<1. First Embodiment>
<1-1. Configuration of nutrient analysis system>
FIG. 1 is a schematic diagram showing the configuration of a nutrient analysis system 1 according to the first embodiment of the present invention. FIG. 2 is a block diagram showing functions of the nutrient analysis system 1. 3 to 5 are examples of the meal photo data S25 with a scale.

  This nutrient analysis system 1 is a system that analyzes ingested nutrients by inputting the contents of each meal of the user. As shown in FIG. 1, the nutrient analysis system 1 includes a user terminal 2 and a center computer 3 that is an analysis system.

  As shown in FIG. 1, a smart phone 2a or a tablet terminal 2b is used as the user terminal 2. As the user terminal 2, a user terminal group 2c including a personal computer, a digital camera, and a communication interface may be used. Below, the case where the smart phone 2a is used as the user terminal 2 is demonstrated.

  The smart phone 2a is an example of the user terminal 2 for transmitting the scale-equipped meal photo data S25 to the center computer 3. The smart phone 2a includes a first control unit 21, a first storage unit 22, a first display unit 23, a first input unit 24, an image acquisition unit 25, and a first communication unit 26.

  The 1st control part 21 is a control part which controls operation of each part of smart phone 2a. The first control unit 21 is realized by a CPU or the like, for example. The first storage unit 22 stores data input from the first control unit 21. The first storage unit 22 is realized by a readable / writable storage medium such as a hard disk memory or an SD card. The first control unit 21 controls the operation of each unit in the smart phone 2 a while referring to the computer program and various data stored in the first storage unit 22 and the command input from the input unit 24.

  The first display unit 23 and the first input unit 24 of the present embodiment are realized by the touch panel display 20. Therefore, the touch panel display 20 as the first display unit 23 displays various images such as a meal photo data S25 with scale and an information input screen described later. The touch panel display 20 as the first input unit 24 is an information input unit for a user to input information to the first control unit 21.

  The image acquisition unit 25 of the smart phone 2a is an imaging unit that captures meals and acquires image data S251. The image acquisition unit 25 of the present embodiment is realized by a camera provided in advance on the smart phone 2a. The image acquisition unit 25 is realized by, for example, a camera having an optical system including a lens 251 and a focus adjustment mechanism 252 and an image sensor 253 such as a CCD or a CMOS.

  The image data acquired by the image acquisition unit 25 is digitized by an A / D conversion unit (not shown) in the smart phone 2a. When shooting is performed by the image acquisition unit 25, first, the digitized image data input from the image sensor 253 is displayed on the first display unit 23. Then, the user performs composition, focus adjustment, and the like while confirming the image displayed on the first display unit 23. Thereafter, when the user inputs a shooting command to the first input unit 24, the first control unit 21 stores the image data in the first storage unit 22.

  In this embodiment, the 1st control part 21 and the image acquisition part 25 have a function which produces scale data automatically at the time of imaging of a meal. When a meal is photographed by the image acquisition unit 25, first, the user automatically or manually focuses on the meal while checking the image data acquired by the image sensor 253 and displayed on the first display unit 23. At this time, the first control unit 21 estimates the distance between the lens 251 and the meal based on the operation of the focus adjustment mechanism 252 and creates scale data for the image data displayed on the first display unit 23. And if a user inputs a photography command to the 1st input part 24, the 1st control part 21 will combine meal photo data which is the image data which photoed the meal, and scale data, and meal photo data with a scale. The data is stored in the first storage unit 22 via the first control unit 21 as S25.

  Thus, in this embodiment, scale data is automatically given to meal photo data at the time of imaging. 3 and 4 show an example of meal photo data S25 with scale when scale data is automatically given.

  In the example of FIG. 3, an x-axis and a y-axis that are parallel to the placement surface on which the meal is placed and are orthogonal to each other and a z-axis that is orthogonal to the x-axis and the y-axis so that a three-dimensional sense of distance can be grasped. Is displayed in the vicinity of the meal image. Further, in the example of FIG. 4, the scale rule 42 based on the placement surface on which the meal is placed is displayed around the meal image. The scale data is not necessarily displayed visually in the meal photo data with scale S25. The scale data may hold a sense of distance at each coordinate of the meal photograph data obtained by taking a meal as data such as parameters that are not visually displayed.

  In the present invention, the scale data may not be automatically acquired by the first control unit 21 and the image acquisition unit 25. 5 and 6, imaging is performed by the image acquisition unit 25 in a state in which a scale member 40 that can be scaled by imaging together with a meal is arranged in the vicinity of the meal. Thereby, the image data imaged with the scale member 4 becomes the meal photo data S25 with a scale.

