[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control method for a mobile communication apparatus which displays a key operation section or a display section by an input operation of the key operation section, and an apparatus thereof.

[0002]

2. Description of the Related Art Conventionally, as a method for controlling a lighting unit of a portable telephone, for example, a structure shown in FIGS. 5 and 6 has been known.

In the method of controlling the lighting unit of the portable telephone shown in FIGS. 5 and 6, the key input detection circuit 24 determines whether or not there is an input operation of a key operation unit 27 for inputting a telephone number and various settings. (Step C2). And
When the key input detection circuit 24 does not detect an input operation of the key operation unit 27, the display unit 2 that displays the input contents
The first illuminator 26 for illuminating the key 5 and the second illuminator 28 for illuminating the key operation unit 27 are turned off (step C1).

When the key input detection circuit 24 detects an input operation of the key operation section 27, the key input detection circuit 2
4 outputs a key input detection signal (step C3), activates the timer circuit 23 (step C4),
The first lighting unit 26 and the second lighting unit 28 are turned on (Step C5). Thereafter, when a predetermined time set in advance by the timer circuit 23 has elapsed, the first lighting unit 26 and the second lighting unit 28 are turned off (step C).
1).

When the key input detection circuit 24 detects an arbitrary key input operation by the key operation section 27 before the timer circuit 23 has passed a predetermined time (step C6).
The content of the input operation that has been input is output to the control unit 21, and signals such as predetermined characters and symbols input by the control unit 21 are controlled to display predetermined characters and symbols on the display unit 25 and to display the mobile phone. Enable normal operation,
A key input detection signal is output from the key input detection circuit 24 again (step C3), and the predetermined time of the timer circuit 23 is reset and started again (step C4).
And the control of turning on the second illumination unit 28 (step C5) is repeated.

Therefore, if the key operation unit 27 is operated with the timer circuit 23 not having passed the predetermined time,
Since the first illuminator 26 and the second illuminator 28 continue to be lit, the power consumption of the mobile phone increases, causing battery consumption.

Therefore, as a configuration for limiting the continuous time of illumination to reduce power consumption and suppress battery consumption, a configuration described in, for example, Japanese Patent Application Laid-Open No. 9-149444 is known.

The device disclosed in Japanese Patent Application Laid-Open No. 9-149444 includes a timer A for measuring a normal lighting time and a timer B for measuring a maximum continuous lighting time, and the timers A and B are activated by operating an illumination switch. When the control unit determines that the set time of either of the timers A and B has been reached, the control unit turns off the lighting.

However, Japanese Patent Application Laid-Open No. Hei 9-14944 describes
In the device described in Japanese Patent Application Laid-Open No. 4 (1999) -2004, since the lighting is performed for the maximum continuous lighting time from the operation of the lighting switch, a specific lighting switch is separately required, and the configuration becomes complicated. There is a problem that a setting operation for lighting is required, and the operation is complicated.

[0010]

As described above, FIG.
In the conventional control method of the lighting unit in the mobile phone shown in FIG. 6, when the key operation unit 27 is operated to input while the predetermined time has not elapsed, the first lighting unit 26 and the second lighting unit 28 continue to light. Therefore, the power consumption of the mobile phone increases, which causes the battery to be consumed.

Further, the configuration described in Japanese Patent Application Laid-Open No. 9-149444 requires a separate lighting switch, which complicates the configuration. In addition, an input operation by a key operation unit for inputting a telephone number and various settings in a mobile phone is performed. Apart from this, there is a problem that the operation of the lighting switch is required and the operation becomes complicated.

The present invention has been made in view of the above points, and provides a lighting control method for a mobile communication device and a device therefor, which have a simple configuration and suppress an increase in power consumption due to unnecessary continuous lighting. Aim.

Next, the operation of the above embodiment will be described with reference to the flowchart shown in FIG.

FIG. 2 is a flowchart showing the operation of the mobile phone according to one embodiment of the present invention.

