  When not in use, home appliances such as television receivers are usually in standby mode when the main power is turned on but the main functions of the device are not operating. When the use is started (for example, when program reproduction is started), a transition is made to an activated state in which the main function operates (for example, see Patent Document 1).

  Embodiments to which the present invention is applied will be described below with reference to the drawings.

  As described above with reference to FIG. 1, the power ON button 1A of the remote commander 1 is operated in order to shift the television receiver 2 from the standby state to the activated state. The remote commander 1 that has been used is lifted.

  The present invention pays attention to the handling of the user's remote commander when the television receiver is shifted from the standby state to the activated state. As shown in the left of FIG. 2, the remote commander 11 is, for example, The movement of the remote commander 11 caused by being lifted by the user is detected, and a sensor detection signal indicating that there is a detection is transmitted to the television receiver 12.

  When the television receiver 12 is not used, the television receiver 12 is in a standby state (hereinafter referred to as a deep standby) in which power consumption can be reduced to the maximum, but when a detection signal is received from the remote commander 11, the center of FIG. As shown in FIG. 4, the system shifts to a standby state (hereinafter referred to as active standby) that can be instantly started.

  When the power ON button 11A of the remote commander 11 is operated (for example, pressed), the remote commander 11 instructs the start instruction signal (hereinafter referred to as the power ON instruction) to shift to the start state of the television receiver 12. (Referred to as a signal) is transmitted to the television receiver 12.

  When receiving the instruction signal, the active standby television receiver 12 immediately shifts to the activated state.

  As described above, the television receiver 12 is provided with a plurality of standby states. Depending on the movement of the remote commander 11, the power consumption saving effect is great, but the standby state is long. Since the transition to the standby state where the effect of saving power consumption is small but the startup time is short, it is possible to effectively save the power consumption without forcing the user to set the standby state and The speed can be increased.

  Such processing of the remote commander 11 is referred to as activation control processing, and the processing of the television receiver 12 is referred to as activation processing.

  Next, a configuration example of the remote commander 11 and the television receiver 12 that realizes the activation control process and the activation process will be described with reference to FIG.

  The remote commander 11 includes a motion acceleration sensor 31, an operation unit 32, a microcontroller 33, and a communication unit 34.

  The motion acceleration sensor 31 is an acceleration sensor that detects three-axis acceleration, such as a horizontal X axis, a horizontal Y axis, and a vertical Z axis, as shown in FIG. The motion acceleration sensor 31 detects an acceleration value (acceleration magnitude) obtained by combining the three-axis accelerations, and supplies a sensor signal indicating the detected value (acceleration value) to the microcontroller 33.

  The operation unit 32 includes, for example, various buttons such as the power ON button 11A, a key, a dial, and the like, and supplies an operation signal corresponding to an operation by the user to the microcontroller 33.

  The microcontroller 33 includes, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The microcontroller 33 generates a detection signal, an instruction signal, and the like to be transmitted to the television receiver 12 based on the sensor signal supplied from the motion acceleration sensor 31 and the operation signal supplied from the operation unit 32, and the communication unit 34.

  The communication unit 34 transmits a signal supplied from the microcontroller 33 to the television receiver 12 by performing infrared communication or wireless communication with the television receiver 12 (the communication unit 51 thereof), for example. Note that the communication method between the remote commander 11 (the communication unit 34) and the television receiver 12 (the communication unit 51) is not limited to the above-described infrared communication and wireless communication, and may be any communication method. Can do.

  The communication unit 51 receives a signal transmitted from the remote commander 11 by, for example, performing infrared communication or wireless communication with the (communication unit 34) of the remote commander 11 and supplies the signal to the microcontroller 52.

  The microcontroller 52 controls each unit of the television receiver 12 based on a signal supplied from the communication unit 51 and the like.