  In the example of FIG. 5, a meal is photographed together with a scale cube 43 that is a scale member 40 having a cube shape of a predetermined size in order to grasp a three-dimensional sense of distance. The lower surface of the scale cube 43 contacts the placement surface on which the meal is placed. Thereby, the two sides forming the upper surface of the scale cube 43 become the scale axes indicating the x-axis and the y-axis that are parallel to the placement surface and orthogonal to each other. Further, the side connecting the upper surface corner and the lower surface corner of the scale cube 43 becomes the scale axis indicating the z axis orthogonal to the x axis and the y axis.

  In the example of FIG. 6, a meal is photographed together with a scale mat 44 that is a scale member 40 having a grid pattern with a predetermined interval. The lattice-like pattern of the scale mat 44 becomes a scale axis indicating the x axis and the y axis perpendicular to each other along the placement surface on which the meal is placed. Further, in the lattice pattern, since the shooting angle with respect to the placement surface can be estimated from the angle between the adjacent line segments, the scale axis in the z-axis direction can be estimated.

  In addition to the scale cube 43 and the scale mat 44, tableware having a depth such as a tea bowl or a soup bowl may be used as the scale member 40. In that case, it is necessary to register in advance parameters indicating the scale such as the diameter and height of the tableware used as the scale member 4.

  The first communication unit 26 transmits / receives data to / from the center computer 3 via the Internet 100. The first communication unit 26 transmits the meal photo data with scale S25, the explanation data S24 described later, and the like to the center computer 3. In addition, the first communication unit 26 receives food data S322, nutrient data S323, deficient nutrient data S323, recommended food data S325, and the like transmitted from the center computer 3.

  As shown in FIGS. 1 and 2, the center computer 3 is an analysis system for analyzing meal contents received via the Internet 100 from a smartphone 2 a that is a user side terminal. The center computer 3 includes a second communication unit 31, a second control unit 32, a second storage unit 33, a second display unit 34, and a second input unit 35.

  The second communication unit 31 is a communication device for performing transmission / reception of data between the second control unit 32 and the smart phone 2 a via the Internet 100. The second communication unit 31 receives the meal photo data with scale S25, the explanation data S24, and the like from the smart phone 2a via the Internet 100. In addition, the second communication unit 31 transmits the food data S322, the nutrient data S323, the deficient nutrient data S324, the recommended food data S326, and the like to the first communication unit 26.

  As shown in FIG. 2, the second control unit 32 is configured by a CPU, for example. Moreover, the 2nd memory | storage part 33 is comprised by memory, for example. The second control unit 32 and the second storage unit 33 of the present embodiment are configured by the personal computer 30.

  As the second display unit 34, for example, a display for a personal computer is used. For example, a keyboard or a mouse for a personal computer is used for the second input unit 35. By operating the second input unit 35 while visually recognizing the second display unit 34, the operator advances each process on the center computer 3 side.

  The second control unit 32 refers to the computer program P2 and the data D2 stored in the second storage unit 33 and the command input from the second input unit 35, while the second communication unit 31 and the second display unit 34 Control each action. In addition, the second control unit 32 includes a quantity estimation unit 321 realized on software, a food data creation unit 322, a nutrient calculation unit 323, a deficient nutrient calculation unit 324, and a food proposal unit 325.

  Based on the scaled meal photo data S25, the serving amount estimation unit 321 calculates estimated data S321 in which the volume of the dish described in the scaled meal photo data S25 is estimated for each dish while referring to the scale data. After the estimation data S321 is calculated, the operator operates the second input unit 35 to input the meal content data S35 such as the material name and the ratio of each material for each dish based on the explanation data S24 and the like. The estimated data S321 and the meal content data S35 are transmitted to the food material data creation unit 322.

  The food material data creation unit 322 creates food material data S322 based on the estimated data S321 and the meal content data S35. Specifically, the ingredient data S322 represents the ingredient name and weight of each ingredient with respect to the dishes shown in the meal photo data with scale S25.

  Based on the food material data S322, the nutrient calculation unit 323 calculates the nutrients included in the dish shown in the scaled meal photo data S25 as the nutrient data S323. That is, the nutrient calculation unit 323 calculates the nutrient data S323 corresponding to the scaled meal photo data S25.

  The nutrient calculation unit 323 of this embodiment refers to the data table stored in the second storage unit 33 when calculating the nutrient data S323. In the data table, the nutritional component contained per unit weight is described for each food.

  The deficient nutrient calculation unit 324 calculates deficient nutrient data S324 based on the nutrient data S323. The deficient nutrient calculation unit 324 may create deficient nutrient data S324 for the nutrient data S323 corresponding to one scaled meal photo data S25, or corresponds to a plurality of scaled meal photo data S25. The deficient nutrient data S324 for the nutrient data S323 to be generated may be created.

  When the deficient nutrient data S324 is created for the nutrient data S323 corresponding to the multiple-time meal photo data S25, the second control unit 32 stores the nutrient data in the second storage unit 33 each time the nutrient data S323 is calculated. S323 is stored. In this way, deficient nutrient data S324 can be calculated in consideration of past meal contents.

