[0031] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the exemplary embodiments are not limited to the technology of the present invention.

[0032] First, an example of the overall configuration of the energy measurement system according to this exemplary embodiment will be described. Figure 1 2 is a block diagram showing an example of the overall structure of the energy measurement system 1 of the present exemplary embodiment. Figure 1 As shown, the energy measurement system 1 of this exemplary embodiment includes a server 4, a database 6, and a smartphone 10. The server 4 and the smartphone 10 are connected to each other in a state where they can communicate with each other via a wired or wireless network.

[0033] The energy measuring system 1 of the present exemplary embodiment is a system for measuring energy using a color developing component 30, and the color developing component 30 develops color with a concentration distribution corresponding to the applied energy when energy such as pressure, heat, and ultraviolet rays is applied. Specifically, the color developing component 30 after energy is applied is photographed by the camera 11 of the smartphone 10, and the energy applied to the color developing component 30 is derived from the photographic image 8 obtained by the photographing. The camera 11 of the smartphone 10 of the present exemplary embodiment is an example of the photographing device of the present invention. In addition, the smartphone 10 of the present invention is also an example of the energy measuring device of the present invention.

[0034] As the color developing component 30, for example, Prescale (registered trademark) (manufactured by FUJIFILM Corporation) that develops color with a concentration distribution corresponding to the amount of pressure applied can be applied. Prescale is obtained by coating a color forming agent and a color developer containing microcapsules containing a colorless dye on a sheet-like support. When pressure is applied to Prescale, the microcapsules are destroyed, and the colorless dye is adsorbed on the color developer and develops color. In addition, since the color forming agent contains a variety of microcapsules of different sizes and strengths, the amount of microcapsules destroyed by the applied pressure is different, and the color development concentration is also different. Therefore, by observing the color development concentration, the size of the pressure applied to Prescale and the pressure distribution can be measured.

[0035] For example, as the color developing member 30 , THERMOSCALE (trade name) (manufactured by FUJIFILM Corporation) that develops color with a concentration distribution corresponding to the amount of applied heat, UV SCALE (trade name) (manufactured by FUJIFILM Corporation) that develops color with a concentration distribution corresponding to the amount of applied ultraviolet light, etc. can be applied.

[0036] The server 4 of this exemplary embodiment is a server installed with a software program for providing a general-purpose computer with a database management system (DBMS) function. The server 4 acquires the photographic image 8 and the energy derived from the photographic image 8 from the smartphone 10 and stores them in the database 6. In addition, the connection method between the server 4 and the database 6 is not particularly limited, and for example, it can be a method of connecting through a data bus, or a method of connecting through a network such as NAS (Network Attached Storage) and SAN (Storage Area Network).

[0037] In this exemplary embodiment, when the camera 11 of the smartphone 10 is used to photograph the color developing component 30, as shown in FIG. Figure 1and the details will be described later. Figure 2 As shown, the user uses the camera 11 of the smartphone 10 to shoot with the color developing component 30 placed on the calibration component 20. As a result, the smartphone 10 acquires a photographic image 8 including the calibration component 20 and the color developing component 30. In this way, when the user shoots, the photographic image 8 is sometimes affected by the shooting environment such as the lighting environment in which the shooting is performed, the characteristics of the camera 11, the shooting angle, and the shooting distance. The calibration component 20 is a component for correcting these influences in the photographic image 8.

[0038] refer to Figure 2 and Figure 3 , the calibration component 20 of this exemplary embodiment is described in detail. In addition, Figure 2 The state in which the color developing member 30 is placed on the calibration member 20 is shown, and a surface of the calibration member 20 that is photographed in the state in which the color developing member 30 is placed (hereinafter referred to as “photographing surface 20S”) is shown.

[0039] like Figure 2 As shown, the photographing surface 20S includes a first area 20A on which the color developing component 30 is placed and a second area 20B on which a plurality of patches 25 are arranged. As an example, the first area 20A of this exemplary embodiment is the central area of ​​the photographing surface 20S and is surrounded by a frame 21. And, the second area 20B is the area around the first area 20A in the photographing surface 20S. In other words, the second area 20B is the area outside the frame 21 in the photographing surface 20S. In addition, the patches 25 of this exemplary embodiment are an example of the calibration image of the present invention.

