Note that the urgency is a priority set from a viewpoint different from the priority set for each mobile terminal device 2. When the degree of urgency is high, even brightness control information from the mobile terminal device 2 with low priority is transmitted to the room lighting device 5. On the other hand, when the degree of urgency is low, whether or not transmission to the room lighting device 5 is possible is determined based on the priority of the mobile terminal device 2 that has transmitted the brightness control information. When the degree of urgency is high, for example, the room lighting device 5 immediately turns off or lights up at the maximum brightness, or turns on in a predetermined pattern. On the other hand, when the degree of urgency is low, the room lighting device 5 gradually changes the brightness at, for example, a predetermined change rate.

Note that transmission / reception of information by the communication unit 40 and the communication unit 50 may be performed wirelessly or may be performed by wire.

  The calculation unit 51 controls the brightness (luminance) of the illumination unit 52 based on the brightness control information. For this reason, the calculation unit 51 generates a control signal based on the brightness control information and outputs the control signal to the illumination unit 52. In addition, the calculation unit 51 outputs information (Ack information) indicating that the brightness control information has been received to the communication unit 50.

  The illumination unit 52 is, for example, LED illumination, and performs indoor illumination with brightness according to a control signal from the calculation unit 51.

  Note that the interior lighting control device 4 and the interior lighting device 5 are not divided in configuration, and may be configured as an integral unit.

  FIG. 7 is a flowchart showing a flow of processing executed by the mobile terminal device 2 in the brightness control processing according to the present embodiment. This process starts when the mobile terminal device 2 is activated. Further, even when the brightness control process is being performed, the measurement by the screen angle measurement unit 27 is continuously performed.

  First, in step 100, the screen orientation determination unit 33 determines whether or not the casing 10 of the mobile terminal device 2 is held by the user based on the measurement result by the screen angle measurement unit 27. 102.

  In step 102, the screen orientation determination unit 33 determines whether or not the tilt of the LCD screen is within the screen downward range based on the measurement result by the screen angle measurement unit 27. If the determination is affirmative, the process proceeds to step 104. If NO, the process returns to step 100.

  In Step 104, the brightness control unit 34 transmits the brightness control information for reducing the luminance of the lighting device 3 (the lighting unit 52) via the communication unit 23. Thereby, when the brightness of the illumination device 3 is lowered, the brightness of the LCD screen can be made higher than the brightness of the illumination device 3, so that the user can easily see the LCD screen.

  The brightness control information may indicate, for example, a predetermined luminance, or may indicate a luminance control amount determined by the user.

  FIG. 8 shows an image (hereinafter referred to as “brightness control interface image”) 60 displayed on the touch panel display 11 for the user to determine the brightness control amount of the lighting device 3. The brightness control interface image 60 is controlled by the user via the touch sensor 11B. In the brightness control interface image 60, for example, the brightness of the lighting device 3 can be set by the user moving the arrow image 60A up and down. In the present embodiment, the luminance of the lighting device 3 is not changed in the state where the arrow image 60A is positioned at the top. On the other hand, when the position of the arrow image 60A is lowered by the user, the luminance of the illumination device 3 is lowered.

  The brightness control unit 34 transmits brightness control information indicating luminance according to the position of the arrow image 60 </ b> A via the communication unit 23.

  Note that the brightness control interface image 60 is not limited to the one shown in FIG.

  In the next step 106, based on the measurement result by the screen angle measurement unit 27, the screen orientation determination unit 33 determines whether or not the casing 10 of the mobile terminal device 2 is held by the user. The process proceeds to step 108. If the determination is negative, the process proceeds to step 110.

  In step 108, based on the measurement result by the screen angle measurement unit 27, the screen orientation determination unit 33 determines whether the inclination of the LCD screen is within the screen downward range. In the case of an affirmative determination, the process returns to step 106 and the state where the luminance of the lighting device 3 is lowered is maintained. On the other hand, if a negative determination is made, the process proceeds to step 110.

  When the process proceeds to step 110, the user lies down while holding the mobile terminal device 2, and is not in an attitude of viewing the LCD screen while facing up. For this reason, in step 110, the brightness control unit 34 transmits brightness control information for returning the luminance of the lighting device 3 via the communication unit 23. Note that returning the luminance means that the luminance before transmitting the brightness control information in step 104 is set.

  FIG. 9 is a flowchart showing a flow of processing executed by the room lighting device 5 in the brightness control processing according to the present embodiment.

  In step 200, the calculation unit 51 determines whether or not brightness control information has been received via the communication unit 40. If the determination is affirmative, the process proceeds to step 202.

