Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of a biological imaging system, a biological imaging device, a biological imaging method, and a recording medium will be described with reference to the drawings.

[0012] <First Embodiment> The biological imaging system according to the first embodiment will be described with reference to FIGS. 1 to 3.

[0013] (Hardware Configuration) First, the hardware configuration of the biological imaging system according to the first embodiment will be described with reference to FIG. 1. FIG. 1 is a block diagram showing the hardware configuration of the biological imaging system according to the first embodiment.

[0014] As shown in Figure 1, the bioimaging system 10 according to the first embodiment includes a processor 11, RAM (Random Access Memory) 12, ROM (Read Only Memory) 13, and a storage device 14. The bioimaging system 10 may further include an input device 15 and an output device 16. The bioimaging system 10 may also include a camera 18 and a drive device 19. The processor 11, RAM 12, ROM 13, storage device 14, input device 15, output device 16, camera 18, and drive device 19 are connected via a data bus 17.

[0015] The processor 11 reads a computer program. For example, the processor 11 is configured to read a computer program stored in at least one of the RAM 12, ROM 13, and storage device 14. Alternatively, the processor 11 may read a computer program stored in a computer-readable recording medium using a recording medium reading device (not shown). The processor 11 may also obtain (i.e., read) a computer program from a device (not shown) located outside the biological imaging system 10 via a network interface. The processor 11 controls the RAM 12, storage device 14, input device 15, and output device 16 by executing the read computer program. In this embodiment in particular, when the processor 11 executes the read computer program, a functional block for guiding the position of a living organism and capturing an image is realized within the processor 11.

[0016] The processor 11 may be configured as, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), a DSP (Demand-Side Platform), or an ASIC (Application Specific Integrated Circuit). The processor 11 may consist of one of these, or it may be configured to use multiple of them in parallel.

[0017] RAM12 temporarily stores computer programs executed by processor 11. RAM12 also temporarily stores data that processor 11 uses temporarily while it is executing computer programs. RAM12 may be, for example, D-RAM (Dynamic RAM).

[0018] ROM 13 stores computer programs executed by processor 11. ROM 13 may also store other static data. ROM 13 may be, for example, a P-ROM (Programmable ROM).

[0019] The storage device 14 stores data that the bioimaging system 10 stores long-term. The storage device 14 may also operate as a temporary storage device for the processor 11. The storage device 14 may include, for example, at least one of a hard disk drive, a magneto-optical disk drive, an SSD (Solid State Drive), and a disk array device.

[0020] The input device 15 is a device that receives input instructions from the user of the bio-imaging system 10. The input device 15 may include, for example, at least one of a keyboard, a mouse, and a touch panel. The input device 15 may be configured as a portable terminal such as a smartphone or tablet.

[0021] The output device 16 is a device that outputs information related to the bioimaging system 10 to the outside. For example, the output device 16 may be a display device (e.g., a display) capable of displaying information related to the bioimaging system 10. Alternatively, the output device 16 may be a speaker or the like capable of outputting audio information related to the bioimaging system 10. The output device 16 may be configured as a mobile terminal such as a smartphone or tablet.

[0022] Camera 18 is a camera capable of capturing images of living organisms (for example, images of fingerprints (epidermis and dermis), palm prints, veins, etc.). Note that "living organism" here is not limited to humans, but may include animals such as dogs and snakes. Camera 18 may be a camera that captures still images or a camera that captures moving images. Camera 18 may be configured as a visible light camera or a near-infrared camera. Furthermore, camera 18 may be configured as an optical scanner.

[0023] The drive unit 19 is a device that drives various parts of the bioimaging system 10. The operation of the drive unit 19 may be controlled, for example, by the processor 11. The drive unit 19 may be configured to include, for example, actuators. In addition, the drive unit 19 according to this embodiment may have a function for filling with liquid. In this case, the drive unit 19 may include a housing, cover, container, etc. that forms a region for filling with liquid. Furthermore, the drive unit 19 according to this embodiment may be configured to drive devices (for example, a light source, a blower, etc.) for performing guidance operations using liquid (details will be described later) and operations associated therewith.