[0040] The smartphone 10 of the energy measurement system 1 of the present exemplary embodiment uses the frame 21 shown on the imaging surface 20S of the calibration member 20 to correct the distortion, tilt and size of the photographic image 8 (described in detail later). In particular, if the frame 21 (i.e., the first area 20A) is rectangular, the accuracy of the correction of the distortion, tilt and size of the photographic image 8 can be improved, so the frame 21 is preferably rectangular.

[0041] Furthermore, the imaging surface 20S includes a plurality of patches 25 extending along the respective sides of the rectangular frame 21. Figure 2 As shown, as an example, in the second area 20B of the exemplary embodiment, a pair of first patch groups 22A and 22B are arranged at positions opposite to each other across the first area 20A. At least one of the first patch groups 22A and 22B includes a plurality of patches 25 of different colors. For example, at least one of the first patch groups 22A and 22B may include a plurality of patches 25 of the same hue and different concentrations. In other words, the colors of the plurality of patches 25 included in at least one of the first patch groups 22A and 22B may be different.

[0042] The color and number of the patches 25 included in the first patch group 22A may be the same as or different from the color and number of the patches 25 included in the first patch group 22B. Figure 2 As shown in FIG. 1 , the color and number of the patches 25 included in the first patch group 22A are set to be the same as the color and number of the patches 25 included in the first patch group 22B, but the arrangement of the patches 25 of each color is different. Figure 2 As shown, in the calibration component 20 of this exemplary embodiment, the first patch groups 22A and 22B have a plurality of patches 25 arranged in the X direction and the Y direction. In addition, it is preferred that the number of patches 25 arranged in the X direction (in Figure 2 ) is greater than the number of patches 25 arranged in the Y direction (in the example of 16). Figure 2 In the example, there are 2 or more.

[0043] And, if Figure 2 As shown, as an example, in the second region 20B of the present exemplary embodiment, a pair of second patch groups 24A and 24B are arranged at positions opposite to each other across the first region 20A. At least one of the second patch groups 24A and 24B includes a plurality of patches 25 of different colors. For example, at least one of the second patch groups 24A and 24B may include a plurality of patches 25 of the same hue and different concentrations. In other words, the colors of the plurality of patches 25 included in at least one of the second patch groups 24A and 24B may be different from each other.

[0044] The color and number of the patches 25 included in the second patch group 24A may be the same as or different from the color and number of the patches 25 included in the second patch group 24B. Figure 2 As shown, the color and number of the patches 25 included in the second patch group 24A are the same as the color and number of the patches 25 included in the second patch group 24B, but the arrangement of the patches 25 of each color is different. Figure 2 In the calibration component 20 of the exemplary embodiment shown in FIG. 1 , the second patch groups 24A and 24B have a plurality of patches 25 arranged in the X direction and the Y direction. In addition, it is preferred that the number of patches 25 arranged in the Y direction (in Figure 2 24 in the example) is greater than the number of patches 25 arranged in the X direction (in Figure 2 In the example, there are 2 or more.

[0045] The number of patches 25 included in each of the first patch groups 22A and 22B may be the same as or different from the number of patches 25 included in each of the second patch groups 24A and 24B. Figure 2, the number of patches 25 included in each of the first patch groups 22A and 22B is 32, and the number of patches 25 included in each of the second patch groups 24A and 24B is 48.

[0046] The color of at least one patch 25 included in at least one of the first patch groups 22A and 22B may be the same as the color of at least one patch 25 included in at least one of the second patch groups 24A and 24B. In other words, a patch 25 of the same color as a patch 25 included in at least one of the first patch groups 22A and 22B may be included in at least one of the second patch groups 24A and 24B. By including patches 25 of the same color in at least one of the first patch groups 22A and 22B and at least one of the second patch groups 24A and 24B, the accuracy of calibration of the photographic image 8 by the smartphone 10 can be improved (described in detail later).

[0047] At least one of the size, shape and angle of the plurality of patches 25 included in each of the first patch groups 22A and 22B and the second patch groups 24A and 24B may be the same. Figure 2 As shown, the plurality of patches 25 included in each of the first patch groups 22A and 22B and the second patch groups 24A and 24B have the same rectangular shape in size and angle.

