They are connected to each other via a synchronous bus 51.

When the call end and the power key are turned on by the operation of the user, the power supply circuit unit 41 supplies power to each unit from the battery pack to start the mobile phone 10 in an operable state. .

The mobile phone 10 has a CPU, a ROM and an R
Under the control of the main control unit 40 composed of AM or the like, the audio signal collected by the microphone 21 in the audio communication mode is converted into digital audio data by the audio codec 49, and this is subjected to spectrum spread processing by the modulation / demodulation circuit unit 48, After the digital-analog conversion processing and the frequency conversion processing are performed by the transmission / reception circuit unit 53, the data is transmitted via the antenna 14.

The mobile phone 10 amplifies the received signal received by the antenna 14 in the voice communication mode, performs a frequency conversion process and an analog-to-digital conversion process, and performs a spectrum despreading process in the modulation / demodulation circuit unit 48. After being converted into an analog audio signal, this is output via the speaker 17.

Further, when transmitting an e-mail in the data communication mode, the cellular phone 10 transmits the text data of the e-mail input by operating the operation keys 19 and the jog dial 22 to the main control unit 40 via the operation input control unit 42. To send to.

The main control section 40 performs spread spectrum processing on the text data in the modulation / demodulation circuit section 48,

On the other hand, when receiving an e-mail in the data communication mode, the portable telephone 10
After the received signal received from the base station 2 is despread by the modulation / demodulation circuit unit 48 to restore the original text data, it is displayed as an e-mail on the liquid crystal display 18 via the LCD control unit 45. Thereafter, the mobile phone 10 can also record the received e-mail on the memory stick 30 via the recording / reproducing unit 52 according to the operation of the user.

On the other hand, when transmitting image data in the data communication mode, the mobile phone 10 supplies image data picked up by the CCD camera 16 to the image encoder 43 via the camera interface unit 44.

By the way, when the mobile phone 10 does not transmit the image data, the mobile phone 10 transmits the image data picked up by the CCD camera 16 to the camera interface 44 and the LCD controller 4.
It is also possible to display the information directly on the liquid crystal display 18 via the display 5.

The image encoder 43 converts the image data supplied from the CCD camera 16 into, for example, an MPEG (Moving Pic).
The data is converted into coded image data by compression coding according to a predetermined coding method such as a frame expert group 2), and is transmitted to the demultiplexing unit 47. At this time, the mobile phone 10 simultaneously transmits the voice collected by the microphone 21 during the imaging by the CCD camera 16 to the demultiplexing unit 47 as digital voice data via the voice codec 49.

The demultiplexing section 47 multiplexes the coded image data supplied from the image encoder 43 and the audio data supplied from the audio codec 49 in a predetermined system, and multiplexes the resulting multiplexed data into a modulation / demodulation circuit section. The signal is subjected to spread spectrum processing at 48 and subjected to digital / analog conversion processing and frequency conversion processing at the transmission / reception circuit unit 53, and then transmitted via the antenna 14.

On the other hand, when the mobile phone 10 receives data of a moving image file linked to a simple homepage or the like in the data communication mode, for example,
The spectrum demodulation circuit 48 performs spectrum despread processing on the received signal received from the base station 2 via the base station 2.

The demultiplexer 47 separates the multiplexed data into coded image data and audio data,
The coded image data is supplied to the image decoder 46 via the synchronization bus 51 and the audio data is supplied to the audio codec 49.

The image decoder 46 generates reproduced moving image data by decoding the encoded image data by a decoding method corresponding to a predetermined encoding method such as MPEG2.
This is sent to the liquid crystal display 18 via the LCD control unit 45.
, Thereby displaying, for example, moving image data included in the moving image file linked to the simplified homepage.

At this time, the audio codec 49 simultaneously converts the audio data into an analog audio signal and supplies the analog audio signal to the speaker 17, whereby, for example, the audio data included in the moving image file linked to the simplified homepage is converted. Will be played.

In this case, similarly to the case of the electronic mail, the portable telephone 10 can record the data linked to the received simple homepage or the like on the memory stick 30 via the recording / reproducing unit 52 by the operation of the user. .

