Description

  The present invention relates to an electronic device including a touch panel.

  In recent years, portable players that store music data in a storage medium such as a hard disk and process the music data with a CPU to reproduce music have been developed and put to practical use. Also, this type of portable player is required to be multi-functional in the same way as portable electronic devices such as mobile phones and digital cameras. For example, it may be possible to add a function for reproducing images together with music. It has been.

  On the other hand, the above-described portable player places importance on the design as a product, and is required to reduce even one extra switch from the device body in order to reduce the cost as much as possible. In view of this, a device has been devised to reduce the number of operation switches from the device main body by using the display unit as a touch panel and displaying various operation switches that increase with multifunction as GUI (Graphical User Interface) buttons on the touch panel.

However, since the touch panel is regarded as an input when the screen is touched, there is a high possibility that a malfunction occurs, for example, when the stop button is touched without the user being aware of it during music playback and the music playback stops. Therefore, conventionally, in order to prevent such a malfunction, a hold switch is provided in the device body, and when the hold switch is turned on, the touch panel input is disabled (see, for example, Patent Document 1). ).
Japanese Patent Laid-Open No. 2002-268776

  However, the hold switch cannot be released if it is a GUI button on the touch panel due to the nature of its function. Therefore, as with the power switch, a mechanical switch such as a slide switch can be used independently as a hold switch. I had to set it up. For this reason, in the conventional electronic device of this type, two types of mechanical switches, ie, a power switch and a hold switch, are the minimum required, and the request to reduce even one extra switch from the device body is sufficiently satisfied. I couldn't make it.

  The present invention has been made based on such circumstances, and an object of the present invention is to reduce mechanical switches provided in an electronic device having a touch panel.

The present invention displays an image and detects a touch operation input from a user, a push-type power switch provided separately from the touch panel, a normal operation mode capable of normal operation, and power saving An operation mode setting means capable of setting a stop operation mode, a hold switching means capable of switching between a hold state for invalidating an operation input from the touch panel and a hold release state for enabling, and the normal operation mode In some cases, when the push type power switch is operated for a predetermined time or longer, the operation mode setting means is controlled to shift the normal operation mode to the stop operation mode. the Ho and controls said holding switching means when it is a short time only operation than the predetermined time And control means for switching the de state and a hold release state, in which a notification means for informing using the light-emitting element that the predetermined time after the push-type power switch is operated has passed.

Further, it is desirable that the notification means blinks or lights up the light emitting element when a predetermined time has elapsed.

In addition, according to the present invention, the notification means causes the light emitting element to blink at the first cycle when a predetermined time has elapsed, and when the hold state is set in the normal operation mode, It blinks at a second period different from the one period.

According to the present invention, a storage unit for storing content, a function setting unit for setting a function corresponding to each type of content, and a control unit are provided in accordance with the function set by the function setting unit. It is desirable to control switching to the hold release state.

When the function set by the function setting unit is a music playback function capable of playing music content, the control unit permits switching to the hold state, and the function is an image processing function for processing a still image. It is desirable to control so that switching to the hold state is not permitted.

The present invention further includes external output means for outputting a video signal and / or audio signal to an external device, and the control means is interlocked with the switching operation between the hold state and the hold release state by the push-type power switch. It is desirable to include means for controlling whether to output video signals and / or audio signals from the external output means.

In this invention, it further comprises a connecting means for connecting to the cradle and a detecting means for detecting whether or not the cradle is connected, and the control means detects that the detecting means is connected to the cradle. It is only convenient to allow the output of video and / or audio signals from the external output means.

In this case, it is desirable that the signal output from the external output means is performed via a cradle.

  According to the present invention in which such means is provided, the power switch and the hold switch of the electronic device provided with the touch panel can be used together, and the number of mechanical switches necessary for the electronic device can be reduced.

The best mode for carrying out the present invention will be described below with reference to the drawings.
This embodiment is a case where the present invention is applied to a portable player with a digital camera function that reproduces contents such as music and images as an aspect of an electronic device including a touch panel.

  First, a first embodiment will be described with reference to FIGS. FIG. 1 is a front external view of the portable player 1 according to the first embodiment, FIG. 2 is a rear external view of the portable player 1, and FIG. 3 is a block diagram showing an overall configuration of the portable player 1 FIG.

  The portable player 1 is provided with a touch panel 11 and an indicator 12 as notification means on the surface of the housing 10. Further, the camera lens 13a of the imaging module 13 and the subject illumination device 14 are provided on the back surface. The touch panel 11 includes an LCD (Liquid Crystal Display) display device 111 that displays an image, an LCD illumination device 112 that is a backlight of the LCD display device 111, and a touch operation input device 113 that detects a touch operation input from a user. It is constituted by. The indicator 12 includes an LED (Light Emitting Diode) that is a light emitting element and a buzzer.

