Description

  The present invention relates to a key backlight control method, a control method, and a control program therefor, and more particularly to a key identification method using multicolor lighting.

  With the downsizing of portable electronic devices, the operation key area is inevitably narrowed. In particular, a cellular phone or the like has a backlight function in the key operation unit in preparation for use in the dark such as a key operation error or at night.

  Currently, in the key backlight emission method used in portable electronic devices such as mobile phones, all keys emit the same color when the key backlight is lit.

  Further, the key operation is performed by visually confirming the characters written on the key top and operating the desired key. However, depending on the user with weak visual acuity and the use environment, an operation error due to misrecognition may occur.

  In order to improve the operability of such key operations for the user, a key backlight is individually provided for each operation key, and a control terminal for controlling on / off of each backlight is independently provided. For example, Japanese Patent Application Laid-Open No. 11-53086 discloses a technique for turning on only the backlight corresponding to an operationally valid key in the operation mode and turning off the backlight corresponding to the operation invalid key in the operation mode. (First prior art).

  The first prior art includes a control unit (microcomputer), a matrix operation key, a backlight corresponding to each of the numeric keys of the matrix operation key, the * key, and the # key, and a backlight for individually turning on / off the backlight. A backlight drive circuit comprising transistor switches, an output terminal for outputting control signals for individually turning on / off the backlight, and an input terminal for constantly scanning a state where the operation key is pressed and taking it into the control unit In the state where the backlight is turned off for the first time, all the backlights are turned on when the user presses any key, and the second and subsequent key inputs in a series of key operations are in that state. Only the back light of the key that is valid in is turned on, and the invalid key is pressed in that state Can output an alarm sound, when there is no certain time key input to turn off the backlight.

  However, this prior art 1 has a problem that the LEDs used for the backlight are monochromatic and cannot emit light in different colors for the numeric key, * key, and # key.

  In addition to the first prior art, the key operation signal is identified and the key operation identification signal indicating the key operation performed by the user is decoded to determine the key that will be effective next. For example, Japanese Patent Laid-Open No. 2001-34398 discloses a technique for causing a user to recognize the next operation key by causing an LED disposed for a determined key to emit light (second conventional technique).

  In the second prior art, only the yellow LED is provided for the numeric keys used for inputting numbers and characters (registered names), and the red, green, and yellow LEDs are provided for a plurality of keys other than the numeric keys. For example, when registering a phonebook by classifying a large number of phone numbers, the registered name input mode is activated first, all numeric keys used for entering numbers and characters (registered name input) are yellow, and the registered name is entered. Confirm the * key is green, and the scroll key for converting the registered name to Kanji is lit in red. When the registered name is confirmed, the phone number entry mode is entered and the numeric key for entering the phone number is entered in yellow. Confirm the phone number * The green key is lit in green, and when the phone number is confirmed, the group number entry mode is entered and the grouping key for entering the group number is classified. The number of number key that corresponds to the number of over-flop is intended to recognize yellow, an invalid key operation valid key and operation respectively emit light in green a * key to determine the number of groups that have been input from the user.

  In addition, when a predetermined time is clocked, all keys are irregularly illuminated when a call is received from a specific party, thereby providing entertainment.

  However, in this second prior art, although the numeric keys and keys other than the numeric keys emit light in different colors, all the emission colors are single colors (red, green, yellow), and the user sets a desired emission color. I can't.

  In addition, since all numeric keys emit light in a single yellow color, the numeric keys cannot be set to different colors individually.

  Further, there is a description that when a predetermined time is clocked, all keys are caused to emit light irregularly when a call is received from a specific party, but a specific method is not disclosed.

  Even in this irregular light emission, there is no designation of the light emission color. That is, it is unclear in which color the decision key, function key, call opening type, clear key, redial key, * key, and # key other than the numeric keys are emitted.

  In addition, since all numeric keys emit light in a single yellow color, the numeric keys cannot be set to different colors individually.

  Further, there is a description that when a predetermined time is clocked, all keys are caused to emit light irregularly when a call is received from a specific party, but a specific method is not disclosed.

  The backlight 4 includes three-color LEDs 4-1 to 4-12 corresponding to each key of the operation unit 2. The wireless unit 7 transmits and receives wireless signals when communicating with other wireless devices or networks.

  The color control unit 5 includes color control drivers 5-1 to 5-12 corresponding to the three-color LEDs 4-1 to 4-12, and individually controls the three-color LEDs 4-1 to 4-12. The backlight of each key of the operation unit 2 is controlled.

  In FIG. 1, the three-color LEDs 4-1 to 4-12 and the color control drivers 5-1 to 5-12 correspond to numeric input keys, * keys, and # keys, respectively. Also, although three color LEDs and a color control driver are respectively provided, only the key backlight for the numeric input key, * key, and # key is described.

  The storage unit 6 includes a light emission color control table 6-1 for controlling individual light emission colors of the three-color LEDs 4-1 to 4-12 of the backlight 4 shown in FIG. 7, and previously registers color data for each light emission color. Keep it.

  The color control drivers 5-1 to 5-12 for driving the three-color LEDs 4-1 to 4-12 use a PWM control type three-color LED control driver (for example, New Japan Radio NJU6060), and the emission color is a maximum of 32768 colors. Can be set theoretically.

