Description

  The present invention relates to an electronic device, a control method thereof, and a program, and more particularly, to an electronic device including a proximity sensor, a control method thereof, and a program thereof.

  In recent years, electronic devices such as mobile phones often use a touch panel as an input interface. This is because an intuitive operation of touching a desired object with a fingertip while visually recognizing an object such as a button on the display screen through the touch panel can be performed. There was a drawback in that an unintended operation was performed because a cheek or ear touched the touch panel during a call.

In order to eliminate this drawback, a technique using a proximity sensor (hereinafter referred to as related technique) is known (see the following patent document).
Here, the proximity sensor is a general term for detecting the proximity of an object (human or object) or the presence or absence of a nearby detection target without contact. From the detection principle, an inductive type, a capacitance type, an ultrasonic type , Photoelectric type, magnetic type, etc. (JIS C 8201-5-2: low-voltage switchgear and control device / part 5 control circuit equipment and switchgear / second-node proximity switch).

  In the related art, the operation of the touch panel is invalidated when an object is detected within the detection distance (generally 0 to several cm) of the proximity sensor. For this reason, an unintended touch operation during a call can be prevented.

The ROM 20b may be a rewritable nonvolatile semiconductor memory (Programmable Read Only Memory: PROM).

Next, the proximity sensor 5 will be described in detail.
As described at the beginning, there are various types of proximity sensors 5 such as an induction type, a capacitance type, an ultrasonic type, a photoelectric type, and a magnetic type. Any kind of proximity sensor 5 may be used in the concept of the invention. Here, a photoelectric type is used as an example.

  FIG. 3 is a block diagram of the proximity sensor 5. The proximity sensor 5 includes a light emitting element 24 using an infrared light emitting LED (Light Emitting Diode) and the like, and a sensor integrated circuit (Optical IC) 25. The sensor integrated circuit 25 includes an interface unit 26 that performs bidirectional data exchange with the control unit 20, and interrupts the control unit 20 at a required timing. The register unit holds the setting data 28a from the control unit 20, the detection data 28b of the proximity sensor 5 and the like. 28, an oscillation unit 29 that oscillates a signal of a predetermined frequency in accordance with setting data 28a held in the register unit 28, and light emission in accordance with a signal from the oscillation unit 29 and setting data 28a held in the register unit 28. A timing control unit 30 that generates each timing signal of light reception, and an infrared light drive signal based on the output of the timing control unit 30 Drive signal generation unit 31, light emission drive unit 32 that drives the light emitting element 24 in response to the drive signal, a photodiode or a cadmium sulfide (CdS) cell that is a kind of optical electrical converter (Optical Electrical Converter), etc. And an analog / digital conversion unit (Analog Digital) that converts the output of the amplifier 34 into a digital signal and stores it in the register unit 28 as detection data 28b. Converter: ADC) 35.

  When the detection data 28b (output data of the ADC 35) is stored in the register unit 28, the interrupt unit 27 interrupts the control unit 20 in response to the storage, and the control unit 20 responds to the interrupt. Then, the detection data 28 b (the output data of the ADC 35) stored in the register unit 28 is read via the interface unit 26.

  As described above, the register unit 28 holds the setting data 28a and the detection data 28b. The detection data 28b is output data of the ADC 35, and in short, is data corresponding to the magnitude of the amount of light received by the light receiving element 33. On the other hand, the setting data 28a is various control data appropriately set by the control unit 20 in order to define the operation of the proximity sensor 5. The setting data 28a includes at least the timing of light reception / emission (light emission / reception). Timing setting data 28c for defining the length, repetition cycle, etc.) and detection distance setting data 28c for defining the detection distance of the proximity sensor 5.

  In general, when the proximity sensor 5 is used for the purpose of “preventing unintentional touch operation” described at the beginning, the detection distance of the proximity sensor 5 is very short (about 0 cm to 2 cm or 0 cm to 3 cm). Close contact of cheeks and ears is detected at 0 cm, and approach of cheeks and ears is detected at 2 to 3 cm. Hereinafter, this short detection distance is referred to as a “first detection distance”. In the proximity sensor 5 of the present embodiment, the detection distance is added to the “first detection distance”, and further to the “second detection distance” for detecting a far person (for example, 1 m to 2 m) or an object. Can be set. That is, when the “first detection distance” is set in the detection distance setting data 28d of the register unit 28, the proximity sensor 5 detects a person or an object at a distance of 0 cm to 2 cm or 0 cm to 3 cm, and sets the detection distance. When the “second detection distance” is set in the data 28d, the proximity sensor 5 detects a person or an object at a distance of 1 to 2 m.

