Description

Technical Field

[0001] The present disclosure relates to a control method related to cooking (cooking) or a method for providing information related to cooking, etc. Background Art

[0002] In the past, as a control method related to cooking, a cooking method for improving the convenience of cooking has been proposed (for example, see Patent Document 1). In this cooking method, increase and decrease information indicating the increase and decrease of cooking ingredients is obtained from a cooking device (appliance), the increase and decrease information is converted into heat, and the heating time of the cooking device is adjusted according to the heat. For example, the increase and decrease information is obtained by photographing with a camera. As a result, the user can save the effort of adjusting the heating time according to the increase and decrease of cooking ingredients.

[0003] In addition, a cooking assistance system for assisting cooking has been proposed (for example, refer to Patent Document 2). The cooking assistance system is configured as smart glasses. The smart glasses determine the size of the food slices generated by the cook cutting the food, and based on the size of the food slices, estimate the heating cooking time that is most suitable for the food slices and display it. That is, in a control method related to cooking using smart glasses, the size of the food slices is determined and the heating cooking time is estimated. As a result, even if the cook cuts the food into a size different from the recipe, the cook can easily cook with the heating cooking time suitable for the size of the food slices obtained by the cutting.

[0034] (Insights from this disclosure)

[0035] When cooking, cooks sometimes consider the nutritional content of the dish obtained by cooking. The dish is, for example, bouillon, Japanese braised pork (stewed pork cubes), etc. The nutritional content is, for example, energy, the amount of nutrients, etc. Nutrients are, for example, protein, fat, carbohydrates, etc.

[0036] When cooking, by preparing food to be cooked including one or more ingredients according to the recipe of the dish and cooking the food to be cooked, a dish having energy corresponding to the recipe or a dish containing nutrients in amounts corresponding to the recipe can be prepared.

[0037] However, cooks sometimes want energy and nutrient amounts that are different from those described in a recipe. In addition, even if cooks want the energy and nutrient amounts described in a recipe, they cannot prepare the ingredients in the correct amounts according to the recipe, cannot prepare each ingredient at a ratio that matches the recipe, or even if they prepare each ingredient at a ratio that matches the recipe, the energy and nutrient amounts may change during the cooking process. In this case, it is difficult to appropriately set the temperature, pressure, time, etc. of the cooker for cooking the food as desired by the cook.

[0038] Therefore, the control method involved in the first technical solution of the present disclosure is a method executed by a computer to control a cooking device for cooking food, comprising: obtaining target nutrition information, the target nutrition information indicating a target with respect to one or more numerical values ​​related to the nutrition of a dish obtained by cooking the food; obtaining cooking parameter information including one or more cooking parameters for cooking by the cooking device based on the obtained target nutrition information; obtaining in-cooking nutrition information indicating one or more numerical values ​​related to the nutrition of the food when the cooking device is cooking; based on the target nutrition information and the in-cooking nutrition information, changing the cooking parameter information to modified cooking parameter information including one or more modified cooking parameters; and outputting a control signal including the modified cooking parameter information. In addition, the one or more nutrients may include protein, fat, etc., and may also include healthy ingredients such as melanoidin and edible gelatin.

[0039] Thus, for example, the target nutritional information desired by the cook is obtained, and the cooking parameter information is obtained based on the information, for example, as the initial cooking parameter information. Moreover, for example, by sending the cooking parameter information to the cooker, the cooker starts cooking according to the cooking parameter information. Thereafter, the cooking parameter information used for the cooker is changed according to one or more numerical values ​​(i.e., energy, etc.) related to the nutrition of the food being cooked during cooking. Therefore, by cooking according to the modified cooking parameter information, the energy of the dish finally made can be made close to the energy, etc. indicated by the target nutritional information. In other words, the energy of the dish finally made can be made close to the energy, etc. desired by the cook. That is, even if the energy, etc. desired by the cook is different from the energy, etc. described as the basic recipe, or even if the amount of the food being cooked is not as in the recipe, the energy of the final dish can be made close to the energy, etc. desired by the cook. As a result, the nutrition of the dish can be appropriately controlled without the cook intentionally adjusting the cooking parameters.

[0040] In addition, in the control method involved in the second technical solution subordinate to the first technical solution, it is also possible that, in acquiring the nutritional information during cooking, the nutritional information during cooking at a time point after a first time has passed since the start of cooking with the cooker is acquired as the first nutritional information, and the nutritional information during cooking at a time point after a second time has passed after the first time has passed since the start of cooking with the cooker is acquired as the second nutritional information, and in changing the cooking parameter information, the cooking parameter information is changed to the corrected cooking parameter information based on the difference between the first nutritional information and the second nutritional information and the target nutritional information.

[0041] Thus, the cooking parameter information is changed to the modified cooking parameter information based on the change amount of the nutritional information during cooking and the target nutritional information. Therefore, by considering the change tendency of energy, etc. caused by cooking according to the cooking parameter information, the energy, etc. of the final dish can be effectively made close to the energy, etc. desired by the cook. In addition, the first time can also be 0 hours. In this case, the first nutritional information represents one or more numerical values ​​related to the nutrition of the cooked food at the time point when cooking starts.

[0042] In addition, in the control method involved in the third technical solution subordinate to the first technical solution or the second technical solution, it is also possible to obtain third nutritional information, wherein the third nutritional information represents one or more numerical values ​​related to the nutrition of the dish obtained by cooking the dish by the cooker according to the modified cooking parameter information.

[0043] Thus, information indicating the energy of the final dish is estimated as the third nutritional information. Therefore, for example, by presenting the third nutritional information to the cook, the cook can confirm whether the dish containing the energy the cook wants can be made, or how close the energy of the final dish is to the expectation.

[0044] In addition, in the control method involved in the fourth technical solution belonging to any one of the first technical solution to the third technical solution, it is also possible that, in the change of the cooking parameter information, multiple candidates for the corrected cooking parameter information are obtained based on the target nutrition information and the nutrition information during cooking, and a candidate whose difference with the cooking parameter information is below a threshold or a candidate closest to the cooking parameter information is selected from the multiple candidates as the corrected cooking parameter information.

[0045] Thus, even when a plurality of new cooking parameter information are output as candidates by inputting the target nutrition information and the nutrition information during cooking into the learning model, for example, a candidate that is not much different from the original cooking parameter information (i.e., the initial cooking parameter information) is used as the corrected cooking parameter information. Therefore, the processing burden of the cooking device accompanying the change of the cooking parameter information can be reduced.

[0046] In addition, in the control method involved in the fifth technical solution subordinate to the third technical solution, it is also possible that, in obtaining the third nutritional information, the third nutritional information is obtained by at least inputting the corrected cooking parameter information into a learning model, and the learning model is machine-learned to output one or more numerical values ​​related to the nutrition of the dish obtained by cooking the dish according to the one or more cooking parameters by the cooker at least for the input of one or more cooking parameters changed during cooking by the cooker.

[0047] Therefore, since the learning model is used to obtain the third nutritional information, the third nutritional information with high accuracy can be obtained.

[0048] In addition, in the control method involved in the sixth technical solution belonging to any one of the first technical solution to the fifth technical solution, it is also possible that, in obtaining the nutritional information during cooking, the nutritional information during cooking is obtained by inputting at least one of an image of the food being cooked when the cooker is cooking, the weight of the food, and the amount of chemical components contained in the food into a learning model.

[0049] Therefore, since the learning model is used to obtain the nutritional information during cooking, it is possible to obtain the nutritional information during cooking with high accuracy.

[0050] In addition, in the control method involved in the seventh technical solution subordinate to the sixth technical solution, the learning model may also be machine-learned to output one or more numerical values ​​related to the nutrition of the one or more ingredients based on at least one input of an image of one or more ingredients being cooked in the cooker, a weight of the one or more ingredients, and a quantity of chemical components contained in the one or more ingredients.

[0051] Thus, by inputting at least one of the image of the food to be cooked, the weight of the food to be cooked, and the amount of chemical components contained in the food to be cooked into a learning model obtained by machine learning, it is possible to obtain highly accurate nutritional information during cooking from the learning model.

[0052] In addition, in the control method involved in the 8th technical solution belonging to any one of the 1st technical solution to the 7th technical solution, the one or more cooking parameters may include a parameter indicating the temperature used for cooking by the cooker and a parameter indicating the time used for cooking by the cooker.

[0053] Thereby, the nutrition of the dish obtained by grilling, for example, can be appropriately controlled.

[0054] In the control method according to the ninth aspect dependent upon the eighth aspect, the one or more cooking parameters may further include a parameter indicating a pressure used for cooking by the cooking device.

