Description

Imaging support apparatus, energy measurement apparatus, energy measurement method, and energy measurement program

[0001] The present disclosure relates to an imaging support apparatus, an energy measurement apparatus, an energy measurement method, and an energy measurement program.

[0002] Conventionally, there has been known a technique for measuring an energy amount using a color-developing member that develops color in response to energy such as applied pressure, heat, and ultraviolet rays. An example of such a color-developing member is Prescale (registered trademark) (manufactured by FUJIFILM Corporation), which provides a color density corresponding to an applied pressure.

[0003] For example, International Publication No. 2021 / 235364 discloses a technique for converting a density value of a pressure measurement sheet into a pressure value based on an image representing a color-developing member included in a captured image obtained by placing a pressure measurement sheet (e.g., Prescale) on a calibration sheet and capturing an image of the pressure measurement sheet.

[0004] When imaging is performed in a state where an imaging light source is provided and the color-developing member is irradiated with light from the light source, reflected light may cause the light source to be reflected in the captured image.

[0005] The present disclosure has been made in consideration of the above circumstances, and an object of the present disclosure is to provide an imaging support apparatus, an energy measurement apparatus, an energy measurement method, and an energy measurement program, capable of obtaining a captured image in which reflection of a light source is suppressed when capturing an image of a color-developing member for energy measurement.

[0006] In order to achieve the above object, an imaging support apparatus according to a first aspect of the present disclosure comprises: a support member provided on at least a part of the periphery of a color-developing member that develops color with a density distribution corresponding to an amount of applied energy, the support member extending in a direction toward an imaging apparatus that captures an image of the color-developing member; and a light source supported by at least a partial region of a surface of the support member on a side of the color-developing member in a state of extending in a direction surrounding the color-developing member, the light source irradiating the color-developing member with light.

[0007] An imaging support apparatus according to a second aspect is the imaging support apparatus according to the first aspect, wherein the support member is a wall-shaped member having a predetermined width.

[0009] The fourth embodiment of the imaging support device is the imaging support device of the third embodiment, wherein the light source is positioned so that specularly reflected light from light incident on the surface of the end of the calibration member does not enter the imaging device.

[0010] The fifth embodiment of the imaging support device is the same as the imaging support device of the fourth embodiment, wherein the light source is positioned such that the angle of incidence of specularly reflected light incident on the surface of the end of the calibration member is greater than that of light incident on the imaging device.

[0011] The sixth embodiment of the imaging support device is the imaging support device of the third embodiment in which the angle between the normal to the light source and the line connecting the light source and the surface of the calibration member is 40 degrees or less.

[0012] The seventh embodiment of the photographic support device is the same as the photographic support device of the first embodiment, further provided with a top plate portion that covers the color-developing member and is located on the upper side of the support member.

[0013] The eighth aspect of the imaging support device is the same as the first aspect of the imaging support device, wherein the support member has two pairs of opposing support parts, and the light source is provided in at least one of the pairs.

[0014] The ninth embodiment of the photographic support device is the same as the first embodiment of the photographic support device, wherein the side of the support member facing the color-developing member is black.

[0015] The imaging support device of the tenth embodiment further comprises a holding member for holding a calibration member, in the imaging support device of the third embodiment.

[0016] The 11th embodiment of the imaging support device further includes an insertion section in the third embodiment that allows a calibration member to be inserted into and removed from the interior surrounded by a support member.

[0017] In the twelfth embodiment of the photographic support device, the color-generating member is covered with a colorless and transparent transparent member, as in the photographic support device of the first embodiment.

[0018] Furthermore, in order to achieve the above objective, the energy measuring device of the 13th aspect of the present disclosure comprises at least one processor, the processor and a shooting support device comprising: a support member provided in at least a part of the periphery of a color-developing member that develops color in a density distribution corresponding to the amount of energy applied, and extending in the direction of a shooting device that photographs the color-developing member; and a light source supported in at least a part of the area of ​​the surface of the support member on the side of the color-developing member, extending in the direction surrounding the color-developing member, and irradiating light onto the color-developing member, the processor and a shooting support device that acquires a color-developing member image representing the color-developing member photographed by the shooting device, and using data in which the relationship between the amount of energy applied to the color-developing member and the color of the color-developing member image is predetermined, the energy applied to the color-developing member is derived based on the color of the color-developing member image.

[0019] Furthermore, in order to achieve the above objective, the energy measurement method of the 14th aspect of this disclosure is a method for a computer to perform a process to derive the amount of energy applied to a color-developing member based on the color of the color-developing member, using a photographic support device which includes a support member provided in at least a part of the periphery of a color-developing member that develops color in a density distribution corresponding to the amount of energy applied, and extending in the direction of a photographic device that photographs the color-developing member, and a light source supported in at least a part of the area of ​​the surface of the support member on the side of the color-developing member, in a manner that extends in a direction surrounding the color-developing member, and irradiates light onto the color-developing member.

[0020] Furthermore, in order to achieve the above objective, the energy measurement program of the 15th aspect of this disclosure uses a photographing support device to acquire an image of a color-developing member representing the color-developing member captured by the photographing device, using data that has been predetermined regarding the relationship between the amount of energy applied to the color-developing member and the color of the color-developing member image, and causes a computer to perform a process to derive the amount of energy applied to the color-developing member based on the color of the color-developing member image. This process is performed using a photographing support device that includes a support member provided in at least a part of the periphery of a color-developing member that develops color in a density distribution corresponding to the amount of energy applied, and extending in the direction of a photographing device that photographs the color-developing member, and a light source supported in at least a part of the area of ​​the surface of the support member on the side of the color-developing member, in a manner that extends in a direction surrounding the color-developing member, and irradiates light onto the color-developing member.

[0021] According to this disclosure, when photographing a color-emitting element for measuring energy, it is possible to obtain a photographic image in which the reflection of the light source is suppressed.

This is a diagram showing an example of the appearance of a modified shooting box.