  The food proposal unit 325 calculates, as recommended food data S325, a food or menu that can efficiently supplement the user's deficient nutrients based on the deficient nutrient data S324.

<1-2. Flow of nutrient analysis process>
Next, the flow of nutrient analysis processing using the nutrient analysis system 1 will be described with reference to FIGS. FIG. 7 is a flowchart showing the flow of nutrient analysis processing. 8 and 9 are flowcharts showing the flow of the meal photo data acquisition process with scale. FIG. 10 is a flowchart showing the flow of the meal information input process. FIG. 11 is a flowchart showing the flow of the meal content analysis process. FIG. 12 is a diagram illustrating an example of an information input screen.

  As shown in FIG. 7, in the nutrient analysis process in the nutrient analysis system 1, first, meal photo data S25 with a scale is acquired (step ST1). Thereby, the image which shows the amount of meal visually and quantitatively is acquired. A specific flow of step ST1 will be described with reference to FIGS.

  First, a case where a scale is manually applied will be described with reference to FIG. As shown in FIG. 8, the scale member 40 is set near the meal (step ST11). Then, the image acquisition unit 25, which is a camera of the smart phone 2a, performs photographing so that both the whole meal and the scale member 4 are framed in (step ST12). Thereby, the 1st control part 21 acquires meal photo data S25 with a scale. And the meal photo data S25 with a scale is preserve | saved in the 1st memory | storage part 22 (step ST13).

  Next, a case where a scale is automatically assigned will be described with reference to FIG. As shown in FIG. 9, the image acquisition unit 25, which is a camera of the smart phone 2a, is activated in the scale assignment mode (step ST14). Then, the lens 251 is directed toward the meal so that the entire meal is framed in. Accordingly, the first control unit 21 estimates the distance from the lens 251 to each part of the meal and the food table using the focus adjustment mechanism 252 and calculates scale data (step ST15). When the user inputs a shooting command to the input unit 24 of the smart phone 2a, the image acquisition unit 25 acquires image data obtained by shooting a meal. At the same time, the image acquisition unit 25 adds the scale data calculated in step ST15 to the image data, and acquires the meal photo data S25 with scale (step ST16). And the meal photo data S25 with a scale is preserve | saved in the 1st memory | storage part 22 (step ST17).

  As shown in FIG. 7, when the acquisition of the meal photo data with scale S25 in step ST1 is completed, the explanation data S24 is subsequently input (step ST2). This supplements information such as the date and time of meal, the type of food, and the seasoning that cannot be determined only by the meal photo data with scale S25. A specific flow of step ST2 will be described with reference to FIG.

  As shown in FIG. 10, in the input of the explanation data S24 in step ST2, first, the first control unit 21 recognizes each dish from the image of the scaled meal photo data S25 (step ST21). Then, the first control unit 21 causes the first display unit 23 to display an information input screen as shown in FIG. In the information input screen of the example of FIG. 12, a meal image is displayed at the top, and an input field is provided at the bottom. The information input screen in FIG. 12 shows a state where a dish with hamburger is selected.

  In the example of FIG. 12, the first control unit 21 recognizes five dishes, so that the dish numbers surrounded by circles 1 to 5 are shown. A menu name or the like can be input by selecting the plate number or the corresponding plate portion shown in the meal image. When the dish number 1 is selected from the first input unit 24, an input field for material name and memo appears below the menu name field. In the example of FIG. 12, “hamburg” is input as the menu name of the dish 1. In this way, the dish type is input (step ST22).

  Subsequently, ingredients are input for each input cooking type (step ST23). In the example of FIG. 12, “cooked meat”, “onion”, “carrot”, and “crumbs” are entered in the column of the hamburger material name of the plate 1. Then, for each material, an icon is selected that indicates whether each ingredient is included in a larger amount, a smaller amount, or a general amount as compared with a general hamburger. In the default state, “normal” indicating a general amount is selected for the icon. When the user feels that the amount of each ingredient is large, “many” is selected, and when the user feels that the amount is small, “small” is selected. Thereby, in the meal content analysis process (step ST4) on the center computer 3 side, the meal content can be analyzed more accurately.

  A part of the input of ingredients in step ST23 may be automated. In that case, a database including a dish type and a general material name for each dish type is stored in advance in the first storage unit 22. When the dish type input in step ST22 matches the dish type stored in the database, the first control unit 21 reads the material name corresponding to the dish type from the database, and displays the information input screen. The material name is automatically entered in the column. Thereafter, the user adds or deletes material names. Thus, if the material name is automatically input, the user's trouble of inputting meal information is further reduced.

