[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. Various features shown in the following embodiments can be combined with each other.

[0009] Incidentally, the program for realizing the software appearing in this embodiment may be provided as a non-transitory computer-readable medium, or may be provided so that it can be downloaded from an external server, or may be provided so that the program is started on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0010] In this embodiment, the term "unit" may also include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In addition, various types of information are handled in this embodiment, and this information may be represented by, for example, physical values ​​of signal values ​​representing voltages and currents, high and low signal values ​​as a binary bit set consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculations may be performed on a circuit in the broad sense.

[0011] In addition, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, a memory, etc. That is, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0012] 1. Hardware Configuration In Section 1, a description will be given of the hardware configuration of the beauty device 1. Fig. 1 is a front view of the beauty device 1. Fig. 2 is a rear view of the beauty device 1.

[0013] 1.1 Overall structure The cosmetic device 1 is composed of an operating unit 11 and a grip unit 12 that supports the operating unit 11. The operating unit 11 is configured to operate by contacting the user's skin, and is provided at one longitudinal end of the grip unit 12. These specific components will be described in more detail below.

[0014] (Operation unit 11) The operating unit 11 has a contact surface 111. A user can stimulate their skin through the contact surface 111 of the beauty device 1. In particular, the contact surface 111 includes a plurality of electrodes 112 arranged such that adjacent electrodes 112 have different polarities, and electrical stimulation such as high frequency is applied to the user's skin through these electrodes 112. Also, whether the contact surface 111 has come into contact with the skin is detected through the electrodes 112.

[0015] 3 and 4 are diagrams showing an example of a contact surface 111 on which linear electrodes 112 are arranged. As shown in FIGS. 3 and 4, the electrodes 112 have linear portions 113 on their outer peripheries. The contact surface 111 also has regions 114 where the opposing electrodes 112 are arranged such that there are multiple locations where the shortest distance between the electrodes is a predetermined length. This will be further explained below using specific examples.

[0016] In the example of contact surface 111a, five electrodes 112 of different widths and lengths are arranged. Here, the electrodes 112a are arranged so that the shortest distance between linear portion 113a of electrode 112a and linear portion 113b of electrode 112b is a predetermined length, thereby forming rectangular region 114a. In other words, linear portion 113 is arranged parallel to linear portions 113 on the periphery of other electrodes 112.

[0017] Here, the straight portion 113 preferably has a length of at least 10 mm or more, and the predetermined length is preferably 1 mm or more and 6 mm or less. Furthermore, in the cosmetic device 1, the length of the portion of the electrodes 112 constituting the region 114 that contacts the region 114 is preferably 10 mm or more. That is, the length of one side of the region 114 constituted by the electrodes 112 having the straight portion 113 is preferably 10 mm or more. Note that the number of electrodes 112 arranged on the contact surface 111 may be 10 or more (contact surface 111b), and the areas of the electrodes 112 may be approximately the same (contact surface 111c and contact surface 111d).

[0018] Furthermore, even if the electrodes 112 are curved, it is preferable that the electrodes 112 are arranged parallel to each other. FIGS. 5 and 6 are diagrams illustrating an example of a contact surface 111 on which curved electrodes 112 are arranged. As illustrated in FIGS. 5 and 6, the electrodes 112 have a linear portion 113 along a portion of their periphery. In the example of contact surface 111e, identically shaped electrodes 112c and 112d are arranged to face each other. Contact surface 111e has linear portions 113 of electrodes 112c and linear portions 113d of electrodes 112d arranged parallel to each other, forming region 114b. As illustrated by contact surfaces 111e, 111f, 111g, 111h, and 111i, it is preferable that the electrodes 112 are arranged so that the distance between the electrodes 112 is constant at every location on the contact surface 111. Furthermore, as in contact surface 111h, there may be a portion other than region 114 where the shortest distance between the electrodes is not a predetermined length.

[0019] 7 and 8 are diagrams showing an example of a contact surface 111 on which electrodes 112 that do not have straight portions 113 are arranged. As shown in FIG. 7, even if the arranged electrodes 112e and 112f do not have straight portions 113, it is preferable that the electrodes are arranged so that there are multiple locations where the shortest distance between the electrodes is a predetermined length. The contact surface 111j shown in FIG. 7 has a curved region 114c, and the width of the region 114c is constant. Note that, as shown in FIG. 8, the contact surface 111 may have an annular electrode 112 arranged thereon (contact surface 111k, contact surface 111l, and contact surface 111m), or may have a spiral shape (contact surface 111o).

