  Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following description. In addition, constituent elements in the following description include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in a so-called equivalent range. In the following, a mobile phone will be described as an example of a portable electronic device which is an example of a character input device. However, the application target of the present invention is not limited to a mobile phone. For example, PHS (Personal Handyphone System) The present invention can also be applied to portable navigation devices, game machines, and the like. In the embodiment described below, a case where a one-segment partial reception service for mobile phones / mobile terminals, so-called one-segment broadcasting, is received as a broadcast wave will be described, but the broadcast wave is not limited to this. As the broadcast wave, for example, it can also be used in the case of 12-segment terrestrial digital broadcast, analog broadcast, and digital radio broadcast.

  FIG. 1 is a front view showing a schematic configuration of an embodiment of a portable electronic device which is an example of a character input device of the present invention. FIG. 2 is a side view of the portable electronic device shown in FIG. First, the configuration of the portable electronic device will be described. The mobile electronic device 1 is a mobile phone having a wireless communication function. The portable electronic device 1 is a cycloid type mobile phone in which a housing 1C is configured to be openable / closable and rotatable by a first housing 1CA, a second housing 1CB, and a third housing 1CC. 1 and 2 show a state where the portable electronic device 1 is opened and not rotated. In the present embodiment, the casing is a cycloid type casing, but the shape of the casing is not particularly limited, and can be various shapes such as a folding type, a sliding type, and a single type.

  The first housing 1CA is provided with a main display 2M shown in FIG. 1 as a display unit. The main display 2M displays a standby image as a predetermined image when the portable electronic device 1 is waiting for reception, or a menu image used to assist the operation of the portable electronic device 1. Or As shown in FIG. 1, the first housing 1CA is provided with a receiver 6 that emits a voice when the mobile electronic device 1 is in a call.

  The second casing 1CB is provided with a plurality of operation keys 3 for inputting characters at the time of composing a telephone number, mail, etc., and selecting and determining menus and screens displayed on the main display 2M. A direction and a determination key 4 are provided for easily executing scrolling and the like. The operation key 3 and the direction / decision key 4 constitute an operation unit 28 (see FIG. 3) of the portable electronic device 1. In addition, the second housing 1CB is provided with a microphone 5 that receives sound when the mobile electronic device 1 is in a call.

  The first housing 1CA and the second housing 1CB are connected by a third housing 1CC. The third housing 1CC is connected to the second housing 1CB in an openable / closable state, and is connected to the first housing 1CA in a rotatable state. Specifically, the first housing 1CA is supported by the third housing 1CC so as to rotate relatively with an axis orthogonal to the main display 2M as a rotation axis. Further, the second housing 1CB and the third housing 1CC are connected by a hinge 18. As a result, the first housing 1CA and the second housing 1CB (and the third housing 1CC) are orthogonal to the main display 2M around the connecting portion between the second housing 1CB and the third housing 1CC. It is rotated around the axis (direction indicated by arrow R1 in FIG. 1). Further, the first casing 1CA (and the third casing 1CC) and the second casing 1CB rotate together around the connecting portion (that is, the hinge 18) between the second casing 1CB and the third casing 1CC. Thus, it is configured to be able to rotate in a direction away from each other and a direction approaching each other (direction indicated by an arrow R2 in FIG. 2). When the first casing 1CA and the second casing 1CB rotate in a direction away from each other, the portable electronic device 1 opens, and when the first casing 1CA and the second casing 1CB rotate in a direction approaching each other, the portable electronic device 1 opens. Device 1 closes.

  Next, the relationship between the function of the portable electronic device 1 and the control unit will be described. FIG. 3 is a block diagram showing a schematic configuration of functions of the portable electronic device shown in FIG. As shown in FIG. 3, the mobile electronic device 1 includes a main control unit 22, a storage unit 24, a communication unit 26, an operation unit 28, an input data acquisition unit 29, an audio processing unit 30, and a display unit 32. The display control unit 33 and the one-segment receiving unit 36 are provided.