First, when there is no input operation on the key operation unit 7, the key input detection circuit 4 does not detect the input operation on the key operation unit 7, the timer circuit 3 is not activated, and the illumination control unit 2 is in the first state. The illuminator 6 and the second illuminator 8 are turned off (step A1).

When the user operates the mobile phone, that is, operates various keys of the key operation unit 7 at a certain interval, the key input detection circuit 4 detects an input operation by the key operation unit 7 (step A2) and performs a predetermined detection. A signal is output (step A3). The timer circuit 3 is activated by the output detection signal (step A4), and the illumination control section 2 recognizes the activation of the timer circuit 3 and turns on the first illumination section 6 and the second illumination section 8 (step A5). ), The first illumination unit 6 illuminates the display unit 5, and the second illumination unit 8 illuminates the key operation unit 7.

On the other hand, the key input contents input by the input operation of the key operation unit 7 are output to the control unit 1 as they are,
The control unit 1 controls predetermined characters, symbols, and the like input to display predetermined characters, symbols, and the like on the display unit 5 to enable normal operation of the mobile phone.

Then, the illumination control unit 2 continuously lights the first illumination unit 6 and the second illumination unit 8 until the timer circuit 3 measures a predetermined time, and when the timer circuit 3 measures the predetermined time (step S1). A6), the first illuminator 6 and the second illuminator 8 are turned off (step A1).

Note that while the timer circuit 3 has not counted the predetermined time and the first illumination unit 6 and the second illumination unit 8 are lit, any key is operated by the key operation unit 7. Then, even if the key input detection unit 4 detects an input operation of the key operation unit 7, the input operation is performed for the first time and the first illumination unit 6 and the second
The key input detection circuit 4 invalidates the input operation other than the input operation of the key whose illumination unit 8 is turned on, and does not output the detection signal to the timer circuit 3.

As described above, even when the input operation of the key operation unit 7 is detected, the first illumination unit 6 and the second illumination unit 8 are turned on for a predetermined time, and the input operation of an arbitrary key is detected within the predetermined time. Since it is determined that the input operation other than the key input operation detected for the first time is invalid and the illumination is performed only within a predetermined time, an increase in power consumption due to unnecessary continuous illumination can be suppressed, and the consumption of the battery can be suppressed.

Next, another embodiment will be described with reference to FIGS.

FIG. 3 is a block diagram showing a configuration of a mobile phone according to another embodiment of the present invention. FIG. 4 shows FIG.
6 is a flowchart for explaining the operation of the mobile phone shown in FIG.

The embodiment shown in FIG. 3 and FIG.
A first timer circuit 1 connected to a key input detection circuit in place of the timer circuit 3 of the embodiment shown in FIGS.
2 and a second timer circuit 13. Then, only the first timer circuit 12 is connected to the illumination control unit 2.

Next, the operation of the other embodiment will be described with reference to the flowchart shown in FIG.

First, similarly to the embodiment shown in FIGS. 1 and 2, when there is no input operation on the key operation unit 7, the key input detection circuit 4 does not detect the input operation on the key operation unit 7,
The timer circuit 3 does not start, and the lighting control unit 2
And the 2nd illumination part 8 is turned off (step B1).

When the user operates the mobile phone, that is, operates various keys of the key operation unit 7 at a certain interval, the key input detection circuit 4 detects an input operation by the key operation unit 7 (step B2) and performs a predetermined detection. A signal is output (step B3). In response to the output detection signal, the first timer circuit 12 is activated (Step B4), and the illumination control unit 2 recognizes the activation of the first timer circuit 12 and turns on the first illumination unit 6 and the second illumination unit 8. (Step B5), the first illumination unit 6 illuminates the display unit 5, and the second illumination unit 8 operates the key operation unit 7.
To illuminate.

On the other hand, the key input contents input by the input operation of the key operation unit 7 are output to the control unit 1 as they are,
The control unit 1 controls predetermined characters, symbols, and the like input to display predetermined characters, symbols, and the like on the display unit 5 to enable normal operation of the mobile phone.

