Description

[0001] This application is a divisional application of Chinese national application number 2022101789048, with an application date of February 25, 2022. Technical Field

[0002] The invention relates to a pointer display action control device, a pointer display device, a pointer display action control method and a storage medium. Background Art

[0003] There is a pointer display device that moves a pointer to display a relative position of the pointer relative to a mark or scale, etc., and a pointer operation mode, etc. The pointer performs a stepping operation by a stepping motor, etc. Therefore, in a fast-forward operation that continuously performs a stepping operation to change the display content, it may take time to complete the display change depending on the number of stepping operations, etc.

[0004] In analog clocks and the like, which are pointer display devices that display the time, various processes are performed at a low clock frequency to perform long-term continuous operations with low power consumption. However, as a pointer display device that performs driving and the like involved in the fast-forward operation of the pointer, if a process with a slightly larger load is further performed in parallel with other processes with a larger load such as communication processing, the total load may become too large. Therefore, there is a technology that staggers the processing timings of multiple processes so that they do not overlap at the same time (for example, Japanese Patent Laid-Open No. 2011-33430). Summary of the invention

[0005] In pointer display devices, due to the recent multi-functionality and high performance, sometimes processing cannot be completed quickly with the previous clock frequency. However, if the clock frequency is uniformly increased, the processing load and power consumption will increase, and there is a problem that it is difficult to continue the operation for a long time as in the past.

[0006] An object of the present invention is to provide a pointer display operation control device, a pointer display device, a pointer display operation control method, and a program that can achieve a desired improvement in processing performance while suppressing an increase in power consumption.

[0007] In order to achieve the above object, the present invention provides a pointer display control device, which includes a control unit, and the control unit performs the following control:

[0008] A first processing circuit capable of executing processing for moving a pointer according to a first frequency signal outputs the first frequency signal or the second frequency signal by switching an oscillating unit that outputs the first frequency signal and a second frequency signal having a frequency higher than the first frequency signal.

[0009] controlling whether or not the second frequency signal is output to a second processing circuit, wherein the second processing circuit performs a predetermined processing according to the second frequency signal,

[0010] controlling the switching of the oscillation circuit that switches and outputs the first frequency signal and the second frequency signal according to the presence or absence of the certain processing,

[0011] During the period when the second processing circuit performs the certain processing, the specific operation of the pointer performed by the first processing circuit is prohibited

[0012] The present invention also provides a pointer display device, comprising: a pointer; a first processing unit, which can execute processing for moving the pointer according to a first frequency signal; a second processing unit, which performs a predetermined processing according to a second frequency signal having a frequency higher than that of the first frequency signal; an oscillating unit, which switches and outputs the first frequency signal and the second frequency signal; and a control unit, which controls the switching of the frequency signal output by the oscillating unit according to the presence or absence of the certain processing, and prohibits the specific movement of the pointer performed by the first processing unit during the period when the second processing unit performs the certain processing.

[0013] The present invention also provides a pointer display action control method, the method comprising the following steps:

[0014] A first output step, for a first processing unit capable of executing a process for moving a pointer according to a first frequency signal, outputting the first frequency signal or the second frequency signal by switching the output of the first frequency signal and a second frequency signal having a frequency higher than the first frequency signal through an oscillating unit;

[0015] a second output step of controlling whether or not the second frequency signal is output to a second processing unit, wherein the second processing unit performs a predetermined processing according to the second frequency signal;

[0016] a frequency control step of controlling the switching of the oscillating unit according to the presence or absence of the certain processing; and

[0017] The specific action prohibition step prohibits the first processing unit from performing the specific action of the pointer while the second processing unit is performing the certain process.

[0018] The present invention also provides a non-transitory computer-readable storage medium storing a program that enables a computer to function as the following unit:

[0019] a first output unit, which outputs the first frequency signal or the second frequency signal by switching an oscillating unit that outputs the first frequency signal and a second frequency signal having a higher frequency than the first frequency signal to a first processing unit that can execute a process for moving a pointer according to the first frequency signal;

[0020] a second output unit for controlling whether or not the second frequency is output to a second processing unit, wherein the second processing unit performs a predetermined processing according to the second frequency signal;

[0021] a frequency control unit that controls the switching of the oscillating unit according to the presence or absence of the certain processing; and

[0022] A specific operation prohibition unit prohibits the specific operation of the pointer performed by the first processing unit while the second processing unit is performing the certain process.

[0023] According to the present invention, in the pointer display control device, there is an effect that a desired improvement in processing performance can be achieved while suppressing an increase in power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0029] Figure 1 It is a plan view of an electronic timepiece 1 which is a pointer display device according to the present embodiment.

[0030] The electronic timepiece 1 includes a housing 2 , a display panel 3 , hands 30 , a digital display screen 41 , and the like.

[0031] The housing 2 internally stores various structures such as a microcomputer and a battery involved in the operation of the electronic watch 1. The housing 2 is open at the top and bottom, and the display panel 3 is located on the upper surface (the side where the user visually confirms the display). Marks (time characters) and scales indicating the time are arranged on the periphery of the display panel 3. The pointer 30 can rotate above the display panel 3 in a plane parallel to the display panel 3. Here, three pointers, namely the hour hand, the minute hand and the second hand, are illustrated as the pointers 30, but the number of the pointers 30 is not limited to three. In addition, not all the pointers 30 may rotate with a common rotation axis near the center. The top of the display panel 3 and the pointer 30 is covered by a transparent windshield glass which is omitted from the illustration.

[0032] The digital display screen 41 is located at the 6 o'clock position of the display panel 3 and performs digital display. The digital display screen 41 mainly includes a segment display area 411 capable of limited display of time and date, and a dot matrix display area 412 for displaying text and logos indicating the day of the week, etc. in dots. In addition, the digital display screen 41 may be entirely dot matrix display or may have segments that light up in the form of dedicated logos, and its structure is not particularly limited.

