Description

<Desc/Clms Page number 1> A Method of Controlling a Back Light in a Portable Communication Terminal Apparatus Background of the Invention 1. Field of the Invention The present invention relates to a method of controlling a back light in a portable communication terminal apparatus.
2. ,Description of the Related Art In a portable phone or portable information terminal apparatus (hereinafter, to be referred to as a portable communication terminal apparatus) , a Web browser may be installed therein, and a content data is acquired from a server on a Web site. Also, it is possible to receive a message from the server on the Web site and to transmit and receive an E-mail. The acquired data, the received message or the E-mail are displayed on a display section of the portable communication terminal apparatus.
In such a portable communication terminal apparatus, a method is adopted in which the display section or a liquid crystal device is
<Desc/Clms Page number 2>
illuminated by ..a back light, whe#n._the peripheral portion of the portable communication terminal apparatus is dark as in night. However, this back light requires a large amount of power consumption, compared with the other parts. Therefore, turning-on and turning-off of the back light of the display section are generally controlled by a timer to suppress the power consumption to the minimum.
Therefore, there is a case that the back light is turned off before the user completely reads a message or E-mail after the message is displayed, when the message received from the server of the Web site is long. In this case, an operation to the portable communication terminal apparatus becomes necessary to continue to read the message. Therefore, in the portable communication terminal apparatus in which a display screen is small, a method is adopted in which an operation is monitored by use of a timer. The timer is reset to continue to turn on the back light, every time the operation is carried out.
However, when the difference between the time necessary to read the displayed message and the time during which the back light of the display section is turned on is large, the back
<Desc/Clms Page number 3>
light is turned off before the -u-s.e-r completely reads the whole message. In this case, the user must operate an operation unit to turn on the back light.
For this reason, a terminal apparatus is proposed in Japanese Laid Open Patent Application (JP-A-Heisei 9-325728). In this terminal apparatus, the lighting time of the back light is variably set in accordance with a quantity of data which is displayed on the display section. According to the terminal apparatus, even when the quantity of data to be displayed is large, the whole displayed data can be confirmed, because the back light is turned on for a time determined in accordance with the amount of data.
However, according to the portable communication terminal apparatus as mentioned above, there are following problems. (1) The lighting color of the back light is the same color as in a usual case, irrespective of the operation of the user and the displayed message. There is a case that the user does not recognize the reception of the message. Also, the user does not understand the priority and kind of the message when seeing the displayed message. Therefore, the content must be confirmed later. Thus, there is a problem that the extra operation
<Desc/Clms Page number 4>
becomes necess-ary-..
(2) When data at a link destination displayed in the acquired content data is acquired, communication is started through a predetermined operation. Thus, the acquired data is displayed on the display screen. In this case, the operation of the user does not occur during the communication from the operation to acquire data at the link destination to the acquisition of the data from link destination. Therefore, the back light for the display section is turned off based on the timer, when a predetermined time elapsed. The display of the acquired data is performed in the condition in which the back light has been turned off. Or, the back light is turned off on the display way. Therefore, there is another problem that an extra operation for turning on the back light must be carried out, when the terminal apparatus is in a dark place.
In conjunction with the above description, a portable phone with a display function is disclosed in Japanese Laid Open Patent Application (JP-A-Heisei 9-27844). In this reference, a back light is turned on in response to a key operation of a communication start key or a call arrival (steps 51 to 54), when the peripheral portion is dark. Then, a timer is
<Desc/Clms Page number 5>
started (step -55 )@. The back light- is turned off when speech input is detected or after a predetermined time is elapsed (steps 56 to 58).
Also, a portable radio phone with a back light apparatus is disclosed in Japanese Patent No. 2,669,404. In this reference, the portable radio phone is composed of a back light illuminating a display section, and a time outputting a current time data. The portable radio phone is further composed of a calendar calculating section outputting a current month data and an input section used to input a latitude data as a geographic data of a usage position. A lighting time zone is set based on a sun rising time and a sun set time which are determined based on the month data and the latitude data and stored in a back light lighting time zone setting memory. A control section controls the back light to be turned on when the current time corresponding to the current time data is within the back light lighting time zone stored in the back light lighting time zone setting memory.
Also, an image display apparatus is described in Japanese Laid Open Patent Application (JP-A-Heisei 8-327976). In this reference, a microcomputer has a counter function
<Desc/Clms Page number 6>
(5) and a memory (6). The microcomputer turns on a back light in response to an operation of a remote controller. The counter function (5) counts a time and compares the count with a data stored in the memory (6). When the count reaches the data, the microcomputer turns off the back light.
