Embodiment 1
First, the operation of the mobile terminal 1 according to the first embodiment will be briefly described. (A)-(f) of Drawing 2 is a figure showing an example of operation of personal digital assistant 1 concerning this embodiment. The operation of the mobile terminal 1 shown in FIG. 2 is merely an example, and the comment displayed by the mobile terminal 1 and the sound output from the mobile terminal 1 are not limited to the example shown in FIG.

«Operation example of mobile terminal»
As shown in (a) to (b) of FIG. 2, it is assumed that the curtain in the room in which the portable terminal 1 is placed is in the opened state from the closed state, and light is inserted into the room. As described above, when the area around the portable terminal 1 is rapidly brightened, the portable terminal 1 displays on the display unit 40 a comment 100 that responds to the change in the peripheral illumination, as shown in FIG. In addition to the display of the comment 100, the portable terminal 1 may output at least one of a voice corresponding to the comment or the comment, BGM (Back Ground Music), and a sound effect from the speaker 50.

  On the other hand, as shown in (d) to (e) of FIG. 2, it is assumed that the surroundings of the portable terminal 1 become bright as time passes from night to morning. Thus, when the ambient illumination of the portable terminal 1 changes slowly, the portable terminal 1 does not perform comment display and speech as shown in (c) of FIG. 2 as shown in (f) of FIG.

  As described above, the portable terminal 1 performs different output control depending on whether the area around the own terminal is brightened rapidly or slowly. In addition, it will be described later which degree of change is determined to be "rapid" or "slow". Hereinafter, a configuration for the portable terminal 1 to realize the output control according to the change of the peripheral illuminance will be described.

«Main part composition»
FIG. 1 is a block diagram showing the main configuration of the mobile terminal 1. As illustrated, the portable terminal 1 includes a light control IC (integrated circuit) (notification unit) 20, an illuminance sensor 30, a control unit (control device) 10, a display unit 40, and a speaker 50.

  The illuminance sensor 30 detects the peripheral illuminance according to an instruction of the illuminance sensor control unit 12 (described later) of the control unit 10, and transmits a detection value to the illuminance sensor control unit 12.

  The dimming IC 20 is an integrated circuit for illuminance detection which is driven with lower power consumption than the illuminance sensor 30. The dimming IC 20 constantly monitors (voluntarily or according to an instruction from the control unit 10) whether or not the ambient illumination is equal to or higher than the first threshold, and detects that the ambient illumination has become equal to or higher than the first threshold, The notification detection unit 11 is notified of the detection result. The first threshold may be set, for example, to the illuminance (about 250 lux) under fluorescent light of the living space such as a living room or a bedroom. Moreover, the dimming IC 20 may be realized by a configuration other than the integrated circuit. For example, it may be composed of a light detection element and a comparator, or it may be composed of a light detection element and an A / D converter, and comparison of whether or not it is a first threshold or more may be performed by software. Further, the dimming IC 20 and the illuminance sensor 30 may be disposed anywhere in the mobile terminal 1 as long as the peripheral illuminance can be detected appropriately.

  The control unit 10 controls the mobile terminal 1 in an integrated manner, and is realized by a CPU (Central Processing Unit). More specifically, the control unit 10 includes a threshold storage unit 14, a notification reception unit 11, an illuminance sensor control unit (detection instruction unit) 12, a determination unit 13, and a device control unit 15.

  The threshold storage unit 14 stores a first threshold. Note that FIG. 1 shows an example in which the threshold storage unit 14 is realized by the internal memory of the control unit 10. However, the threshold storage unit 14 may be realized by an external memory of the control unit 10.

  The notification receiving unit 11 receives a notification from the dimming IC 20. Specifically, when the notification receiving unit 11 receives a notification indicating that the ambient illumination has become higher than the first threshold, the notification receiving unit 11 instructs the illumination sensor control unit 12 to start the illumination sensor 30. The illuminance sensor control unit 12 activates the illuminance sensor 30 according to the instruction of the notification receiving unit 11, and causes the illuminance sensor 30 to detect the peripheral illuminance. The illuminance sensor control unit 12 also acquires the detection value of the illuminance sensor 30 and sends it to the determination unit 13.

