Background Art
[2] The development of wireless communication has made a wide and universal use of mobile phones such as hand-held phones or PDA (Personal Digital Assistant) phones. When user turns on the mobile phone, a standby-display appears on a display screen of the mobile phone. The information displayed in the standby-display basically contains time and date, etc. The user can variously select standby-display at a menu screen of the mobile phone or can change the same by downloading. In order to change the previous standby-display to a new standby-display composed of different picture, a key-button operation must be accompanied. So, the process for changing the standby- display becomes inconvenient and the time required for the process becomes long. Here, the change of the standby-display means to totally replacing the previous standby-display with another standby-display, not to partially modifying parts of the previous standby-display. Therefore, a conventional method for changing the standby- display has an inherent limit in view of variety of picture. Disclosure of Invention Technical Problem

[15] A more complete appreciation of the invention, and many of the attendant advantages thereof, will be better appreciated by reference to the following detailed description.
[16] Fig. 1 is a schematic drawing showing a device for modifying a standby-display according to an embodiment of the present invention. A device 10 for modifying a standby-display of the mobile phone (hereinafter which is referred to as the modification device 10) may be installed within the mobile phone 9 or mounted outside of the mobile phone 9 and electrically connected to the mobile phone 9. In the present embodiment, the modification device 10 is installed in the mobile phone 9. Referring to Fig. 1, the modification device 10 comprises an operation button 18 for starting the
standby-display modification mode, a posture change data generator 11 and 12 for producing digital signal representing a posture change of the mobile phone upon the push of the operation button, a standby-display database 15 where a plurality of standby-display data corresponding to the posture change of the mobile phone are stored, a display screen 14 for displaying the standby-display data and a controller 13 receiving the digital signal from the posture change data generator 11 and 12 and then accessing the standby-display database 15, for producing a standby-display data corresponding to the posture change of the mobile phone 9 on the display screen 14. The standby-display database 15 is a standby-display provider for providing the modified standby-display to the display screen 14 under the command of the controller 13. And posture change data generator 11 and 12 includes a posture change detector 11 for producing analogue signal corresponding to the posture change of the mobile phone upon the push of the operation button 18 and a digital signal converter 12 for classifying the analogue signal into several groups and for converting the classified analogue signal to digital signal.
[17] The analogue signal representing the posture change, which is detected at the posture change detector 11, includes a motion direction and a slant degree of the mobile phone 9 by rotation thereof. As an example of the posture change detector 11, an accelerometer may be used. In Fig. 1, since the output from the posture change detector 11 is analogue signal, the digital signal converter 12 is needed. However, when the posture change detector for producing pulse width modulation signal is used, the digital signal converter 12 is not needed.
[18] As described above, a plurality of standby-display data mapped to the data representing the posture change of the mobile phone are stored in the standby-display database 15. Each of the stored standby-display data is composed of background image data and/or character image data. The character image data indicates image shown only on a part of the display screen 14 such as an animation character while the background image data indicates image shown on the whole of the display screen 14. By the modification device 10, is modified at least one of the background image data and the character image data of a reference standby-display in response to the posture change of the mobile phone. Wherein the reference standby-display is a standby-display firstly appeared on the display screen 14 of the mobile phone just after the push of the operation button 18. For example, the stored standby-display data may include the standby-display data in which only character image data is shifted in a direction according to the motion direction of the mobile phone and the standby-display data in which the background image data itself or color thereof is changed according to the motion of the mobile phone, etc. The user can produce the modified standby-display using a digital camera phone or can download the same from a remote standby-display
provider. Also, the user can set a rule for modifying the character image and color of the background image of the reference standby-display and so on forth in response to the motion of the mobile phone, and then edit the standby-display. The edition of the standby-display data may be carried out on the web or LAN (Local Area Network). [19] A schematic view of a modification device of the mobile phone capable of editing the standby-display on the web or LAN using the posture change of the mobile phone, is illustrated in Fig. 2. In Fig. 1 and Fig. 2, the same numerals are assigned to the same things. Referring to Fig. 2, a modification device 10a comprises the operation button 18, a posture change detector 1 la, the display screen 14, a controller 13a for controlling the display screen 14, a server 17 connected via internet or LAN to the controller 13a for providing standby-display service, and an item button 19 for use in a selection of modification item to change the character image data or the background image data of the standby-display. In Fig. 2, the posture change detector 11a produces pulse width modulation signal (digital signal). So, the digital signal converter is not needed. The operation button 18, the posture change detector 11a, the display screen 14, the controller 13a and the item button 19 are equipped within the mobile phone 9a and the server 17 is prepared on the web or the LAN. The server 17 is a standby- display provider for providing the modified standby-display to the display screen 14 under the control of the controller 13 a.