  The microcontroller 52 that realizes the startup process includes a switching control unit 52A and a time measuring unit 52B. The switching control unit 52A controls the power input switching unit 54 based on a signal supplied from the communication unit 51. A control signal is generated and supplied to the power input switching unit 54. The time measuring unit 52B measures, for example, an elapsed time after shifting to a predetermined state.

  The power source 53 is a power source for the television receiver 12, and supplies power to the other hardware blocks through the power input switching unit 54 as well as to the communication unit 51 and the microcontroller 52.

  Based on the control signal supplied from the microcontroller 52, the power input switching unit 54 switches the switches I1, I2, I3, I4, I5, and I6 to either ON (supply) or OFF (stop), The power from the power supply 53 is supplied to each hardware block (for example, the tuner 56, the decoder 57, the display control unit 58, the display panel 59, the audio amplifier 60, and the speaker 61).

  During the deep standby, each switch of the power input switching unit 54 is turned off, that is, power from the power source 53 is supplied only to the communication unit 51 and the microcontroller 52. On the other hand, during active standby, the switches I 1, I 2, I 3, and I 5 of the power input switching unit 54 are turned on. That is, the power from the power source 53 is supplied to the tuner 56 in addition to the communication unit 51 and the microcontroller 52. The decoder 57, the display control unit 58, and the audio up 60 are supplied, but power is not supplied to the display panel 59 and the speaker 61.

  The antenna 55 receives a television broadcast wave such as a terrestrial analog broadcast, a terrestrial digital broadcast, or a BS (Broadcasting Satellite) digital broadcast, and supplies a broadcast signal corresponding to the television broadcast wave to the tuner 56.

  The tuner 56 performs processing such as channel selection and demodulation based on the broadcast signal supplied from the antenna 55, and supplies the broadcast signal obtained as a result to the decoder 57.

  The decoder 57 decodes the broadcast signal supplied from the tuner 56, and supplies image data obtained as a result to the display panel 59 and audio data to the audio amplifier 60.

  The display control unit 58 generates an image signal to be displayed on the display panel 59 based on the image data supplied from the decoder 57 and supplies the image signal to the display panel 59.

  The display panel 59 displays an image corresponding to the image signal supplied from the display control unit 58 on the display screen.

  The audio amplifier 60 amplifies the audio data supplied from the decoder 57 and supplies it to the speaker 61.

  The speaker 61 outputs sound corresponding to the sound data supplied from the audio amplifier 60.

  Next, the operation of the remote commander 11 in the activation control process will be described with reference to the flowchart of FIG.

  In step S <b> 1, the microcontroller 33 initializes a sensor detection parameter P for holding the detection value indicated by the sensor signal supplied from the motion acceleration sensor 31 to zero. The sensor detection parameter P is sequentially updated with a detection value indicated by a sensor signal supplied from the motion acceleration sensor 31.

  In step S <b> 2, the microcontroller 33 determines whether the motion acceleration sensor 31 has detected a sensor based on the sensor signal supplied from the motion acceleration sensor 31. For example, the microcontroller 33 determines whether or not the sensor has been detected based on whether or not the sensor detection parameter P that is sequentially updated with the detection value detected by the motion acceleration sensor 31 is, for example, a predetermined value or more.

  Specifically, for example, as shown in the left of FIG. 6, when the remote commander 11 is stationary on the floor, there is no movement in any of the three axes of the motion acceleration sensor 31, and the motion acceleration sensor Since the acceleration value detected at 31 is almost zero, the microcontroller 33 determines that there is no sensor detection. When the remote commander 11 is lifted by the user as shown in the right of FIG. 6, the remote commander 11 moves at an accelerated speed, so the acceleration value detected by the motion acceleration sensor 31 becomes a large value. The microcontroller determines that there has been sensor detection.

  If it is determined in step S2 that the sensor has been detected, that is, if the sensor detection parameter P is greater than or equal to a predetermined value, for example, in step S3, the microcontroller 33 determines whether the sensor detection parameter P is valid. judge. That is, for example, the microcontroller 33 determines that the sensor detection parameter P is valid only when the sensor detection parameter P is within a predetermined effective range (for example, a predetermined value or less). Thereby, even when an abnormal detection value is detected, it can be prevented that the sensor detection is erroneously determined.