  Further, the portable player 1 is provided with a power switch 15 as a user operation means on the top surface of the housing 10. The power switch 15 is a mechanical switch such as a push-type switch, and also functions as a hold switch for instructing switching between a hold state that disables input of the touch panel 11 and a hold release state that enables it. .

  In addition, the portable player 1 is provided with an interface 16 as a connection means with a remote control device (hereinafter referred to as a remote control) provided in the headphones on one side surface of the housing 10, and a connection means with the cradle 17. The interface 18 is provided on the bottom surface. The cradle 17 functions as a docking station with an external device such as a personal computer, a television, or a printer, and also has a charging function. Therefore, the interface 18 with the cradle 17 is an AV (Audio And Visual) as an external output means for outputting a video signal and an audio signal to an external device in addition to an external communication interface unit 181 such as a USB (Universal Serial Bus). ) A signal output circuit 182 and a power supply circuit 183 are provided.

  The portable player 1 includes a CPU (Central Processing Unit) 19 as control means. Then, the CPU 19 is connected to the LCD illumination device 112, the LCD driver 21 that drives the LCD of the LCD display device 111, the touch operation input device 113, the power switch 15, the imaging module 13, the subject illumination device 14, and the The remote control interface 16, the indicator 12, the AV signal output circuit 182 and the power supply circuit 183 are connected. Also, an SDRAM (Synchronous Dynamic Random Access Memory) 20 as a working memory, an HDD device 23 as a storage means for storing contents such as music data and image data, and a nonvolatile storage for storing various parameters via the bus line 22. The flash memory 24 and the external communication interface unit 181 are connected to the CPU 19.

  In the portable player 1 having such a configuration, as an operation mode, a normal operation mode in which a normal operation can be performed, a sleep mode in which the clock is operated but the CPU 19 is not performed, a clock is stopped, and an operation input is not possible. Operation mode setting means capable of setting the power stop operation mode is provided. In addition, there is a hold switching means capable of switching between a hold state in which the input of the touch panel 11 is disabled and a hold release state in which the input is enabled.

  When the normal operation mode is set, as a function corresponding to each content type, a music playback function capable of playing back music content stored in the HDD device 23 and music stored in the HDD device 23 are provided. A music / image simultaneous reproduction function capable of simultaneously reproducing content and image content with an effect, and still images captured by the imaging module 13 are stored in the HDD device 23 or still images stored in the HDD device 23 Has a function setting means for selectively setting three functions of an image processing function that can be viewed and edited. In addition, when the normal operation mode is set, the dynamic content is not reproduced, and when there is no operation input for a predetermined time (for example, 3 minutes), the mode is shifted to the sleep mode.

  On the other hand, when the stop operation mode is set, as described above, the clock is stopped and no operation input is possible, so-called power-off state. However, the CPU 19 accepts only the interrupt input of the power switch 15.

  The processing procedure executed when the CPU 19 receives an interrupt input of the power switch 15 is shown in the flowchart of FIG. That is, when the power switch 15 is operated and a switch-on interrupt signal is input to the CPU 19, the CPU 19 counts the input time of the interrupt signal in steps S1 and S2. When a switch-on interrupt signal is input for a predetermined time (for example, 3 seconds), power on / off switching processing is executed in step S3. On the other hand, if the switch-on interrupt signal is interrupted within a predetermined time, hold-on / off switching processing is executed in step S4.

  FIG. 5 is a flowchart showing a specific processing procedure of the power on / off switching processing. When a switch-on interrupt signal is input for a predetermined time, the CPU 19 enters this power on / off switching process. First, in step S31, it is determined whether or not the current operation mode is the normal operation mode. If it is not the normal operation mode, that is, if it is the sleep mode or the stop operation mode, the operation mode is shifted to the normal operation mode in step S32, and this processing routine is exited.

  When the current operation mode is the normal operation mode in step S31, the CPU 19 causes the LED of the indicator 12 to blink at a high speed, for example, at a first cycle of 5 to 10 Hz (notification means) in step S33. The user is informed that the power is turned off when the finger is removed from the power switch 15. When the switch-on interrupt signal is interrupted because the finger is removed from the power switch 15 in step S34, the CPU 19 stops the blinking of the LED in step S35. Thereafter, in step S36, the operation mode is shifted to the stop operation mode (control means), and the process routine is exited.

