Description

  The present invention relates to a method and apparatus for recording / reproducing biological information such as a person's pulse (pulse) and respiration.

  It is considered that biological information such as a person's pulse and breathing is used not as a medical or medical purpose, but as an indication of the state of a person's emotion, as information that conforms to content such as images and music. Yes.

  For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2004-219914), in order to reproduce an atmosphere such as a concert venue or a live venue, information on music and video information is multiplexed with information on the performers and performers. It is shown that a sensory stimulus is given to a viewer by biometric information on the receiving side.

  Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2007-280485), the user's biometric information at the time of content playback is measured and recorded on a recording medium as an indication of a change in the user's emotion, and played back from the recording medium. It is shown that the content is reproduced by changing the reproduction mode according to the biometric information.

The prior art documents listed above are as follows.
JP 2004-219914 A JP 2007-280485 A

  For example, when the biological information is a pulse, the measurement signal (measurement value data) of the human biological information continuously changes in waveform (measurement value) as shown by the measurement signal S1 (measurement value data D1) in FIG. To be.

  However, it is difficult to change the amplitude of the vibration by following the change of the waveform of the measurement signal even if such a measurement signal is directly used as a drive signal, for example, driving a vibration motor and giving vibration to the user, It is difficult for a user to sense biometric information of a target person (which may be the user himself), that is, a pulse as content.

  Moreover, in the first place, in the case of a pulse, the peak value (maximum value or minimum value) of the measurement signal hardly changes regardless of changes in the state of the subject's emotion or the like, and when the subject is excited, the pulse Becomes higher (higher pulse rate), the time interval between adjacent peaks of the measurement signal is longer, and when the subject is calm, the pulse is lower (lower pulse rate) and the adjacent peak of the measurement signal A change in the state of the subject's emotion or the like appears as a change in the pulse rate, that is, a change in the time interval between adjacent peaks of the measurement signal.

  Therefore, in the method in which the biological information measurement signal is directly used as the drive signal as described above, the user cannot sense the change in the pulse rate, that is, the change in the state of the subject's emotion or the like as the content.

  The same applies to the case where an LED (light emitting diode) is turned on using the measurement signal as a drive signal, and the same applies to the case where the biological information is respiration.

  Furthermore, when recording biological information on a recording medium, if the measurement signal (measurement value data) is recorded as it is, the amount of data to be recorded becomes unnecessarily large.

  Therefore, the present invention can easily and accurately express the subject's biological information as an indication of the state of the subject's emotions, etc., and can record and reproduce it so that it can be sensed as content, while recording with a small amount of data. It is something that can be done.

The recording / reproducing method of the present invention comprises:
Measuring the subject's biological information and obtaining measured value data;
Detecting the feature quantity of the biological information from the measurement value data and obtaining the feature quantity data;
Recording the feature data on a recording medium;
Reproducing the feature amount data from the recording medium;
Generating a drive signal from the reproduced feature data;
Driving the playback device with the drive signal;
It is characterized by providing.

  In the above recording / reproducing method, not the measurement value data (measurement signal) itself of the biological information but, for example, when the biological information to be measured is a pulse, the time between adjacent peaks of the measurement value is used as a feature amount of the biological information. The interval is detected and recorded as feature value data on a recording medium. At the time of reproduction, a pulse signal of the above time interval is generated as a drive signal from the reproduced feature value data, and a reproduction device such as a vibration motor or LED Is driven.

  Therefore, the user can perceive the biometric information of the subject as content indicating a state such as the subject's emotion. In addition, since the feature amount data has a smaller data amount than the measurement value data, the biometric information can be recorded with a smaller data amount.

  As described above, according to the present invention, the biological information of the subject can be simply and accurately expressed as indicating the state of the subject's emotions, and can be recorded and reproduced so that it can be sensed as content. It is possible to record with a small amount of data.

[1. First Embodiment (Recording / Reproduction of Biological Information): FIGS. 1 to 3]
(1-1. Device configuration: Fig. 1)
FIG. 1 is a diagram illustrating an example of a recording / reproducing apparatus according to the first embodiment.

  The recording / reproducing apparatus 10 of this example includes a biosensor 11, an A / D converter 12, a feature amount detecting unit 13, a recording / reproducing unit 14, a recording medium 15, a drive signal generating unit 16, a vibration motor 17, a red LED 18, a blue LED 19, The control unit 21 and the operation unit 22 are provided.