[0023] Embodiments of this disclosure will be described in detail below with reference to the drawings. These embodiments are not intended to limit the technology of this disclosure.

[0024] First, an example of the overall configuration of the energy measurement system of this embodiment will be described. Figure 1 shows a configuration diagram representing an example of the overall configuration of the energy measurement system 1 of this embodiment. As shown in Figure 1, the energy measurement system 1 of this embodiment comprises a server 4, a database 6, and a smartphone 10. The server 4 and the smartphone 10 are connected to each other via a wired or wireless network, enabling them to communicate with each other.

[0025] The energy measurement system 1 of this embodiment is a system for measuring energy using a color-emitting member 30 that develops color in a density distribution corresponding to the amount of energy applied when energy such as pressure, heat, and ultraviolet light is applied. Specifically, the camera 11 of the smartphone 10 photographs the color-emitting member 30 after energy has been applied, and the amount of energy applied to the color-emitting member 30 is derived from the captured image 8 obtained by the photograph. The camera 11 of the smartphone 10 of this embodiment is an example of the photographing device of this disclosure. Furthermore, the smartphone 10 of this disclosure is also an example of the energy measurement device of this disclosure.

[0026] As the color-developing member 30, for example, Prescale (registered trademark) (manufactured by Fujifilm Corporation), which develops color with a density distribution corresponding to the applied pressure, can be used. Prescale is a sheet-like support coated with a color-developing agent containing microcapsules with a colorless dye and a color developer. When pressure is applied to Prescale, the microcapsules are destroyed and the colorless dye is adsorbed onto the color developer, causing color development. Furthermore, since the color-developing agent contains multiple types of microcapsules with different sizes and strengths, the amount of microcapsules destroyed and the resulting color density vary depending on the applied pressure. Therefore, by observing the color density, the magnitude and pressure distribution of the pressure applied to Prescale can be measured.

[0027] For example, the color-developing member 30 may be a thermoscale (product name) (manufactured by Fujifilm Corporation) that develops color in a density distribution corresponding to the amount of heat applied, or a UV scale (product name) (manufactured by Fujifilm Corporation) that develops color in a density distribution corresponding to the amount of ultraviolet light applied.

[0028] In this embodiment, the server 4 is a general-purpose computer with a software program installed that provides the functionality of a database management system (DBMS). The server 4 acquires the captured image 8 and the amount of energy derived from the captured image 8 from the smartphone 10 and stores them in the database 6. The connection method between the server 4 and the database 6 is not particularly limited; for example, they may be connected by a data bus, or they may be connected via a network such as a NAS (Network Attached Storage) or SAN (Storage Area Network).

[0029] In this embodiment, when the color-generating member 30 is photographed using the camera 11 of the smartphone 10, as shown in Figure 1 and Figure 2 (described in detail later), the user places the color-generating member 30 on the calibration member 20 and takes a photograph using the camera 11 of the smartphone 10. As a result, the smartphone 10 acquires a photographed image 8 that includes the calibration member 20 and the color-generating member 30. When the user takes a photograph in this manner, the photographed image 8 may be affected by the shooting environment, such as the lighting environment in which the photograph is taken, the characteristics of the camera 11, the shooting angle, and the shooting distance. The calibration member 20 is used to correct these effects on the photographed image 8.

[0030] The calibration member 20 of this embodiment will be described in detail with reference to Figure 2. The calibration member 20 is formed in the form of a sheet or plate from a support made of, for example, paper and resin. Figure 2 shows the state in which the color-developing member 30 is placed on the calibration member 20, and shows the surface of the calibration member 20 that is photographed with the color-developing member 30 placed on it (hereinafter referred to as the "photography surface 20S").

[0031] As shown in Figure 2, the imaging surface 20S includes a first region 20A on which the color-developing member 30 is placed, and a second region 20B on which a plurality of patches 25 are arranged. As an example, in this embodiment, the first region 20A is the central region of the imaging surface 20S and is surrounded by a frame 21. The second region 20B is the region surrounding the first region 20A on the imaging surface 20S. In other words, the second region 20B is the region outside the frame 21 on the imaging surface 20S. The patches 25 in this embodiment are an example of the calibration image of this disclosure.

[0032] In this embodiment, the smartphone 10 of the energy measurement system 1 corrects the distortion, tilt, and size of the captured image 8 using a frame 21 shown on the imaging surface 20S of the calibration member 20 (details will be described later). In particular, if the frame 21 (i.e., the first region 20A) is rectangular, the accuracy of correcting the distortion, tilt, and size of the captured image 8 can be improved, so it is preferable that the frame 21 is rectangular.

[0033] Furthermore, the imaging surface 20S includes a plurality of patches 25 extending along each side of the rectangular frame 21. As shown in Figure 2, as an example, in the second region 20B of this embodiment, a pair of first patch groups 22A and 22B are arranged opposite each other across the first region 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 with the same hue but different densities. 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 each be different.

[0034] The color and number of patches 25 included in the first patch group 22A may be the same as or different from the color and number of patches 25 included in the first patch group 22B. For example, in the calibration member 20 of this embodiment, as shown in Figure 2, the color and number of patches 25 included in the first patch group 22A are the same as those included in the first patch group 22B, but the arrangement of patches 25 of each color is different. Also, as shown in Figure 2, in the calibration member 20 of this embodiment, the first patch groups 22A and 22B have multiple patches 25 arranged in the X and Y directions, respectively. It is preferable that the number of patches 25 arranged in the X direction (16 in the example in Figure 2) is greater than the number of patches 25 arranged in the Y direction (2 in the example in Figure 2).

[0035] Furthermore, as shown in Figure 2, as an example, in the second region 20B of this embodiment, a pair of second patch groups 24A and 24B are arranged opposite each other across the first region 20A. At least one of the second patch groups 24A and 24B contains a plurality of patches 25 of different colors. For example, at least one of the second patch groups 24A and 24B may contain a plurality of patches 25 of the same hue but different densities. 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 each be different.