  FIG. 6 is a flowchart showing a specific processing procedure of the hold on / off switching processing. The CPU 19 enters the hold on / off switching process when the switch-on interrupt signal is interrupted within a predetermined time. First, the current operation mode is determined in steps S41 and S42. If the operation mode is the stop operation mode, the process routine is exited. If it is in the sleep mode, the operation mode is shifted to the normal operation mode in step S43, and the process routine is exited.

  On the other hand, if it is the normal operation mode, the CPU 19 determines whether or not it is in the hold state in step S44. If not in the hold state, the CPU 19 sets the hold flag (F_HOLD) stored in the SDRAM 20 to “1” in step S45, and sets the hold state in step S46. An operation input from the touch panel 11 is not accepted and is invalidated (control means). In step S47, the LCD illumination device 112 is turned off and the display on the LCD display device 111 is turned off. Further, in step S48, the LED of the indicator 12 is blinked at a low speed (notification means) at a second cycle of, for example, a frequency of 0.5 to 1 Hz to notify the user that it is in the hold state. This is the end of this processing routine.

  On the other hand, if it is in the hold state in step S44, the CPU 19 stops the blinking of the LED in step S49. In step S50, the LCD illumination device 112 is turned on to turn on the display of the LCD display device 111. Thereafter, the hold flag (F_HOLD) is reset to “0” in step S51, and the hold state is canceled in step S52 so that an operation input from the touch panel 11 is accepted (control means). This is the end of this processing routine.

  In the portable player 1 according to the first embodiment configured as described above, when the operation mode is the stop operation mode in which the power is off, the user presses the power switch 15 for a predetermined time (for example, 3 seconds). ) When the above-mentioned long press operation is performed, the operation mode shifts to the normal operation mode. That is, the power is turned on. As a result, the user plays music content stored in the HDD device 23 using the portable player 1 (music playback function), or plays back image content stored in the HDD device 23 simultaneously with the music content. Thus, a slide show can be enjoyed (music / image simultaneous playback function), and a still image can be captured (image processing function) by the imaging module 13.

  When the user presses the power switch 15 for a short time for less than a predetermined time during the execution of the normal operation mode, the user enters the hold state, and the input from the touch panel 11 becomes invalid. Accordingly, for example, even if the stop button of the GUI button displayed on the touch panel 11 is accidentally touched during the reproduction of the music content, it is possible to prevent a malfunction such as the reproduction of the music content from being stopped.

  In the hold state, the LCD illumination device 112 is turned off, the display on the LCD display device 111 is turned off, and the LED of the indicator 12 blinks at a low speed. Thereby, the user can recognize easily that it is a hold state.

  Next, in this hold state, when the user presses the power switch 15 again for a short time less than a predetermined time, the hold state is canceled and the input from the touch panel 11 becomes valid. Further, the LCD illumination device 112 is turned on and the display of the LCD display device 111 is turned on, and the LED blinking operation of the indicator 12 is stopped. Thereby, the user can easily recognize that the hold state is released.

  In addition, during execution of the normal operation mode, if there is no operation input for a predetermined time (for example, 3 minutes) in a state where dynamic content is not reproduced, the operation mode shifts to the sleep mode. In the sleep mode, when the user performs a short press operation or a long press operation on the power switch 15, the normal operation mode is restored.

  Further, when the user presses and holds the power switch 15 for a predetermined time (for example, 3 seconds) during execution of the normal operation mode, the LED of the indicator 12 blinks at high speed. Accordingly, the user can know that the power is turned off when the finger is removed from the power switch 15. The user then lifts his finger from the power switch 15. Then, the blinking operation of the LED stops, and the operation mode shifts to the stop operation mode.

  As is clear from the above description, in the portable player 1 according to the first embodiment, the power switch 15 also functions as a hold switch. Accordingly, since it is not necessary to provide a hold switch in addition to the power switch 15 as a mechanical switch, the number of parts can be reduced, and the cost of the product and the simplification of the design can be realized.

  Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a block diagram showing the overall configuration of the portable player 1 according to the second embodiment, and parts that are the same as those in FIG. 3 are given the same reference numerals. As shown, the second embodiment is different from the first embodiment in that the signal of the power switch 15 is directly input not only to the CPU 19 but also to the power circuit 183.

  Further, the CPU 19 and the power supply circuit 183 also have different roles from the first embodiment. Hereinafter, this point will be described with reference to the flowcharts of FIGS.

  FIG. 8 is a flowchart showing a processing procedure when the power switch 15 is operated when the operation mode is the normal operation mode. That is, when the power switch 15 is operated and the switch-on interrupt signal is input to the CPU 19 in the normal operation mode, the CPU 19 counts the input time of the interrupt signal in steps S61 and S62. If the switch-on interrupt signal is interrupted for less than a predetermined time (for example, 3 seconds), the CPU 19 performs a hold-on / off switching process similar to that in the first embodiment (see FIG. 6) in step S63. ).