  If it is determined in step S3 that the sensor detection parameter P is not valid, the process returns to step S1 and the microcontroller 33 initializes the sensor detection parameter P and performs the subsequent processing in the same manner.

  On the other hand, if it is determined in step S3 that the sensor detection parameter P is valid, in step S4, the microcontroller 33 controls the communication unit 34 to indicate that there has been sensor detection including the sensor detection parameter P. The sensor detection signal shown is transmitted to the television receiver 12. And it returns to step S2 and the subsequent processes are performed similarly.

  As will be described later, when receiving the sensor detection signal, the television receiver 12 shifts to active standby if it is in deep standby. That is, the sensor detection signal has a meaning as an instruction signal for instructing the television receiver 12 to shift to the active standby.

  On the other hand, if it is determined in step S2 that there is no sensor detection, that is, if the sensor detection parameter P is smaller than a predetermined value, for example, in step S5, the microcontroller 33 determines whether or not the power ON button has been pressed. judge. That is, for example, the microcontroller 33 determines whether or not an operation signal indicating that the power ON button has been pressed is supplied from the operation unit 32.

  If it is determined in step S5 that the power ON button has not been pressed, the process returns to step S2 and the subsequent processing is similarly performed.

  On the other hand, if it is determined in step S5 that the power ON button has been pressed, in step S6, the microcontroller 33 controls the communication unit 34 to instruct the power ON of the television receiver 12 to be turned on. Is transmitted to the television receiver 12. And it returns to step S2 and the process after it is performed similarly.

  In this example, the sensor detection signal is transmitted when it is determined in step S4 that the sensor detection parameter P is valid. However, in step S2, the validity determination in step S3 is not performed. If it is determined that the sensor has been detected, step S3 may be skipped, and the sensor detection signal may be transmitted in step S4.

  Next, the operation of the television receiver 12 in the startup process will be described with reference to the flowchart of FIG.

  The activation process is started, for example, when a transition is made to a standby state (deep standby or active standby).

  In step S41, the switching control unit 52A determines whether a signal is received from the remote commander 11. If it is determined in step S41 that no signal has been received from the remote commander 11, the process returns to step S41, and the subsequent processing is performed in the same manner.

  On the other hand, if it is determined in step S41 that a signal has been received from the remote commander 11, the switching control unit 52A determines in step S42 whether the signal received from the remote commander 11 is a sensor detection signal. If it is determined in step S42 that the signal received from the remote commander 11 is a sensor detection signal, in step S43, the switching control unit 52A determines whether or not it is in deep standby.

  If it is determined in step S43 that the device is not in deep standby, the process returns to step S41, and the subsequent processing is similarly performed.

  On the other hand, when it is determined in step S43 that deep standby is in progress, in step S44, the switching control unit 52A sends a control signal instructing the transition to active standby (from deep standby) to the power input switching unit 54. Supply. The power input switching unit 54 turns on the switches II, I2, I3, and I5 based on the control signal. As a result, power supply to the tuner 56 to the display control unit 58 and the audio amplifier 60 is started. Then, each hardware block for which power supply has started starts various settings based on, for example, control of the microcontroller 52.

  As a result, the television receiver 12 starts transition to a state where it can be activated instantly even though there are many hardware blocks (standby power is large) that are supplied with power from active standby, that is, deep standby.

  During active standby, the broadcast signal from the tuner 56 can be decoded by the decoder 57, so that an image or sound corresponding to the output of the decoder 57 is instantaneously displayed on the display panel 59 or speaker when the activation state is entered. 61 can be output. That is, during active standby, it can be said that the image is muted by the display control unit 58 and the audio is muted by the audio amplifier 60 in the previous stage of the speaker 61.

  In step S45, the time measuring unit 52B starts measuring the elapsed time from the start of the active standby.