  The main control unit 22 is a processing unit that centrally controls the overall operation of the mobile electronic device 1, for example, a CPU (Central Processing Unit). That is, the communication unit 26, the display unit, and the like so that various types of processing of the portable electronic device 1 are executed in an appropriate procedure according to the operation of the operation unit 28 and the software stored in the storage unit 24 of the portable electronic device 1. 32, controls the operation of the one-segment receiver 36 and the like. The main control unit 22 executes processing based on programs (for example, operating system programs, application programs, etc.) stored in the storage unit 24. The storage unit 24 stores software and data used for processing in the main control unit 22. Specifically, it is used for extraction of conversion candidates at the time of character conversion, software that performs television broadcasting based on data received by the one-segment receiver 36, software that performs character input processing, software that transmits / receives mail, and the like. Dictionary data to be stored is stored.

  The communication unit 26 establishes a radio signal line by a CDMA system or the like with a base station via a channel assigned by the base station, and performs telephone communication and information communication with the base station.

  The operation unit 28 includes, for example, an operation key 3 to which various functions such as a power key, a call key, a numeric key, a character key, a direction key, a determination key, and a call key are assigned, and a direction and determination key 4. When these keys are input by a user operation, a signal corresponding to the operation content is generated. The generated signal is input to the input data acquisition unit 29 as a user instruction.

  The input data acquisition unit 29 generates a control signal based on the signal generated from the operation unit 28 and the input setting, and inputs the generated control signal to the main control unit 22. For example, in the case of character input, one character is extracted from characters assigned to each key based on the number of times each key of the operation key 3 is operated, and is output to the main control unit 22 as character information. In the present embodiment, the operation keys 3 are composed of 15 keys, of which 10 keys are assigned such that 1 to 9 and 0 are input in the mode for inputting numbers. Yes. Furthermore, keys assigned with numbers 1 to 9 are assigned so that characters in lines are entered from line to line in the character input mode. It is assigned to input "Wa", "O", and "N". In addition, the key to which each line is assigned is also assigned the roar of that line and the above-mentioned numbers. The characters assigned to these keys have a predetermined arrangement order. Specifically, the “1 a” key to which “A” and “1” are assigned is “A”, “I”, “U”, “E”, “O”, “A”, “I”, “ Arrangement order of “ぅ”, “e”, “ぉ”, “1” is set. The order of arrangement is toggled. That is, the characters assigned to the keys are set so as to circulate, and “1” is followed by “a”, and then the arrangement order is repeated. In the case of channel operation, the pressed key is detected, and channel information (broadcast station selection information) corresponding to the key is output to the main control unit 22. That is, when the operation key “1” is pressed, information on the channel corresponding to “1” is sent to the main control unit 22. In addition, both may be set so that a plurality of key presses correspond to channel information.

  Further, the input data acquisition unit 29 detects pressing of the operation key 3 and determines a character to be displayed (selected) among characters in the arrangement order based on the number of pressings. When the same operation key 3 is pressed continuously, that is, when the same operation key 3 as that immediately before (exactly one key among the operation keys 3) is pressed, the input data acquisition unit 29 A character (input candidate character) to be displayed in the arrangement order is selected based on the number of times of pressing. Further, the input data acquisition unit 29 operates when a different operation key 3 is pressed, that is, an operation key 3 different from the operation key 3 pressed immediately before (precisely, one key among the operation keys 3). When is pressed, the first character in the arrangement order of the pressed operation keys 3 is displayed.

  The audio processing unit 30 executes processing of an audio signal input to the microphone 5 and an audio signal output from the receiver 6.

  The display unit 32 includes a display panel (such as the main display 2M described above) configured by a liquid crystal display (LCD, Liquid Crystal Display), an organic EL (Organic Electro-Luminescence) panel, and the like. A video corresponding to the video data supplied via the unit 33 and an image corresponding to the image data are displayed on the display panel.

  The one seg receiving unit (one seg tuner) 36 has a terrestrial digital broadcast having a plurality of channels, in the present embodiment, a TV antenna for receiving radio waves of a predetermined channel of the one seg broadcast, To the main control unit 22. As an example, the one-seg receiving unit 36 performs signal processing such as amplification, detection, and frequency conversion on the received signal received by the TV antenna by the tuning device, and a digital signal, MPEG-2 TS (Transport Stream) in this embodiment. ) And output to the main control unit 22. The output digital signal is processed by an application program driven by the main control unit 22 and displayed on the display of the display unit 32 or stored in the storage unit 24. Audio is output from a receiver or a separately provided speaker.