  The storage unit 6 includes a key-corresponding light emission color setting memory 6-2 shown in FIG. 8, and the user can set an arbitrary light emission color for each key based on the light emission color control table 6-1. Here, a case where different emission colors are individually set for the numeric input keys (key numbers 1 to 10), * key (key number 11), and # key (key number 12) is shown as an example.

  That is, red for key number 1 (numeric key 1), green for key number 2 (numeric key 2), blue for key number 3 (numeric key 3), purple for key number 4 (numeric key 4), Key number 5 (numeric key 5) is yellow, key number 6 (numeric key 6) is white, key number 7 (numeric key 7) is orange, key number 8 (numeric key 8) is brown, key number 9 (numeric key 9) is registered in light blue, key number 10 (numeric key 0) is reddish purple, key number 11 (* key) is yellowish green, and key number 12 (# key) is registered in blue purple. Yes.

  Further, as shown in FIG. 9, the storage unit 6 includes a function-corresponding light emission color control table 6-3, and the light emission color and color data of valid / invalid keys corresponding to each function are stored in advance. The color data can be arbitrarily set by the user based on the emission color control table 6-1.

  The operation unit 2 is disposed on the key backlight 4 so as to irradiate each key.

  Next, referring to FIG. 2 together with FIG. 1, the processing for setting the emission color of the key backlight will be described.

  The user selects a light emission color setting mode by pressing a predetermined key of the operation unit 2 in order to set a desired key backlight light emission color for each key (step S101 in FIG. 2). An arbitrary key of the input keys (numeric key, * key, # key), for example, numeric key 1 is pressed (S102).

  The control unit 1 receives the key information of the numeric key pressed from the operation unit 2 and determines the key number (S103). If the determination result in step S103 is not key number 1 (numeric key 1), the process proceeds to step S107. If it is key number 1 (numeric key 1), the light emission color of the pressed key is designated on the display unit 3. A color designation menu (FIG. 3) for displaying is displayed (S104).

  In this luminescent color specification menu, for example, red, green, blue, purple, yellow, white, orange, brown, light blue, yellow green, magenta, red key, Twelve blue-violet colors are displayed.

  The user moves the cursor to select a light emission color for the numeric key 1, for example, red, from the color designation menu displayed on the display unit 3, and presses the enter key. (S105).

  The control unit 1 includes an emission color (red) identification code selected and confirmed by the user from the emission color control table 6-1 of the storage unit 6, and an emission color control signal of the key backlight (three-color LED). The color data is read, and the light emission color (red) and the color data (red) are stored in the key-corresponding light emission color setting memory 6-2 of the storage unit 6 corresponding to the key number 1 of the numeric key designated by the user (S106). .

  If the determination result in step S103 is not the numeric key 1, it is determined whether the key number is 2 (numeric key 2) (S107). If the determination result is the numeric key 2, the color designation menu is displayed on the display unit 3. Is displayed (S108).

  The user moves the cursor to select a light emission color for the numeric key 2, for example, green, from the color designation menu displayed on the display unit 3, and presses the enter key. (S109).

  The control unit 1 selects the light emission color (green) selected and confirmed by the user from the light emission color control table 6-1 of the storage unit 6 and green color data which is color control data of the key backlight (three-color LED). And the light emission color (green) and the color data (green) are stored in the key corresponding light emission color setting memory 6-2 of the storage unit 6 corresponding to the key number 2 of the numeric key designated by the user (S106).

  When the determination result in step S107 is not the numeric key 2, the key number 3 (numeric key 3) to the key number 10 (numeric key 0) are sequentially determined. Similarly, for the numeric key 3, for example, blue, numeric key 4 Is purple for numeric key 5, white for numeric key 6, orange for numeric key 7, brown for numeric key 8, and light blue for numeric key 9 For the numeric key 0, the color data corresponding to magenta is stored in the key corresponding emission color setting memory 6-2 of the storage unit 6 in correspondence with each key number.

  Further, for the key number 11 (* key), for example, yellow-green and color data (yellow-green) are stored in the key corresponding emission color setting memory 6-2 of the storage unit 6 corresponding to the key number 11 (step S110). To steps S112, S106), for example, blue-violet and color data (blue-purple) are stored in the key corresponding emission color setting memory 6-2 of the storage unit 6 for the key number 12 (# key) (S313-S115, S106).

  Similarly, any color can be set for various function keys (not shown).

  In this way, a desired emission color is designated for each key of the operation unit 2 and the emission color and color data are stored in correspondence with each key number in the key-related emission color setting memory 6-2 of the storage unit 6. The key identification and key operation are facilitated by reading the I description data of the emission color of each key from the key corresponding emission color setting memory 6-2 and turning on the key backlight at the time of incoming / outgoing calls, mail creation, and the like.

  Next, the key backlight lighting control process will be described with reference to FIG. 4 together with FIG. When an event occurs (step S201 in FIG. 4), the control unit 1 determines whether or not it is an incoming call (S202).

  If the determination result in step S202 is an incoming call, each key number and the color data that is the emission color control signal corresponding to each key number are read from the key-corresponding emission color setting memory 6-2 (FIG. 8) of the storage unit 6. (S203), the data is transferred to the color control driver 5-1 to 5-12 arranged corresponding to each key in the color control unit 5 (S204). The color control drivers 5-1 to 5-12 temporarily store the transferred color data from the control unit 1.