As described above, the mobile phone 10 can perform not only the function as a telephone but also the transmission and reception of mail, the browsing of a homepage, and the like. When performing a process such as selecting a desired function from such various functions or searching for a homepage to be browsed, it is important for the mobile phone 10 having a small display screen to provide an easy-to-use graphic user interface. .

Here, a program related to the graphic user interface of the mobile phone 10 will be described. FIG. 6 is a diagram illustrating a program used for a graphic interface that controls the display of icons displayed on the liquid crystal display 18. The program of the graphic user interface is stored in a ROM (not shown) in the main control unit 40, and by reading out the stored program, processing described later is executed.

The physical device 61 shown in FIG. 6 means, for example, a memory area necessary for generating an image according to an application on the liquid crystal display 18. The graphic device interface (GDI) 62 generates on the liquid crystal display 18 image components necessary for generating the above-described application image, such as a cursor image, a scroll bar, a window frame, and an image input from the CCD camera 16. In this case, a program required for the above, that is, a logical device is associated with a memory area in which the logical device is recorded.

These logical devices are stored, for example, in a ROM (not shown) built in the main control unit 40 as object data for menu selection. For the application image, a logical device and its positional relationship are specified by the GUI, and the graphic interface 62 is displayed.
Is formed as bitmap data on a memory (on the physical device 61) through the interface, and is repeatedly read out and displayed on the liquid crystal display 18, whereby an application image is generated on the liquid crystal display 18.

The external operator 63 is the operation key 19 and the jog dial 22. When an event such as rotating the jog dial 22 to move the image (for example, a cursor) of the logic device displayed on the liquid crystal display 18 or keeping the jog dial 22 pressed is generated, the address of the above-described memory area is changed. And the point on the screen of the liquid crystal display 18, for example, the direction and how much the jog dial 22 has been rotated can be determined by the device handler (device driver) 6.
4, the device handler 64 detects that the dialog manager 6
Communication with 5 starts.

The dialog manager 65 interacts with the application program 66 based on the detected information. The application program 66 is created according to the purpose of use of the graphic user interface. The application image displayed on the liquid crystal display 18 and the processing procedure corresponding to an input event from the external operator 63 are determined in detail. It is a program. When the application 66 and the dialog manager 65 determine the configuration of the application image in response to the input event, the application 66 informs the display operation program 67 of the result.

The display calculation program 67 is for calculating and determining the display method of the response application image. For example, the image elements generated before the event input and which have not changed are displayed as they are. The image element whose position has been changed specifies the display position by calculation, and if a new logical device is required, the device is read from the memory area where the device is recorded, and the application image of the response image is stored in the memory described above. It instructs the GDI 62 to form.

According to the above configuration, the liquid crystal display performs a series of operations such as displaying a selection item as described later, moving the cursor with the rotation of the jog dial 22, and selecting and determining an icon by pressing the jog dial 22. 18 to form a graphical interface with the operator.

Next, FIG. 7 shows a functional block diagram relating to the display of icons provided by the graphic interface as described above. The icons here refer to the phonebook, register new phone numbers in the phonebook,
It symbolizes functions such as connecting to the Internet and reading mail.

The icon selection detection unit 71 includes an operation input control unit 42 for inputting data from the jog dial 22,
The main control unit 40 determines what kind of input has been made. The storage unit 72 stores data related to the selected icon detected by the icon selection detection unit 71, and is configured by a storage element (not shown) or the memory stick 30 provided in the main control unit 40.

The frequency calculation section 73 calculates the number of times of use (the number of times of selection) of each icon according to the data stored in the storage section 72. Based on the calculation result, the icon size calculation unit 74 calculates the size of each of the icons to be displayed on the liquid crystal display 18.
Further, the icon array calculation unit 75 calculates how to arrange each icon according to the size of each icon determined by the icon size calculation unit 74. The calculation result by the icon array calculation unit 75 is output to the storage unit 72 and stored. That is, the data stored in the storage unit 72 is updated.

Frequency calculation section 73, icon size calculation section 7
4 and the icon array calculation unit 75
Or the frequency calculation unit 73
The main control unit 40, the icon size calculation unit 74, and the icon array calculation unit 75 may be configured by the LED control unit 45, respectively. Further, the application program 66 in FIG. 6 may be configured as software.

