[0011] <Embodiment> 1 shows an example of the overall configuration of a testing system according to this embodiment. The testing system according to this embodiment supports general users, such as non-medical professionals, in conducting tests using test media provided as test kits, for example. In this embodiment, there are no particular limitations on the diseases, test items, etc. that can be tested using the test medium.

[0012] The user terminal 100 is a terminal used by a user who performs an inspection using a test medium. An inspection application corresponding to the inspection using the test medium is installed in the user terminal 100. The processing of the user terminal 100 described below may be executed as a function realized by the inspection application.

[0013] The user terminal 100 may be, for example, a smartphone, or may be a tablet or a personal computer.

[0014] The medical-related information server 200 is communicably connected to each of the user terminals 100 via a network. The medical-related information server 200 stores medical-related information related to each user corresponding to, for example, the user terminal 100. The medical-related information may include, for example, electronic medical records, medical receipts, drug prescription history, and test results obtained using a testing application. The medical-related information server 200 transmits the medical-related information of the corresponding user to the user terminal 100, thereby making it possible to provide the medical-related information to the user.

[0015] The medical-related information server 200 may be configured by a plurality of devices on a network, and may be configured to realize predetermined functions by the plurality of devices communicating with each other. The medical-related information server 200 may also be configured as a cloud server.

[0016] An example of a procedure in which a user performs an inspection using the user terminal 100 will be described with reference to FIGS. To conduct a test, a user prepares a test medium corresponding to the disease being tested for. The test medium may include a test strip impregnated with a reagent. Such a test strip reacts to the analyte by producing a color change. When performing an examination, the user operates the user terminal 100 to display an examination start screen as an application screen of the examination application on the display unit. The examination start screen is an operation screen that is displayed first when starting a new examination.

[0017] 2 shows an example of an examination start screen. The examination start screen in the figure presents the corresponding user's profile (e.g., age, sex, height, weight). Such a profile may be presented based on information entered by the user when registering as a user for the examination application.

[0018] Furthermore, on the examination start screen, a "medical history" link LK11 is arranged. When the user operates the "medical history" link LK11, a medical history screen presenting the user's medical history is displayed (not shown). The medical history information presented on the medical history screen may be acquired by the user terminal 100 from the medical-related information server 200.

[0019] The test start screen also displays the history of tests the user has performed in the past. Specifically, the test start screen in the figure displays information about the most recent test performed in the past ("Latest Test Date" and "Results"). The test start screen also includes a "Previous Test Results" link LK12. When the user operates the "Test Results" link LK12, a test result history screen (not shown) is displayed, which shows the history of the results of tests that the user has performed using the test application. The test result information shown on the test result history screen may be obtained by the user terminal 100 from the medical-related information server 200.

[0020] The test start button BT11 on the test start screen is a button operated to instruct the test application to start an operation according to the test. The user applies a sample to the test paper of the test medium to cause a change in color of the test paper, and then operates the test start button BT11.

[0021] In response to the operation of the examination start button BT11, the display on the display unit of the user terminal 100 transitions to an examination setting screen. FIG. 3 shows an example of the test setting screen. The test setting screen is a screen for setting the test subject. Specifically, the test subject is specified on the test setting screen in the same figure. In this embodiment, it is possible to test a predetermined number of test subjects. On the test setting screen, the test subject is specified by selecting the type of test strip. Specifically, the test setting screen in the figure includes a test strip selection area AR21. The test strip selection area AR21 in the figure is used to select a test strip that corresponds to the test medium to be used for the test from among the test strip types prepared in advance in a pull-down menu format. The user operates the test strip selection area AR21 to select a test strip that corresponds to the test medium to be used for the test. In response to an operation to select a test strip, a test subject corresponding to the selected test strip is presented in the test subject area AR22.

[0022] After selecting the test paper in this way, the user operates the camera image display button BT21 arranged on the test setting screen. In response to the operation of the camera image display button BT21, the display on the display unit of the user terminal 100 transitions to an imaging operation screen (an example of the first screen).

[0023] 4 shows an example of the image capture operation screen, which is a screen on which an operation for capturing an image of a test paper in the test medium is performed. The imaging operation screen in the figure includes a captured image area AR31. The captured image area AR31 is an area where a through image currently captured by an imaging unit (camera) included in the user terminal 100 is displayed.