Summary of the Invention The invention provides a method of controlling a back
<Desc/Clms Page number 7>
light in a portable communication-terminal apparatus, includes: designating a lighting color; setting a lighting time in a timer; displaying a specific data on a display section; turning on a back light to illuminate the display section in the designated lighting color; and turning off the back light when the timer is in a time-out state.
Here, when the specific data is message data received from a server on a Web site, a priority of distribution of the message data may be determined, and the lighting color may be designated based on the determined priority of distribution of the message data.
Also, a standard color may be designated as the lighting color when the priority of distribution of the message data is ordinary, and a specific color as the lighting color when the priority of distribution of the message data is express.
Also, the lighting time may be in the timer based on a length of the message data.
In order to set the lighting time, a standard time value may be as the lighting time
<Desc/Clms Page number 8>
in the timer when-the length of 't he message data is equal to or shorter than a predetermined length, and a value for the message data may be calculated to set the calculated value as the lighting time to the timer when the length of the message data is longer than the. predetermined length.
In addition, a standard time value may be set as the lighting time in the timer in response to an operation of an operation unit by a user after the timer is in the time-out state such that the back light is turned on again. At this time, the back light is turned off when the timer is in the time-out state.
Also, the lighting color may be designated to a predetermined color when the specific data is content data acquired from a server on a Web site. In this case, acquisition of the content data from the server is started, and a standard time value is set in the timer after the acquisition of the content data is ended. Also, the back light is turned on again after the acquisition of the content data is ended. The back light is turned off when the timer is in a time-out state.
Also, the standard time value may be set in the timer in response to an operation of an
<Desc/Clms Page number 9>
operation unit-by a user when th'e -timer is in the time-out state after the acquisition of the content data.

Description of the Preferred Embodiments Hereinafter, a preferred portable communication terminal apparatus for performing the method of the present invention will be described in detail with reference to the
<Desc/Clms Page number 10>
attached drawings. ` Fig. 1 is a diagram showing a communication system to which the portable communication terminal apparatus such as a portable phone or a mobile phone is applied. Fig. 2 is a block diagram showing the structure of the portable communication terminal apparatus for performing the method according to the embodiment of the present invention ._ As shown in Fig. 1, a content data on a server 10 on a Web site is acquired to a portable communication terminal apparatus 20 of a user 1 via a gateway 12, a switching apparatus 13, and a radio base station 14. Also, a message or an E- mail is transmitted from the server 10 on the Web site or from a mail server 11 on the Internet to the portable communication terminal apparatus 20 of the user 1 via the gateway 12, the switching apparatus 13, and the radio base station 14. It should be noted that the reference numeral 23 denotes an example of the content data displayed on a display section of the portable communication terminal apparatus 20.
As shown in Fig. 2, the portable communication terminal apparatus 20 is composed of a memory 21, an operation section 22, a display section 23, a display control section 24,
<Desc/Clms Page number 11>
arid', a back light control section` 2-5 . The portable communication terminal apparatus 20 is further composed of a timer 26, a radio section 29, a back light 30, a peripheral unit interface section 27 and a control section 28. The memory 21 stores data at the link destination displayed in the content data on the server 10 on the Web site and the message or E-mail from the server 10 or the mail server 11 on the Web site. The operation section 22 is used to carry out a general function operation of the portable communication terminal apparatus 20. The display section 23 displays the content data, message or E mail and the content of the operation by the user of the portable communication terminal apparatus 20. The display control section 24 controls the display section 23 in response to a display control instruction from the control section 28. The back light control section 25 controls the back light 30 to be turned on or turned off in accordance with a kind, priority and length of the message in response to a back light control instruction from the control section 28. The back light control instruction includes a back light turn-on instruction and a back light turnoff instruction. The timer 26 is, used to determine the lighting time of the back
<Desc/Clms Page number 12>
light 30. The-peripheral unit interface section 27 functions as an input/output section to connect the portable communication terminal apparatus with an external system (not shown). The control section 28 controls the whole of portable communication terminal apparatus 20.
In the above structure, the data at link destination displayed in the content transmitted from the server 10 on the Web site or a message or E-mail from the server 10 on the Web site is stored in the memory 21 of the portable communication terminal apparatus 20. The content or the message or E-mail is displayed on the display section 23 of the portable communication terminal apparatus 20 through the operation of the user 1 of the portable communication terminal apparatus 20. At this time, the back light control section 25 carries out the turning-on and turning-off controls based on the kind of the content to be displayed and the priority and length of the content to be displayed. The kind indicative of whether the content data to be displayed is the acquired data, the message or the E-mail.
