Description

  The present invention relates to a remote control device and an image processing device that operates by receiving an instruction signal from the remote control device, and more particularly to a remote control device and an image processing device having a function indicating a button that can be operated in the remote control device.

  Today, remote control devices are widely used as devices for remotely operating image processing apparatuses such as televisions and videos. By using the remote control device, the user can perform various operations of the image processing device from a place away from the image processing device. In recent years, with the increase in functionality of image processing apparatuses and the spread of multifunction peripherals (for example, liquid crystal televisions with built-in DVD recorders) that combine a plurality of image processing apparatuses, the operation buttons provided on the remote control device tend to become complicated. .

  For example, in a liquid crystal television with a built-in DVD recorder that has recently become widespread, in addition to DVD playback or recording, a remote control device that selects a broadcast station received by the TV tuner, adjusts the volume, or sets a recording reservation, etc. Can be done.

  When operating an image processing apparatus having various functions as described above, sufficient operability cannot be obtained with a conventional remote control apparatus having a small number of operation buttons. For this reason, as the image processing apparatus becomes more complex, the number of operation buttons provided in the remote control device tends to increase.

  However, with the increase in the number of operation buttons, usable buttons and unusable buttons appear depending on the processing state of the image processing apparatus. In addition, even for the same button, a button whose function changes depending on the processing state on the image processing apparatus side also appears.

However, in this case, there is an image processing apparatus having a specification that prioritizes display of the recording reservation screen without executing reproduction processing. In this case, the user may misunderstand that the image processing apparatus or the remote control apparatus is broken because the reproduction process is not performed even though the reproduction button is pressed.

  In addition, for example, the button for performing the determination instruction on the recording reservation screen is an enter button, and the button for performing the determination instruction on the image quality adjustment screen is a space button. There is a case. For this reason, for example, a user who is unfamiliar with the operation presses the enter button on the image quality adjustment screen, and a response may not be obtained.

  In relation to the above problem, in Patent Document 1, when a user operates a remote control device that can simultaneously operate various types of electronic devices, which key can be operated (= operation button), A remote control device is disclosed that can easily determine which electronic device can be operated by operating the operation key.

The remote control device of Patent Literature 1 includes a plurality of mode switching keys for selecting an electronic device to be operated from a plurality of operable electronic devices, an operation key for operating the electronic devices, and an illumination for displaying the mode switching key. And illumination means for displaying the operation keys. When one mode switching key is pressed among the plurality of mode switching keys, the pressed mode switching key and the operation key for operating the electronic device selected by the mode switching key are made the same color by the illumination means. indicate.

Specifically, the backlight provided behind the operation button extracted by the operable button determination unit 31b (= the operation button for transmitting a remote control code that can be received by the liquid crystal television 1 with a built-in DVD recorder) is backlit. It is turned on by controlling the light 37. Further, the backlight of the operation button that has not been extracted by the operable button determination unit 31b is turned off. In addition, for an operation button that requires a long press operation to transmit a remote control code, the backlight 37 is controlled so that the backlight blinks repeatedly.

<1-5. Control buttons on the remote control device>
Here, the details of the operation button group 36 included in the remote control device 30 according to the first embodiment of the present invention will be described with reference to the schematic diagram of FIG.

  FIG. 7A is a schematic diagram illustrating an example of the operation button group 36 provided on the surface of the remote control device 30. As shown in FIG. 7A, the operation button group 36 includes a power button 41, a common button group 42, a mode switching button group 43, and a backlight mounting button group 44.

  The power button 41 is a button for transmitting a remote control code for activating the power source of the liquid crystal television 1 with a built-in DVD recorder. The common button group 42 is a function fixing button for transmitting a remote control mode that is always accepted if the liquid crystal television 1 with a built-in DVD recorder is in a power-on state. For example, an audio volume adjustment button corresponds to this. The mode switching button group 43 is used to switch between the DVD mode (= mode for viewing a DVD) and the TV mode (= mode for viewing a method received by the tuner) of the liquid crystal television 1 with a built-in DVD recorder. It is a button.

