Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal, and more specifically to a mobile communication terminal having two or more state modes with different power consumption.
[0002]
[Prior art]
Many recent mobile communication terminals have not only a voice communication function but also an Internet access function and a PIM function (personal information management function).
However, power consumption when accessing the Internet and voice communication simultaneously is very large, and a mobile communication terminal with a limited battery capacity cannot be used for a long time.
Therefore, paying attention to the fact that the power consumption is greatly different between when using the above function and when not using it, a method of switching the state mode so as to reduce the power supplied from the battery when the above function is not used Has been taken.
FIG. 6 is a diagram illustrating an example of mode transition of the mobile communication terminal. Here, the mobile communication terminal has three state modes such as an active mode (401), a standby mode (405), and a partial mode (409) in descending order of power consumption (supply power).
[0003]
In the active mode (401), all functions including a voice communication function, an Internet access function, and a PIM function (personal information management function) can be used. When the [Cancel] key is pressed in the active mode (401) (403), the mode shifts to the standby mode (405).
In the standby mode (405), none of the voice communication function, the Internet access function, and the PIM function (personal information management function) are used. Therefore, the power consumption is smaller than that in the active mode (401). In the standby mode (405), the screen saver can be activated (can be prevented from being activated).
When the standby mode (405) state continues for a certain period of time, the mode automatically shifts to the partial mode (409) (411). In the partial mode (409), as in the standby mode (405), none of the voice communication function, the Internet access function, and the PIM function (personal information management function) are used. Further, if the screen saver is activated in the standby mode (405), it is also terminated. Therefore, the power consumption in the partial mode (409) is the smallest among the three state modes.
Note that, in both the standby mode (405) and the partial mode (409), when there is an incoming call or when there is some action by the user, the mode shifts to the active mode (401).
[0004]
[Problems to be solved by the invention]
However, when shifting from the standby mode to the partial mode, the conventional mobile communication terminal has little change in the movement of the display display image.
An object of the present invention is to provide a mobile communication terminal that reduces a screen saver image on a display in a time stepwise manner when shifting from a standby mode to a partial mode.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention reduces the ratio of the screen saver image in the entire display in time step when shifting from the standby mode to the partial mode. Provided is a mobile communication terminal characterized by comprising control means for controlling the transition to the partial mode to be completed when the ratio reaches 0 percent.
Furthermore, the present invention provides a mobile communication terminal characterized by comprising control means for controlling a character, a character other than a character, and an illustration displayed on a display to have an animation operation.

Finally, FIG. 5 shows an example of display display.
[0007]
As shown in FIG. 1, the mobile communication terminal according to the present invention includes a main body control unit 100 that controls the operation of the main body and a connection unit 110 that controls transmission and reception operations.
The main body control unit 100 is provided with a hardware driver 2, a speaker / microphone 3, a liquid crystal display LCD 4, a keyboard 5, and a flash memory 6 with the MCU 1 as the center. A user IF 7 is provided in the flash memory 6. MCU1 is a microcontroller that controls the operation of the main body. The MCU 1 controls the speaker / microphone 3, the LCD 4, and the keyboard 5 via the hardware driver 2.
The keyboard 5 includes function keys for performing various settings in addition to a numeric keypad for inputting a telephone number. Information input by the keyboard 5 is displayed on the LCD 4. When the speaker / microphone 3 receives a call from the other party or calls from the other party to complete the connection operation, the speaker / microphone 3 outputs the other party's voice or inputs his / her own voice.
The MCU 1 is also connected to the flash memory 6 and has a user IF 7 storing therein a program and information related to the user interface.
The connection unit 110 includes an RF module 11 and digital signal processors 12 and 13 (DSP1 and DSP2). The RF module 11 includes a transmission / reception circuit. The digital signal processors 12 and 13 apply sound and image processing to the signal output from the RF module 11 and the signal input to the RF module 11.
[0008]
A numeric keypad 213 is arranged in front of the mobile communication terminal in FIG. The numeric keypad 213 is used not only for inputting a telephone number but also for inputting characters. An LCD 209 is disposed on the front surface of the mobile communication terminal. The LCD 209 displays information such as the telephone number of the other party and the stored name of the other party, as well as the e-mail being created and the received e-mail.