  The biological sensor 11 is a pulse sensor, a respiratory sensor, or the like that measures biological information such as a pulse or respiration of the subject (person to be measured) 1.

  The A / D converter 12 performs A / D conversion on the measurement signal S1 output from the biosensor 11, and outputs measurement value data D1.

The feature amount detection unit 13 detects (extracts) a feature amount as will be described later of the biological information of the subject 1 from the measurement value data D1,
The feature data D2 is output.

  The recording medium 15 is an internal recording medium such as a hard disk or a semiconductor memory built in the recording / reproducing apparatus 10 or a removable recording medium such as an optical disk or a semiconductor memory mounted in the recording / reproducing apparatus 10.

  The recording / reproducing unit 14 records the feature amount data D2 output from the feature amount detecting unit 13 on the recording medium 15 during recording, and reproduces the feature amount data D2 recorded thereon from the recording medium 15 during reproduction. Therefore, it is configured by hardware and software (program) corresponding to the recording medium 15.

  The drive signal generation unit 16 generates a drive signal corresponding to the feature amount as described later from the feature amount data D2 sent from the recording / reproduction unit 14 during reproduction.

  The vibration motor 17, the red LED 18, and the blue LED 19 are examples of a reproduction device (output device).

  That is, in this example, the vibration motor 17, the red LED 18, and the blue LED 19 are used as playback devices. The vibration motor 17 is driven by the drive signal S2, the red LED 18 is driven by the drive signal S3, and the blue LED 19 is driven by the drive signal S4. This is the case.

  However, as described later, only one or two of the vibration motor 17, the red LED 18, and the blue LED 19 are used depending on whether the biological information to be measured is a pulse or a respiration, or another A playback device can be used.

  When the recording / reproducing apparatus 10 is configured in a mobile phone terminal, as the vibration motor 17, a vibration motor that is generally provided for a manner mode or the like in the mobile phone terminal can be used.

  The control unit 21 controls each unit of the recording / reproducing apparatus 10 and is omitted in the drawing, but the CPU, a ROM in which various programs executed by the CPU and necessary fixed data are written, and programs and data are expanded. It is comprised by RAM etc.

  The operation unit 22 is used by the user to instruct the control unit 21 to measure and record biometric information.

  The user is a person who uses the recording / reproducing apparatus 10. The target person 1 may be the user himself or another person.

(1-2. When the biological information is a pulse: FIG. 2)
When the biological information to be measured is a pulse, the biological sensor 11 in FIG. 1 is a pulse sensor.

  A simple way to measure the pulse is to apply infrared light to the subject's skin and measure the intensity (light intensity) of the reflected light from the red blood cells in the blood, or if the skin is thin, such as the earlobe, A method of measuring strength (light quantity) can be used.

  In this case, as shown in FIG. 2, as the measurement signal S1, the peak value (maximum value or minimum value) and amplitude hardly change, and the time interval between adjacent peaks is such as the feeling of the subject 1 or the like. It changes according to the state. The measurement value data D1 is the same because the measurement signal S1 is only A / D converted.

  Therefore, in this case, the feature amount detection unit 13 detects a time interval between adjacent peaks of the measurement value data D1 (measurement signal S1) as a feature amount of biological information (pulse).

  Specifically, as shown in FIG. 2, first, the time interval T1 between the peak point P1 and the next peak point P2 is detected, and data indicating the time interval T1 is generated as the feature amount data D2, and then The time interval T2 between the peak point P2 and the next peak point P3 is detected, data indicating the time interval T2 is generated as the feature amount data D2, and the time intervals between adjacent peaks are sequentially detected. Then, data indicating the time interval between adjacent peaks is sequentially generated.

  In this case, the feature amount data D2 has a data amount significantly smaller than that of the measurement value data D1, and is obtained by compressing the measurement value data D1 by a compression method used for compression of an image signal, an audio signal, and the like. The amount of data is small even when compared.

  At the time of recording, the feature amount data D2 is recorded on the recording medium 15.

  At the time of reproduction, the drive signal generation unit 16 uses the same feature value data D2 reproduced from the recording medium 15 as shown in FIG. 2 as the drive signal S2, and each peak point P1, P2, P3, P4 at the time of measurement recording. A pulse signal having a constant pulse width is generated at each timing corresponding to the timing of.

  When the biological information to be measured is a pulse, the vibration motor 17 is driven by the drive signal S2 during reproduction, for example, as shown in FIG.