[0033] Figure 2 : is a block diagram showing the functional structure of the electronic timepiece 1 .

[0034] The electronic watch 1 is, for example, a wristwatch and includes a CPU 10 (Central Processing Unit) (control unit, computer), a storage unit 20, a pointer 30, a gear train mechanism 31, a stepping motor 32, a drive unit 33 (first processing unit), a digital display unit 40 (display unit), a notification operation unit 45, an operation receiving unit 50, a communication unit 60, an antenna AN, an oscillating unit 70, a timing circuit 80, and the like.

[0035] The CPU 10 is a processor that performs calculation processing and generally controls the operation of the electronic timepiece 1. The CPU 10 may not be a single processor, but may include a plurality of processors that operate in parallel or independently.

[0036] The storage unit 20 includes a volatile memory, namely a RAM (Random Access Memory) and a non-volatile memory. The volatile memory provides a storage space for the CPU 10 to perform operations and stores temporary data. The non-volatile memory is, for example, a flash memory, and stores a program 21 and setting data. The setting data includes notification category information 22 described later.

[0037] Each time a pulse-shaped electrical signal is input to the stepping motor 32, the rotor rotates relative to the stator at a preset angle. The gear train mechanism 31 is a gear train that rotates according to the rotation of the stepping motor 32, converts the rotation angle of the rotor of the stepping motor 32 into the rotation angle of the pointer 30 and transmits it to the rotation axis of the pointer 30. The pointer 30 rotates via the gear train mechanism 31 according to the rotation of the stepping motor 32. The electronic watch 1 may also have a stepping motor 32 and a gear train mechanism 31 for each of the multiple pointers 30. In addition, it may also have multiple pointers 30 that rotate in conjunction with a common stepping motor 32 via a gear train mechanism 31 that branches off in the middle.

[0038] The driving unit 33 performs processing of outputting the above-mentioned pulse-shaped electrical signal to the stepping motor 32 as a driving signal for causing the stepping motor 32 (i.e., the pointer 30) to rotate according to the control signal input from the CPU 10, so as to cause the pointer 30 to rotate. The driving unit 33 has a timing circuit 331. The timing circuit 331 counts the time interval (pulse interval) from the output of the driving signal to the time when the next driving signal can be output. That is, during the period when the timing circuit 331 counts the pulse interval, even if the action reservation of the pointer 30 is made according to the control signal from the CPU 10, the driving signal is not output. In addition, the next action reservation is made before the timing circuit 331 finishes counting the pulse interval, thereby continuously outputting the driving pulse at the pulse interval, and performing a fast-forward action (specific action) in which the pointer 30 rotates in a fast-forward manner. The driving unit 33 can be capable of driving multiple stepping motors 32 at the same time, or can be adjusted to stagger the output timing of each driving signal in a manner of exclusively outputting the driving signal. The operation reservation data is written into the register of the driving unit 33 , and is deleted when the driving signal is output from the driving unit 33 .

[0039] The digital display unit 40 has the digital display screen 41, and simple digital display is performed on the digital display screen 41 under the control of the CPU 10. The digital display screen 41 is, for example, a liquid crystal display screen, but is not limited thereto. In addition, the digital display screen 41 may also be, for example, an organic EL (Electro-Luminescent) display screen. As described above, the digital display screen 41 includes a segment display area 411 and a dot matrix display area 412.

[0040] The notification operation unit 45 performs a notification operation to inform the user of the electronic watch 1 under the control of the CPU 10. The notification operation is not particularly limited, and may be, for example, the output of a sound such as a buzzer, or the generation of vibration, etc. As the mechanism related to the sound output and the generation of vibration, a conventionally known mechanism, such as an oscillation circuit, a motor with a counterweight, etc., may be used.

[0041] The operation receiving unit 50 receives an input operation from the outside by a user or the like, and outputs an input signal based on the input operation to the CPU 10. The operation receiving unit 50 includes, for example, one or more button switches and a crown. In this case, the received input operation may include pressing the button switch, pulling out, pressing back, and rotating the crown, etc.

[0042] The communication unit 60 controls the wireless communication with the external device via the antenna AN according to the communication standard. The communication standard that the communication unit 60 can control is not particularly limited, and it is, for example, Bluetooth (registered trademark) and the like. In particular, the communication unit 60 can communicate under the low-power standard (denoted as BLE) within Bluetooth. Alternatively, the communication standard may also include various standards related to wireless LAN (Local Area Network). The communication unit 60 performs communication processing (certain processing) according to the second clock signal as described later. The communication unit 60 corresponds to the second processing unit of the present invention. The communication unit 60 has a temporary storage unit 61. The temporary storage unit 61 is a register, which can temporarily store (buffer, etc.) sent and received data.

[0043] The oscillating unit 70 oscillates a signal of a certain frequency and outputs the signal of the oscillating frequency as a clock signal. The oscillating unit 70 has a first circuit 71 and a second circuit 72 that output signals of different frequencies. The first circuit 71 oscillates and outputs a signal of, for example, 32 to 64 kHz as a first clock signal (first frequency signal). The second circuit 72 uses an oscillation element different from the first circuit 71 to oscillate and output a second clock signal (second frequency signal) of 2 MHz having a frequency higher than the first clock signal. The oscillating unit 70 selectively switches any one of these first clock signals and the second clock signal and outputs it to the CPU 10. The CPU 10 outputs one of the input first clock signal and the second clock signal to the driving unit 33 and the communication unit 60. In addition, the oscillating unit 70 may also have a frequency dividing circuit that can convert the oscillation frequency into other frequencies and output them.

