Description

  The present invention relates to a portable electronic device incorporating a tilt sensor.

  2. Description of the Related Art Conventionally, a portable electronic device such as a mobile phone has a built-in tilt sensor that measures a tilt angle of a main body and performs a control according to the tilt. In such a portable electronic device, by detecting the tilt of the main body with a tilt sensor, this can be used as input to various applications, control programs, etc., and various controls and effects such as light emission control and display image change can be performed. Is possible.

  For example, Patent Document 1 proposes a mobile phone that turns on a backlight when a state that is not a predetermined reference angle is changed to a reference angle.

  By the way, portable electronic devices often have a built-in vibration motor, and often notify the user of an incoming call or the arrival of a set time by vibration, or perform an effect together with music or sound effects.

  Here, when such vibration of the portable electronic device occurs during the measurement of the inclination angle, the inclination sensor detects this vibration as a change in the inclination angle. FIG. 1 is a diagram illustrating a change in a measured value of an inclination angle when a vibration motor of a stationary mobile phone is operated. In this way, the measurement value changes greatly due to the occurrence of vibration. As a result, the original inclination of the mobile electronic device cannot be detected correctly, which impedes production and control.

Therefore, proposals have been made to prevent such malfunction caused by vibration. For example, in Patent Document 2, as a preparation for identifying an operation pattern based on the acceleration of a mobile electronic device, it is confirmed whether or not a stationary state in which the acceleration of the mobile electronic device is equal to or less than a set threshold value has continued for a certain time. It has been shown that the operation pattern is identified after the stationary state lasts for a certain time.

  However, according to the method of Patent Document 2, for example, when acceleration exceeding a threshold value is generated due to vibration, it is necessary to wait for the vibration to stop in order to identify the operation pattern of the portable electronic device. In other words, in situations where acceleration other than the predetermined motion pattern is applied, such as vibration of the main body or acceleration from outside, motion pattern identification processing cannot be performed, so it operates in real time without waiting until it stops. The pattern cannot be identified.

  As described above, it has been difficult to detect the tilt of the main body, the operation pattern, and the like in real time without being affected by the disturbance for the production and control of the portable electronic device.

  Accordingly, an object of the present invention is to provide a portable electronic device that can detect an inclination angle from which disturbance has been removed in real time.

  Further, it is preferable that the determination unit determines the occurrence of the vibration by receiving a signal accompanied by driving of the device.

  The portable electronic device according to the present invention further includes a communication unit that receives a call signal for the device and performs communication based on the call signal, and the device is vibrated when the call signal is received. It is preferable that notification is performed and the determination unit determines the occurrence of the vibration based on occurrence of reception of the call signal.

  Further, it is preferable that the determination unit determines the occurrence of the vibration based on a similarity between the detection data and the pattern data.

  In addition, the storage unit stores pattern data of inclination changes caused by the vibration in a plurality of types of mounting states, respectively, and the portable electronic device according to the present invention is in a state where it is not determined that the vibration has occurred. And a mounting state determination unit that determines which of the plurality of types of mounting states is based on the detection state of the detection unit in the detection unit, wherein the removing unit is determined by the mounting state determination unit. It is preferable that the pattern data in the installed state is extracted from the storage unit, and the pattern data is removed from the detection data of the inclination angle by the detection unit after the occurrence of vibration.

  The portable electronic device according to the present invention further includes a reading unit that reads setting data indicating the generation timing of the vibration, and the removing unit detects the detection unit after the occurrence of the vibration based on the read setting data. It is preferable to remove the extracted pattern data from the detected inclination angle data.

  According to the portable electronic device of the present invention, the tilt angle from which the disturbance is removed can be detected in real time.

  FIG. 3 is a block diagram showing functions of the mobile phone 1. The mobile phone 1 includes an operation unit 11, a microphone 12, a main antenna 40, an RF circuit unit 41, an LCD control unit 42, an audio processing unit 43, a memory 44, an acceleration sensor 45, and a light emitting unit 46.

  In the present embodiment, the acceleration sensor 45 is used as the tilt sensor, and the tilt angle of the mobile phone 1 is calculated.

  The main antenna 40 communicates with an external device in a predetermined use frequency band (for example, 800 MHz). In the present embodiment, the predetermined use frequency band is 800 MHz, but other frequency bands may be used. Further, the main antenna 40 may have a so-called dual-band compatible configuration that can support other use frequency bands (for example, 2 GHz) in addition to a predetermined use frequency band.