[0024] A guide frame FL is fixedly displayed at a predetermined position in the captured image area AR31. The guide frame FL is a frame that guides the position of the test strip in the captured image. The size and shape of the guide frame FL in the captured image area AR31 may be changed depending on the type of test strip selected by operating the test setting screen. The user adjusts the position of the image captured by the imaging unit of the user terminal 100 so that the image portion (test strip image) OBJ of the test medium fits as large as possible within the guide frame FL in the captured image area AR31.

[0025] Furthermore, there is an ideal range for the imaging angle of the imaging unit of the user terminal 100 relative to the test paper, taking into consideration, for example, distortion of the test paper being imaged. The user terminal 100 may determine whether the imaging angle of the imaging unit is within a predetermined range based on, for example, the orientation of the user terminal 100 determined based on the detection output of an angular velocity sensor or the degree of distortion of the shape of the test paper in the through image, and if it is not within the predetermined range, may provide guidance to bring it into the ideal range. For example, if the user terminal 100 determines that the imaging angle of the imaging unit is outside the ideal range, it may display an imaging angle guidance screen that guides the user to bring the imaging angle of the imaging unit into the ideal range.

[0026] 5 shows an example of an imaging angle guidance screen, which provides guidance on how to point the user terminal 100 so that the imaging angle of the imaging unit falls within an ideal range. Such an imaging angle guide screen may be displayed as a pop-up screen superimposed on the imaging operation screen as a screen related to the imaging operation screen, or may be displayed so that transition between the imaging operation screen and the other screens is possible depending on the operation, or may be placed within the imaging operation screen.

[0027] Returning to the explanation in Figure 4, the user operates the capture and record button BT31 after ensuring that the test strip image OBJ, captured at a good imaging angle, is contained at a sufficient size within the guide frame FL in the captured image area AR31. The user terminal 100 executes image capture and recording at the timing when the image capture and recording button BT31 is operated. That is, the user terminal 100 stores in the storage unit the captured image captured by the imaging unit at the timing when the image capture and recording button BT31 is operated. The captured image thus obtained by image capture and recording may be a still image.

[0028] The user terminal 100 performs a quality assessment on the portion of the test strip to be inspected (the inspection target portion) in the captured image stored in the memory unit in response to operation of the image capture / record button BT31. In other words, the user terminal 100 determines whether or not the portion of the test strip in the captured image satisfies the quality conditions that allow an appropriate test value to be obtained (whether or not an imaging error has occurred). Specifically, if the brightness of the test paper portion in the captured image is higher than a certain level relative to the brightness set as a standard value, the user terminal 100 may determine that the test paper portion is glossy and does not meet the quality conditions. In addition, if the difference in brightness between multiple reagents in the test paper portion of the captured image is greater than a certain level, the user terminal 100 may determine that the quality conditions are not met, for example, because a shadow is cast on part of the test paper. Furthermore, if the test paper portion of the captured image is out of focus, the user terminal 100 may determine that the quality condition is not satisfied. Whether the test paper portion of the captured image is out of focus may be determined by whether the concentration of low frequencies in the power spectrum image of the test paper portion of the captured image is equal to or greater than a certain level. Furthermore, the user terminal 100 may determine whether or not dust is present in the test paper portion of the captured image by, for example, comparing the test paper portion of the captured image with an image of a standard test paper portion. If the user terminal 100 determines that dust is present, it may determine that the quality conditions are not met.

[0029] When the user terminal 100 determines that the test paper portion of the captured image does not satisfy the quality conditions as described above, the user terminal 100 may display a re-imaging prompt screen on the display unit to prompt the user to capture and record the image again (re-imaging). 6 shows an example of a re-imaging guidance screen. A guidance message area AR41 is arranged on the re-imaging guidance screen in the same figure. A message urging the user to re-imaging is presented in the guidance message area AR41. The message presented in the guidance message area AR41 may also indicate what the user should pay attention to when re-imaging depending on the reason why the quality condition was not satisfied.

[0030] Note that the captured image determined not to satisfy the quality condition may be displayed on the imaging guide screen, or the captured image determined not to satisfy the quality condition may be displayed in response to a predetermined operation on the imaging guide screen.

[0031] When the user wishes to perform re-imaging, he or she operates the re-imaging button BT41 arranged on the re-imaging guide screen. When the re-imaging button BT41 is operated, the user terminal 100 displays an imaging operation screen on the display unit, and enters a state in which re-imaging is possible. On the other hand, if the user determines that re-imaging is not necessary, he or she operates the skip button BT42 arranged on the re-imaging guidance screen.