[0055] This makes it possible to appropriately control the nutrition of dishes obtained by, for example, steaming or boiling with pressure applied.

[0056] In addition, a technical solution of the present invention involves an information providing method in which a computer provides information related to cooking of a food to be cooked by a cooker, comprising: accepting target nutritional information based on a user's operation, the target nutritional information representing a target of one or more numerical values ​​related to the nutrition of a dish obtained by cooking the food to be cooked; and outputting final nutritional information derived from the target nutritional information and nutritional information during cooking, the nutritional information during cooking being information representing one or more numerical values ​​related to the nutrition of the dish when the cooker is cooking the food to be cooked.

[0057] Thus, for example, when receiving dish information representing a dish desired by a cook as a computer user and target nutritional information desired by the cook, one or more numerical values ​​(i.e., energy, etc.) related to the nutrition of the dish finally made based on this information can be prompted to the cook. Therefore, the cook can properly grasp the nutrition of the dish obtained by cooking. In other words, the cook can confirm whether a dish containing the energy desired by the cook can be made, or how close the energy of the dish finally made is to the desired one.

[0058] Furthermore, the processing actions included in the above-mentioned control method and information providing method are executed by a computer.

[0059] Hereinafter, the embodiments of the present disclosure will be described with reference to the accompanying drawings. The embodiments described below all represent a specific example of the present disclosure. Therefore, the numerical values, shapes, materials, constituent elements, configuration positions and connection forms of the constituent elements, etc. shown in the following embodiments are only examples and are not intended to limit the present disclosure.

For example, the server control unit 103 obtains the cooking state information 121 from the cooking device 300 via the server communication unit 105, and stores the cooking state information 121 in the second storage unit 120. In addition, the server control unit 103 obtains the nutritional information 131, the initial cooking parameter information 141, and the modified cooking parameter information 142 derived using the learning model set 150a. Furthermore, the server control unit 103 stores the obtained nutritional information 131 in the third storage unit 130, and stores the obtained initial cooking parameter information 141 and the modified cooking parameter information 142 in the fourth storage unit 140.

[0097] Figure 4 This is a diagram showing the details of the various types of nutritional information 131 stored in the third storage unit 130.

[0098] like Figure 4 As shown, a plurality of nutritional information 131 is stored in the third storage unit 130. The plurality of nutritional information 131 are target nutritional information 131a, first nutritional information 131b, second nutritional information 131c, and third nutritional information 131d, which will be described later. The target nutritional information 131a is nutritional information 131 that is a target for the cook. The first nutritional information 131b and the second nutritional information 131c are nutritional information 131 of the food being cooked, also referred to as nutritional information during cooking. The third nutritional information 131d is nutritional information 131 of the dish made by cooking, also referred to as final nutritional information.

[0099] Figure 5 This is a block diagram showing an example of a detailed functional configuration of the server control unit 103 .

[0100] The server control unit 103 includes an input acquisition unit 1031 , a parameter acquisition unit 1032 , a nutrition information acquisition unit 1033 , a parameter correction unit 1034 , a processing unit 1035 , and a parameter output unit 1037 .

[0101] The input acquisition unit 1031 acquires input information from the operation terminal 200 via the server communication unit 105. The input information is information received by the terminal control unit 203 through an input operation performed by the cook on the input unit 201 of the operation terminal 200. The cook performs an input operation on the input unit 201 of the operation terminal 200, for example, inputting the name of a dish prepared by the cooking device 300 (i.e., the dish name) and a target value related to nutrition. As a result, the terminal control unit 203 receives input information including the dish information indicating the dish name and the target nutrition information 131a indicating the target value related to nutrition. The input acquisition unit 1031 acquires the input information from the terminal control unit 203 via the terminal communication unit 205 and the server communication unit 105.

[0102] That is, the input acquisition unit 1031 in this embodiment acquires dish information indicating a dish obtained by cooking the food to be cooked and (b) target nutrition information 131a indicating targets with respect to one or more numerical values ​​related to nutrition.

[0103] The parameter acquisition unit 1032 acquires cooking parameter information indicating one or more cooking parameters using the input information and the learning model set 150a stored in the model storage unit 150. That is, the parameter acquisition unit 1032 acquires cooking parameter information including one or more cooking parameters for cooking by the cooker 300 based on the above-mentioned dish information and target nutritional information 131a acquired by the input acquisition unit 1031 using the learning model set 150a. The cooking parameter information is the initial cooking parameter information 141. In addition, in the present embodiment, the one or more cooking parameters include a cooking parameter indicating the temperature used for cooking by the cooker 300 and a cooking parameter indicating the time used for cooking by the cooker 300. Furthermore, the one or more cooking parameters include a cooking parameter indicating the pressure used for cooking by the cooker 300.

[0104] The parameter output unit 1037 transmits the initial cooking parameter information 141 to the cooking device 300 via the server communication unit 105. When the cooking unit 320 of the cooking device 300 obtains the transmitted initial cooking parameter information 141 via the cooking communication unit 305, it starts cooking according to the initial cooking parameter information 141.

[0105] The nutrition information acquisition unit 1033 acquires the nutrition information 131, for example, using the cooking state information 121 stored in the second storage unit 120 and the learning model set 150a stored in the model storage unit 150. The nutrition information 131 thus acquired represents one or more numerical values ​​related to the nutrition of the food being cooked while the cooking device 300 is cooking, and is also referred to as the in-cooking nutrition information (i.e., the first nutrition information 131b or the second nutrition information 131c). That is, the nutrition information acquisition unit 1033 acquires the in-cooking nutrition information representing one or more numerical values ​​related to the nutrition of the food being cooked while the cooking device 300 is cooking the food according to the cooking parameter information.

[0106] The parameter correction unit 1034 changes the initial cooking parameter information 141 into the modified cooking parameter information 142 including one or more modified cooking parameters based on the target nutrition information 131a and the nutrition information during cooking. In other words, the parameter correction unit 1034 corrects the initial cooking parameter information 141 into the modified cooking parameter information 142. In the correction of the initial cooking parameter information 141, the learning model set 150a stored in the model storage unit 150 is used.

[0107] The parameter output unit 1037 outputs a control signal including the modified cooking parameter information 142 to the cooking device 300 via the server communication unit 105. In other words, the parameter output unit 1037 transmits a control signal including the modified cooking parameter information 142. When the cooking unit 320 of the cooking device 300 obtains the transmitted modified cooking parameter information 142 via the cooking communication unit 305, it interrupts cooking according to the initial cooking parameter information 141 and performs cooking according to the modified cooking parameter information 142.

[0108] In addition, the parameter output unit 1037 may transmit a control signal including the initial cooking parameter information 141 to the cooker 300 in the same manner as the modified cooking parameter information 142 when transmitting the initial cooking parameter information 141. Hereinafter, the transmission or output of the initial cooking parameter information 141 or the modified cooking parameter information 142 is performed in a state where these information are included in the control signal.

[0109] The processing unit 1035 performs processing different from the processing performed by each component other than the processing unit 1035 included in the server control unit 103. For example, the processing unit 1035 transmits the third nutritional information 131d stored in the third storage unit 130 to the operation terminal 200 via the server communication unit 105.

[0110] Figure 6 The diagram shows an example of dish list information 111 , recipe information 112 , basic cooking parameter information 113 , and basic nutritional information 114 .

[0111] For example Figure 6 As shown in (a), the dish list information 111 indicates the dish ID and dish name corresponding to each record number according to the record number. The dish ID is identification information for identifying the dish name and the dish. Specifically, for the record number "1", the dish ID "D001" and the dish name "gravy consomme" are shown in association with each other.

[0112] For example Figure 6 As shown in (b), the recipe information 112 is associated with the dish ID, indicating one or more ingredients used in the dish identified by the dish ID and the respective quantities of the one or more ingredients. Specifically, the recipe information 112 indicates the ingredients corresponding to the record numbers and the quantities of the ingredients according to the record numbers. More specifically, in the recipe information 112 associated with the dish ID "D0001", i.e., the dish name "gravy consomme", for the record number "1", the ingredient "carrot" and the quantity "200g" of the ingredient "carrot" are shown in association with each other.