  Next, the operation of the portable electronic device 1, the operation input to the operation unit 28, and the processing in the main control unit 22 will be described. Here, FIG. 4 is a flowchart showing an example of the processing operation of the portable electronic device. Note that the flowchart shown in FIG. 4 is a flowchart illustrating an example of processing when an operation key is pressed during display of one-segment broadcasting. In the example shown in FIG. 4, a one-digit number is assigned to each channel of the one-segment broadcasting, and a channel change instruction can be input by pressing one button of the operation keys.

  First, the portable electronic device 1 is operated by the operator, and an instruction to start 1Seg is input. When an instruction to activate one seg is input, the main control unit 22 of the portable electronic device 1 performs a one seg activation process as step S12. The one-seg activation process is to read and activate software for performing television broadcasting from the storage unit 24, receive the television broadcast radio wave by the one-seg receiving unit 36, convert the received radio wave, and display the image on the display unit 32. This is a process for outputting sound from the receiver 6 or the speaker.

  After performing the one seg activation process in step S12, the main control unit 22 determines whether a key press interruption has been detected in step S14. That is, it is determined whether the operation unit 28 is operated by the operator.

  If the main control unit 22 determines in step S14 that no key press interrupt has been detected (No), the main control unit 22 proceeds to step S14 again and determines whether a key press interrupt has been detected. That is, the main control unit 22 repeats the process of step S14 while outputting the television broadcast received by the one-segment receiving unit 36 until detecting a key press interruption.

  Next, if the main control unit 22 determines in step S14 that a key press interruption has been detected (Yes), the main control unit 22 turns on the timer in step S16. When the timer is turned on, it measures the time since it was turned on, that is, the elapsed time after detecting the key press.

  If the timer is turned on in step S16, the main control unit 22 starts channel change processing in step S18. Specifically, the main control unit 22 starts a process of switching the television broadcast to be output to the television broadcast of the channel corresponding to the key pressed in step S14. After starting the channel change process in step S18, the main control unit 22 performs a new channel data reception process in step S20. That is, the main control unit 22 starts the process of receiving and outputting the television broadcast data corresponding to the channel changed in step S18 by the one-segment receiving unit 36.

  When the main control unit 22 starts receiving the new channel data (that is, the TV broadcast data of the new channel) in step S20, the main control unit 22 determines in step S22 whether a predetermined time has elapsed. Here, whether or not the predetermined time has elapsed is determined based on whether or not the elapsed time of the timer turned on in step S16 is the set time. If the main control unit 22 determines that the predetermined time has passed (Yes), the main control unit 22 performs channel change confirmation processing as step S23, and then proceeds to step S40. Here, the channel change confirming process is a process for confirming the channel for which data reception is started in step S20 as the TV broadcast channel to be output. Thereby, the television broadcast of the channel determined in step S23 is output until a new channel change process is input thereafter. When the process of step S23 ends, the control unit 22 proceeds to step S40.

  If it is determined in step S22 that the predetermined time has not elapsed (No), the main control unit 22 determines in step S24 whether a key press interruption has been detected. That is, it is determined whether a key press different from the key press in step S14, that is, a second key press is detected.

  If the main control unit 22 determines in step S24 that no key press interruption has been detected (No), the main control unit 22 proceeds to step S22. That is, the main control unit 22 repeats step S22 and step S24 until a key press interruption is detected before a predetermined time elapses.

  If the main control unit 22 determines in step S24 that a key press interruption has been detected (Yes), it returns the channel to the original display channel in step S30. That is, the television broadcast data of the channel is received as the channel displayed before the channel change process is started in step S18, and the output of the television broadcast of the channel is started. The processing of step S18 and step S20 is stopped, and the TV broadcast channel to be output is returned to the channel before step S18.

  After returning the channel to the original display channel in step S30, the main control unit 22 changes the one-segment display size in step S32. That is, the area of the television broadcast screen displayed on the display unit 32 is reduced.

  When the one-segment display size is changed in step S32, the main control unit 22 immediately activates the character input screen as step S34. Here, the immediate character input screen is a screen for displaying the input character information, and is displayed on the display unit 32 together with the television broadcast screen.