  The determination unit 13 determines whether or not the magnitude of the difference between the detection value of the illuminance sensor 30 and the first threshold stored in the threshold storage unit 14 is equal to or greater than a predetermined value. The determination unit 13 determines that “the area around the portable terminal 1 has become bright rapidly” if the magnitude of the difference is equal to or greater than a predetermined value, and “portable” if the magnitude of the difference is less than the predetermined value. It is determined that the area around the terminal 1 has become brighter slowly. The determination unit 13 sends the determination result to the device control unit 15. Details of the predetermined value will be described later.

  The device control unit 15 controls at least one of the screen display of the display unit 40 and the audio output of the speaker 50 according to the determination result of the determination unit 13. In the present embodiment, when the determination unit 13 determines that “the area around the portable terminal 1 has become bright rapidly”, the device control section 15 determines that the area around the portable terminal 1 is slowly brightened ”. Control different from the case. Specifically, when the device control unit 15 receives from the determination unit 13 a determination result indicating that “the periphery of the mobile terminal 1 has become bright rapidly”, the device control unit 15 responds to the change in the peripheral illumination on the display unit 40. A comment (such as the comment 100 in (c) of FIG. 2) is displayed. In addition, the device control unit 15 may cause the speaker 50 to output at least one of voice, BGM, and sound effect corresponding to the comment. On the other hand, when the device control unit 15 receives from the determination unit 13 a determination result indicating that “the area around the portable terminal 1 has been brightened slowly”, the display control of the comment and the output control of the voice, BGM, and sound effect are performed. Do not do.

  The display unit 40 displays an image according to the control of the device control unit 15. Although the kind of display part 40 is not specifically limited, For example, it is realizable with a liquid crystal display etc. The speaker 50 outputs sound according to the control of the device control unit 15.

(Change in ambient illumination and judgment result)
Next, setting of a predetermined value which is a determination reference of the determination unit 13 will be described with reference to FIG. FIG. 3 is a diagram showing the relationship between the degree of change in the ambient illumination and the first threshold value and the detection value of the illumination sensor 30. As shown in FIG. (A) of FIG. 3 shows the change of the illuminance when the area around the portable terminal 1 becomes bright rapidly (for example, when changing from (a) to (b) of FIG. 2), and (b) of FIG. It shows the change of the illuminance when the area around the terminal 1 is brightened slowly (for example, when changing from (d) to (e) in FIG. 2).

  As shown in (a) and (b) of FIG. 3, when the periphery of the portable terminal 1 becomes brighter than the first threshold, the dimming IC 20 detects that the peripheral illumination has become the first threshold or more at t1. . Thereafter, at t2, the illuminance sensor 30 detects the illuminance. Then, the determination unit 13 determines whether or not the difference a1 between the first threshold and the detected illuminance is equal to or greater than a predetermined value. A time lag may or may not be provided from the detection of the light adjustment IC 20 to the detection of the illuminance of the illuminance sensor 30, that is, from t1 to t2.

  As illustrated, the difference a1 is when the area around the portable terminal 1 is brightened more rapidly than when the area around the portable terminal 1 is brightened slowly ((b) in FIG. 3) ((a) in FIG. 3) Is larger. Therefore, by appropriately setting the predetermined value, the determination unit 13 can determine whether or not the area around the portable terminal 1 has become bright rapidly. More specifically, the predetermined value may be set to, for example, about 170 lux. The determination unit 13 may determine the degree of change in brightness around the mobile terminal 1 in two or more stages. For example, two predetermined values may be provided, and it may be determined from the magnitude of the difference a1 that "slightly brightened", "relatively rapidly brightened", and "rapidly brightened".