  The control unit 1 monitors the transfer of the key numbers and the color data to all the color control drivers 5-1 to 5-12, and when the transfer end is detected (S205), all the color control drivers 5-1 to 5-12. Is instructed to turn on the key backlight (S206).

  When receiving the key backlight lighting instruction from the control unit 1, the color control drivers 5-1 to 5-12 light all the backlights with different colors and irradiate the operation keys (S207).

  If the determination result in step S202 is not an incoming call, the control unit 1 detects the input key information (S208), and determines whether the key information is a request for starting a predetermined application function (for example, a game) (209). .

  If the determination result in step S209 is not an activation request for the predetermined application function, it is recognized that the operation is a call operation or a mail mode, the process proceeds to step S203, and the processes in steps S203 to S207 are executed. In other words, all the keys are turned on with a different emission color in the color data registered in the key-corresponding emission color setting memory 6-2.

  As shown in FIG. 5, the keys of the operation unit 2 at the time of incoming call, outgoing call, and mail mode are red for the numeric key 1, green for the numeric key 2, blue for the numeric key 3, and purple for the numeric key 4. The numeric key 5 is yellow, the numeric key 6 is white, the numeric key 7 is orange, the numeric key 8 is brown, the numeric key 9 is light blue, the numeric key 0 is magenta, the * key is yellow-green, and the # key is blue-purple Each is irradiated.

  If the determination result in step S209 is a request for starting a predetermined application function, a specified function, for example, an application program for a game is started (S210). Here, the predetermined application function refers to, for example, a game function, a stopwatch function, a calculator function, an alarm / alarm function, a barcode reading function, a camera imaging function, and the like. Here, a case where a game function is executed will be described as an example.

  When the application program for the game function (game) is activated, the control unit 1 reads the key number and valid / invalid key of the function A which is the game function from the function corresponding emission color control table 6-3 (FIG. 9) of the storage unit 6. The code and the emission color control information corresponding to each key are read (S211), and based on the valid / invalid code, it is determined whether the key numbers 1 to 12 are valid keys or invalid keys (S212).

  As shown in FIG. 9, in the function-corresponding emission color control table 6-3, a key necessary for (uses) the function operation for each function is a valid key, and a key unnecessary for the function operation is invalid key. In order to turn on the backlight with different colors, color data which is a light emission color control signal corresponding to each key number is registered.

  In the function-corresponding emission color control table, valid keys necessary for operating function A, function B to function N and invalid keys unnecessary for operation are classified by the signs of “1” and “0”. Color data of different emission colors is set for the invalid key.

  According to FIG. 9, in the case of function A (game function), key numbers 2 (numeric key 2), key numbers 4, 5, 6 (numeric keys 4, 5, 6), Key number 8 (numeric key 8) is set, and red color data is set for each valid key.

  In addition, key number 1 (numeric key 1), key number 3 (numeric key 3), key number 7 (numeric key 7), and key numbers 9 to 12 (numeric key 0, * key, # key) are set as invalid keys. In addition, yellow color data is set for each invalid key. That is, the valid key is red, the invalid key is yellow, and the backlight is lit.

  In function B, key number 1 (numeric key 1), key number 4 (numeric key 4), key number 7 (numeric key 7), and key number 11 (* key) are set as necessary valid keys. Green color data is set for the key.

  As invalid keys, key number 2 (numeric key 2), key number 3 (numeric key 3), key number 5 (numeric key 5), key number 6 (numeric key 6), key numbers 8, 9, 10 (numeric) Keys 8, 9, 10) and key number 12 (# key) are set, and blue color data is set for each invalid key. That is, the valid key is green and the invalid key is blue, and the backlight is lit.

  Similarly, in function N, key numbers 3, 6, 9, 12 (numeric keys 3, 6, 9, # key) are lit in orange as valid keys, and key numbers 1, 2, 4, 5, 7 are used as invalid keys. , 8, 10, 11 (numeric keys 1, 2, 4, 5, 7, 8, 0, * key) are lit in yellow-green.

  The control unit 1 controls the color control driver corresponding to the valid key determined in step S212 (color control drivers 5-2 and 5-4 to 5 corresponding to the valid keys 2, 4, 5, 6, and 8 according to FIG. 9). The red color data is transferred to (-6, 5-8) (S213).

  If the determination result in step S212 is an invalid key, the color control driver corresponding to the invalid key (according to FIG. 9, the color control driver 5-1 corresponding to the invalid keys 1, 3, 7, 9, 10, 11, 12). 5-3, 5-7, 5-9 to 5-12), the yellow color data is transferred (S214).

  The control unit 1 monitors the transfer of the color data of all the keys to all the color control drivers 5-1 to 5-12, and detects the end of the transfer (S215), and sends it to all the color control drivers 5-1 to 5-12. The key backlight is instructed to be turned on (S216).

  When the color control drivers 5-1 to 5-12 receive an instruction to turn on the key backlight from the control unit 1, the valid key and the invalid key are displayed in different colors (the valid key is red and the invalid key is yellow). Turn on (S217).

