  Embodiments of the present invention will be described below with reference to the drawings.

  Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is an external view of a mobile communication terminal 1 according to a first embodiment of the present invention. The mobile communication terminal 1 is configured by connecting a first housing 11 and a second housing 12 so as to be openable and closable. FIG. 1 shows a state in which the first housing 11 and the second housing 12 are opened from the user side. However, the casing configuration of the mobile communication terminal 1 is not limited to the so-called folding type as shown in FIG.

  A display unit 14 made of, for example, a liquid crystal device is attached to the first housing 11. The display unit 14 can display characters and images, and the mobile communication terminal 1 uses the display unit 14 to execute applications involving screen display (for example, e-mail transmission / reception, web page browsing, phone book creation and browsing, etc.) can do. A receiver 15 is attached to the first housing 11. A transmitter 16 is attached to the second housing 12. The mobile communication terminal 1 can be used for voice calls by including the receiver 15 and transmitter 16.

  The second housing 12 is provided with an operation input unit 17 (represented by being surrounded by a broken line frame) composed of a plurality of operation keys. The operation input unit 17 may include operation keys provided on the side surface or the back surface of the first housing 11 or the second housing 12 (not shown). By operating the operation keys belonging to the operation input unit 17, it becomes possible to input text and operation commands to the mobile communication terminal 1. All of the display unit 14, the receiver unit 15, the transmitter unit 16, and the operation input unit 17 described above function as a human interface unit of the mobile communication terminal 1.

  A skin measurement sensor 18 is attached below the display unit 14 of the first housing 11. The skin measurement sensor 18 can measure the moisture and oil content of the skin in contact with the electrical, optical, and other methods described in the background art. The skin measurement sensor 18 is attached to the first housing 11 in the same manner as the reception unit 15 or the display unit 14.

  FIG. 2 is a block diagram of the mobile communication terminal 1. The mobile communication terminal 1 includes an antenna 19 and a transmission / reception unit 20 and can transmit and receive radio waves with a mobile communication base station (not shown). The mobile communication terminal 1 includes a voice interface unit 21, a control unit 22, and a memory 23.

  The transmission / reception unit 20, the audio interface unit 21, the memory 23, and the display unit 14, the operation input unit 17, and the skin measurement sensor 18 described with reference to FIG. 1 are connected to the control unit 22 through, for example, a common bus. Monitored and controlled by. The control unit 22 is configured by a single processing device such as a microprocessor or a combination thereof.

  In the case of a voice call, an encoded voice signal transmitted from the other party through the base station is received by the transmitting / receiving unit 20 via the antenna 19 and subjected to processing such as demodulation and error correction, and further, a voice interface unit. Decoded at 21 and reproduced from the receiver 15. The voice picked up by the transmitter 16 is encoded by the voice interface unit 21, error-correction encoded, modulated and amplified by the transmitter / receiver 20, and then transmitted from the antenna 19 to the base station.

  FIG. 3 is a diagram illustrating a usage mode of the mobile communication terminal 1 in a voice call. In a normal voice call, the first casing 11 and the second casing 12 are opened to each other, the second casing 12 is held by hand, and the second casing is used with the earpiece on the earpiece 15 above the first casing 11. It is used in a state where the lower transmitter 16 is brought close to the mouth. Then, the skin measurement sensor 18 attached below the display unit 14 of the first housing 11 is in a position where it can come into contact with the skin (for example, near the cheek) of the caller during a voice call (in the block arrow in the figure). To express.).

  When one of the operation keys belonging to the operation input unit 17 is operated in the state illustrated in FIG. 3, the skin measurement sensor 18 is activated and skin measurement can be started. Further, it is set in advance so that skin measurement is started with the start of a voice call, and the skin measurement sensor 18 is activated in response to an operation for starting transmission or reception so that skin measurement is started. You can also

  When the skin measurement ends after the skin measurement is performed for a predetermined time, the skin measurement sensor 18 notifies the control unit 22 of the end of the measurement. In response to the notification, the control unit 22 causes the reception unit 15 (or a speaker (not shown) provided separately from the reception unit 15) to output a measurement end notification sound via the voice interface unit 21. it can. Upon receiving the notification, the control unit 22 can also notify the end of measurement by displaying characters on the display unit 14.

  Skin measurement sensor 18 sends the acquired data to control unit 22 after the measurement is completed. The control unit 22 can process the acquired data and display the result of the skin measurement on the display unit 14. Prior to the start of skin measurement, measurement conditions (for example, age) can be set in advance, and the control unit 22 can process acquired data based on the measurement conditions.

  The control unit 22 can store the acquired data of the skin measurement sensor 18 or the data of the processing result in the memory 23. The control unit 22 can read out the stored data from the memory 23 and display it on the display unit 14 as a skin measurement history.

  Prior to the start of skin measurement, the person to be measured may be authenticated. For example, when an operation for starting skin measurement using an operation key belonging to the operation input unit 17 or setting the start of skin measurement at the same time as the start of a voice call is performed, the control unit 22 displays a password input prompt on the display unit 14. I do. The authentication means is not limited to a password. For example, the mobile communication terminal 1 may be performed using a biometric authentication method by providing a biometric (fingerprint, vein, iris, etc.) authentication sensor (not shown).

  When authentication information (password or the like) matches that registered in advance, the start of skin measurement can be permitted. It is also possible to register a plurality of authentication information corresponding to a plurality of persons to be measured, and to store the acquired data or the processing result data and display the history for each authentication information. The above-described measurement conditions (such as age) may be set in combination with registration of authentication information.