[0036] The color and number of patches 25 included in the second patch group 24A may be the same as or different from the color and number of patches 25 included in the second patch group 24B. For example, in the calibration member 20 of this embodiment, as shown in Figure 2, the color and number of patches 25 included in the second patch group 24A and the color and number of patches 25 included in the second patch group 24B are the same, but the arrangement of patches 25 of each color is different. In addition, in the calibration member 20 of this embodiment shown in Figure 2, the second patch groups 24A and 24B have multiple patches 25 arranged in the X direction and Y direction, respectively. It is preferable that the number of patches 25 arranged in the Y direction (24 in the example in Figure 2) is greater than the number of patches 25 arranged in the X direction (2 in the example in Figure 2).

[0037] The number of patches 25 in each of the first patch groups 22A and 22B may be the same as or different from the number of patches 25 in each of the second patch groups 24A and 24B. In Figure 2, the number of patches 25 in each of the first patch groups 22A and 22B is 32, and the number of patches 25 in each of the second patch groups 24A and 24B is 48.

[0038] 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 image 8 captured by the smartphone 10 can be improved (details will be described later).

[0039] The multiple patches 25 included in each of the first patch groups 22A and 22B, and the second patch groups 24A and 24B, may each have the same size, shape, and angle. In this embodiment, as shown in Figure 2, the multiple patches 25 included in each of the first patch groups 22A and 22B, and the second patch groups 24A and 24B, each have a rectangular shape with the same size and angle.

[0040] Furthermore, it is preferable that the imaging surface 20S includes a blank area located between the first patch group and the second patch group, which are included in at least one combination of the first patch group and the second patch group that are adjacent to each other in the circumferential direction of the first region 20A. Specifically, the "combinations of the first patch group and the second patch group that are adjacent to each other in the circumferential direction of the first region 20A" refer to four combinations: the combination of the first patch group 22A and the second patch group 24A, the combination of the first patch group 22A and the second patch group 24B, the combination of the first patch group 22B and the second patch group 24A, and the combination of the first patch group 22B and the second patch group 24B. In Figure 2, the imaging surface 20S includes four blank areas 26 located between each of the first patch group and the second patch group that are adjacent to each other in the circumferential direction of the first region 20A (i.e., all four of the above combinations).

[0041] Furthermore, it is preferable that the shooting surface 20S includes a figure 27 placed in a blank area 26 located between the first patch group and the second patch group. This figure 27 indicates the range that should be included in the field of view when the user photographs the calibration member 20 and the color-developing member 30. Therefore, in order to make it easy to understand the range that should be included in the field of view, it is preferable that the shooting surface 20S includes four figures 27 placed in each of the four blank areas 26, as shown in Figure 2. In the example shown in Figure 2, the four figures 27 placed in each of the four blank areas 26 are similar in shape to each other. If the camera 11 takes a photograph of the image 8 at a shooting position where the four figures 27 placed in each of these blank areas 26 are included in the field of view, the first patch groups 22A and 22B, the second patch groups 24A and 24B, and the color-developing member 30 placed on the first area 20A can be photographed so that they are all included in the field of view.

[0042] As shown in Figure 3, the color-developing member 30 in this embodiment is covered by a transparent member 34. In other words, the color-developing member 30 is placed between the calibration member 20 and the transparent member 34. Figure 3 shows a cross-sectional view of the calibration member 20 in the portion on which the color-developing member 30 is placed.

[0043] For example, the color-forming member 30 may be warped. In general, the color-forming member 30 is used by cutting out a required size (area) for measurement from a large material wound in a roll shape. Therefore, the cut-out color-forming member 30 may be warped in some cases. In addition, the color-forming member 30 may shift if it is simply placed on the calibration member 20. In the present embodiment, by covering the color-forming member 30 with the transparent member 34, even when the color-forming member 30 is warped, it can be flattened, and the displacement of the color-forming member 30 from the placed state can be suppressed. It should be noted that the size (area) of the transparent member 34 only needs to be a size (area) that covers at least the entire color-forming member 30. For example, the size (area) of the transparent member 34 may be equal to the size (area) of the calibration member 20.

[0044] The color-forming member 30 is photographed while being covered with the transparent member 34. In other words, the color-forming member 30 is photographed through the photographing box 40. Therefore, it is preferable that the transparent member 34 has high transmittance. In addition, in order to suppress the breakage of the color balance of the color-forming member 30 caused by light transmitting through the transparent member 34, it is preferable that there is no variation in spectral transmittance within the wavelength range of the photographing light used for photographing. Examples of the material of the transparent member 34 satisfying such conditions include an acrylic plate, polycarbonate, and the like.

[0045] In some cases, when photographing the color-generating member 30, a light source may be provided, and the camera 11 may be used to photograph the color-generating member 30 while it is illuminated by light from the light source. The light source is used, for example, to suppress the influence of the photographic light. The image representing the color-generating member 30 included in the photographed image 8 (hereinafter referred to as the "color-generating member image") is affected by the shooting environment, such as the lighting environment in which the shooting takes place, the characteristics of the camera 11, the shooting angle, and the shooting distance. In particular, the light irradiated onto the color-generating member 30 greatly affects the color of the color-generating member image included in the photographed image 8. Specifically, even when photographing the same color-generating member 30, the color of the color-generating member image included in the photographed image 8 may differ due to differences in the amount and wavelength of the light irradiated onto the color-generating member 30 during shooting (hereinafter referred to as the "photographic light"). In other words, the color of the color-generating member image included in the photographed image 8 is affected by the photographic light. In particular, light based on the shooting environment, such as natural light or light irradiated from the workplace lighting, may have different amounts of light and wavelengths. Therefore, if the shooting light is only light based on the shooting environment, the influence on the color of the color-generating component image included in the captured image 8 becomes significant. Furthermore, regarding the influence on the color of the color-generating component image included in the captured image 8, when transparent component 34, glossy color-generating component 30, or glossy calibration component 20 are used, the reflection of the light source becomes a significant problem.

