[0034] Embodiments of the present application will be described in detail below.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0035] Please refer to Figure 1 , the present application provides a control method for a cooking device. The control method includes:

[0036] 01: Obtain an initial picture taken inside the cooking device;

[0037] 03: Identify the layer where the cooking utensil is located inside the cooking device according to the initial picture;

[0038] 05: Control the brightness of the lighting device inside the cooking device according to the layer where the cooking utensil is located.

[0039] Please refer to Figure 2 , the present application also provides a control device 10 for a cooking device. The control device 10 includes: an acquisition module 11, a layer identification module 13, and a control module 15. The acquisition module 11 is used to obtain an initial picture taken inside the cooking device; the layer identification module 13 is used to identify the layer where the cooking utensil is located inside the cooking device according to the initial picture; the control module 15 is used to control the brightness of the lighting device inside the cooking device according to the layer where the cooking utensil is located.

[0040] Specifically, the cooking device of the present application may be, for example, an oven, a microwave oven, or other devices, which is not limited herein. The initial picture may be a picture taken when the control device is in the preview mode.

[0041] Such as Figure 3As shown, the layers where the cooking utensils are located in the cooking device can, for example, have a total of three layers, namely the first layer L1, the second layer L2, and the third layer L3. For the three layers of the cooking device, the control device 10 can capture three different initial pictures. For example, specifically, it can identify the layer where the cooking utensil is located in the current cooking device according to the different distances between the cooking utensil and a certain reference plane in the initial picture, or it can compare the features of the reference picture with pre-known layer information and the initial picture to identify the layer where the cooking utensil is located in the current cooking device.

[0042] After identifying the layer where the cooking utensil is located in the cooking device, the brightness of the lighting device in the cooking device can be controlled according to the layer where the cooking utensil is located, so that the brightness of the lighting device in the cooking device matches the layer of the cooking utensil, thereby solving the problem of overexposure of the imaging of the shooting device during the cooking process when using different layers in cooking devices such as ovens, and ensuring that the food pictures taken are not overexposed.

[0043] In this way, the control method of the present application can control the brightness of the lighting device in the cooking device according to the layer where the cooking utensil is located after identifying the layer where the cooking utensil is located in the cooking device, thereby solving the problem of overexposure of the imaging of the shooting device during the cooking process when using different layers in cooking devices such as ovens, and ensuring that the food pictures taken are not overexposed.

[0044] In some embodiments, step 01 includes:

[0045] 011: When the lighting device in the cooking device turns on the lighting with a preset brightness and the door of the cooking device is closed, control the shooting device in the cooking device to pre-capture an initial picture of the cooking device with a cooking utensil.

[0046] Please combine Figure 2 , step 011 can be implemented by the acquisition module 11. That is, the acquisition module 11 is used to control the shooting device in the cooking device to pre-capture an initial picture of the cooking device with a cooking utensil when the lighting device in the cooking device turns on the lighting with a preset brightness and the door of the cooking device is closed.

[0047] Specifically, the preset brightness can be default set to 100% Lx, or it can be other pre-set brightnesses.

[0048] Understandably, after the cooking utensil is placed in the cooking device, when it is confirmed that the cooking door is closed and the lighting device is turned on with a preset brightness, the shooting device can first preview and take a photo of the cooking device when there is a cooking utensil at the current layer, and then obtain an initial picture corresponding to the current cooking utensil at the current layer under the preset brightness, so that the control method of the present application can judge whether the picture of the food taken in the cooking utensil will be overexposed when the cooking door is closed according to the initial picture, ensuring that the picture of the food material taken during the cooking process will not be overexposed.

[0049] The shooting device is generally installed on the inner top wall, inner side wall of the cooking device or on the door body of the cooking device, and the lighting device is also generally installed on the inner top wall, inner side wall of the cooking device or on the door body of the cooking device accordingly, which is not limited here. Since the installation positions of the lighting device and the shooting device on the cooking device are fixed, the higher the layer where the cooking utensil is located in the cooking device, the greater the probability that the initial picture taken by the shooting device will be overexposed. Overexposure means that the brightness in the picture is too high, making the highlight part of the picture show white without details.