  In step S46, the switching control unit 52A determines whether a power ON instruction signal is received from the remote commander 11. When it is determined in step S46 that the power ON instruction signal has not been received from the remote commander 11, in step S47, the switching control unit 52A determines the elapsed time from the start of active standby (preliminarily measured by the time measuring unit 52B). It is determined whether or not a set timeout time has been exceeded. If it is determined in step S47 that the time-out period has not been exceeded, the process returns to step S46, and the subsequent processing is similarly performed.

  On the other hand, when it is determined in step S47 that the time-out period has been exceeded, in step S48, the switching control unit 52A supplies the power input switching unit 54 with a control signal for instructing the transition to the deep standby (from active standby). . Based on the control signal, the power input switching unit 54 turns off the switches II, I2, I3, and I5, and stops supplying power to the tuner 56 to the display control unit 58 and the audio amplifier 60.

  Thereby, the television receiver 12 shifts to a deep standby state, that is, a so-called complete standby state in which standby power can be reduced most. And it returns to step S41 and the process after it is performed similarly.

  On the other hand, when it is determined in step S42 that the signal from the remote commander 11 is not a sensor detection signal, in step S50, the switching control unit 52A determines whether or not the signal from the remote commander 11 is a power ON instruction signal. judge. If it is determined in step S50 that the signal is not a power ON instruction signal, the process returns to step S41, and the subsequent processing is similarly performed.

  If it is determined in step S50 that the signal is a power ON instruction signal, or if it is determined in step S46 that a power ON instruction signal is received from the remote commander 11, in step S51, the switching control unit 52A is activated. A control signal instructing the shift to is supplied to the power input switching unit 54. The power input switching unit 54 turns on the switches I4 and I6 based on the control signal. Thereby, the supply of power to the display panel 59 and the speaker 61 is started. And it returns to step S41 and the process after it is performed similarly.

  Since various settings after the start of power supply are unnecessary or minimal in the display panel 59 and the speaker 61, when the power supply to these is started, the television receiver 12 is instantly activated. Migrate to

  As described above, for example, when the remote commander 11 is stationary on the floor, the television receiver 12 stands by in a deep standby where the standby power can be reduced most, and the remote commander 11 is picked up by the user by hand. If it is detected, when the movement of the remote commander 11 is detected and notified to that effect, the television receiver 12 automatically starts a transition to an active standby state in which it can be instantly activated. Then, for example, after about 1 second at the shortest, when the power ON button 11A of the remote commander 11 is operated by the user and notified to that effect, the television receiver 12 has shifted to active standby. The state immediately transitions to the activated state, and if not yet transitioned to the active standby, transitions to the activated state upon transition to the active standby. Therefore, it is not necessary for the user to perform setting work, and the startup can be speeded up easily while reducing standby power.

  Further, for example, when the television receiver 12 automatically shifts from the deep standby to the active standby against the user's expectation, such as when the user unintentionally moves the remote commander 11. However, even if the user's instruction is not received after a predetermined time, it automatically shifts to deep standby, so even if the user does not notice it when a misoperation or detection occurs, it will wait An increase in power can be suppressed.

  Next, a configuration example of another remote commander 81 to which the present invention is applied will be described with reference to FIG.

  In FIG. 8, the corresponding parts in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  A biological contact sensor 91 is added to the remote commander 81 of FIG. 8, and a microcontroller 92 is provided instead of the microcontroller 33 of the remote commander 11 of FIG. Other portions are denoted by the same reference numerals as those in the remote commander 11, and the description thereof is omitted as appropriate.

  As described above with reference to FIG. 1, the power ON button 1A of the remote commander 1 is operated in order to shift the television receiver 2 from the standby state to the activated state. In order to operate the power ON button 11A of 81, it is assumed that the living body contact sensor 91 is requested to hold a place.

  The remote commander 81 detects, for example, a living body contact caused by a user's finger or the like coming into contact with the living body contact sensor 91 and transmits a sensor detection signal indicating that the living body contact has been detected to the television receiver 12.

