It is a flowchart which shows an example of a power supply sequence setting process. It is a flowchart which shows an example of a power supply sequence control process.

  Hereinafter, modes for carrying out the present invention will be described.

  First, the configuration of a digital photo frame (DPF) apparatus according to the present embodiment will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration example of a digital photo frame apparatus.

  The digital photo frame apparatus 1 displays a photograph taken by a digital camera or the like, and controls power by monitoring voice input. As shown in FIG. The memory card insertion unit 20, the display unit 30, an operation switch (Switch; SW) 40, a microphone (MIC) 50, a power supply sequence memory 60, and a main body unit 70 are schematically configured. They are connected to each other via a bus.

  The power supply unit 10 converts, for example, an AC (Alternating Current) power source input via a power cord into a DC (Direct Current) power source having a predetermined voltage and supplies the converted power to the display unit 30. The power supply unit 10 may supply DC power of a predetermined voltage to the display unit 30 from various secondary batteries or dry batteries, for example.

  The memory card insertion unit 20 is for inserting an external recording medium such as a memory card, and includes a memory card slot for connecting a memory card inserted therein. Here, the memory card is composed of, for example, a flash EEPROM (Electrically Erasable and Programmable ROM) abbreviated as SSFDC (Solid-State Floppy Disk Card), and is a compressed image of a photograph (still image) taken with a digital camera or the like. Record the data.

  The display unit 30 is composed of, for example, a liquid crystal display (LCD) or the like. When the power supply from the power supply unit 10 is on, the compressed image data in the memory card inserted into the memory card insertion unit 20 is displayed. While the photo based on is displayed on the screen, the display of the photo is turned off when the power supply is off. Note that the photos displayed on the screen of the display unit 30 may be sequentially switched at predetermined intervals.

  Further, on the screen of the display unit 30, the power sequence (on / off table) stored in the power sequence memory 60 is displayed.

  The operation switch 40 is operated by the user. For example, a fast-forward search button, a play / stop button, a fast-rewind search button, a rotate button, a display button, a cross key, a display unit, etc. It consists of a touch panel displayed on 30 screens. The operation switch 40 functions as a user interface (UI) of the digital photo frame apparatus 1.

  By operating the operation switch 40, the user can correct, for example, the setting of the power supply sequence stored in the power supply sequence memory 60 in accordance with his / her life pattern.

  The microphone 50 inputs audio around the digital photo frame device 1 and outputs an audio signal to the main body unit 70.

  The power supply sequence memory 60 is composed of, for example, a flash EEPROM abbreviated as SSFDC, and stores a power supply sequence created and updated by the main body unit 70.

  FIG. 2 is a diagram illustrating an example of a power supply sequence.

  In the power supply sequence, as shown in FIG. 2, a recommended value for turning the power on or off is set for each time period (in this embodiment, “one week” in this embodiment). “Every hour”). In FIG. 2, “*” indicates that the power supply is recommended to be turned on, and “−” indicates that the power supply is recommended to be turned off.

  A main body 70 shown in FIG. 1 controls the operation of each part of the digital photo frame device 1. For example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a DRAM (Dynamic Random). Access Memory).

  The main unit 70 reads compressed image data from a memory card inserted in the memory card insertion unit 20 and records it in a built-in DRAM, and writes the image data obtained by decompressing the compressed image data to the DRAM. return. As a result, a photograph based on the image data is displayed on the screen of the display unit 30.

  The RAM of the main body 70 is provided with a time zone pointer, a time zone timer, a corrected flag, a display flag, and the like.

  The time zone pointer designates one of a plurality of time zones constituting a predetermined period (in this embodiment, “one week”), and the point value becomes 1 each time a new time zone is started. Incremented and updated.

  Specifically, the time zone pointer is set at the start (Monday 0: 0: 0) of the first time zone (Monday 0-1 o'clock) among a plurality of time zones constituting a predetermined period. The pointer initial value “0” is set, and the point value is incremented by 1 at the start of the next time zone (Monday 1 to 2 o'clock time) (Monday 1:00:00). Is updated.

  The time zone pointer is pointed at the start (Sunday 23:00:00) of the last time zone (Sunday 23-24 hour time zone) among a plurality of time zones constituting the predetermined period. The value is incremented by 1 and updated to “167”, which is the upper limit value of the pointer, and at the end (at the start of the first time zone), the pointer initial value “0” is set again.

  The time zone timer is a down counter that measures an elapsed time from the start of a predetermined time zone.

  Specifically, the time zone timer is set with a timer value corresponding to the length of the predetermined time zone (in this embodiment, “one hour”) as the timer initial value at the start of the predetermined time zone. Counts down regularly. When the timer value reaches the timer final value “0”, the timer initial value is set again in the time zone timer.

  A plurality of corrected flags are provided for each time zone (“168” in this embodiment), and are set to the ON state when the power sequence setting in the corresponding time zone is corrected by the user.