  The RF circuit unit 41 demodulates the signal received by the main antenna 40, supplies the processed signal to the CPU 49, modulates the signal supplied from the CPU 49, and performs an external device (via the main antenna 40). To the base station). On the other hand, the CPU 49 is notified of the strength of the signal received by the main antenna 40.

  The LCD control unit 42 performs predetermined image processing according to the control of the CPU 49 and outputs the processed image data to the driver IC 23. The driver IC 23 stores the image data supplied from the LCD control unit 42 in the frame memory and outputs it to the LCD display unit 21 at a predetermined timing.

  The audio processing unit 43 performs predetermined audio processing on the signal supplied from the RF circuit unit 41 under the control of the CPU 49 and outputs the processed signal to the speaker 22. The speaker 22 outputs the signal supplied from the sound processing unit 43 to the outside.

  The audio processing unit 43 processes the signal input from the microphone 12 according to the control of the CPU 49 and outputs the processed signal to the RF circuit unit 41. The RF circuit unit 41 performs a predetermined process on the signal supplied from the sound processing unit 43 and outputs the processed signal to the main antenna 40.

  The memory 44 includes, for example, a working memory and is used for arithmetic processing by the CPU 49. Specifically, vibration pattern data to be described later can be stored. Note that the memory 44 may also serve as a removable external memory.

  The acceleration sensor 45 detects the acceleration given to the mobile phone 1 and outputs the detection result to the CPU 49. The acceleration sensor 45 is an example of a tilt detection unit.

  The acceleration sensor 45 is a three-axis (three-dimensional) type that detects acceleration in the X-axis direction, the Y-axis direction, and the Z-axis direction, and is based on an externally applied force (F) and mass (m). (A) is measured (acceleration (a) = force (F) / mass (m)).

  Further, the acceleration sensor 45 measures the force applied to a predetermined mass by a piezoelectric element to obtain the acceleration for each axis, converts it into numerical data, and buffers it. Then, the CPU 49 reads the acceleration data periodically buffered. The acceleration sensor 45 is not limited to a piezoelectric element (piezoelectric type), but may be a MEMS (Micro Electro Mechanical Systems) type such as a piezoresistive type, a capacitance type, a thermal detection type, or a feedback coil by moving a movable coil. And a servo gauge type that measures strain caused by acceleration with a strain gauge, or the like.

  The light emitting unit 46 is configured to emit light based on a voltage supplied from the power supply control circuit unit 47, and is configured by, for example, an LED (light emitting diode). In FIG. 3, for the sake of simplicity, a single light emitting unit 46 is shown, but actually, a plurality of different light emitting units are provided.

  The power supply control circuit unit 47 is connected to the rechargeable battery 50, converts the power supply voltage supplied from the rechargeable battery 50 into a predetermined power supply voltage, and supplies the converted power supply voltage to the light emitting unit 46 and the like. Of course, the power supply control circuit unit 47 supplies power to other electronic components and functional blocks.

  The CPU 49 controls the entire mobile phone 1, and in particular, performs predetermined control on the RF circuit unit 41, the LCD control unit 42, the sound processing unit 43, and a camera (not shown). Further, the CPU 49 monitors the internal state such as the radio wave state of the main antenna 40 described above, the remaining amount of the rechargeable battery 50, the presence of missed calls and unread mails, and based on this result, the light emitting unit 46 Control is also performed to change the emission color or change the display content of the LCD display unit 21.

  Further, when a calling signal for the device itself is detected by the RF circuit unit 41 as communication means, the LCD display unit 21, the light emitting unit 46, the vibration motor 48, and the speaker 22 are driven to notify the incoming call. When a response operation by the operation unit 11 occurs with respect to this incoming call, the RF circuit unit 41 is shifted to communication and a call.

  Here, operations of the acceleration sensor 45 and the CPU 49 will be described.

  The acceleration sensor 45 is supplied with a constant power supply voltage from the power supply control circuit, and periodically detects the change as acceleration data when the inclination of the mobile phone 1 changes. And CPU49 reads this. Further, the CPU 49 performs a predetermined calculation for obtaining the tilt angle for each of the three axes based on the read acceleration data, and grasps in which direction the mobile phone 1 is directed.

