  Next, in step S <b> 406, the main control unit 123 outputs a control command to the light emission control unit 108 based on the light emission pattern read from the memory unit 109.

  Next, in step S407, the light emission control unit 108 controls the light emission unit 107 to emit light based on a control command from the main control unit 123, and emits or turns off each light emitting element with the light emission pattern read from the memory unit 109. .

  The above is the flowchart showing the basic operation until the detected information is displayed on the key in the first embodiment of the present invention.

  Next, an example relating to the display of information including numbers will be described with reference to the display of channel numbers at the time of television reception. FIG. 5 is a flowchart showing an operation of displaying the channel number on the input unit 106 when receiving television.

  First, in step S501, when a user operates a key for selecting a television receiving function or selecting an arbitrary broadcasting station, a request for selecting a television receiving function or a request for selecting a broadcasting station is accepted. At this time, the channel number requested to be selected is stored in the memory unit 109.

  Next, in step S <b> 502, the control unit 101 displays a control command relating to reception of a television broadcast signal to the reception unit 102, and a control command for decoding the received signal into a video signal to the decoding unit 103. Control signals for displaying video signals are respectively output to, to receive television signals and display television images.

  Next, in step S503, the main control unit 123 reads the channel number currently being received from the memory unit 109.

  Next, in step S <b> 504, the main control unit 123 extracts a predetermined number from the channel numbers read from the memory unit 109.

  Next, in step S505, the main control unit 123 selects a key displaying a number corresponding to the number extracted in step S504 from the input unit 106, and selects a light emission pattern for causing the key to emit light from the memory unit 109. read out. For example, if the number is “7”, only the light emitting element paired with the key displaying “7” emits light in order to selectively emit the key displaying “7” in the numeric keypad. Such a light emission pattern is read out.

  Next, in step S <b> 506, the main control unit 123 outputs a light emission command to the light emission control unit 108 according to the light emission pattern read from the memory unit 109.

  Next, in step S507, the light emission control unit 108 controls the light emission unit 107 to emit light based on a control command from the main control unit 123, and emits or turns off each light emitting element with the light emission pattern read from the memory unit 109. . Thus, the light emitting unit 107 emits light with the light emission pattern read from the memory unit 109.

  Next, in step S508, the main control unit 123 confirms whether a new channel selection request has been made by the user. When there is a new channel selection request, a series of processes is terminated, and the process returns to the start and starts a new process. If there is no new channel selection request, the process proceeds to step S509.

  Next, in step S509, it is determined whether the displayed number is the first digit of the channel number. If it is determined that it is the first place, the process returns to step S503 to display from the highest place. At this time, display delimiters may be indicated by turning off all keys or emitting light. If it is determined that it is not the first place, the process proceeds to step S510.

  Next, in step S510, the number to be displayed next is lowered by one from the currently displayed position, and after a predetermined waiting time, the process returns to step S504. Thus, for example, if the channel number is “157”, the key “1” indicating hundreds, the key “5” indicating tenths, and the key “7” indicating ones are fixed. Then, light is emitted in sequence, and the fact that the channel number being received is 157 is displayed using the input unit 106. If the channel number is one digit, the channel number may be continuously displayed. The above-described processing is repeated until the channel number changes due to a new channel selection request.

  In this way, in the example of channel number display at the time of TV reception, since the key displaying the number corresponding to the channel number being received is lit, it can be seen at a glance which channel is being received. Become.

  As described above, according to the first embodiment, a key displaying a number corresponding to a number included in the information detected by the information detection unit or a number representing the information is selected from the input unit, and the key is selected. Since the number is displayed on the input unit by selectively emitting light, the display amount of information can be increased without enlarging the main body and the display unit of the mobile phone.

  In the first embodiment, an example in which numerical values of a plurality of digits are displayed in order from the upper digit is shown. However, this is only one embodiment, and for example, “1” is displayed to display “12”. All the keys included in the numbers may be emitted and displayed at the same time, for example, the “2” key and the “2” key may be emitted simultaneously. In this display, for example, when there are the same numbers in different places such as “122”, the “1” key continues to emit light, and the “2” key repeats light emission and extinction. Only the keys corresponding to can be repeatedly turned on and off to indicate that the numbers overlap.