[20] If the command signal for starting the standby-display modification mode is inputted through the operation button 18, the posture change detector 11a operates to produces digital signal representing the posture change of the mobile phone 9a. At this time, when the user presses the item button 19, the modification items such as a change of the character image, and a change of background image and color thereof and so forth, are displayed on the display screen 14. Then the user selects one modification item using a direction button (or arrow button which is not shown) with the item button 19. A table where the item code corresponding to the selected modification item is mapped to the modification item, is prepared in the controller 13a. The controller 13a finds the item code corresponding to the selected modification item and receives the digital signal representing the posture change of the mobile phone 9a, to produce an editing data for editing the reference standby-display. The server 17 includes a reference standby-display database 17a and an editor 17b for editing the reference standby-display data in response to the editing data provided from the controller 13a. At the reference standby-display database 17a, is stored the reference standby-display data that is set regardless of the posture change of the mobile phone 9a.
[21] With reference to Fig. 1, Fig. 3, Fig. 4 and Fig. 5, an operation of the modification device in the mobile phone 9 according to one embodiment of the present invention will be explained in detail. Fig. 3 is a schematic drawing showing a mobile phone in
which an accelerometer is mounted. Fig. 4 illustrates examples of a modification of the standby-display according to the motion of the mobile phone. Fig. 5 is a flow chart for showing a method for modifying the standby-display of the mobile phone.
[22] The numerals 1 lb, 23 and 29 of Fig.3 are corresponded to the numerals 11, 14 and 9 of Fig. 1. Referring to Fig. 3, a display screen 23 is formed at a upper part 21 of a folder- type mobile phone 29, and a plurality of function buttons (not shown) including an operation button (18 in Fig. 1) for starting the standby-display modification mode is formed at a lower part 22 of the folder-type mobile phone 29. Also, the modification device 10 of Fig. 1 is installed in the mobile phone 29. The accelerometer 1 lb employed as the posture change detector 11 of Fig. 1 is installed in the lower part 22 of the mobile phone 29 and measures the posture change of the mobile phone 29. In Fig.3, 2-axis inertia sensor 1 lb is used as an example of the accelerometer 1 lb. The 2-axiz inertia sensor 1 lb consists of X-axis inertia sensor and Y-axis inertia sensor. The X-axis inertia sensor produces slant value of the mobile phone 29 when the mobile phone 29rotates around Y-axis in clockwise or counter-clockwise direction, and the Y- axis inertia sensor produces slant value of the mobile phone 29 when the mobile phone 29 rotates around X-axis in clockwise or counter-clockwise direction. When the mobile phone 29 rotates around Y-axis, the 2-axiz inertia sensor 1 lb produces an acceleration changed according to the slant of the mobile phone 29. The changed acceleration is represented by the sinuous function of the gravitational acceleration (G). In detail, if the mobile phone 29 rotates around Y-axis in clockwise direction, the X-axis inertia sensor produces positive acceleration and then if the slant value of the mobile phone 29 reaches 90-degree, that is +X axis coincides with gravitational acceleration, the X-axis inertia sensor produces +1G. If the mobile phone 29 rotates around Y-axis in counterclockwise direction, the X-axis inertia sensor produces negative acceleration and then if the slant value of the mobile phone 29 reaches 90-degree, that is -X axis coincides with gravitational acceleration, the X-axis inertia sensor produces -IG. Accordingly, X-axis inertia sensor produces value between -IG and +1G as the mobile phone 29 rotates around Y-axis. Similarly, Y-axis inertia sensor produces value between -IG and + 1G as the mobile phone 29 rotates around X-axis.