[0046] Therefore, in this embodiment, in order to suppress the influence of light based on the shooting environment on the color of the color-generating member image included in the captured image 8, the color-generating member 30 is photographed by the camera 11 while light is irradiated from the side of the color-generating member 30 by a light source. Specifically, in this embodiment, the color-generating member 30 is photographed while the calibration member 20, on which the color-generating member 30 is placed, is housed in a shooting box 40 equipped with a light source.

[0047] The photographing box of the present embodiment will be described with reference to the drawings. Note that the photographing box 40 of the present embodiment is an example of the photographing support apparatus of the present disclosure. An example of the photographing box 40 of the present embodiment is shown in FIGS. 4 and 5. An example of the external appearance of the photographing box 40 is shown in FIG. 4. In addition, FIG. 5 schematically shows an example of a state in which the calibration member 20 having the color-developing member 30 placed thereon is accommodated in the photographing box 40.

[0048] As shown in FIGS. 4 and 5, the photographing box 40 is a housing including a bottom plate 42, side plates 46 (46A to 46D), and a top plate 44.

[0049] The side plates 46 include four plates, which are side plates 46A to 46D respectively corresponding to each side of the rectangular bottom plate 42. The side plate 46A and the side plate 46C face each other, and the side plate 46B and the side plate 46D face each other. That is, the photographing box 40 includes two pairs of opposing side plates 46.

[0050] As shown in FIG. 4, among the four side plates 46, the side plate 46A is a door that can be opened outward. A grip portion 43 is provided on the side plate 46A. By hooking a finger on the grip portion 43 and pulling it toward the user, the side plate 46A opens outward as shown from (i) to (ii) in FIG. 4. The side plate 46A can be opened at a sufficient angle to accommodate the calibration member 20 (the color-developing member 30) inside, for example, 90 degrees or more. Note that the side plate 46A of the present embodiment is an example of the insertion portion of the present disclosure. In the example shown in FIG. 4, the case where the side plate 46A is the door has been described, but which of the four side plates 46 serves as the door is not limited. Further, instead of the side plate 46, the top plate 44 may serve as the door. Furthermore, the shape of the door is not limited to the form shown in FIG. 4. For example, the door may be a double door that opens to the left and right, a door that opens in a folded manner, or a shutter-shaped door.

[0051] A window 45 is provided in the top plate 44, which is located on the upper side of the side plate 46 and covers the top of the color-emitting member 30. The inside of the shooting box 40 can be seen through the window 45. When photographing the color-emitting member 30, a camera 11 (smartphone 10) is placed on the top plate 44. The camera 11 photographs the color-emitting member 30 housed inside through the window 45. The window 45 may be hollow or may have a transparent material such as glass fitted into it. The top plate 44 in this embodiment is an example of the top plate portion of this disclosure.

[0052] As shown in Figure 5, the smartphone 10 (color-emitting member 30) is held on the bottom plate 42. Note that in Figure 5, the side plate 46A is omitted from the illustration in order to show the inside of the shooting box 40. Also, the illustration of the calibration member 20 and the color-emitting member 30 is simplified, and the illustration of the transparent member 34 is omitted. Note that the bottom plate 42 in this embodiment is an example of the holding member of this disclosure.

[0053] It is preferable that the base plate 42 holds the calibration member 20 in a fixed position so that it does not move while being held. For example, the base plate 42 may have fasteners that fix the four corners of the calibration member 20, and the calibration member 20 may be held by fixing the calibration member 20 with these fasteners.

[0054] The bottom plate 42, top plate 44, and side plates 46 have black surfaces facing the color-emitting member 30. In other words, the inner housing portion of the shooting box 40 is black. By making the inside of the shooting box 40 black in this way, specific reflection and absorption due to wavelength can be suppressed. The bottom plate 42, top plate 44, and side plates 46 themselves may be black, or their inner surfaces may be made black by painting or other means. Specifically, for example, if the bottom plate 42, top plate 44, and side plates 46 are made of metal or resin, it is preferable to apply a matte black paint or black anodizing treatment. Alternatively, a black resin plate may be used for the side plate 46. Furthermore, for each of the bottom plate 42, top plate 44, and side plates 46, at least the inner surface of the shooting box 40 may be made of nonwoven fabric or other cloth. In this case, the choice of material and combination of materials is arbitrary, as long as it is black and does not have specific reflection and absorption characteristics, and a combination of material and paint may also be used.

[0055] Furthermore, as shown in Figure 5, the shooting box 40 of this embodiment is equipped with a light source 50 supported in a manner that extends in a direction surrounding the color-generating member 30, in at least a portion of the surface of the side plate 46 on the side facing the color-generating member 30. Specifically, the light source 50A is provided on the side plate 46B in a manner that extends parallel to the bottom plate 42 and in the X-axis direction. The light source 50B is provided on the side plate 46D in a manner that extends parallel to the bottom plate 42 and in the X-axis direction. The side plates 46B and 46D of this embodiment are examples of the support members of this disclosure.

[0056] Light sources 50A and 50B are arranged facing each other. The light source 50 is preferably one with high color rendering and minimal change over time. Examples of such light sources 50 include LED (Light Emitting Diode) tape lights and bar-type LEDs. Note that each of the light sources 50A and 50B may contain multiple lights. For example, in the example shown in Figure 5, the case is shown where each of the light sources 50A and 50B extends from end to end on each of the side plates 46B and 46D, but each of the light sources 50A and 50B may contain multiple lights shorter than half the length of the side plate 46. Furthermore, when each of the light sources 50A and 50B contains multiple lights in this way, there may be spacing between the lights.

[0057] The switch for turning the light source 50 on and off may be located inside or outside the shooting box 40. Furthermore, it is preferable that the light source 50 be detachable from the side panels 46 (46B, 46D).

[0058] As described above, in the shooting box 40 of this embodiment, since the light source 50 is provided on the side plate 46, the calibration member 20 and the color development member 30 can be illuminated with shooting light from the side.