[0113] For example Figure 6As shown in (c), the basic cooking parameter information 113 is associated with the dish ID, indicating one or more cooking parameters used in the cooker 300 to prepare the dish identified by the dish ID. Each of the one or more cooking parameters includes a cooking parameter name and a set value. Specifically, the basic cooking parameter information 113 indicates the cooking parameter name and the set value corresponding to each record number. More specifically, in the basic cooking parameter information 113 associated with the dish ID "D0001", that is, the dish name "gravy consomme", for the record number "1", the cooking parameter name "temperature" and the set value "100°C" are shown in association with each other. That is, for the record number "1", the temperature "100°C" is shown as the cooking parameter. In addition, the set value may also be expressed as a numerical range such as "90°C to 110°C". In addition, when a numerical value such as "100°C" is shown as the set value, the numerical value may also be an average value or a median value of the set values ​​(for example, temperature) from the start of cooking to the end of cooking in the cooker 300.

[0114] For example Figure 6 As shown in (d), the basic nutritional information 114 is associated with the dish ID, indicating one or more numerical values ​​related to the basic nutrition of the dish represented by the dish ID. Specifically, the one or more numerical values ​​related to nutrition indicate energy and the respective amounts of one or more nutrients. Specifically, the basic nutritional information 114 indicates the nutritional items and amounts corresponding to the record numbers according to each record number. More specifically, in the basic nutritional information 114 associated with the dish ID "D0001", i.e., the dish name "gravy consomme", for the record number "1", the nutritional item "energy" and the amount "200kcal" are shown in association with each other. That is, for the record number "1", the energy "200kcal" is shown as a numerical value related to nutrition. In addition, the amount can also be expressed as a numerical range, such as "180kcal~220kcal", for example.

[0115] Figure 7 The diagram shows an example of image data, chemical analysis data, and weight data included in the cooking status information 121.

[0116] For example Figure 7 As shown in (a) of FIG. 1 , the image data 121a is data showing an image of the food to be cooked placed in the cooking device 300. The image data 121a is obtained by imaging performed by the imaging unit 312 of the cooking device 300.

[0117] For example Figure 7As shown in (b), the chemical analysis data 121b is, for example, data representing a graph obtained using liquid chromatography. The horizontal axis of the graph represents the measurement time, and the vertical axis of the graph represents the count number of components measured at the measurement time. The count number can also be interpreted as intensity. This chemical analysis data 121b is obtained by analysis performed by the chemical analysis unit 313 of the cooking device 300. This graph can be said to represent the respective components of more than one chemical component. The graph can also be called a chromatogram. In addition, the chemical analysis unit 313 may not obtain data representing the graph itself, but instead obtain data directly representing the respective components of several chemical components as the chemical analysis data 121b. That is, the chemical analysis unit 313 may also derive the respective components of a plurality of predetermined chemical components from the graph, and output the chemical analysis data 121b directly representing the components of each of the derived chemical components.

[0118] For example Figure 7 As shown in (c) of FIG. 1 , the weight data 121c is data indicating the weight of the food to be cooked placed in the cooking device 300. The weight data 121c is obtained by measurement performed by the weight measuring unit 311 of the cooking device 300.

[0119] [Screen display]

[0120] Figure 8 2 is a diagram showing an example of a screen display of the operation terminal 200 .

[0121] For example Figure 8 As shown in (a), the terminal control unit 203 of the operation terminal 200 displays the search screen d1 on the display unit 202. The search screen d1 has an input field w1, and the input field w1 is used to accept the input of the dish name. The cook writes the dish name of the dish that the cook wants to make into the input field w1 by performing an input operation on the input unit 201 of the operation terminal 200. For example, the cook writes the dish name "gravy consomme" into the input field w1. As a result, the terminal control unit 203 obtains the input information indicating the dish name "gravy consomme", stores the input information in the terminal storage unit 204, and sends it to the server 100 via the terminal communication unit 205.

[0122] The input acquisition unit 1031 of the server 100 acquires the input information as the dish information from the operation terminal 200 via the server communication unit 105, and stores the dish information in, for example, the server storage unit 104. The processing unit 1035 searches for the dish name "gravy consomme" indicated by the dish information acquired by the input acquisition unit 1031 based on the dish list information 111 stored in the first storage unit 110. When the processing unit 1035 finds the dish name "gravy consomme" based on the dish list information 111, it determines the dish ID associated with the dish name "gravy consomme". Furthermore, the processing unit 1035 acquires the recipe information 112 and the basic nutritional information 114 associated with the dish ID from the first storage unit 110.

[0123] The processing unit 1035 uses the recipe information 112 and the basic nutritional information 114 to generate, for example, Figure 8 The nutrition input screen d2 shown in (b) sends information representing the nutrition input screen d2 to the operation terminal 200 via the server communication unit 105. When the terminal control unit 203 of the operation terminal 200 obtains the information from the server 100 via the terminal communication unit 205, the nutrition input screen d2 represented by the information is displayed on the display unit 202. The nutrition input screen d2 includes a recipe column w2, a basic nutrition column w3, a nutrition adjustment column w4 and a start button b2. In the recipe column w2, one or more ingredients for making the dish "gravy consomme" represented by the recipe information 112 and the respective amounts of the one or more ingredients are displayed. In the basic nutrition column w3, the energy of the dish "gravy consomme" represented by the basic nutrition information 114 and the respective amounts of multiple nutrients contained in the dish "gravy consomme" are displayed.

[0124] In the nutrition adjustment column w4, a plurality of operation buttons b1 for changing the amount of energy and each of the plurality of nutrients displayed in the basic nutrition column w3 are displayed. The cook operates the operation button b1 corresponding to the energy or nutrient that the cook wishes to change among the plurality of operation buttons b1. When receiving input information corresponding to the input operation to the operation button b1, the terminal control unit 203 of the operation terminal 200 changes the amount of energy or nutrient corresponding to the operation button b1.

[0125] For example, when the operation button b1 corresponding to energy is operated, the terminal control unit 203 changes the energy "200kcal" displayed in the basic nutrition column w3 to "-50kcal". That is, the terminal control unit 203 accepts the energy "150kcal" as the energy or energy target desired by the cook. Similarly, when the operation button b1 corresponding to the nutrient "protein" is operated, the terminal control unit 203 changes the protein amount "7g" displayed in the basic nutrition column w3 to "+3g". That is, the terminal control unit 203 accepts the protein amount "10g" as the protein amount or protein target desired by the cook. If there is another nutrient amount that the cook wants to change in addition to the nutrient "protein", the cook repeatedly operates the operation button b1 corresponding to the nutrient. Then, the cook operates the start button b2 displayed on the nutrition input screen d2. When receiving the input operation to the start button b2, the terminal control unit 203 obtains input information indicating the target amount of each of the nutrients "protein", "fat" and "carbohydrate" as the target nutritional information 131a. The terminal control unit 203 transmits the target nutritional information 131a to the server 100 via the terminal communication unit 205.

[0126] In addition, the change range of energy and the change range of nutrient components can also be limited within a predetermined range. In addition, when one adjustment item among energy and the components of multiple nutrients is changed, the remaining other adjustment items can also be changed in conjunction with the change of the one adjustment item. In addition, in the nutrition adjustment column w4, the energy and the components of multiple nutrients shown in the basic nutrition column w3 can be displayed instead of all, and only one of them can be displayed as a changeable adjustment item.

[0127] The nutrition information acquisition unit 1033 of the server 100 acquires the target nutrition information 131a from the operation terminal 200 via the server communication unit 105, and stores the target nutrition information 131a in the third storage unit 130. Moreover, the server control unit 103 derives the initial cooking parameter information 141 using the target nutrition information 131a. Furthermore, the server control unit 103 corrects the initial cooking parameter information 141 to the corrected cooking parameter information 142 by using the cooking state information 121 obtained by the cooking device 300. Furthermore, the server control unit 103 estimates the energy of the dish "gravy consomme" obtained by the cooking device 300 according to the initial cooking parameter information 141 and the corrected cooking parameter information 142 and the amount of each of the plurality of nutrients contained in the dish "gravy consomme". That is, the server control unit 103 derives the third nutrition information 131d as the final nutrition information. Furthermore, the server control unit 103 stores the third nutrition information 131d in the third storage unit 130, and further transmits the third nutrition information 131d to the operation terminal 200 via the server communication unit 105. In addition, the server control unit 103 may also transmit the time correction cooking parameter included in the correction cooking parameter information 142 to the operation terminal 200 via the server communication unit 105.

[0128] The terminal control unit 203 of the operation terminal 200 obtains the third nutrition information 131d and the modified cooking parameters of the time from the server 100 via the terminal communication unit 205. Figure 8 As shown in (c), the terminal control unit 203 displays the final nutrition screen d3 for displaying the third nutrition information 131d, etc. on the display unit 202. The final nutrition screen d3 displays the energy represented by the third nutrition information 131d and the respective amounts of multiple nutrients. Furthermore, in the final nutrition screen d3, the time represented by the above-mentioned modified cooking parameter is displayed as, for example, the cooking completion time "2 hours and 30 minutes".