[0044] The timing circuit 80 counts the passage of time according to the signal input from the oscillating unit 70 via the CPU 10 and holds the date and time. The timing circuit 80 may be a specific hardware circuit or a circuit in which the CPU 10 counts and holds the date and time on the RAM of the storage unit 20. In addition, the date and time held by the timing circuit 80 may be appropriately corrected based on the date and time data obtained from the outside by the communication unit 60. The held date and time may be the date and time (local time) of the time zone to which the electronic watch 1 currently resides, or may be fixed to the date and time of a specific time zone. In addition, in an electronic watch 1 that can simultaneously display the time of multiple time zones (for example, the time of the current location: basic time, and the time of other locations set by the user, etc.: dual time), the time of the multiple time zones may also be counted and held in parallel. The time zone information may be stored and held separately in the storage unit 20. This information may be used to display the time zone (such as the city name representing the time zone), and in addition, when the date and time of a specific time zone is held, it may also be used to convert the local time to the time zone to which the current location of the electronic watch 1 or the location of the display object of the date and time belongs.

[0045] In addition, the structure that performs control operations of the CPU 10, the drive unit 33, the communication unit 60, etc. may actually perform operations using a hardware processor that is partially or entirely shared by them, or may perform operations using independent hardware processors (microcomputers, etc.).

[0046] Next, the operation control of the pointer 30 will be described.

[0047] The rotation of the pointer 30 is triggered by the output of a control signal (action reservation) from the CPU 10 to the drive unit 33 (interrupt processing) to move the pointer 30 in any rotation direction. When the control signal is input to the drive unit 33, the drive signal is output to the stepping motor 32 during the period when the action is not prohibited by the counting of the timing circuit 331 as described above, thereby rotating the rotor of the stepping motor 32. According to the rotation of the rotor, the pointer 30 rotates via the gear train mechanism 31.

[0048] The CPU 10 stores the position information of each pointer 30 in its register, and updates the position information every time a control signal is output to the drive unit 33. When the pointer 30 is made to perform a multi-step fast forward action, the CPU 10 stores the fast forward target position information in the register when the fast forward target position is determined, and sequentially outputs control signals to the drive unit 33 at the above-mentioned pulse interval until the current position of the pointer 30 is equal to the fast forward target position or until the end command of the fast forward is obtained. The maximum fast forward speed is mechanically determined by the size of the torque, inertia, etc. of the rotor, for example, 16Hz to 120Hz. Here, as an example, the maximum fast forward speed is set to 64Hz. The fast forward speed may also be different in the case of clockwise fast forward and counterclockwise fast forward. In addition, the fast forward speed may also be variable. For example, the timing circuit 331 of the drive unit 33 counts the 32kHz signal output by the first circuit 71 as the first clock signal for 1 / 64 seconds (500 times) every time a drive signal is output, thereby determining the fast forward speed to be 64Hz.

[0049] The fast forward action is not particularly limited, and examples thereof include a change in the local time (time zone) of the displayed time (including the switching of the base time and the dual time, etc.), a change in the time associated with the start and end of daylight saving time, and the retreat and restoration of the pointer 30 from the digital display screen 41. In addition, when the date is displayed by a rotating disk, etc., the change in the date can also be included in the fast forward action.

[0050] In addition, the pointer 30 is not limited to the fast forward action of designating the movement destination of the pointer 30 and continuously moving the pointer 30 at a predetermined movement speed (time interval) until the pointer 30 reaches the movement destination position as described above. The pointer 30 movement related to the basic function, that is, the movement of rotating the pointer 30 at a predetermined time interval (not particularly limited, for example, the second hand is rotated at 1 second intervals, the minute hand is rotated at 10 second intervals, and the hour hand is rotated at 2 minute intervals) in the time display, and the entire pointer movement including the movement with a shorter time interval than the basic movement may be included in the specific action as an action with a large processing load based on the fast forward action. The specific action may include, for example, an action of displaying a measurement value corresponding to a measurement action of a sensor or the like in real time (for example, at least 1 Hz), an action of displaying the count time to a value less than 1 second in the stopwatch function, etc.

[0051] Next, the communication operation and event occurrence notification operation are described.

[0052] The electronic watch 1 is connected to an external device such as a smartphone via BLE. The communication connection can also be always maintained (in BLE, in the absence of physical data to be sent or received, control data is periodically exchanged at a wider interval than when physical data is sent or received), but it can be disconnected, for example, when the communication process is intentionally stopped in the electronic watch 1 or the external device by user operation, when the communication process is stopped due to insufficient battery, when the electronic watch 1 and the external device are not within the distance range where communication is possible (link loss), etc. The received data is temporarily stored in the temporary storage unit 61, and then forwarded to the storage unit 20 in sequence.

[0053] The electronic watch 1 can send information related to the occurrence of an event in the external device (event occurrence information) to the electronic watch 1 according to the setting in the external device. In the electronic watch 1, the occurrence of the event can be notified according to the received event occurrence information. The setting in the external device is not particularly limited, and can be performed by a dedicated application (application) corresponding to the notification action of the event occurrence in the electronic watch 1. When the setting information is updated by the application, the setting information is sent to the electronic watch 1 during the period when the communication connection with the electronic watch 1 is established. Based on the setting information, the notification category information 22 is updated.

[0054] The categories of events that send event occurrence information to the electronic watch 1 include, for example, incoming phone calls, received emails, received messages from SNS (Social Network Service), and notifications of registered schedules. These events are predetermined and stored in the category information 22. In the external device, it is also possible to set whether to make notifications related to the occurrence of the event according to the category of the event. In the electronic watch 1, when these event occurrence information are received, the category of the event is determined, and a notification action (predetermined notification action) is performed to display the category of the determined event through the digital display unit 40. The category of the event is determined, for example, by the content of the header of the received data. For event categories that cannot be determined based on the content of the header, they can be set to other categories. In the case where there is an event category that can be determined or inferred based on content other than the header such as the text, the relevant part of the received data such as the text can also be parsed.

[0055] Figure 3 1 is a diagram showing an example of a notification pattern displayed by the digital display unit 40 .

[0056] In the dot matrix display area 412 of the digital display unit 40, an identifier (icon, etc.) of a notification mode corresponding to the event category can be displayed. Figure 3 As shown in (a), an icon representing a telephone is displayed. This display may also be repeated with black and white inversion at predetermined time intervals, such as two black and white inverted images in which the white part and the black part are inverted with each other as shown by arrows (the same applies to the following icons).

