic interference and is suitable for temperature monitoring in special occasions.

[0074] The temperature probe is usually a direct contact design, installed in different locations inside the steam oven to detect the temperature around the heating tube. This data is then transmitted to the temperature controller, which decides when to turn on or off the heating element according to the preset target temperature to achieve a constant temperature effect. The more sensitive the temperature probe, the smaller the temperature difference of the entire system, thus ensuring a more uniform heating effect.

[0075] The specific material is selected according to the usage scenario, and can be used to obtain the operating temperature of the camera.

[0076] Step 102, when the operating temperature is greater than a preset temperature threshold, lowering the temperature of the image acquisition module through the temperature control module, and acquiring the light intensity detected by the image acquisition module;

[0077] Because the internal structure of the steam oven is complex, a variety of light sources are generated during the working process. In addition to the oven light, the light from the carbon fiber tube unique to the oven will also affect the normal operation of the camera. The surface color temperature of the food will also change as the temperature of the food changes. When the working temperature of the image acquisition module, that is, the camera, exceeds the preset temperature threshold, it will affect the effect of the camera taking pictures of the food. Therefore, the temperature of the image acquisition module is reduced through the temperature control module to restore it to a temperature range where it can work normally, so that the food image can be clearly taken.

[0078] Regarding the preset temperature, it can be set according to the material and structure of the camera. For example, the preset temperature threshold can generally be set to 60 degrees Celsius. When the internal temperature of the steam oven rises above 60 degrees Celsius as the food is steamed or baked, the temperature control module starts to cool the camera.

[0079] Common ways to cool down electrical components include: natural convection heat dissipation, using the natural flow of air to take away heat. When an electrical component heats up, the surrounding air will rise due to the increase in temperature, and cold air will be added to form a convection cycle; forced air cooling heat dissipation, using active devices such as fans to accelerate air flow and improve heat exchange efficiency; liquid cooling heat dissipation, using liquid as a cooling medium, directly contacting the heating element or indirectly transferring heat to an external radiator through a heat pipe for cooling. The specific heat capacity of liquid is usually higher than that of air, so its heat absorption capacity is stronger; heat pipe heat dissipation, a heat pipe is an efficient heat transfer element filled with a small amount of working fluid (such as water). After one end of it absorbs heat close to the heat source, the working fluid evaporates and moves along the pipe wall to the other end to release heat and recondense, and this cycle is repeated to achieve rapid heat dissipation; phase change material (PCM, Phase Change Material) heat dissipation, phase change materials can change from solid to liquid or vice versa within a specific temperature range, absorbing or releasing a large amount of latent heat in the process, thereby achieving the purpose of heat dissipation; conduction heat dissipation, directly conducting heat away from the heating element through a metal substrate or other materials with good thermal conductivity. This is usually the basis for other cooling methods; composite cooling combines two or more of the above methods to achieve better cooling effects, such as air-cooled heating tube combination, liquid cooling and PCM combination, etc.

[0080] In the embodiment of the present invention, the hardware cooling method used is to use the heat dissipation accessories to quickly conduct the heat away or the heat dissipation back clip to cool the camera through air cooling.

[0081] Because the light energy generated by the high light in the working environment will be converted into heat energy, and the camera device will absorb the heat energy generated by the ambient light, thereby increasing the temperature inside the camera device body. For example, the light energy generated by the light generated by the steam oven during operation will be converted into heat energy, causing the temperature inside the camera device body to rise. The position where the camera lens is focused is exactly the position where the light intensity is the highest, so it is necessary to obtain the light intensity detected by the camera, and the temperature control module will automatically adjust the position and angle of weak light according to the source of ambient light to prevent the imaging effect of the captured image due to excessive ambient light.

[0082] Step 103: adjusting the shooting angle of the image acquisition module according to the light intensity, and adjusting the image processing mode of the image acquisition module after the shooting angle is adjusted.

[0083] According to the detected light intensity of the camera working environment, if the ambient light is too strong or too dark, the camera shooting angle needs to be automatically enhanced or automatically rotated, and the focal length and focus setting of the lens are adjusted through the camera. After the captured image signal is converted into a digital signal, image preprocessing is performed. The camera module receives the light intensity of different light sources from the working environment, and determines whether the focus is adjusted to the optimal value based on the display image obtained by the lens chip.