  On the other hand, when a switch-on interrupt signal is input for a predetermined time (for example, 3 seconds) or longer, the CPU 19 causes the LED of the indicator 12 to be turned on at a first cycle of, for example, a frequency of 5 to 10 Hz in step S64. Flashes and informs the user that power is turned off when the power switch 15 is removed. When the switch-on interrupt signal is interrupted because the finger is removed from the power switch 15 in step S65, the CPU 19 stops the blinking of the LED in step S66. In step S67, the value of the hold flag (F_HOLD) stored in the SDRAM is stored in the flash memory 24. After that, when the CPU 19 shifts the operation mode to the stop operation mode and executes end processing such as various savings in step S68, the power supply to the CPU 19 is stopped in step S69 and all processing is performed. finish.

  FIG. 9 is a flowchart showing a processing procedure when the power switch 15 is operated when the operation mode is the stop operation mode. That is, when the power switch 15 is operated and a switch-on signal is input to the power circuit 183 in the stop operation mode, the power circuit 183 is activated in step S71 and power is supplied to the CPU 19. . Thereby, CPU19 starts in step S72. In step S73, the CPU 19 sets the operation mode to the normal operation mode.

  Next, the CPU 19 reads the value of the hold flag (F_HOLD) stored in the flash memory 24 in step S74. If the value of the hold flag (F_HOLD) is “1” in step S75, that is, if the hold state has been set before the transition to the stop operation mode, the CPU 19 sets the hold state in step S76. The operation input from the touch panel 11 is invalidated. On the other hand, when the value of the hold flag (F_HOLD) is “0”, that is, when the hold state has not been set before the transition to the stop operation mode, the CPU 19 does not enter the hold state and the touch panel 11 Validate input.

  In the portable player 1 according to the second embodiment configured as described above, when the user presses the power switch 15 for a short time for less than a predetermined time during the operation in the normal operation mode, the hold state is set. The input of becomes invalid. In this hold state, when the user presses the power switch 15 again for a short time less than a predetermined time, the hold state is canceled and the input from the touch panel 11 becomes valid.

  Further, when the user presses and holds the power switch 15 for a predetermined time (for example, 3 seconds) during operation in the normal operation mode, the LED of the indicator 12 blinks at high speed. Accordingly, the user can know that the power is turned off when the finger is removed from the power switch 15. The user then lifts his finger from the power switch 15. Then, the blinking operation of the LED is stopped, and the operation mode is shifted to the stop operation mode. And after completion | finish processings, such as various evacuation, are performed, the electric power supply to CPU19 is stopped. That is, when entering the stop operation mode, the CPU 19 is completely stopped, which is different from the first embodiment. Therefore, only part of the power supply circuit 183 is operating in the stop operation mode.

  In addition, when the user performs a short press operation or a long press operation on the power switch 15 in the stop operation mode, a signal of the power switch 15 is directly input to the power circuit 183. As a result, the power supply to the CPU 19 is resumed, the CPU 19 is activated, and shifts to the normal operation mode.

  Therefore, also in the second embodiment, since the power switch 15 also functions as a hold switch, the same effect as that of the first embodiment can be obtained.

  In the second embodiment, the value of the hold flag (F_HOLD) stored in the flash memory 24 is read and set to “1” when the stop operation mode is shifted to the normal operation mode. If it is, the hold state is set. Therefore, even if the power switch 15 of the portable player 1 that has been put in a bag or the like in the stop operation mode is accidentally pressed and shifts to the normal operation mode, the hold state is maintained when the stop operation mode is transferred. Is set to a hold state and does not accept an input from the touch panel 11, it is possible to prevent malfunction.

  Next, a third embodiment of the present invention will be described with reference to FIG. Unlike the first embodiment, the third embodiment differs from the first embodiment in that the hold state is enabled only when the function operating in the normal operation mode is a music playback function. Since the overall configuration is the same as that of the first embodiment, a description thereof will be omitted with reference to FIG. Also, the processing procedure (FIG. 4) executed when the CPU 19 accepts the interrupt input of the power switch 15 and the specific processing procedure (FIG. 5) of the power on / off switching processing are the same as in the first embodiment. Therefore, the description thereof is omitted with reference to FIGS.

  FIG. 10 is a flowchart showing a specific processing procedure of hold-on / off switching processing according to the third embodiment. In addition, the same code | symbol is attached | subjected to the process step which is common in FIG. 6 which showed the process in 1st Embodiment, and detailed description is abbreviate | omitted.