[0048] Furthermore, the photographic surface 20S preferably includes a blank area between the first patch group and the second patch group included in at least one combination of the first patch group and the second patch group adjacent in the circumferential direction of the first region 20A. "The combination of the first patch group and the second patch group adjacent in the circumferential direction of the first region 20A" specifically refers to four combinations: a combination of the first patch group 22A and the second patch group 24A, a combination of the first patch group 22A and the second patch group 24B, a combination of the first patch group 22B and the second patch group 24A, and a combination of the first patch group 22B and the second patch group 24B. Figure 2 In FIG. 2 , the imaging plane 20S includes four blank areas 26 arranged between the first patch group and the second patch group adjacent to each other in the circumferential direction of the first region 20A (that is, all of the above four combinations).

[0049] Furthermore, the imaging surface 20S preferably includes a graphic 27 of a blank area 26 disposed between the first patch group and the second patch group. The graphic 27 is a graphic for indicating the range of the viewing angle that should be included when the user photographs the calibration component 20 and the color development component 30. Figure 2 As shown in FIG. 1 , the imaging surface 20S preferably includes four graphics 27 respectively arranged in four blank areas 26 so that the range to be included in the viewing angle can be easily understood. Figure 2In the example shown, the four graphics 27 respectively arranged in the four blank areas 26 are similar to each other. If the camera 11 is used to capture the photographic image 8 at a photographic position where the four graphics 27 respectively arranged in the blank areas 26 are within the field of view, the first patch group 22A and 22B, the second patch group 24A and 24B, and the color developing component 30 placed in the first area 20A can be captured in the field of view.

[0050] The calibration member 20 of the present exemplary embodiment includes a support 200 and a transparent member 202 , and a color developing member 30 is placed between the support 200 and the transparent member 202 . Figure 3 2 is a cross-sectional view of the calibration member 20 at a portion where the color developing member 30 is placed.

[0051] like Figure 3 As shown, the support body 200 of the present exemplary embodiment is a laminated body in which a first support body 200A and a second support body 200B are laminated. As an example, in the support body 200 of the present exemplary embodiment, the frame 21 and the patch 25 are formed on the first support body 200A. In addition, the frame 21 and the patch 25 are respectively provided on the first support body 200A. In addition, the frame 21 and the patch 25 can be respectively provided on the surface 200AS2 on the second support body 200B side of the first support body 200A, or can be provided on the surface 200AS1 on the side opposite to the surface 200AS2. Furthermore, the frame 21 can be provided on the surface 200AS1 and the patch 25 can be provided on the surface 200AS2, or the frame 21 can be provided on the surface 200AS2 and the patch 25 can be provided on the surface 200AS1, etc., and the frame 21 and the patch 25 can be provided on different surfaces.

[0052] On the other hand, the color developing member 30 is placed on the second support 200B. Specifically, in the second support 200B, the surface 200BS2 contacts the color developing member 30, and the surface 200BS1 contacts the surface 200AS2 of the first support 200. The second support 200B is a transparent member made of resin or the like.

[0053] Furthermore, the glossiness of the surface 200AS2 of the first support 200A is low, while the glossiness of the surface 200BS2 of the second support 200B is high. As described above, in the present exemplary embodiment, the color developing component 30 is arranged on the surface 200BS2 of the second support 200B of the support 200. The surface on which the color developing component 30 is arranged preferably does not produce stains, and is preferably whiter than the color developing component 30 that develops color. In the present exemplary embodiment, the surface unevenness of the surface 200BS2 of the second support 200B on which the color developing component 30 is placed is suppressed, and the glossiness is made high and becomes a relatively smooth state. Thus, in the support 200 of the present exemplary embodiment, stains are prevented from adhering to the surface 200BS of the second support 200B, and even if there are stains, it is easy to wipe. In this way, in the present exemplary embodiment, the state of the surface on which the color developing component 30 is placed can be well maintained.

[0054] On the other hand, the transparent member 202 is arranged on the coloring member 30 in a state of covering the coloring member 30. As an example, in the present exemplary embodiment, the size (area) of the transparent member 202 is set to be the same as that of the support 200. That is, the transparent member 202 of the present exemplary embodiment covers the entire support 200 in a state where the coloring member 30 is placed. For example, the coloring member 30 sometimes curls. Usually, the coloring member 30 is used by cutting out the required size (area) from a large state wound into a roll. Therefore, the cut coloring member 30 sometimes curls. And, when only placed on the support 200, the coloring member 30 may move. In the present exemplary embodiment, by covering the coloring member 30 with the transparent member 202, even when the coloring member 30 is rolled up, it can be flattened, and the coloring member 30 can be suppressed from moving from the placed state. In this exemplary embodiment, the size (area) of the transparent member 202 is set to be the same as that of the support 200, but the size of the transparent member 202 is not limited to this exemplary embodiment. The transparent member 202 is at least larger than the coloring member 30 as long as it can cover the entire coloring member 30.