  The display flag is set to the on state when the display of the power supply sequence is started on the screen of the display unit 30.

  Further, the ROM of the main body unit 70 stores an analysis program, a determination program, a sequence program, and the like.

  The main body 70 functions as an analyzer 71, a determiner 72, and a sequencer 73 when the CPU uses the RAM as a work memory to execute an analysis program, a determination program, and a sequence program.

  The analyzer 71 analyzes (calculates) the audio signal input from the microphone 50 and outputs the analysis result to the determiner 72.

  For example, the analyzer 71 cuts out the audio signal supplied from the microphone 50 in predetermined frame units, obtains an average value or a spire value of the audio signal in predetermined frame units, or obtains a Mel frequency cepstrum coefficient ( Mel-Frequency Cepstrum Coefficient (MFCC) is extracted, or a frequency spectrum is extracted by performing Fast Fourier Transform (FFT) on an audio signal of a predetermined frame unit.

  Then, the analyzer 71 obtains an analysis result (any one or more of an average value, a spire value, a mel frequency cepstrum coefficient, and a frequency spectrum) obtained by performing one or more of the above analysis methods. The data is output to the determiner 72.

  The determinator 72 detects whether or not a person is present around based on the analysis result input from the analyzer 71. Then, the determinator 72 creates and updates the power supply sequence based on this detection history. Specifically, in the time zone in which it is detected that there is a person in the surroundings, the power sequence is set so that the photograph is displayed on the screen of the display unit 30, while in the time zone in which the photo is not detected, Set the photo to disappear.

  For example, the determinator 72 compares the average value (or spire value) input from the analyzer 71 with a predetermined threshold, and within a predetermined time zone (in this embodiment, “within 1 hour”), Count the number of average values (or spire values) that exceeded the threshold. Subsequently, the determinator 72 gives a recommended value “*” indicating that it is recommended to turn on the power if the number exceeding the predetermined threshold is equal to or greater than the predetermined upper limit value within the predetermined time period. On the other hand, when the power sequence is set, if it is less than the predetermined upper limit value, a recommended value “−” indicating that it is recommended to turn off the power is set.

  Then, the determinator 72 creates and updates the power supply sequence by sequentially setting the recommended values for a predetermined period (in this embodiment, “one week”) as one cycle.

  The sequencer 73 controls on / off of power supply from the power supply unit 10 to the display unit 30 according to a power supply sequence (display information) stored in the power supply sequence memory 60.

  Specifically, the sequence machine 73 reads the set value in the time zone corresponding to the day of the week and the time from the power sequence, and if the set value is “*”, the power supply unit 10 turns on the power supply to the display unit 30. By controlling the display unit 30 to operate the display unit 30 and display a photograph on the screen, if the set value is “−”, the power supply is controlled to be turned off to stop the operation of the display unit 30. To turn off the photo display.

  Next, the operation of the digital photo frame apparatus 1 having the above configuration will be described with reference to the drawings.

  The digital photo frame apparatus 1 periodically executes a power sequence setting process and a power sequence control process.

  FIG. 3 is a flowchart illustrating an example of the power sequence setting process.

  In the power supply sequence setting process, in the main unit 70, the analyzer 71 first analyzes the audio signal input from the microphone 50 and outputs the analysis result to the determiner 72 as shown in FIG. S1).

  Next, the main body 70 determines whether or not it is the end timing of the time zone indicated by the point value of the time zone pointer by determining whether or not the timer value of the time zone timer has become “0”. (Step S2).

  Here, if it is the end timing of the time zone indicated by the point value (step S2; Yes), the main body 70 determines whether or not the corrected flag corresponding to the time zone is on (step). S3).

  Here, if the corrected flag is off (step S3; No), in the main unit 70, the determinator 72 indicates the point value of the time zone pointer based on the analysis result input from the analyzer 71. It is determined whether or not there is a person around the digital photo frame device 1 in the time zone (step S4).

  Here, when it is determined that there is a person around the digital photo frame device 1 (step S4; Yes), the power sequence stored in the power sequence memory 60 is in the time zone indicated by the point value. A recommended value “*” indicating that it is recommended to turn on the power is set in the corresponding portion (step S5).

  On the other hand, when it is determined that there is no person around the digital photo frame device 1 (step S4; No), the power supply sequence includes a power supply corresponding to the time zone indicated by the point value. A recommended value “−” indicating that it is recommended to turn off is set (step S6).

  When it is determined in the process of step S3 that the corrected flag is on (step S3; Yes), after the process of step S5 or S6 is executed, the point value of the time zone pointer is incremented by 1 and updated. At the same time (step S7), it is determined whether or not the updated point value is larger than the pointer upper limit value “167” (step S8).