«Flow of detection process of illuminance change»
Lastly, the detection process of the change of the illuminance in the portable terminal 1 according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing a flow of processing for detecting a change in illuminance in the mobile terminal 1 according to the present embodiment.

  The dimming IC 20 constantly monitors whether the ambient illumination has become equal to or higher than the first threshold (S10). Then, when the dimming IC 20 detects that the peripheral illumination has become equal to or higher than the first threshold (YES in S10), it transmits a notification indicating that the peripheral illumination has become equal to or higher than the first threshold to the notification receiving unit 11. When receiving the notification (S12, notification receiving step), the notification receiving unit 11 instructs the illuminance sensor control unit 12 to drive the illuminance sensor 30. When the illumination sensor control unit 12 receives the instruction, the illumination sensor control unit 12 drives the illumination sensor 30, and acquires a detection value of the illumination sensor 30 (S14, detection instruction step). The illuminance sensor control unit 12 sends the acquired detected value to the determination unit 13.

  When the determination unit 13 receives the detection value of the illumination sensor 30 from the illumination sensor control unit 12, the determination unit 13 reads the first threshold stored in the threshold storage unit 14. Then, the determination unit 13 determines whether the magnitude (difference a1 in FIG. 3) of the difference between the detection value and the first threshold is equal to or greater than a predetermined value (S16), and sends the determination result to the device control unit 15.

  If the magnitude of the difference between the detected value and the first threshold is greater than or equal to the predetermined value (YES in S16), the determination unit 13 determines that the periphery of the portable terminal 1 has become bright rapidly, and the device control unit 15 determines the determination Control according to (S18, device control step). Specifically, the device control unit 15 causes the display unit 40 to display a comment that responds to a change in brightness, and causes the speaker 50 to output a voice related to the comment ((c) in FIG. 2).

  On the other hand, if the magnitude of the difference between the detected value and the first threshold is less than the predetermined value (NO in S16), the determination unit 13 determines that the periphery of the portable terminal 1 has become brighter slowly, and the device control unit 15 Control according to the determination is performed (S20, device control step). In this case, the device control unit 15 receiving the determination result does not perform any special control on the display unit 40 and the speaker 50. Specifically, in the case of NO in S16, the device control unit 15 does not instruct the display unit 40 and the speaker 50 to output a comment or sound in response to the brightness change ((f) in FIG. 2).

  According to the above processing, the illuminance sensor 30 detects the value of the brightness when the value of the brightness changes to the first threshold or more. In other words, since the illuminance sensor 30 does not have to perform the illuminance detection until the above-described trigger occurs, it is possible to reduce the power consumption for driving. Therefore, while reducing the power consumption related to the detection of the brightness change in the vicinity of the mobile terminal 1, the mobile terminal 1 changes the brightness (whether the area around the mobile terminal 1 is rapidly brightened or slowly brightened). The electronic device can be controlled according to the

Second Embodiment
The mobile terminal 1 according to the present invention may determine whether the periphery of the mobile terminal 1 has become dark rapidly or slowly dark, and may control the display unit 40 and the speaker 50 according to the determination result. Hereinafter, Embodiment 2 of the present invention will be described using FIGS. 5 to 6. In addition, about the member which has the same function as the member demonstrated in Embodiment 1 for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

  The threshold storage unit 14 according to the present embodiment stores a second threshold. The second threshold may be set to about 250 lux similar to the first threshold. The dimming IC 20 according to the present embodiment detects that the peripheral illumination has become equal to or less than the second threshold, and notifies the notification receiving unit 11 of the same. When receiving the notification, the notification receiving unit 11 instructs the illuminance sensor control unit 12 to activate the illuminance sensor 30.

  The determination unit 13 determines whether or not the magnitude of the difference between the second threshold value and the detection value of the illuminance sensor 30 is greater than or equal to a predetermined value. If the magnitude of the difference is greater than or equal to the predetermined value It is determined that the periphery has become dark rapidly, and if it is less than the predetermined value, it is determined that the periphery of the portable terminal 1 has become dark slowly.