[0020] In this way, by arranging the electrodes so that the distance between them is kept constant, it is possible to stimulate the skin evenly over a wide area.

[0021] (Grip part 12) The grip portion 12 is a rod-shaped portion that is grasped by the user. The grip portion 12 may be provided with an operation button (input unit 13) that is operated by the user when starting or ending the operation of the beauty device 1 or when determining the treatment mode.

[0022] 9 is a block diagram showing the hardware configuration of the beauty device 1. The beauty device 1 includes an input unit 13, a storage unit 14, and a control unit 15, and these components are electrically connected via a communication bus 16 inside the beauty device 1. Each component will be further described below.

[0023] (Input section 13) The input unit 13 may be included in the housing of the beauty device 1 or may be externally attached. For example, the input unit 13 is a switch button. The input unit 13 receives an operation input made by a user. The input is transferred as a command signal to the control unit 15 via the communication bus 16, and the control unit 15 can execute predetermined control or calculation as necessary.

[0024] (Storage unit 14) The memory unit 14 stores various information as defined above. This may be implemented, for example, as a storage device such as a solid state drive (SSD) that stores various programs related to the beauty device 1 executed by the control unit 15, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to program calculations. Alternatively, a combination of these may be used. In other words, the hardware resources, such as the storage device and memory, function as the memory unit 14.

[0025] (Control unit 15) The control unit 15 processes and controls the overall operation of the beauty device 1. The control unit 15 is, for example, a central processing unit (CPU) (not shown). The control unit 15 realizes various functions related to the beauty device 1 by reading out predetermined programs stored in the storage unit 14. For example, the CPU, as the control unit 15, accesses information stored in the storage unit 14 and executes various functions (described below) based on the read out information. That is, information processing by software (stored in the storage unit 14) can be specifically realized by hardware (the control unit 15) and executed as each functional unit (see FIG. 5) included in the control unit 15. These will be described in more detail in the next section. Note that the control unit 15 is not limited to a single unit, and multiple control units 15 may be provided for each function. A combination of these may also be used.

[0026] 2. Functional configuration In this section, the functional configuration of the first embodiment will be described. Fig. 10 is a functional block diagram showing the functions of the beauty device 1. As described above, information processing by software (stored in the storage unit 14) is specifically realized by hardware (the control unit 15), and can be executed as each functional unit included in the control unit 15.

[0027] Specifically, the beauty device 1 (control unit 15) includes a detection unit 151, an adjustment unit 152, a determination unit 153, an identification unit 154, and an output unit 155 as functional units.

[0028] The detection unit 151 is configured to be able to execute a detection step. The detection unit 151 detects whether the electrode 112 arranged on the contact surface 111 of the beauty device 1 has come into contact with the skin. The detection unit 151 also detects the current value of the output power and determines the proportion of the entire surface of the electrode 112 that has come into contact with the treatment target.

[0029] The adjustment unit 152 is configured to be able to execute an adjustment step. The adjustment unit 152 adjusts the power to be output to the treatment target. The determination unit 153 is configured to be able to execute a determination step. The determination unit 153 determines an output standard for the power to be output to the treatment target. The output standard determined by the determination unit 153 is stored in the memory unit 14. The identification unit 154 is configured to be able to execute a determination step. When the contact surface 111 has multiple areas 114, the identification unit 154 identifies the amount of current for each area 114. The output unit 155 is configured to be able to execute an output step. In the output step, the output unit 155 outputs power to the treatment target.

[0030] 3. Details of data processing In Section 3, an information processing method executed by the beauty device 1 will be described with reference to an activity diagram. FIG. 11 is an activity diagram showing an example of information processing by the beauty device 1. As shown below, the information processing method includes the following steps. Note that the order of the following processes can be changed as appropriate, and multiple processes may be executed simultaneously, or not all of the processes may be executed.

[0031] When using the beauty device 1, the user applies lotion, emulsion, etc., activates the beauty device 1, and selects a desired treatment mode. Hereinafter, it is assumed that the beauty device 1 has two electrodes 112 arranged on the contact surface 111 (see FIG. 1).

[0032] First, as preparation before the treatment, an output standard is set when the entire surface of the electrode 112 is brought into contact with the skin. First, the user brings the cosmetic device 1 into contact with the skin so that the entire surface of the electrode 112 is in contact with the skin. When the detection unit 151 detects that the entire surface of the electrode 112 has come into contact with the treatment target, the output unit 155 outputs power of a preset voltage (A101).