  Thus, when the application function is, for example, a game, the keys of the operation unit 2 are numeric keys 2, 4, 5, 6, and 8 that are valid keys as shown in FIG. 6, and numeric keys that are invalid keys. 1, 3, 7, 9, 0, and * and # keys are illuminated in yellow, respectively.

Next, a second embodiment will be described.
In the second embodiment, the key backlight emits light in any different light emission color or any same color (common color), and controls the brightness to be different for each key, thereby facilitating user key operations. Is.

  The light emission luminance control drivers 8-1 to 8-12 need only be able to individually control the light emission luminances of the three-color LEDs 4-1 to 4-12 of the backlight 4, and are not limited in their configurations. Then, the same PWM control type three-color LED multi-color control driver as that in the first embodiment is used.

  The storage unit 6 includes a light emission luminance control table 6-4 for controlling the light emission luminance of the three-color LEDs 4-1 to 4-12 shown in FIG. 14, and the light emission luminance control table includes the three-color LEDs 4-1 to 4- Luminance data for controlling the emission luminance corresponding to each of a plurality of (e.g., 12) emission colors as 12 emission colors is registered in advance. As the luminance data corresponding to each emission color, different luminance intensity data is set corresponding to each key number.

  The luminance intensity data for each key number can be arbitrarily set by the user, but here, the luminance is set from high luminance to low luminance in the order of the key numbers.

  That is, as shown in FIG. 14, this luminance data recognizes a predetermined luminance range, for example, a numeric key, * key, and # key in order to set different brightness for each of the three color LEDs 4-1 to 4-12. The possible luminance range is divided into 12 levels of luminance intensity data in a predetermined step, and the allocation of the luminance intensity data for each of the three color LEDs is maximum in the order of the key operation of each numeric key, * key, # key of the operation unit 2 The luminance is set from the luminance to the minimum luminance for each step.

  According to FIG. 14, the highest luminance (luminance intensity data 1) to the lowest luminance (luminance intensity data 12) are stored in the order of key operations, corresponding to each emission color.

  The storage unit 6 includes a key-corresponding light emission luminance setting memory 6-5 shown in FIG. 15, and the user can arbitrarily set different luminance data for each key number based on the light emission luminance control table.

  According to FIG. 15, the common emission color (red) is set for the key numbers 1 to 12, the maximum luminance is set for the key number 1, and the key numbers 2 to 12 are sequentially set in predetermined steps. Luminance data is set so that the luminance decreases. Therefore, the key backlight is turned on in a predetermined light emission color (common color, for example, red) in the order of the number keys 1 to 9, number key 0, * key, and # key of the operation unit 2 and lighted.

  Note that the user can arbitrarily set the light emission colors common to the three-color LEDs 4-1 to 4-12, and the luminance data setting order for each key number can be arbitrarily set according to the key operation order of the user. it can.

  Furthermore, the storage unit 6 includes a function-corresponding light emission luminance control table 6-6 shown in FIG. 16, and the light emission color and luminance data of the valid / invalid key corresponding to each function are stored in advance. The brightness data can be arbitrarily set by the user based on the light emission brightness control table.

  The operation unit 2 is disposed on the key backlight 4 so as to irradiate each key.

  Next, referring to FIG. 11 together with FIG. The luminance setting process for the light emission color will be described.

  When the user selects a luminance setting mode by pressing a predetermined key on the operation unit 2 to set the desired luminance of the key backlight emission color for each key (step S301 in FIG. 11), the display unit 3 displays FIG. Is displayed (S302).

  This color specification menu allows you to select any one of 12 colors as a common color in addition to 12 colors of red, green, blue, purple, yellow, white, orange, brown, light blue, yellow green, red purple, and bluish purple “Common” items are displayed.

  After the user selects “common” displayed on the display unit 3 with the cursor (S303), the cursor is moved to select an arbitrary emission color, for example, “red” (S304), and a predetermined key operation (for example, The red key is designated as a common emission color (red) for the input keys (numeric key, * key, # key) of the operation unit 2. When a different emission color is designated for the input key (numeric key, * key, # key), the desired emission color is designated without selecting the “common” item.

  Subsequently, when the user presses any key of the input keys (numeric key, * key, # key) of the operation unit 2, for example, the numeric key 1 (S305), the control unit 1 determines the key operation order of the user. Therefore, “1” is recorded in a counter (not shown) (S306).

  The control unit 1 determines the operation order based on the count value of the counter (S307). When the operation order is not “1”, the process proceeds to step S310 to determine the operation order, and when the operation order is “2”. In step S308, if the operation order is not "2", the operation orders "3" to "12" are similarly determined (S312 and S314).

  If the determination result in step S307 is the operation order “1”, the key number is determined based on the key information pressed by the user (S308). If the key number is 1, the light emission luminance control table 6-4 is used. “Luminance intensity data 1 (maximum value)” of “key pressing order 1” is read out from the emission color, for example, “red” identification code and luminance data corresponding to red, and stored in correspondence with key number 1. The data is stored in the key-corresponding light emission luminance setting memory 6-5 of the unit 6 (S309).