  When the character input screen is activated immediately in step S34, the main control unit 22 displays characters created by key input in step S36. Specifically, the character corresponding to the key operation input in step S14 and step S24 is displayed.

  When the main control unit 22 displays characters in step S36, the main control unit 22 performs character processing immediately in step S38. Here, the immediate character processing is processing for displaying a character corresponding to the input key operation and converting the input character for which a conversion operation has been detected into kanji, katakana, a symbol, or the like. Further, in the immediate character processing, a schedule function, an address book function, a memo function, and the like are activated as necessary, and the input character string is stored in the storage unit 24 corresponding to each function. The main control unit 22 proceeds to step S40 as soon as the character processing is completed.

  When the process of step S23 or step S38 is completed, the main control unit 22 determines whether there is a one-segment end instruction as step S40. If the main control unit 22 determines in step S40 that there is no termination instruction (No), the main control unit 22 proceeds to step S14 and repeats the above operation while outputting a television broadcast. If the main control unit 22 determines in step S40 that there is a one-segment end instruction (Yes), the main control unit 22 terminates the one-segment operation in step S42 and ends the process. That is, the main control unit 22 ends the output of the television broadcast and ends the process.

  Hereinafter, the change of the display unit will be described with reference to FIG. Here, FIG. 5 is an explanatory diagram for explaining the operation of the portable electronic device. First, when one seg is activated in step S12, the television broadcast of the set channel is displayed on the display unit 32 as shown at the left end in FIG. From this state, for example, when “5” of the operation key 3 is pressed, the key press is detected in step S14, and the channel change process is started in step S18. When the channel change process is started, the display unit 32 displays “Receiving...” Indicating that the channel is being changed and the television broadcast data of a different channel is being received, as shown in the center of FIG. Message is displayed.

  Thereafter, when a predetermined time has passed without detecting a key pressing operation, a channel change confirmation process is performed in step S23, and as shown in the upper right in FIG. 5, the channel is switched (in the example shown in FIG. 5, the operation key 3 TV channel of the channel corresponding to “5”) is output. On the other hand, if a key press operation is further detected during channel switching, that is, before a predetermined time elapses, a character input screen is immediately displayed as shown in the lower right in FIG. In the example shown in FIG. 5, since “5” of the operation key 3 is pressed, “5” of the operation key 3 is pressed twice, and “Ni” corresponding to this operation is input. Displayed on the screen. At this time, the one-segment screen (screen for outputting television broadcast) is reduced in size, and further, the television broadcast image of the channel before the operation key 3 is pressed is displayed.

  In this way, if there is more than one key press within a certain time during 1Seg activation, it is determined as a character input operation, the character input screen is displayed, and the operator can enter the character. Even while watching TV broadcasting, it is possible to input characters with a simple operation. As a result, it is possible to write a memo or look up kanji while watching a television broadcast. In addition, since it is not necessary to start up the memo function after the television broadcast is once ended, the operability can be improved. Furthermore, it is possible to make it easier to take notes on the contents of television broadcasts. In addition, it is not necessary to perform a special input operation in order to activate the character input function by determining whether the character input operation is performed by a key press operation, and a part of the operation keys is activated. There is no need to allocate for. Thereby, it is not necessary for the operator to memorize a special operation, and the configuration of the operation key can be simplified.

  Also, by identifying whether the channel is changed or the character is input based on the number of key pressing operations, both operations can be performed with one operation key. In this embodiment, it is determined that the character input is performed when two key presses are detected within a predetermined time. However, the reference count may be set according to the maximum input count of the channel operation. For example, when a two-digit number is assigned to a TV broadcast channel, it is determined that the character is input when the key is pressed three times or more within a predetermined time, and the channel operation is determined when the key is pressed twice or less. You just have to do it.

  In the above embodiment, the channel change process is started when the key press operation is detected in step S14. However, the present invention is not limited to this, and the key press is detected after the first (predetermined) key press is detected. Alternatively, the channel change process may be started after a certain time has elapsed. Hereinafter, a description will be given with reference to FIG. Here, FIG. 6 is a flowchart showing another example of the processing operation of the portable electronic device. Note that the flowchart shown in FIG. 6 includes steps for performing the same processing as the flowchart shown in FIG. Therefore, in the following, steps that perform the same processing as the steps shown in FIG. 4 are denoted by the same step numbers, detailed description thereof will be omitted, and processing specific to the flowchart shown in FIG. I will explain it.

