Field of the Invention The present invention relates to a portable telephone terminal, and more particularly, to a portable telephone terminal having an enhanced incoming call notification function. 2. Description of the Related Art In recent years, portable telephone terminals having various functions (hereinafter simply referred to as portable terminals) have been developed. Above all, a ring tone to be sounded at the time of an incoming call is not a simple buzzer sound but a melody sound (ring melody) combining a plurality of scales has come to be used. In addition, a function has been developed in which a different incoming melody is output for each telephone number of a caller so that a person who has received an incoming call can be identified by sound. When a call is received, the caller ID is displayed on the mobile terminal, so if you look at the mobile terminal, it is possible to identify who received the call before answering.How to make the incoming melody different with the caller ID, see the mobile terminal This is extremely convenient because it is possible to identify who has received the call before.  However, it may not be possible to distinguish a ringing melody in a place with a large amount of noise. In such a case, it is not possible to identify the incoming melody. To solve this problem, Japanese Patent Application Laid-Open No. 2001-2001 discloses a technology in which a backlight light emitting diode such as an operation key is turned on in accordance with the scale of a ringing melody so that it can be visually determined from whom. No. 53839 discloses a “mobile radio terminal device”.  Japanese Patent Application Laid-Open No. 2001-532001
The technique disclosed in Japanese Patent No. 839 can identify a caller even in a place with a lot of noise, but the on / off control of the light emitting diode such that the light emitting diode corresponding to the scale of the incoming melody is turned on and the other is off. Therefore, a display that is visually monotonous and rich in color with consideration for entertainment has been required.  An object of the present invention is to provide a portable telephone terminal device capable of identifying a caller by an incoming melody.
It is an object of the present invention to provide a mobile phone terminal device that can notify an incoming call by displaying a colorful backlight. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a ring tone melody output means for outputting a ring tone melody when a call is received, and a scale for outputting the tone melody during the ring tone output. A scale detecting means to be taken out, a light emitting means provided at a plurality of positions which can be seen by the user, each of which can emit light in a plurality of colors, and a light emitting means in which position emits light in which color for each scale of a ringtone melody A table for setting whether the scale is detected by the scale detecting means at the time of outputting a ringtone melody, the light emitting means set for the scale set in the table is set in the color set for the scale. A mobile phone terminal device comprising: a control unit that controls light emission by the mobile phone terminal. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a mobile phone terminal device of the present invention. The radio signal input from the antenna 10 passes through the transmission / reception switching unit 11 and
, And demodulated by the demodulation unit 13 to become a digital signal. This digital signal is decoded by the codec 16. If the decoded signal is a control signal such as a calling signal, the control unit 20 receives the signal.
7 is output. The audio signal amplified by the audio unit 17 is output from the speaker 18. On the other hand, the sound from the microphone 19 is adjusted in level by the audio unit 17, encoded by the codec 16, converted into a radio signal by the modulation unit 15, amplified by the transmission unit 14, and output from the antenna 10 via the transmission / reception switching unit 11. . The transmission / reception switching unit 11 outputs a signal input from the antenna 10 to the reception unit 12 and outputs a signal input from the transmission unit 14 from the antenna 10. The control unit 20 is connected to the codec 16 and, via a control bus 29, a memory 21, a nonvolatile memory 22, an operation unit 23, a display unit 24, an operation unit backlight 26, a display unit backlight 27, A sounder 28 is connected. The memory 21 is used for temporarily storing data, flags, and the like necessary for the operation of the program. The non-volatile memory 22 is a memory that does not lose its contents even when the power supply unit 25 that supplies power to the portable terminal is turned off. The non-volatile memory 22 includes telephone directory telephone number data and ring melody data for driving the sounder 28 when receiving a call. The backlight ON / OFF memory 30 and the backlight / color table 31 used for storing data required by the program. The operation unit 23 is composed of various keys, such as numeric keys for inputting dial numbers and the like, function keys, arrow keys, setting keys, end keys, and the like.
It is used to input various operations as a portable terminal to the control unit 20, and has a backlight ON / OFF characteristic of the present invention.
It is also used for writing to the OFF memory 30 and the backlight / color table 31. The operation unit backlight 26 is
The keys of the operation unit 23 are illuminated from the back, and can emit light in various colors for each key. A simple configuration can be realized by installing a plurality of light-emitting elements such as color light-emitting diodes that emit the required colors behind each key. The display unit 24 displays the input from the operation unit 23, the strength of the received radio wave, the current state of the portable terminal, the incoming call history, and the like. Display backlight 27
Is for illuminating the display unit 24 from the back. The display unit backlight 27 in FIG. 2 is an example in which the entire display unit 24 emits light in a selected color. Of course, the display unit 24 is divided,
Similar to the emission of a plurality of keys, it is also possible to emit light in a partially different color. The sounder 28 outputs an incoming melody for notifying the user of the incoming call from the speaker 18 at the time of the incoming call. The control unit 20 understands the control signal input from the codec 16, performs terminal control corresponding to the control signal, and outputs a call control signal and the like to the codec 16 and displays it on the display unit 24. In addition, it understands the input from the operation unit 23, displays it on the display unit 24, controls the portable terminal, and also performs the backlight control of the present invention. Hereinafter, the control of the present invention will be described in detail based on a backlight control flow shown in FIG. First, the control unit 20 checks whether there is an incoming call (N in STEP 101).