  Therefore, the recording / reproducing apparatus 10 oscillates intermittently at the above time intervals T1, T2, T3, T4,..., And the user can see the state of the pulse of the subject 1 during measurement recording, The interval (pulse rate) can be sensed.

  The red LED 18 or the blue LED 19 may be driven by the drive signal S2. In this case, the red LED 18 or the blue LED 19 blinks at the time intervals T1, T2, T3, T4..., And the user can similarly sense the state of the pulse of the subject 1 at the time of measurement recording. .

  A plurality of vibration motors 17, red LEDs 18 and blue LEDs 19 may be driven by the drive signal S2.

(1-3. When biological information is respiration: FIG. 3)
When the biological information to be measured is respiration, the biosensor 11 in FIG. 1 is a respiration sensor.

  In this case, as shown in FIG. 3, the measurement signal S <b> 1 is a direction in which the signal increases in a period in which the subject 1 is breathing, and a direction in which the signal decreases in a period in which the subject 1 is exhaling. It is. The measurement value data D1 is the same because the measurement signal S1 is only A / D converted.

  Therefore, in this case, the feature amount detection unit 13 causes a phenomenon in which the measurement value data D1 (measurement signal S1) is increasing as the feature amount of the biological information (respiration) as time lengths T11, T21,. .. Are detected alternately as feature quantity data D2, and whether the time length is a period of breathing or a period of breathing. Are sequentially generated.

  The feature amount data D2 in this case also has a data amount that is significantly smaller than the measurement value data D1, and is obtained by compressing the measurement value data D1 with a compression method used for compression of image signals, audio signals, and the like. The amount of data is small even when compared.

  At the time of recording, the feature amount data D2 is recorded on the recording medium 15.

  At the time of reproduction, the drive signal generation unit 16 uses the same feature value data D2 reproduced from the recording medium 15 as the drive signal S3 as shown in FIG. A binary signal (rectangular wave signal) that is at a high level during the period corresponding to, and is at a low level during the period corresponding to the period during which the subject 1 was exhaling at the time of measurement recording, and as the drive signal S4, The signal is inverted with respect to the drive signal S3, that is, in the period corresponding to the period in which the subject 1 was inhaling at the time of measurement recording, and becomes low in the period in which the subject 1 at the time of measurement recording was exhaling. A binary signal that is high in the corresponding period is generated.

  When the biological information to be measured is breathing, during reproduction, for example, as shown in FIG. 1, the red LED 18 is driven by the drive signal S3, and the blue LED 19 is driven by the drive signal S4.

  Therefore, in the period corresponding to the period in which the subject 1 was breathing at the time of measurement recording, the red LED 18 was lit, the blue LED 19 was not lit, and the period during which the subject 1 was breathing at the time of measurement recording In the period corresponding to, the blue LED 19 is lit and the red LED 18 is not lit.

  Therefore, the user can perceive the state of breathing of the subject 1 at the time of measurement recording, that is, the time during which he / she breathed and the time during which he / she exhaled and its change.

  On the contrary, the blue LED 19 may be driven by the drive signal S3 and the red LED 18 may be driven by the drive signal S4.

  Further, for example, the vibration motor 17 and the red LED 18 may be driven by the drive signal S3, and the blue LED 19 may be driven by the drive signal S4.

  Further, for example, only one of the red LED 18 and the blue LED 19 or only the vibration motor 17 may be driven by the drive signal S3.

  Furthermore, although not shown, a device that expands and contracts in accordance with a drive signal may be used as a playback device, and the playback device may be driven by the drive signal S3. In this case, the playback device expands during the period corresponding to the period during which the subject 1 was breathing during the measurement recording, and during the period corresponding to the period during which the subject 1 was breathing during the measurement recording. Since the device is compressed, it is possible to more intuitively detect the state of breathing of the subject 1 during measurement recording.

(1-4. When recording and playback are performed by different devices)
In the example of FIG. 1, when the recording medium 15 is a removable recording medium, the recording medium 15 in which the biological information is recorded as the feature amount data D2 as described above by the recording / reproducing apparatus 10 is removed from the recording / reproducing apparatus 10. It is also possible to attach to another recording / reproducing apparatus or reproducing apparatus that can reproduce biological information as described above and reproduce the biological information as described above using another recording / reproducing apparatus or reproducing apparatus.

  Furthermore, in this case, when the user assigns or lends the recording medium 15 to another user, the biological information can be reproduced as described above by the other user's recording / reproducing apparatus or reproducing apparatus.

