Therefore, the CCD camera 22 captures the face of the user P standing in front of the mirror of the main mirror door 12 as a camera provided in the mirror cabinet 3 as the vanity main body.

  FIG. 3 shows the configuration of the control system of the washstand 1. In FIG. 3, reference numeral 23 denotes a lighting button provided in the operation box 7, and the lighting button 23 is formed of an on / off switch. An operation signal of the illumination button 23 is output to the controller 24. The controller 24 and the CCD camera 22 are connected so as to be able to transmit and receive signals.

  The controller 24 comprises a microcomputer and the like. The controller 24 uses human body information such as facial expressions of the user P's face (for example, an expression of yawning with an open mouth) and eye conditions (for example, the number of blinks or the average closing time per blink) taken by the CCD camera 22. It has the determination part 25 which determines a user's awakening degree based on it. Further, the controller 24 is configured to change at least one of the illuminance and the color temperature of the illumination devices 17 and 18 according to the awakening degree determined by the determination unit as a control unit. Each of the lighting devices 17 and 18 includes light emitting units 17a and 18a each made of an LED or the like, and circuit units 17b and 18b capable of changing at least one of the illuminance and the color temperature of the light emitting units 17a and 18a. . When the color temperature of the light emitting units 17a and 18a is changed, for example, a plurality of types of LEDs having different emission colors are used as the light emitting units 17a and 18a, and LEDs emitting light are selected according to the color temperature. Just do it.

  The control contents of the lighting devices 17 and 18 by the controller 24 are performed according to the flowchart shown in FIG.

  That is, after waiting for the lighting button 23 to be turned on in step S1, it is determined in step S2 whether or not the current time is the preset morning time zone (for example, 8:00 am to 12:00 am). The internal clock of the controller 24 is used for this time determination.

  When the time determination is YES, the lighting devices 17 and 18 are turned on in the wake mode in step S3, and the wake lighting subroutine is executed in step S4.

  In the awakening illumination subroutine, according to the flowchart shown in FIG. 5, first, the face of the user P standing in front of the mirror of the main mirror door 12 is photographed and recognized by the CCD camera 22 in step S11. This captured image is as shown in FIG. 6, and recognizes, among the faces of the user P, in particular, a portion (for example, the position of an eye) R of human body information to be obtained.

  Subsequently, in step S12, moving images of the face, in particular, moving images of eyes are photographed, and in step S13, for example, an average closing eye time per blink is detected as human body information.

  Next, in step S14, the awakening degree of the user P is determined based on the average closed eye time. A characteristic chart showing the relationship between the average closing time and the awakening degree as shown in FIG. 7 is used for this determination. In this characteristic diagram, the awakening degree is lower as the average closing time is longer.

  Thereafter, in step S15, at least one of the illuminance and the color temperature of the lighting devices 17 and 18 is changed according to the awakening degree. In the present embodiment, the color temperature of the lighting devices 17 and 18 in the wake mode is fixed at 7000 K, and only the illuminance of the lighting devices 17 and 18 is changed. At that time, a characteristic chart showing the relationship between the awakening degree and the illuminance as shown in FIG. 8 is used. In this characteristic diagram, the illuminance is lower as the awakening level is higher. FIG. 9 is a characteristic diagram showing a preferable specific example of the relationship between the average closing eye time and the illuminance. In this characteristic graph, the illuminance is 500 Lx when the average closing eye time is 120 msec, and the illuminance is larger as the average closing eye time is longer. It's getting higher.

  Thus, the awakening illumination subroutine is completed once, and this subroutine is repeated once a minute while lighting in the awake mode.

  When lighting in the wake mode in step S3 is continued, it is determined in step S5 whether or not the time zone is out of the morning due to the passage of time. When this determination is other than the morning time zone of YES, it changes to lighting of normal mode at Step S6, and while it shifts to Step S7, when it is the morning time zone of determination NO, it transfers to Step S7. The lighting in the normal mode will be described later.

  In step S7, it is determined whether or not the illumination button 23 is switched off. When the determination is NO, the process returns to step S3. On the other hand, when the determination is YES, the illumination devices 17 and 18 are extinguished in step S8. Finish.

  On the other hand, when the time determination in step S2 is outside the morning time zone of NO, the lighting devices 17 and 18 are lit in the normal mode in step S9. In the normal mode, the color temperature of the lighting devices 17 and 18 is 4000 K, and the illuminance is 300 to 400 Lx.