[0055] In addition, in the present exemplary embodiment, the surface 202S on the side opposite to the color developing component 30 side in the transparent component 202 becomes the photographing surface 20S. Therefore, when photographing the color developing component 30, if the glossiness of the surface 202S of the transparent component 202 is high, there is a case where the reflected light reflected by the surface 202S increases, and the color of the image representing the color developing component 30 (hereinafter referred to as "the color developing component image") included in the photographic image 8 obtained by photographing becomes inappropriate. For example, in the above-mentioned Prescale for measuring pressure, the color is displayed in red according to the pressure, but if the reflected light is large, the color developing component image included in the photographic image 8 becomes white, which sometimes affects the measurement of energy. Therefore, in the present exemplary embodiment, the glossiness of the surface 202S of the transparent component 202, specifically, the surface 202S of the transparent component 202 that at least covers the color developing component 30 is reduced (i.e., low gloss), so as to suppress the reflected light generated during photographing. Furthermore, the glossiness of the surface 202S of the transparent member 202 covering the portion of the color developing member 30 is lower than the glossiness of the surface 200BS2 of the second support 200B. In addition, from the viewpoint of suppressing reflected light in order to make the color tone of the color developing member image included in the photographic image 8 appropriate, the glossiness of the surface 202S of the transparent member 202 is preferably 40 or less at a glossiness of 60°.

[0056] In the energy measurement system 1 of the present exemplary embodiment, when photographing the color developing member 30 as described above, the color developing member 30 is placed on the first region 20A of the support 200 of the calibration member 20, and photographed by the camera 11 in a state where the color developing member 30 is covered with the transparent member 202. Thus, a photographic image 8 including an image of the color developing member is obtained.

[0057] Next, the smartphone 10 of this exemplary embodiment will be described in detail. Figure 4 , an example of the hardware structure of the smart phone 10 is described. Figure 4 As shown, the smartphone 10 includes a CPU (Central Processing Unit) 80, a nonvolatile storage unit 82, and a memory 81 as a temporary storage area. In addition, the smartphone 10 includes a display 84 such as a liquid crystal display, an input unit 88, a network I / F (Interface) 86, and a camera 11. The CPU 80, the storage unit 82, the memory 81, the display 84, the input unit 88, the network I / F 86, and the camera 11 are connected in a manner that various information can be transmitted and received to each other via a bus 89 such as a system bus and a control bus.

[0058] The storage unit 82 is implemented by a storage medium such as a HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory. The storage unit 82 stores a measurement program 83. The CPU 80 reads the measurement program 83 from the storage unit 82, expands it in the memory 81, and executes the expanded measurement program 83. The CPU 80 is an example of a processor of the present invention, and the measurement program 83 is an example of an energy measurement program of the present invention.

[0059] The input unit 88 is used to receive user operations, such as a touch panel, a button, a keyboard, and a mouse. In addition, as an example, in the camera 11 of this exemplary embodiment, a touch panel display that integrates the display 84 and the input unit 88 is adopted. The network I / F 86 performs wired or wireless communication with the server 4 and other external devices (not shown). The camera 11 has a sensor having multiple spectral sensitivities different from each other, and uses the sensor to capture a subject under the control of the CPU 80, and outputs an image signal of the captured image 8.

[0060] Next, refer to Figure 5 , an example of the functional structure of the smart phone 10 is described. Figure 5 As shown, the smartphone 10 includes an acquisition unit 90, a calibration unit 92, a derivation unit 94, and a control unit 96. When the CPU 80 executes the measurement program 83, the CPU 80 functions as each functional unit of the acquisition unit 90, the calibration unit 92, the derivation unit 94, and the control unit 96.

[0061] The acquisition unit 90 acquires the photographic image 8 including an image showing the calibration member 20 (hereinafter referred to as “calibration member image”) and a color developing member image of the color developing member 30 , which is captured by the camera 11 .