[0084] For example, the results of the changes in pixel grayscale, surface texture, color and volume shape of the food images captured by the camera in the steam oven, and the recognition results of the above parameters are processed and analyzed by the image processing chip including the non-uniform correction module and the image filtering and denoising module to remove noise, enhance the image quality contrast, and perform color correction on the high-frequency image enhancement image. The color sensor cooperates with the image processing chip to correct it again. After completing the above image processing steps, the final image can be obtained.

[0085] The embodiment of the present invention introduces a control method for a cooking device. During the cooking process of the cooking device, the working temperature of the image acquisition module detected by the temperature detection module is obtained; when the working temperature is greater than the preset temperature threshold, the temperature of the image acquisition module is lowered by the temperature control module, and the light intensity detected by the image acquisition module is obtained; according to the light intensity, the shooting angle of the image acquisition module is adjusted, and after the shooting angle adjustment is completed, the image processing method of the image acquisition module is adjusted. Through the automatic temperature adjustment of the lens and the parameter adjustment of the captured image, it is ensured that the camera can work and shoot normally, so that the user can see the high-quality, undistorted picture image of the cooking process.

[0086] Reference Figure 2 , shows a flowchart of another method for controlling a cooking device provided by an embodiment of the present invention, wherein the cooking device includes an image acquisition module, a temperature detection module, a temperature control module and a display module disposed inside the cooking device, and the method may specifically include the following steps:

[0087] Step 201, during the cooking process of the cooking device, obtaining the working temperature of the image acquisition module detected by the temperature detection module;

[0088] The temperature detection module includes a temperature sensor that can sense temperature changes and convert them into output signals for sensing external and internal temperature change value data. Sensing external temperature changes means, for example, the temperature of the steam oven space. The temperature sensor can monitor the temperature of the steam oven space in real time, helping the camera to obtain judgments due to changes in the temperature data of the steam oven space. When the temperature rises or falls, the material in the sensor (such as thermistors, whose resistance value changes with temperature) will undergo physical changes, and then the supporting circuit will convert this change into an electrical signal.

[0089] Sensing internal temperature refers to the temperature of the environment in which the components inside the camera body (such as lenses, image sensors, circuit boards, etc.) are located. Because components generate heat during long-term operation. The temperature sensor is installed inside the camera body to monitor the temperature of each component during operation. If the temperature of the image sensor is too high, the sensor will transmit this information to the system's temperature control system to start heat dissipation and cooling, or suspend the camera to ensure that it works within a safe temperature range. It is important to keep the internal temperature within a reasonable range, otherwise it may affect the performance and service life of the camera.

[0090] In some embodiments of the present invention, the image acquisition module includes a signal processing module, and the step 201 includes the following sub-steps:

[0091] The signal processing module receives the electrical signal of the working temperature inside the cooking device detected by the temperature detection module; the electrical signal is filtered and a digital signal of the working temperature is generated according to the filtered electrical signal.

[0092] After the temperature is detected by the temperature sensor, the output signal will have some interference factors, such as noise signals generated by environmental electromagnetic interference. These interference noises are removed from the electrical signal containing temperature information output by the temperature sensor, so that the final signal can more accurately reflect the actual temperature situation, which is convenient for subsequent accurate collection, display and corresponding control of temperature data.

[0093] The temperature value obtained by the temperature sensor is processed through signal filtering technology, and the interference noise is removed from the electrical signal containing temperature information output by the temperature sensor using a suitable filtering circuit, and converted into a digital signal so that the temperature control module can recognize and process the signal, facilitating subsequent accurate collection, display and corresponding control of temperature data.

[0094] Step 202, when the operating temperature is greater than a preset temperature threshold, lowering the temperature of the image acquisition module through the temperature control module, and acquiring the light intensity detected by the image acquisition module;

[0095] In some embodiments of the present invention, the temperature control module is a heat sink, and step 202 includes the following sub-steps:

[0096] The working current of the heat sink is controlled so that the heat sink cools the image acquisition module.

[0097] When the temperature of the camera exceeds the preset temperature threshold of 60 degrees Celsius, the temperature control module uses an algorithm that automatically adjusts the working current and heat dissipation temperature of the refrigeration chip to control the internal temperature within the threshold range (between 0°C and 60°C) to adjust the camera's working temperature, thereby avoiding image blur caused by high temperature and ensuring the imaging effect.