  FIG. 4 is a diagram showing a mounting structure of the proximity sensor 5. In this figure, the light emitting element 24 and the light receiving element 33 of the proximity sensor 5 are fixedly mounted on a substrate 36 provided inside the mobile phone 1. Both the light emitting element 24 and the light receiving element 33 are covered with transparent resins 37 and 38, and an infrared light shielding wall 39 is provided between the light emitting element 24 and the light receiving element 33. The light emitting direction of the light emitting element 24 and the light receiving direction of the light receiving element 33 are substantially parallel. The infrared light Pa from the light emitting element 24 is irradiated in the vertical direction of the main surface 2a through the infrared light transmission window 40 that forms a part of the main surface 2a of the housing 2. The infrared light Pb reflected by the object 41 (human or object) passes through the infrared light transmission window 40 and is received by the light receiving element 33, and detection data 28 b corresponding to the received light amount is sent to the register unit 28 of the proximity sensor 5. It is supposed to be saved.

  The flow of object detection using the proximity sensor 5 is as follows. First, the infrared light Pa is emitted from the light emitting element 24 toward the object 41, the reflected light Pb from the object 41 is received by the light receiving element 33, converted into an electric signal, amplified by the amplifier 34, and digitalized by the ADC 35. The value is converted into a value, and the digital value is stored in the register unit 28 as detection data 28b. Next, the detection data 28b is taken into the control unit 20, and the control unit 20 checks whether or not the size of the detection data 28b exceeds a predetermined threshold. If the detection data 28b exceeds the threshold, the proximity of the object 41 is determined. To do.

  The detection distance of the proximity sensor 5 is determined solely by the light amount of the light emitting element 24 and the threshold value used by the control unit 20. Increasing the amount of light increases the detection distance, and decreasing the amount of light decreases the detection distance. Further, when the threshold value is lowered, the detection distance becomes longer, and when the threshold value is raised, the detection distance becomes shorter. As described above, the proximity sensor 5 of the embodiment can be selectively used at two detection distances (a first detection distance and a second detection distance). This selective use may be performed by any one of the increase / decrease control of the light emission amount of the light emitting element 24 and the control of the threshold value, or may be performed by a combination thereof, but the latter combination is practically used. Is desirable. This is because the amount of emitted light has a certain upper limit due to physical restrictions and legal restrictions, and if the threshold is too low, false detection increases due to the influence of noise or the like.

  Therefore, in practice, a combination of changing the threshold value and adjusting the light amount of the light emitting element 24 is realistic. In other words, when used at the “first detection distance”, the light amount of the light emitting element 24 of the proximity sensor 5 is set to “first light amount”, and the threshold value of the control unit 20 is set to “first threshold value”. , When used at the “second detection distance”, the light amount of the light emitting element 24 of the proximity sensor 5 is set to be a “second light amount” larger than the first light amount, and the threshold value of the control unit 20 is set to the first threshold value. It is practical to set the “second threshold value” smaller than the threshold value. However, the concept of the embodiment is not limited to this. If both the “first detection distance” and the “second detection distance” can be achieved by controlling the light amount of the light emitting element 24, it is not necessary to change the threshold value, or the “first detection distance” can be changed by changing the threshold value. The light quantity of the light emitting element 24 does not need to be changed as long as both of “” and “second detection distance” can be achieved.

  FIG. 5 is a diagram showing a schematic flow of a control program executed by the CPU 20 a of the control unit 20. This control program is repeatedly executed at a predetermined short cycle by the CPU 20a while the power of the mobile phone 1 is on.

  When this control program is started, the CPU 20a first determines whether or not the operation mode of the mobile phone 1 is set to a predetermined mode (hereinafter referred to as a warning mode) (step S11). Here, one of the uses of the proximity sensor 5 is to prevent an unintended operation of the touch panel 3 as described at the beginning. This application is called “normal use”. On the other hand, the alert mode refers to a mode for using the proximity sensor 5 for another use different from the normal use, and this use is referred to as a “crime prevention use”.

The alert mode is intentionally set by the user (user) of the mobile phone 1.
FIG. 6 is a diagram illustrating a setting example of the alert mode. For example, the user who wants to set the alert mode presses and holds one of the physical buttons (here, the central physical button 9 as an example). When the control unit 20 detects a long press of the physical button 9 (YES in step S100), the control unit 20 sets the operation mode of the mobile phone 1 to “warning mode” (step S101) and also displays a required message 4a on the display unit 4. Is displayed to notify the user that the alert mode has been set (step S103). Similarly, the warning mode may be canceled by long-pressing the physical button 9.