[0024] Although Figure 1 shows an example of a bioimaging system 10 comprising multiple devices, all or some of these functions may be realized by a single device (biomedical imaging device). This bioimaging device may, for example, consist only of the processor 11, RAM 12, and ROM 13 described above, with other components (i.e., storage device 14, input device 15, output device 16, camera 18, and drive device 19) provided by, for example, external devices connected to the bioimaging device. Furthermore, the bioimaging device may have some of its computing functions realized by external devices (e.g., external servers or cloud services).

[0025] (Functional configuration) Next, the functional configuration of the bioimaging system 10 according to the first embodiment will be described with reference to Figure 2. Figure 2 is a block diagram showing the functional configuration of the bioimaging system according to the first embodiment.

[0026] In Figure 2, the bioimaging system 10 according to the first embodiment is configured as a system for capturing images of living organisms. The bioimaging system 10 may be configured, for example, as a system for capturing images used for biometric authentication. The bioimaging system 10 is configured to include a liquid filling unit 110, a bio-guiding unit 120, and an imaging unit 130 as components for realizing its function.

[0027] The liquid filling unit 110 is configured to include, for example, the drive device 19 (see Figure 1) described above, and is configured to fill the imaging range of the imaging unit 130 with liquid. The liquid filling unit 110 may fill the liquid to cover the entire imaging range of the imaging unit 130, or it may fill the liquid to cover only a part of the imaging range. The liquid filled by the liquid filling unit 110 is a liquid that is safe to come into contact with living organisms, such as water or alcohol. The method of filling the liquid by the liquid filling unit 110 will be specifically described in other embodiments described later.

[0028] The biological guide unit 120 is configured to include, for example, the drive device 19 (see Figure 1) described above, and is configured to guide the position of the living organism (i.e., the imaging target) using the liquid filled by the liquid filling unit 110. Specifically, the biological guide unit 120 is configured to guide the living organism to a location suitable for imaging by the imaging unit 130. The guidance method by the biological guide unit 120 will be specifically described in other embodiments described later.

[0029] The imaging unit 130 is configured to include, for example, the camera 18 (see Figure 1) described above, and is capable of imaging a living organism guided by the biological guidance unit 120. The imaging unit 130 has, for example, a fixed imaging range and is configured to image a living organism guided into the imaging range by the biological guidance unit 120. The imaging unit 130 may be configured as, for example, a non-contact type fingerprint scanner, palm print scanner, or vein scanner. In the following, we will proceed with an example in which the imaging unit 130 is configured as a fingerprint scanner (in other embodiments described later, an example in which the imaging unit 130 is configured as a fingerprint scanner will also be described, but the configuration of the imaging unit 130 is not limited to a fingerprint scanner).

[0030] (Flow of operations) Next, the operation flow of the bioimaging system 10 according to the first embodiment will be described with reference to Figure 3. Figure 3 is a flowchart showing the operation flow of the bioimaging system according to the first embodiment.

[0031] As shown in Figure 3, when the bioimaging system 10 according to the first embodiment operates, it first determines whether or not to start imaging of a living organism (step S101). Whether or not to start imaging may be determined, for example, in response to user operation. For example, it may be determined to start imaging when the user presses a button to start imaging. Alternatively, it may be determined whether or not to start imaging by detecting the presence of a living organism to be imaged. For example, it may be determined to start imaging when the device detects the approach of a user using a sensor or the like. If it is determined not to start imaging (step S101: NO), the subsequent processing is carried out and the series of operations ends.

[0032] On the other hand, if it is determined that imaging should be started (step S102: YES), the liquid filling unit 110 fills the imaging range of the imaging unit 130 with liquid (step S102). The liquid filling unit 110 may start filling the liquid before it is determined that imaging should be started. For example, if imaging is performed at a relatively high frequency, the liquid may be filled in advance. Alternatively, in order to complete the liquid filling early, the liquid may be filled in advance (for example, half the amount may be filled in advance).

