BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal device, and in particular, can confirm the type of received message or the priority of distribution without requiring an extra operation, and does not require an extra operation when displaying acquired content data. The present invention relates to a mobile communication terminal device capable of turning on a light.
[0002]
[Prior art]
In a mobile phone or a mobile information terminal (hereinafter referred to as a mobile communication terminal device) equipped with a Web browser, content data is acquired from a Web site server, a message is received from a Web site server, or an e-mail is transmitted / received. The acquired data, the received message or the electronic mail is displayed on the display unit.
[0003]
In general, in such portable communication terminal devices, information can be identified by illuminating the display unit (liquid crystal surface) with a backlight so that the information displayed on the display unit can be identified at night or when the surroundings are dark. The method to take is taken. However, the power consumption of this backlight is larger than that of other parts. Therefore, in order to minimize the power consumption, the backlight of the display unit is usually turned on / off by a timer. .
[0004]
For this reason, for example, when a message or e-mail (hereinafter simply referred to as a message) received from a Web site server is long, the backlight is turned off after the user displays the message and finishes reading it. Therefore, when reading the continuation of the message, some operation is required for the portable communication terminal device. Therefore, in mobile communication terminal devices with a small display screen, it is not possible to display all at once when displaying a long message, and attention is paid to the continuity of user operations when reading a long received message. A method is employed in which the presence or absence of an operation is monitored by a timer and the backlight is turned on by resetting the timer for each operation.
[0005]
However, for example, if there is a large difference between the time for reading the displayed message and the time for which the backlight of the display is lit, the backlight is turned off before the user finishes reading all of the messages. Each time, the user must perform an operation to turn on the backlight. For this reason, for example, a terminal device as described in JP-A-9-325728 has been proposed. In this terminal device, the lighting time of the backlight is variably set according to the amount of data displayed on the display unit. According to this terminal device, even when the amount of data to be displayed is large, the backlight is turned on for a predetermined time according to the amount of data, so that all the displayed data can be confirmed.
[0006]
[Problems to be solved by the invention]
However, the conventional mobile communication terminal device as described above has the following problems.
(1) The lighting color of the backlight is displayed in the same color regardless of the user's operation and the message to be displayed. Therefore, when the user does not notice the reception of the message or looks at the displayed message, Therefore, there is a problem in that it is not possible to know what kind of message it has and what kind of priority, and it is necessary to check the contents later, which requires extra operations.
(2) Also, for example, when acquiring the data of the link destination displayed in the content acquired from the website, communication is started by a predetermined operation, the target data is acquired by the user, Although the data is displayed on the display screen, no user operation occurs during the communication from the operation for acquiring the link destination data to the acquisition of the link destination data. When the backlight for display is turned off and the acquired data is displayed with the backlight turned off, or when the backlight is turned off during the display and this is an operation in a dark place However, there is a problem in that the displayed data cannot be identified and an extra operation for lighting must be performed.
[0007]
Therefore, an object of the present invention is to check the type of received message or the priority of distribution without requiring an extra operation, and without requiring an extra operation when displaying the acquired content data. Is to provide a mobile communication terminal device that can be turned on.
[0008]

It is displayed on the display unit 23 of the mobile phone 20 by the operation of the user 1 of the phone 20. At this time, the display backlight control unit 25 performs lighting control in accordance with the type, priority, and length of the data to be displayed, acquired data, message, or e-mail.
[0017]
Hereinafter, with reference to the flowcharts of FIGS. 3 and 4, operations when displaying a received message and an e-mail and when displaying linked data displayed in the content will be described.
[0018]
FIG. 3 is a flowchart showing an operation at the time of display related to a received message and electronic mail.
First, it is determined whether or not to display the received message by the operation of the user 1 of the mobile phone 20 or the reception of the message (step S301). In cases other than the display processing of the received message (determination in step S301). : No), the lighting time of the backlight is set in the timer 26 with the reference value in the apparatus (step S305).
[0019]
When the user 1 selects display processing of the received message (determination in step S301: Yes), the message type, priority, and length are acquired from the display target message stored in the memory 21 ( In step S302, the type of message to be displayed is determined (step S303).
[0020]
When the message displayed by the user 1 is a message from the server 10 on the website (No in step S303), the display color of the backlight is changed to the color for displaying the message on the website (step S304). The lighting time of the backlight is set in the timer 26 with a reference value in the apparatus (step S305).
[0021]
On the other hand, if the message displayed by the user is a received mail (determination in step S303: Yes), the priority of distribution of the received mail is first determined (step S306). If the distribution priority is normal (step S306) (S306: No) If the backlight color uses the system standard color and the delivery priority is express delivery (Yes in step S306: Yes), the display color information of the backlight is displayed as an express mail reception. The color is changed to the backlight color for use (step S307).
[0022]
After confirming the distribution priority in the received mail display, the number of display characters is calculated from the message length (step S308). As a result of calculating the number of display characters, it is determined whether or not the lighting time is in time with the reference value in the device (step S309). If the lighting time is in time with the reference value in the device (determination in step S309: Yes), reception is performed. Similarly to the processing other than the message, the backlight lighting time is set in the timer 26 as a reference value in the apparatus (step S310). If the reference value is exceeded (No in step S309), the backlight power is determined from the number of display characters. The lighting time is calculated (step S311).