O loop). If there is an incoming call (YE in STEP 101)
S), the control unit 20 performs incoming call control as a portable terminal (STEP 102). At the beginning of the incoming call control (STEP 102), an incoming call is displayed on the display unit 24, the sounder 28 is driven by the incoming melody data in the nonvolatile memory 22, the incoming melody is output from the speaker 18, and the user receives the incoming call. It is to inform. Next, the control unit 20 turns on / off the backlight of the nonvolatile memory 22.
The user accesses the memory 30 to see if the user has selected to perform backlight control (STEP 103).
If the user has selected to perform backlight control, the backlight ON / OFF memory 30 is "1", and if not, "0". If backlight control is not performed (STEP 1
03, NO), the process ends only with the normal incoming call control without performing the backlight control of the present invention. When performing backlight control (STEP
If YES at 103, it is checked whether or not the transmission of the incoming melody has been completed (STEP 104). This indicates whether the control unit 20 has stopped driving the sounder 28 when the user responds to the incoming call or when the caller stops calling. If the transmission of the incoming melody has been completed (YES in STEP 104), the backlight of the key that has been emitting light is turned off (turned off) (STEP 11).
0), this control ends. If the incoming melody is being transmitted (NO in STEP 104), a scale for driving sounder 28 is extracted (STEP 105). This sounder 28
The method of extracting the scale for driving the sound depends on how the control unit 20 drives the sounder 28. Here, the ringing melody is stored in the
Information on notes, rests, such as mi, fa, s, la, shi, and de, and length information such as whether they are two- or four-notes, two- or four-rests, etc. Octave information or the like. The control unit 20 detects the note and rest information of the incoming melody and, based on the detected note and rest information, determines the time scale of the note length as the drive scale (drive frequency).
Shall be driven. Since the control unit 20 knows the scale currently transmitted from the sounder 28 to the speaker 18, it is easy to extract the scale (including the rest). When the scale driving the sounder 28 is extracted (STEP 105), the backlight / color table 31 is accessed based on the scale information, and the key and color information corresponding to the scale are obtained. Extract (STEP10
6). FIG. 2 shows a configuration example of the backlight / color table 31. If the extracted scale is “do” of the basic scale, the octave information is “1” and the key “0” is entered from the field of the scale “do”,
The color information “Blue” is extracted. If “do” is octave higher, “do” of octave information “2” is accessed, and key “4” and color information “Red” are extracted. The scale on which the control unit 20 drives the sounder 28 is not necessarily “do” but may be “do #”, which is a semitone higher. However, in the backlight / color table 31 of FIG. Access is excluded.
As the key information of the backlight / color table 31, only examples of the numeric keys 0, 1, 2, 3, 4, etc. are shown, but the operation unit 23 such as #, *, on-hook key, power key, etc.
It is also possible to make other keys provided on the display unit emit light, or the display unit 24 may emit light. In these cases, an on-hook key, a power key, and characters and symbols indicating the display unit 24 are written in the key fields. Since there are more types of scales than types of keys, one key corresponds to a plurality of scales. In FIG. 2, the key "2"
Corresponds to both the scales "mi" and "fa", and the key "0" corresponds to the scale "do" of the octave "1" and the scale "do" of the octave "3". In the backlight / color table 31 of FIG. 2, there is always key information corresponding to the scale, but there may be a scale in which no key information is written. If no key information is written, it means that no key emits light at that scale. Here, no key information is written, so that no key emits light at that scale. However, an ON / OFF column corresponding to the scale is provided, and if that column is turned off, no key emits light. You may. The control unit 20 accesses the backlight / color table 31 and extracts key information corresponding to the scale driving the sounder 28. If there is no corresponding key information (NO in STEP 107), the control unit 20 emits light. The backlight of the pressed key is turned off (turned off) (STEP 108), and the process returns to STEP (STEP 104) as to whether the incoming melody has ended. If there is key information corresponding to the scale driving the sounder 28 (YES in STEP 107), the backlight of the light emitting key is turned off, the backlight of the extracted key is turned on (lit) in the extracted color, and the incoming call is received. The process returns to STEP (STEP 104) as to whether the melody has been completed. According to the above control, the operation unit 23 corresponds to the scale of the incoming melody.
, And the display unit 24 can emit colorful light. Next, a backlight ON / OFF memory 3 for indicating whether or not the user performs a backlight control for causing keys and the like to emit color light in response to the incoming melody, and how to cause the keys and the like to emit light in color. The setting method of the backlight / color table 31 shown will be described based on the backlight setting flow of FIG. The control unit 20 first checks whether the user sets the backlight (STE).