[0033] Next, the biological guide unit 120 uses the liquid filled in the liquid filling unit 110 to guide the position where the biological body will be placed (step S103). After that, the imaging unit 130 images the biological body guided by the biological guide unit 120 (step S104). The imaging unit 130 may image the same biological body multiple times.

[0034] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the first embodiment will be described.

[0035] As explained in Figures 1 to 3, in the bioimaging system 10 according to the first embodiment, the imaging range of the imaging unit 130 is filled with liquid, and the position of the living organism is guided by this liquid. In this way, it is possible to guide the living organism, which is the target of imaging, to a position suitable for imaging and to capture an image of the living organism. Such technical effects are particularly evident when the range in which the imaging unit 130 can capture a suitable image is narrow (for example, when the focus range or field of view is narrow). They are also particularly evident when it is difficult to communicate the position of the living organism (for example, when it is required to place the living organism in a predetermined space in order to perform imaging with a non-contact scanner).

[0036] <Second Embodiment> The bioimaging system 10 according to the second embodiment will be described with reference to Figures 4 to 6. Note that the second embodiment differs from the first embodiment described above only in some configurations and operations; other parts may be identical to the first embodiment. Therefore, the following will describe in detail the parts that differ from the first embodiment already described, and will omit explanations of other overlapping parts as appropriate.

[0037] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the second embodiment will be described with reference to Figures 4 and 5. Figure 4 is a side view showing the configuration and operation of the bioimaging system according to the second embodiment. Figure 5 is a top view showing an example of a mark on a container in the bioimaging system according to the second embodiment.

[0038] As shown in Figure 4, the bioimaging system 10 according to the second embodiment is configured such that the liquid filling section 110 (see Figure 2) includes a container 20 for holding liquid 30. The container 20 is made of, for example, transparent resin or glass, and the camera 18, positioned below the container 20, is configured to capture images by passing through the container 20 and the liquid 30. The container 20 may also have a function to maintain a constant temperature of the filled liquid 30.

[0039] The biological guide unit 120 is configured to guide the position of a living organism based on the amount of liquid 30 stored in the container 20. Specifically, the biological guide unit 120 determines the amount of liquid 30 stored in the container 20 (in other words, the height of the liquid surface) and guides the position of the living organism based on that liquid surface. For example, when capturing a fingerprint image, as shown in Figure 4, positioning the finger 50 so that it is submerged in the liquid surface will result in a position where an appropriate image can be captured. The amount of liquid 30 may be set according to the imaging range and installation position of the camera 18, as well as camera parameters, etc. Alternatively, the camera parameters may be adjusted according to the amount of liquid 30.

[0040] As shown in Figure 5, the container 20 may be provided with marks to guide the lateral (horizontal) position of the finger 50. Specifically, as shown in Figure 5(a), a frame line may be provided on the bottom of the container 20 to indicate the area within and outside the imaging range. Alternatively, as shown in Figure 5(b), a frame line that shows the outline of the finger may be provided. These marks are positioned so that when the finger 50 is placed within the frame line, the finger is within the imaging range of the camera 18. Furthermore, the marks themselves are positioned so as not to interfere with imaging.

[0041] (Example of a sign used when providing directions) Next, with reference to Figure 6, an example of the display when guidance is provided by the bio-imaging system 10 according to the second embodiment will be described. Figure 6 is a plan view showing an example of the display by the bio-imaging system according to the second embodiment.

[0042] As shown in Figure 6, the bioimaging system 10 according to the second embodiment may display a message prompting the user to immerse their finger 50 in the liquid 30. Specifically, as shown in Figure 6(a), a message such as "Place your fingertip on the liquid surface" may be displayed. Furthermore, after the finger 50 is actually placed, additional messages may be displayed depending on its position. For example, if the finger 50 is too high (the finger 50 is placed on the liquid surface less than expected), a message such as "Place your finger a little deeper" may be displayed, as shown in Figure 6(b). If the finger 50 is too low (the finger 50 is placed on the liquid surface deeper than expected), a message such as "Place your finger a little shallower" may be displayed. Also, if the finger 50 is at an appropriate height, a message such as "Keep it at that height" may be displayed. Such displays may be provided, for example, by a display provided by the output device 16.