The data related to the display of the icon stored in the storage unit 72 is read out when the display of the icon is instructed, supplied to the LED control unit 45, and stored in the LE control unit.
The D control unit 45 controls the display of the icons displayed on the liquid crystal display 18 based on the supplied data.

The operation of each function of such a functional block diagram relating to the display of icons will be described with reference to the flowchart of FIG. In step S1, when the event that a predetermined icon is selected is detected by the icon selection detection unit 71, the processing of the flowchart illustrated in FIG. 8 is started. The event that a predetermined icon is selected is, for example, an operation in which the user operates the jog dial 22, positions the cursor on one of a plurality of icons displayed on the liquid crystal display 18, and presses the icon. Is determined to have been performed.

It is to be noted that as a premise for an event that an icon is selected, when an icon is selected last time, each function of the functional block diagram shown in FIG. By the execution of the processing, an icon is displayed based on the data stored in the storage unit 72.

In step S2, the storage unit 72 stores (updates) the total number of times of selection of the icon selected in step S1. In step S3, the frequency calculation unit 73 calculates a frequency for each icon. For example, when ten icons are displayed on the liquid crystal display 18, the frequency is calculated for each of the ten icons.

Specifically, when the number of times selected for each icon is stored in the storage unit 72, the frequency calculation unit 7
3 performs processing such as reading the data stored in the storage unit 72 and rearranging the data in descending order of the number of selections.
In the case where the selected date and time are stored in association with each icon in the storage unit 72, a total of the selected date and time is calculated (calculation of use frequency is performed),
For example, they are rearranged in descending order of the total result.

When the accumulated total is stored in the storage unit 72 and the frequency calculation unit 73 only reads out data from the storage unit 72, the processing of the frequency calculation unit 73 is simplified, and therefore, it can be omitted as a function. It is. When the date and time of use for each icon is stored in the storage unit 72 in association with each other, for example, an icon that has a large cumulative number but has not been used recently can be subjected to the subsequent processing by setting the cumulative number to 0. Thus, icons can be displayed in a form that meets the latest user needs.

In step S 4, the icon size calculator 74 calculates the size of the display area of each icon on the liquid crystal display 18. Icon size calculator 74
Performs calculation such that the display size of each icon is determined in proportion to the calculation result from the frequency calculation unit 73. That is, the size of each icon is calculated so that the most frequent icon is displayed in the largest size.

Then, in step S5, the icon arrangement calculating section 75 determines the arrangement of the icons which are considered to be the most optimal (the most likely to be seen by the user) according to the size of each icon calculated by the icon size calculating section 74. Is calculated. In step S6, the calculation result (data) by the icon array calculation unit 75 is output to the storage unit 72 and stored. The data stored in the storage unit 72 in this manner is output to the LED control unit 45 the next time an icon display is instructed. LED control unit 4
5 controls the display of the liquid crystal display 18 based on the input data so that each icon is displayed in a predetermined layout at a predetermined size.

Next, the icons displayed on the liquid crystal display 18 by the above-described processing will be specifically described. In the following description, it is assumed that the number of icons displayed on the liquid crystal display 18 is nine. FIG. 9 is a diagram showing a display example of the icons on the liquid crystal display 18. The display example shown in FIG. 9A is an initial state, in which nine icons A to I are displayed in the same size. The initial state is stored in the storage unit 72 (FIG. 7).
In this state, data on the size and display position of each icon calculated based on the number of times each icon is selected is not stored.

The user repeatedly performs an operation of selecting an icon several times from the initial display state as shown in FIG. 9 (A), and each time, in each function of the functional block diagram shown in FIG. The display is controlled in accordance with the data stored in the storage unit 72 by performing the processes described with reference to the flowchart of FIG.
This is the display state shown in FIG.

In the display state shown in FIG. 9B, the icon A is displayed in the largest area because the icon A is selected most frequently. The icon B and the icon C are displayed in a region next to the icon A because the number of times of selection is substantially the same. The icons D to I are displayed in regions of the same size because they have the same number of selections (or the number of selections is 0).

In this display state, when the operation of selecting an icon is repeatedly performed by the user, the total number of times of selection of each icon becomes different. For example, as shown in FIG. 9C. Display state. The display state shown in FIG.
Is displayed in the largest area because it is used more frequently than other icons. Further, the icon B and the icon C are displayed in a region next to the icon A because the icon B and the icon C are used frequently after the icon A. The icons D to F are displayed in small areas because the icons A to I are the least frequently used.