  If the determination result in step S308 is not key number 1, it is determined whether it is key number 2 (numeric key 2) (S311). If numeric key 2 and the operation order is “1”, light emission is performed. From the luminance control table 6-4, the “luminance intensity data 1 (maximum value)” of “key pressing order 1” is read out from the luminance data corresponding to the emission color, for example, “red”, and the luminance data corresponding to red, and the key Corresponding to the number 2, it is stored in the key-corresponding light emission luminance setting memory 6-5 of the storage unit 6 (S309).

  When the determination result in step S311 is the numeric key 2 and the operation order is “2”, the emission color, for example, the “red” color identification code and the luminance data corresponding to red from the emission luminance control table 6-4. "Luminance intensity data 2 (<maximum value)" of "Key pressing order 2" is read out and stored in the key corresponding light emission luminance setting memory 6-5 of the storage unit 6 in correspondence with the key number 2 (S309). .

  Similarly, if the determination result in step S311 is not key number 2, key number 3 (numeric key 3) to key number 10 (numeric key 0) are sequentially determined, and the emission color, for example, from the emission luminance control table 6-4, for example, The luminance intensity data corresponding to the operation order determined in Steps S307, S310 to S312, and S314 is read out from the “red” color identification code and the luminance data corresponding to red, and the storage unit corresponding to the determined key number 6 is stored in the key corresponding light emission luminance setting memory 6-5 (S309).

  In this way, the light emission color of the key can be set to any color, and the intensity of the light emission luminance with respect to the key backlight of the three-color LEDs 4-1 to 4-12 corresponding to the user's key operation order and the key number. Can be set arbitrarily. In the key-corresponding light emission brightness setting memory 6-4 shown in FIG. 15, the user enters key number 1 (numeric key 1) to key number 10 (numeric key 0), key number 11 (* key), key number 12 ( Luminance data is set when operating in the order of # key).

  In this case, the key backlight is turned on with a red emission color with low luminance in the order of the numeric keys (1 to 9, 0), * key, and # key.

  Next, the light emission luminance control processing of the key backlight will be described with reference to FIG. When an event occurs (step S401 in FIG. 13), the control unit 1 determines whether or not it is an incoming call (S402).

  If the determination result in step S402 is an incoming call, the common emission color (red) and all the keys (numeric keys 1 to 9,. (0, * key, # key) The luminance intensity data corresponding to the number is sequentially read (S403) and transferred to the light emission luminance control drivers 8-1 to 8-12 arranged for the respective keys of the light emission luminance control unit 8. (S404).

  When the control unit 1 monitors the transfer of the common emission color and the luminance data to the emission luminance control drivers 8-1 to 8-12 and detects the end of the transfer (S405), all the emission luminance control drivers 8-1 to 8-1-8 are detected. The key backlight is instructed to -12 (S406).

  When the light emission brightness control drivers 8-1 to 8-12 receive an instruction to turn on the key backlight from the control unit 1, all the keys have the designated common light emission color (red) and the individual keys based on the brightness intensity data. The key backlight is turned on with different brightness (S407). As a result, each key of the operation unit 2 is irradiated with red light with different brightness.

  If the determination result in step S402 is not an incoming call, the control unit 1 detects the input key information (S408), and determines whether the key information is a request for starting a predetermined application function (for example, a game) (409). .

  If the determination result in step S409 is not an activation request for the predetermined application function, it is recognized that the operation is a call operation or a mail mode, the process proceeds to step S403, and the processes in steps S403 to S407 are executed. In other words, all keys are lit in the key backlight with a different luminance for each key in the emission color (common color) registered in advance in the key-corresponding emission luminance setting memory 6-4.

  If the determination result in step S409 is a request for starting a predetermined application function, a specified function, for example, an application program for a game is started (S410). Here, the predetermined application function refers to, for example, a game function, a stopwatch function, a calculator function, an alarm / alarm function, a barcode reading function, a camera imaging function, and the like. Here, a case where a game function is executed will be described as an example.

  The storage unit 6 includes a function-corresponding light emission luminance control table 6-6 shown in FIG. 16, and a key that is necessary (used) for the function operation for each function is a valid key, and a key that is unnecessary (not used) for the function operation. Is used as an invalid key, and luminance data, which is a light emission luminance control signal, is registered in correspondence with each key number in order to turn on the key backlight with different luminance in a common light emission color.

  According to the function-corresponding light emission luminance control table 6-6 shown in FIG. 16, valid keys necessary for operating the functions A, B to N and invalid keys unnecessary for the operation are set to “1” and “0”. Different brightness data are set for the valid key and the invalid key.

  In the case of function A (game function), key numbers 2 (numeric keys 2), key numbers 4, 5, 6 (numeric keys 4, 5, 6), key numbers 8 (numeric keys) 8) is set, red is set for each valid key, and brightness data 1 which is the maximum brightness value is set.

  In addition, key number 1 (numeric key 1), key number 3 (numeric key 3), key number 7 (numeric key 7), and key numbers 9 to 12 (numeric key 0, * key, # key) are set as invalid keys. Then, red is set for each invalid key, and luminance data 6 that is a luminance value half of the maximum luminance value is set. The brightness data for the invalid key can be arbitrarily set by the user, but here, the brightness value is set to half the maximum brightness value.

  That is, the valid key is illuminated with a high-luminance red color, and the invalid key is illuminated with a red color with a lower luminance than the valid key. Therefore, the user can distinguish the valid key and the invalid key based on the difference in luminance. The brightness data (brightness value) for the valid key and the invalid key can be arbitrarily set by the user.