[0129] The cook can recognize that a dish containing the energy and nutrient amounts according to the target nutrition information 131a will be prepared by checking the energy and nutrient amounts displayed on the final nutrition screen d3 relative to the input of the target nutrition information 131a. Alternatively, the cook can recognize that even if the cook tries to cook so that the energy and nutrient amounts of the dish conform to the target nutrition information 131a, a dish containing energy different from the target nutrition information 131a or a dish containing nutrients of different amounts from the target nutrition information 131a will be prepared. Alternatively, the cook can confirm how close the energy, etc. of the dish finally prepared is to the expectation. In addition, the cook can grasp the time when the cooking of such a dish is completed.

[0130] In addition, when the amount of energy or nutrients is displayed as a numerical range in the basic nutrition column w3, the central value of the numerical range can also be changed, for example, through the operation button b1 of the nutrition adjustment column w4. In this case, the width of the numerical range from the minimum value to the maximum value can also be maintained constant. For example, the energy "180kcal~220kcal" is displayed in the basic nutrition column w3, and the change of "-50kcal" is performed according to the operation of the operation button b1. In this case, the terminal control unit 203 accepts the energy "130kcal~170kcal" as the energy desired by the cook or the energy target. In addition, the initial cooking parameter information 141 and the modified cooking parameter information 142 can also change the central value of the numerical range, for example, so that the energy "180kcal~220kcal" is close to "130kcal~170kcal".

[0131] Fig. 9 It is a diagram showing another example of the screen display of the operation terminal 200 .

[0132] exist Figure 8 In the example shown, the cook directly inputs the name of the dish, but the name of the material (i.e., ingredient) used in the dish can also be input. Fig. 9 As shown in (a), the terminal control unit 203 of the operation terminal 200 displays the ingredient input screen d11 on the display unit 202. The ingredient input screen d11 has an input field w11, which is used to accept the input of the name of the ingredient that the cook wants to use. The cook writes the name of the ingredient that the cook wants to use into the input field w11 by performing an input operation on the input unit 201 of the operation terminal 200. For example, the cook writes the name of the ingredient "carrot" into the input field w11. As a result, the terminal control unit 203 obtains input information indicating the name of the ingredient "carrot", stores the input information in the terminal storage unit 204, and sends it to the server 100 via the terminal communication unit 205.

[0133] The input acquisition unit 1031 of the server 100 acquires the input information from the operation terminal 200 via the server communication unit 105, and stores the input information in, for example, the server storage unit 104. The input acquisition unit 1031 retrieves one or more recipe information 112 indicating the name of the ingredient "carrot" based on the plurality of recipe information 112 stored in the first storage unit 110. Furthermore, the input acquisition unit 1031 determines the dish ID associated with each of the one or more recipe information 112. That is, the input acquisition unit 1031 determines the dish name identified by the dish ID. The input acquisition unit 1031 sends the search result information indicating the determined one or more dish names to the operation terminal 200 via the server communication unit 105.

[0134] When the terminal control unit 203 of the operation terminal 200 obtains the search result information from the server 100 via the terminal communication unit 205, for example, Fig. 9 As shown in (b), the search result screen d12 is displayed on the display unit 202. The search result screen d12 includes a dish name button b11 with the dish name recorded for each of the one or more dishes represented by the search result information. The cook selects the dish name button b11 corresponding to the dish the cook wants to make by performing an input operation on the input unit 201 of the operation terminal 200. For example, the cook selects the dish name button b11 with the dish name "gravy consomme" recorded. As a result, the terminal control unit 203 of the operation terminal 200 obtains the input information indicating the dish name "gravy consomme" written on the selected dish name button b11, stores the input information in the terminal storage unit 204, and sends it to the server 100 via the terminal communication unit 205.

[0135] The input acquisition unit 1031 of the server 100 acquires the input information as the dish information from the operation terminal 200 via the server communication unit 105, and stores the dish information in, for example, the server storage unit 104. The processing unit 1035 searches for the dish name "gravy consomme" indicated by the dish information acquired by the input acquisition unit 1031 based on the dish list information 111 stored in the first storage unit 110. When the processing unit 1035 finds the dish name "gravy consomme" from the dish list information 111, it determines the dish ID associated with the dish name "gravy consomme". Furthermore, the processing unit 1035 acquires the recipe information 112 and the basic nutritional information 114 associated with the dish ID from the first storage unit 110.

[0136] Afterwards, if Fig. 9 As shown in (c) and (d), Figure 8 Similarly to (b) and (c), the operation terminal 200 displays the nutrition input screen d2 and the final nutrition screen d3 on the display unit 202 by communicating with the server 100 .

[0137] This operation terminal 200 is a computer that performs an information providing method for providing information related to the cooking device 300 that cooks the food to be cooked. That is, the operation terminal 200 receives (a) dish information indicating a dish obtained by cooking the food to be cooked and (b) target nutrition information 131a indicating a target with respect to one or more numerical values ​​related to nutrition, based on an operation performed by a user as a cook. Furthermore, the operation terminal 200 outputs final nutrition information indicating one or more numerical values ​​related to nutrition of the dish, which is derived based on the dish information and the target nutrition information 131a, and the nutrition information 131 of the food to be cooked when the cooking device 300 is cooking the food to be cooked, i.e., the nutrition information during cooking. The final nutrition information is the third nutrition information 131d mentioned above. The one or more numerical values ​​related to nutrition are at least one of the numerical values ​​of energy and the respective amounts of one or more nutrients.

[0138] Thus, if the dish information indicating the dish desired by the cook and the target nutrition information 131a desired by the cook are received, one or more numerical values ​​(i.e., energy, etc.) related to the nutrition of the dish finally made based on this information can be prompted to the cook. Therefore, the cook can properly grasp the nutrition of the dish obtained by cooking. In other words, the cook can confirm whether a dish containing the energy desired by the cook can be made, or how close the energy of the dish finally made is to the desired one.

[0139] In addition, in the above example, the input unit 201 of the operation terminal 200 receives text data such as the name of a dish or the name of an ingredient according to the input operation performed by the cook, but it can also receive a voice signal. In this case, the input unit 201 has a microphone and receives the voice signal output from the microphone. And the terminal control unit 203 obtains input information indicating the name of the dish or the name of the ingredient by performing voice recognition on the voice signal.

[0140] [Processing action]

[0141] Fig.10 This is a sequence diagram showing an example of the processing operation of the information processing system 1000 .

[0142] (Step S1)

[0143] First, the operation terminal 200 acquires the dish information and the target nutrition information 131 a based on the input operation performed by the cook on the input unit 201 .

[0144] (Step S2)

[0145] The operation terminal 200 transmits the dish information and the target nutritional information 131 a acquired in step S1 to the server 100 .

[0146] (Step S3)

[0147] When receiving the dish information and target nutritional information 131a transmitted from the operation terminal 200 in step S2, the server 100 uses these information to derive the initial cooking parameter information 141. In deriving the initial cooking parameter information 141, a learning model set 150a corresponding to the dish represented by the dish information is used among the plurality of learning model sets 150a stored in the model storage unit 150. Specifically, the first learning model 151 included in the learning model set 150a is used.

[0148] Fig.17 1 shows an example of the first learning model 151. The input to the first learning model 151 is the target nutrition information 131a. The output from the first learning model 151 is the initial cooking parameter information 141.

[0149] The target nutrition information 131a includes the energy value of the dish represented by the dish information, the protein amount of the dish represented by the dish information, the fat amount of the dish represented by the dish information, and the carbohydrate amount of the dish represented by the dish information. The energy value, the protein amount, the fat amount, and the carbohydrate amount are respectively specified by the user.

[0150] The initial cooking parameter information 141 includes the energy value, protein content, fat content, carbohydrate content, temperature, pressure and time of the cooker to cook the food so that the food represented by the food information has the energy value, protein content, fat content, carbohydrate content, temperature, pressure and time specified by the user. The food may include one or more materials.

[0151] (Step S4)

[0152] The server 100 transmits the derived initial cooking parameter information 141 to the cooker 300 .