(1-5. Relationship with recording / playback of content such as images and music)
The above-described recording / reproduction of biometric information can be performed regardless of the recording / reproduction of content such as images and music. However, if it is performed in association with the recording / reproduction of content such as images and music as described below, the content Can add a sense of realism to the reproduction of

  A first example of recording and reproducing biometric information in association with content recording and reproduction is a case where biometric information is recorded during reproduction of recorded content.

  For example, in the example of FIG. 1, when content such as an image or music is recorded on the recording medium 15, when the content is played back, the user himself / herself becomes the target person 1 and the recording / playback apparatus 10 The pulse and respiration are measured, and the feature data D2 is multiplexed with the content data and recorded on the recording medium 15.

  According to this, when the content is reproduced from the next time onward, it is possible to reproduce the user's own pulse and breath when the user has previously viewed the content in synchronization with the reproduction of the content. Adds a sense of realism to the reproduction of

  A second example of recording / reproducing biometric information in association with content recording / reproduction is a case where biometric information is recorded when unrecorded content is recorded. An example of this case will be described below as a second embodiment.

[2. Second Embodiment: FIGS. 4 to 7]
As an example of recording and reproducing content simultaneously with biometric information, a case where a still image or a moving image is shot and recorded and reproduced with a digital still camera, a digital video camera, or a mobile phone terminal with a camera is used as the second embodiment. Show.

(2-1. First example: FIG. 4)
FIG. 4 shows a first example of the imaging recording / reproducing apparatus of the second embodiment.

  The imaging recording / reproducing apparatus 30 in this example is different from the recording / reproducing apparatus 10 in the example of FIG. 1 in that an imaging unit 31, an image processing unit 33, a microphone 35, an audio amplifier circuit 37, an audio processing unit 39, and a demultiplexing unit 51. A delay correction unit 55, an image processing unit 41, an image display unit 43, an audio processing unit 45, an audio amplifying circuit 47, and a speaker 49 are added.

  The reproduction device 25 for biological information is the vibration motor, the LED, or the expansion device described above.

  The image display unit 43 is a liquid crystal display, an organic EL display, or the like.

  The target person 1 in this case is a person who takes a still image or a moving image by the imaging recording / reproducing apparatus 30. The biological sensor 11 is, for example, a pulse sensor or a respiration sensor.

  In the imaging recording / reproducing apparatus 30 of this example, at the time of recording, the subject is photographed as a still image or a moving image by the imaging unit 31, sound such as music is acquired by the microphone 35, and the subject at the time of photographing is captured by the biosensor 11. One pulse or breath is measured.

  Still image or moving image data from the imaging unit 31 is processed by the image processing unit 33, further compressed, and sent to the demultiplexing / separating unit 51.

  The audio signal from the microphone 35 is amplified by the audio amplification circuit 37, converted into digital audio data by the audio processing unit 39, further compressed, and sent to the demultiplexing / separating unit 51.

  The compressed image data from the image processing unit 33 and the compressed audio data from the sound processing unit 39 are synchronized with each other by a compression method related to images and sounds.

  On the other hand, the measurement signal from the biosensor 11 is A / D converted by the A / D converter 12, and measurement value data is obtained from the A / D converter 12. Further, the feature amount detection unit 13 detects the feature amount of the subject 1 from the pulse or breath from the measured value data, and obtains feature amount data.

  The feature amount data from the feature amount detection unit 13 is delay-corrected by the delay correction unit 55 so as to be synchronized with the compressed image data and the compressed audio data, and is sent to the demultiplexing / separating unit 51. .

  At the time of shooting and recording, the demultiplexing unit 51 multiplexes the compressed image data, the compressed audio data, and the delay-corrected feature data, and records them on the recording medium 15 by the recording / reproducing unit 14.

  At the time of reproduction, the multiplexed reproduction image data, compression audio data, and feature amount data are reproduced from the recording medium 15 by the recording / reproduction unit 14, and the demultiplexing unit 51 compresses the compressed image data, compression audio data, and feature amount data. Are separated.

  The separated compressed image data is expanded by the image processing unit 41, further converted into an image signal for display, sent to the image display unit 43, and a still image or a moving image is displayed on the image display unit 43.

  The separated compressed audio data is expanded by the audio processing unit 45, further converted into an analog audio signal, amplified by the audio amplifying circuit 47, sent to the speaker 49, and the audio is output from the speaker 49.