NO loop at P201). To set the backlight, the user inputs a combination of a function key and a number from the keys of the operation unit 23 of the mobile terminal. For example, when the function key and the numeric key 3 are input (STEP 2
01 (YES), the control unit 20 displays an ON / OFF selection screen of the backlight ON / OFF memory 30 on the display unit 24. The user looks at the screen and inputs whether to perform backlight control. The user's input method is performed by selecting one of the displayed ON and OFF with the arrow keys and pressing the setting key. When the user selects the backlight display of the ring tone (STEP 20)
2 is YES), the control unit 20 turns the backlight ON / OFF.
The memory 30 is turned on (STEP 203). When the user does not select the backlight display of the incoming melody (NO in STEP 202), the control unit 20 turns off the backlight ON / OFF memory 30 (STEP 202).
204). Next, the control section 20 displays the contents of the backlight / color table 31 on the display section 24 to make the state changeable by the user (STEP 205). The display unit 24 displays the contents of the backlight / color table 31 shown in FIG. If the user does not change the setting contents of the backlight / color table 31 (NO in STEP 205), the user presses the end key, and the flow ends. When the user changes the setting contents of the backlight / color table 31, (STE
(YES in P205), and selects a key field or a color field to be changed displayed on the display unit 24 (STEP 206).
Change the value in that column to the desired key and color (STEP 2
07). After changing one column (STEP 20)
7) To change another key or color (ST
(YES in EP205), and select a column to be changed again (ST
EP 206), and change the field to a desired value (STE
P207). The choice of keys or colors to change in this way,
The change is repeated (STEP 205, 206, 207 loop). When the change is completed (NO in STEP205),
Exit with exit key. Next, an example of a method for changing the backlight / color table 31 will be described. It is assumed that the contents of FIG. 2 are displayed on the display unit 24. First, the user selects a part to be changed (STEP 206). That is, the cursor is moved to a portion to be changed using the horizontal arrow key or the vertical arrow key. For example, in FIG. 2, when changing the key "0" corresponding to the scale "do" to the key "5", move the cursor over "0" displayed in the key column corresponding to the scale "do". Move. When the setting key is pressed, the field can be changed. When the vertical arrow key is pressed in this state, the displayed number changes to 0, 1, 2, and 3. When the setting key is pressed again when 5 is displayed, 5 is set. Of course, the display may be changed to 5 by pressing the numeric key 5 instead of selecting with the vertical arrow key, and the setting may be made with the setting key. Changing the color corresponding to the scale can be performed in the same manner. That is, a color field corresponding to the scale "do" is selected with the arrow keys. When changing the color “Blue” corresponding to the scale “do” in FIG. 2 to “Red”,
When the cursor is moved to “Blue” and the setting key is pressed, a color field corresponding to the scale “C” is selected. And
When you press the vertical arrow key, the display changes to Blue, Green,
It changes with Yellow and Red. Pressing the set key when the desired color is displayed will select that color.
Thus, the user changes the contents of the backlight / color table 31 displayed on the display unit 24. Each time the display on the display unit 24 is changed, the control unit 20 changes the memory contents of the backlight / color table 31 of the nonvolatile memory 22. It is also possible not to set the key corresponding to the scale. For example, when the key “0” corresponding to the scale “do” in FIG. 2 is selected and the delete key is pressed, 0 disappears, and nothing is displayed in the key column corresponding to the scale “do”. In this case, the key of the operation unit 23 and the backlight of the display unit 24 are not turned on even if the musical scale “do” is in the ring tone melody. Further, in the example of the backlight / color table 31 shown in FIG. 2, a case where one key is associated with one musical scale is shown. However, since the backlight of one key is necessarily lit at one musical scale, Instead, a plurality of keys may correspond to one musical scale. The display of colors is also shown in FIG. 2 as Blue, Green, Yellow, and Red.
And an example in which four types of colors can be selected has been described, but the number is not limited to four. By providing three types of light emitting elements, blue, green and red, which are the three primary colors of light, for each key as a backlight and controlling the luminous intensity of each light emitting element, light emission of an arbitrary color becomes possible. Arbitrary color selection is also feasible. According to the present invention, the following effects can be obtained. (1) The keys and the display unit of the portable terminal emit light in a plurality of colors corresponding to the scale of the ringtone melody, so that it is visually beautiful and the entertainment is enhanced. (2) Since the keys and colors emitted in the ring tone can be changed according to the user's preference, further entertainment can be obtained. (3) If the incoming melody is changed in accordance with the caller, it is easy to determine who is calling from the key light emission pattern even in a noisy place. (4) Even if the volume is lowered or the output of the incoming melody from the speaker is stopped in a place where the sending of the incoming melody is prohibited, it is possible to know who is calling from the light emission pattern of the key.