[0050] As Figure 3 shown, there can be three layers in total for the layer where the cooking utensil is located in the cooking device, namely the first layer L1, the second layer L2 and the third layer L3. For the three layers of the cooking device, in the case before cooking when the lighting device in the cooking device is turned on with a preset brightness and the door body of the cooking device is closed, the shooting device can respectively take three different initial pictures corresponding to the cooking utensil at the three layers in preview mode, so as to judge whether there is overexposure according to the initial pictures. If there is overexposure in the initial picture, the brightness of the lighting device can be adjusted so that the picture of the food taken by the shooting device during the cooking process will not be overexposed. If there is no overexposure in the initial picture, the brightness of the lighting device is not adjusted.

[0051] In this way, the control method of the present application can, before cooking, when the lighting device in the cooking device is turned on with a preset brightness and the door body of the cooking device is closed, control to pre-take an initial picture of the cooking device with a cooking utensil, so as to judge whether the brightness of the shooting device in the cooking device at this time is suitable for the layer where the current cooking utensil is located according to the initial picture, so that the shooting device will not have an overexposed imaging problem during the cooking process, ensuring that the picture of the food taken is not overexposed.

[0052] Please refer to Figure 4 , in some embodiments, step 011 includes:

[0053] 0111: Detect in real time whether the door body of the cooking device is opened;

[0054] 0112: If it is detected that the door body is opened, control the lighting device to turn on with a preset brightness;

[0055] 0113: Detect in real time whether the door body is closed;

[0056] 0114: If it is detected that the door body is closed, control the photographing device to pre - photograph an initial picture of the cooking utensils in the cooking device.

[0057] Please combine Figure 2 , step 0111, step 0112, step 0113 and step 0114 can all be implemented by the acquisition module 11. The acquisition module 11 is used to detect in real time whether the door body of the cooking device is opened; if it is detected that the door body is opened, control the lighting device to turn on with a preset brightness; detect in real time whether the door body is closed; if it is detected that the door body is closed, control the photographing device to pre - photograph an initial picture of the cooking utensils in the cooking device. The acquisition module 11 may include detection instruments such as a distance sensor.

[0058] Specifically, a distance sensor can be installed in the control device of the present application. The distance sensor can detect in real time whether the distance between the door body of the cooking device and the control device is greater than a preset threshold, so as to detect whether the door body is opened. If it is detected that the distance between the door body of the cooking device and the control device is greater than the preset distance threshold, the control device considers that the door body is opened at this time. If the distance sensor detects that the distance between the door body of the cooking device and the control device is equal to the preset distance threshold, the control device considers that the door body is in a closed state at this time. Among them, the preset distance threshold can be the initial measured distance when the door body of the cooking device is closed. The control method of the present application can, after confirming that the door body of the cooking device is opened, control the lighting device to turn on with a preset brightness, and in the case of detecting that the door body is closed, control the photographing device to photograph the cooking utensils in the cooking device to obtain an initial picture.

[0059] That is to say, the control method of the present application can automatically control the lighting device to turn on the lighting according to the opening and closing conditions of the door body, and automatically control the photographing device to photograph an initial picture of the cooking utensils in the cooking device.

[0060] In some embodiments, step 03 includes:

[0061] 031: Compare the features of the initial picture with the reference pictures in the preset database to identify the layer where the cooking utensils are located.

[0062] Please combine Figure 2 , step 031 can be implemented by the layer identification module 13. That is to say, the layer identification module 13 is used to compare the features of the initial picture with the reference pictures in the preset database to identify the layer where the cooking utensils are located.

[0063] Specifically, the preset database can be a part of the storage module pre-installed inside the control device. The reference pictures in the preset database are pictures taken in advance corresponding to the cooking utensils at different levels of the cooking device. That is to say, the preset database can include reference pictures and the level information of the cooking utensils in each reference picture.

[0064] In this application, the initial picture can be compared with the reference pictures in terms of features. If the features of the initial picture are the same as those of reference picture A, it can be determined that the level of the cooking utensil in the initial picture is the same as the level of the cooking utensil in reference picture A.

[0065] In this way, this application can identify the level where the cooking utensil is located by comparing the initial picture with the reference pictures in the preset database, and the method for identifying the level where the cooking utensil is located is simple and fast.

[0066] Please refer to Figure 5 , in some embodiments, the control method includes:

[0067] 021: When the lighting device turns on the lighting at a preset brightness and the door of the cooking device is closed, pre-take reference pictures of the cooking utensils at different levels in the cooking device;

[0068] 022: Store the reference pictures and the corresponding level information in the preset database.