  The device control unit 15 controls the display unit 40 and the speaker 50 according to the determination result. For example, when the determination unit 13 determines that “the area around the portable terminal 1 has become dark suddenly”, the device control unit 15 displays a comment that responds to the change in illuminance on the display unit 40 and the comment on the speaker 50. And / or BGM and / or sound effects. For example, the device control unit 15 assumes that the above-mentioned change in illumination is caused by turning off the room electricity, and displays a comment such as "Are you setting an alarm for tomorrow morning?" Or "A good dream!" And the contents of the comment may be output by voice. On the other hand, when the determination unit 13 determines that “the area around the mobile terminal 1 has become dark slowly,” the device control unit 15 does not display the comment or output voice.

«Change in ambient illumination and judgment result»
FIG. 5 is a diagram showing the relationship between the degree of change of the ambient illumination and the second threshold and the detection value of the illumination sensor 30. As shown in FIG. (A) of FIG. 5 shows the change of the illuminance when the area around the portable terminal 1 is suddenly darkened, and (b) of FIG. 5 shows the change of the illuminance when the area around the portable terminal 1 is getting dark slowly There is.

  As shown in (a) and (b) of FIG. 5, when the area around the portable terminal 1 becomes dark, the light adjustment IC 20 detects that the area illumination has become equal to or higher than the second threshold at t3. Thereafter, at t4, the illuminance sensor 30 detects the illuminance. Then, the determination unit 13 determines whether or not the difference a2 between the second threshold and the detected illuminance is equal to or greater than a predetermined value. As in t1 and t2 of the first embodiment, a time lag may or may not be provided from t3 to t4.

  As illustrated, the difference a2 is the case where the periphery of the portable terminal 1 becomes darker than that in the case where the periphery of the portable terminal 1 becomes dark slowly ((b) in FIG. 5) ((a) in FIG. 5) Is larger. Therefore, by appropriately setting the above predetermined value, the determination unit 13 can determine whether or not the ambient illumination has sharply decreased. Note that, also in the present embodiment, the determination unit 13 may determine the degree of change in brightness around the portable terminal 1 in two or more steps.

«Detection processing of change in illuminance»
Finally, the detection process of the change of the illumination in the portable terminal 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing a flow of processing for detecting a change in illuminance in the mobile terminal 1 according to the present embodiment. The processes of S32 and S34 are the same as the processes of S12 and S14 in FIG.

  The dimming IC 20 constantly monitors whether the ambient illumination has become equal to or less than the second threshold (S30). Then, when the peripheral illumination becomes equal to or less than the second threshold (YES in S30), the dimming IC 20 transmits, to the notification receiving unit 11, a notification indicating that the peripheral illumination has become equal to or lower than the second threshold. When the notification receiving unit 11 receives the notification (S32), the notification receiving unit 11 instructs the illuminance sensor control unit 12 to drive the illuminance sensor 30. When the illumination sensor control unit 12 receives the instruction, the illumination sensor control unit 12 drives the illumination sensor 30, and acquires the detection value of the illumination sensor 30 (S34). The illuminance sensor control unit 12 sends the acquired detected value to the determination unit 13.

  When the determination unit 13 receives the detection value of the illumination sensor 30 from the illumination sensor control unit 12, the determination unit 13 reads the second threshold stored in the threshold storage unit 14. Then, the determination unit 13 determines whether the magnitude (difference a2 in FIG. 5) of the difference between the detection value and the second threshold is equal to or greater than a predetermined value (S36), and sends the determination result to the device control unit 15.

  If the difference between the detected value and the second threshold is greater than or equal to the predetermined value (YES in S36), the determination unit 13 determines that the periphery of the portable terminal 1 has become dark rapidly, and the device control unit 15 determines the determination Control according to (S38). Specifically, the device control unit 15 causes the display unit 40 to display a comment that responds to a change in brightness, and causes the speaker 50 to output a voice related to the comment.