  First, the portable electronic device 1 is operated by the operator, and an instruction to start 1Seg is input. When an instruction to activate one seg is input, the main control unit 22 of the portable electronic device 1 performs a one seg activation process as step S12. After performing the one seg activation process in step S12, the main control unit 22 determines whether a key press interruption has been detected in step S14. If the main control unit 22 determines in step S14 that no key press interrupt has been detected (No), the main control unit 22 proceeds to step S14 again and determines whether a key press interrupt has been detected.

  Next, if the main control unit 22 determines in step S14 that a key press interruption has been detected (Yes), the main control unit 22 turns on the timer in step S16. When the timer is turned on in step S16, the main control unit 22 determines whether a certain time has passed as step S22.

  If the main control unit 22 determines that the predetermined time has passed (Yes), the main control unit 22 starts the channel change process as step S50. Specifically, the main control unit 22 starts a process of switching the television broadcast to be output to the television broadcast of the channel corresponding to the key pressed in step S14. After starting the channel change process in step S50, the main control unit 22 performs a new channel data reception process in step S52. That is, the main control unit 22 starts the process of receiving and outputting the television broadcast data corresponding to the channel changed in step S50 by the one-segment receiving unit 36.

  When the main control unit 22 starts receiving the new channel data (that is, the new channel television broadcast data) in step S52, the main control unit 22 performs a channel change confirmation process in step S54, and then proceeds to step S40. Here, the channel change confirmation process is a process of confirming the channel for which reception of data has been started in step S52 as an output television broadcast channel. Thereby, the television broadcast of the channel determined in step S54 is output until a new channel change process is input thereafter.

  If it is determined in step S22 that the predetermined time has not elapsed (No), the main control unit 22 determines in step S24 whether a key press interruption has been detected. If the main control unit 22 determines in step S24 that no key press interruption has been detected (No), the main control unit 22 proceeds to step S22.

  If the main control unit 22 determines in step S24 that a key press interrupt has been detected (Yes), the main control unit 22 changes the one-segment display size in step S32. That is, the area of the television broadcast screen displayed on the display unit 32 is reduced. In the following, the processing from step S32 to the end of processing is the same as the processing in the flowchart shown in FIG.

  As shown in the flowchart of FIG. 6, by starting the channel change process after confirming that the channel change operation is being performed, the screen is restored to the original in the case of a character input operation (immediate character process). There is no need to return to the channel. That is, it is not necessary to perform the process of step S30 in the flowchart shown in FIG. In addition, in the case of a character input operation, the time during which the TV program screen of the channel is interrupted can be shortened. Note that the time from when the key is pressed in step S14 until the channel is actually switched is longer than that in the flowchart shown in FIG.

  Here, in the above embodiment, the character is input as the character processing immediately, but the information of the television program may be further taken in as text. Hereinafter, a description will be given with reference to FIGS. Here, FIG. 7 is a flowchart showing another example of the processing operation of the portable electronic device.

  First, the main control unit 22 immediately starts character processing as step S60. Note that the start of character processing is the same as the processing in step S38 in FIGS. 4 and 6 described above. When the main control unit 22 starts character processing immediately at step S60, the main control unit 22 scans the one-segment reception screen as step S62. In other words, the television broadcast image received and displayed on the screen is analyzed, and image information is acquired. Various image analysis software can be used for this scan (analysis). As the image analysis software, image analysis software capable of extracting at least character information included in the image is used.

  After scanning the image in step S62, the main control unit 22 determines whether there is character information in the scanned image in step S64. If the main control unit 22 determines in step S64 that there is no character information (No), the main control unit 22 proceeds to step S68. If the main control unit 22 determines that character information is present (Yes) at step S64, the main control unit 22 immediately displays the scanned character information on the character editor (immediate character input screen) as step S66. That is, the character information extracted from the television screen is set as the input character and immediately displayed on the character input screen.

  If the character information is displayed in step S66 or if it is determined No in step S64, the main control unit 22 determines whether there is a character input in step S68. That is, it is determined whether a character is input by a key operation by the operator. If it is determined in step S68 that there is a character input (Yes), the main control unit 22 displays the input character as step S70. That is, the character input by the operator's key operation is immediately displayed on the character input screen. When the main control unit 22 displays the character input in step S70, the main control unit 22 proceeds to step S72.