  Similarly, function B and function N are also more effective depending on the brightness of the key backlight by setting an arbitrary emission color and arbitrary luminance data in advance for the valid key and unnecessary invalid key required for each function. Keys and invalid keys can be distinguished.

  When the application of the game function is activated in step S410, the control unit 1 reads the key number, valid / invalid key code, from the function-corresponding light emission luminance control table (function A in FIG. 16) registered in advance in the storage unit 6. Luminance data, which is a light emission luminance control signal corresponding to each key number, is read (S411), and it is determined whether the key numbers 1 to 12 are valid keys or invalid keys based on the valid / invalid key codes (S412).

  The light emission luminance control drivers 8-2, 8-4, 8-5, 8-6, 8 of the light emission luminance control unit 8 corresponding to the key numbers 2, 4, 5, 6, 8 determined to be valid keys in step S412. “Luminance data 1” is transferred to −8 (S413).

  In addition, the light emission luminance control drivers 8-1, 8-3, 8-7, 8- of the light emission luminance control unit 8 corresponding to the key numbers 1, 3, 7, 9, 10 to 12 determined as invalid keys in step S412. “Luminance data 6” is transferred to 9, 8-10 to 8-12 (S414).

  The control unit 1 monitors the transfer of luminance data to the light emission luminance control drivers 8-1 to 8-12, and detects the end of the transfer of luminance data (S415), all the light emission luminance control drivers 8-1 to 8- 12 is instructed to turn on the key backlight (S416).

  When the light emission luminance control drivers 8-1 to 8-12 receive a key backlight lighting instruction from the control unit 1, the effective key turns on the backlight with high luminance red, and the invalid key turns on the backlight with low luminance red ( S417).

  Although description of the case where the function designation in step S409 is the function B and the function N is omitted, the key backlight can be turned on with the effective key and the invalid key in an arbitrary emission color and with an arbitrary luminance.

Next, a third embodiment will be described.
In the third embodiment, the key backlight emits light in any different light emission color or any same color (common color) and is controlled at different timing (light emission pattern) for each key, thereby allowing the user to perform key operations. To make it easier.

  FIG. 17 is a main configuration diagram of the mobile phone according to the third embodiment, FIG. 18 is a flowchart of the key backlight emission color setting process according to the third embodiment, and FIG. 19 is an outgoing / incoming call according to the third embodiment. FIG. 20 is a diagram showing a configuration example of a light emission pattern control table in the third embodiment, and FIG. 21 is a diagram showing the configuration of the third embodiment. FIG. 22 is a diagram illustrating a configuration example of a key-corresponding light emission pattern setting memory in FIG. 22, and FIG. 22 is a diagram illustrating a configuration example of a light emission pattern control table corresponding to an application function in the third embodiment.

  As shown in FIG. 17, the mobile phone to which the present invention is applied includes a light emission pattern control unit 9 that controls the key backlight 4, and the light emission pattern control unit 9 includes the three-color LEDs 4-1 to 4-12 of the backlight 4. Are formed by light emission pattern control drivers 9-1 to 9-12. In addition, since it is the same structure as 1st Embodiment except the light emission pattern control drivers 9-1 to 9-12, description is abbreviate | omitted.

  The light emission pattern control drivers 9-1 to 9-12 need only be capable of individually controlling the light emission timings of the three-color LEDs 4-1 to 4-12 of the backlight 4, and the configuration thereof is not limited here. Then, the same PWM control type three-color LED multi-color control driver as that in the first embodiment is used.

  The storage unit 6 includes a light emission pattern control table 6-7 for controlling the light emission patterns of the three-color LEDs 4-1 to 4-12 shown in FIG. As the 12 emission colors, emission color identification codes and emission pattern data for controlling the emission timing are registered in advance corresponding to each of a plurality of (e.g., 12) emission colors. As the light emission pattern corresponding to each light emission color, different light emission pattern data is set for each key number. The user can arbitrarily set the light emission pattern data for this key number.

  In order to set different timings for each of the three-color LEDs 4-1 to 4-12, the light emission pattern data has different frequency division ratios in predetermined steps that can recognize, for example, numeric keys, * keys, and # keys. The light emission pattern data is divided into 12 types of light emission pattern data, and the light emission pattern data is assigned to each three-color LED in different division ratios for each step in the order of operation of the numeric keys, * key, and # key of the operation unit 2. Is set.

  This light emission pattern data can be easily generated by dividing a predetermined signal, for example, a clock pulse.

  According to FIG. 20, different light emission pattern data is registered in the key operation order for each light emission color. This light emission pattern data is composed of pulse signals having different frequency division ratios in a predetermined period, and pulse signals having a small frequency division ratio are registered in order from a pulse signal having a large frequency division ratio in the order of user key operations.

  Further, the storage unit 6 includes a key-corresponding light emission pattern setting memory 6-8 shown in FIG. 21, and the user uses different light emission colors or different light emission colors for each key number based on the light emission pattern control table 6-7. Light emission pattern data can be set arbitrarily.