  The skin measurement process described above will be described again with reference to the flowchart of FIG. It is assumed that measurement conditions (age and the like) have been set in advance, and authentication information (for example, password) has been registered in advance and stored in the memory 23, respectively.

  When the process is started (“START”), an operation for setting in advance is performed using the operation input unit 17 so that skin measurement is started when a voice call is started (step S1). Such an operation can be selectively performed from a menu displayed on the display unit 14 in a so-called standby state of the mobile communication terminal 1, for example. Note that the operation in step S1 is not limited to the operation for starting the skin measurement accompanying the start of the voice call. For example, the operation may be accompanied by the start of dial input for making a call, or in addition to the telephone directory. It may be based on an operation for opening. Further, skin measurement may be started based on receiving an incoming call.

  Then, the control unit 22 displays a message for requesting input of a password for authenticating the person to be measured on the display unit 14 (step S2), and waits for the password to be input using the operation input unit 17 (step S2). “NO” in S3). When the password is input (“YES” in step S3), the control unit 22 determines whether the input password matches the registered password stored in the memory 23.

  If the result of the determination does not match (“NO” in step S4), the control unit 22 displays a message warning the mismatch of the password on the display unit 14 (step S5), and returns to step S2. If the results of the above determination match (“YES” in step S4), the control unit 22 waits for an operation to start transmitting or receiving a voice call using the operation input unit 17 (in step S6). “NO”).

  When an operation for starting transmission or reception is performed (“YES” in step S6), the control unit 22 activates the skin measurement sensor 18 and starts skin measurement (step S7). Thereafter, the control unit 22 waits for a measurement end notification from the skin measurement sensor 18 ("NO" in step S8). When the measurement end notification is received from the skin measurement sensor 18 (“YES” in step S8), the control unit 22 notifies the measurement end from the receiver unit 15 or the speaker (not shown in FIGS. 1 and 2) via the voice interface unit 21. A sound is emitted (step S9).

  The skin measurement sensor 18 transfers data such as skin moisture and oil content acquired by the measurement to the control unit 22 (step S10). The control unit 22 processes the acquisition data based on the measurement conditions (for example, age) that are set in advance and stored in the memory 23, and stores the acquisition data or the processing result data in the memory 23. The control unit 22 displays the result of skin measurement on the display unit 14 based on the processing result data automatically or in response to an operation using the operation input unit 17 (step S11), and ends the processing (“END”). ).

  When skin measurement is not started with the start of a voice call but skin measurement is started by any of the operation keys belonging to the operation input unit 17, step S1 is omitted and the operation is performed in step S6. What is necessary is just to change so that the presence or absence of operation of a key may be determined.

  If authentication of the measurement subject is unnecessary, steps S2 to S5 may be omitted. Further, in the case where the measurement subject is authenticated by another method such as biometric authentication, steps S2 to S5 may be modified to be compatible with the authentication method. In addition, the flowchart of FIG. 4 can be variously modified according to the skin measurement condition setting and mode.

  With reference to FIG. 5, an example of the display mode of the result of skin measurement will be described. FIG. 5 is a diagram illustrating a screen for displaying the result of skin measurement on the display unit 14. Following the text display of “skin measurement result” at the top of the screen, the name and age based on the registered authentication information and measurement conditions are displayed.

  Moisture is displayed in a bar chart, and numerical values from “−5” to “+5” are graduated. In this display, the scale “0” corresponds to the standard value for the age of the person being measured, the scale “−5” corresponds to the lower limit of the moisture deficit state at the age of the person being measured, and the scale “+5”. "" Corresponds to the upper limit of the excess water state at the age of the person being measured. The oil content is also displayed in a similar bar chart.

  The balance is temporarily assumed as an index representing the overall skin care degree obtained from the measurement results of age and moisture and oil content. The balance is displayed by the star mark color classification in 10 stages, and the best balance is expressed when the number of black star marks is 10. In the example of FIG. 5, the number of black star marks is seven, which indicates that the number is 4th when the skin balance is good. For example, the number of star marks is determined based on the moisture measurement result and the oil measurement result.

  With reference to FIG. 6, an example of the display mode of the history of skin measurement will be described. FIG. 6 is a diagram illustrating a screen that displays a history of skin measurement results on the display unit 14. Following the text display of “skin measurement history” at the top of the screen, the name and age based on the registered authentication information and measurement conditions are displayed.

  In FIG. 6, the history of each numerical value of moisture, oil content, and balance displayed on the skin measurement result screen of FIG. 5 is displayed in the form of a line graph. The horizontal axis of the graph corresponds to the measurement date, and the upper row represents the month and the lower row represents the day among the upper and lower numbers representing the date. Therefore, the line graph of FIG. 6 represents the history of the results of skin measurements performed on June 20, June 27, July 4, and July 11, respectively.

  The vertical axis on the left side of the graph corresponds to the numerical values calibrated on the moisture and oil bar chart described with reference to FIG. The vertical axis on the right side of the graph corresponds to the number of balanced black star marks described with reference to FIG. In the history data, moisture is represented by a solid line, oil is represented by a broken line, and balance is represented by a one-dot chain line.

  Since the skin measurement result and the history display as described above can intuitively grasp the degree of skin care and its temporal transition, it is useful for management and improvement of the degree of skin care. Note that the skin measurement results and history display forms, numerical values, and representations shown in FIGS. 5 and 6 are examples, and various modifications are possible, and the present invention is not limited in any way.