[0043] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the second embodiment will be described.

[0044] As explained in Figures 4 to 6, in the bioimaging system 10 according to the second embodiment, the position in which the living organism is placed is guided by accumulating liquid 30 in the container 20. In this way, it is possible to appropriately capture images of the living organism while avoiding contact between the living organism and various devices such as the camera 18.

[0045] <Third Embodiment> The bioimaging system 10 according to the third embodiment will be described with reference to Figure 7. Note that the third embodiment differs from the first and second embodiments described above in some configurations and operations, while other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0046] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the third embodiment will be described with reference to Figure 7. Figure 7 is a side view showing the configuration and operation of the bioimaging system according to the third embodiment. Note that in Figure 7, the same reference numerals are used for elements as in the components shown in Figure 4.

[0047] The bioimaging system 10 according to the third embodiment is configured to discharge the liquid 30 stored in the container 20 after guiding the body to the position where it will be placed. The liquid 30 may be discharged when the guidance is complete (for example, when the finger 50 is placed in the appropriate position). Alternatively, the liquid 30 may be discharged when the image acquisition is complete.

[0048] As shown in Figure 7, the bioimaging system 10 according to the third embodiment is configured to include a discharge drive unit 25 for discharging the liquid 30 stored in the container 20. Specifically, the discharge drive unit 25 is configured to be movable within the container 20, and by moving, it can push out the liquid 30 stored in the container 20. An example of how the discharge drive unit 25 is driven will be described below.

[0049] As shown in Figure 7(a), when liquid 30 is being stored in the container 20, the discharge drive unit 25 is positioned on the edge of the container 20. In this case, the discharge drive unit 25 may be positioned on the edge opposite to the inlet 21 into which the liquid 30 is injected, so as not to obstruct the accumulation of liquid 30 in the container 20.

[0050] As shown in Figure 7(b), when the liquid 30 is discharged from the container 20, the outlet 22 at the bottom of the container 20 opens. The discharge drive unit 25 then moves inside the container 20 towards the outlet 22. Through this operation, the liquid 30 stored in the container 20 is discharged from the outlet 22.

[0051] The above example is merely one example, and the discharge of liquid 30 may be achieved by other configurations.

[0052] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the third embodiment will be described.

[0053] As explained in Figure 7, in the bioimaging system 10 according to the third embodiment, the liquid 30 stored in the container 20 is discharged after guiding the body to the position where it will be placed. This way, the container 20 can be kept clean. Furthermore, even if multiple users use the same container 20, the liquid 30 in the container 20 is replaced each time an image is captured, so guidance can be performed in a clean state.

[0054] <Fourth Embodiment> The bioimaging system 10 according to the fourth embodiment will be described with reference to Figure 8. Note that the fourth embodiment differs from the first embodiment described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0055] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the fourth embodiment will be described with reference to Figure 8. Figure 8 is a side view showing the configuration and operation of the bioimaging system according to the fourth embodiment. Note that in Figure 8, the same reference numerals are used for elements as in the components shown in Figure 4.

[0056] As shown in Figure 8, the bioimaging system 10 according to the fourth embodiment is configured such that the liquid filling unit 110 (see Figure 2) can be filled with mist 40 (i.e., a mist-like liquid) into the imaging range of the camera 18. In addition, the bioguiding unit 120 (see Figure 2) is configured to include a light source 60. The light source 60 guides the position where the biopsy will be placed by irradiating the mist 40 with guide light 70.

[0057] For example, two light sources 60 are provided, and guide light 70 is emitted from each of the two light sources 60 toward the area filled with mist 40. These two guide lights 70 are positioned to intersect at the location where the biological sample is placed. Therefore, when capturing a fingerprint image, the finger 50 should be placed at the point where the guide lights 70 intersect.