  The backlight-mounted button group 44 is a button for transmitting a remote control code that changes acceptability / impossibility depending on the processing state of the liquid crystal television 1 with a built-in DVD recorder, and has a backlight 37 behind it. The backlight mounting button group 44 is made of a transparent or translucent member, and therefore, the lighting of the backlight 37 can be visually confirmed. The backlight mounting button group 44 includes, for example, numeric buttons and cursor buttons.

  FIG. 7B shows an example in which a part of the backlight mounting button group 44 is turned on. In FIG. 7B, in the backlight mounting button group 44, four buttons at the center of the first stage, the left and right of the second stage, and the center of the third stage are lit. Therefore, only the four buttons are operable (= the operation buttons for transmitting a remote control code that can be received by the liquid crystal television 1 with a built-in DVD recorder).

  On the contrary, in the backlight mounted button group 44, the backlights of the buttons other than the above four buttons are turned off, so that the liquid crystal television 1 with a built-in DVD recorder does not accept the remote control code even if an operation with these buttons is performed. . Therefore, even if the user performs an operation, a response cannot be obtained.

<1-6. Acceptable code transmission process>
Here, the transmission process of the acceptable code performed by the liquid crystal television 1 with a built-in DVD recorder according to the first embodiment of the present invention to the remote control device 30 is shown in the block diagrams of FIGS. 1 and 3 and the flowchart of FIG. This will be described with reference to the screen diagrams and schematic diagrams of FIGS.

  FIG. 5 is a flowchart showing a process flow of the acceptable code transmission process according to the first embodiment of the present invention. This process is started when the control unit 11 detects the power activation of the liquid crystal television 1 with a built-in DVD recorder.

  The control unit 11 that has detected the power-on reads the remote control code management table from the hard disk 13 in step S110. Next, in step S120, the periodic determination unit 11b uses the processing state confirmation unit 11a to perform processing state confirmation processing for the liquid crystal television 1 with a built-in DVD recorder. As a result, the current processing state of the liquid crystal television 1 with a built-in DVD recorder, for example, the processing state such as the DVD playback process or the recording reservation setting screen display process is specified.

  Next, in step S130, the periodic discriminating unit 11b uses the remote control code management table to determine the receivable code that is one or a plurality of remote control codes that can be received from the remote control device 30 by the liquid crystal television 1 with a built-in DVD recorder in the specified processing state. Identify. For example, when the processing state is being reproduced, as shown in FIG. 10, the remote control code transmitted by pressing the “REW” button or the “FF” button is specified as an acceptable code. The identified acceptable code is given to the acceptable code transmitter 11c.

  In step S140, the receivable code transmitter 11c given the receivable code from the periodic determination unit 11b converts the identified receivable code into an infrared signal using the signal transmitter 18 and transmits it to the remote control device 30. To do.

  Next, in step S150, the control unit 11 determines whether a power stop command for the liquid crystal television 1 with a built-in DVD recorder has been detected. The power stop command is issued, for example, when the user presses a power button included in the operation button group 18. When the power supply stop command is detected, the control unit 11 transmits a power supply stop notification indicating that the power supply of the liquid crystal television 1 with a built-in DVD recorder has been stopped to the remote control device 30 using the signal transmission unit 18 in step S160. This process is terminated.

  On the other hand, if the power stop command is not detected in step S150, the periodic determination unit 11b determines in step S155 whether or not a predetermined time, for example, 1 second has elapsed since step S120 was performed. When it is determined that the predetermined time has elapsed, the process proceeds to step S120. If it is determined that the predetermined time has not elapsed, the process proceeds to step S150 and the same process is repeated.

<1-7. Acceptance code reception process>
Here, the reception process of the acceptable code performed by the remote control device 30 according to the first embodiment of the present invention is illustrated in the block diagrams of FIGS. 2 and 4, the flowchart of FIG. 6, and the schematic diagram of FIG. This will be described with reference to the screen diagrams and schematic diagrams of FIGS.