[0069] Please refer to Figure 6 , the control device 10 of the cooking device further includes a storage module 12. Both step 021 and step 022 can be implemented by the storage module 12. That is to say, the storage module 12 is used to pre-take reference pictures of the cooking utensils at different levels in the cooking device when the lighting device turns on the lighting at a preset brightness and the door of the cooking device is closed; store the reference pictures and the corresponding level information in the preset database. Among them, step 021 and step 022 can be located before step 01, or before step 03, or before step 05, and no limitation is made here.

[0070] Specifically, in one embodiment, when the cooking device is an oven, the cooking utensil is a baking tray. There are a total of 3 layers of baking trays in the oven. The lighting device is a furnace lamp installed at the top of the oven, and the control device is a camera installed at the top of the oven. When the furnace lamp in the oven turns on the lighting at a preset brightness and the door is closed, the camera can pre-take 3 reference pictures of the cooking utensils at different levels in the 3 layers of the oven, namely reference picture 1 corresponding to the first layer from high to low, reference picture 2 corresponding to the second layer, and reference picture 3 corresponding to the third layer. The preset brightness can be default set to 100% Lx as described above, or it can be other preset brightnesses.

[0071] Then, three reference pictures, namely reference picture 1, reference picture 2, and reference picture 3, are stored in a preset database together with the corresponding layer information. The layer information includes the information that reference picture 1 corresponds to the first layer of the topmost layer of the oven, reference picture 2 corresponds to the second layer of the middle layer of the oven, and reference picture 3 corresponds to the third layer of the bottommost layer of the oven.

[0072] Understandably, at this time, the installation position of the photographing device should be the same as the installation position of the photographing device when the initial picture was taken.

[0073] In this way, in this application, reference pictures and corresponding layer information can be pre-stored in the preset database, facilitating subsequent feature comparison between the initial picture and the reference pictures, so as to identify the layer where the cooking utensil is located in the initial picture.

[0074] Please refer to Figure 7 , in some embodiments, step 05 includes:

[0075] 051: Determine whether the target brightness required for the layer-corresponding lighting device is the same as the preset brightness according to a preset mapping relation table; wherein, the preset mapping relation table includes the mapping relation between the layer of the cooking utensil and the brightness of the lighting device;

[0076] 052: If the target brightness required for the layer-corresponding lighting device is different from the preset brightness, then control and adjust the brightness of the lighting device to the target brightness;

[0077] 053: If the target brightness required for the layer-corresponding lighting device is the same as the preset brightness, then keep the brightness of the lighting device as the preset brightness.

[0078] Please combine with Figure 2 , steps 051, 052, and 053 can be implemented by the control module 15. That is, the control module 15 is used to determine whether the target brightness required for the layer-corresponding lighting device is the same as the preset brightness according to a preset mapping relation table; wherein, the preset mapping relation table includes the mapping relation between the layer of the cooking utensil and the brightness of the lighting device; if the target brightness required for the layer-corresponding lighting device is different from the preset brightness, then control and adjust the brightness of the lighting device to the target brightness; if the target brightness required for the layer-corresponding lighting device is the same as the preset brightness, then keep the brightness of the lighting device as the preset brightness.

[0079] Specifically, after identifying the layer where the cooking utensil is located in the cooking device, the control method of the present application can determine the target brightness of the lighting device in combination with a preset mapping relationship. If the target brightness is different from the preset brightness, the brightness of the lighting device can be adjusted in real time to the target brightness for lighting, so that the food ingredient pictures taken by the photographing device during the cooking process will not be overexposed. If the target brightness is the same as the preset brightness, it means that there is no need to adjust the brightness of the lighting device, and the lighting device can maintain lighting at the current preset brightness, and the food ingredient pictures taken by the photographing device during the cooking process will not be overexposed at this time.

[0080] Generally speaking, both the lighting device and the control device are located above the cooking utensil. The cooking device includes multiple layers from low to high. The mapping relationship between the layer of the cooking device and the brightness of the lighting device includes: the lower the layer of the cooking device, the brighter the brightness of the lighting device.