[0032] If the captured image obtained by the image capturing and recording satisfies the quality conditions, or if the skip button BT42 on the re-imaging guidance screen is operated, the user terminal 100 performs an inspection on the test paper area in the captured image to obtain the inspection results. The user terminal 100 displays an inspection result screen (an example of a second screen) on the display unit, which presents the inspection results.

[0033] 7 shows an example of the test result screen. The test result screen in the same figure has a captured image confirmation area AR51. In the captured image confirmation area AR51, a test strip image OBJ, which is the test strip portion of the captured image that was the test target, is displayed.

[0034] Furthermore, the test result screen has a test result area AR52. The test result area AR52 shows details of the test results. In the test result area AR52 in the same figure, an example is shown in which the test results include a comprehensive judgment result on the presence or absence of abnormalities and the test values ​​for each test item.

[0035] The test result screen also displays a reagent coloration result area AR53. The reagent coloration result area AR53 displays the color of the corresponding portion (reagent portion) for each of multiple reagents (four in the figure) extracted from the test paper portion of the captured image. For comparison, the reagent coloration result area AR53 also displays a corresponding standard color obtained for each reagent portion corresponding to a normal value.

[0036] The color of the reagent portion in the captured image depends on the characteristics of the image capture unit, and so if the image is displayed on a display unit with different characteristics, the correct color may not be reproduced, making it difficult to properly compare the image with a standard color prepared in advance. Therefore, the user terminal 100 may perform color correction on the color of the reagent portion presented in the reagent coloration result area AR53 so that it has the same characteristics as the standard color. To do this, the user terminal 100 may calculate the color of each reagent in the captured image as a colorimetric value in a color space such as the XYZ colorimetric system or sRGB, and convert each calculated colorimetric value into a value in the display color space applied to the user terminal 100. The user terminal 100 may display the color of the reagent portion in the reagent coloration result area AR53 using the value in the display color space converted in this way.

[0037] When the user wants to save the test results presented on the test result screen, the user operates the save button BT51 arranged on the test result screen. In response to the operation of the save button BT51, the user terminal 100 stores test result information indicating the test results presented on the test result screen. On the other hand, if the user views the test results presented on the test result screen and decides to perform the test again, the user operates the re-image button BT52. When the re-image button BT52 is operated, the user terminal 100 displays an image capture operation screen on the display unit, making it possible to perform re-imaging.

[0038] In this manner, in this embodiment, the user can perform the test by a simple procedure of capturing an image of the test paper portion of the test medium using, for example, a smartphone on which a test application is installed. Furthermore, in this embodiment, although simple, the guide frame FL is used to guide the position of the test paper and to provide guidance for setting the appropriate imaging angle, so good test results can be expected.

[0039] An example of the functional configuration of the user terminal 100 will be described with reference to Fig. 8. The user terminal 100 may be configured with, as hardware, a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage devices such as HDD (Hard Disk Drive) and SSD (Solid State Drive). The user terminal 100 may also be configured with a GPU (Graphics Processing Unit) as hardware. The functions of the user terminal 100 shown in Fig. 8 are realized by the CPU and GPU provided in the user terminal 100 executing programs.

[0040] The user terminal 100 in the figure includes a communication unit 101, an operation unit 102, a display unit 103, an imaging unit 104, a control unit 105, and a storage unit 106.

[0041] The communication unit 101 communicates with the medical-related information server 200 via a network.

[0042] The operation unit 102 includes an operator or an input device provided in the user terminal 100, or an input device connected to the user terminal 100, and receives operations performed by the user.

[0043] The display unit 103 displays an image under the control of the control unit 105. Note that the operation unit 102 and the display unit 103 may be provided as a touch panel that combines a touch pad as an input device with a display device.

[0044] The imaging unit 104 captures an image to obtain a captured image.

[0045] The control unit 105 executes various controls in the user terminal 100. The control unit 105 includes a display control unit 151 (an example of a first display control unit or a second display control unit), an image quality determination unit 152, a color correction unit 153, and an inspection unit 154. The treatment planning unit 155 is a functional unit corresponding to a modified example described later, and therefore a description thereof will be omitted here.

[0046] The display control unit 151 executes control relating to the display on the display unit 103. The display control unit 151 causes the display unit 103 to display each of the screens shown in Fig. 2 to Fig. 7 under the operation of the inspection application.

[0047] The image quality determination unit 152 determines whether or not a captured image obtained in response to an operation for capturing and recording satisfies a predetermined quality condition.

[0048] The color correction unit 153 performs color correction on the portion of the test paper in the captured image for each reagent.

[0049] The inspection unit 154 performs an inspection based on the portion of the test paper in the captured image that is obtained in response to an image recording operation and that is the inspection target.