  The living body contact sensor 91 detects the presence or absence of living body contact, and when there is living body contact, supplies a sensor signal indicating that to the microcontroller 92.

  The microcontroller 92 is composed of, for example, a CPU, RAM, ROM, and the like. The microcontroller 92 generates detection signals, instruction signals, and the like to be transmitted to the television receiver 12 based on the sensor signals supplied from the motion acceleration sensor 31 and the biological contact sensor 91 and the operation signals supplied from the operation unit 32. It is generated and supplied to the communication unit 34.

  For example, when a sensor signal indicating that there is a biological contact is supplied from the biological contact sensor 91, the microcontroller 92 detects a sensor that includes an acceleration value detected by the motion acceleration sensor 31 at that time. The detection signal is transmitted to the television receiver 12 by controlling the communication unit 34.

  As described above, for example, when nothing is in contact with the biological contact sensor 91 of the remote commander 81, the television receiver 12 stands by in a deep standby state where standby power can be reduced most, and the biological contact sensor When the user's finger or the like touches 91, when the living body contact is detected and notified to that effect, the television receiver 12 automatically shifts to the active standby state in which it can be instantly activated. Start. When the power ON button 11A of the remote commander 81 is operated by the user and notified to that effect, the television receiver 12 immediately shifts to the activated state if it has shifted to active standby, and is still active standby. If it has not shifted to, it shifts to the active state as soon as it shifts to the active standby. Therefore, it is not necessary for the user to perform setting work, and the startup can be speeded up easily while reducing standby power.

  Next, a configuration example of another remote commander 111 to which the present invention is applied will be described with reference to FIG.

  In FIG. 9, the same reference numerals are given to the corresponding parts in FIG. 3, and the description thereof will be omitted as appropriate.

  The remote commander 111 in FIG. 9 is provided with a biometric fingerprint sensor 121 and a microcontroller 122 in place of the motion acceleration sensor 31 and the microcontroller 33 of the remote commander 11 in FIG. Other portions are denoted by the same reference numerals as those in the remote commander 11, and the description thereof is omitted as appropriate.

  As described above with reference to FIG. 1, the power ON button 1A of the remote commander 1 is operated to shift the television receiver 2 from the standby state to the start state. It is assumed that it is requested to touch the biometric fingerprint sensor 121 to operate the ON button 11A.

  The remote commander 111 detects, for example, a living body contact caused by a user's finger or the like coming into contact with the remote commander 111, and transmits a sensor detection signal indicating that the living body contact has been detected to the television receiver 12.

  The biometric fingerprint sensor 121 is a biometric fingerprint sensor for recognizing a biometric fingerprint. Further, for example, the biometric fingerprint sensor 121 detects the presence or absence of biometric contact depending on whether or not a biometric fingerprint is recognized. The biometric fingerprint information recognized together is supplied to the microcontroller 122.

  The microcontroller 122 is composed of, for example, a CPU, RAM, ROM, and the like. The microcontroller 122 generates a detection signal, an instruction signal, and the like to be transmitted to the television receiver 12 based on the sensor signal supplied from the biometric fingerprint sensor 121 and the operation signal supplied from the operation unit 32, and the communication unit 34.

  For example, when a sensor signal indicating that there is a biological contact is supplied from the biometric fingerprint sensor 121, the microcontroller 122 specifies the operator based on the biometric fingerprint information supplied together with the sensor signal. The microcontroller 122 that realizes the identification of the operator is configured to include the identification unit 122A. For example, the specifying unit 122A specifies the operator by checking the biometric fingerprint information supplied from the biometric fingerprint sensor 121 with the registered biometric fingerprint information. Then, for example, only when the specified operator is a predetermined user, the microcontroller 122 controls the communication unit 34 to transmit the sensor detection signal including the operator information to the television receiver 12. .