Reference numeral 203 denotes a soft key, which can be key-locked in a predetermined key procedure. The key lock is to disable the key input operation in order to prevent the key input from being mistakenly performed when it is put in a pocket or a bag. When releasing the key lock, the combination of the soft key 203 and the numeric keypad 213 is pressed.
Reference numeral 211 denotes a navigation key, which shifts the state mode from the partial mode to the active mode or from the standby mode to the active mode according to a predetermined key procedure (for example, pressing the combination with the soft key 203). Can do.
When the Call key 205 is pressed, a call is made to the telephone number input with the numeric keypad 213 and the telephone number called from the telephone directory. When the Cancel key 207 is pressed, the active mode is shifted to the standby mode.
[0009]
FIG. 3 is a diagram showing a display example of the LCD 209 when the state mode transitions from the active mode (501) → standby mode (503) → partial (505). A mobile communication terminal to which the present invention is applied has a color display function.
In the active mode (501) of FIG. 3, the terminal user is in a call state, and the name of the other party (Mayumi Yamamoto in FIG. 3) and the image of the other party are displayed on the LCD 209. The display content including the image of the other party can be displayed in color. In the active mode (501), the display content is displayed in 4096 colors.
When the Cancel key is pressed after the call is finished, the standby mode (503) is entered. In the standby mode (503), the voice communication function, the Internet access function, and the PIM function (personal information management function) are not used. Therefore, the power consumption of the entire terminal is smaller than that in the active mode (501). .
[0010]
Further, color display is possible even in the standby mode (503). In FIG. 3, it is assumed that 4096 colors are displayed in the same manner as in the active mode (501). In FIG. 3, the screen saver is activated in the standby mode (503), but it can be set not to be activated.
When the standby mode (503) continues for a certain time, the mode automatically shifts to the partial mode (505). In the partial mode (505), the voice communication function, the Internet access function, and the PIM function (personal information management function) are not used, and the screen saver is also terminated. Therefore, the power consumption is the smallest among the three state modes (501 to 505). Further, in order to reduce power consumption, it is assumed that color display is performed with 8 colors in the partial mode (505).
[0011]
In the present invention, a mobile communication terminal is proposed in which the screen saver image is not erased at one time, but is reduced in time stepwise when the standby mode (503) is shifted to the partial mode (505). The screen transition diagram at that time is shown in FIG.
A screen 601 is an example of a screen saver image displayed on the LCD 209 during the standby mode (503).
When a certain time (t seconds) elapses after the standby mode (503) is entered, the proportion of the screen saver image in the entire LCD 209 decreases, and the display shown on the screen 603 is obtained. In the screen 603 of FIG. 4, the screen saver image in the lower quarter of the LCD 209 disappears, and the ratio of the screen saver image to the entire LCD 209 is about 75%. .
When the time t seconds elapse after the screen 603 is entered, the screen 605 is entered, and the ratio of the screen saver image in the entire LCD 209 is further reduced. The ratio of the screen saver image on the screen 605 is half (about 37%) as compared with that on the screen 603.
When time t seconds elapse from the state of the screen 605, the screen 607 is reached, and the screen saver image is completely disappeared from the LCD 209. That is, the ratio of the screen saver image in the entire LCD 209 is 0%.
At this point, the transition from the standby mode (503) to the partial mode (505) is completed.
[0012]
FIG. 5 is a display example of the LCD 209 during the partial mode (505). On the upper part 305 of the LCD 209, in addition to the numbers or illustrations representing the antenna reception strength, the current time, and the remaining battery level, a character “out of service 303” that appears when the terminal is out of service and an icon 301 are displayed.
The mobile communication terminal to which the present invention is applied can rotate or vibrate the icon 301. Furthermore, characters (including characters) such as the out-of-service area 303 can be moved up and down, left and right, or moved. These animation operations can prevent the LCD 209 from being burned.
Such an animation operation can also be applied to the standby mode (503) in which the screen saver is not activated.
[0013]
Although the embodiment of the present invention has been described above, the present invention is not limited to the above description, and for example, it is possible to change the reduction rate of the screen saver image when shifting from the standby mode to the partial mode.
In the above description, image processing is performed so that the screen saver image disappears from the bottom to the top of the LCD, but processing may be performed so that the screen saver image disappears from the top to the bottom. You may process so that it may disappear toward a part. A plurality of other forms are possible, and this embodiment is an example.
[0014]