  FIG. 6 is a flowchart showing the process flow of the reception process of the acceptable code according to the first embodiment of the present invention. This processing is started when the power source of the liquid crystal television 1 with a built-in DVD recorder is activated and becomes operable by the remote control device 30.

  In the remote control device 30 in the operable state, the receivable code receiving unit 31a determines whether or not an infrared signal including information regarding the receivable code is received from the liquid crystal television 1 with a built-in DVD recorder in step S210. The infrared signal is received using the signal receiving unit 34, and the received signal is converted into information and given to the acceptable code receiving unit 31a. The receivable code receiving unit 31a given the information determines whether there is information regarding the receivable code in the information.

  In step S210, when the reception of the infrared signal including the information regarding the acceptable code is not detected, the process of step S210 is continued. On the other hand, when reception is detected, the acceptable code receiving unit 31a gives the received acceptable code to the operable button determination unit 31b. In step S220, the operable button determination unit 31b extracts an operation button used for outputting the remote control code indicated by the given acceptable code from the operation button group 36. Specifically, the operation button is extracted by reading out from the ROM 33 and referring to the association information indicating the relationship between each remote control code and the operation button used for transmitting each remote control code.

  Next, in step S230, the backlight lighting unit 31c turns on the backlight 37 provided on the back of the operation button extracted by the operable button determination unit 31b. Thereby, for example, the operation button group in the state of FIG. 7A changes to the state of FIG. In the example shown in FIG. 7, since all the buttons of the backlight mounting button group 44a and the backlight mounting button group 44c are lit, it is indicated that the operation is possible. Further, the backlight mounted button group 44b in which the backlight is not turned on indicates that the operation cannot be performed, that is, even if the operation is performed and the remote control code is transmitted, the liquid crystal television 1 with a built-in DVD recorder does not accept it.

  Next, in step S240, the operable button determination unit 31b determines whether there is an operation button in the operation button group 36 that requires a long press operation to output the remote control code indicated by the given acceptable code. . This determination is also made by reading and referring to the association information recorded in the ROM 33. If there is no operation button that requires a long press operation, the process proceeds to step S270 described later.

  Conversely, if there is an operation button that requires a long press operation, the backlight lighting unit 31c blinks the backlight 37 provided on the back of the long press button extracted by the operable button determination unit 31b in step S250. . In addition, although it is desirable that the ratio of the length of the lighting time and the extinguishing time at the time of blinking is 1: 1, it may be changed as appropriate.

  Next, in step S260, the control unit 31 determines whether or not a power stop of the liquid crystal television 1 with a built-in DVD recorder is detected. The detection of the power supply stop of the liquid crystal television 1 with a built-in DVD recorder is received by using the signal receiving unit 34, for example, a power supply stop notification (see step S160 in FIG. Is done. Alternatively, the power supply stoppage may be detected when a response to the remote control code transmitted from the remote control device 30 cannot be detected.

  If it is not detected in step S260 that the power to the liquid crystal television 1 with a built-in DVD recorder has been detected, the process returns to step S210. On the contrary, when the power supply stop is detected, the control unit 31 turns off all the backlights 37 in step S270 and ends the present process.

<1-8. Acceptable code transmission processing and reception processing results>
Here, regarding the results of the acceptable code transmission processing and reception processing performed by the DVD recorder built-in liquid crystal television 1 and the remote control device 30 according to the first embodiment of the present invention, the screen diagrams and schematics of FIGS. This will be described with reference to the drawings.

  FIG. 8A shows an example of a menu screen displayed by the liquid crystal television 1 with a built-in DVD recorder of the present invention using the OSD generation unit 21. FIG. 8B is a schematic diagram showing an example of a backlight-mounted button group 44 that can be operated on the menu screen of FIG. In FIG. 8B, a button that is grayed out (for example, “UP”) is lit by an LED.