  Subsequently, in step S10, it is determined whether or not the illumination button 23 is switched off. When the determination is NO, the process returns to step S9, while when the determination is YES, the process proceeds to step S8 and the illumination device 17, Turn off 18 and end control.

  As described above, the vanity table (vanity vanity table) 1 includes a vanity table body (mirror cabinet) 3 having a mirror (mirrors of mirror doors 12 to 14) and a lighting device 17 for illuminating the user P in front of the mirror. , 18 and a camera (CCD camera) 22 for photographing the face of the user P. The lighting devices 17 and 18 and the camera 22 are all provided in the dressing table body 3. Further, the dressing table 1 determines the awakening degree of the user P based on the human body information of the user P photographed by the camera 22, and the lighting device 17 according to the awakening degree determined by the determination unit 25. And a control unit (controller) that changes at least one of the illuminance and the color temperature. The human body information of the user P includes the facial expression of the face and the state of the eyes.

  According to such a dressing table 1, the awakening degree of the user P is determined based on the human body information of the user P in front of the mirror photographed by the camera 22, and the illuminance and color of the lighting devices 17 and 18 are accordingly determined. Change at least one of the temperatures. For this reason, the awakening degree of the user P can be effectively enhanced without giving the user P discomfort due to the excessive awakening action.

  In particular, in the case of the present embodiment, the control unit 24 is provided to perform change control (lighting in the awake mode) according to the awakening degree only in a preset morning time zone (S1 to S1 in FIG. 4). See S6). For this reason, it is possible to prevent the change control according to the awakening degree from being performed during the morning time zone due to the user's erroneous operation, and it is possible to improve the reliability of the operation.

  Moreover, the dressing table main body 3 is a mirror cabinet which has the opening / closing mirror door 12-14 in a front surface. A half mirror 21 is provided on a part of the mirror of the mirror door (main mirror door) 12, and the camera 22 is inside the mirror cabinet 3 through the half mirror 21 when the mirror door 12 is closed. It is possible to take pictures.

  In such a configuration, the user P is less likely to be aware of the presence of the camera 22 on the mirror cabinet 3 side, and the function as the dressing table 1 is not impaired. In addition, since the face of the user P standing in front of the mirror door 12 can be photographed from almost directly in front by the camera 22, acquisition of the human body information of the user P based on this photographing and consequently the alertness of the user P The determination can be made properly, and the operation reliability can be further enhanced.

  Furthermore, in performing change control according to the awakening degree of the user P, only the illumination intensity of the illuminating devices 17 and 18 was changed, and the color temperature was fixed at 7000K. For this reason, it is not necessary to use a plurality of types of LEDs or the like having different emission colors for the light emitting portions 17a and 18a of the lighting devices 17 and 18 as in the case of changing the color temperature of the lighting devices 17 and 18. It is advantageous in planning.

  The present invention is not limited to the first embodiment but includes various other embodiments. For example, when the camera 22 is provided in the mirror cabinet 3 as the dressing table main body, the configuration as in the second embodiment shown in FIG. 10 may be used instead of the configuration as in the first embodiment.

  That is, in the second embodiment, a camera 22 for photographing the face of the user standing in front of the mirrors of the mirror doors 12 to 14 at the center position in the width direction of the front end face of the upper wall portion of the cabinet body 11 of the mirror cabinet 3 Provide Further, upper lamps 31 as illumination devices are provided at the left and right positions of the front end face of the upper wall of the cabinet body 11 across the camera 22.

  In the first embodiment, the awakening degree is determined based on the average closed eye time separately from the detection of the average closed eye time as human body information from the moving image of the face of the user P photographed by the camera 22; At least one of the illuminance and the color temperature of the lighting devices 17 and 18 is changed according to the awakening degree. However, since the average closing time has a close relationship with the arousal, the present invention detects the average closing time as the arousal level, and at least the illuminance and color temperature of the illumination devices 17 and 18 according to the average closing time. One of them may be changed. Therefore, the alertness referred to in the present invention means not only the alertness in a narrow sense but also a broader alertness including human body information having a close relationship with the alertness such as the average eye closing time.

  Furthermore, of course, the present invention can be applied not only to the vanity unit 1 as in the first and second embodiments but also to other vanity units and vanity units.