[0153] (Step S5)

[0154] When the cooker 300 receives the initial cooking parameter information 141 from the server 100, it starts cooking the food placed in the cooker 300 by controlling the pressure, temperature and time according to the initial cooking parameter information 141. Furthermore, the cooker 300 obtains the cooking state information 121 at time t1. Time t1 is a time point when the first time has passed after the cooker 300 starts cooking. In addition, the first time may be a predetermined time or 0 hours. That is, time t1 may also be a time point when the cooker 300 starts cooking.

[0155] (Step S6)

[0156] The cooking device 300 transmits the cooking state information 121 at the time t1 to the server 100 .

[0157] (Step S7)

[0158] When the server 100 receives the cooking state information 121 at time t1 from the cooking device 300, the server 100 uses the cooking state information 121 to derive the nutritional information 131 of the food being cooked at time t1 as the first nutritional information 131b. In addition, the first nutritional information 131b is the nutritional information during cooking. In addition, in deriving the first nutritional information 131b, the learning model set 150a corresponding to the dish represented by the above-mentioned dish information among the plurality of learning model sets 150a stored in the model storage unit 150 is used. Specifically, the second learning model 152 included in the learning model set 150a is used.

[0159] Fig.18 1 shows an example of the second learning model 152. The input to the second learning model 152 is the cooking state information 121. The output from the second learning model 152 is the nutritional information 131.

[0160] The cooking status information 121 includes image data 121a, chemical analysis data 121b, and weight data 121c.

[0161] The image data 121a may also be an image obtained by the camera 312 at time t of the food being cooked by the cooking device 300 controlled based on the initial cooking parameter information 141 from the cooking start time to time t (for example, refer to Figure 7 (a)) has m×n pixel values. The m×n pixel values ​​can be I(1,1), ~, and I(m,n). I(1,1) is the pixel value of the pixel (1,1) of the image, ~, and I(m,n) is the pixel value of the pixel (m,n) of the image. The pixel (1,1) is located at (x,y)=(1,1) in the image, ~, and the pixel (m,n) is located at (x,y)=(m,n) in the image. m can be an integer greater than 2, and n can be an integer greater than 2. Examples of XY coordinate axes are shown in Figure 7 (a).

[0162] The chemical analysis data 121b may also be a chromatogram obtained by the chemical analysis unit 313 measuring the food cooked by the cooking device 300 controlled based on the initial cooking parameter information 141 from the cooking start time to the time t (for example, refer to Figure 7 The r intensity values ​​in (b)) of . The r intensity values ​​may be the first intensity value at the first measurement time in the chromatogram, , to, the rth intensity value at the rth measurement time in the chromatogram. r may be an integer greater than 1.

[0163] The chemical analysis data 121b may be s components of s chemical components. The s components of s chemical components may be the 1st component of the 1st chemical component, to the sth component of the sth chemical component. s may be an integer greater than 1.

[0164] The weight data 121c may be a weight value measured by the weight measuring unit 311 at time t of the food cooked by the cooking device 300 controlled based on the initial cooking parameter information 141 from the cooking start time to time t.

[0165] The nutritional information 131 includes the energy value, protein content, fat content, and carbohydrate content of the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start time of cooking to time t at time t.

[0166] The above-mentioned time t corresponds to time t1 in step S7. The above-mentioned time t corresponds to time t2 in step S10 described later.

[0167] (Step S8)

[0168] The cooking device 300 acquires the cooking state information 121 at time t2. Time t2 is a time point when a second time has passed after a first time has passed since the cooking device 300 started cooking. The second time may be a predetermined time longer than the first time.

[0169] (Step S9)

[0170] The cooker 300 transmits the cooking state information 121 at the time t2 to the server 100 .

[0171] (Step S10)

[0172] When the server 100 receives the cooking state information 121 at time t2 from the cooking device 300, the server 100 uses the cooking state information 121 to derive the nutritional information 131 of the food to be cooked at time t2 as the second nutritional information 131c. In addition, the second nutritional information 131c is the nutritional information during cooking as well as the first nutritional information 131b. In addition, in deriving the second nutritional information 131c, the learning model set 150a corresponding to the dish represented by the above-mentioned dish information among the plurality of learning model sets 150a stored in the model storage unit 150 is used. Specifically, the second learning model 152 included in the learning model set 150a is used.

[0173] (Step S11)

[0174] The server 100 calculates the difference between the first nutritional information 131b and the second nutritional information 131c. That is, the server 100 calculates the difference between the energy represented by the first nutritional information 131b and the energy represented by the second nutritional information 131c. In addition, the server 100 calculates the difference between the amount of the nutrient represented by the first nutritional information 131b and the amount of the nutrient represented by the second nutritional information 131c for each of the one or more nutrients.

[0175] The above-mentioned "the server 100 calculates the difference between the first nutritional information 131b and the second nutritional information 131c." can also be interpreted as "the server 100 calculates the difference information based on the first nutritional information 131b and the second nutritional information 131c."

[0176] The above difference information can also include

[0177] {(energy contained in the second nutritional information 131c) - (energy contained in the first nutritional information 131b)},

[0178] {(amount of protein contained in the second nutritional information 131c) - (amount of protein contained in the first nutritional information 131b)},

[0179] {(amount of fat contained in the second nutritional information 131c) - (amount of fat contained in the first nutritional information 131b)},

[0180] {(amount of carbohydrates contained in the second nutritional information 131c)-(amount of carbohydrates contained in the first nutritional information 131b)}.

[0181] The above difference information can also include

[0182] {(the energy value of the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start of cooking to the time t2 at the time t2) - (the energy value of the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start of cooking to the time t2 at the time t1)},

[0183] {(the amount of protein in the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start of cooking to the time t2 at the time t2) - (the amount of protein in the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start of cooking to the time t2 at the time t1)},

[0184] {(the amount of fat in the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start of cooking to the time t2 at the time t2) - (the amount of fat in the food cooked by the cooker 300 controlled based on the initial cooking parameter information 141 from the start of cooking to the time t2 at the time t1)},

[0185] {(the amount of carbohydrates of the food cooked by the cooker 300 controlled by the initial cooking parameter information 141 from the start of cooking to time t2 at time t2)-(the amount of carbohydrates of the food cooked by the cooker 300 controlled by the initial cooking parameter information 141 from the start of cooking to time t2 at time t1)}.

[0186] (Step S12)

[0187] Next, the server 100 uses the difference calculated in step S11 to derive the corrected cooking parameter information 142. In deriving the corrected cooking parameter information 142, the learning model set 150a corresponding to the dish represented by the above-mentioned dish information is used among the plurality of learning model sets 150a stored in the model storage unit 150. Specifically, the third learning model 153 included in the learning model set 150a is used.

[0188] Fig.19 1 shows an example of the third learning model 153. The input to the third learning model 152 is the difference information calculated based on the first nutrition information 131b and the second nutrition information 131c, and the target nutrition information 131a. The output from the third learning model 153 is the corrected cooking parameter information 142.

[0189] The modified cooking parameter information 142 includes the temperature, pressure, and time for cooking the food cooked by the cooker 300 controlled by the initial cooking parameter information 141 from the start time of cooking to the time t3 so that the dish represented by the dish information has the energy value, protein amount, fat amount, carbohydrate amount, etc. specified by the user as shown in the target nutritional information 131a.

[0190] Time t4 may be later than time t3 or the same as time t3. Time t3 may be later than time t1 and time t2. Time t1 and time t2 may be later than the cooking start time.

[0191] (Step S13)

[0192] Then, the server 100 transmits the corrected cooking parameter information 142 derived in step S12 to the cooker 300 .

[0193] (Step S14)

[0194] The cooker 300 receives the revised cooking parameter information 142 transmitted in step S13 and changes the initial cooking parameter information 141 to the revised cooking parameter information 142. That is, the cooker 300 interrupts cooking according to the initial cooking parameter information 141 and starts cooking according to the revised cooking parameter information 142.

[0195] (Step S15)

[0196] The server 100 further uses the modified cooking parameter information 142 derived in step S12 to derive the final nutritional information 131 of the dish represented by the above-mentioned dish information when it is cooked as the third nutritional information 131d. In other words, the third nutritional information 131d is estimated. In deriving the third nutritional information 131d, a learning model set 150a corresponding to the dish represented by the above-mentioned dish information is used among the plurality of learning model sets 150a stored in the model storage unit 150. Specifically, the fourth learning model 154 included in the learning model set 150a is used.

[0197] Fig. 20 14 shows an example of the fourth learning model 154. The input to the fourth learning model 154 is the modified cooking parameter information 142 and the nutritional status during cooking. The output from the fourth learning model 153 is the nutritional information of the prepared dish (i.e., the third nutritional information 131d). The third nutritional information 131d includes the energy value, protein content, fat content, and carbohydrate content of the prepared dish.