  According to FIG. 21, the common light emission color (red) is set for the key numbers 1 to 12, the light emission pattern data 1 is set for the key number 1, and the light emission timings for the key numbers 2 to 12, respectively. Light emission pattern data 2 to 12 having different values are set. Therefore, the key backlight is turned on / off at different emission timings (cycles) in a predetermined emission color (common color, for example, red) in the order of the numeric keys 1 to 9, numeric key 0, * key, and # key of the operation unit 2. To do.

  Note that the user can arbitrarily set the light emission color common to the three-color LEDs 4-1 to 4-12, and the light emission pattern data setting order for each key number can be arbitrarily set according to the key operation order of the user. Can do.

  Furthermore, the storage unit 6 includes a function-corresponding light emission pattern control table 6-9 shown in FIG. 22, and the light emission color and light emission pattern data of valid / invalid keys corresponding to each application function are stored in advance. The light emission pattern data can be arbitrarily set by the user based on the light emission pattern control table.

  The operation unit 2 is disposed on the key backlight 4 so as to irradiate each key.

  Next, the light emission pattern setting process of the light emission color of the key backlight will be described with reference to FIG. 18 together with FIG.

  When the user selects a light emission pattern setting mode by pressing a predetermined key of the operation unit 2 to set a light emission pattern of a desired key backlight emission color for each key (step S501 in FIG. 18), the display unit 3 is displayed. The color designation menu shown in FIG. 12 is displayed (S502).

  This color specification menu allows you to select any one of 12 colors as a common color in addition to 12 colors of red, green, blue, purple, yellow, white, orange, brown, light blue, yellow green, red purple, and bluish purple “Common” items are displayed.

  After the user selects “common” displayed on the display unit 3 with the cursor (S503), the cursor is moved to select an arbitrary emission color, for example, “red” (S504), and a predetermined key operation (for example, The red key is designated as a common emission color (red) for the input keys (numeric key, * key, # key) of the operation unit 2. When a different emission color is designated for each key, a desired emission color can be set without selecting the “common” item.

  Subsequently, when the user presses any key of the input keys (numeric key, * key, # key) of the operation unit 2, for example, the numeric key 1 (S505), the control unit 1 determines the key operation order of the user. Therefore, “1” is recorded in a counter (not shown) (S506).

  The control unit 1 determines the operation order based on the count value of the counter (S507). If the operation order is not “1”, the process proceeds to step S510 to determine the operation order, and if the operation order is “2”. In step S508, if the operation order is not "2", the operation orders "3" to "12" are similarly determined (S512, S514).

  If the determination result in step S507 is the operation order “1”, the key number is determined based on the key information pressed by the user (S508). If the key number is 1, the light emission pattern control table 6-7 is used. “Light emission pattern data 1” of “key pressing order 1” is read out from the light emission color, for example, the “red” color identification code and the light emission pattern data corresponding to the red color. The data is stored in the key corresponding light emission pattern setting memory 6-8 (S509).

  If the determination result in step S508 is not key number 1, it is determined whether or not it is key number 2 (numeric key 2) (S511). If numeric key 2 and the operation order is “1”, light emission is performed. From the pattern control table 6-7, the light emission color, for example, “red” color identification code and “light emission pattern data 1” of “key press priority 1” are read out from the light emission pattern data corresponding to red, and the key number 2 is read. Correspondingly, it is stored in the key-corresponding light emission pattern setting memory 6-8 of the storage unit 6 (S509).

  When the determination result of step S511 is the numeric key 2 and the operation order is “2”, the emission pattern, for example, the “red” color identification code and the emission pattern corresponding to red, from the emission pattern control table 6-7. The “light emission pattern data 2 of“ key pressing order 2 ”” is read from the data and stored in the key corresponding light emission pattern setting memory 6-8 of the storage unit 6 corresponding to the key number 2 (S509).

  Similarly, if the determination result in step S511 is not key number 2, key number 3 (numeric key 3) to key number 10 (numeric key 0) are sequentially determined, and the emission color, for example, from the emission pattern control table 6-7, for example, The light emission pattern data corresponding to the operation order determined in steps S507, S510 to S512, and S514 is read out from the “red” color identification code and the light emission pattern data corresponding to red, and stored in correspondence with the determined key number. The data is stored in the key-corresponding light emission luminance setting memory 6-8 of the unit 6 (S509).

  As described above, the light emission color of the key can be set to an arbitrary color, and the light emission pattern data for the key backlights of the three-color LEDs 4-1 to 4-12 corresponding to the user's key operation order and the key number is obtained. It can be set arbitrarily. In the key-corresponding light emission pattern setting memory 6-8 shown in FIG. 21, the user enters key number 1 (numeric key 1) to key number 10 (numeric key 0), key number 11 (* key), key number 12 ( Light emission pattern data 1 (large cycle ratio) to 12 (small cycle ratio) when operated in the order of # key) are set.

  In this case, the key backlight is turned on / off with a red emission color in a short cycle in the order of numeric keys (1 to 9, 0), * key, and # key. That is, the blinking cycle is accelerated in the order of the numeric keys (1 to 9, 0), the * key, and the # key. On the contrary, it is also possible to lengthen the blinking cycle.

  Next, a key backlight emission pattern control process will be described with reference to FIG.