[0050] The storage unit 106 stores various types of information related to the user terminal 100. The storage unit 106 includes a guide frame data storage unit 161, an examination reference information storage unit 162, and an examination result information storage unit 163.

[0051] The guide frame data storage unit 161 stores guide frame data corresponding to each test strip that can be selected by operating the test setting screen. The guide frame data is data used to display the guide frame FL in the captured image area AR31 of the imaging operation screen. The guide frame data corresponding to one guide frame FL may be data indicating the size and shape of the corresponding guide frame FL.

[0052] The test reference information storage unit 162 stores test reference information. The test reference information is information that is referenced when the testing unit 154 performs a test. The test reference information may include, for example, a color chart for each reagent and a test value for each color of the color chart.

[0053] The test result information storage unit 163 stores the test result information. The test result information is information indicating the test results by the test unit 154.

[0054] An example of a processing procedure executed by the user terminal 100 in response to an examination will be described with reference to the flowchart of FIG. Step S100: In the user terminal 100, the display control unit 151 causes the display unit 103 to display an inspection start screen (FIG. 2) of the inspection application in response to a user operation.

[0055] Step S102: The display control unit 151 accepts an examination start operation performed by the user while the examination start screen is displayed. The examination start operation is an operation on the examination start button BT11 arranged on the examination start screen.

[0056] Step S104: The display control unit 151 causes the display unit 103 to display an examination setting screen (FIG. 3) in response to receiving the examination start operation.

[0057] Step S106: The display control unit 151 selects a test strip to be tested in response to an operation to select a test strip in the test strip selection area AR21 on the test setting screen.

[0058] Step S108: The display control unit 151 generates an imaging operation screen (FIG. 4) in response to an operation performed on the camera image display button BT21 arranged on the examination setting screen. When generating the imaging operation screen, the display control unit 151 embeds a through image output from the imaging unit 104 in the captured image area AR31. When displaying the imaging operation screen, the display control unit 151 acquires guide frame data corresponding to the test paper selected in step S106 from the guide frame data storage unit 161, and places a guide frame FL generated using the acquired guide frame data at a predetermined position in the captured image area AR31. The display control unit 151 causes the generated imaging operation screen to be displayed on the display unit 103.

[0059] Furthermore, when the imaging operation screen is displayed, the display control unit 151 determines whether the imaging angle of the imaging unit 104 is within a predetermined range, and if it determines that it is not within the predetermined range, it displays an imaging angle guide screen.

[0060] Step S110: With the imaging operation screen displayed, the display control unit 151 waits for an operation (imaging record operation) to be performed on the imaging record button BT31. If an imaging record operation has not been performed, the process returns to step S108, and the display of the imaging operation screen continues.

[0061] Step S112: When an image capturing and recording operation is performed, the image quality determining unit 152 captures the captured image obtained by the image capturing unit 104.

[0062] Step S114: The image quality determination unit 152 determines whether the captured image acquired in step S112 satisfies the quality condition.

[0063] Step S116: If it is determined in step S114 that the captured image satisfies the quality condition, the display control unit 151 causes the display unit 103 to display a re-imaging guidance screen (FIG. 6).

[0064] Step S118: While the re-imaging guidance screen is being displayed, the display control unit 151 determines whether or not an operation has been performed on the re-imaging button BT41 (a re-imaging instruction operation). If a re-imaging instruction operation is performed, the process returns to step S108, whereby the imaging operation screen is displayed again and imaging can be performed again.

[0065] Step S120: If it is determined in step S114 that the quality conditions are met, or if in step S118 an operation (skip operation) is performed on the skip button BT42 instead of the re-image button BT41, the color correction unit 153 performs color correction on the reagent portion of the test paper in the captured image acquired in step S112.

[0066] Step S122: The inspection unit 154 performs an inspection on the reagent portion of the test strip that has been color-corrected in step S120. The inspection unit 154 may obtain the inspection result by, for example, comparing the color chart indicated by the test usage information stored in the test reference information storage unit 162 with the reagent portion of the color-corrected test strip, and obtaining the inspection value corresponding to the color of the matching color chart.

[0067] Step S124: The display control unit 151 generates a test result screen (FIG. 7) that presents the test results obtained in step S122. The display control unit 151 generates a test result screen including a captured image confirmation area AR51 in which the test strip image OBJ in the captured image color-corrected in step S120 is arranged, a test result area AR52 showing the test result in step S122, and a reagent coloration result area AR53 in which a color chart for each standard reagent and the color for each reagent in the captured image color-corrected in step S120 are arranged. The display control unit 151 causes the display unit 103 to display the generated test result screen.