[0059] In this embodiment, the shooting box 40 is positioned so that the light source 50 does not appear in the captured image 8. Specifically, the height H from the bottom plate 42 on which the light source 50 is mounted is determined as follows for the side plates 46, B, and 46D.

[0060] When light emitted from the light source 50 and specularly reflected off the surface of the calibration member 20 (specular reflected light) is incident on the camera 11, the light source 50 is reflected in the captured image 8. As shown in Figure 6, with the light source 50-1 located at a height h1 from the bottom plate 42, the specularly reflected light from the light incident on the surface of the end of the calibration member 20 is incident on the camera 11. Therefore, the light source 50-1 is reflected in the captured image 8.

[0061] As shown in Figure 6, since the incident angle a of the light source 50-1 is the same as the incident angle a determined according to the normal L at the end of the calibration member 20 and the field of view of the camera 11, specular reflected light is incident on the camera 11 as described above.

[0062] If the incident angle of the irradiated light is greater than the incident angle a, the reflected light reflected from the surface of the calibration member 20 will not enter the camera 11. In the example shown in Figure 6, the incident angle b of the light source 50-2 is greater than the incident angle a, so specular reflected light will not enter the camera 11, and the light source 50-2 will not be reflected in the captured image 8. The height h2 of the light source 50-2 is less (lower) than the height h1 of the light source 50-1. In this way, when the light source 50 is positioned at a height lower than h1 from the base plate 42, it is possible to suppress the reflection of the light source 50 in the captured image 8.

[0063] Furthermore, in the case of the light source 50-3 shown in Figure 6, the incident angle c is greater than the incident angle a, so it is possible to suppress the reflection of the light source 50-3 in the captured image 8. However, if the height h3 is too low, the illumination may be insufficient. Also, if the height h3 is too low, it may be affected by unevenness in brightness caused by the waviness of the calibration member 20, etc. In other words, the lower limit of the height H at which the light source 50 is installed is determined according to the illumination for the color-generating member 30, etc. Specifically, the lower limit of the height H should be determined according to the light intensity of the light source 50, the distance between the light source 50 and the color-generating member 30, etc. For example, if the height h3 of the light source 50-3 is below the lower limit, the illumination from the light source 50-3 will be insufficient, so it is not desirable to install the light source 50 at this position. Therefore, it is preferable that the height H of the light source 50 is greater than or equal to the above lower limit and less than the height h1.

[0064] Furthermore, the color temperature of the photographic light emitted from the light source 50 is angle-dependent. Therefore, if the photographic light is emitted from the side by the light source 50, the accuracy may deteriorate due to the positional relationship between the color-emitting member 30 and the light source 50. In particular, since the color temperature of the light source 50 is different from that of typical ceiling lighting, a decrease in color temperature results in a reddish tint, resulting in a photographic image 8 that is redder than the original color, and it may not be possible to accurately estimate the pressure of the color-emitting member 30. In particular, since the calibration member 20 (color-emitting member 30) is housed inside the photographic box 40, the distance between the light source 50 and the color-emitting member 30 is relatively short. Therefore, the effect of angle dependence becomes large. For this reason, the color temperature range of the light source 50 is preferably 5000K to 6500K. Moreover, it is even more preferable to use a light source with high color rendering as the light source 50. A light source with high color rendering is a light source whose average color rendering index Ra, as defined in the color rendering evaluation method for light sources specified in JIS Z 8726-1990, is 80 or higher.

[0065] Furthermore, it is preferable that the angle between the normal to the light source 50 and the line connecting the light source 50 and the surface of the calibration member 20 be 40 degrees or less, and more preferably 15 degrees or less. Specifically, in the example shown in Figure 7, if the angle d at light source 50-4, the angle e at light source 50-5, and the angle f at light source 50-6 are 40 degrees or less, the influence of angle dependence can be suppressed, and an appropriate color temperature can be obtained. The shooting box 40 may be configured to allow the light source 50 to be positioned at an angle that is tilted to obtain an appropriate color temperature, or the angle of the light source 50 may be adjustable.

[0066] The position (height H) of the light source 50 in the shooting box 40 of this embodiment is determined from the viewpoint of reflection, illuminance, and color temperature, as described above. Specifically, the position (height H) of the light source 50 should be determined in consideration of the size (area) of the calibration member 20 and the color-generating member 30, the size (area) of the bottom plate 42, etc., so as to satisfy the above conditions. For example, if the height of the shooting box 40 (length in the Z-axis direction of the side plate 46) is 400 mm, the length in the X-axis direction is 400 mm, and the length in the Y-axis direction is 60 mm, the height H of the light source 50 should be set to 125 mm.

[0067] In this embodiment, after holding the color-generating member 30 (calibration member 20) on the bottom plate 42 of the shooting box 40, the side plate 46A, which is a door, is closed and the light source 50 is turned on, and the color-generating member 30 is photographed through the window 45 from the camera 11 installed on the top plate 44. This results in a photographed image 8 of the color-generating member 30 (calibration member 20).

[0068] Next, the smartphone 10 of this embodiment will be described in detail. First, an example of the hardware configuration of the smartphone 10 will be described with reference to Figure 8. As shown in Figure 8, the smartphone 10 includes a CPU (Central Processing Unit) 80, a non-volatile storage unit 82, and a memory 81 as a temporary storage area. The smartphone 10 also includes a display 84 such as a liquid crystal display, an input unit 88, a network interface 86, and a camera 11. The CPU 80, storage unit 82, memory 81, display 84, input unit 88, network interface 86, and camera 11 are connected to each other via a bus 89 such as a system bus and a control bus, enabling the exchange of various types of information.

[0069] The storage unit 82 is implemented by a storage medium such as an HDD (Hard Disk Drive), SSD (Solid State Drive), and flash memory. The storage unit 82 stores the measurement program 83. The CPU 80 reads the measurement program 83 from the storage unit 82, expands it into memory 81, and executes the expanded measurement program 83. The CPU 80 is an example of the processor of this disclosure, and the measurement program 83 is an example of the energy measurement program of this disclosure.