The icons DF are shown in FIG.
In the display example shown in (B), the images are displayed horizontally, but in FIG. 9C, they are displayed vertically. In this way, according to the frequency of use, not only the area is displayed small, but also the location is moved.

Next, the determination of the size of the area to be displayed (the processing of step S4 in FIG. 8) will be described using specific numerical values as an example. Here, the description will be made on the assumption that the size of the liquid crystal display 18 is 120 × 120 dots and the dot pitch is about 0.2 mm. In the liquid crystal display 18 having such a size, the minimum size of the icon that can be visually recognized by the user is about 16 × 16 dots.

Here, when icons having the smallest size are displayed vertically or horizontally, 7.5 icons are displayed side by side when one icon is in the unit of 16 × 16 dots. It is possible to However, since 0.5 icons, that is, icons having a size of 8 × 8 dots, are hard to visually recognize and cannot be used substantially, it is not necessary to provide them as spaces for displaying nothing (wasteful). ), The minimum size of the icons is set to 20 × 20 dots instead of 16 × 16 dots, so that six icons can be displayed vertically or horizontally.

The icon of 20 × 20 dots represents about 2.8% (= (2
0 × 20) / (120 × 120)). In this way, the icons that are hardly used are consequently displayed in an area of about 2.8% of the screen.

On the other hand, the most used icons are displayed in a large area, but may be displayed on the entire liquid crystal display 18 and the other icons may not be displayed at all. Then, in order to select another icon, it is necessary to perform an operation for displaying the other icon, which is troublesome and troublesome. Therefore, all icons are displayed, and the largest size for displaying the most used icons in the largest area is considered.

An example is shown in which nine icons are displayed on the liquid crystal display 18 at one time, and only one icon is used, so that the number of times of the most selected accumulation increases. Will be explained. When nine icons are displayed on one screen, the arrangement of the icons is as shown in FIG.
It is considered that it is most appropriate to arrange and display three rows and three rows as shown in FIG.

As described above, when the minimum size of one icon is set to 20 × 20 dots, for example, as shown in FIG. They can be displayed side by side in the bottom row. Of the remaining three icons, one icon (icon A) is displayed in a large area, and how to display the other two icons (icon B and icon C) is a problem. As shown in FIG. 10A, when the largest icon A is displayed in the first row as a rectangular shape, the remaining two icons are displayed in the second row.

The two icons displayed in the second row both have a vertical width of 20 dots and a horizontal width of 120 dots. The number of dots may be 60 dots at a time, or may be divided by different numbers of dots such as 54 dots and 46 dots as shown in FIG.

As shown in FIG. 10A, the icon A

In the following formulas, a to d are not percentage values but values before multiplication by 100.

The coordinates of the four corners of the icon A are
(0,0), (x1,0), (y1, x1), and (0, y1). The coordinates of the four corners of the icon B are (x1, 0), (X, 0), (X, y1), and (x1, y1), respectively. The coordinates of the four corners of icon C are
(0, y1), (x2, y1), (x2,
Y) and (0, Y). The coordinates of the four corners of the icon D are (x2, y1), (X, y1),
(X, Y) and (x2, Y).

As described above, when the coordinates are set, the following equations (1) to (5) hold. x1y1 / XY = p (1) (X-x1) y1 / XY = q (2) x2 (Y-y1) / XY = r (3) (X-x2) (Y −y1) / XY = s (4) p + q + r + s = 1 (5)

From the equations (1) and (2), x1 = pX / (p + q) (6) y1 = (p + q) Y (7) Equations (3), (5) and From the equation (7), x2 = rX / (r + s) (8) By using the equations (6) to (8), the X coordinate x
Since 1, X coordinate x2 and Y coordinate y1 can be obtained, it is possible to calculate the display areas of the icons A to D.