  In the example illustrated in FIG. 8A, the operation cursor is set to “LANGUAGE” on the menu screen. This is a setting item for designating a language used for OSD display. The buttons that can be operated in this state are determined by the remote control code management table recorded in the control unit 11 and the hard disk 13 and sent to the remote control device 30. As a result, the backlight of four buttons such as the “LEFT” button included in the backlight mounting button group 44 of the remote control device 30 is turned on.

  In this state, every time the user presses the “RIGHT” button, for example, “LANGUAGE” is switched in a predetermined order such as “ENGLISH” → “JAPANESE” → “DUTCH”. In this state, the user moves the cursor by pressing the “UP” button and the “DOWN” button included in the backlight mounting button group 44 and shifts to an item setting other than language selection (for example, “TIME SEARCH”). ).

  On the contrary, in this state, even if the “ENTER” button or the “RETURN” button is pressed, the operation is invalidated because there is no target that can be operated by these buttons on the menu screen. For this reason, in FIG. 8B, these buttons are turned off.

  FIG. 9A is an example of a menu screen as in FIG. 8A. FIG. 9B is a schematic diagram showing an example of a backlight-mounted button group 44 that can be operated on the menu screen of FIG. 9A, as in FIG. 8B. FIG. 9 shows a screen when the processing state of the liquid crystal television 1 with a built-in DVD recorder changes when the “DOWN” button in FIG. 8 is pressed once, and the state of the buttons of the remote control device 30.

  In the example shown in FIG. 9A, the operation cursor is set to “TIME SEARCH” on the menu screen. This is an item for performing a time search function (= a function for skipping a reproduction start point to an arbitrary position by specifying a time). When the state processing confirmation unit 11 a detects that the cursor is positioned here, the remote control code management table is referred to and a receivable code is sent to the remote control device 30. As a result, the backlight of the three buttons such as the “UP” button is turned on.

  In this state, when the user presses an “ENTER” button included in the backlight mounting button group 44, a time search screen (not shown) is displayed. Further, the cursor can be moved by pressing the “UP” button and the “DOWN” button included in the backlight mounting button group 44 to shift to an item other than the time search function (for example, “LANGUAGE”). Is possible.

  On the other hand, in this state, even if the “LEFT” button, “RIGHT” button, or “RETURN” button is pressed, the operation is invalidated because there is no target that can be operated with these buttons on the menu screen. End up. For this reason, in FIG. 9B, these buttons are turned off.

  FIG. 10A shows an example of a playback screen when information read from the DVD medium is played back using the optical disk drive 17. FIG. 10B is a schematic diagram showing an example of a backlight-mounted button group 44 that can be operated on the reproduction screen of FIG. Note that the DVD medium being reproduced here is a reproduction-only disk, and recording on the DVD medium is not possible.

  In the example shown in FIG. 10A, “PLAY” indicating that playback is in progress is displayed on the DVD playback screen. In this state, the user can operate the “STOP” button for stopping playback, the “FF” button for fast-forwarding, the “REW” button for reverse playback, and the “PAUSE” button for pause. For this reason, in FIG. 10B, these four buttons are lit.

  On the contrary, in this state, an operation using the “REC” button for instructing recording and the “PLAY” button for instructing playback are impossible. Because DVD media is exclusively for playback, recording by the “REC” button cannot be performed. Also, since the playback process has already been started, it does not make sense to press the “PLAY” button for instructing the start of playback. For this reason, in FIG. 10B, these buttons are turned off.

If the remote control code is not detected, step S101 is repeated until it is detected.

  Conversely, when remote control code reception is detected, the state change determination unit 11d determines whether or not the processing state of the liquid crystal television 1 with a built-in DVD recorder changes according to the received remote control code. As a specific method for performing the determination, for example, an association table in which each remote control code and a change in the processing state caused by each remote control code are recorded in association is recorded in advance on the hard disk 13, and the association table is read and referred to. To do. Note that examples of the remote control code that causes a change in the processing state include a remote control code for instructing TV / DVD mode switching.

  If it is determined in step S102 that a change in the processing state occurs due to the received remote control code, the process proceeds to the next step S110. On the other hand, when it is determined that the processing state does not change, the process proceeds to step S101 again.