Then, the lighting control unit 2 continuously lights the first lighting unit 6 and the second lighting unit 8 until the first timer circuit 12 measures a first predetermined time.
Time the first predetermined time (step B6), the first lighting unit 6 and the second lighting unit 8 are turned off (step B6).
7).

While the time of the first timer circuit 12 has not elapsed the first predetermined time and the first illumination unit 6 and the second illumination unit 8 are lit, an arbitrary operation is performed by the key operation unit 7. Even if the key input operation is performed and the key input detection unit 4 detects the input operation of the key operation unit 7, the input operation is performed for the first time and the first illumination unit 6 is operated.
The key input detection circuit 4 invalidates the input operation and does not output a detection signal to the first timer circuit 12 except for the input operation of the key whose second illumination unit 8 is turned on. However, the contents of the input operation of the key operation unit 7 are output to the control unit 1, and the input signals of predetermined characters and symbols are controlled by the control unit 1 and the corresponding predetermined characters and symbols are displayed on the display unit 5. Is displayed and recognized as an operation of the mobile phone.

Then, in step B7, the first timer circuit 12 counts a first predetermined time, and the illumination control unit 2 turns off the first illumination unit 6 and the second illumination unit 8 so that the second
The timer circuit 13 is started at the same time, and
Timing of the second predetermined time is started (step B8). An arbitrary key is input by the key operation unit 7 in a state where the time of the second timer circuit 13 has not elapsed the second predetermined time and the first illumination unit 6 and the second illumination unit 8 are kept turned off. Even if the key input detection unit 4 is operated to detect the input operation of the key operation unit 7, the key input is performed except for the input operation of the key whose first illumination unit 6 and the second illumination unit 8 are illuminated for the first time. The detection circuit 4 invalidates the input operation and does not output a detection signal to the first timer circuit 12. However, the contents of the input operation of the key operation unit 7 are output to the control unit 1, and the input predetermined characters,
Signals such as symbols are controlled by the control unit 1 to display corresponding predetermined characters and symbols on the display unit 5 and recognized as operation of the mobile phone.

Therefore, even after the first timer circuit 12 has passed the predetermined time, the input operation of the key operation unit 7 is continuously performed before the second timer circuit 13 has passed the second predetermined time. The extinguishing of the first lighting unit 6 and the second lighting unit 8 is continued.

When the input operation of any key is interrupted or stopped and the second timer circuit 13 has counted the second predetermined time, that is, when the second timer circuit 13 has completed the time measurement (step B10), the key is pressed. The apparatus enters a standby state in which a key input operation by the operation unit 7 is detected (step B1).

Thus, after illumination for the first predetermined time,
Even if the key is operated, the lighting is not performed for the second predetermined time, so that the trouble of repeatedly turning on and off the first lighting unit 6 and the second lighting unit 8 can be prevented, and an increase in power consumption due to unnecessary turning on and off of light is repeated. And battery consumption can be suppressed.

Although the mobile phone has been described in the embodiments shown in FIGS. 1 and 2 and the embodiments shown in FIGS. 3 and 4, the present invention can be applied to any other mobile communication device. That is, any mobile communication device including an operation unit for performing an input operation for performing normal communication, a display unit for displaying the operation content, and a lighting device for illuminating the display unit or the operation unit may be used.

[0042]

According to the present invention, the input operation of the key operation unit is detected, the illumination unit is turned on for a predetermined time, and even if the input operation of an arbitrary key is detected within the predetermined time, the key detected for the first time is detected. Since the input operation other than the input operation is determined to be invalid and the illumination is performed only within a predetermined time, an increase in power consumption due to unnecessary continuous illumination can be suppressed, and the consumption of the battery can be suppressed.

Further, after the illumination for a predetermined period of time, even if a key is operated, the illumination is not performed for a predetermined period of time. The battery consumption can be suppressed by suppressing the increase in the power consumption.