[0033] The determination unit 153 determines the current value output at this time as the output standard when the entire surface is in contact with the treatment target (A102). This makes it possible to record the skin condition during use of the beauty device 1, even though electrical resistance varies depending on the user's skin type and the cosmetics applied to the skin. The output standard may be set in advance.

[0034] Once the output standard is determined, the user can start treatment using the beauty device 1. When the detection unit 151 detects that the beauty device 1 has come into contact with the user's skin, the output unit 155 outputs power to impart a predetermined beauty effect (A103).

[0035] In A104, the detection unit 151 detects the contact ratio of the electrode 112 to the treatment target relative to the entire surface. Specifically, if the current value output at this time is lower than the reference value determined in A102, the detection unit 151 detects a new ratio of the current value to the output reference in A103 as the contact ratio of the electrode 112 to the treatment target relative to the entire surface. For example, when power of the output reference is applied, the reference current value that actually flows is set to "1." In this case, if the current value actually output in A103 is 0.5, it is determined that 50% of the entire surface area of ​​the electrode 112 arranged on the contact surface 111 is in contact with the treatment target. In this way, the detection unit 151 detects the contact ratio of the electrode 112 to the treatment target relative to the entire surface based on a comparison between the determined output reference and the current value of the output power.

[0036] The adjusting unit 152 adjusts the power so that the amount of current decreases as the contact ratio decreases, and the output unit 155 continues to output the adjusted power for a predetermined time (A105).

[0037] For example, the adjusting unit 152 adjusts the output power in the following manner according to the proportion of the contact area. (1) When the contact rate is 90% or more, 100% of the standard power is output. (2) When the contact ratio is 60% or more but less than 90%, the power output is 85% or more but less than 95% of the standard output, preferably 90% of the standard output. (3) When the contact ratio is 40% or more but less than 60%, the power output is 75% or more but less than 85% of the standard output, preferably 80% of the standard output. (4) When the contact ratio is 20% or more but less than 40%, the power output is 55% or more but less than 75% of the standard output, preferably 60% of the standard output. (5) When the contact ratio is 19% or less, the power output is 35% or more but less than 55% of the standard output, preferably 40% of the standard output.

[0038] It is preferable to return to A103 and repeat the series of processes after a predetermined time has elapsed. Furthermore, when the user completely removes the electrode 112 from the skin to treat another area, causing the flowing current to become zero, and then the contact surface 111 touches the skin again to resume treatment, it also returns to A103. Furthermore, it is preferable to return to A101 when the treatment mode is switched, and when the user stops activation of the beauty device 1, this information processing ends.

[0039] In this way, the area of ​​the skin in contact with electrode 112 is detected, and the power output is adjusted according to the contact ratio (contact area) with the skin. As a result, when treating an area with many bumps, such as the nose or chin, if the area in contact with contact surface 111 is small, the current will flow concentratedly at the contact point, but the amount of current can be reduced, making it possible to prevent a sudden rise in temperature.

[0040] 4. Variations In Section 4, processing when three or more electrodes 112 are arranged on the contact surface 111, thereby forming a plurality of regions 114, will be described.

[0041] 4.1 Variation 1 When there are multiple regions 114, power is output between each electrode, and the current value that actually flows through the skin is set to the reference current value "1." Then, A104 detects the contact ratio of each region 114 to the entire surface based on a comparison between the actually flowing current value and the reference current value, and then detects the contact ratio of each region 114. That is, the detection unit 151 detects the contact ratio of the treatment target to the entire surface of each region 114 based on a comparison between the output standard set for each region 114 and the current value of the power output for each region 114. Then, the power output is adjusted according to the contact ratio.

[0042] The determination unit 153 periodically outputs power to different regions 114, thereby determining an output standard for each region 114 (A102). For example, as shown in FIG. 3, in the case where there are four regions 114 (region 114a, region 114b, region 114c, and region 114d), the output unit 155 periodically outputs power to each region 114 while all of the regions 114 are in contact with the treatment target. For example, the determination unit 153 applies a predetermined amount of power to the skin, and determines the current value output per 0.01 second after the start of output as the reference current value actually flowing through the skin, thereby determining the output standard for each region 114. In other words, this reference current value becomes the output standard for each region 114.

[0043] In A103, when the electrode 112 touches the skin again, power is periodically output to each region 114, just as when the output standard was determined, and the identification unit 154 identifies the amount of current for each region 114 based on the current value for each time period. For example, if the standard current value (output standard) for each region 114 is set to "1", the output unit 155 outputs a current value of "1" to each region 114 for 0.01 seconds.