[0023]
In this lighting time calculation method, first, it is assumed that the speed at which a person reads a document per minute is about 300 characters, and the number of characters at this time is “1”. Therefore, the ratio of the number of displayed characters to this “1” is calculated. Then, the calculated value and the ratio of the reference value of the backlight lighting time in the apparatus to the document reading speed (that is, the ratio of how many times the reference value in the apparatus corresponds to the document reading speed). It is calculated by multiplying that value and the reference value of the lighting time of the backlight in the apparatus. The value obtained by the calculation is set in the timer 26 as the lighting time of the backlight (step S312).
[0024]
After the backlight lighting time is set in the timer 26, a message to be displayed is displayed on the display unit 23 (step S313), and information on the backlight lighting color corresponding to the display message is displayed on the display backlight control unit 25. The setting is made (step S314), and the backlight is turned on (step S315).
[0025]
After the backlight is turned on, it is determined whether or not the timer 26 has timed out (step S316). If the timer 26 has not timed out (determination in step S316: No), the time-out is continuously monitored.
[0026]
If the timer 26 has timed out (determination in step S316: Yes), it is determined whether or not an event has occurred from the key operation using the operation unit 22 by the user or the peripheral device interface unit 27 after the time-out (step S316). S317) If there is no key operation by the user or no event has occurred from the peripheral device interface unit 27 (No in step S317), the display backlight control unit 25 is controlled to turn off the backlight. (Step S318).
[0027]
If an operation from the user or an event from the peripheral device interface unit 27 occurs after the timeout (Yes in Step S317), the reference value in the device is set in the timer 26 (Step S319), and the display backlight The controller 25 is controlled to control backlight lighting (step S314).
[0028]
In this way, the lighting color and lighting time of the terminal device backlight are controlled by the type, priority, and length of the received message, so you can easily see what the received message is displaying at a glance. In addition, even in a long message, the backlight of the display unit can be turned on until the user finishes reading the message, and unnecessary operations on the terminal when reading the message can be reduced. Further, by dynamically controlling the lighting time of the backlight, it is possible to minimize the battery consumption due to the backlight lighting of the display unit.
[0029]
FIG. 4 is a flowchart showing the operation of backlight control when acquiring website data or data stored in the website or mail server.
[0030]
First, it is determined whether or not the operation of the user 1 of the mobile phone 20 is acquisition of content data on the website (step S401), and in cases other than acquisition of content data on the website (determination in step S401: NO) After the backlight lighting time is set in the timer 26 with the reference value in the apparatus (step S404), the backlight is turned on (step S405).
[0031]
When the user performs an operation for acquiring content data on the website, it is determined whether the data to be acquired has already been acquired and stored in the memory 21 (step S402).
[0032]
In the case of already acquired data (judgment in step S402: NO), the display color of the backlight is changed to the color of the backlight for displaying the content of the website (step S403), and the backlight lighting time is set in the apparatus. After setting the timer 26 with the reference value (step S404), the backlight is turned on (step S405).
[0033]

The lighting of the backlight at this time is due to the user performing an operation for data acquisition.
[0034]
Communication for content acquisition or display of other content in the terminal by the user's operation or other processing other than content display is displayed. After the backlight is lit, the backlight lighting timer 26 It is determined whether or not a timeout has occurred (step S409). If the timeout has not occurred (determination in step S409: No), the timeout is continuously monitored.
[0035]
If the backlight lighting timer 26 has timed out (determination in step S409: Yes), it is determined whether a key operation using the operation unit 22 from the user or an event from the peripheral device interface unit 27 has occurred after the time-out. If it is determined (step S410) and no key operation using the operation unit 22 from the user or no event has occurred from the peripheral device interface unit 27 (determination in step S410: NO), the backlight control unit 25 is controlled. The backlight is turned off (step S411).
[0036]
When an operation from the user or an event from the peripheral device interface unit 27 is confirmed after the timeout (step S410: YES), the reference value in the device is set in the backlight lighting timer 26 (step S412). Lighting control is performed on the display backlight control unit 25 (step S413).
[0037]
After the backlight is turned off, it is determined whether or not communication processing is in progress (step S414). If communication is not in progress (determination in step S414: NO), the next user waits for the operation and the processing ends. If communication is in progress (determination in step S414: YES), it is determined whether communication is continuing (step S415). If communication has not ended (determination in step S415: NO), communication continues. If the communication has been completed (determination in step S415: YES), the display color of the backlight is set (step S416), and the backlight lighting timer is set to the reference value in the apparatus. (Step S417).
[0038]
After the backlight lighting time is set in the timer 26, the acquired data to be displayed is displayed on the display unit 23 (step S418), and the backlight lighting color information corresponding to the display message is displayed in the display backlight control unit 25. The backlight is turned on (step S419).
[0039]
The processing after the backlight is turned on is the same as the processing from step S409 to step S413 described above.
[0040]
As described above, since the backlight is turned on together with the data to be displayed after the data acquisition is completed, during the communication from the operation for acquiring the link destination data displayed in the acquired content until the data is acquired. Unnecessary operations for turning on the backlight that was turned off can be reduced.
[0041]