  Further, in the present embodiment, it may be configured such that only the input-acceptable key of the input unit 106 is caused to emit light. FIG. 6 is a diagram showing an example of display on the input unit 106. In FIG. 6, when the TV reception function is selected, only the channels assigned to the keys “1”, “2”, “3”, “5”, “8”, and “9” can be received. Is shown by making only those keys emit light. When switching the channel, the user can view a receivable channel simply by operating one of the light-emitting keys, eliminating the need to search for a receivable channel by operating the key. It can be omitted. In this way, when only the key corresponding to the receivable channel number is emitted when the television reception function is selected, the user can know at a glance which channel is the receivable channel. The load on the user can be reduced. Further, it may be configured not to accept an input of a key that does not emit light. In this way, for example, even if a key that does not emit light is mistakenly operated, the key input is not accepted, so there is no possibility of switching to a channel that cannot be received, and the load on the user is further reduced. Can do. This configuration is not limited to the channel display in the TV reception function, but is applied to a case where a plurality of selection targets are displayed at the same time, for example, when a music playback function is provided and a selectable song number is displayed. can do.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS.

  The second embodiment is different from the first embodiment in that the light emitting elements of the light emitting unit 107 are configured to emit light in a plurality of light emission colors independently. Other than that, the configuration is the same as the example shown in the first embodiment, and the same operation is performed.

  Here, as in the first embodiment, a description will be given by taking as an example a display in the case where television reception is performed in a mobile phone with a television reception function.

  FIG. 7A is a diagram showing the mobile phone 100 in the second embodiment, and FIG. 7B is a diagram summarizing the radio wave state of the channels assigned to each key and the emission color of each key. It is. In the second embodiment, the light emitting unit 107 that is paired with each key is configured by a light emitting element that can emit light by switching between three colors of green, yellow, and red. Therefore, the light emitting unit 107 has four states as light emission states, which are light emission in three colors and light extinction. Therefore, in order to perform grouping according to the radio wave condition, four groups from 3 with a good radio wave condition to 0 with a bad radio wave condition are created and assigned to any of the four groups according to the radio wave condition of each channel.

  In FIG. 7B, the channels assigned to the keys “1”, “2”, and “8” are assigned to the group of the radio wave status 3, and the channels assigned to the keys “5” and “9” are set to the radio wave status. In the group 2, the channel assigned to the “3” key is assigned to the radio wave state 1 group, and the channel assigned to the “6” key is assigned to the radio wave state 0 group. “-” Indicates that there is no original channel setting.

  When the channel number is displayed on the key, the key is emitted by changing the emission color depending on the group. That is, the keys “1”, “2”, “8” that are groups of the radio wave state 3 are green, the keys “5”, “9” that are the groups of the radio wave state 2 are yellow, Each group “3” key is illuminated in red. Keys with no radio wave status 0 and no channel setting are turned off. As described above, when the channel number is displayed on the key, the number of groups is determined based on the emission color of the light emitting unit 107, the channels are grouped based on the radio wave condition, and the emission color is changed depending on the group. Thus, the user can know at a glance which channel can be received with a good radio wave condition.

  FIG. 8 is a block diagram of the mobile phone 100 shown in FIG. 7, which is configured by adding a scanning unit 112 to the block diagram shown in FIG. In FIG. 8, the scanning unit 112 controls the receiving unit 102 and the decoding unit 103 in accordance with a command from the main control unit 123 to sequentially switch the receiving channel, and simultaneously detects the radio wave state of each channel, and at the same time, each key of the input unit 106. The channels are allocated to the memory unit 109 and the information is stored in the memory unit 109 (hereinafter, this series of processing is referred to as scanning).

  This scanning operation will be described. FIG. 9 is a flowchart showing the scanning operation. As shown in FIG. 9, first, in step S <b> 901, a scan operation command is output from the main control unit 123 to the scan unit 112 in response to a scan request from the user.

  Next, in step S902, the scanning unit 112 controls the receiving unit 102 and the decoding unit 103 to perform a channel selection operation for the first channel.

  Next, in step S903, the main control unit 123 acquires information related to the radio wave state of the reception channel from the reception unit 102, and allocates the reception channel to a predetermined group according to the radio wave state. This operation will be described later.

  Next, in step S904, the main control unit 123 stores the reception channel and the group to which the reception channel is allocated in the memory unit 109.

  Next, in step S905, it is determined whether the channel currently being received is the last channel in the channel selection range. If it is determined that it is not the last channel, the process proceeds to step S906.

  Next, in step S906, the scanning unit 112 controls the receiving unit 102 and the decoding unit 103, selects the next channel, and returns to step S903.