[0062] The correction unit 92 extracts an image representing the frame 21 (hereinafter referred to as a "frame image") from the photographic image 8, and corrects at least one of the distortion, tilt, and size of the photographic image 8 based on the shape of the extracted frame image. As a method for extracting the frame image, a known method using edge extraction processing in an image can be appropriately applied. Specifically, when the frame 21 is a rectangle, the frame image also becomes a rectangle, and the correction unit 92 performs a projection transformation and an affine transformation, etc. so that the four corners of the frame image extracted from the photographic image 8 are 90 degrees, thereby correcting the distortion, tilt, and size of the photographic image 8.

[0063] Furthermore, the correction unit 92 calibrates the photographic image 8 acquired by the acquisition unit 90 using an image representing the patch 25 included in the photographic image 8 (hereinafter referred to as a "patch image"). Specifically, the correction unit 92 calibrates the color (for example, at least one of hue and concentration) of the color-developing component image included in the photographic image 8 based on the color of the patch image of the patch 25 included in each of the first patch group 22A and 22B and the second patch group 24A and 24 included in the photographic image 8. As a calibration method, a known method can be appropriately applied. For example, a reference color is pre-stored in the storage unit 82 for each patch 25 included in the calibration component 20, and the correction unit 92 adjusts the color of the photographic image 8 so that the color of each of the plurality of patch images included in the photographic image 8 is consistent with the respective reference color.

[0064] Furthermore, as described above, each of the first patch group 22A and 22B, and the second patch group 24A and 24B may include patches 25 of the same color. At this time, due to the influence of the photographic environment such as the lighting environment for shooting, the characteristics of the camera 11, the shooting angle, and the shooting distance, the patches 25 originally formed with the same color are sometimes displayed in different colors on the photographic image 8. Therefore, for example, the correction unit 92 can adjust the color of the photographic image 8 so that the average color of the patch image corresponding to the patch 25 formed with the same color is consistent with the reference color. Furthermore, for example, the correction unit 92 can adjust the color of the photographic image 8 so that the color of the patch image closest to the reference color among the patches 25 formed with the same color is consistent with the reference color.

[0065] Furthermore, the correction unit 92 may perform calibration using a part of the patch images of the plurality of patches 25 included in each of the first patch groups 22A and 22B and the second patch groups 24A and 24B.

[0066] Furthermore, for example, the calibration unit 92 may use different patches 25 for calibration depending on the type of the color developing component 30. For example, Prescale, which is an example of the color developing component 30, is manufactured in multiple varieties with different measurable pressure ranges, such as for low pressure, medium pressure, and high pressure. Furthermore, for example, as described above, as the color developing component 30, in addition to Prescale, THERMOSCALE and UVSCALE can also be used.

[0067] Therefore, the correction unit 92 can perform calibration using the patch images of a portion of the patches 25 that are predetermined according to the type of the coloring component 30 corresponding to the coloring component image, among the patch images of the plurality of patches 25 included in the first patch group 22A and 22B and the second patch group 24A and 24B. The correspondence between the type of the coloring component 30 and the patch 25 used for calibration can be pre-stored in the storage unit 82, for example. The type of the coloring component 30 photographed can be input by the user via the input unit 88, for example, or can be determined by adding an identification code indicating the type of the coloring component 30 to the coloring component 30 and reading the identification code from the photographic image 8 by the correction unit 92.

[0068] In this way, the correction unit 92 can correct the influence of the photographic environment such as the lighting environment, characteristics of the camera 11, shooting angle and shooting distance that may occur when the user takes the photo by correcting the distortion, tilt, size and color of the photographic image 8.

[0069] In addition, in the present exemplary embodiment, as described above, the calibration component 20 and the color development component 30 are photographed using the photography support device 40. The photography support device 40 makes the calibration component 20 and the color development component 30 and the camera 11 of the smartphone 10 in a predetermined positional relationship, and blocks external light, and uses the light irradiated from the predetermined lighting device 74 as photography light to photograph the calibration component 20 and the color development component 30. Therefore, in the present exemplary embodiment, the calibration component 20 and the color development component 30 can be photographed in a state where the influence of the photography environment is reduced. Thus, in the present exemplary embodiment, the photographic image 8 photographed by the camera 11 becomes an image in which the influence of the above-mentioned photography environment is reduced. Therefore, according to the present exemplary embodiment, the processing of correcting the above-mentioned color development component image can be appropriately reduced or eliminated, and the processing load related to the correction processing can be reduced.