[0057] When an e-mail is received, the Figure 3 When receiving a message from SNS, the Figure 3 When receiving a schedule notification, the Figure 3 In addition, if a notification that does not match the above categories is received, the display Figure 3 The image data of these icons are also included in the notification category information 22, and may be stored separately in correspondence with the event category.

[0058] Next, operation control related to switching of clock signals will be described.

[0059] In the electronic watch 1 of the present embodiment, the processing load of the operations of the CPU 10, the drive unit 33, the digital display unit 40, and the operation receiving unit 50 is small, and the operations are fully performed according to the first clock signal output by the first circuit 71. On the other hand, in the operation of the electronic watch 1, the communication processing of the communication unit 60 is performed according to the second clock signal output by the second circuit 72 in order to process data in real time according to the communication speed. Therefore, during the period when the communication unit 60 performs the communication processing (depending on the presence or absence of the communication processing), the clock signal output by the oscillation unit 70 is switched from the first clock signal to the second clock signal by the control of the CPU 10. Accompanying this, each unit that usually operates with the first clock signal is also switched to an operation based on the second clock signal. In the process of generating and outputting the second clock signal, compared with the process of generating and outputting the first clock signal, the power consumption temporarily increases and the heat generation also increases, so when the communication processing is completed, the output of the oscillation unit 70 returns from the second clock signal to the first clock signal through the CPU 10.

[0060] The communication processing mentioned here includes the processing involved in obtaining the above-mentioned event occurrence information and determining the event category. While maintaining the communication connection, the event occurrence information is received one by one at any time. On the other hand, when the communication connection is temporarily disconnected as in the above-mentioned examples in the state where the setting for notification of event occurrence is executed, the data of the event occurrence information of the sending object is accumulated in the external device, and the data is sent after the communication connection is restarted (transferred from the state where the communication is disconnected to the state where the communication connection is established). In particular, in a smartphone that uses Apple's iOS as an operating system (OS), since unified transmission control of data related to multiple events (applications) is not performed, the data of all the event occurrence information accumulated at one time is received by the communication unit 60, and the amount of received data at one time easily exceeds the capacity of the temporary storage unit 61 and overflows. The received data stored in the temporary storage unit 61 is quickly processed by the second clock signal, and the necessary data is moved to the storage unit 20, thereby stably and continuously receiving the data of the event occurrence information.

[0061] The fast forward operation of the pointer 30 has a large load in the processing that can be operated with the first clock signal. Therefore, in order to perform the operation control corresponding to the change of the frequency signal for the fast forward operation of the pointer 30, the structure is complicated, and the further increase in the processing load (increase in power consumption) of the electronic watch 1 cannot be ignored. In addition, in the driving unit 33, there is a case where the update of data related to the fast forward operation other than the first clock signal is uniformly prohibited.

[0062] Therefore, in the electronic watch 1, the fast forward action (specific action) of the pointer 30 is prohibited during the communication process. The pointer 30 in the middle of the fast forward action temporarily stops at its intermediate position (the fast forward action is temporarily interrupted), and after the communication process is completed, the fast forward action is restarted and moved to the target position. When a command to fast forward the pointer 30 is obtained during the execution of the communication process, the execution of the fast forward action is suspended and waited, and the fast forward action is started and executed after the communication process is completed.

[0063] The end timing of the communication processing can also be obtained in real time. Alternatively, the prohibition time (maximum value) of the fast-forward action until the fast-forward action is confirmed to be started again when the fast-forward action is temporarily interrupted can also be determined based on the communication volume predicted according to conditions (for example, the above-mentioned OS, the connection status of the communication, etc.). The prediction of the communication volume can not only consider whether the communication connection is restarted, but also consider the length of the communication disconnection time, etc. In addition, the communication volume can also be predicted more dynamically based on past performance, such as the number of events in the same time period of the previous day or a recent period. Here, when the predicted communication volume (not limited to event occurrence information, but also including control data and other communication data involved in the establishment of the communication connection) is above the pre-set benchmark, the prohibition time is set to be longer (the first prohibition time, for example, 12 seconds), and when the communication volume is predicted to be less, the prohibition time is set to be shorter than the above-mentioned first prohibition time (the second prohibition time, for example, 2 seconds), but it is not limited to this. In the case where the communication volume can be predicted more finely and quantitatively, the first prohibition time can be changed dynamically, and the prohibition time of more than three stages can also be determined.

[0064] In addition, when the predicted communication volume (event occurrence information) is large (satisfying the above conditions), even if all event occurrences are notified, there may be duplications or the time has passed since the event occurred and the event is no longer meaningful to the user, which may not necessarily improve the convenience of the user. Therefore, in the electronic watch 1, the initial event occurrence information among the multiple event occurrence information received in the order of event occurrence can also be ignored, and after a reference time (here, for example, 10 seconds, the first prohibited time is longer than the reference time) has passed since the start of reception, the last (most recent) event occurrence information is obtained from the middle or only obtained, and stored in the storage unit 20, and a notification action related to a part of the event category determined based on the stored event occurrence information is performed.

[0065] Figure 4 This is a flowchart showing a control procedure performed by the CPU 10 in the event occurrence information acquisition control process executed in the electronic timepiece 1 according to the present embodiment.

[0066] The event occurrence information acquisition control processing is started in the following manner, that is, when the communication unit 60 operates to obtain a predetermined category of information between the external device and the communication unit 60 (which can also be limited to the case of including the above-mentioned event occurrence information), when the communication unit 60 actually receives data from the external device, for example, at each communication timing during the period when the communication connection is established, in particular, when a request for sending physical data is sent from the communication unit 60 to the external device, or when a communication connection request is received by receiving an advertisement of the local machine, the communication unit 60 notifies such information.