[0068] Step S126: In response to an operation on the save button BT51 located on the test result screen displayed in step S124, the test unit 154 stores test result information indicating the test results obtained in step S122 in the test result information storage unit 163.

[0069] <Modification> A modification of this embodiment will now be described. [First Modification] An inspection system may be configured by connecting the user terminal 100 and the inspection server so that they can communicate with each other. In this modification, the inspection server may be configured to have at least one of the functions of the display control unit 151, the image quality determination unit 152, the color correction unit 153, and the inspection unit 154 shown in FIG.

[0070] [Second Modification] The control unit 105 of the user terminal 100 in this modification includes a treatment planning unit 155 (FIG. 8). The treatment planning unit 155 formulates a treatment plan according to the test results obtained by the testing unit 154. When formulating the treatment plan, the treatment planning unit 155 may formulate the treatment plan by using medical-related information of the corresponding user stored in the medical-related information server 200. In this case, the medical-related information may be a medical record or a medical receipt. The treatment planning unit 155 may estimate the user's medical history, etc. based on the medical record or the medical receipt, and use the estimated medical history in creating the treatment plan.

[0071] The display control unit 151 (an example of a third display control unit) may generate a diagnosis result related screen that presents the treatment plan formulated by the treatment formulation unit 155 together with the diagnosis result, and display the generated diagnosis result related screen on the display unit 103.

[0072] Furthermore, the treatment planning unit 155 may identify a medical institution where the user should receive treatment and include information guiding the identified medical institution in the treatment plan. In this case, the treatment planning unit 155 may identify, among medical institutions that can treat the corresponding disease, a medical institution that is located, for example, closest to the user's address entered during user registration, as the medical institution where the user should receive treatment. The display control unit 151 may, as guidance for the identified medical institution on the diagnosis result-related screen, for example, show the location of the medical institution on a map or present route guidance from the user's home to the medical institution. Then, the treatment planning section 155 may generate notification information to be notified to the identified medical institution when the user receives treatment at the medical institution. In this case, the display control unit 151 may guide the user to the medical institution identified by the treatment planning unit 155, generate a diagnosis result-related screen including notification information to be notified to the medical institution, and display the screen on the user terminal 100. The user can, for example, go to the medical institution guided on the displayed diagnosis result-related screen to receive treatment. Furthermore, when receiving treatment at a medical institution, the user can display the diagnosis result-related screen on the user terminal 100 and convey the notification information presented on the displayed diagnosis result-related screen to the doctor.

[0073] The treatment planning unit 155 may also be able to make an appointment for a medical examination through the reservation system of a medical institution that the user has specified as a place where the user should receive treatment. In this case, the treatment planning unit 155 may determine an appointment time by checking the reservation status indicated by the reservation system against the user's schedule information, and make a reservation in the reservation system at the determined appointment time.

[0074] The treatment planning unit 155 may be provided in the examination device in the first modified example. In this case, the treatment planning unit 155 may transmit a screen presenting the formulated treatment plan and the like to the user terminal 100, and the user terminal 100 may display the transmitted screen.

[0075] Note that a program for implementing the functions of the user terminal 100 and the medical-related information server 200 may be recorded on a computer-readable recording medium, and the program may be loaded into a computer system and executed to perform the functions of the user terminal 100 and the medical-related information server 200. Here, "loading a program recorded on a recording medium into a computer system and executing it" includes installing the program on a computer system. The term "computer system" here includes hardware such as an operating system and peripheral devices. The term "computer system" may also include multiple computer devices connected via a network, including the Internet, a wide area network (WAN), a local area network (LAN), or a dedicated line. The term "computer-readable recording medium" refers to portable media such as floppy disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as HDDs and SSDs built into a computer system. Thus, a recording medium storing a program may be a non-transitory recording medium such as a CD-ROM. The term "recording medium" also includes internal or external recording media accessible from a distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code executable on the terminal device. In other words, the format in which the program is stored on the distribution server does not matter as long as it can be downloaded from the distribution server and installed in a form that is executable on the terminal device. The program may be divided into multiple parts, each of which may be downloaded at different times and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a storage medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that serves as a server or client when a program is transmitted over a network. The program may also be one that realizes part of the functions described above.Furthermore, the above-mentioned functions may be realized in combination with a program already recorded in the computer system, that is, a so-called differential file (differential program).