  Further, the separated feature amount data is delay-corrected by the delay correction unit 55 so as to be synchronized with the image signal from the image processing unit 41 and the audio signal from the audio processing unit 45, and is sent to the drive signal generation unit 16. The

  When the biological information to be measured is a pulse, the drive signal generator 16 generates a drive signal S2 as shown in FIG. 2 to drive the playback device 25, and the biological information to be measured is breathed. In this case, the drive signal generator 16 generates the drive signal S3 or the drive signal S4 as shown in FIG.

  Therefore, in synchronization with the reproduction of the image and the sound, the pulse or breath of the subject 1 at the time of measurement recording is reproduced as content.

(2-2. Second Example: FIG. 5)
FIG. 5 shows a second example of the imaging recording / reproducing apparatus of the second embodiment.

  The imaging recording / reproducing apparatus 40 of this example is provided with the vibration motor 17, the red LED 18, and the blue LED 19 as a reproducing device for biological information as shown in FIG. The other differences are the same as those of the imaging recording / reproducing apparatus 30 in the example of FIG.

  Whether the vibration information is reproduced by the vibration motor 17, the red LED 18, or the blue LED 19 is set in advance depending on whether the biological information to be measured is a pulse or a breath, or the user operates the operation unit. 22 is selected.

  Specifically, when the biological information to be measured is a pulse, at the time of reproduction, the drive signal generation unit 16 generates a drive signal S2 as shown in FIG. 2 as a drive signal. Only the vibration motor 17, only the red LED 18, only the blue LED 19, the vibration motor 17 and the red LED 18, the vibration motor 17 and the blue LED 19, the red LED 18 and the blue LED 19, or the vibration motor 17, the red LED 18 and the blue LED 19 are driven.

Further, when the biological information to be measured is respiration, at the time of reproduction, for example, the drive signal generation unit 16 generates a drive signal S3 and a drive signal S4 as shown in FIG. Depending on user choice
(A) The red LED 18 is driven by the drive signal S3, and the blue LED 19 is driven by the drive signal S4.
(B) The blue LED 19 is driven by the drive signal S3, and the red LED 18 is driven by the drive signal S4.
(C) The vibration motor 17 and the red LED 18 are driven by the drive signal S3, and the blue LED 19 is driven by the drive signal S4.
(D) The vibration motor 17 and the blue LED 19 are driven by the drive signal S3, and the red LED 18 is driven by the drive signal S4.
And so on.

  As described above, when a plurality of playback devices are provided for biometric information, and the user can select a playback mode of biometric information from among a plurality of playback modes, the user can select a desired playback mode from time to time. You can select and enjoy playing back biometric information.

  Also in this example, the above-described telescopic device or the like can be used as one or a plurality of playback devices.

(2-3. Third Example: FIG. 6)
FIG. 6 shows a third example of the imaging recording / reproducing apparatus of the second embodiment.

  The imaging recording / reproducing apparatus in this example includes an imaging recording / reproducing apparatus body 50 and a measurement transmission apparatus 60.

  In this example, the target person 1 is a person who takes a picture with the imaging / recording / reproducing apparatus main body 50, and the target person 2 is a person who takes a picture with the imaging / recording / reproducing apparatus body 50.

  The imaging recording / reproducing apparatus main body 50 is obtained by adding a receiving unit 59 to the imaging recording / reproducing apparatus 30 in the example of FIG.

  The measurement transmission device 60 includes a biological sensor 61, an A / D converter 62, a feature amount detection unit 63, and a transmission unit 69 for measuring and transmitting the biological information of the subject 2.

  The biosensor 61 is, for example, a pulse sensor or a respiration sensor, like the biosensor 11 of the imaging recording / reproducing apparatus main body 50. However, the biosensor 11 and the biosensor 61 may both be pulse sensors, or both may be respiratory sensors, and one may be a pulse sensor and the other may be a respiratory sensor.

  In the feature amount detection unit 63, as shown in FIG. 2 or FIG. 3, depending on whether the biological sensor 61 is a pulse sensor or a respiration sensor, similarly to the feature amount detection unit 13 of the imaging recording / reproducing apparatus main body 50. The feature amount data of the subject 2 is detected and the feature amount data is generated.

  The generated feature amount data is transmitted from the transmission unit 69 of the measurement transmission device 60 to the imaging recording / reproducing device main body 50 by wireless communication using radio waves, infrared rays, or the like.