[0044] In this case, output is made for 0.01 seconds for each of the four regions 114. For example, assuming that the regions 114a, 114b, 114c, and 114e are output in this order, one cycle will complete in 0.04 seconds, as shown below. (1) The output target from the start of output to 0.01 seconds is area 114a. (2) The output target from 0.01 seconds to 0.02 seconds is the area 114b. (3) The output target from 0.02 seconds to 0.03 seconds is the area 114c. (4) The output target from 0.03 seconds to 0.04 seconds is the area 114e.

[0045] In A103, if the current value output from the start of output until 0.01 seconds has elapsed is "1" and the current value output from 0.01 seconds after the start of output until 0.02 seconds is "0.5", it is determined that the entire surface of area 114b that was the output target between 0.01 seconds and 0.02 seconds is not in contact with the treatment target.

[0046] In response to this, the detection unit 151 determines that the contact ratio for the entire surface of this region 114 is 50% because the current value output from 0.01 seconds to 0.02 seconds is 50% of the reference current value "1," which is the output reference. Thereafter, the adjustment unit 152 adjusts the power so that the amount of current output from 0.05 seconds to 0.06 seconds, when the cycle has completed one cycle and a new cycle has started, is 80% of the output reference (A104). Similarly, in the third cycle, the amount of current output from 0.09 seconds to 0.1 seconds is also adjusted. In this way, the detection unit 151 detects the contact ratio for each region 114 based on a comparison between the output reference for each region 114 and the current value for the identified region 114, and the adjustment unit 152 adjusts the power to an output according to the contact ratio for each region 114 (A105). Furthermore, by repeating the output periodically in this manner, even if it is not possible to individually recognize the area 114 to be output for each time unit in the cycle, it is possible to detect the contact ratio for each area 114. Note that when the processing in A105 has been executed for a predetermined time, the processing may be returned to A103 and repeated, or when the above cycle has been repeated a predetermined number of times, the processing may be returned to A103.

[0047] 4.2 Variation 2 When the areas 114 to be output targets can be individually identified in advance, the determination unit 153 determines an output standard for each area 114 by outputting power for each area 114, and the detection unit 151 can detect the contact ratio for each area 114. In this case, the detection unit 151 can detect the contact ratio for each area 114 even when power is not output periodically.

[0048] 4.3 Variation 3 In the above example, the electrode 112 functions to detect contact with the skin and apply electrical stimulation. However, the cosmetic device 1 may have light-receiving elements disposed at equal intervals between the electrodes on the contact surface 111, and detect contact via the light-receiving elements. The light-receiving elements may be disposed at equal intervals of 1 mm or more and 4 mm or less on the contact surface 111 on which the linear electrodes 112 (see FIGS. 3 and 4) are disposed. Specifically, the light-receiving elements may be 1, 2, 3, or 4 mm, or may be within a range between any two of the values ​​exemplified here. In this case, the detection unit 151 determines that the entire surface of the electrode 112 is not in contact if the amount of light received by the light-receiving element is higher than a threshold. For example, suppose three light-receiving elements are disposed between the electrodes. In this case, if the amount of light received by two of the three light-receiving elements is higher than a threshold, the detection unit 151 determines that the light-receiving element is not in contact, and determines that the area in which the electrode 112 is in contact is one-third. In this way, in A104, the detection unit 151 detects the proportion of the contact area based on the proportion of the number of light receiving elements determined to be out of contact with the total number of light receiving elements arranged on the surface of the contact surface 111.

[0049] Furthermore, light-emitting elements may be arranged at a predetermined interval together with the light-receiving elements. In this case, if the amount of light emitted by the light-receiving element from the light-emitting element is lower than a threshold, the detection unit 151 determines that the amount of reflection from the light-emitting element is small and that the light-receiving element is not in contact with the skin. In this way, the detection unit 151 may determine whether or not the electrode 112 is in contact by measuring the reflection from the light-emitting element.

[0050] To summarize the above, as explained in Section 1, by arranging the electrodes 112 so that they can stimulate the skin evenly over a wide area, it is possible to quickly apply electrical stimulation over a wide area. However, if some of the electrodes 112 are not in contact, there is a risk that the electricity will flow concentratedly in the contact area, causing excessive heat. However, with the beauty device 1 having the above configuration, the output can be adjusted according to the contact ratio with the skin, making it safer and more reliable for general users to use.

[0051] 5.Other The cosmetic device 1 according to this embodiment may be configured as follows.