  After inputting the ingredients, a comment is input (step ST24). In the comment, describe the seasoning (soy sauce taste, demiglace sauce taste, etc.) that is difficult to understand in the photograph. If there are no matters to be noted, the input of comments can be omitted. In addition, as in the example of FIG. 12, when a plurality of dishes are on the selected plate, the description of the garnished dishes can be described as a comment. If the seasoning is darker or lighter than general dishes, it is preferable to describe the content in the comments. In this manner, meal contents can be analyzed more accurately by inputting comments.

  The input of the explanation data S24 (step ST2) is completed by the above steps ST21 to ST24. Returning to FIG. When the input of the explanation data S24 is completed, the first control unit 21 subsequently transmits the meal photo data with scale S25 and the meal information to the center via the Internet 100 (step ST3). Subsequently, a meal flow analysis is performed in the center computer 3 (step ST4). A specific flow of step ST4 will be described with reference to FIG.

  As shown in FIG. 11, in the analysis of meal contents in step ST4, first, the amount of dishes is specified (step ST41). Specifically, the quantity estimation unit 321 calculates estimated data S321. At this time, the calculation of the amount may be performed for each dish, or may be performed for each dish when a plurality of dishes are separately placed on one dish.

  Next, the material for each dish is specified (step ST42). Specifically, by operating the second input unit by the operator, referring to the images of the explanation data S24 and the meal photo data S25 with scale, the material name and the ratio of each food ingredient are specified for each dish, The meal content data S35 is input. Note that all of this step ST42 may be performed manually by the operator, or predetermined items may be automatically input based on the explanation data S24.

  Then, based on the estimated data S321 obtained in step ST41 and the meal content data S35 input by the operator, the food material data creating unit 322 creates the food material data S322. Ingredient data S322 is a list of ingredients names and weights of each ingredient for the dishes shown in the scale-equipped meal photo data S25.

  Subsequently, nutrients are calculated (step ST43). Specifically, the nutrient data S323 is calculated by the nutrient calculation unit 323. Subsequently, deficient nutrients are calculated (step ST44). Specifically, the deficiency nutrient data S324 is calculated by the deficiency nutrient calculation unit 324. Finally, recommended ingredients and menus are analyzed (step ST45). Specifically, the recommended food data S325 is calculated by the food proposal unit 325.

  When the analysis of the meal content in step ST4 is completed, the analysis content is transmitted to the user (step ST5). In the present embodiment, in step ST5, the second communication unit 31 transmits the food material data S322, the nutrient data S323, the deficient nutrient data S324, and the recommended food data S326 to the smartphone 2a.

  The analysis content transmitted to the user may be any of the food data S322, the nutrient data S323, the deficient nutrient data S324, and the recommended food data S326.

  With the above configuration, the user's input burden can be reduced by analyzing the meal data S25 with scale and the explanation data S24 transmitted by the user on the center computer 3 side. That is, the user can obtain the meal data with scale S25 and the explanation data S24 only by transmitting to the center computer 3 based on the detailed data of the food contained in the meal and / or the detailed data of the food. The analysis results can be easily obtained.

  Thereby, it is possible to easily grasp the nutrients of foods that are difficult to measure for each food material such as eating out and meals. Further, even when the user creates a dish by himself, the troublesome weighing for each ingredient can be omitted. Therefore, it is possible to easily input meal contents for the purpose of nutrient analysis.

  In addition, acquisition of such meal photo data S25 with a scale and transmission to the center computer 3 are not restricted only to 3 meals. It is also preferred to obtain scaled meal photo data S25 for ingestion of soft drinks, snacks, supplements, vitamins and the like. Thereby, the user can grasp | ascertain the acquisition nutrient more correctly.

  In addition, there is a case where the food is left uneaten after the food is photographed before the meal and the scaled meal photo data S25 is acquired. In such a case, it is possible to perform nutrient analysis by subtracting the uneaten portion by photographing the uneaten state and transmitting it to the center computer 3.

  Similarly, after the meal corresponding to the meal photo data S25 with scale is completed, there may be a change. Also in this case, it is possible to accurately perform nutrient analysis by photographing a dish to be replaced and transmitting it to the center computer 3.

<2. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  In the meal content input system according to the present invention, as a check function, the first control unit or the second control unit determines whether the user has transmitted the scaled meal photo data S25 to the center computer 3 without excess or deficiency. May have a part.

  As an example of the check function, the meal content input system may have an input check function based on the weight measurement content. In this case, the weight is measured every day at a fixed time, and the user inputs the weight to the first input unit. And a judgment part carries out comparative analysis of the input energy amount acquired as a result of nutrient analysis, and a user's weight change. Thereby, it can be judged whether the user is inputting the meal content without excess or deficiency.

  As another example of the check function, the meal content input system may have an input check function based on blood pressure measurement content. In this case, the blood pressure is measured every day at a fixed time, and the user inputs the blood pressure into the first input unit.