  In step 202, the calculation unit 51 determines whether or not the priority set in advance for each portable terminal device 2 that has transmitted the brightness control information is high. If the determination is affirmative, the operation proceeds to step 204, and a negative determination is made. If so, return to Step 200.

  The indoor lighting device 5 may control the brightness based on the priority set in advance for each mobile terminal device 2. For example, priority is given to the brightness control information from the mobile terminal device 2 having a high priority set in advance. To control the brightness. Note that the priority is not set for each portable terminal device 2, and the room lighting device 5 may control the luminance according to the latest received brightness control information.

  In step 204, the calculation unit 51 controls the luminance of the illumination unit 52 based on the brightness control information, and the process returns to step 200. Thereby, the brightness control process controls the luminance of the lighting device 3.

  As described above, the lighting control system 1 according to the present embodiment includes the portable terminal device 2 and the indoor lighting device 5 capable of controlling the brightness. The portable terminal device 2 transmits brightness control information for reducing the brightness of the lighting device 3 to the lighting device 3 when the housing 10 is held by the user with the LCD screen facing downward. And the illuminating device 3 controls the brightness of illumination based on the received brightness control information.

  The brightness control unit 34 according to this embodiment is determined by the screen orientation determination unit 33 to be held by the user with the LCD screen facing downward, and, for example, the brightness comparison unit 36 causes the screen luminance to be on the back side. When it is determined to be darker than the side illuminance, the brightness control information is transmitted to the communication unit 23. The case where the screen brightness is darker than the back side illuminance is when the periphery is brighter than the LCD screen and the LCD screen is difficult to see.

If the determination is affirmative, the process proceeds to step 103. If NO, the process returns to step 100.

  In step 103, the brightness comparison unit 36 determines whether the screen luminance is darker than the back side illuminance. If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process returns to step 100. Since the dimension differs between luminance and illuminance, in step 103, for example, the luminance or illuminance is converted using a conversion formula or a conversion coefficient, and the magnitude relationship between the screen luminance and the back side illuminance is determined.

  In step 104, the brightness control unit 34 transmits brightness control information for reducing the luminance of the lighting device 3 via the communication unit 23. As a result, the surrounding area becomes darker than the LCD screen, so that the user can easily see the LCD screen. If the difference between the back side illuminance and the screen brightness is equal to or greater than a predetermined value and the back side illuminance is too bright compared to the screen brightness, the brightness control unit 34 communicates the brightness control information with a high degree of urgency. You may make it transmit to the part 23.

  In the next step 106, the screen orientation determination unit 33 determines whether or not the inclination of the LCD screen is within the screen downward range. If the determination is affirmative, the process proceeds to step 108. If the determination is negative, the process proceeds to step 110. Transition.

  In step 108, based on the measurement result by the screen angle measuring unit 27, the screen orientation determining unit 33 determines whether or not the inclination of the LCD screen is within the screen downward range. If the determination is affirmative, the process returns to step 106. If the determination is negative, the process proceeds to step 110.

  In step 110, the brightness control unit 34 transmits brightness control information for returning the luminance of the lighting device 3 via the communication unit 23.

If the determination is affirmative, the process proceeds to step 302. When the brightness suppression function operates, the brightness of the LCD screen decreases and the brightness of the lighting device 3 relatively increases, so that it is difficult for the user to view the LCD screen.

  In step 302, the brightness control unit 34 transmits brightness control information for reducing the luminance of the lighting device 3 via the communication unit 23. Thereby, when the brightness of the illumination device 3 is lowered, the brightness of the LCD screen can be made higher than the brightness of the illumination device 3, so that the user can easily see the LCD screen.

  In the next step 304, the operation function determination unit 38 determines whether or not the brightness suppression function continues to operate. If the determination is negative, the process proceeds to step 306. The negative determination is, for example, a case where the battery capacity is such that the brightness suppression function can be canceled by charging the battery 29.

  In the next step 306, the brightness control unit 34 transmits brightness control information for returning the luminance of the lighting device 3 via the communication unit 23.

  FIG. 14 is a flowchart showing a flow of processing executed by the mobile terminal device 2 in the brightness control processing corresponding to the camera function according to the present embodiment. Note that the brightness control process corresponding to the camera function is executed regardless of the priority even if the priority is set in the mobile terminal device 2.

  First, in step 400, the operation function determination unit 38 determines whether or not the camera function is operating. If the determination is affirmative, the process proceeds to step 402.

  In step 402, the camera 13 measures subject illuminance.