<Normal use>
Returning to FIG. 5 again, when the alert mode is not set (NO determination in step S11), the CPU 20a sets the detection distance of the proximity sensor 5 to the “first detection distance” (step S12), and the proximity sensor 5, the detection data 28b is taken in, and the detection data 28b is compared with a predetermined threshold (first threshold) to determine whether or not the detection data 28b, that is, the amount of light received by the light receiving element 33 exceeds the first threshold. Is determined (step S13). If it does not exceed, the operation of the touch panel 3 is enabled (step S14), and the flow ends. If it exceeds, the operation of the touch panel 3 is disabled (step S15) and the flow ends. Thereby, an unintended touch operation when a cheek, an ear, or the like touches or comes close to the touch panel 3 can be prevented.

<Security use>
On the other hand, if the alert mode is set (YES determination in step S11), the CPU 20a sets the detection distance of the proximity sensor 5 to a “second detection distance” that is longer than the “first detection distance” (step S11). S16), the detection data 28b is fetched from the proximity sensor 5, and the detection data 28b is compared with a predetermined threshold value (second threshold value smaller than the first threshold value) to detect the detection data 28b, that is, the light receiving element 33. It is determined whether the amount of received light exceeds a second threshold (step S17). If it does not exceed, the predetermined warning process (details will be described later) is not executed, or if it is being executed, the warning process is stopped (step S18), and the flow is terminated. Is started (step S19), and the flow is terminated.

Various predetermined alert processes can be considered. For example, the following (1) to (3) may be used.
(1) Detecting that the object 41 has approached the “second detection distance”, automatically issuing information to a preset registration destination, sending a pre-recorded voice as an incoming call response, and carrying it A warning process that tells that the object 41 has approached the telephone 1. As a result, it is possible to realize a crime prevention function in a place where humans and objects are not originally accessible. If e-mail is used as a means for transmitting automatic notification, it is possible to automatically transmit a document set in advance to the registered e-mail address. For example, if the mobile phone 1 set in the alert mode is placed in the car, it is possible to detect the intrusion of the suspicious person into the car and notify the registration destination by e-mail or voice. In this case, the vehicle body shake may be detected using the acceleration sensor 22 or the magnetic sensor 23. Even when the proximity sensor 5 enters from the blind spot, the intrusion can be detected from the shaking of the vehicle body.

(2) Detecting that the object 41 has approached the “second detection distance”, taking a still image or a moving image with the front camera 7 or the rear camera 12 of the mobile phone 1, and storing the captured image in the memory unit 18. Warning process to save. It is desirable to use a camera (front camera 7 in the embodiment) that matches the detection direction of the proximity sensor 5 as the camera to be used. The warning process (1) may be performed in parallel with the shooting and recording of the moving image. Further, the moving image information may not be stored in the memory unit 18, but may be stored on a network server via a communication function, or may be viewed from a remote terminal via a network. Further, similarly to the warning process (1), the acceleration sensor 22 and the magnetic sensor 23 may be used to detect shaking, and may be used together with the output of the proximity sensor 5 to determine human feeling.

(3) Warning processing in which it is detected that the object 41 has approached the “second detection distance” and the camera light 12a of the mobile phone 1 is turned on. Thus, for example, when an emergency situation (earthquake or fire, etc.) is encountered while sleeping at night, emergency lighting can be obtained by holding a hand or the like toward the proximity sensor 5 of the mobile phone 1. Evacuation behavior can be performed quickly and safely.

  As described above, according to the mobile phone 1 of the first embodiment, the “normal use” in which one proximity sensor 5 prevents an unintended operation of the touch panel 3 and the proximity of an object or a person to the mobile phone 1 are prevented. Since it can be used for two purposes of “crime prevention use” of monitoring, it is possible to provide the mobile phone 1 with further improved convenience.

  In addition, since the use of these two applications does not require hardware changes and can be performed solely by improving the control program, it is easy and costly to use various electronic devices with built-in proximity sensors. There is also a peculiar advantage that it can be applied easily.

  In addition, application of embodiment is not restricted to a mobile phone or a smart phone. The present invention can also be applied to other devices (for example, game machines, tablet PCs (Personal Computers), notebook PCs, PDAs (Personal Data Assistants: personal digital assistants), or digital cameras.