[0067] When the event occurrence information acquisition control process starts, the CPU 10 determines whether the pointer 30 is in the middle of fast forwarding (step S101). If it is determined that the pointer 30 is in the middle of fast forwarding ("Yes" in step S101), the CPU 10 stops outputting the control signal to the drive unit 33 and stops the fast forwarding (step S102). Then, the CPU 10 transfers the process to step S103. If it is determined that the pointer 30 is not in the middle of fast forwarding ("No" in step S101), the CPU 10 transfers the process to step S103.

[0068] When the processing of steps S101 and S102 is transferred to the processing of step S103, CPU 10 causes the oscillation unit 70 to activate the second circuit 72, outputs the second clock signal from the second circuit 72, and outputs the input second clock signal to the drive unit 33 and the communication unit 60, etc. (step S103).

[0069] The CPU 10 determines whether the OS type of the external device that is the source of the received data is iOS (step S104). The OS information may be separately stored in advance in correspondence with BLE pairing information (bonding information) and the like, and obtained by referring to the stored information.

[0070] When it is determined that the type of OS of the external device is iOS ("Yes" in step S104), the CPU 10 determines whether the current communication is performed by recovery from link loss or with activation of the communication unit 60 (step S105). When it is determined that the communication is performed by recovery from link loss or with activation of the communication unit 60 ("Yes" in step S105), the CPU 10 sets the prohibition time from the start of acquisition of received data in the processing of the next step S107 (or from the current time or from the start of the event generation information acquisition control processing, whichever is almost irrelevant) to the fast forwarding action of the pointer 30 to 12 seconds (step S106). The CPU 10 sequentially acquires the received data from the temporary storage unit 61 of the communication unit 60 and stores it in the storage unit 20. At this time, the CPU 10 may delete the data for 10 seconds from the start of reception without retaining it (step S107). Alternatively, the CPU 10 may sequentially overwrite and update the event generation information in the storage unit 20 in such a manner that only the latest event generation information is retained. Then, the processing of the CPU 10 proceeds to step S121 .

[0071] When it is determined in the determination process of step S104 that the OS of the external device that is the transmission source of the received data is not iOS (No in step S104 ), the process of the CPU 10 shifts to step S111 .

[0072] In the determination process of step S105 , when it is determined that the current communication is not being performed by recovery from link loss and is not being performed with activation of the communication unit 60 (No in step S105 ), the CPU 10 proceeds to step S111 .

[0073] When the judgment process of step S104 or step S105 branches to "No" and transfers to the process of step S111, the CPU 10 sets the prohibition time from the acquisition of the received data in the next step S112 (or from the current time or from the start of the event information acquisition control process) to the fast forward action of the pointer 30 to 2 seconds (step S111). The CPU 10 obtains the received data from the temporary storage unit 61 of the communication unit 60 and stores it in the storage unit 20 (step S112). Then, the process of the CPU 10 transfers to step S121.

[0074] When the process is transferred from the process of step S107 or the process of step S112 to the process of step S121, the CPU 10 determines whether a new fast-forward action command has been obtained (step S121). In the case where it is determined that a new fast-forward action command has been obtained ("Yes" in step S121), the CPU 10 causes the notification action unit 45 to perform a sound (buzzer sound) notification action indicating that the command has been obtained, and further, performs a standby setting for the fast-forward action, prohibiting fast-forwarding until the time set in steps S106 and S111 until the fast-forward action can be performed has passed (step S122). At this time, when the prohibited fast-forward setting (fast-forward target position and fast-forward direction) is updated, the CPU 10 can delete the interrupted fast-forward setting. Then, the process of the CPU 10 is transferred to step S123. In the case where it is determined that a new fast-forward action command has not been obtained in the determination process of step S121 ("No" in step S121), the process of the CPU 10 is transferred to step S123.

[0075] When the process is transferred from step S121 or step S122 to step S123, the CPU 10 determines the category of the received content (the category of the event involved in the event occurrence information) from the received data obtained based on the notification category information 22 (step S123). The CPU 10 obtains the image data of the icon corresponding to the determined content category (event category) from the notification category information 22, and displays the icon corresponding to the image data in the dot matrix display area 412 of the digital display screen 41 through the digital display unit 40 (step S124).

[0076] CPU10 determines whether the reception from the external device is finished (step S125). In the case where it is determined that the reception from the external device is not finished ("No" in step S125), the processing of CPU10 returns to step S121. In the case where it is determined that the reception from the external device is finished ("Yes" in step S125), CPU10 controls the oscillation unit 70 so that the output of the second clock signal from the second circuit 72 returns to the output of the first clock signal of the first circuit 71, and outputs the first clock signal output from the oscillation unit 70 to the drive unit 33 and the communication unit 60 (for executing processing in a standby state without communication, etc.) as needed (step S126). In addition, before the prohibition time determined above, CPU10 may not restore the clock signal output mechanically to the first clock signal. In addition, in the case where the reception is not finished even after the prohibition time has passed, the prohibition time may be extended.

[0077] The CPU 10 determines whether a command to delete the icon displayed in the dot matrix display area 412 is obtained by the operation receiving unit 50, or whether a specified time has passed since the icon was displayed (step S127). When it is determined that a command to delete the icon is obtained, or a specified time has passed since the icon was displayed ("Yes" in step S127), the CPU 10 deletes the icon display in the dot matrix display area 412 through the digital display unit 40 (step S128). The CPU 10 ends the event occurrence information acquisition control processing. When it is determined that a command to delete the icon is not obtained and a specified time has not passed since the icon was displayed ("No" in step S127), the CPU 10 repeats the processing of step S127.

[0078] The processing of step S103, the determination processing of step S125, and the processing of step S126 constitute the frequency control step (the frequency control unit of program 21) in the pointer motion control method of this embodiment. In addition, the processing of step S102, the determination processing of step S121, and the processing of step S122 constitute the specific action prohibition step (the specific action prohibition unit of program 21) in the pointer motion control method of this embodiment.