Next, a case where nine icons are displayed on one screen will be described with reference to FIG. Also in FIG. 12, the size of the liquid crystal display 18 is X × Y dots. In the display area of the liquid crystal display 18, the ratio of the display area of the icon A is a%, the percentage of the display area of the icon B is b%, the percentage of the display area of the icon C is c%, and the percentage of the icon D is The proportion occupied by the display area is d%, and the proportion occupied by the display area of the icon E is e
%, The percentage of the display area of the icon F is f%, the percentage of the display area of the icon G is g%, the percentage of the display area of the icon H is h%, and the percentage of the display area of the icon I is i%. And Note that, in the following equations, a to i are not percentage values but values before multiplication by 100.

The coordinates of the four corners of the icon A are respectively
(0,0), (x1,0), (x1, y1), and (0, y1). The coordinates of the four corners of the icon B are (x1, 0), (x2, 0), (x2, y1),
And (x1, y1). The coordinates of the four corners of the icon C are (x2, 0), (X, 0), (X, y
1) and (x2, y1). The coordinates of the four corners of the icon D are (0, y1), (x3, y1),
(X3, y2) and (0, y2).

The coordinates of the four corners of the icon E are
(X3, y1), (x4, y1), (x4, y2), and (x3, y2). The coordinates of the four corners of the icon F are (x4, y1), (X, y1), (X, y1), respectively.
y2), and (x4, y2). Icon G 4
The coordinates of the corner are (0, y2), (x3, y
2), (x5, Y), and (0, Y). The coordinates of the four corners of the icon H are (x5, y2), (x
6, y2), (x6, Y), and (x5, Y). The coordinates of the four corners of the icon I are (x6, y
2), (X, y2), (X, Y), and (x6, Y)
It is.

When the coordinates are set in this manner, the following equations (9) to (18) x1y1 / XY = a (9) (x2-x1) y1 / XY = b (10) X-x2) y1 / XY = c (11) x3 (y2-y1) / XY = d (12) (x4-x3) (y2-y1) / XY = e (13) (X-x4) (y2-y1) / XY = f (14) x5 (Y-y2) / XY = g (15) (x6-x5) (Y-y2) / XY = h (16) (X-x6) (Y-y2) / XY = I (17) a + b + c + d + e + f + g + h + i = 1 (18)

Equations (9), (10) and (11)
Y1 = (a + b + c) Y (19) x1 = aX / (a + b + c) (20) x2 = (a + b) X / (a + b + c) (21)

Equations (12), (13) and (1)
From 4), y2 = (a + b + c + d + e + f) Y (22) x3 = dX / (d + e + f) (23) x4 = (d + e) X / (d + e + f) (24)

Equations (15), (16) and (1)
From 8), x5 = gX / (g + h + i) (25) x6 = (g + h) X / (g + h + i) (26)

By using equations (19) to (26), the X coordinates x1, x2, x3, x4, x5, x6, Y
Since the coordinates y1 and y2 can be obtained respectively,
Each display area of the icons A to I can be calculated.

The size of the icon is calculated as described above. As a result, as shown in FIG. 13A, for example, the icon A is １ ／ of the entire display area of the liquid crystal display 18. If you occupy more space,
Further, taking into account the display areas of the icons B and C, when only the icons A to C occupy an area equal to or more than ２, the icons B and C may be displayed vertically. Conceivable.

When the icon is displayed in a portrait orientation, the design is generally deformed, and it is often difficult to see (decision is difficult). To prevent this, FIG.
As shown in FIG. 3 (B), it is better to display the icon in a shape close to a square. In other words, x1> X
/ 2, y1> Y / 2, and (x2-x1) or (X
If -x2) is equal to or smaller than X / 4, the display area of the icon becomes a vertically long display area. In such a case, the following consideration is performed, and the icon is displayed as shown in FIG. Make each icon a square shape.

That is, considering the icons B and C, the following equation (27) holds. b: c = y3: (y1-y3) (27) From the equation (27), the following equation (28) is derived. y3 = (b × y1) / (b + c) (28) The Y coordinate y3 can be calculated from equation (28), and this equation (28)
Can be used together with equations (19) to (26) to calculate each coordinate.

As described above, if the size of the display area of each icon displayed on the liquid crystal display 18 is changed depending on the frequency of use, icons that are frequently used are large and icons that are rarely used are small. As a result, it is easier to search for a desired icon from the displayed icons. Therefore, the selection of the icon becomes simple and easy.