The operations when the received message or E-mail is displayed and the operation when the data at link destination displayed in the content
<Desc/Clms Page number 13>
is displayed will-be described. `Figs. 3A and 3B are flow charts showing the operation in case of display of the received message or E-mail.
First, whether the displaying process of a received message is to be carried out is determined in response to an operation of the key unit 22 by the user 1 of the portable communication terminal apparatus 20 or the reception of the message (Step S301). That is, whether a display instruction is generated is determined. In case of processes other than the displaying process of the received message (determination of step S301: No), the lighting time of the back light 30 is set to the timer 26 based on a standard lighting value (Step S305).
When the user 1 selects the displaying process of the received message (determination of step S301: Yes), a kind, priority, and length of the message are acquired from the message as a display object which is stored in the memory 21 (Step S302). The kind of the message to be displayed is first determined (Step S303).
When the message to be displayed is the message from the server 10 on the Web site (determination of step S303: No), the color of the back light 30 is changed into a message display color for the message of the Web site
<Desc/Clms Page number 14>
(Step S304). The"lighting time 6f-the back light 30 is set to the timer 26 based on the standard lighting value (Step S305).
On the other hand, when the displayed message is the received E-mail (determination of step S303: Yes), the user first determines the priority of distribution of the received E-mail (Step S306). When the priority of distribution is ordinary (determination of step S306: No), the standard color is used as the back light color. When the priority of distribution is express (determination of step S306: Yes), the data of the color of the back light 30 is changed into a color for the received express mail (Step S307).
After the priority of distribution is confirmed by the display of the received E-mail, the total number of characters to be displayed is calculated from the message length (Step S308). Whether or not the lighting time corresponding to a standard length value is sufficient is determined after the total number of characters to be displayed is calculated (Step S309). When the lighting time corresponding to the standard length value is sufficient (determination of step S309: Yes), the lighting time of the back light 30 is set to the timer 26 based on the standard lighting value as in case of the processing other
<Desc/Clms Page number 15>
than the recei7ved- message (Step 'S310) . When the lighting time corresponding to the standard length value is insufficient (determination of step S309: No), the lighting time of the back light 30 is calculated from the total number of characters to be displayed (Step S311).
As for the method of calculating this lighting time, first, it is supposed that a reading speed of a manuscript by a person is about 300 characters for one minute. Accordingly, The total number of characters to be displayed is calculated. Then, this calculated value is multiplied by a ratio of a standard lighting value of the lighting time of the back light 30 to the above reading speed. The multiplied result is set to the timer 26 as the lighting time of the back light 30 (Step S312).
After the lighting time of the back light 30 is set to the timer 26, the control section 28 issues the display control section 23. Thus, the display control section 24 controls the display section 23 to display the message as the display object (Step S313). The data of the color of the back light 30 corresponding to the displayed message is set to the back light control section 25 (step S314) and the control section 28 issues the back light turn-on instruction to the back
<Desc/Clms Page number 16>
light control-section 25. The beck light control section 25 controls the back light 30 to be turned on in response to the back light turn-on instruction (Step S315).
After the back light 30 is turned on, it is determined whether or not the timer 26 is in time out state (Step S316). When the timer 26 is not in the time out state, the time out state continues to be monitored. When the timer 26 is in the time out (determination of step S316: Yes), it is determined whether a key operation of the operation section 22 is carried out by the user or an event from the peripheral unit interface section 27 occurs after the time out state (Step S317). If there is no key operation by the user or any event from the peripheral unit interface section 27 (determination of step S317: No), the control section 28 issues the back light turnoff instruction to the back light control section 25. The back light control section 25 controls the back light 30 to be turned off in response to the back light turnoff instruction (Step S318).
When there is the operation by the user or the event from the peripheral unit interface section 27 occurs after the time out state (determination of step S317: Yes), the standard lighting value is set to the timer 26 (Step S319).
<Desc/Clms Page number 17>
The'. back light-.control section -215 -controls the back light 30 such that the back light 30 continues to be turned on (Step S314).
In this way, the color and lighting time of the back light 30 of the terminal apparatus are controlled based on the kind, the priority, the length of the received message. Therefore, it is possible to determine what is the received message being displayed. In addition, the back light of the display section 23 can be turned on until the user completes reading of the message, even if the message is long. The unnecessary operation by the user to the terminal apparatus in the reading of the message can be reduced. Also, by dynamically controlling the lighting time of the back light 30, the power consumption of the battery by the display section 23 through the lighting of the back light 30 can be suppressed to the minimum.