[0198] (Step S16)

[0199] The server 100 transmits the corrected cooking parameters of the time included in the corrected cooking parameter information 142 derived in step S12 and the third nutrition information 131d derived in step S15 to the operation terminal 200. Alternatively, the server 100 may transmit all the corrected cooking parameters included in the corrected cooking parameter information 142.

[0200] (Step S17)

[0201] The operation terminal 200 receives the modified cooking parameter of the time included in the modified cooking parameter information 142 sent in step S16 and the third nutritional information 131d. Figure 8 (c) or Fig. 9 As shown in (d) of FIG. 1 , the operation terminal 200 displays the corrected cooking parameter of the time and the third nutritional information 131d on the display unit 202. The corrected cooking parameter of the time is displayed as, for example, the cooking completion time.

[0202] Thus, in this embodiment, the dish information indicating the dish desired by the cook and the target nutritional information 131a desired by the cook are obtained, and the initial cooking parameter information 141 is obtained based on them. Then, by sending the initial cooking parameter information 141 to the cooker 300, the cooker 300 starts cooking according to the initial cooking parameter information 141. Thereafter, the initial cooking parameter information 141 used by the cooker 300 is corrected according to one or more numerical values ​​(i.e., energy, etc.) related to the nutrition of the food being cooked during cooking. Therefore, by cooking according to the corrected cooking parameter information 142, the energy, etc. of the dish finally prepared can be made close to the energy, etc. indicated by the target nutritional information 131a. In other words, the energy, etc. of the dish finally prepared can be made close to the energy, etc. desired by the cook. That is, even if the energy, etc. desired by the cook is different from the energy, etc. described in the basic recipe, or even if the amount of the food being cooked is not as in the recipe, the energy, etc. of the dish finally prepared can be made close to the energy, etc. desired by the cook. As a result, the nutrition of the dish can be appropriately controlled without the cook intentionally adjusting the cooking parameters.

[0203] Fig.11 This is a flowchart showing an example of the processing operation of the server 100 .

[0204] (Step S110)

[0205] First, the input acquisition unit 1031 of the server 100 acquires the dish information and the target nutrition information 131 a from the operation terminal 200 via the server communication unit 105 .

[0206] (Step S120)

[0207] The parameter acquisition unit 1032 derives the initial cooking parameter information 141 using the dish information and the target nutrition information 131 a .

[0208] (Step S130)

[0209] The parameter output unit 1037 transmits the initial cooking parameter information 141 acquired in step S120 to the cooking device 300 via the server communication unit 105 .

[0210] (Step S140)

[0211] The processing unit 1035 obtains the cooking status information 121 from the cooking device 300 via the server communication unit 105 , and stores the cooking status information 121 in the second storage unit 120 .

[0212] (Step S150)

[0213] The nutrition information acquisition unit 1033 derives the nutrition information during cooking using the cooking status information 121 acquired in step S140.

[0214] (Step S160)

[0215] After performing the processing of step S150, the parameter correction unit 1034 determines whether a plurality of nutrition information during cooking has been derived. That is, the parameter correction unit 1034 determines whether the first nutrition information 131b and the second nutrition information 131c have been derived. Here, when it is determined in the processing of step S160 that a plurality of nutrition information during cooking has not been derived (step S160: No), the processing unit 1035 and the nutrition information acquisition unit 1033 repeatedly perform the processing of step S140 and step S150. That is, the nutrition information acquisition unit 1033 acquires the first nutrition information 131b and the second nutrition information 131c by repeatedly performing the processing of step S150. Specifically, the nutrition information acquisition unit 1033 acquires the nutrition information during cooking at a time point after a first time has passed since the cooking device 300 started cooking as the first nutrition information 131b. Furthermore, the nutrition information acquisition unit 1033 acquires the nutrition information during cooking at a time point after a second time has passed since the cooking device 300 started cooking as the second nutrition information 131c. Fig.10 At time t1, the time point after the second time is equivalent to Fig.10 moment t2.

[0216] (Step S170)

[0217] On the other hand, when the parameter correction unit 1034 determines that a plurality of nutrition information during cooking is derived in the process of step S160 (step S160: Yes), the parameter correction unit 1034 calculates the difference between the nutrition information during cooking. In other words, the parameter correction unit 1034 calculates the difference between the first nutrition information 131b and the second nutrition information 131c.

[0218] (Step S180)

[0219] Then, the parameter correction unit 1034 uses the target nutrition information 131a obtained in step S110 and the difference calculated in step S170 to derive the corrected cooking parameter information 142. In addition, the corrected cooking parameter information 142 is information for making one or more numerical values ​​related to the nutrition of the final dish closer to one or more numerical values ​​represented by the target nutrition information 131a. In this way, the parameter correction unit 1034 in this embodiment changes the initial cooking parameter information 141 to the corrected cooking parameter information 142 based on the difference between the first nutrition information 131b and the second nutrition information 131c and the target nutrition information 131a.

[0220] Thus, in this embodiment, based on the amount of change in the nutritional information during cooking and the target nutritional information 131a, the initial cooking parameter information 141 is corrected to the corrected cooking parameter information 142. Therefore, by considering the change tendency of energy, etc. caused by cooking according to the initial cooking parameter information 141, the energy, etc. of the final dish can be effectively made close to the energy, etc. desired by the cook.

[0221] (Step S190)

[0222] The parameter output unit 1037 transmits the corrected cooking parameter information 142 derived in step S180 to the operation terminal 200 and the cooking device 300 via the server communication unit 105. The parameter output unit 1037 may transmit only the corrected cooking parameter for the time included in the corrected cooking parameter information 142 to the operation terminal 200.

[0223] (Step S200)

[0224] The nutrition information acquisition unit 1033 uses the modified cooking parameter information 142 derived in step S180 to derive the third nutrition information 131d. That is, based on the modified cooking parameter information 142, the nutrition information acquisition unit 1033 acquires the third nutrition information 131d indicating one or more numerical values ​​related to the nutrition of the dish obtained by cooking with the cooking device 300 according to the modified cooking parameter information 142.

[0225] (Step S210)

[0226] The parameter output unit 1037 transmits the third nutritional information 131d derived in step S200 to the operation terminal 200 via the server communication unit 105. The third nutritional information 131d is displayed on the display unit 202 of the operation terminal 200.

[0227] Thus, in this embodiment, information indicating the energy of the final dish is estimated as the third nutritional information 131d. And the third nutritional information 131d is presented to the cook. As a result, the cook can confirm whether the dish containing the energy desired by the cook can be prepared, or how close the energy of the final dish is to the desired one.

[0228] Fig.12 Detailed description of a part of the processing operation of the server 100. Fig.12 (a) means Fig.11 The flowchart of the detailed processing of step S120 is as follows, Fig.12 (b) means Fig.11 Flowchart of the detailed processing of step S150. Fig.12 (c) means Fig.11 A flowchart of the detailed processing of step S180 is shown in FIG. Fig.12 (d) means Fig.11 Flowchart of the detailed processing of step S200.

[0229] When the parameter acquisition unit 1032 derives the initial cooking parameter information 141, for example, Fig.12 The processing of steps S121 to S123 shown in (a).

[0230] (Step S121)

[0231] The parameter acquisition unit 1032 reads the first learning model 151 corresponding to the menu information from the model storage unit 150. That is, the parameter acquisition unit 1032 reads the first learning model 151 included in the learning model set 150a corresponding to the menu name indicated by the menu information from the model storage unit 150.

[0232] (Step S122)

[0233] The parameter acquisition unit 1032 inputs the target nutritional information 131 a to the first learning model 151 read out in step S121 .

[0234] (Step S123)

[0235] The parameter acquisition unit 1032 acquires the initial cooking parameter information 141 output from the first learning model 151 by the input in step S122. The initial cooking parameter information 141 is derived in this way.

[0236] When the nutrition information acquisition unit 1033 derives the nutrition information during cooking, such as the first nutrition information 131b, for example, Fig.12 The processing of steps S151 to S153 shown in (b).

[0237] (Step S151)

[0238] The nutrition information acquisition unit 1033 reads the second learning model 152 corresponding to the menu information from the model storage unit 150. That is, the nutrition information acquisition unit 1033 reads the second learning model 152 included in the learning model set 150a corresponding to the menu name indicated by the menu information from the model storage unit 150.

[0239] (Step S152)

[0240] The nutrition information acquisition unit 1033 inputs the latest cooking status information 121 into the read second learning model 152 .