[0058] The above-described arrangement of the light sources 60 is merely an example; for example, one light source 60 may be used to guide the position where the living organism is placed. Alternatively, three or more light sources 60 may be used to guide the position where the living organism is placed.

[0059] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the fourth embodiment will be described.

[0060] As explained in Figure 8, in the bioimaging system 10 according to the fourth embodiment, the position in which the living organism is placed is guided by irradiating the mist 40 with guide light 70. In this way, it is possible to appropriately capture images of the living organism while avoiding contact between the living organism and various devices such as the camera 18.

[0061] <Fifth Embodiment> The bioimaging system 10 according to the fifth embodiment will be described with reference to Figure 9. Note that the fifth embodiment differs from the fourth embodiment described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0062] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the fifth embodiment will be described with reference to Figure 9. Figure 9 is a side view showing the configuration and operation of the bioimaging system according to the fifth embodiment. Note that in Figure 9, the same reference numerals are used for elements as in the components shown in Figure 8.

[0063] As shown in Figure 9, the bioimaging system 10 according to the fifth embodiment is configured such that the first light source 61 emits a first guide light 71 and the second light source 62 emits a second guide light 72. The first guide light 71 is visible light of a first wavelength. The second guide light 72 is visible light of a second wavelength that is different from the first wavelength. In other words, the first guide light 71 and the second guide light 72 are guide lights of different colors.

[0064] The first guide light 71 and the second guide light 72 are arranged to intersect at the position where the living organism is placed, similar to the fourth embodiment already described. At the intersection 75 where the first guide light 71 and the second guide light 72 intersect, the color changes due to the difference in wavelengths between the first guide light 71 and the second guide light 72 (i.e., the color becomes different from both the first guide light 71 and the second guide light 72).

[0065] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the fifth embodiment will be described.

[0066] As explained in Figure 9, in the bioimaging system 10 according to the fifth embodiment, the color at the intersection of the first guide light 71 and the second guide light 72, which have different wavelengths, changes. In this way, the user can easily understand the position where the biological organism is placed by the change in color.

[0067] <Sixth Embodiment> The bioimaging system 10 according to the sixth embodiment will be described with reference to Figure 10. Note that the sixth embodiment differs from the fourth and fifth embodiments described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0068] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the sixth embodiment will be described with reference to Figure 10. Figure 10 is a side view showing the configuration and operation of the bioimaging system according to the sixth embodiment. Note that in Figure 10, the same reference numerals are used for elements as in the components shown in Figure 8.

[0069] As shown in Figure 10, the bioimaging system 10 according to the sixth embodiment is configured to include a blower tube 80 in addition to the configuration of the fourth embodiment (see Figure 8). The blower tube 80 is positioned between the camera 18 and the area filled with mist 40. The blower tube 80 may be provided so as to be in contact with the camera 18, for example. The blower tube is configured to blow air so that the mist 40 does not adhere to the camera 18. For example, the blower tube 80 is configured to have a blower inside or outside it.

[0070] Inside the air blower tube 80, air is blown from the bottom to the top (i.e., from the camera 18 side to the mist 40 side). The air blower tube 80 is configured such that its diameter increases towards the top. By making the air blower tube 80 this shape, a vortex is generated inside it. The air coming out of the air blower tube 80 may be configured to flow downwards (i.e., in a direction different from the mist 40) so as not to disperse the mist 40.

[0071] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the sixth embodiment will be described.

[0072] As explained in Figure 10, in the bioimaging system 10 according to the sixth embodiment, air is blown from the camera 18 towards the mist 40. This prevents the mist 40 from adhering to the camera 18. Therefore, it is possible to prevent the camera 18 from being unable to properly capture images of living organisms due to the adhesion of the mist 40.