  The CPU 49 obtains the tilt angle of the mobile phone 1 from the acceleration data detected by the acceleration sensor 45, and controls the effects by the LCD display unit 21 and the light emitting unit 46 based on the tilt angle. For example, when an incoming call is received, a lighting location of a plurality of light emitting units 46 provided is determined according to an inclination angle, or a display image is changed according to the inclination angle in an application such as a game.

  Here, it is assumed that the acceleration sensor 45 mounted on the mobile phone 1 detects acceleration data in the three-axis directions of X, Y, and Z shown in FIG.

  FIG. 5 is a graph showing the transition of the tilt angle of the mobile phone 1 based on the acceleration data detected by the acceleration sensor 45. The inclination angle of each of the three axes changes substantially from the start of measurement, and then vibrates greatly by driving the vibration motor 48. For example, the tilt angle in the X direction starts to vibrate with an amplitude Ax after elapse of time tx, and the tilt angle in the Y direction starts to vibrate with an amplitude Ay after elapse of time ty.

  In this way, when vibration is generated by the vibration motor 48, fluctuation due to vibration is added to the inclination angle that should be measured. The CPU 49 removes the added fluctuation component by the method described below, and acquires the original tilt angle.

  First, the mobile phone 1 stores in advance the variation in the tilt angle caused by the vibration by the vibration motor 48 as a vibration pattern. At this time, since the vibration pattern varies depending on the mounting state of the mobile phone 1, vibration patterns in a plurality of states are stored.

  FIG. 6 is a list showing examples of vibration patterns for each mounting state stored in advance. Here, six types of states when the mobile phone 1 is placed on a desk are shown. That is, “1 g” or “−1 g” acceleration is applied in any of the X, Y, and Z directions, respectively, and “reference plane”, “90 ° right”, “90 ° left”, “90 ° front” ”,“ 90 ° back ”, and“ Reverse of reference plane ”are set.

  As the vibration patterns in the plurality of states, for example, the time tx until the vibration shown in FIG. 4 starts, the amplitude Ax during vibration, and the vibration period are stored. Then, when it is detected that a predetermined vibration starts, the stored vibration pattern is read and the difference from the actual measurement data is calculated to remove the fluctuation component and acquire the original tilt angle.

  Note that the vibration pattern to be stored is not limited to this, and for example, a difference in vibration pattern depending on the hardness of the place where the mobile phone 1 is placed may be stored. Or you may distinguish the state by which the operation part side housing | casing 2 and the display part side housing | casing 3 were opened mutually, and the folded state. As described above, by diversifying the types of vibration patterns to be stored, it is possible to effectively remove fluctuation components due to vibration.

  As described above, it is necessary to determine the vibration pattern to be read according to the situation from the vibration patterns stored in a plurality of types. However, based on the acceleration data acquired before the vibration occurs and the similarity to the tilt angle, the mobile phone One state can be identified.

  Alternatively, the vibration pattern to be removed may be determined based on the similarity between the actually measured acceleration and inclination angle transition and the stored vibration pattern. According to this, it is possible to cope with a case where the hardness of the place where the mobile phone 1 is placed is different or when the occurrence timing of vibration cannot be detected, and there is a possibility that an appropriate vibration pattern can be selected.

  The generation factor of vibration is not limited to the vibration motor 48 described above. For example, the removal method of the present embodiment can be applied as long as it can be stored as a vibration pattern, such as sounding of a speaker at the time of incoming call notification, zooming of the camera, button operation of the operation unit 11, and the like.

  In the present embodiment, the mobile phone 1 which is an example of the mobile electronic device has been described. However, the present invention is not limited to this, and for example, PHS (Personal Handyphone System), PDA (Personal Digital). An assistant), a portable navigation device, a notebook computer, or the like.

<Processing flow 1>
FIG. 7 is a flowchart showing processing in which the mobile phone 1 performs an incoming call effect according to the inclination when there is a predetermined vibration associated with an incoming call.

  In step S <b> 101, the CPU 49 acquires acceleration data detected by the acceleration sensor 45. This step is executed again after step S108 described later, and acceleration data is acquired at a predetermined cycle.

  In step S102, the CPU 49 determines whether an operation start signal for the vibration motor 48 is detected. If this determination is YES, it is determined that a new vibration has occurred, and the process proceeds to step S103. On the other hand, if the determination is NO, it is determined that there is no new vibration, and the process proceeds to step S104.

