2. Description of the Related Art Non-emissive liquid crystal display elements are widely used as display elements in conventional mobile phones. When a mobile phone equipped with such a non-light emitting type liquid crystal display device is operated in a dark place, the liquid crystal display device does not emit light, and therefore the liquid crystal display cannot be visually confirmed. Therefore,
The above-mentioned problems are solved by providing an illumination device for illuminating the operation unit and the display unit.

In some conventional illumination methods, the illumination is turned on / off in response to a key input from the operation unit.

Further, as disclosed in Japanese Patent Publication No. 3-29328, there is disclosed a method in which the brightness is judged from the ambient brightness and the lighting is switched on and off.

[0005]

Since the operation unit does not perform any operation during a call, it is often unnecessary to illuminate the display unit and the operation unit during the call. As a conventional lighting method in a mobile phone with a lighting function, a method of controlling lighting and turning off of lighting according to a key input on an operation unit or ambient brightness is adopted. Therefore, there is a state in which the lighting is on for a certain period of time even when the call state is entered.
Therefore, there is a problem that unnecessary lighting is consumed and unnecessary power is consumed.

The present invention solves the above problems and adjusts the amount of illumination by measuring the light intensity of the surroundings in accordance with the function of controlling the turning on / off of the illumination depending on the line connection state, the incoming / outgoing call operation and the key input. It is an object of the present invention to provide a mobile phone with a lighting function having a function to operate.

[0007]

According to the present invention, a display section, an operating section, an illuminating means for illuminating them, a light receiving circuit for measuring the peripheral luminous intensity of the display section and the operating section, and the light receiving section. It is configured to include control means for receiving light intensity information from a circuit, controlling the lighting means according to the light intensity information, and turning on / off the light, and the control means is a line connection state of an incoming / outgoing call and a call. There is provided a mobile phone with a lighting function, which is characterized in that the lighting means is controlled according to a key input from the operation section to turn on / off the lighting.

Further, according to the present invention, when the incoming and outgoing call operation is performed, the control means operates the light receiving circuit, judges the necessity of illumination from the light intensity information from the light receiving circuit, and the illumination is performed. If necessary, a lighting turn-on request is sent to the lighting means, and in the case of a call state, it is determined whether or not the lighting is turned on. If the lighting is turned on, a lighting turn-off request is sent to the lighting means. A mobile phone with a lighting function characterized by the above is obtained.

When an illumination lighting request is issued, the control unit 2
In response to the lighting lighting request, the lighting circuit 3 is driven and the lighting is turned on (step 11). Next, the light receiving circuit 6 measures the luminous intensity around the display unit 5 and the operation unit 4 (step 1).
2). Next, the control unit 2 calculates the amount of illumination required to illuminate the display unit 5 and the operation unit 4 from the luminous intensity measured by the light receiving circuit 6 (step 13). Next, the control unit 2 controls the illumination circuit 3 so that the amount of illumination is obtained (step 1).
4). Next, the control unit 2 causes the display unit 5 and the operation unit 4 to operate.
It is judged whether or not the lighting of No. 1 needs to be turned off (step 15), and if there is no request to turn off the lighting, the process returns to step 12, and if there is a request to turn off the lighting, it is turned off (step 1
6), the process ends.

Next, the operation of turning on and off the illumination will be described with reference to FIG. FIG. 3 is a flow chart showing the flow of the operation of turning on and off the illumination in the present invention.

At step 20, various judgments are made in processes other than the illumination process. For example, various judgments are made in controlling transmission / reception. Here, the key processing (step 21), the outgoing / incoming call (step 31), and the call (step 41) are performed in parallel on the software.

First, the operation of turning on and off the illumination when the key processing is performed on the operation unit 4 will be described. Operation part 4
It is determined whether or not the key input is performed in step 22 (step 22), and if the key input is performed, it is further determined whether or not the illumination is turned on (step 23), and the illumination is turned on. If so, the illumination process corresponding to the key process ends there. If the illumination is not turned on, the light receiving circuit 6 detects the light around the display unit 5 and the operation unit 4 and measures the light intensity thereof (step 24). At this time, it is determined whether or not it is necessary to turn on the illumination around the display unit 5 and the operation unit 4 (step 25). If it is not necessary to turn on the illumination (if there is no illumination lighting request), the illumination process according to the key process ends there. If it is necessary to turn on the illumination (if there is a request to turn on the illumination), the illumination is turned on (step 26), and the illumination processing corresponding to the key processing ends. or,
When the key input is not performed in the operation unit 4 (step 22), it is determined whether or not the lighting is turned on (step 27), and if the lighting is turned on, after a predetermined time has passed (step 28). The illumination is turned off (step 29), and the illumination processing corresponding to the key processing ends. If it is determined in step 27 that the lighting is not turned on, the lighting processing corresponding to the key processing ends there.

Next, the operation of turning on and off the illumination when a call originating / receiving operation occurs will be described. When an incoming / outgoing call operation occurs (step 31), the light receiving circuit 6 detects the light around the display unit 5 and the operation unit 4 and measures the light intensity thereof (step 32). At this time, the display unit 5 and the operation unit 4
It is determined whether or not it is necessary to turn on the illumination around the area (step 33). Here, if it is not necessary to turn on the illumination (if there is no illumination lighting request), an incoming / outgoing call process (step 3)
5) is performed, and the lighting process when the incoming / outgoing call operation occurs is completed. If it is necessary to turn on the illumination (if there is a request to turn on the illumination), the illumination is turned on (step 34), the incoming / outgoing call processing (step 35) is performed, and the illumination processing when the incoming / outgoing call operation occurs is completed.

Next, the operation of turning on and off the illumination during a call will be described. When call operation occurs (Step 4)
1) determine whether the lights are off (step 4
2) If the light is off, call processing (step 4)
4) is performed, and the lighting process during the call ends. If the light is on, turn off the light (step 43),
The call process (step 44) is performed, and the illumination process during the call ends.