[0073] <Seventh Embodiment> The bioimaging system 10 according to the seventh embodiment will be described with reference to Figure 11. Note that the seventh embodiment differs from the fourth to sixth embodiments described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0074] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the seventh embodiment will be described with reference to Figure 11. Figure 11 is a side view showing the configuration and operation of the bioimaging system according to the seventh embodiment. In Figure 11, the same reference numerals are used for elements that are the same as those shown in Figure 8. Also, for the sake of clarity, in Figure 11, elements that are less relevant to this embodiment among those shown in Figure 8 have been omitted from the illustration.

[0075] As shown in Figure 11, the bioimaging system 10 according to the seventh embodiment is configured to include a drying blower 90 in addition to the configuration of the fourth embodiment (see Figure 8). The drying blower 90 is configured to blow warm air toward the area filled with mist 40. The drying blower 90 may be the same as the blower provided in the blower tube 70 described in the sixth embodiment, or it may be different.

[0076] The drying fan 90 guides the body to the position where it will be placed, and then blows warm air to dry (or blow away) the mist 40. The drying feeder 90 may blow warm air when the guidance is complete (for example, when the finger 50 is in the appropriate position). Alternatively, the drying fan 90 may blow warm air when image acquisition is complete. The drying fan 90 may be configured to automatically stop blowing warm air after, for example, a predetermined time.

[0077] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the seventh embodiment will be described.

[0078] As explained in Figure 11, in the bioimaging system 10 according to the seventh embodiment, after guiding the position where the living organism will be placed, warm air is blown towards the mist 40. In this way, the mist 40 used to guide the living organism can be removed from the filled area. In addition, the mist 40 that has adhered to the living organism can be removed.

[0079] <Eighth Embodiment> The bioimaging system 10 according to the eighth embodiment will be described with reference to Figure 12. Note that the eighth embodiment differs from the first to seventh embodiments described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0080] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the eighth embodiment will be described with reference to Figure 12. Figure 12 is a side view showing the configuration and operation of the bioimaging system according to the eighth embodiment. In Figure 12, the same reference numerals are used for elements that are similar to those shown in Figures 4 and 8. Also, for the sake of clarity, Figure 12 omits the illustration of elements from Figures 4 and 8 that are less relevant to this embodiment.

[0081] As shown in Figure 12, in the bioimaging system 10 according to the eighth embodiment, the upper member where the finger 50 is placed is configured as a magic mirror 210. This magic mirror 210 is configured to transmit light from below but not transmit light from above. Therefore, it is possible to see what is happening below (for example, the position of the finger 50) from above the magic mirror 210. On the other hand, light from above does not reach the lower side of the magic mirror 210 (i.e., the camera 18 side).

[0082] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the eighth embodiment will be described.

[0083] As explained in Figure 12, in the bioimaging system 10 according to the eighth embodiment, even if a component is located above the position where the body is placed (i.e., closer to the user's eyes), the user can still visually perceive the position of the body. Therefore, it becomes easier to position the body compared to when the position of the body cannot be visually perceived. Furthermore, since light from above is not transmitted, ambient light and other external light do not affect imaging by the camera 18.

[0084] <Ninth Embodiment> The bioimaging system 10 according to the ninth embodiment will be described with reference to Figure 13. Note that the ninth embodiment differs from the first to eighth embodiments described above only in some configurations and operations; other parts may be identical to those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0085] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the ninth embodiment will be described with reference to Figure 13. Figure 13 is a side view showing the configuration and operation of the bioimaging system according to the ninth embodiment. In Figure 13, the same reference numerals are used for elements that are similar to those shown in Figures 4 and 8. Also, for the sake of clarity, in Figure 13, elements that are less relevant to this embodiment among those shown in Figures 4 and 8 have been omitted from the illustration.

[0086] As shown in Figure 13, the bioimaging system 10 according to the ninth embodiment comprises an upper member 221 and a lower member 222. The fingerprint image is captured by guiding the finger 50 between the upper member 221 and the lower member 222. For example, the user inserts the finger 50 through the opening on the right side in the figure, slides it sideways, and stops the finger 50 within the imaging range of the camera 18. After imaging is complete, the user slides the finger 50 again and exits through the exit on the left side in the figure.