[0079] In addition, when new event occurrence information is received after the processing of step S126 is completed and before the event occurrence information acquisition control processing is completed, new event occurrence information acquisition control processing can be started in parallel, and the previous event occurrence information acquisition control processing can be terminated by displaying the processing of step S124 in the new processing as the processing of step S128 in the previously executed event occurrence information acquisition control processing.

[0080] As described above, the pointer display control device of the present embodiment includes the CPU 10. The CPU 10 outputs the first clock signal and the second clock signal to the driving unit 33 as the first processing unit that can execute the processing for moving the pointer 30 according to the first clock signal by switching the output of the first clock signal and the second clock signal of the oscillating unit 70 having a higher frequency than the first clock signal, controls the output of the second clock signal to the communication unit 60 as the second processing unit that executes a certain processing predetermined according to the second clock signal, such as communication processing, and controls the switching of the clock signal output by the oscillating unit 70 according to whether the certain processing is executed (in the case of switching the clock signal output by the oscillating unit 70). Figure 4 In step S101 of the embodiment, "Yes" in step S102, step S125, "Yes" in step S126), during the period in which the second processing unit performs the above-mentioned processing (steps S107, S112, S121 to S124, and "No" in S125), the drive unit 33 is prohibited from performing a specific action on the pointer 30 ( Figure 4 "Yes" in step S101, steps S102, S122).

[0081] In this way, the high-frequency second clock signal is output only when processing according to the high-frequency frequency signal is required, thereby increasing the processing load and power consumption. On the other hand, during the period of outputting the second clock signal, specific actions of the pointer 30, which do not necessarily require high real-time performance, are prohibited. As a result, the CPU 10 can suppress the increase in power consumption of the electronic watch 1 (and thus the increase in product size) and improve the desired processing capacity.

[0082] In addition, when the CPU 10 causes the pointer 30 to perform a specific operation through the driving unit 33, the second processing unit starts the above-mentioned processing ( Figure 4 In step S101 of the embodiment of the present invention, the specific action of the pointer 30 is temporarily interrupted (step S102). That is, not only does the specific action not start in the middle of a certain process according to the high-frequency second clock signal, but the specific action that has already started is also interrupted in the middle, thereby enabling the processing of the second processing unit to be executed quickly and without delay. In the electronic watch 1 where it is generally difficult to imagine that the above-mentioned certain process based on the second clock signal is continuously performed for a long time, it is possible to suppress the increase in power consumption and product size, and to easily and more smoothly execute the high-priority process.

[0083] In addition, the specific action is a pointer action that generates a processing load higher than the processing load in the action involved in the basic function (i.e., the time display action here) of the pointer display device (for example, the electronic watch 1 here) controlled by the CPU 10. In a display that requires the pointer 30 to move more frequently than the time display, the processing load involved in the pointer action becomes large even if it is not a fast-forward action. By including such a pointer action with a large processing load in the specific action and prohibiting the specific action during the execution of the above-mentioned certain process, it is possible to avoid excessive power consumption at one time, and it is possible to appropriately improve the processing capacity of a certain process (communication process, etc.) with a high load that requires an action under the second clock signal.

[0084] In addition, the above-mentioned specific action is a fast-forward action of the pointer 30. The processing load of the fast-forward action is large, so when the action is performed under the second clock signal, which originally increases power consumption, the above-mentioned certain processing that requires the action under the second clock signal, the basic control processing that needs to be continued regardless of the frequency of the clock signal, etc., is limited to prohibiting the fast-forward action, so that the processing load can be suppressed from becoming too large, and the processing capacity of the necessary processing can be improved.

[0085] In addition, when the processing involved in the fast-forward action, especially the writing action to the register, is based on the action at the first clock signal frequency, by prohibiting the action at the second clock signal, the enlargement of the structure of the driving unit 33 and the complication of the processing can be suppressed, and the processing capability of the above-mentioned processing at the second clock signal can be easily improved.

[0086] Furthermore, the electronic watch 1 as a pointer display device has a communication unit 60 for communicating with an external device. The above-mentioned certain processing according to the high-frequency second clock signal includes the communication processing with the external device performed by the communication unit 60. In the communication processing of sending and receiving data with a specific device, the communication time of the external device is also affected by the data transmission interval, so by increasing the frequency of the frequency signal, smooth data transmission and reception can be performed.

[0087] In addition, the electronic watch 1 as a pointer display device has a storage unit 20 for storing data. The communication unit 60 has a temporary storage unit 61 for temporarily storing received data. When the conditions related to the predicted amount of received data from the external device are met (both "Yes" in step S104 and step S105), the CPU 10 as a control unit obtains the received data after the reference time has passed since the start of data reception from the temporary storage unit 61 and stores it in the storage unit 20 (step S107). That is, in the case of predicting the reception of a large amount of data, the original received data can also be directly discarded without obtaining it. In the data displayed in the electronic watch 1, in most cases, the urgency and substitutability of the content that cannot be directly confirmed in the electronic watch 1 are required, and the value of re-obtaining the old information after the time has passed and using it is relatively low compared to the new information. In this way, by discarding the old information and obtaining only the new information, the processing in the electronic watch 1 can be reduced and the convenience of the user can be improved. In addition, when the communication unit 60 communicates via Bluetooth, if the received data stored in the temporary storage unit 61 cannot be completely processed and an overflow occurs, the communication connection itself is disconnected, and the data of the receiving object cannot be properly obtained and the communication connection cannot be reconnected. Therefore, in the electronic watch 1, such a failure can be avoided and the necessary information can be obtained stably.

[0088] In addition, when the above-mentioned conditions related to the amount of received data are satisfied (both "Yes" in steps S104 and S105), the CPU 10 determines a reference time from the start of data reception, for example, a first prohibition time longer than 10 seconds, for example, 12 seconds, as a period for prohibiting the fast-forwarding of the pointer 30 (step S106), and when the above-mentioned conditions are not satisfied, a second prohibition time shorter than the first prohibition time, for example, 2 seconds, is determined as a period for prohibiting the fast-forwarding of the pointer 30 (step S111). When performing a communication operation, especially receiving event occurrence information, the prohibition time of the fast-forwarding of the pointer 30 is set in advance, thereby reducing processing and performing communication processing more smoothly.