  When an event occurs (step S601 in FIG. 19), the control unit 1 determines whether or not it is an incoming call (S602). If the determination result is an incoming call, the key-corresponding light emission pattern setting registered in the storage unit 6 in advance is determined. The light emission pattern data corresponding to the common light emission color (red) and the numbers of all keys (number keys 1 to 9, 0, * key, # key) are sequentially read from the memory (FIG. 21) (S603), and the light emission pattern control unit The data is transferred to the light emission pattern control drivers 9-1 to 9-12 arranged for the 9 keys (S604).

  The control unit 1 monitors the transfer of the common light emission color and the light emission pattern data to the light emission pattern control drivers 9-1 to 9-12, and detects the end of the transfer (S605), all the light emission pattern control drivers 9-1 to 9-1. 9-12 is instructed to turn on the key backlight (S606).

  When the light emission pattern control drivers 9-1 to 9-12 receive an instruction to turn on the key backlight from the control unit 1, all the keys have the designated common light emission color (red) and each key has a different light emission pattern. The key backlight is turned on (S607). Thereby, each key of the operation unit 2 is illuminated in red and with a different period.

  If the determination result in step S602 is not an incoming call, the control unit 1 detects the input key information (S608), and determines whether the key information is a request for starting a predetermined application function (for example, a game) (609). .

  If the determination result in step S609 is not a request for starting a predetermined application function, it is recognized that the operation is a call operation or a mail mode, the process proceeds to step S603, and the processes in steps S603 to S607 are executed. That is, all the keys are turned on / off with a different light emission color (common color) registered in advance in the key-corresponding light emission pattern setting memory 6-8 for each key.

  If the determination result in step S609 is a request for starting a predetermined application function, a specified function, for example, an application program for a game is started (S610). Here, the predetermined function refers to, for example, a game function, a stopwatch function, a calculator function, an alarm / alarm function, a barcode reading function, a camera imaging function, and the like. Here, a case where a game function is executed will be described as an example.

  The storage unit 6 includes a function-corresponding light emission pattern control table 6-9 shown in FIG. 22, and a key necessary (used) for the function operation for each function is a valid key, and a key unnecessary for the function operation (not used). Is used as an invalid key, and light emission pattern data, which is a light emission pattern control signal, is registered in correspondence with each key number in order to turn on the key backlight with a common light emission color and different periods.

  According to the function-corresponding light emission pattern control table 6-9 shown in FIG. 22, valid keys necessary for operating the functions A, B to N and invalid keys unnecessary for the operation are set to “1” and “0”. Different light emission pattern data are set for the valid key and the invalid key.

  In the case of function A (game function), key numbers 2 (numeric keys 2), key numbers 4, 5, 6 (numeric keys 4, 5, 6), key numbers 8 (numeric keys) 8) is set, red is set for each valid key, and light emission pattern data 1 having the maximum period is set.

  In addition, key number 1 (numeric key 1), key number 3 (numeric key 3), key number 7 (numeric key 7), and key numbers 9 to 12 (numeric key 0, * key, # key) are set as invalid keys. Then, red is set for each invalid key, and the light emission pattern data 6 that is a half of the maximum period is set.

  That is, the valid key is red with a long period and the invalid key is red with a period lower than the valid key. Therefore, the user can distinguish the valid key and the invalid key by the difference in blinking. Note that the light emission pattern data (flashing cycle) for the valid key and the invalid key can be arbitrarily set by the user.

  Similarly, the function B and the function N also have a key backlight flashing cycle by setting an arbitrary emission color and arbitrary emission pattern data in advance for an effective key and an unnecessary invalid key necessary for each function. Thus, the valid key and the invalid key can be distinguished.

  When the application of the game function is activated in step S610, the control unit 1 reads the key number, valid / invalid code, and each from the function corresponding light emission pattern control table (function A in FIG. 22) registered in the storage unit 6 in advance. The bright light emission pattern data, which is the light emission pattern control signal corresponding to the key number, is read (S611), and based on the valid / invalid key code, it is determined whether it is a valid key or invalid key (S612).

  The light emission pattern control drivers 9-2, 9-4, 9-5, 9-6, 9 of the light emission pattern control unit 9 corresponding to the key numbers 2, 4, 5, 6, 8 determined to be valid keys in step S612. The red identification code and “light emission pattern data 1” are transferred to −8 (S613).

  In addition, the light emission pattern control drivers 9-1, 9-3, 9-7, 9- of the light emission pattern control unit 9 corresponding to the key numbers 1, 3, 7, 9, 10-12 determined as invalid keys in step S612. 9, 9-10 to 9-12, the red identification code and the “light emission pattern data 6” are transferred (S614).

  The control unit 1 monitors the transfer of the light emission pattern data to the light emission pattern control drivers 9-1 to 9-12. When the transfer is detected to be completed (S615), all the light emission pattern control drivers 9-1 to 9-12 are detected. Is instructed to turn on the key backlight (S616).

  When the light emission pattern control drivers 9-1 to 9-12 receive an instruction to turn on the key backlight from the control unit 1, the valid key is red with a long period and the invalid key is red with a short period. It is made to light (S617).

  Although the description in the case where the function designation in step S609 is the function B and the function N is omitted, the key backlight may be turned on / off with an arbitrary light emission color and an arbitrary blinking cycle. it can.