[0070] The input unit 88 is for receiving user input and can be, for example, a touch panel, buttons, a keyboard, or a mouse. As an example, the camera 11 in this embodiment employs a touch panel display that integrates the display 84 and the input unit 88. The network interface 86 communicates via wired or wireless connection with the server 4 and other external devices (not shown). The camera 11 has multiple sensors with different spectral sensitivities, and under the control of the CPU 80, the sensors capture images of subjects and output the image signal of the captured image 8.

[0071] Next, an example of the functional configuration of the smartphone 10 will be described with reference to Figure 9. As shown in Figure 9, the smartphone 10 includes an acquisition unit 90, a correction unit 92, an output unit 94, and a control unit 96. When the CPU 80 executes the measurement program 83, the CPU 80 functions as the respective functional units of the acquisition unit 90, correction unit 92, output unit 94, and control unit 96.

[0072] The acquisition unit 90 acquires an image 8 captured by the camera 11, which includes an image representing the calibration member 20 (hereinafter referred to as the "calibration member image") and an image of the color-developing member 30.

[0073] The correction unit 92 extracts an image representing the frame 21 (hereinafter referred to as the "frame image") from the captured image 8, and corrects at least one of the distortion, tilt, and size of the captured image 8 based on the shape of the extracted frame image. As for the method of extracting the frame image, a known method using edge extraction processing in the image can be appropriately applied. Specifically, if the frame 21 is rectangular, the frame image is also rectangular, and the correction unit 92 corrects the distortion, tilt, and size of the captured image 8 by performing projection transformation and affine transformation, etc., so that the four corners of the frame image extracted from the captured image 8 are each 90 degrees.

[0074] Furthermore, the correction unit 92 performs calibration of the captured image 8 acquired by the acquisition unit 90 using images representing the patches 25 included in the captured image 8 (hereinafter referred to as "patch images"). Specifically, the correction unit 92 performs calibration of the color of the color-generating member image included in the captured image 8 (for example, at least one of hue and density) based on the colors of the patch images of the patches 25 included in the first patch groups 22A and 22B and the second patch groups 24A and 24, respectively, included in the captured image 8. Known methods can be appropriately applied as calibration methods. For example, a reference color for each patch 25 included in the calibration member 20 is stored in the storage unit 82 in advance, and the correction unit 92 adjusts the color of the captured image 8 to match the respective reference color of each of the multiple patch images included in the captured image 8.

[0075] Furthermore, as described above, each of the first patch groups 22A and 22B, and the second patch groups 24A and 24B, may each contain a patch 25 of the same color. In this case, due to the influence of the shooting environment, such as the lighting environment in which the shooting takes place, the characteristics of the camera 11, the shooting angle, and the shooting distance, patches 25 that are originally formed with the same color may appear as different colors on the captured image 8. For example, the correction unit 92 may adjust the color of the captured image 8 so that the average color of the patch images corresponding to the patches 25 formed with the same color matches the reference color. Alternatively, the correction unit 92 may adjust the color of the captured image 8 so that the patch image color that is closest to the reference color among the patches 25 formed with the same color matches the reference color.

[0076] The correction unit 92 may perform calibration using some of the patch images of the multiple patches 25 included in each of the first patch groups 22A and 22B and the second patch groups 24A and 24B.

[0077] For example, the correction unit 92 may vary the patch 25 used for calibration according to the type of color-developing member 30. For example, Prescale, as an example of a color-developing member 30, is manufactured in multiple varieties with different measurable pressure ranges, such as for low pressure, medium pressure, and high pressure. Also, as mentioned above, in addition to Prescale, Thermoscale and UVscale can also be used as the color-developing member 30.

[0078] Therefore, the correction unit 92 may perform calibration using a predetermined selection of patch images of patches 25 from among the patch images of multiple patches 25 included in the first patch groups 22A and 22B and the second patch groups 24A and 24B, according to the type of color-developing member 30 corresponding to the color-developing member image. The correspondence between the type of color-developing member 30 and the patch 25 used for calibration may be stored in the storage unit 82 in advance, for example. The type of color-developing member 30 that has been photographed may be input by the user via the input unit 88, or an identification code indicating the type of color-developing member 30 may be attached to the color-developing member 30, and the correction unit 92 may identify it by reading the identification code from the photographed image 8.

[0079] In this way, the correction unit 92 corrects the distortion, tilt, size, and color of the captured image 8, thereby correcting the influence of the shooting environment, such as the lighting environment, characteristics of the camera 11, shooting angle, and shooting distance, which may occur when the user takes a picture.

[0080] The derivation unit 94 derives the amount of energy applied to the color-developing member 30 based on the color of the color-developing member image after calibration by the correction unit 92. Specifically, the relationship between the amount of energy applied to the color-developing member 30 and the color of the color-developing member 30 may be predetermined and stored in the storage unit 82, and the derivation unit 94 may use this data to convert the color of the color-developing member image included in the captured image 8 into an energy amount. The data determining the relationship between the amount of energy applied to the color-developing member 30 and the color of the color-developing member 30 may be prepared in advance for each type of color-developing member 30 and stored in the storage unit 82.

[0081] Furthermore, the derivation unit 94 may derive various indicators related to the amount of energy applied to the color-developing member 30. These indicators include, for example, the energy distribution obtained by deriving the amount of energy for each pixel of the color-developed image corresponding to the color-developed region of the color-developing member 30 (hereinafter referred to as the "color-developed region"), as well as representative values ​​such as the maximum, minimum, average, and median values ​​of the energy amount in the color-developed region. Other indicators include, for example, the area of ​​the color-developed region, the percentage of the area within the color-developed region where the energy amount falls within a predetermined range, the uniformity of the energy amount in the color-developed region, and the load of the color-developed region (product of the area of ​​the color-developed region and the average value of the energy amount). Another indicator is, for example, the degree of agreement or deviation from the standard when a standard is predetermined for the degree of color development (i.e., energy amount and energy distribution) of the color-developing member 30.