[0081] It can be understood that since the installation positions of the lighting device and the control device on the cooking device are both located above the cooking utensil and remain unchanged, the higher the layer where the cooking utensil is located in the cooking device, the greater the probability that the pictures taken by the photographing device will be overexposed. Therefore, the mapping relationship between the layer of the cooking device and the brightness of the lighting device can be set such that the higher the layer of the cooking device, the darker the lighting brightness of the configured lighting device. That is, the preset mapping relationship table can be obtained as shown in Table 1:

[0082] Table 1

[0083] Strata of the cooking utensil L1 L2 L3 Illumination brightness of the lighting device 100% Lx 80% Lx 40% Lx

[0084] In this way, the control method of the present application can solve the problem of overexposure of the imaging of the photographing device during the cooking process when using different layers in cooking devices such as ovens by identifying the layer of the cooking utensil in the cooking device and controlling and adjusting the lighting brightness of the lighting device according to the identified layer and the preset mapping relationship table, ensuring that the food pictures taken are not overexposed.

[0085] Please refer to Figure 8 , in some embodiments, before step 052, the control method further includes:

[0086] 041: Real-time detect whether the door body is opened for the second time within a preset time;

[0087] 042: If it is detected that the door body is not opened for the second time within the preset time, confirm that the brightness of the lighting device can be controlled and adjusted to the target brightness.

[0088] Please refer to Figure 9, the control device 10 of the cooking device further includes a detection module 14. Both step 041 and step 042 can be implemented by the detection module 14. That is to say, the detection module 14 is used to detect in real time whether the door body is opened a second time within a preset time; if it is detected that the door body is not opened a second time within the preset time, it is confirmed that the brightness of the lighting device can be controlled and adjusted to the target brightness.

[0089] Specifically, the preset time can be 3S, 5S, 6S, 7S, 8S, 9S, 13S, 15S, 18S or 20S, and there is no limitation here.

[0090] That is to say, before taking the target picture, it can also be confirmed first whether the door body has been in the closed state all the time within the preset time. If the door body is not opened a second time within the preset time to adjust the layer where the cooking utensil is located, it is confirmed that the brightness of the lighting device can be controlled and adjusted to the target brightness, ensuring that the food pictures taken by the shooting device during the cooking process will not be overexposed.

[0091] Please refer to Figure 10 , in some embodiments, the control method further includes:

[0092] 043: If it is detected that the door body is opened a second time within the preset time and it is detected that the door body is closed a second time, control to take a second picture of the cooking utensil in the cooking device;

[0093] 044: Re-identify the layer where the cooking utensil in the cooking device is located according to the second picture.

[0094] Please combine with Figure 9 , both step 043 and step 044 can be implemented by the detection module 14. That is to say, the detection module 14 is used to control to take a second picture of the cooking utensil in the cooking device if it is detected that the door body is opened a second time within the preset time and it is detected that the door body is closed a second time; re-identify the layer where the cooking utensil in the cooking device is located according to the second picture.

[0095] Specifically, the preset time can be 3S, 5S, 6S, 7S, 8S, 9S, 13S, 15S, 18S or 20S, and there is no limitation here.

[0096] That is to say, before taking the target picture, it can also be confirmed first whether the door body has been in the closed state all the time within the preset time. If the door body is opened a second time within the preset time to adjust the layer where the cooking utensil is located, then at this time, the lighting device is not controlled to illuminate at the target brightness and the control device is not controlled to take a target picture of the cooking utensil, but instead, the control device is controlled to take a second picture of the cooking utensil in the cooking device according to the preview mode, so as to re-identify the layer where the cooking utensil in the cooking device is located according to the second picture.

[0097] After re-identifying the layer where the cooking utensil is located in the cooking device, repeat the above steps to determine whether the target brightness required for the lighting device corresponding to the layer is the same as the preset brightness according to the preset mapping table, and detect whether the door is opened for the third time within the preset time. If it is not opened for the third time and they are different, control the lighting device to adjust its brightness to the target brightness, and so on. If it is detected that the door is opened for the third time within the preset time, repeat the above steps until it is detected that the door is not opened within the preset time. Through the above control method, the present application can enable the photographing device to obtain non-overexposed pictures during the cooking process.

[0098] Please refer to Figure 11 , in some embodiments, the control method further includes:

[0099] 032: Identify that the cooking utensil is located at multiple layers of the cooking device according to the initial picture;

[0100] 054: Determine the layer closest to the photographing device among the multiple layers;

[0101] 055: Determine whether the target brightness required for the lighting device corresponding to the layer closest to the photographing device is the same as the preset brightness according to the preset mapping table.

[0102] 056: If the target brightness required for the lighting device corresponding to the layer closest to the photographing device is different from the preset brightness, control the lighting device to adjust its brightness to the target brightness.