  If it is determined in step S905 that the currently selected channel is the last channel, the process ends.

  The above is the description of the scan operation in the second embodiment.

  Next, an operation of controlling the light emission of the light emitting unit 107 based on the radio wave state of the reception channel will be described. FIG. 10 is a flowchart showing the operation of detecting the radio wave state of the reception channel and controlling the light emission unit 107 to emit light according to the second embodiment.

  As shown in FIG. 10, first, in step S1001, the scanning unit 112 controls the receiving unit 102 and the decoding unit 103 according to a command from the main control unit 123, receives a television broadcast signal, and determines the radio wave state in the receiving channel. To detect. Then, based on the detected radio wave condition, the reception channel is assigned to one of four groups from 3 with a good radio wave condition to 0 with a bad radio wave condition.

  Next, in step S1002, the information detection unit 122 confirms whether the group to which the reception channel is allocated is a group with the radio wave state 1 or higher. If it is determined that the radio wave state is 1 or more, the process proceeds to step S1003.

  Next, in step S1003, the main control unit 123 reads the light emission pattern from the memory unit 109 based on the channel number of the reception channel and the group to which the reception channel is allocated.

  Next, in step S1004, the main control unit 123 outputs a control command to the light emission control unit 108 based on the read light emission pattern.

  Next, in step S <b> 1005, the light emitting unit 107 emits or turns off the light emitting elements of the light emitting unit 107 based on a control command from the light emission control unit 108, and emits the light emitting unit 107 with the light emission pattern read from the memory unit 109. To finish the process.

  If it is determined in step S1002 that the radio wave state is 0, the flow ends.

  As described above, according to the second embodiment, for example, the number of groups is determined based on the emission color of the light emitting unit 107, the radio wave state of each channel is detected by the scanning operation, and each channel is set to the radio wave state. By grouping based on the group, and changing the emission color of each channel according to the group and displaying it on the key at the same time, the user can know at a glance which channel can be received in a good radio wave condition. As a result, when switching channels, it is possible to easily select only channels with good radio wave conditions. In particular, in the case of a mobile phone with a TV reception function shown in this embodiment, the radio wave state changes depending on the movement of the user. It is possible to reduce the burden on the user by switching the channel and searching for a channel with a good radio wave condition.

  In the present embodiment, an example has been shown in which the emission color is changed according to the radio wave state of the reception channel and the channel number is displayed as a key. However, other than this, for example, a genre added to a signal in television broadcasting The identification code is discriminated by the information detection unit 122, the discrimination output is given to the main control unit 123, the emission color is divided according to the genre of the program by controlling the light emission control unit 108, etc. Whether it is TV reception or not, the remaining capacity of the battery or memory card is represented by a number, and the emission color is changed depending on whether the remaining capacity is sufficient. The same effect can be obtained when the numbers displayed on the input unit 106 can be assigned to a plurality of groups, such as changing the emission color depending on the length.

  Further, when a multi-digit number is displayed on the input unit 106 by light emission, the light emission color may be changed depending on the position. In addition, when the same numbers overlap in different places, the keys of the overlapped numbers may be switched so that the light emission color is changed at regular intervals so that the numbers overlap.

  Further, the same effect can be obtained even when the display is performed by changing the light emission luminance instead of the light emission color. For example, if the light emission luminance is switched between three levels of strong, medium, and weak, it can be configured in the same manner as the structure for switching light emission with the three light emission colors described above. Further, the same effect can be obtained when the display is performed by changing the emission pattern instead of the emission color. For example, if there are three types of light emission patterns, the light emission pattern A in which the time ratio of continuous light emission and light emission and extinction is 2: 1 and the light emission pattern B in which the time ratio of light emission and extinction is 1: 2, the above-mentioned. It is possible to configure in the same manner as the configuration in which the emission is switched between the three emission colors.

In FIG. 18, a GPS signal receiving antenna 131 receives a GPS (Global Positioning System) signal, and a detection unit 132 detects latitude and longitude information of the current location from the received GPS signal. Based on the detected current location information and the like, the map information processing unit 133 reads the current location surrounding map information from the memory unit 109, displays the current location surrounding map on the display unit 104, or calculates the distance to the destination. . Other than this, the configuration is the same as the example shown in the first embodiment, and the same operation is performed.

  As shown in FIG. 18, in the fifth embodiment of the present invention, the mobile phone 100 is configured to have a current location detection function using a GPS signal, and provides route guidance from the current location to the destination desired by the user ( (Hereinafter abbreviated as navigation).