  If it is determined in step S68 that there is no character input (No), or if the processing in step S70 is completed, the main control unit 22 immediately terminates (completes) the character processing termination instruction, that is, character input as step S72. It is determined whether or not this is detected. If the main control unit 22 determines in step S72 that an end instruction has not been detected (No), the main control unit 22 proceeds to step S68 and determines again whether there is a character input. In this manner, the main control unit 22 repeats the character input process and the input character display process until an end instruction is detected.

  If the main control unit 22 determines in step S72 that an end instruction has been detected (Yes), in step S74, the main control unit 22 determines whether there is an input character string. That is, it is determined whether there is a character string input by the operator other than the character string extracted from the image in step S64 and step S66. If it is determined in step S74 that there is a character string (Yes), the main control unit 22 displays a selection menu item as step S76. That is, a menu for processing a character string input by character input is displayed. Specifically, menus such as “Register to memo”, “Register schedule”, and “Search” are displayed. After displaying the menu in step S76, the main control unit 22 detects menu selection as step S78. That is, the main control unit 22 detects a menu selection instruction input by the operator.

  If the menu is selected in step S78, or if it is determined in step S74 that there is no character string (No), the main control unit 22 executes the menu as step S80. The main control unit 22 executes the selected menu when the menu is selected in step S78, and executes the preset menu when it is determined that there is no character string (No) in step S74. To do. For example, if it is determined in step S74 that there is no character string (No), schedule registration may be performed.

  Here, "Register to memo" is a process of registering a character string as a memo, "Schedule registration" is a process of registering a character string as a schedule, and "Search" is a process of registering a character string as a search condition. As a process of performing a search. In the case of “schedule registration”, if the date and time is entered in the character string, the character string without the date and time may be registered as the schedule for that date and time. In order to execute the menu, only the processing screen for the menu is displayed, and thereafter, the menu may be further operated by the operator. After executing the menu in step S80, the main control unit 22 ends the process.

  Hereinafter, the change of the display unit will be described with reference to FIG. Here, FIG. 8 is an explanatory diagram for explaining the operation of the portable electronic device. First, when 1Seg is activated, the television broadcast of the set channel is displayed on the display unit 32 as shown in the upper left in FIG. Thereafter, as shown in the upper right in FIG. 8, the character processing is started immediately in a state where an image including text is displayed on the screen of the display unit 32 as a television broadcast. Specifically, “8” of the operation key 3 is input (pressed) twice. When “8” of the operation key 3 is input (pressed) twice, as shown in the lower left of FIG. 8, a character string obtained by scanning the screen, in this embodiment, “ticket reservation OO-XXX” The character editor (input screen) is activated immediately after the is entered. In addition, “Y”, which is a character corresponding to the two input of “8” of the operation key 3, is also input.

  After that, when the operator further operates the operation key to input a character string, the character string “Yukai Band Ticket Reservation XX-XXX” is input as shown in the lower right of FIG. Become. The input character string is subjected to processing such as “registration to memo”, “schedule registration”, and “search” based on the operation of the operator.

  In this way, the television broadcast screen is scanned, the character information displayed on the screen is acquired, and the acquired character information is immediately used as a character input character string. You can note what you are watching on the broadcast. Thereby, an operator's operation can be made easier.

  In addition, when the character string for character input is only character information taken from a television broadcast screen, the operability can be further improved by executing the set menu. For example, text information captured from a television broadcast screen can be continuously stored as a memo with a simple operation.

  Here, in the above embodiment, the character information is acquired by scanning the screen, but the method of acquiring the character information from the television broadcast is not limited to this. Hereinafter, another example will be described with reference to FIG. Here, FIG. 9 is a flowchart showing another example of the processing operation of the portable electronic device. Note that the flowchart shown in FIG. 9 includes steps for performing the same processing as the flowchart shown in FIG. Therefore, in the following, steps that perform the same processing as the steps shown in FIG. 7 are denoted by the same step numbers, detailed description thereof will be omitted, and processing specific to the flowchart shown in FIG. I will explain it.