[0089] In addition, the above-mentioned conditions may also include reception when the communication with the external device is disconnected and the communication connection is established (step S105). Since it is difficult to obtain the actual amount of received data when the reception from the external device starts, the electronic watch 1 includes a condition that indirectly estimates that the amount of received data has increased, thereby reducing the processing load and selectively obtaining information with high necessity.

[0090] In addition, the above-mentioned conditions may also include the type of the operating system of the external device (step S104). When receiving information related to a plurality of applications in the external device from the external device, the processing load of the electronic watch 1 when receiving data may change depending on whether the OS of the external device uniformly controls the output of the applications. Therefore, by also using the OS information as an element related to the determination of whether to selectively obtain the received data, the processing load can be reduced in the electronic watch 1, and the information with high necessity can be selectively obtained.

[0091] In addition, the CPU 10 as the control unit receives the occurrence information of a predetermined event in the external device through the communication unit 60. When the occurrence information of the event is received (step S123), a control for executing a predetermined notification action is performed. In this embodiment, a control for executing the display of the logo (icon) of the digital display unit 40 is performed (step S124). The notification action of the occurrence information of the event in the electronic watch 1 is effective when the user cannot hold the external device or puts the external device at hand, and the rapidity of such information is important. By quickly performing the reception process of such information according to the second clock signal and suppressing power consumption, the convenience of the user of the electronic watch 1 can be improved.

[0092] Then, the CPU 10 as the control unit determines the type of event involved in the received occurrence information, and performs a notification operation by displaying an icon indicating the determined type through the digital display unit 40 (step S124). Performing a notification operation related to the occurrence of an event by displaying it on the digital display screen 41 can easily improve the user's ability to distinguish the event type compared to other notification operations such as sound mode and vibration mode.

[0093] In addition, when the CPU 10 as the control unit continuously receives the occurrence information of multiple categories of events from the external device through the communication unit 60, it displays a part of the multiple categories through the digital display unit 40. As described above, the promptness of the notification action of the event occurrence is important. Even if all the old occurrence events are displayed in order, the user's convenience will be reduced because the display that is less useful to the user is mixed, the display time becomes longer, or the same display is repeated. Therefore, by selecting only the display related to a part of the categories, the notification content to be conveyed to the user is narrowed, and the user's convenience can be improved in the electronic watch 1.

[0094] In addition, some of the above categories may be categories related to events whose occurrence information has been received recently. That is, by displaying only the categories of the latest events, it is possible to emphasize only the rapidity of the report and reduce the judgment related to the user's information acquisition.

[0095] In addition, the electronic watch 1 as a pointer display device of the present embodiment comprises: the above-mentioned CPU 10, the pointer 30; the driving unit 30 as the first processing unit capable of executing the processing for moving the pointer 30 according to the first clock signal; the communication unit 60 as the second communication unit that performs a predetermined processing such as communication processing according to the second clock signal; and the oscillating unit 70 that switches and outputs the first clock signal and the second clock signal. According to such an electronic watch 1, the second clock signal is output only when the processing according to the high-frequency frequency signal is required, so that the increase in power consumption can be suppressed when it is not necessary. In addition, during the period of outputting the second clock signal, the specific action of the pointer 30, which does not necessarily have a high real-time requirement but has a slightly large action load, is prohibited, thereby suppressing the increase in power consumption and the generation of excessive load in the electronic watch 1, while improving the processing capacity.

[0096] In addition, the pointer display action control method of the present embodiment includes: a first output step, outputting the first clock signal or the second clock signal to the drive unit 33 through the oscillator unit 70; a second output step (the first output step and the second output step are both steps S103 and S126), controlling whether the second clock signal is output to the communication unit 60 as the second processing unit performing a predetermined processing (for example, communication processing); a frequency control step (steps S103, "Yes" in S125, S126), controlling the above-mentioned switching of the oscillator unit 70 that switches the output of the first clock signal and the second clock signal according to the presence or absence of the communication processing of the communication unit 60 as the above-mentioned processing; and a specific action prohibition step (steps S102, "Yes" in step S121, S122), prohibiting the fast-forward action of the specific action of the pointer 30 performed by the drive unit 33 during the period when the communication unit 60 as the second processing unit performs the above-mentioned processing.

[0097] In this way, the second clock signal is output only when processing according to the high-frequency frequency signal is required. During this period, by prohibiting the fast-forward movement of the pointer 30, the pointer movement can be controlled to suppress the increase in power consumption of the electronic watch 1 and improve the desired processing capacity.

[0098] In addition, the program 21 of the present embodiment causes the computer (CPU 10) of the electronic watch 1 to function as the following units: a first output unit that outputs the first clock signal or the second clock signal to the drive unit 33 through the oscillating unit 70; a second output unit (both the first output unit and the second output unit are steps S103 and S126) that controls whether the second clock signal is output to the communication unit 60, which is a second processing unit that performs a predetermined processing (for example, communication processing); a frequency control unit (steps S103 and S125, "Yes", S126) that controls the above-mentioned switching of the oscillating unit 70 that switches the output of the first clock signal and the second clock signal according to the presence or absence of the above-mentioned processing (communication processing of the communication unit 60); and a fast-forward prohibition unit (steps S102 and S121, "Yes", S122) that prohibits the fast-forward action, which is a specific action of the pointer 30, performed by the drive unit 33 during the period when the communication unit 60, which is the second processing unit, performs processing under the second clock signal.

[0099] By installing such a program 21 in a pointer display control device (pointer display device) that can selectively output two clock signals to control the pointer movement, it is possible to set an additional structure without making the electronic watch 1 larger or more complicated, thereby easily suppressing the increase in power consumption and improving the control of the pointer movement of the desired processing capacity.