  Next, the navigation operation will be described with reference to FIG. FIG. 19 is a flowchart showing the navigation operation of the mobile phone 100 according to the fifth embodiment of the present invention.

  First, in step S1901, the detection unit 132 detects the latitude and longitude of the current location from the GPS signal received by the GPS signal receiving antenna 131 as current location information.

  In step S1902, the map information processing unit 133 reads map information from the memory unit 109 based on the detected current location information, and displays the map information on the display unit 104 as a current location surrounding map. At this time, a map around the current location is displayed on the display unit 104 so that the vicinity of the center of the display unit 104 is the current location. Moreover, you may comprise so that a user can set arbitrarily the reduced scale of the present location surrounding map, and in that case, based on the set reduced scale, a present location surrounding map is displayed. The map information may be stored in advance in the memory unit 109, or the current location information is transmitted by using the communication function of the mobile phone 100 and a map information providing service or the like that is generally performed. The structure which receives may be sufficient.

  Next, in step S1903, the user operates an arbitrary key of the input unit 106 to input a destination. The input destination information is temporarily stored in the memory unit 109.

  In step S 1904, the map information processing unit 133 compares the destination information stored in the memory unit 109 with the current location information detected by the detection unit 132. If it is determined that the current location is the same as the destination, the process ends. If it is determined that the current location is not the destination, proceed to the next step.

  Next, in step S1905, the map information processing unit 133 compares the current location information and the destination information, and calculates the direction and distance from the current location to the destination.

  Next, in step S1906, the main control unit 123 selects a key to be emitted from the input unit 106 based on the direction and distance from the current location to the destination calculated in step S1905, and selectively emits the key. The light emission pattern to be read is read from the memory unit 109.

  Thereafter, the process returns to step S1901 to detect the current location. Note that the destination once input in step S1903 is held until a new destination is input or the above-described series of processing ends. Then, a series of processing is repeated until it is determined that the current location is equal to the destination or until the user is forcibly terminated.

  The above is the flowchart showing the navigation operation in the fifth embodiment of the present invention.

  FIG. 20 is a diagram showing an example in which the destination direction is displayed on the input unit 106 of the mobile phone 100 according to the fifth embodiment of the present invention. In FIG. 20, a map around the current location is displayed on the display unit 104 with the vicinity of the center of the display unit 104 as the current location. The destination input in advance by the user is on the left side of the display unit 104. A key “5” is arranged in the center of the keys arranged in 5 rows and 3 columns of the input unit 106. Accordingly, assuming that the key “5” is the current location and the traveling direction from the current location to the destination on the map displayed on the display unit 104 is the left direction, “4” located to the left of the “5” key. ”Key.

  That is, in the fifth embodiment, a map around the current location is displayed so that the vicinity of the center of the display unit 104 is the current location, and the keys arranged in the center of the keys arranged in a matrix of the input unit 106 are used as the current location. By making a key appear in the same direction as the direction from the current location to the destination on the map around the current location displayed on the display unit 104, the traveling direction to the destination is easily displayed to the user.

  As described above, in the fifth embodiment of the present invention, the mobile phone 100 is configured to have a current location detection function using a GPS signal, and progresses when navigating from the current location to the destination. The direction of travel can be displayed in an easy-to-understand manner by emitting a key corresponding to the direction.

  When there is no current location near the center of the current location map displayed on the display unit 104, the displayed current location map is associated with the keys arranged on the matrix, and the key corresponding to the location of the destination is emitted. You may comprise so that it may do.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described with reference to FIGS.

  The sixth embodiment is different from the fifth embodiment in that it indicates the traveling direction to the destination depending on whether or not the destination is included on the map around the current location displayed on the display unit 104. This is a point where the light emission of the key of the input unit 106 is changed. As described above, the sixth embodiment is different from the fifth embodiment only in the display form, and other block configurations, flowcharts, and the like are the same as those in the fifth embodiment.

  FIGS. 21A and 21B are diagrams showing an example in which the destination direction is displayed on the input unit 106 of the mobile phone 100 according to the sixth embodiment of the present invention. In FIG. 21A, a map around the current location is displayed at a scale at which the current location and the destination are displayed at the same time. Similarly to the example shown in FIG. 20, a key corresponding to the traveling direction is emitted to return to the destination. The direction of travel is displayed. On the other hand, FIG. 21 (b) shows a map around the current location in which the vicinity of the current location is enlarged, and the destination is outside the range of the displayed map around the current location. Therefore, the destination is not displayed on the display unit 104. Accordingly, the light emission of the key for displaying the traveling direction is stopped.