  First, the main control unit 22 immediately starts character processing as step S60. When the main control unit 22 starts character processing immediately in step S60, the main control unit 22 scans the one-segment received data in step S82. That is, the data received as one-segment broadcasting (television broadcasting) is scanned to obtain the configuration of the received data. Here, in one-segment broadcasting, in addition to image data and audio data of television broadcasting, program information data describing program information and the like is transmitted and received as received data.

  After scanning the received data in step S82, the main control unit 22 determines whether there is character information in the scanned data in step S84. If the main control unit 22 determines in step S84 that there is no character information (No), the main control unit 22 proceeds to step S68. If the main control unit 22 determines that character information is present (Yes) in step S84, the main control unit 22 immediately displays the scanned character information on the character editor (immediate character input screen) as step S86. That is, the character information included in the data received as the program information data is set as the input character and immediately displayed on the character input screen.

  If the character information is displayed in step S86 or if it is determined No in step S84, the main control unit 22 determines whether there is a character input in step S68. That is, it is determined whether a character is input by a key operation by the operator. Here, the processing from step S68 to step S80 is the same processing as the processing of the flowchart shown in FIG.

  In this way, in the case of a television broadcast, by acquiring character information from the transmitted program information data, the content being viewed on the television broadcast without input by the operator, as in the case of scanning the screen Can be noted. Thereby, an operator's operation can be made easier. Since data can be directly captured, character information can be acquired more accurately than when scanning an image.

  Next, another example of the processing operation of the portable electronic device will be described with reference to FIGS. 10 and 11. Here, FIG. 10 is a flowchart showing another example of the processing operation of the portable electronic device, and FIG. 11 is an explanatory diagram for explaining the operation of the portable electronic device.

  When the one-seg activation instruction is input by the operator, the main control unit 22 performs the one-seg activation process and starts the output of the television broadcast as step S102. After starting the output of the television broadcast in step S102, the main control unit 22 immediately starts character processing as step S106 after detecting a character processing start operation as step S104. Here, the character processing start operation is an operation in which the operation key is pressed a certain number of times within a certain time, as described above.

  When the main control unit 22 starts character processing immediately in step S106, the main control unit 22 performs character input processing in step S108. That is, the operation of the operation key 3 by the operator is detected, and a character string input by the operation of the operation key 3 is created and displayed. After the character input process is performed in step S108, the main control unit 22 searches for a table of confirmed character strings in step S112 when a character confirmation operation is detected in step S110. That is, when the main control unit 22 detects a character string confirmation operation input by the operator in step S110, the main control unit 22 uses the table to detect a processing operation corresponding to the confirmed character string in step S112. Here, the table stores the relationship between the input character string and the corresponding processing operation. In the table, for example, the character string “Rokuga” is associated with the processing operation “Recording of TV broadcast”, and the character string “Onyo” is associated with the processing operation “volume control”. Also, “mail” is associated with the processing operation “launch mail function”.

  After searching the table based on the confirmed character string in step S112, the main control unit 22 determines whether there is a corresponding function in step S114. That is, the main control unit 22 determines whether the processing operation (corresponding function) performed by the main control unit 22 has been detected from the confirmed character string and the table. If the main control unit 22 determines in step S114 that there is no corresponding function (No), that is, it cannot determine the processing operation from the confirmed character string, the main control unit 22 proceeds to step S108 and performs the character input process again.

  If the main control unit 22 determines in step S114 that the corresponding function is present (Yes), the main control unit 22 performs the corresponding function activation process in step S116. After performing the corresponding function activation process in step S116, the main control unit 22 immediately performs a character process end process in step S118, immediately ends the character process, and ends the process.

  Hereinafter, changes in the display unit will be described with reference to FIG. First, when 1Seg is activated, the television broadcast of the set channel is displayed on the display unit 32 as shown on the left side in FIG. Thereafter, the character processing is started immediately, and as shown in the center of FIG. 11, “Rokuga” is input as a character string by the operator, and the character confirmation operation is performed. As described above, when a character confirmation operation is performed, a television broadcast recording process is detected as a corresponding function corresponding to “Rokuga”, and as shown on the right side in FIG. A message “Recording has started” is displayed on the display unit 32.