[0070] The deriving unit 94 derives the energy applied to the color developing unit 30 based on the color of the color developing unit image calibrated by the correction unit 92. Specifically, data that predetermines the relationship between the energy applied to the color developing unit 30 and the color of the color developing unit 30 is stored in advance in the storage unit 82, and the deriving unit 94 can use the data to convert the color of the color developing unit image included in the photographic image 8 into energy. In addition, the data that predetermines the relationship between the energy applied to the color developing unit 30 and the color of the color developing unit 30 can also be prepared in advance for each type of the color developing unit 30 and stored in the storage unit 82.

[0071] Furthermore, the deriving unit 94 may derive various indices related to the energy applied to the color developing component 30. The various indices include, for example, energy distribution obtained by deriving the energy of each pixel of the color developing image corresponding to the color developing area (hereinafter referred to as the "color developing area") of the color developing component 30, and representative values ​​such as the maximum value, minimum value, average value, and central value of the energy of the color developing area. Furthermore, for example, the area of ​​the color developing area, the ratio of the area in the color developing area where the energy is within a predetermined range, the uniformity of the energy of the color developing area, and the load of the color developing area (the product of the area of ​​the color developing area and the average value of the energy). Furthermore, for example, when a benchmark is predetermined for the color developing degree (i.e., energy and energy distribution) of the color developing component 30, the degree of consistency or deviation from the benchmark.

[0072] The control unit 96 performs control to display the photographed image 8 corrected for distortion, tilt, size, and color by the correction unit 92 and various indices related to energy derived by the derivation unit 94 on the display 84 . Figure 6 2 shows an example of a screen D displayed on the display 84 by the control unit 96. The screen D displays the color component image 31 in the photographic image 8 and various indices related to energy derived from the color component image 31.

[0073] As shown in screen D, the control unit 96 can perform control to extract the color developing component image 31 from the photographic image 8 and display it on the display 84. Figure 6 The "pressurized area" in the screen D shown refers to the area of ​​the color-developing area. The "average pressure" refers to the average value of the energy of the color-developing area. The "load" refers to the product of the pressurized area and the average pressure. The "uniformity of pressure value" refers to the uniformity of the pressure value of the color-developing area.

[0074] Furthermore, the control unit 96 can accept input of supplementary information related to the photographic image 8. In the screen D, as an example of supplementary information related to the photographic image 8, the type of the color developing component 30, the pressure type, the room temperature and the humidity are displayed, and a pull-down menu P for accepting these inputs is displayed. In addition, as the "pressure type", there are instantaneous pressure indicating the magnitude of the pressure applied to the Prescale instantaneously and continuous pressure indicating the time integral of the magnitude of the pressure applied to the Prescale continuously. Furthermore, as supplementary information, for example, identification information of the calibration component 20, the color developing component 30, the user who applied energy to the color developing component 30, and the user who photographed the color developing component 30, the user's evaluation result of energy, and various inspection conditions can be cited.

[0075] Furthermore, the control unit 96 transmits at least one of the photographic image 8 before correction, the photographic image 8 after correction, the color component image 31, and the color component image 31 after correction based on the correction unit 92 to the server 4 via the network I / F 86. Furthermore, the control unit 96 transmits various indices related to the energy derived by the deriving unit 94 and the inputted supplementary information to the server 4. The server 4 associates the information received from the smartphone 10 (control unit 96) with the photographic image 8 and stores them in the database 6.

[0076] Next, refer to Figure 7 The function of the smartphone 10 according to the present exemplary embodiment will be described. In the smartphone 10, the CPU 80 executes the measurement program 83 to execute the measurement program 83. Figure 7 The measurement process is executed when the user instructs the start of the execution via the input unit 88, for example.

[0077] In step S100, the acquisition unit 90 acquires the photographic image 8 captured by the camera 11, which includes the calibration component image of the calibration component 20 and the color component image 31 of the color component 30. In the next step S102, the correction unit 92 extracts the frame image of the frame 21 from the photographic image 8 acquired in the above step S100, and corrects at least one of the distortion, tilt and size of the photographic image 8 based on the shape of the extracted frame image. In the next step S104, the correction unit 92 calibrates the color of the photographic image 8 (particularly the color component image 31 included in the photographic image 8) using the patch image included in the photographic image 8 corrected in the above step S102.

[0078] In the next step S106, the deriving unit 94 derives the energy applied to the color developing component 30 based on the color of the color developing component image 31 calibrated in the above step S104. In the next step S108, the control unit 96 controls the display 84 to display the color developing component image 31 calibrated in the above step S104 and the energy derived in the above step S106. By this control, Figure 6 The screen D shown is displayed on the display 84. When the processing of step S108 is completed, Figure 7 The information processing shown ends.