[0098] The algorithm for automatically adjusting the working current of the cooling plate (ie, thermoelectric cooler, TEC) to control the heat dissipation temperature refers to the process of dynamically adjusting the current applied to the TEC according to environmental conditions, load requirements, target temperature and other factors through a series of predefined operation steps and logical judgments, thereby achieving precise control of the TEC cold or hot end temperature. This algorithm usually contains several key elements:

[0099] Temperature sensing and feedback: In order to ensure the accuracy of temperature control, it is necessary to accurately measure the current temperature value. This usually involves installing one or more high-precision temperature sensors (such as NTC thermistors) near the TEC, which can monitor the temperature difference between the cold end, the hot end, or the two in real time and feed the data back to the control system.

[0100] Set point and error calculation: Based on the user-defined target temperature (called the set point), the control system compares the difference between the actual measured temperature and the desired value, which is called the "error." This error value is the basis for all subsequent control actions, determining whether the current needs to be increased or decreased to approach the target temperature.

[0101] Control: The proportional-integral-derivative (PID) controller is a widely used control strategy that adjusts the output signal based on the rate of change of the error and its cumulative history, thereby changing the current intensity input to the TEC. The advantage of PID control is that it can quickly respond to transient changes while avoiding excessive oscillations, ensuring that the system stably reaches and maintains the required temperature level. P (Proportional) proportional control directly adjusts the output in proportion to the current error, providing immediate but potentially less precise correction; I (Integral) integral control accumulates compensation for small errors that exist for a long time, helping to eliminate static deviations and making the long-term average temperature closer to the set point; D (Derivative) differential control responds in advance based on the speed of error change to prevent overshoot and improve the response speed and stability of the system.

[0102] The algorithm for automatically adjusting the working current and heat dissipation temperature of the cooling plate is a complex and precise process. It combines hardware sensing, software logic, mathematical models and other aspects to provide users with efficient and reliable temperature control solutions. When the temperature value is higher than 60℃, the temperature control module starts cooling control to control the temperature of the camera working environment below the preset temperature threshold, that is, between 0℃ and 60℃, to prevent camera failure or imaging distortion due to excessive temperature.

[0103] Step 203: adjusting the shooting angle of the image acquisition module according to the light intensity, and adjusting the image processing mode of the image acquisition module after the shooting angle is adjusted.

[0104] In some embodiments of the present invention, step 203 includes the following sub-steps:

[0105] If the light intensity is greater than a preset first light intensity threshold, adjusting the focus position of the image acquisition module to reduce the light intensity detected by the image acquisition module;

[0106] If the light intensity is less than a preset second light intensity threshold, the focus position of the image acquisition module is adjusted to increase the light intensity detected by the image acquisition module; the preset second light intensity threshold is less than the preset first light intensity threshold.

[0107] The range of light intensity when the camera is shooting is an important parameter that determines the camera's ability to capture clear images under different lighting conditions. Light intensity is usually measured in Lux (Lx), where 1 Lux is equal to 1 lumen of light per square meter. For a camera, its minimum and maximum acceptable light intensity directly affects the application scenario and technical performance of the device.

[0108] For the shooting capability in low-light environments, camera manufacturers usually provide a minimum light intensity value. The lower the value, the better the camera can work in darker environments. For example, ordinary cameras may require a light intensity of 0.1Lux or higher to produce usable images; low-light cameras can work under light conditions of 0.01Lux or even lower, and such cameras are suitable for night monitoring or other occasions with insufficient light1; starlight cameras can capture clear images in extremely low light environments of 0.001Lux and below; infrared integrated zero-light cameras can perform effective monitoring even in the absence of visible light, relying on built-in infrared lights.

[0109] On the other hand, the camera also has a maximum light intensity limit. When the light is too strong, it may cause overexposure of the image, loss of details, or even damage to the photosensitive element. Although in most cases there will be no problem exceeding this limit, in some special applications (such as outdoor direct sunlight), it is very important to ensure that the camera does not fail due to overexposure.

[0110] Therefore, when the camera is shooting, it is necessary to pay attention to the minimum light intensity and the maximum light intensity. If the light intensity is lower than the minimum light intensity threshold, or higher than the maximum light intensity threshold, the focal length and focus position of the camera should be adjusted to ensure that high-quality food images can be captured in the expected working environment. For example, the minimum light intensity threshold can be 1000 lux, and the maximum light intensity threshold can be 30,000 lux. The specific intensity can also be adjusted based on the average light level in the specific application scenario and other related factors, such as dynamic range, signal-to-noise ratio, etc.