  As described above, for example, when nothing touches the biometric fingerprint sensor 121 of the remote commander 111, the television receiver 12 stands by in a deep standby state where the standby power can be reduced most, and the biometric fingerprint sensor When the user touches the user's finger or the like, the television receiver 12 automatically shifts to the active standby state in which it can be instantly activated at the stage when the biological contact is detected and notified to that effect. Start. When the power ON button 11A of the remote commander 111 is operated by the user and notified to that effect, the television receiver 12 shifts to an activated state if it has shifted to active standby, and still shifts to active standby. If it is not, it shifts to the active state as soon as it shifts to the active standby. Therefore, it is not necessary for the user to perform setting work, and the startup can be speeded up easily while reducing standby power.

  Further, the television receiver 12 transmits the sensor detection signal from the remote commander 111 to the television receiver 12 only when the operator identified by the identifying unit 122A is a predetermined user. When the user other than the predetermined user touches the biometric fingerprint sensor 121 unintentionally, it is possible to prevent the transition to the active standby automatically.

  A configuration example of another remote commander 141 to which the present invention is applied will be described with reference to FIG.

  Note that, in FIG. 10, the same reference numerals are given to corresponding portions in FIG. 3, and description thereof will be omitted as appropriate.

  The remote commander 141 in FIG. 10 is provided with a microphone 151 and a microcontroller 152 in place of the motion acceleration sensor 31 and the microcontroller 33 of the remote commander 11 in FIG. Other portions are denoted by the same reference numerals as those in the remote commander 11, and the description thereof is omitted as appropriate.

  As described above with reference to FIG. 1, the power ON button 1 </ b> A of the remote commander 1 is operated to shift the television receiver 2 from the standby state to the activated state. In this example, the user turns on the power of the remote commander 141. In order to operate the ON button 11A, the remote commander 141 is requested to emit some sound.

  For example, when a human voice is input from the microphone 151, the remote commander 141 transmits a detection signal indicating that a human voice has been detected to the television receiver 12.

  The microphone 151 inputs sound from the outside and supplies the sound information to the microcontroller 122.

  The microcontroller 152 includes, for example, a CPU, RAM, ROM, and the like. Based on the sound information supplied from the microphone 151 and the operation signal supplied from the operation unit 32, a detection signal and an instruction signal to be transmitted to the television receiver 12 are generated and supplied to the communication unit 34.

  For example, the microcontroller 152 performs voice recognition based on sound information supplied from the microphone 151 and identifies the user who has emitted the voice. The microcontroller 152 that realizes these components includes a voice recognition unit 152A and a specification unit 152B. The voice recognition unit 152A recognizes (human) voice from the sound information supplied from the microphone 151. The identification unit 152B identifies the operator by comparing the voice recognized by the voice recognition unit 152A with the registered voice. For example, only when the specified operator is a predetermined user, the microcontroller 152 controls the communication unit 34 to transmit a sensor detection signal including information on the operator to the television receiver 12.

  As described above, for example, when no human voice is emitted from the microphone 151 of the remote commander 141, the television receiver 12 stands by in a deep standby state where the standby power can be reduced most, and the remote commander When a human voice is recognized in 141, the television receiver 12 automatically starts transition to active standby, which is a state where it can be instantly activated, at the stage of being notified. Then, when the user operates the power ON button of the remote commander 141 and a notification to that effect is received, the television receiver 12 transitions to an active state if it has transitioned to active standby, and still transitions to active standby. If it has not shifted, it shifts to the active state as soon as it shifts to the active standby. Therefore, it is not necessary for the user to perform setting work, and the startup can be speeded up easily while reducing standby power.

  Further, the television receiver 12 transmits the sensor detection signal from the remote commander 141 to the television receiver 12 only when the operator specified by the specifying unit 152B is a predetermined user. When the user other than the predetermined user unintentionally utters sound to the microphone 151, it is possible to prevent the automatic transition to the active standby.

When a series of processing is executed by software, a program constituting the software executes various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a program recording medium in a general-purpose personal computer or the like.