[0103] Please combine with Figure 2 , step 032 can be implemented by the layer identification module 13, and steps 054, 055, and 056 can be implemented by the control module 15. That is, the layer identification module 13 is used to identify that the cooking utensil is located at multiple layers of the cooking device according to the initial picture; the control module 15 is used to determine the layer closest to the photographing device among the multiple layers; and determine whether the target brightness required for the lighting device corresponding to the layer closest to the photographing device is the same as the preset brightness according to the preset mapping table. If the target brightness required for the lighting device corresponding to the layer closest to the photographing device is different from the preset brightness, control the lighting device to adjust its brightness to the target brightness.

[0104] It can be understood that when the photographing device is located above the cooking utensil, the initial picture taken by the photographing device may identify that the cooking utensil is located at different multiple layers. At this time, the control method of the present application can determine the target brightness of the lighting device according to the layer closest to the control device among the multiple layers.

[0105] For example, the cooking utensil includes a grill and a baking tray. A total of one layer of grill and a layer of baking tray located below the grill are placed in the oven to catch the oil dripping from the food on the grill. At this time, two levels including the first layer of grill and the second layer of baking tray with the distance control device from far to near will be recognized. If it can be known from the feature recognition of the initial picture that the first layer of grill is closer to the distance control device, the illumination brightness corresponding to the level of the first layer in the preset mapping relation table can be used as the target brightness of the illumination device.

[0106] That is to say, in the control method of the present application, if multiple levels of the cooking utensil in the cooking device are recognized in the initial picture, the level closest to the shooting device among the multiple levels is determined as the finally recognized level, and whether the target brightness corresponding to the finally recognized level is the same as the preset brightness is compared to determine whether it is necessary to adjust the brightness of the current illumination device.

[0107] In this way, when the target brightness required by the illumination device corresponding to the level closest to the shooting device is different from the current preset brightness, the control method of the present application can adjust the brightness of the illumination device to the corresponding target brightness, so as to solve the problem of overexposure of the image of the food taken by the shooting device during the cooking process of the cooking device and ensure that the taken picture is not overexposed.

[0108] In some embodiments, step 05 includes:

[0109] 057: Control the brightness of the illumination device to decrease as the level of the cooking utensil increases.

[0110] Please combine Figure 2 , step 057 can be implemented by the control module 15. The control module 15 is used to control the brightness of the illumination device to decrease as the level of the cooking utensil increases.

[0111] It can be understood that the illumination device is generally correspondingly installed on the inner top wall, inner side wall of the cooking device or on the door body of the cooking device, which is not limited here. When the level of the cooking utensil in the cooking device is higher, it is closer to the illumination device, and the brightness of the illumination device illuminating the cooking utensil is higher.

[0112] Therefore, the control method of the present application sets the brightness of the illumination device to decrease as the level of the cooking utensil in the cooking device increases, ensuring that when the cooking utensil is at a high level, it is not easy to have the problem of overexposure of the image of the food taken by the shooting device, and ensuring that the pictures taken during the cooking process of the cooking device are not overexposed.

[0113] In some embodiments, the control method includes:

[0114] 09: If the target brightness required by the illumination device corresponding to the level is the same as the preset brightness, control to keep the brightness of the illumination device at the preset brightness.

[0115] In combination with Figure 2 , step 09 can be implemented by the control module 15. The control module 15 is configured to control the illumination device to maintain the preset brightness if the target brightness required by the illumination device corresponding to the layer is the same as the preset brightness.

[0116] That is, if the target brightness of the illumination device required by the layer identified by the control method of the present application is the same as the preset brightness, there is no need to adjust the brightness of the illumination device, and the brightness of the illumination device can be directly maintained at the preset brightness.

[0117] The present application also provides a cooking device. The cooking device includes an illumination device and a control device. The control device is electrically connected to the illumination device, and the control device is configured to implement the control method of any one of the above embodiments.

[0118] Specifically, the control method is as described above and will not be elaborated here.

[0119] The cooking device of the present application applies the above control method to identify the layer of the cooking utensil in the cooking device and control and adjust the illumination brightness of the illumination device according to the identified layer and the preset mapping relation table, which can solve the problem of overexposure of the imaging of the photographing device during the cooking process when using different layers in cooking devices such as ovens, and ensure that the food pictures obtained by photographing are not overexposed.

[0120] The above embodiments merely represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