  The receiving unit 59 of the imaging / recording / reproducing apparatus main body 50 receives the feature amount data and sends it to the delay correcting unit 55, and the delay correcting unit 55 transmits the feature amount data to the feature amount of the imaging / recording / reproducing apparatus main unit 50. Similarly to the feature amount data from the detection unit 13, the demultiplexing unit 51 performs delay correction so as to synchronize with the compressed image data from the image processing unit 33 and the compressed audio data from the audio processing unit 39. To send.

  In this example, at the time of shooting and recording, the pulse or respiration of the subject 1 is measured by the biosensor 11, and at the same time, the pulse or respiration of the subject 2 is measured by the biosensor 61. Image data and audio data after compression of feature data of the first channel, which is feature data relating to pulse or respiration, and feature data of the second channel, which is feature data relating to the pulse or respiration of the subject 2 Are recorded on the recording medium 15.

  At the time of reproduction, the biological information of the channel selected by the user is reproduced. That is, at the time of reproduction, the feature amount data of the channel selected by the user separated by the multiplexing / separating unit 51 is subjected to delay correction by the delay correcting unit 55 and sent to the drive signal generating unit 16, and the drive signal generating unit In 16, the drive signal S2, the drive signal S3, or the drive signal S4 as described above is generated depending on whether the biological information of the measurement target of the channel is a pulse or a breath, and the playback device 25 is driven. The

  Therefore, in this example, the user can select one of the subject 1 and the subject 2, for example, the photographer and the person to be photographed, and reproduce the biological information of one of the subjects 1 and 2. The other biological information can be reproduced by switching to the other.

(2-4. Fourth example: FIG. 7)
FIG. 7 shows a fourth example of the imaging recording / reproducing apparatus of the second embodiment.

  The imaging recording / reproducing apparatus in this example includes an imaging recording / reproducing apparatus main body 70 and a measurement transmission apparatus 60, similarly to the imaging recording / reproducing apparatus in the example of FIG.

  In this example, the target person 1 is a person who takes a picture with the imaging / recording / reproducing apparatus main body 70, and the target person 2 is a person who takes a picture with the imaging / recording / reproducing apparatus main body 70.

  The imaging recording / reproducing apparatus main body 70 is obtained by adding a receiving unit 59 to the imaging recording / reproducing apparatus 40 in the example of FIG. The measurement transmitter 60 is the same as that shown in FIG.

  At the time of shooting and recording, the feature amount data obtained by the feature amount detection unit 63 of the measurement transmission device 60 and transmitted from the transmission unit 69 is received by the reception unit 59 of the imaging recording / playback device main body 70. The feature data of the first channel, which is the feature data related to the pulse or respiration of the subject, and the feature data of the second channel, which is the feature data related to the pulse or respiration of the subject 2, are compressed image data and sound. It is the same as the example of FIG. 6 that data is multiplexed and recorded on the recording medium 15.

  At the time of reproduction, the biological information of both channels is reproduced. That is, at the time of reproduction, the feature amount data of the first channel and the feature amount data of the second channel separated by the demultiplexing unit 51 are respectively subjected to delay correction by the delay correction unit 55 and sent to the drive signal generation unit 16. The drive signal generation unit 16 generates the drive signal S2, the drive signal S3, or the drive signal S4 as described above for each channel depending on whether the biological information of the measurement target of each channel is a pulse or a breath. Thus, the pulse or breath of the subject 1 is reproduced by a part of the vibration motor 17, the red LED 18 and the blue LED 19, and the pulse or breath of the subject 2 is reproduced by the other part.

  Therefore, in this example, at the time of shooting, the photographer and the photographed person were both nervous, and the photographer was nervous but the photographed person was calm. Or can be discovered.

  Regarding a playback device, when there are a plurality of viewers, a viewer who feels playback of biological information by touching like a vibration motor cannot feel at a time. In that case, a wireless means such as the measurement transmission device 60 used at the time of photographing described above is also used as a playback device so that a plurality of people can feel at the same time by the playback receiving device that receives a signal from the wireless means. Can be configured.

[3. Other embodiments of biometric information]
In the above embodiment, the pulse or respiration is measured and recorded and reproduced as the biological information. However, other biological information may be measured and recorded and reproduced.

  In this case, for example, the biological information of the measurement target is opposite to the pulse, and the time interval between adjacent peaks hardly changes, and the peak value (maximum value or minimum value) depends on the state of the subject. When it changes, the peak value of each peak is detected as the feature amount of the biological information, and is recorded and reproduced as feature amount data.

It is a figure which shows an example of the recording / reproducing apparatus of 1st Embodiment. It is a figure with which it uses for description when the biological information of a measuring object is a pulse.