  In the next step 404, the subject illuminance determination unit 32 determines whether the subject illuminance is suitable for imaging. If the determination is affirmative, the process proceeds to step 406. If the determination is negative, the process proceeds to step 408. . The case where the illuminance of the subject is not appropriate includes a case where the room is too dark and underexposed, a case where the room is too bright and overexposed, and the illumination device 3 is located behind the subject and is backlit. .

  In step 406, since the subject illuminance is brightness suitable for imaging, imaging processing by the camera 13 is performed according to the user's operation, and the process returns to step 400.

  In step 408, since the subject illuminance is not suitable for imaging, the brightness control unit 34 transmits brightness control information via the communication unit 23. That is, when the subject illuminance determination unit 32 determines that the exposure is insufficient, the mobile terminal device 2 transmits brightness control information for increasing the luminance. On the other hand, when the subject illuminance determination unit 32 determines that the subject is overexposed, the mobile terminal device 2 transmits brightness control information for reducing the luminance. As a result, the room has a brightness suitable for imaging by the camera 13.

  In the next step 410, imaging processing by the camera 13 is performed according to the user's operation.

  In the next step 412, the brightness control unit 34 determines whether or not the photographing is finished. If the determination is affirmative, the process proceeds to step 414.

  In the next step 414, the brightness control unit 34 transmits brightness control information for returning the luminance of the lighting device 3 via the communication unit 23. As described above, since the photographing is finished and the luminance of the illumination device 3 is returned, the illumination device 3 operates like a flash when the exposure is insufficient.

  FIG. 15 is a flowchart showing a flow of processing executed by the mobile terminal device 2 in the brightness control processing corresponding to the projector function according to the present embodiment.

  First, in step 500, the operation function determination unit 38 determines whether or not the projector function is operating. If the determination is affirmative, the process proceeds to step 502.

  In step 502, the brightness control unit 34 transmits brightness control information for reducing the luminance of the lighting device 3 via the communication unit 23. As a result, the room becomes dark with the operation of the projector function, so that the user can easily see the image projected by the projector.

  In the next step 504, the operation function determination unit 38 determines whether or not the projector function is operating. If the determination is negative, the process proceeds to step 506.

  In the next step 506, the brightness control unit 34 transmits brightness control information for returning the luminance of the lighting device 3 via the communication unit 23.

  Here, the illumination interlocking function is not limited to the brightness suppression function, the camera function, and the projector function, but may be other functions.

  For example, the mobile terminal device 2 may use an off-timer function that turns off the power of the mobile terminal device 2 after a predetermined time has elapsed as the illumination interlocking function. Specifically, the portable terminal device 2 transmits brightness control information so that the lighting device 3 is turned off after the time set by the off timer function has elapsed. Alternatively, the mobile terminal device 2 transmits brightness control information for gradually decreasing the brightness of the lighting device 3 so that the mobile terminal device 2 is turned off after the set time has elapsed. Moreover, the portable terminal device 2 may use an alarm function as an illumination interlocking function, and may change the luminance of the lighting device 3 with a predetermined brightness (for example, maximum luminance) or a constant lighting pattern by an alarm operation. Moreover, the portable terminal device 2 uses the reception function of emergency earthquake warning, emergency disaster information, etc. as an illumination interlocking function, and when these are received, the brightness of the lighting device 3 is set to a predetermined brightness or a fixed lighting pattern. It may be changed with. Further, the mobile terminal device 2 uses the incoming call function of the telephone as an illumination interlocking function, and when there is an incoming call with the lighting device 3 turned off, the luminance of the lighting device 3 is set to a predetermined brightness or a constant lighting. You may change by a pattern.

  Further, the mobile terminal device 2 may use a so-called night shift mode that cuts off blue light emitted from the LCD 11A at night as the illumination interlocking function. Specifically, the mobile terminal device 2 transmits brightness control information for switching the brightness color of the lighting device 3 to a warm color system in conjunction with the night shift mode.

  In addition, when the camera function is operating, the mobile terminal device 2 may not only operate the lighting device 3 like a flash but also switch the brightness color of the lighting device 3. For example, the mobile terminal device 2 transmits brightness control information for switching colors according to the color of the focused portion in order to improve the reproducibility of the photographed photograph. More specifically, the mobile terminal device 2 transmits brightness control information for switching the brightness color of the lighting device 3 to a warm color system when the focus is on a human face or food.

  As described above, the mobile terminal device 2 according to the present embodiment transmits brightness control information to the lighting device 3 in accordance with the operating lighting interlocking function. Thereby, the illumination control system 1 can make the brightness of the room illumination appropriate according to the usage state of the mobile terminal device 2, that is, the function operating in the mobile terminal device 2.