[0087] In this embodiment, blowers 230 are provided at the inlet and outlet. The blowers 230 are configured to blow air towards the finger 50. Specifically, the blower 230 on the inlet side blows air towards the finger 50 as it passes through the inlet. The blower 230 on the outlet side blows air towards the finger 50 as it passes through the outlet. The blowers 230 may blow air continuously, or they may be configured to blow air only when they detect the presence of the finger 50.

[0088] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the ninth embodiment will be described.

[0089] As explained in Figure 13, in the bioimaging system 10 according to the ninth embodiment, air is blown onto the body by the blower 230. This makes it possible to blow away any dirt or moisture adhering to the fingers before and after image capture.

[0090] <Tenth Embodiment> The bioimaging system 10 according to the 10th embodiment will be described with reference to Figure 14. Note that the 10th embodiment differs from the first to 9th embodiments described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0091] (Functional configuration) First, the functional configuration of the bioimaging system 10 according to the 10th embodiment will be described with reference to Figure 14. Figure 14 is a block showing the functional configuration of the bioimaging system according to the 10th embodiment. Note that in Figure 14, the same reference numerals are used for elements as in the components shown in Figure 2.

[0092] As shown in Figure 14, the bioimaging system 10 according to the 10th embodiment is configured to include a liquid filling unit 110, a bio-guiding unit 120, an imaging unit 130, a target information acquisition unit 140, and a processing execution unit 150 as components for realizing its function. That is, the bioimaging system 10 according to the 10th embodiment is configured to further include a target information acquisition unit 140 and a processing execution unit 150 in addition to the configuration of the first embodiment (see Figure 2). The target information acquisition unit 140 and the processing execution unit 150 may be processing blocks realized by the processor 11 (see Figure 1) described above.

[0093] The target information acquisition unit 140 is configured to acquire information about the user (hereinafter referred to as "target information" as appropriate) from the user who is taking images of the living body. The target information acquisition unit 140 is configured to acquire target information from, for example, a mobile terminal such as a smartphone, a wearable terminal, or a card. The target information acquisition unit 140 may acquire target information at the time of taking images of the living body. Alternatively, the target information acquisition unit 140 may acquire target information before or after taking images of the living body. The target information may be, for example, information for identifying the user. The target information acquired by the target information acquisition unit 140 is configured to be output to the processing execution unit 150.

[0094] The processing execution unit 150 is configured to perform various processes based on images of living organisms captured by the imaging unit 130. The processing execution unit 150 may be configured to perform, for example, authentication processing using images of living organisms. In addition to authentication processing, the processing execution unit 150 may be configured to perform payment processing using a payment method associated with the authenticated user. In particular, the processing execution unit 150 according to this embodiment utilizes target information acquired by the target information acquisition unit 140 in addition to images of living organisms captured by the imaging unit 130. For example, when the processing execution unit 150 performs authentication processing, the authentication processing may be a two-factor authentication process consisting of authentication processing using images of living organisms and authentication processing using target information.

[0095] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the 10th embodiment will be described.

[0096] As explained in Figure 14, in the bioimaging system 10 according to the tenth embodiment, the target information acquired by the target information acquisition unit 140 is used in the processing executed by the processing execution unit 150. In this way, the processing executed by the processing execution unit 150 can be performed more appropriately compared to when target information is not used. For example, the accuracy of determining the identity of the user can be improved, thereby increasing the security of the process.

[0097] <Embodiment 11> The bioimaging system 10 according to the 11th embodiment will be described with reference to Figures 15 and 16. The 11th embodiment describes a specific configuration example of the 10th embodiment described above, and other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0098] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the 11th embodiment will be described with reference to Figures 15 and 16. Figure 15 is a side view showing the configuration and operation of the bioimaging system according to the 11th embodiment. Figure 16 is a cross-sectional view showing the configuration and operation of the bioimaging system according to the 11th embodiment. In Figures 15 and 16, the same reference numerals are used for elements similar to those shown in Figures 4 and 8. Also, in Figures 15 and 16, for the sake of explanation, elements from Figures 4 and 8 that are less relevant to this embodiment are omitted from the illustration.