  On the other hand, when the magnitude of the difference between the detected value and the second threshold is less than the predetermined value (NO in S36), the determination unit 13 determines that the periphery of the portable terminal 1 has become dark slowly, and the device control unit 15 Control according to the determination is performed (S40). Specifically, the device control unit 15 does not perform special control (display control of a comment that responds to a change in brightness and output control of sound) on the display unit 40 and the speaker 50.

  According to the above processing, the illuminance sensor 30 detects the value of the brightness when the value of the brightness changes to the second threshold or less. In other words, since the illuminance sensor 30 does not have to perform the illuminance detection until the above-described trigger occurs, it is possible to reduce the power consumption for driving. Therefore, while reducing the power consumption for detecting the change in brightness around the mobile terminal 1, the mobile terminal 1 changes the brightness (the area around the mobile terminal 1 suddenly becomes darker or it gets darker slowly). The electronic device can be controlled according to the

Third Embodiment
The determination unit 13 may determine whether or not the magnitude of the difference between the detection value of the illuminance sensor 30 and the first threshold or the second threshold is within a predetermined range. Then, the device control unit 15 may perform different control on the display unit 40 and the speaker 50 depending on whether or not the change in the peripheral illumination is within a predetermined range. Specifically, when the determination unit 13 determines that the magnitude of the difference is within the predetermined range, the device control unit 15 causes the display unit 40 to display a comment that responds to the brightness change, The sound relating to the comment may be output from the speaker 50. When the determination unit 13 determines that the magnitude of the difference is outside the predetermined range, the device control unit 15 does not display the comment on the display unit 40 and does not output the sound to the speaker 50. May be

  Furthermore, in the case of the present embodiment, the “predetermined range” is, for example, the case where there is a change in illuminance due to the flickering of the indoor light, such as the change in illuminance shown in (a) to (b) of FIG. It is desirable that the magnitude of the above difference of is defined to be included in the range. On the other hand, in the above "predetermined range", when the surface on which the light adjustment IC 20 and the illuminance sensor 30 are disposed is covered (or the cover is lost), the entire portable terminal 1 does not have difference in light such as pocket or wrinkles It is desirable that the magnitude of the above-mentioned difference in the case where there is a sudden change in the peripheral illumination, such as when it is taken out of the dark place, be defined to be out of range. Alternatively, the values of the first threshold and the second threshold may be set so that the above-mentioned "predetermined range" falls within the above-described desirable range. Thereby, the portable terminal 1 can judge the brightness change of the periphery more finely, and can control the comment display, the utterance, and the like.

[Modification]
The process of the mobile terminal 1 described in the first embodiment may be performed in combination with the process described in the second embodiment. Specifically, the dimming IC 20 constantly determines whether or not the ambient illumination has become equal to or higher than a predetermined threshold, and when the determination result changes (that is, the predetermined ambient illumination is less than the predetermined threshold). If the peripheral illumination is equal to or greater than a predetermined threshold is less than the predetermined threshold), the determination result may be notified to the notification receiving unit 11. Then, when the notification receiving unit 11 receives a notification that the peripheral illuminance has reached the predetermined threshold or more, the control unit 10 may perform the processing described in the first embodiment. Further, when the notification receiving unit 11 receives a notification that the peripheral illuminance has become less than the predetermined threshold, the control unit 10 may perform the processing described in the second embodiment.

  In the above embodiments, the device control unit 15 performs control of comment display on the display unit 40 and control of sound output of the speaker 50 according to the determination result of the determination unit 13. However, the control target of the device control unit 15 is not limited to the display unit 40 and the speaker 50. For example, the device control unit 15 may control the drive of the camera provided in the portable terminal 1 according to the determination result of the determination unit 13, that is, the change amount of the peripheral illumination, or the portable terminal realized by the control unit 10 One of various functions (alarm function, adjustment function of luminance of display unit 40, volume adjustment function of speaker 50, etc.) may be controlled.