[0100] In addition, the present invention is not limited to the above-mentioned embodiment, and various modifications can be made.

[0101] For example, in the above embodiment, the time from the start of the above-mentioned certain processing to the timing at which the pointer can be fast-forwarded is set according to the condition, but the fast-forwarding of the pointer is determined only by the presence or absence of communication processing, and the presence or absence of read-after-discarding of received data can also be determined according to the above-mentioned condition. Alternatively, if only the most recent event occurrence information is always obtained, the CPU 10 may not judge the condition, and overwrite and update the data of the event occurrence information each time an event occurs and maintain it.

[0102] In addition, in the above-mentioned embodiment, the execution of the communication process (certain process) is always prioritized over the fast forward action (specific action), but the present invention is not limited thereto. As long as the fast forward action is not performed simultaneously with the communication process, for example, when the remaining time of the fast forward action is short, the transmission and reception of data (other than control data, etc.) based on the communication process may be started after the fast forward action is completed.

[0103] In addition, in the above-mentioned embodiment, when a start command of fast forward (specific action) is obtained during the execution of communication processing (certain processing), the notification action unit 45 is caused to perform a notification action, but the notification action may not be performed at all. For example, the notification action may be performed only when a command of fast forward action is manually obtained through the operation receiving unit 50, and the notification action may not be performed when a fast forward start command is performed in the internal processing of the CPU 10 regardless of user operation or the like because it is determined that the start timing of the fast forward action is obtained. Alternatively, the notification action may not be performed regardless of the type of the start command. In addition, the presence or absence of the notification action may also be switched by setting.

[0104] In the above embodiment, after the category of the acquired event occurrence information is determined, the icon corresponding to the content category is displayed on the digital display unit 40, but after the reception is completed, the icon corresponding to the category of the last acquired event occurrence information may be displayed.

[0105] In addition, in the above-mentioned embodiment, when receiving multiple event occurrence information, the category related to the most recent one or part of the occurrence events is selectively displayed, but it is not limited to this. Even slightly older information may be highly useful to the user depending on the category of the event, so the usefulness judgment criteria may be predetermined to determine whether display (notification) is required for each of the older events. In addition, in this case, for repeated events, they may be displayed once instead of multiple times.

[0106] In addition, in the above embodiment, the case where the content received from the external device is event occurrence information is described, but in fact, other information can also be received. In this case, there is no difference in the judgment criteria for whether the event occurrence information can be received at the same time, so the processing can be performed in the same way as the processing described in the above embodiment. Then, in Figure 4 In the determination process of step S123, when it is determined that the received content does not include event occurrence information, the CPU 10 simply omits the display of the icon on the digital display screen 41 and the processing involved in its deletion (steps S124, S127, S128).

[0107] In addition, in the above-mentioned embodiment, the case where the pointer 30 performs a rotational action around the rotation axis is described, but the electronic watch 1 may also have a pointer that moves in parallel within a certain set range. In addition, even in the case of a rotational action, it is possible not to rotate 360 ​​degrees, but to perform a reciprocating action only within a certain angle range. In addition, the pointer mentioned here includes a pointer that can perform display-related actions by a stepping motor, such as a rotating circular plate. In addition, sometimes a plurality of pointers 30 are divided into a plurality of groups according to each portion of the pointers 30 and perform different display actions respectively. At this time, it is also possible to prohibit the display action of the group of display actions with a processing load greater than the processing load of the display action involved in the basic function (i.e., the time display action in the electronic watch 1) during the above-mentioned processing.

[0108] In addition, in the above-mentioned embodiment, the case of determining and displaying the category of the event is described, but the determination of the category can also be more detailed. For example, the SNS can also be determined separately for each application. Or, on the contrary, the category of the event can be determined without determining it, and only the events that have occurred in the external device can be notified. In this case, even if the notification method is not limited to display, the user can more easily recognize that the event has occurred. In addition, the real-time notification action itself is not necessary in the present invention. For example, it can also be the reception and acquisition of log information, and then the data that is called out and displayed through the input operation accepted by the operation acceptance unit 50. In addition, the data received and notified may not be event occurrence information, but simple navigation data, etc.

[0109] In the above embodiment, the external device is described as operating in a manner that sends event information regardless of maintaining or disconnecting the communication connection, but the present invention is not limited thereto. During the period when the communication connection is disconnected through normal processing, the processing to send event information from the external device may not be performed.

[0110] In addition, in the above embodiment, communication processing is used as an example of a certain process, but it is not limited to this. A heavy load process that requires a temporary increase in frequency to process, such as real-time measurement and analysis processing using sensors, etc., can also be set as the above-mentioned certain process performed under the second clock signal.

[0111] In addition, in the above-mentioned embodiment, the case where the pointer display device is an electronic watch 1 is described, but the present invention is not limited to this. Any display device that uses a pointer for display and performs a specific action with a processing load greater than the action of the pointer 30 involved in the basic function such as the fast forward action of the pointer position can be used. In this case, even in the display action of the display device, the processing load of the pointer action becomes large, so it is not limited to the fast forward action, etc., and the pointer action can be prohibited as a specific action as a whole during the execution of a certain process (communication process).

[0112] In addition, in the above description, as a computer-readable medium storing the program 21 including the pointer motion control of the present invention, the storage unit 20 composed of a non-volatile memory such as a flash memory is cited as an example for description, but it is not limited to this. As other computer-readable media, other non-volatile memories such as HDD (Hard Disk Drive), MRAM, and removable recording media such as CD-ROM and DVD disks can be applied. In addition, as a medium for providing data of the program involved in the present invention via a communication line, a carrier wave is also applicable to the present invention.

[0113] Furthermore, the specific configurations, contents of processing operations, steps, and the like shown in the above-described embodiments can be appropriately modified within the scope not departing from the gist of the present invention.