  That is, in the example shown in FIG. 21, when the destination is no longer displayed on the map due to the enlarged display of the map around the current location displayed on the display unit 104, the light emission of the key for displaying the traveling direction is displayed. It is configured to stop. With such a configuration, whether or not the destination is displayed on the map around the current location displayed on the display unit 104 only by looking at whether or not the key for displaying the traveling direction is lit or not, It can be seen at a glance whether the destination is outside the range of the current location surrounding map displayed on the display unit 104. Therefore, it is possible to see at a glance how much the current location map displayed on the display unit 104 can be reduced to display the current location and the destination at a glance, and it is easy to set a guideline for determining the scale of the current location map. .

  FIGS. 22A and 22B are diagrams showing another example in which the destination direction is displayed on the input unit 106 of the mobile phone 100 according to the sixth embodiment of the present invention. In FIG. 22A, a map around the current location is displayed at a scale at which the current location and the destination are displayed at the same time. Similar to the example shown in FIG. 20, a key corresponding to the traveling direction is emitted to return to the destination. The direction of travel is displayed. At this time, the emission color of the key is yellow. On the other hand, in FIG. 22B, a map around the current location is displayed in which the vicinity of the current location is enlarged, and the destination is outside the range of the current location surrounding map displayed on the display unit 104. Therefore, the destination is not displayed on the display unit 104. Therefore, the key for displaying the direction of travel to the destination is caused to emit light in red, which is a light emission color different from the light emission color of the key in FIG.

  That is, in the example shown in FIG. 22, when the destination is displayed on the map around the current location displayed on the display unit 104 and when the destination is outside the range of the current location map, the display unit 104 has the destination. The light emission color of the key for displaying the traveling direction is changed depending on whether it is not displayed. With such a configuration, whether the destination is displayed on the map around the current location displayed on the display unit 104 or only by looking at the light emission color of the key for displaying the traveling direction, or the display unit 104 You can immediately see if there is a destination outside the range of the current location map displayed on. Therefore, it becomes possible to see at a glance how far the current location map displayed on the display unit 104 can be reduced to display the current location and the destination at the same time, and it is easy to set a guideline for determining the scale of the current location map. . Further, since the key indicating the direction of travel always emits light even if the light emission colors are different, the travel to the destination is performed regardless of whether the destination is displayed on the map around the current location displayed on the display unit 104. You can see the direction at a glance.

  As described above, in the sixth embodiment of the present invention, when there is a destination on the current location surrounding map displayed on the display unit 104 and when the destination is outside the range of the displayed current location surrounding map. In some cases, it is possible to change the light emission of the key for indicating the direction of travel to the destination, thereby making it easier to set a guideline for determining the scale of the current location map. In addition, it is possible to recognize at a glance the traveling direction to the destination regardless of whether the destination is displayed on the map around the current location.

  The emission colors of the keys such as yellow and red shown in FIG. 22 are merely examples of the embodiment, and any combination of emission colors may be used as long as the emission colors are different. Further, it may be a combination of light emission with different light emission luminances or different flashing patterns.

(Seventh embodiment)
Next, a seventh embodiment of the present invention will be described with reference to FIG.

  The seventh embodiment is different from the fifth embodiment in that the number of keys to emit light is changed according to the distance from the current location to the destination in order to indicate the traveling direction to the destination. is there. As described above, the seventh embodiment is different from the fifth embodiment only in the display form, and other block configurations, flowcharts, and the like are the same as those in the fifth embodiment.

  FIGS. 23A and 23B are diagrams showing an example in which the destination direction is displayed on the input unit 106 of the mobile phone 100 according to the seventh embodiment of the present invention. In FIG. 23 (a), a map around the current location is displayed at a scale at which the current location and the destination are displayed at the same time, and as in the example shown in FIG. The direction of travel to is displayed. At this time, there is a distance (not shown) of about 5 km from the current location to the destination, and therefore the number of keys that are lit to display the direction of travel to the destination is one. On the other hand, FIG. 23B is an enlarged map of the current location around FIG. 23A, and is approaching a distance of about 200 m (not shown) to the destination by movement. Therefore, the number of keys that emit light in order to display the direction of travel to the destination is three.