[Example of software implementation]
The control block (in particular, the notification receiving unit 11, the illuminance sensor control unit 12, the determination unit 13, and the device control unit 15) of the control unit 10 is realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like. It may be realized by software using a CPU (Central Processing Unit).

  In the latter case, the control unit 10 is a CPU that executes an instruction of a program that is software that realizes each function, a ROM (Read Only Memory) in which the program and various data are readably recorded by a computer (or CPU) or A storage device (these are referred to as a "recording medium"), a RAM (Random Access Memory) for developing the program, and the like are provided. The object of the present invention is achieved by the computer (or CPU) reading the program from the recording medium and executing the program. As the recording medium, a “non-transitory tangible medium”, for example, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit or the like can be used. The program may be supplied to the computer via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.

[Summary]
A control device (control unit 10) according to aspect 1 of the present invention is a control device that controls an electronic device (portable terminal 1) including an illuminance sensor (illuminance sensor 30), and detects the peripheral illuminance of the electronic device And a notification receiving unit (notification receiving unit 11) for receiving a notification from the notification unit, and the notification receiving unit receiving the notification from the notification unit from the notification unit. A detection instruction unit (illumination sensor control unit 12) that causes the illuminance sensor to detect the illuminance around the electronic device when the notification that the threshold is the first threshold or more is received, the illuminance detected by the illuminance sensor, and the And a device control unit (device control unit 15) configured to control the electronic device in accordance with the magnitude of the difference with the one threshold value.

  A control method according to aspect 7 of the present invention is a control method of an electronic device (portable terminal 1) including an illuminance sensor (illuminance sensor 30), which detects peripheral illuminance of the electronic device and a detection result.

And equipment control steps (S18 and S20) to control.

  According to the above configuration, the detection instruction unit causes the illuminance sensor to detect the value of the brightness when the value of the brightness changes to the first threshold or more. In other words, the illuminance sensor may not detect the illuminance until the above-mentioned trigger occurs.

  By the way, specifying whether or not the ambient illuminance exceeds a specific threshold (the first threshold in the above configuration) can be realized with lower power consumption than when the illuminance is constantly detected quantitatively by an illuminance sensor or the like ( For example, a light control IC). Therefore, according to said structure, power consumption can be reduced rather than the case where illumination intensity is always detected by an illumination intensity sensor. Therefore, the control device can control the electronic device according to the change in the brightness while reducing the power consumption related to the detection of the change in the brightness.

  In the control device according to aspect 2 of the present invention, in the above aspect 1, when the magnitude of the difference is equal to or larger than the predetermined value, the device control unit is different from the case where the magnitude of the difference is smaller than the predetermined value Control may be performed on the electronic device.

  According to the above configuration, the device control unit can change the control of the electronic device depending on whether the periphery of the electronic device has become bright (or dark) with a change amount equal to or more than a predetermined value. Therefore, the electronic device can be controlled in accordance with the illuminance around the electronic device.

  In the control device according to aspect 3 of the present invention, in the above aspect 1, when the magnitude of the difference is within the predetermined range, the magnitude of the difference is outside the predetermined range. Control different from the above may be performed on the electronic device.

  According to the above configuration, the device control unit may change the control of the electronic device depending on whether the amount of change in brightness around the electronic device is within the predetermined range or outside the range. it can. Therefore, the control device can judge the brightness change around the electronic device more finely and control the electronic device.

  In the control device according to aspect 4 of the present invention, in any one of the aspects 1 to 3, the device control unit determines at least one of display of an image or output of sound in the electronic device as the magnitude of the difference. It may be controlled according to

  According to the above configuration, the control device can cause the electronic device to display an image or output sound in accordance with a change in brightness around the electronic device. For example, the control device can display a comment or output a sound in response to a change in brightness around the electronic device.