[0111] In some embodiments of the present invention, the image acquisition module includes an image processing module, and step 203 further includes the following sub-steps:

[0112] The quality parameters of the image acquired by the image acquisition module are corrected by the image processing module.

[0113] The food image captured by the camera is converted into an electrical signal by the image processing module, which converts the light signal refracted by the optical lens into an electrical signal. For example, when light shines on the pixel of the image sensor, the charge signal generated records the image information content.

[0114] The quality of an image can be determined by the following aspects: the three-dimensional sense of light and shadow in the image, which reflects the three-dimensional sense of the object through the light and dark changes; the texture of the object, the texture of the light is different for different objects. For example, the texture light of the beef object can be a smooth light refraction; the exposure of highlights and shadows, the brightest part of the image can retain details, not a large white area, and the shadow part also needs to have moving details. It is not a black area; the authenticity of color restoration; the contrast between light and dark, the contrast between the subject and the background should be natural, not too strong, resulting in loss of details in the shadow part, or overexposure of the highlights.

[0115] In some embodiments of the present invention, the image processing module corrects the image parameters according to the image quality. For example, the image sensor can more accurately capture the color information of the light. The image sensor is more accurate in capturing red, green and blue light, thereby making the color restoration more realistic. Secondly, the quality lens has better control over the transmittance and dispersion of light, which can reduce chromatic aberration and help the color restoration authenticity.

[0116] In addition, during the shooting process, the current ambient light conditions are not conducive to the shooting imaging effect. It is necessary to change the lighting conditions, adjust the camera's exposure parameters (such as exposure compensation, aperture, shutter speed) or adjust the light and dark contrast of the picture with software. For example, reducing the exposure can reduce the brightness of the bright part and increase the contrast. After completing the above image processing steps, the final image can be obtained.

[0117] In some embodiments of the present invention, step 203 includes the following sub-steps:

[0118] Determining target parameters of the image acquisition module, and reducing the target parameters to reduce power consumption of the image acquisition module;

[0119] Determine a target function of the image acquisition module, and disable the target function to reduce power consumption of the image acquisition module.

[0120] When the camera temperature exceeds the preset temperature threshold, the camera needs to be cooled down. Currently, the most common method in the industry is to start with the structure and material. In addition to real-time monitoring and management of the camera temperature hardware, the embodiment of the present invention also solves the problem through software methods.

[0121] For example, the target parameters can be the resolution and frame rate of the camera. Because higher resolution and high frame rate will increase the temperature of the camera, the resolution and high frame rate need to be adjusted to appropriate data, such as reducing from 1080P to 720P.

[0122] The target function can be special effects, filters, Bluetooth, positioning and other functions. For example, turning off special effects and filters will increase the processing power of the camera and cause heating; some smart steam ovens have remote control connections, such as WiFi, Bluetooth, positioning and other functions, which cause the device to continuously request connection signals and cause heating. By optimizing and reducing the transmission power of request connection signals and limiting the frequency of network transmission activities, and setting network connection sleep strategies, the camera can be reduced from heating caused by long-term transmission.

[0123] Or, because the camera has been in operation for a long time, it will generate a large amount of data, which will cause increased heat during operation. You can also set a schedule to regularly clean up the storage data of the camera application.

[0124] Step 204, obtaining the image processed by the image processing module, and displaying the image on the display module.

[0125] By transmitting the image after the above-mentioned image enhancement processing to the screen of the steam oven terminal device for displaying the picture content, the user can remotely monitor the cooking status of the food without having to frequently open the oven door to check the progress. Even if the user is not in the kitchen, the status of the food can be checked through a mobile phone or other networked devices to avoid affecting the final effect due to over- or under-cooking.

[0126] The embodiment of the present invention introduces a control method for a cooking device. During the cooking process of the cooking device, the working temperature of the image acquisition module detected by the temperature detection module is obtained; when the working temperature is greater than the preset temperature threshold, the temperature of the image acquisition module is lowered by the temperature control module, and the light intensity detected by the image acquisition module is obtained; according to the light intensity, the shooting angle of the image acquisition module is adjusted, and after the shooting angle adjustment is completed, the image processing method of the image acquisition module is adjusted. By automatically adjusting the temperature of the lens, adjusting the parameters of the captured image, and adjusting the setting parameters of the camera during operation, the camera can be ensured to work and shoot normally, so that the user can see high-quality, undistorted images of the cooking process.