  As described above, by detecting the processing operation based on the input character string and executing the processing operation, various operations can be performed without performing a troublesome menu operation while viewing the television broadcast. be able to.

  In the above embodiment, when the corresponding process cannot be detected from the character string, the character input process is performed. However, the present invention is not limited to this, and when the corresponding process cannot be detected, the input character string is stored as a memo. You may do it.

  In the above-described embodiment, the operator inputs characters and instructions by operating the operation keys. However, the input device is not limited to this. For example, a touch panel may be used as the input device. Hereinafter, the case where a touch panel is used as an input device will be described with reference to FIGS. 12 and 13. Here, FIG. 12 is a flowchart showing another example of the processing operation of the portable electronic device, and FIG. 13 is an explanatory diagram for explaining the operation of the portable electronic device. In the present embodiment, the touch panel is disposed on the back surface of the main display 2M, and detects that the operator touches the main display 2M as an input. Further, the flowchart shown in FIG. 12 is a process in a state where a one-segment process is executed and a television broadcast is being output.

  First, when the main control unit 22 detects a touch panel operation in step S120, that is, detects that the touch panel is operated by the operator, the main control unit 22 performs character recognition processing in step S122. That is, the main control unit 22 detects the locus of input to the touch panel, that is, the movement of the touch position (contact point), and performs processing for recognizing the locus as a character.

  After performing the character recognition process in step S122, the main control unit 22 determines in step S124 whether the operator input is a recognizable character as a result of the process in step S122. If the main control unit 22 determines that the character is not a recognizable character in step S124 (No), that is, the input detected as an operation in step S120 cannot be recognized as a character, the main control unit 22 performs other processing in step S126. As other processes, various processes can be performed. For example, if it is determined that the input is to a button displayed on the display, a process corresponding to the input button may be performed. Further, the output of the television broadcast may be continued without activating any function. The main control unit 22 ends the process after performing another process in step S126.

  If the main control unit 22 determines that the character is a recognizable character in step S124 (Yes), that is, a character is input from the touch panel, the main control unit 22 immediately starts character processing as step S128, and recognizes it in step S122 as step S130. Recognize character display processing. Thereafter, the main control unit 22 performs character processing immediately as step S132, and ends the processing when the character processing is completed immediately. Note that the immediate character processing is processing for detecting a character input from the touch panel, creating a character string, and displaying the character string. In addition, the character string created immediately after the character processing is stored as a memo or schedule.

  Next, changes in the display unit will be described with reference to FIG. First, when 1Seg is activated, a television broadcast of a set channel is displayed on the display unit 32 as shown on the left side in FIG. After that, as shown in the center of FIG. 13, the operator draws the locus of “ku” with a finger on the main display 2M (touch panel). As described above, when the operator operates the touch panel and the input is detected by the main control unit 22, the character processing is started immediately. As shown on the right side in FIG. Appears. Thereafter, when the operator writes characters on the main display 2M (touch panel), the written characters are displayed in a column for displaying input characters. At this time, a television broadcast screen is also displayed.

  In this way, even when a touch panel is used as an input device, when a character input is detected, the character input function is activated and the input character is displayed. Characters can be input by drawing. Thus, the operator can input characters without temporarily stopping the television broadcast, and can input characters with a simple operation. In addition, character input can be started while viewing a television broadcast.

  In the present embodiment, the character processing is started as soon as a character is detected. However, the present invention is not limited to this, and as in the flowcharts shown in FIGS. 4 and 6, the input is a channel change instruction. It may be determined whether there is character input or character input, and character processing may be started immediately after detecting character input. For example, if the input character is a number, the subsequent input is waited, and if there is an input exceeding the number of digits of the channel, the character processing may be started immediately. Thereby, the channel change and the character input can be executed without any special operation.

  In the above-described embodiment, each example has been described individually for simplification of explanation, but it goes without saying that the processing of each embodiment may be combined. For example, if the character processing is activated immediately in the processing of FIG. 4, the processing of FIG. 7 and FIG. 9 may be performed. 7 and 9 are preferably selectable by setting. Thereby, when extraction of a character string is unnecessary from a screen or data, it can be made not to extract.

As described above, the input device, a character input device及beauty input method according to the present invention, apparatus having a function of displaying a television broadcast and a character input function, it is useful to be used in the process.