  That is, the hold on / off switching process in the third embodiment is different from that in the first embodiment in the normal operation mode in step S41 and when the CPU 19 is not in the hold state in step S44, In step S81, it is determined whether the music playback function is being executed. Then, only when the music playback function is being executed, the processes of steps S45 to S48 are executed to set the hold state, and when other functions such as the music / image simultaneous playback function and the image processing function are being executed, the steps are performed. Each process of S45-S48 is not performed. That is, the hold state is not set.

  Even in the third embodiment having such a configuration, the power switch 15 also functions as a hold switch, and it goes without saying that the same effect as that of the first embodiment can be obtained. is there.

  In addition, in the third embodiment, the hold state setting is valid only when the music playback function is being executed. Accordingly, since the music / image simultaneous playback function and the image processing function are not executed, the hold state is not set, and the display of the LCD display device 111 is turned off because the hold state is set even though the image is being displayed. Unnecessary hold state setting can be prevented.

  Next, a fourth embodiment of the present invention will be described with reference to FIG. In the fourth embodiment, when a hold state is set during reproduction of image content or music content in the normal operation mode, an external device having a monitor function such as a television or a personal computer is connected to the cradle 17. As far as the first embodiment is concerned, the video signal of the image content and the audio signal of the music content are output via the cradle 17 so that the image can be viewed or listened to by the external device. Since the overall configuration of the type player 1 is the same as that of the first embodiment, description thereof will be omitted with reference to FIG. Also, the processing procedure (FIG. 4) executed when the CPU 19 accepts the interrupt input of the power switch 15 and the specific processing procedure (FIG. 5) of the power on / off switching processing are the same as in the first embodiment. Therefore, the description thereof is omitted with reference to FIGS.

  FIG. 11 is a flowchart showing a specific processing procedure of hold-on / off switching processing in the fourth embodiment. In addition, the same code | symbol is attached | subjected to the process step which is common in FIG. 6 which showed the process in 1st Embodiment, and detailed description is abbreviate | omitted.

  That is, the hold on / off switching process in the fourth embodiment is different from that of the first embodiment in the normal operation mode in step S41 and when the hold state is not in step S44, the CPU 19 After the processes in steps S45 to S48 are executed to set the hold state, it is detected in step S91 whether or not an external device such as a television or a personal computer is connected to the cradle 17 (detection means). If the connection is detected, the CPU 19 outputs the audio signal from the AV signal output circuit 182 during reproduction of the music content and the video signal during reproduction of the image content in step S92. The point is to output to the external device via the cradle 17.

  When the normal operation mode is set in step S41 and the hold state is not set in step S44, the CPU 19 executes AV processing in step S93 before executing the processes in steps S49 to S52 and releasing the hold state. It is determined whether or not one or both of the video signal and the audio signal is being output from the signal output circuit 182. If the signal is being output, a process of stopping all the signal output is executed in step S94. is there.

  Even in the fourth embodiment having such a configuration, the point that the power switch 15 also functions as a hold switch remains the same, and it goes without saying that the same effect as that of the first embodiment can be obtained. is there.

  In addition, in the fourth embodiment, when an external device such as a television or a personal computer is connected to the cradle 17 and the hold state is set during reproduction of image content or music content in the normal operation mode, Since the video signal or audio signal being reproduced is output to the external device via the external device 17, the user can view images and listen to music using the external device simply by performing a simple operation for setting the hold state. There is an effect.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the third embodiment, switching to the hold state is permitted only when the function being executed in the normal operation mode is the music playback function. However, when the music / image simultaneous playback function is being executed, Also, switching to the hold state may be permitted when a predetermined condition is met. Alternatively, when the music / image simultaneous playback function is being executed, when the power switch 15 is pressed for a short time, the music playback function may be automatically entered. When switching to the hold state is not permitted, the user may be warned that the hold state is not set by using the indicator 12 or the LCD display device 111.

  Moreover, in each said embodiment, although it alert | reported that predetermined time passed since the power switch 15 was operated by blinking LED, you may alert | report the same thing by lighting LED continuously. . Further, the buzzer may be sounded in synchronization with blinking or lighting of the LED. In each of the above embodiments, the predetermined time is set to 3 seconds, for example. Needless to say, this time is not limited to 3 seconds.

  The present invention is not limited to the portable player 1 and is an electronic device having a touch panel, which can be applied to all electronic devices in which a normal operation mode and a stop operation mode can be set as operation modes. It is. In this connection, the function corresponding to each type of content is not limited to the music playback function, the image processing function, and the like.