  For example, when the vibration timing is not constant, for example, when vibration is generated in conjunction with the incoming melody, by detecting the operation start signal in this way, processing according to the vibration timing can be performed.

  Here, the operation start signal of the vibration motor 48 is detected in order to determine that a new vibration has occurred, but the present invention is not limited to this. For example, the occurrence of vibration may be determined by acquiring a vibration mode setting that starts vibration in response to an incoming call. Alternatively, the start of vibration may be detected when the change in the acquired acceleration data exceeds a predetermined threshold.

  In step S <b> 103, the CPU 49 reads the vibration pattern stored in the memory 44. Here, a plurality of vibration patterns are stored as described above, and a suitable one is selected from them. Specifically, the most similar state is selected based on the acceleration data already acquired in step S101, and the corresponding vibration pattern is read.

  In step S104, the CPU 49 determines whether or not the vibration motor 48 is operating. If this determination is YES, vibration continues and the process moves to step S105. On the other hand, if this determination is NO, there is no vibration, and the process proceeds to step S106.

  In step S105, the CPU 49 removes the variation due to the vibration pattern read in step S103 from the acceleration data acquired in step S101. At this time, vibration starts after a predetermined time from the arrival of an incoming call, or after a predetermined time from the operation start signal of the vibration motor 48, and the vibration pattern is removed in accordance with this timing.

  In step S106, the CPU 49 determines the tilt angle of the mobile phone 1 based on the acceleration data acquired in step S101 or the acceleration data from which the vibration pattern is removed in step S105.

  In step S107, the CPU 49 performs an incoming call effect according to the inclination angle of the mobile phone 1 determined in step S106. Specifically, for example, effect control such as turning on one of the light emitting units 46 provided on the surface of the mobile phone 1 that is positioned above due to the inclination of the mobile phone 1 corresponds to this.

  In step S108, the CPU 49 determines whether the user has answered the phone. If this determination is YES, the effect of tilting the mobile phone 1 is terminated. On the other hand, when this determination is NO, in order to continue the effect, the process returns to step S101 and the acquisition of acceleration data is repeated.

  In this processing flow, the acquisition of acceleration data is started after an incoming call. However, the present invention is not limited to this, and may be continuously performed even when there is no incoming call.

  Further, in this processing flow, the event for performing the effect by the inclination and the event for starting the vibration are made common, but these events may be different from each other. For example, in an application such as a game, when control is performed to change the screen display according to the inclination angle of the mobile phone 1, if vibration occurs due to an incoming call, this processing flow is started by starting the application, Whether there is an incoming call is monitored in step S102. In step S108, the end of the application is determined.

<Processing flow 2>
FIG. 8 is a flowchart showing a process in which the mobile phone 1 performs an incoming call effect according to the inclination when a vibration that cannot immediately specify the vibration pattern occurs in response to the incoming call.

  The mobile phone 1 stores a plurality of types of vibration patterns assumed in advance. When it is determined that the vibration as a disturbance has occurred due to the change in acceleration data periodically detected by the acceleration sensor 45 exceeding a predetermined threshold, a plurality of stored vibration patterns are used one by one. Then, it tries to remove the vibration from the detected acceleration data.

  As a result, if the change in the acceleration data falls within the threshold, it is determined that the vibration has been removed, and the vibration pattern at this time is considered to correspond to the vibration that has actually occurred, and the subsequent acceleration data Continue to eliminate vibration.

  On the other hand, if the change in the acceleration data still does not fall within the threshold even after trying to remove the vibration, it is determined that the vibration pattern used is different from the vibration that is actually occurring, Attempts to eliminate vibrations using vibration patterns. The vibration pattern is specified by trying one by one in this way. Hereinafter, the processing steps will be described in order.

  In step S201, the CPU 49 clears the vibration pattern previously read and used, and prepares for the specification of the vibration pattern.

  In step S202, the CPU 49 acquires acceleration data detected by the acceleration sensor 45. This step is executed again after step S211 described later, and obtains acceleration data at a predetermined cycle.

  In step S203, the CPU 49 determines whether or not the change amount of the acceleration data periodically acquired in step S202 exceeds a predetermined threshold value. If this determination is YES, it is determined that vibration has occurred as a disturbance, and the process proceeds to step S204. On the other hand, if the determination is NO, it is determined that there is no disturbance and the process proceeds to step S209.

  In step S204, the CPU 49 determines whether there is a read vibration pattern. If this determination is YES, the vibration pattern has not been cleared, and the process proceeds to step S206. If the determination is NO, the process proceeds to step S205.