[0241] (Step S153)

[0242] The nutrition information acquisition unit 1033 acquires the nutrition information 131 output from the second learning model 152 as the nutrition information during cooking, thereby deriving the nutrition information during cooking.

[0243] In this way, the nutrition information acquisition unit 1033 in this embodiment acquires nutrition information during cooking by inputting an image of the food being cooked, the weight of the food being cooked, and the amount of chemical components contained in the food being cooked into the second learning model 152. Thus, since the second learning model 152 is used to acquire nutrition information during cooking, nutrition information during cooking with high accuracy can be acquired.

[0244] In addition, the image of the food to be cooked, the weight of the food to be cooked, and the amount of chemical components contained in the food to be cooked are included in the cooking state information 121 as image data 121a, weight data 121c, and chemical analysis data 121b, respectively. In addition, in the present embodiment, the image data 121a, weight data 121c, and chemical analysis data 121b are input to the second learning model 152, but only one of the image data 121a, chemical analysis data 121b, and weight data 121c, or only two of the image data 121a, chemical analysis data 121b, and weight data 121c may be input to the second learning model 152. In other words, at least one of the image data 121a, weight data 121c, and chemical analysis data 121b may be input to the second learning model 152. Even in this case, it is possible to obtain highly accurate nutritional information during cooking.

[0245] When the parameter correction unit 1034 derives the corrected cooking parameter information 142, for example, Fig.12 The processing of steps S181 to S184 shown in (c).

[0246] (Step S181)

[0247] The parameter correction unit 1034 reads the third learning model 153 corresponding to the menu information from the model storage unit 150. That is, the parameter correction unit 1034 reads the third learning model 153 included in the learning model set 150a corresponding to the menu name indicated by the menu information from the model storage unit 150.

[0248] (Step S182)

[0249] The parameter correction unit 1034 inputs the difference in the nutrition information during cooking and the target nutrition information 131 a to the read third learning model 153 .

[0250] (Step S183)

[0251] The parameter correction unit 1034 acquires a plurality of candidates outputted from the third learning model 153 by the input in step S182 . The plurality of candidates are candidates for correcting the cooking parameter information 142 .

[0252] (Step S184)

[0253] The parameter correction unit 1034 selects the candidate closest to the initial cooking parameter information 141 from among the plurality of candidates acquired in step S183 as the corrected cooking parameter information 142. Thus, the corrected cooking parameter information 142 is derived.

[0254] In this way, the parameter correction unit 1034 in this embodiment obtains multiple candidates for the modified cooking parameter information 142 based on the target nutrition information 131a and the nutrition information during cooking. Moreover, the parameter correction unit 1034 selects the candidate closest to the initial cooking parameter information 141 from the multiple candidates as the modified cooking parameter information 142. Alternatively, the parameter correction unit 1034 may also select a candidate whose difference from the initial cooking parameter information 141 is below a threshold value from the multiple candidates as the modified cooking parameter information 142. For example, the multiple candidates are respectively represented as vectors including pressure cooking parameters, temperature cooking parameters, and time cooking parameters. Similarly, the initial cooking parameter information 141 is also represented as a vector including pressure cooking parameters, temperature cooking parameters, and time cooking parameters. Therefore, the parameter correction unit 1034 may also calculate the distance between the vectors of the multiple candidates and the vector of the initial cooking parameter information 141, and select the candidate whose distance is below the threshold value or is the smallest from the multiple candidates as the modified cooking parameter information 142. In addition, among the multiple candidates, for example, one or two predetermined cooking parameters are the same as the initial cooking parameter information 141 and only the remaining two or one cooking parameter is different from the initial cooking parameter information 141, and the candidate may be selected as the corrected cooking parameter information 142. The predetermined one or two cooking parameters may also be a temperature cooking parameter, a pressure cooking parameter, or the like.

[0255] Thus, even when a plurality of candidates are output from the third learning model 153, a candidate that is not much different from the initial cooking parameter information 141 is adopted as the corrected cooking parameter information 142. Therefore, it is possible to reduce the processing load of the cooking device 300 associated with the correction of the initial cooking parameter information 141. In addition, it is possible to suppress a significant change in the taste of the dish.

[0256] When the nutrition information acquisition unit 1033 derives the third nutrition information 131d, for example, Fig.12 The processing of steps S201 to S203 shown in (d).

[0257] (Step S201)

[0258] The nutrition information acquisition unit 1033 reads the fourth learning model 154 corresponding to the menu information from the model storage unit 150. That is, the nutrition information acquisition unit 1033 reads the fourth learning model 154 included in the learning model set 150a corresponding to the menu name indicated by the menu information from the model storage unit 150.

[0259] (Step S202)

[0260] The nutrition information acquisition unit 1033 inputs the second nutrition information 131 c and the corrected cooking parameter information 142 to the read fourth learning model 154 .

[0261] (Step S203)

[0262] The nutritional information acquisition unit 1033 acquires the nutritional information 131 output from the fourth learning model 154 as the third nutritional information 131d by the input in step S202. Thus, the third nutritional information 131d is derived.

[0263] In this way, the nutrition information acquisition unit 1033 in the present embodiment acquires the third nutrition information 131 d by inputting at least the corrected cooking parameter information 142 into the fourth learning model 154 .

[0264] [Example of building a learning model]

[0265] Fig.13 This is a flowchart showing an example of constructing the first learning model 151 .

[0266] (Step S301)

[0267] First, the model maker generates a plurality of types of cooking parameter information for a predetermined dish. The cooking parameter information indicates one or more cooking parameters used by the cooking unit 320 of the cooker 300.

[0268] (Step S302)

[0269] Next, the model maker creates a sample of a dish (also referred to as a dish sample) for each of the plurality of cooking parameter information by cooking according to the cooking parameter information by the cooker 300. The cooker 300 cooks one or more ingredients shown in the recipe information corresponding to the predetermined dish.

[0270] (Step S303)

[0271] The model maker measures the nutritional status of each dish sample created in step S302. The nutritional status includes energy and the amount of each nutrient contained in the dish sample.

[0272] (Step S304)

[0273] The model maker selects a machine learning algorithm for constructing the first learning model 151 for the above-mentioned predetermined dish.

[0274] (Step S305)

[0275] The model maker enables the learning model to learn the relationship between the nutritional status and cooking parameter information associated with the above-mentioned predetermined dish according to the machine learning algorithm selected in step S304.

[0276] (Step S306)

[0277] The model maker verifies the learning model that has been learned through the process of step S305. That is, the model maker verifies whether the correct cooking parameter information is output from the learning model as the initial cooking parameter information 141 for the input of the nutritional information representing the nutritional status to the learning model. The learning model that has been verified to have output the correct cooking parameter information is stored in the model storage unit 150 of the server 100 as the first learning model 151 corresponding to the predetermined dish. In addition, the correct cooking parameter information refers to information that a dish of the nutritional status input to the learning model can actually be made by cooking according to the cooking parameter information.

[0278] Fig.14 This is a flowchart showing an example of constructing the second learning model 152 .

[0279] (Step S311)

[0280] First, the model maker generates multiple types of recipe information for a predetermined dish. In addition, the recipe information indicates more than one material used in the predetermined dish and the respective quantities of the more than one material.

[0281] (Step S312)

[0282] Next, the model maker creates a dish sample for each of the multiple types of recipe information by cooking according to the recipe information using the cooking device 300. The dish sample may also be a sample at a time point after the first time or the second time has passed since the start of cooking.

[0283] (Step S313)

[0284] The model maker determines the cooking state of each dish sample created in step S312. That is, the model maker obtains image data by photographing the dish sample using a camera, obtains chemical analysis data by analyzing the dish sample using a chemical analysis device, and obtains weight data of the dish sample using a weighing instrument. Thus, the image data, chemical analysis data, and weight data are determined as the cooking state of the dish sample.

[0285] (Step S314)

[0286] The model maker measures the nutritional status of each dish sample created in step S312, that is, the energy and the amount of each nutrient contained in the dish sample.

[0287] (Step S315)

[0288] The model maker selects a machine learning algorithm for constructing the second learning model 152 for the above-mentioned predetermined dish.

[0289] (Step S316)

[0290] The model maker enables the learning model to learn the relationship between the cooking state and the nutritional state according to the machine learning algorithm selected in step S315.

[0291] (Step S317)

[0292] The model maker verifies the learning model that has been learned through the process of step S316. That is, the model maker verifies whether the input of the cooking state information representing the cooking state to the learning model outputs the nutrition information representing the correct nutrition state from the learning model. The learning model that has been verified to output the nutrition information representing the correct nutrition state is stored in the model storage unit 150 of the server 100 as the second learning model 152 corresponding to the predetermined dish. In addition, the correct nutrition state refers to the actual nutrition state of the dish sample of the cooking state input to the learning model.