[0082] The control unit 96 controls the display 84 to display the captured image 8, which has been corrected for distortion, tilt, size, and color by the correction unit 92, and various indicators related to the amount of energy derived by the derivation unit 94. Figure 10 shows an example of screen D displayed on the display 84 by the control unit 96. Screen D displays the color-generating member image 31 in the captured image 8 and various indicators related to the amount of energy derived from the color-generating member image 31.

[0083] As shown in screen D, the control unit 96 may extract the color-developing member image 31 from the captured image 8 and control it to display it on the display 84. Note that in screen D shown in Figure 10, "pressure area" means the area of ​​the color-developing region. "Average pressure" means the average value of the energy amount of the color-developing region. "Load" means the product of the pressure area and the average pressure. "Uniformity of pressure value" means the uniformity of the pressure value of the color-developing region.

[0084] Furthermore, the control unit 96 may accept input of supplementary information related to the captured image 8. On screen D, as an example of supplementary information related to the captured image 8, the type of color-developing member 30, pressure type, room temperature, and humidity are displayed, and a pull-down menu P for accepting input of these is displayed. The "pressure type" may include instantaneous pressure, which indicates the magnitude of the pressure instantaneously applied to the Prescale, and sustained pressure, which indicates the time integral of the magnitude of the pressure continuously applied to the Prescale. Other examples of supplementary information include identification information of the calibration member 20, the color-developing member 30, the user who applied energy to the color-developing member 30, and the user who took a photograph of the color-developing member 30, the user's evaluation result regarding the amount of energy, and various inspection conditions.

[0085] Furthermore, the control unit 96 transmits at least one of the following to the server 4 via the network interface 86: the captured image 8 before correction by the correction unit 92, the captured image 8 after correction, the color-developing member image 31, and the color-developing member image 31 after correction. The control unit 96 also transmits various indicators related to the amount of energy derived by the derivation unit 94, and the received supplementary information to the server 4. The server 4 stores the information received from the smartphone 10 (control unit 96) in the database 6, associating it with the captured image 8.

[0086] Next, the operation of the smartphone 10 according to this embodiment will be explained with reference to Figure 11. In the smartphone 10, the CPU 80 executes the measurement program 83, thereby executing the measurement process shown in Figure 11. The measurement process is executed, for example, when the user gives an instruction to start execution via the input unit 88.

[0087] In step S100, the acquisition unit 90 acquires a captured image 8, which is captured by the camera 11 and includes a calibration member image of the calibration member 20 and a color member image 31 of the color member 30. In the next step S102, the correction unit 92 extracts a frame image of the frame 21 from the captured image 8 acquired in step S100, and corrects at least one of the distortion, tilt, and size of the captured image 8 based on the shape of the extracted frame image. In the next step S104, the correction unit 92 uses the patch image included in the captured image 8 corrected in step S102 to perform color calibration on the captured image 8 (particularly the color member image 31 included in the captured image 8).

[0088] In the next step S106, the derivation unit 94 derives the amount of energy applied to the color-developing member 30 based on the color of the color-developing member image 31 calibrated in step S104. In the next step S108, the control unit 96 controls the display 84 to display the color-developing member image 31 calibrated in step S104 and the amount of energy derived in step S106. As a result of this control, the screen D shown in Figure 10 is displayed on the display 84. When the processing in step S108 is completed, the information processing shown in Figure 11 is completed.

[0089] As described above, the shooting box 40 of this embodiment is provided with side plates 46B and 46D that are located around at least a portion of the color-generating member 30, which develops color with a density distribution corresponding to the amount of energy applied, and that extend in the direction of the camera 11 that photographs the color-generating member 30. The shooting box 40 is also provided with light sources 50A and 50B that are supported in a manner that extends in a direction surrounding the color-generating member 30 in at least a portion of the surface of the side plates 46B and 46D on the side of the color-generating member 30, and that irradiate the color-generating member 30 with light.

[0090] With the shooting box 40, the light source 50 can irradiate the color-emitting member 30 with light (photographic light) from the side of the color-emitting member 30. Therefore, with the shooting box 40, when photographing the color-emitting member 30 for energy measurement, it is possible to obtain a photographed image 8 in which the reflection of the light source 50 is suppressed. As a result, the decrease in the accuracy of pressure measurement can be suppressed by being in the shooting box 40.

[0091] Furthermore, the imaging support device of this disclosure is not limited to the imaging box 40 described above, and may include any support member provided around at least a portion of the color-generating member 30 that is capable of supporting the light source 50 in a manner that extends in a direction surrounding the color-generating member 30.

[0092] For example, at least one of the bottom plate 42 and the top plate 44 in the shooting box 40 does not need to be provided.

[0093] Furthermore, the above-described shooting box 40 is equipped with two pairs of opposing side panels 46, and a light source 50 is provided on one of these pairs (side panels 46B and 46D), but a light source 50 may be provided on both pairs. In other words, a light source 50 may be provided on all of the side panels 46.

[0094] Furthermore, although the above describes a configuration in which the calibration member 20 (color-developing member 30) is inserted into the imaging box 40 with the side plate 46A open, the method of inserting the calibration member 20 (color-developing member 30) into the imaging box 40 is not limited. For example, if the bottom plate 42 is retractable, the calibration member 20 (color-developing member 30) may be held on the retracted bottom plate 42, and the bottom plate 42 may be inserted into the imaging box 40. Figure 12 shows an example of the appearance of an imaging box 40 in which the bottom plate 42 is retractable. The imaging box 40 shown in Figure 12 is provided with a drawer 47 including the bottom plate 42. The drawer 47 is provided with a gripping portion 48, and by placing a finger on the gripping portion 48 and pulling it towards the front, the bottom plate 42 can be pulled out as shown in Figure 12. According to the imaging box 40 shown in Figure 12, the calibration member 20 (color-developing member 30) can be placed in the drawer 47 that is pulled out towards the front, and the calibration member 20 (color-developing member 30) can be inserted into the imaging box 40 by returning the drawer 47 to its original position. In Figure 12, the case where the lower part of the side plate 46B is pulled out towards the front is shown, but it may also be the case where the lower part of a side plate 46 other than the side plate 46B is pulled out. In the example shown in Figure 12, the drawer 47 is an example of the insertion part of this disclosure.