  In step S205, the CPU 49 newly reads one from a plurality of stored vibration patterns. At this time, when all the vibration patterns have already been read, the vibration pattern is cleared and the process proceeds to the next step S206.

  In step S206, the CPU 49 determines whether or not the vibration pattern has been read. If this determination is YES, the process proceeds to step S207 to determine the suitability of the read vibration pattern. On the other hand, if the determination is NO, since an appropriate vibration pattern could not be determined, the process proceeds to step S209 without correcting the acceleration data.

  In step S207, the CPU 49 corrects the acceleration data acquired in step S202 by removing the variation due to the vibration pattern in order to determine the suitability of the vibration pattern read in step S205.

  In step S208, the CPU 49 determines whether or not the acceleration data corrected in step S207 has exceeded a predetermined threshold as in step S203. If this determination is YES, it is determined that the fluctuation component of acceleration due to vibration cannot be removed because the read vibration pattern does not match the vibration that is actually generated, and the process returns to step S205. On the other hand, when the determination is NO, since the fluctuation component of acceleration due to vibration is similar to the vibration pattern, it is determined that the disturbance has been removed by this vibration pattern, and the process proceeds to step S209.

  In steps S207 to S208, the degree of similarity between the fluctuation component of the acquired acceleration data and the read vibration pattern is determined. Here, in order to prevent erroneous determination due to instantaneous similarity, the past acceleration data for a predetermined period is corrected by the same vibration pattern, and it is determined whether or not the change exceeds a threshold value.

  In step S209, the CPU 49 determines the tilt angle of the mobile phone 1 based on the acceleration data acquired in step S202 or the acceleration data from which the vibration pattern is removed in step S207.

  In step S210, the CPU 49 performs an incoming call effect according to the inclination angle of the mobile phone 1 determined in step S209.

  In step S211, the CPU 49 determines whether or not the user has answered the phone. If this determination is YES, the effect of tilting the mobile phone 1 is terminated. On the other hand, when this determination is NO, in order to continue the effect, the process returns to step S202, and the acquisition of acceleration data is repeated.

  Here, a plurality of stored vibration patterns are sequentially read one by one to attempt to remove vibrations, but the present invention is not limited to this. For example, each vibration pattern may be stored together with each vibration pattern, and a vibration pattern that matches or approximates the vibration period of the detected acceleration data may be selected and read. Thereby, a vibration pattern can be specified efficiently.

  According to this processing flow, even if the vibration pattern is unknown, an appropriate vibration pattern is selected by comparing the detected acceleration data with the vibration pattern stored in advance, and the fluctuation amount of acceleration due to vibration is selected. May be removed.

  Note that steps S203 to S208 can be omitted when it is detected that vibration does not occur by acquiring the vibration mode setting for starting vibration in response to an incoming call.

  The procedure for correcting the acceleration data detected by the acceleration sensor 45 with the predetermined vibration pattern according to the processing flow 1 and the processing flow 2 has been described above. Here, the correction target is not limited to acceleration data, and the tilt angle calculated by the CPU 49 may be corrected.

  Furthermore, in this embodiment, the inclination angle detection means is the acceleration sensor 45 and the CPU 49, and the CPU 49 calculates the inclination angle based on the acceleration data detected by the acceleration sensor 45. The tilt angle detection means is not limited to this, and may be realized by various sensors as long as the tilt sensor measures the tilt angle and outputs it to the CPU 49.

  Moreover, although this embodiment demonstrated the presentation control by detecting the inclination-angle of the mobile telephone 1, it is not restricted to this. By using the acceleration sensor 45, it is possible to detect a transition of acceleration in a state other than the stationary state, and for example, it is possible to identify a predetermined operation pattern, determine a fall, and the like.

  In the case of identifying a predetermined motion pattern, the step of determining the inclination angle in the processing flow 1 and the processing flow 2 is replaced with processing for matching with a transition pattern of acceleration indicating the predetermined motion pattern. Further, in the case of determining fall, the step of determining the inclination angle is replaced with processing for determining whether or not the acceleration has become zero or a minute value.

  Thereby, when a disturbance having a vibration pattern stored in advance, such as vibration by the vibration motor 48, is applied, the disturbance can be removed, and the operation pattern and the tilt angle of the mobile phone 1 can be determined.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