[0099] As shown in Figures 15 and 16, the bioimaging system 10 according to the 11th embodiment includes a fingerprint scanning surface 250 that scans the user's finger 50 to capture an image of the fingerprint, and a card scanning surface 260 that acquires target information from a card 300 held by the user. The user can, for example, hold the card 300 with their thumb and index finger and hold it over the card scanning surface 260, while holding their middle finger, ring finger, and little finger over the fingerprint scanning surface 250.

[0100] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the 11th embodiment will be described.

[0101] As explained in Figures 15 and 16, the bio-imaging system 10 according to the 11th embodiment allows for the acquisition of target information simultaneously with the acquisition of images of living organisms.

[0102] <Twelfth Embodiment> The bioimaging system 10 according to the 12th embodiment will be described with reference to Figure 17. Note that the 12th embodiment differs from the first to 11th embodiments described above only in some configurations and operations; other parts may be the same as those of the embodiments described above. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0103] (Configuration and operation) First, the configuration and operation of the bioimaging system 10 according to the 12th embodiment will be described with reference to Figure 17. Figure 17 is a side view showing the configuration and operation of the bioimaging system according to the 12th embodiment. In Figure 17, the same reference numerals are used for elements that are similar to those shown in Figures 4 and 8. Also, for the sake of clarity, Figure 17 omits the illustration of elements from Figures 4 and 8 that are less relevant to this embodiment.

[0104] As shown in Figure 17, the bioimaging system 10 according to the 12th embodiment includes an upper member 271 and a lower member 271, similar to the 9th embodiment described above. The fingerprint image is captured by guiding the finger 50 between the upper member 271 and the lower member 272.

[0105] In this embodiment, wind is blown downwards from the upper member 271, while wind is blown upwards from the lower member 272. The wind from the upper member 271 and the wind from the lower member 272 are of roughly the same strength. Therefore, when a finger 50 is placed between the upper member 271 and the lower member 272, the force of the wind positions the finger 50 approximately midway between the upper member 271 and the lower member 272 (i.e., at the height where the wind hits). In this embodiment, the position where the finger 50 is positioned is suitable for imaging by the camera 18.

[0106] Furthermore, airflow may be continuously supplied from the upper member 271 and the lower member 272, or it may be supplied only when a finger 50 is detected. Also, the airflow from the upper member 271 and the airflow from the lower member 272 do not always have to be of the same strength, and may be supplied at different strengths depending on the situation. For example, if you want to position the finger 50 a little higher, you may weaken the airflow from the top and strengthen the airflow from the bottom. Similarly, if you want to position the finger 50 a little lower, you may strengthen the airflow from the top and weaken the airflow from the bottom.

[0107] (Technical effects) Next, the technical effects obtained by the bioimaging system 10 according to the 12th embodiment will be described.

[0108] As explained in Figure 17, in the bioimaging system 10 according to the 12th embodiment, guidance is provided by air in addition to guidance by the filled liquid. Therefore, compared to the case where only the filled liquid is used for guidance, the position for placing the biological organism can be guided more appropriately. Furthermore, by blowing air, it is also possible to blow away dirt and moisture from the biological organism.

[0109] The processing method of recording a program that operates the configuration of each embodiment in order to realize the functions of each embodiment described above on a recording medium, reading the program recorded on the recording medium as code, and executing it on a computer is also included in the scope of each embodiment. In other words, a computer-readable recording medium is also included in the scope of each embodiment.

[0110] Examples of recording media that can be used include floppy disks, hard disks, optical disks, magneto-optical disks, CD-ROMs, magnetic tapes, non-volatile memory cards, and ROMs. Furthermore, the scope of each embodiment is not limited to programs that perform processing on the recording media alone, but also includes programs that operate on the OS and perform processing in cooperation with other software and the functions of expansion boards. In addition, the program itself may be stored on a server, and part or all of the program may be made downloadable from the server to the user terminal.