[0095] Furthermore, when the color-developing member 30 (calibration member 20) is not being photographed, the side panels 46 of the shooting box 40 may be folded, or the shooting box 40 may be disassembled. In other words, the shooting box 40 may be deformable to a size smaller than the box shape used during shooting. By being able to deform to a compact size in this way, the shooting box 40 can be easily carried and storage space can be reduced.

[0096] Furthermore, although the width of the side plate 46, which is a support member for the light source 50, was set to be the same as the length over which the light source 50 extends, the width of the side plate 46 is not limited. In other words, the width of the support member for the light source 50 is not limited. For example, a columnar support member may be used. In this case, the length over which the light source 50 extends may be longer than the width of the support member.

[0097] Furthermore, the above describes a configuration in which the camera 11 is placed on the top plate 44 of the shooting box 40, and the color-generating member 30 (calibration member 20) is photographed through a window 45 provided on the top plate 44. However, the location where the camera 11 is placed is not limited to this configuration. For example, the camera 11 may be placed inside the shooting box 40. In this case, the camera 11 may be dedicated to photographing the color-generating member 30, or a general-purpose camera may be used. Also, the structure for placing the camera 11 inside the shooting box 40 is not limited. In this case, the window 45 does not need to be provided on the top plate 44. Moreover, when the camera 11 is placed inside the shooting box 40, the height of the shooting box 40 (side plate 46) will increase by the amount of the camera 11 placed inside.

[0098] Furthermore, while the above describes an example of the imaging device of this disclosure in which a camera 11 provided on a smartphone 10 is applied, the imaging device is not limited to the camera 11 provided on a smartphone 10. For example, a digital camera or the like, provided separately from the smartphone 10, may be used as the imaging device. Alternatively, for example, a USB camera connected to a personal computer via a USB (Universal Serial Bus) cable may be used as the imaging device. Furthermore, while the above describes an example of the energy measuring device of this disclosure in which a smartphone 10 is applied, the energy measuring device is not limited to a smartphone 10. For example, a tablet terminal, a wearable terminal, and a personal computer may be used as the energy measuring device. Furthermore, while the above describes an integrated configuration of the imaging device and the energy measuring device as a smartphone 10, the imaging device and the energy measuring device may be separate.

[0099] It should be noted that the configuration and operation of the energy measurement system 1, calibration member 20, shooting box 40, and smartphone 10, etc., described in the above embodiment are merely examples and can be modified as needed without departing from the spirit of the present invention. It should also be noted that the above embodiments may be combined as appropriate.

[0100] Furthermore, in this embodiment, each process is executed on any computer. Alternatively, any computer may execute these processes using a processor as hardware, a program as software, or a combination thereof. In that case, the processor is configured to work in cooperation with the program to execute the various processes in this embodiment, and can function as a unit or means in this embodiment. The execution order of the processes by the processor is not limited to the order described and may be changed as appropriate. Any computer may be a general-purpose computer, a computer designed for a specific purpose, a workstation, or any other system capable of executing each process.

[0101] A processor may consist of one or more hardware components, and the type of hardware is not limited. For example, a processor may consist of programmable logic devices such as a CPU (Central Processing Unit), MPU (Micro Processing Unit), FPGA (Field Programmable Gate Array), dedicated circuits for performing specific processing such as an ASIC (Application Specific Integrated Circuit), a GPU (Graphic Processing Unit), or an NPU (Neural Processing Unit). Furthermore, the type of hardware may be a combination of different types of hardware. When multiple hardware components are configured to execute one or more processes of a processor, these components may reside in physically separate devices or in the same device. Furthermore, in any embodiment, the order of the processes performed by the processor is not limited to the order described above and may be changed as appropriate. The hardware components are composed of electrical circuits (circuits) and the like, which are combinations of circuit elements such as semiconductor elements.

[0102] Furthermore, the program may be firmware or software such as microcode. Alternatively, the program may be, for example, a set of program modules, each function of which may be implemented by a processor configured to perform its respective function. The program may be program code or multiple code segments stored on one or more non-temporary computer-readable media (e.g., storage media or other storage). The program may be divided and stored on multiple non-temporary computer-readable media located on physically separate devices. Program code or code segments may represent any combination of procedures, functions, subprograms, routines, subroutines, modules, software packages, classes, or instructions, data structures, or program statements. Program code or code segments may be connected to other code segments or hardware circuits by sending and receiving information, data, arguments, parameters, or memory contents.

[0103] Furthermore, although the above embodiment describes a configuration in which the measurement program 83 is pre-stored (installed) in the storage unit 82, the invention is not limited to this configuration. The measurement program 83 may be provided in the form of a recording medium such as a CD-ROM (Compact Disc Read Only Memory), DVD-ROM (Digital Versatile Disc Read Only Memory), or USB memory. Alternatively, the measurement program 83 may be provided in the form of a download from an external device via a network.

[0104] Furthermore, the technology disclosed herein extends to all program products. Program products include all forms of products for providing programs. For example, program products include programs provided via networks such as the Internet, and non-temporary computer-readable recording media such as CD-ROMs, DVDs, and USB memory sticks on which programs are stored.

[0105] The following additional information is disclosed regarding the above-described embodiments.

[0106] (Note 1) A photographic support device comprising: a support member provided around at least a portion of a color-producing member that produces color in a density distribution corresponding to the amount of energy applied, and extending in the direction of a photographic device that photographs the color-producing member; and a light source supported in at least a portion of the area of ​​the surface of the support member on the side of the color-producing member, in a manner that extends in a direction surrounding the color-producing member, and irradiating the color-producing member with light.