  Here, if the updated point value is larger than the pointer upper limit value (step S8; Yes), the main body unit 70 sets the pointer initial value “0” in the time zone pointer (step S9), but after the update. If the point value is less than or equal to the pointer upper limit value (step S8; No), the process of step S9 is skipped.

  And the main-body part 70 starts the measurement of the elapsed time in the time slot | zone which the point value of the updated time slot | zone pointer shows by setting a timer initial value to a time slot | zone timer and starting countdown of a timer value. (Step S10).

  If it is determined in the process of step S2 that it is not the end timing of the time zone indicated by the point value (step S2; No), whether or not the display flag is on after executing the process of step S10. Is discriminated (step S11).

  If the display flag is off (step S11; No), it is determined whether or not the display of the power sequence stored in the power sequence memory 60 is instructed by the operation of the operation switch 40 by the user. (Step S12).

  Here, when it is determined that the display of the power supply sequence is not instructed (step S12; No), the power supply sequence setting process is terminated as it is.

  On the other hand, when it is determined that the display of the power supply sequence is instructed (step S12; Yes), the power supply sequence is displayed on the screen of the display unit 30 (step S13), and the display flag is turned on. After setting (step S14), the power sequence setting process is terminated.

  When it is determined in the process of step S11 that the display flag is on (step S11; Yes), the user operates the operation switch 40 to instruct correction of the power supply sequence setting in a predetermined time zone. It is determined whether or not (step S15).

  If it is determined that the power sequence setting correction is not instructed (step S15; No), the power sequence setting process is terminated as it is.

  On the other hand, when it is determined that the correction of the power supply sequence setting is instructed (step S15; Yes), the main body unit 70 corrects the power supply sequence setting in accordance with the instruction (step S16) and the corrected time. By setting the corrected flag corresponding to the band to the ON state so that the setting of the power supply sequence in the corrected time zone is not automatically updated thereafter (step S17), the power supply sequence setting process is terminated.

  FIG. 4 is a flowchart illustrating an example of the power sequence control process.

  In this power supply sequence control process, in the main unit 70, the sequencer 73 first determines whether or not the timer value of the time zone timer matches the initial value as shown in FIG. It is determined whether or not it is the start timing of the time zone indicated by the pointer point value (step S21).

  Here, if it is not the start timing of the time zone indicated by the point value (step S21; No), the main body unit 70 ends the power supply sequence control process as it is.

  On the other hand, if it is the start timing of the time zone indicated by the point value (step S21; Yes), the main body unit 70 determines from the power supply sequence stored in the power supply sequence memory 60 in the time zone indicated by the point value. The set value is read (step S22).

  Subsequently, the sequencer 73 determines whether or not the setting value read in the process of step S22 is “*” (step S23).

  Here, if the read set value is “*” (step S23; Yes), the sequence machine 73 operates the display unit 30 by controlling the power supply from the power supply unit 10 to the display unit 30 to be on. While the photograph is displayed on the screen (step S24), if the set value is “−” (step S23; No), the operation of the display unit 30 is stopped by controlling the power supply to OFF. Then, the display of the photograph is erased (step S25), and the power supply sequence control process is terminated.

  As described above, according to the digital photo frame apparatus 1 according to the present embodiment, based on the audio signal input from the microphone 50 and the result of analyzing it by one or a plurality of methods, a predetermined period ( In the present embodiment, the time period of “one week”) is displayed on the display unit 30 to turn on the power supply and the photograph is displayed on the screen, and in which time period the power supply is turned off and the photograph display is turned off.

  As a result, the digital photo frame apparatus 1 can control the display (lighting) / non-display (non-lighting) of the photo for each time period according to the behavioral form of the person. Specifically, when there is a person around the digital photo frame device 1, the display unit 30 is operated to display a photo on the screen, while when there is no person around, the operation of the display unit 30 is stopped. You can erase the picture on the screen.

  As described above, when there is no person around, the operation of the display unit 30 is stopped to erase the picture on the screen, so that the power consumption of the digital photo frame device 1 can be reduced. The photo frame device 1 can be realized.

  In addition, since the digital photo frame apparatus 1 can create a power supply sequence by analyzing the audio signal input from the microphone 50, no lens portion such as a digital camera is provided on the surface, and no one Can be used with confidence.

  Furthermore, since the digital photo frame apparatus 1 can sequentially update the power supply sequence setting for every predetermined period (in this embodiment, “every week”), it responds to changes in the user's lifestyle pattern. You can also

  In addition, in the digital photo frame apparatus 1, the user can actively correct the setting of the power supply pattern to the detailed instructions by operating the operation switch 40. In spite of this, it is possible to make a setting such that the operation of the display unit 30 is stopped and no photo is displayed on the screen.

  Further, the digital photo frame apparatus 1 displays the power supply sequence stored in the power supply sequence memory 60 on the screen of the display unit 30 so that the user can grasp his / her own life pattern and set more. Easy power sequence can be created.