[0293] In this way, the second learning model 152 in this embodiment is machine-learned to output one or more numerical values ​​related to the nutrition of the one or more ingredients, for the input of the image of one or more ingredients, the weight of one or more ingredients, and the amount of chemical components contained in one or more ingredients being cooked in the cooking device 300. In addition, the one or more numerical values ​​related to the nutrition of the one or more ingredients are equivalent to the above-mentioned nutritional status or nutritional information 131. In addition, the image, weight, and amount of chemical components of the one or more ingredients are respectively equivalent to the above-mentioned image data 121a, weight data 121c, and chemical analysis data 121b, which represent the cooking status of the above-mentioned dish sample. In addition, in the machine learning in this embodiment, the image, weight, and amount of chemical components are input into the learning model, but only one of the image, weight, and amount of chemical components, or only two of the image, weight, and amount of chemical components can be input into the learning model. That is, the second learning model 152 can also be machine-learned to output nutritional information representing the nutritional status of the one or more ingredients, for the input of at least one of the image, weight, and amount of chemical components of the one or more ingredients.

[0294] Therefore, when at least one of the image data 121a, weight data 121c and chemical analysis data 121b of the cooked food is input into the second learning model 152 by the nutritional information acquisition unit 1033, highly accurate nutritional information during cooking can be acquired from the second learning model 152.

[0295] Fig.15 This is a flowchart showing an example of constructing the third learning model 153 .

[0296] (Step S321)

[0297] First, the model maker generates cooking parameter information for a predetermined dish in various ways.

[0298] (Step S322)

[0299] Next, the model maker starts cooking the dish sample using the cooker 300 according to the cooking parameter information for each of the multiple types of cooking parameter information.

[0300] (Step S323)

[0301] After the model maker starts cooking in step S322, the model maker measures the nutritional status of each dish sample at two time points. Moreover, the model maker calculates the difference information based on the nutritional status measured at the two time points. In addition, the two time points are the time points when the cooking device 300 is cooking. In other words, the measured nutritional status is the nutritional status during cooking. In addition, the two time points can also be the time point after the first time and the time point after the second time mentioned above.

[0302] (Step S324)

[0303] Then, the model maker modifies the cooking parameter information in a variety of ways during cooking. That is, the model maker interrupts cooking according to the cooking parameter information before modification and starts cooking according to the modified cooking parameter information.

[0304] (Step S325)

[0305] The model maker measures the nutritional status of each dish sample made according to the corrected cooking parameter information, that is, the energy and the amount of each nutrient contained in the dish sample. The nutritional status measured at this time is the final nutritional status after cooking.

[0306] (Step S326)

[0307] The model maker selects a machine learning algorithm for constructing the third learning model 153 for the above-mentioned predetermined dish.

[0308] (Step S327)

[0309] The model maker causes the learning model to learn the relationship between the difference in the nutritional status during cooking calculated in step S323 and the final nutritional status measured in step S325 and the corrected cooking parameter information according to the machine learning algorithm selected in step S326.

[0310] (Step S328)

[0311] The model maker verifies the learning model that has been learned through the process of step S327. That is, the model maker verifies whether the correct corrected cooking parameter information is output from the learning model as the corrected cooking parameter information 142 for the difference in the nutritional state during cooking and the nutritional information representing the final nutritional state. The learning model that is verified to have output the correct corrected cooking parameter information is stored in the model storage unit 150 of the server 100 as the third learning model 153. In addition, the above-mentioned final nutritional state is equivalent to the target nutritional information 131a. In addition, the correct corrected cooking parameter information refers to the information actually required to prepare a dish of the final nutritional state input to the learning model when the nutritional state changes, such as the difference in the nutritional state input to the learning model. Through the learning model constructed in this way, that is, the third learning model 153, it is possible to obtain the corrected cooking parameter information 142 that makes the nutritional state during cooking close to the target nutritional information 131a.

[0312] Fig.16 This is a flowchart showing an example of constructing the fourth learning model 154 .

[0313] (Step S331)

[0314] First, the model maker generates cooking parameter information for a predetermined dish in various ways.

[0315] (Step S332)

[0316] Next, the model maker starts cooking the dish sample using the cooker 300 according to the cooking parameter information for each of the multiple types of cooking parameter information.

[0317] (Step S333)

[0318] Then, after the model maker starts cooking in step S332, the model maker measures the nutritional status of each dish sample. The nutritional status measured at this time is the nutritional status during cooking. Furthermore, the model maker corrects the cooking parameter information in a variety of ways during cooking. That is, the model maker interrupts cooking according to the cooking parameter information before correction and starts cooking according to the cooking parameter information after correction. In addition, the processing of step S333 can also be performed at a time point after the above-mentioned second time has passed since the start of cooking. The processing of step S333 can also be started from a time point after the above-mentioned second time has passed since the start of cooking.

[0319] (Step S334)

[0320] The model maker measures the nutritional status of each dish sample made according to the corrected cooking parameter information, that is, the energy and the amount of each nutrient contained in the dish sample. The nutritional status measured at this time is the final nutritional status after cooking.

[0321] (Step S335)

[0322] The model maker selects a machine learning algorithm for constructing the fourth learning model 154 for the above-mentioned predetermined dish.

[0323] (Step S336)

[0324] The model maker causes the learning model to learn the relationship between the final nutritional status measured in step S334, the nutritional status during cooking measured in step S333, and the corrected cooking parameter information according to the machine learning algorithm selected in step S335.

[0325] (Step S337)

[0326] The model maker verifies the learning model that has been learned through the process of step S336. That is, the model maker verifies whether the correct final nutritional state is output from the learning model as the third nutritional information 131d for the nutritional information representing the nutritional state during cooking and the corrected cooking parameter information input to the learning model. The learning model that has been verified to output the nutritional information representing the correct final nutritional state is stored in the model storage unit 150 of the server 100 as the fourth learning model 154. In addition, the correct final nutritional state refers to the actual nutritional state of the final dish sample obtained by cooking the dish sample of the nutritional state during cooking input to the learning model according to the corrected cooking parameter information input to the learning model.

[0327] In this way, the fourth learning model 154 in the present embodiment is machine-learned to output one or more numerical values ​​related to the nutrition of a dish obtained by cooking the dish according to the one or more cooking parameters by the cooker 300, at least for the input of one or more cooking parameters changed during the cooking process of the cooker 300. In addition, the one or more cooking parameters after correction correspond to the corrected cooking parameter information 142, and the one or more numerical values ​​related to the nutrition of the dish are information indicating the final nutritional status of the dish, which correspond to the third nutritional information 131d.

[0328] Since the fourth learning model 154 obtained by such machine learning is used to obtain the third nutritional information 131d, the third nutritional information 131d with high accuracy can be obtained.

[0329] As described above, in the information processing system 1000 of the present embodiment, the nutrition of the dish can be properly controlled without the cook intentionally adjusting the cooking parameters. In addition, the cook can properly grasp the nutrition of the dish obtained by cooking. In other words, the cook can confirm whether the dish containing the energy desired by the cook can be made, or how close the energy of the dish finally made is to the desired one.

[0331] The above describes the information processing system, server, operation terminal, etc. involved in the present disclosure based on the implementation mode, but the present disclosure is not limited to the implementation mode. As long as it does not depart from the main purpose of the present disclosure, the various deformations that a person skilled in the art can think of to the implementation mode are also included in the scope of the present disclosure.

[0332] For example, the operation terminal 200 in the above embodiment is a device independent of the cooker 300, but it can also be assembled in the cooker 300.

[0335] In addition, the server 100 in the above embodiment obtains the cooking parameter information including one or more cooking parameters for cooking by the cooking device 300 based on the dish information and the target nutritional information 131a. That is, the server 100 obtains the initial cooking parameter information 141. However, the server 100 may not obtain the initial cooking parameter information 141. In this case, the server 100 obtains the nutritional information of the food being cooked when the cooking device 300 cooks the food according to the basic cooking parameter information 113.

Here, the one or more nutrition-related values ​​are at least one of energy and the respective amounts of one or more nutrients. In addition, the cooking parameter information is the basic cooking parameter information 113 or the initial cooking parameter information 141, which can be obtained from the cooking device 300. In addition, the control signal may be output or transmitted to the cooking device 300. This control method can also achieve the same effects as the control method in the above embodiment.