[0079] As described above, the calibration component 20 of the above-mentioned method is a calibration component used for calibrating the color component image in the photographic image 8 obtained by photographing the color component 30 that develops color with a concentration distribution corresponding to the applied energy by the camera 11. The calibration component 20 includes: a support 200 including a first area 20A on which the color component 30 is placed and a second area 20B on which the patch 25 for calibrating the color component image is arranged; and a transparent member 202 covering the color component 30 placed on the first area 20A of the support 200, and having a surface 202S as a photographic surface 20S with low gloss.

[0080] Thus, according to the calibration member 20 of the above-described embodiment, the color tone of the color developing member image included in the photographed image 8 obtained by photographing the color developing member 30 can be made appropriate.

[0081] In addition, the structure of the support body 200 is not limited to the above-mentioned method. For example, the first support body 200A and the second support body 200B may be integrated. In this case, for example, Figure 8 As shown, a support 200C as synthetic paper can be applied. As such synthetic paper, so-called YUPO paper can be used. And, for example, Fig. 9 As shown, a resin layer 200D can be used as the support body 200. In this case, the patch 25 is arranged on the resin layer 200B by printing or the like.

[0082] And, if Fig.10 As shown in FIG. 1 , the calibration component 20 may be provided with a grid line 29 that functions as a guide for configuring the color developing component 30. The grid line 29 is set to a color and thickness that do not affect the energy applied to the color developing component 30 when the color of the color developing component image 31 included in the photographic image 8 is derived. For example, in the above-mentioned Prescale for measuring pressure, the color is red according to the pressure, but in this case, the color of the grid line is preferably blue. In addition, in Fig.10 In the illustrated calibration member 20 , the grid lines 29 are shown to be provided in the first region 20A, but may be provided in the second region 290B.

[0083] Furthermore, in the above, as an example of the photographic device of the present invention, a method of applying the camera 11 of the smartphone 10 is described, but the photographic device is not limited to the camera 11 of the smartphone 10. For example, as the photographic device, a digital camera or the like provided separately from the smartphone 10 may also be applied. Furthermore, in the above, as an example of the energy measuring device of the present invention, a method of applying the smartphone 10 is described, but the energy measuring device is not limited to the smartphone 10. For example, as the energy measuring device, a tablet terminal, a wearable terminal, a personal computer, etc. may also be applied. Furthermore, in the above, a method of integrating the photographic device and the energy measuring device of the present invention into the smartphone 10 is described, but the photographic device and the energy measuring device may also be separate devices.

[0084] In the above-described embodiment, for example, various processors described below can be used as the hardware configuration of processing units that execute various processes, such as the acquisition unit 90 , the correction unit 92 , the derivation unit 94 , and the control unit 96 .

[0085] As described above, the various processors include, in addition to general-purpose processors, namely CPUs, that execute software (programs) and function as various processing units, processors having circuit structures that can be changed after manufacturing, such as FPGAs (Field Programmable Gate Arrays), namely programmable logic devices (PLDs), and processors having circuit structures specifically designed to perform specific processing, such as ASICs (Application Specific Integrated Circuits), namely dedicated circuits, among others.

[0086] One processing unit may be composed of one of these various processors, or a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, a combination of a CPU and an FPGA). Furthermore, multiple processing units may be composed of one processor.

[0087] As an example of a plurality of processing units being constituted by one processor, first, as represented by computers such as clients and servers, there is a method in which one processor is constituted by a combination of one or more CPUs and software, and the processor functions as a plurality of processing units. Second, as represented by a system-on-chip (SoC), there is a method in which a processor is used that realizes the functions of the entire system including a plurality of processing units by one IC (Integrated Circuit) chip. In this way, various processing units are constituted as a hardware structure using one or more of the above-mentioned various processors.

[0088] Furthermore, as the hardware configuration of these various processors, more specifically, a circuit (circuitry) formed by combining circuit elements such as semiconductor elements can be used.

[0089] Furthermore, in the above-mentioned exemplary embodiments, the method of pre-storing (installing) the measurement program 83 in the storage unit 82 is described, but the present invention is not limited to this. The measurement program 83 can be provided in a method of recording on a recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), and a USB (Universal Serial Bus) memory.