Figs. 4A and 4B are flow charts showing the control operation of the back light 30 when the data on the Web site or the data accumulated on the Web site or the mail server is acquired.
First, it is determined whether or not the operation by the user 1 of the portable communication terminal apparatus 20 is an operation for the acquisition of the content data
<Desc/Clms Page number 18>
on the Web sit'a (Step S401). In` case of operations other than the acquisition of the content data on the Web site (determination of step S401: NO), the standard lighting value is set to the timer 26 as the lighting time of the back light 30 (step S404) and then the back light 30 is turned on in response to the back light turn-on instruction from the control section 28 (Step S405).
It is determined whether or not the content data to be acquired is already acquired and stored in the memory 21, when the user operates the acquisition of the content data on the Web site (Step S402).
In case of the already acquired data (determination of step S402: NO), the color of the back light 30 is changed into the color for the content display on the Web site (Step S403). The standard lighting value is set to the timer 26 as the lighting time of the back light 30 (step S404), and then the back light 30 is turned on in response to the back light turn-on instruction from the control section 28 (Step S405).
When the content to be acquired from the Web site is not yet acquired (determination of step S402: YES-), the standard lighting value is
<Desc/Clms Page number 19>
seta to the timer 26 as the lightimg time of the back light 30 (Step S406). After the back light 30 is turned on (step S407), communication for the acquisition of the content from the Web site is started (Step S408). The lighting of the back light 30 at this time depends on the operation by the user for the data acquisition.
The display of another content in the terminal apparatus or the content of another processing other than the content display are displayed based on the communication for the acquisition of the content or the operation by the user. After the back light 30 is turned on in response to the back light turn-on instruction from the control section 28, it is determined whether or not the timer 26 for the back light 30 is in the time out state (Step S409). When the timer 26 is not in the time out state, the time out state continues to be monitored.
When the timer 26 for the back light 30 is in the time out state (determination of step S409: Yes), it is determined whether a key operation of the operation section 22 by the user or an event from peripheral unit interface section 27 occurs after the time out state (Step S410). If there is no key operation of the operation section 22 by the user or the event
<Desc/Clms Page number 20>
from the peripheral unit interface- section 27. (determination of step S410: NO), the back light control section 25 is controlled such that the back light 30 is turned off in response to the back light turnoff instruction from the control section 28 (Step S411).
When the operation by the user or the event from the peripheral unit interface section 27 is confirmed after the time out state (determination of step S410: YES), the standard lighting value is set to the timer 26 for the back light 30 (Step S412). The control of the turning on/off iE performed by the back light control section 25 (Step S413).
It is determined whether or not the terminal apparatus is during the communication processing, after the back light 30 is turned off in response to the back light turnoff instruction from the control section 28 (step S414). If the terminal apparatus is not during communicating (determination of step S414: NO), the processing ends to wait for the next operation by the user. When the terminal apparatus is during communication (determination of step S414: YES), it is determined whether or not the communication continues (Step S415). If the communication is not ended (determination of
<Desc/Clms Page number 21>
step S415: NO)-;- the continuation o-f the communication is monitored. If the communication has ended (determination of step S415: YES), the display color of the back light 30 is set (Step S416). The standard lighting value is set to the timer 26 (Step S417).
After the lighting time of the back light 30 is set to the timer 26, the acquired data as the display object is displayed on the display section 23 (Step S418). The data of the lighting color of the back light 30 corresponding to the display message is notified to the back light control section 25 and the back light 30 is turned on in response to the back light turn-on instruction from the control section 28 (Step S419). The processing after the back light 30 is turned on is the same as the processing from the step S409 to the step S413 described above.
In this way, the back light 30 is turned on when the data is displayed after the data acquisition completes. The back light 30 is turned off during a time from the operation for data acquisition at the link destination displayed in the acquired content to the completion of the data acquisition. Therefore, any unnecessary operation to turn on the back
<Desc/Clms Page number 22>
light 30 agairi'can be reduced.
It should be noted that the lighting color and lighting time of the back light 30 may be dynamically controlled based on the size of the acquired data such as a graphic data and a message data and the kind of the acquired data.
As described above, the portable communication terminal apparatus illustrated is composed c- displav means for displaying data by the turning-on of the back light 30 with a predetermined color, timer means for measuring the lighting time of the back light, and back light control means for controlling the lighting time and lighting color of the back light. The lighting color and lighting time of the back light are controlled in accordance with the kind, priority and length of the data by the back light control means. Therefore, the kind or priority of distribution of a received message can be confirmed without needing any extra operation. Also, it is possible to turn on the back light without needing any extra operation when the acquired content data is displayed.