[23] Referring to Fig. 5, if the operation button 18 is pressed, the accelerometer 1 lb consisting of X-axis inertia sensor and Y-axis inertia sensor operates and produces analogue signal representing the posture change of the mobile phone 29 (step SI). The acceleration measured just after the input of the operation button 18 is data representing a reference posture (or initial posture) of the mobile phone 29. After a given time passes by, the accelerometer 1 lb measures acceleration according to the motion (rotation) of the mobile phone 29. Then the accelerometer 1 lb calculates the difference between two data and finally produces analogue signal representing the posture change
of the mobile phone 29 resulted from the rotation. Thereafter, the output of the accelerometer 1 lb is classified into several groups and the analogue signal included in each group is converted into corresponding digital signal, at the digital signal converter 12 (step S2). In case where the accelerometer lib produces digital signal, the step S2 is not needed. One example of the classification and digital conversion is shown in a following table 1.
[24] Table 1
[25] As shown in table 1, the analogue acceleration (A) representing the posture change of the mobile phone 29 is classified into seven groups and data of each group is converted into 3bits data with respect to each axis. Therefore, 6bits data for representing the posture change of the mobile phone 29 is produced from the digital signal converter 12. When the analogue output of the X-axis inertia sensor and the analogue output of the Y-axis inertia sensor are between -0.1G = A < +0.1 G, the output of the digital signal converter 12 is 6bits of "000000". At this time, the controller 13 does not access the standby-display database 15 and the standby-display is not modified. Accordingly, the digital signal converter 12 can produce 36 kinds of 6bits data for representing the effective posture change of the mobile phone 29. For using the above 6bits data as a factor for modifying the standby-display, 36 kinds of standby-display must be prepared. In the standby-display database 15, 36 kinds of different standby- displays are mapped to 36 kinds of 6bits data and stored therein.
[26] The modified standby-displays may be formed by shifting only the character image data of the reference standby-display by a distance corresponding to a slant value of the mobile phone 29 in a rotation direction of the mobile phone 29. One example of the above-mentioned modified standby-displays is illustrated in Fig. 4. Referring to Fig. 4, there is the reference standby-display at a left side. When the mobile phone 29 rotates around Y-axis by about 30-degree in the clockwise direction, the X-axis inertia sensor 1 lb produces about +0.5G and then the digital signal converter 12 produces 3bits of "101". At this time, the mobile phone 29 does not rotate around X-axis or rotate by - 0.1G = A < +0.1G. So, the digital signal converter 12 produces 6bits of "101000". The controller 13 receives the 6bits of "101000" accesses the standby-display database 15 and extracts a standby-display mapped to the 6bits of "101000" (step S3). The extracted standby-display is displayed on the display screen 23 (step S4) so that the
reference standby-display is modified as shown in a center of Fig. 4. In the modified standby-display, the character image is shifted in a right direction as compared with the reference standby-display.
[27] Similarly, when the mobile phone 29 rotates around Y-axis by about 30-degree in the counter-clockwise direction, the X-axis sensor 1 lb produces about -0.5G and then the digital signal converter 12 produces 3bits of "010" with respect to the X-axis. At this time, the mobile phone 29 does not rotate around X-axis or rotate by -0. IG = A < +0.1G. So, the digital signal converter 12 produces 6bits of "010000". The controller 13 receives the 6bits of "010000" accesses the standby-display database 15 and extracts a standby-display mapped to the 6bits of "010000". The extracted standby- display is displayed on the display screen 23 so that the reference standby-display is modified as shown in a right side of Fig. 4. In the modified standby-display at the right side, the character image is shifted in a left direction as compared with the reference standby-display. In brief, when the mobile phone 29 rotates around Y-axis in the clockwise direction, the character image of the standby-display moves in the right direction, and when the mobile phone 29 rotates around Y-axis in the counterclockwise direction, the character image of the standby-display moves in the left direction. Similarly, when the mobile phone 29 rotates around X-axis in the clockwise direction, the character image of the standby-display moves in the forward direction, and when the mobile phone 29 rotates around X-axis in the counter-clockwise direction, the character image of the standby-display moves in the backward direction.
[28] Now, with reference to Fig. 2, Fig. 3, Fig. 4 and Fig. 6, an operation of the modification device according to another embodiment of the present invention will be explained in detail. The numeral 1 lb of Fig.3 is corresponded to the numerals 1 la of Fig. 2. Fig. 6 is a flow chart for showing a method for modifying the standby-display of the mobile phone 29 through the web or the LAN. The mobile phone 29 is connected to the server 17 of Fig. 2 via the internet or the LAN (step S5). The user presses the operation button 18 and then the 2-axis accelerometer 1 la of the posture change detector operates. The 2-axis accelerometer 1 la produces digital signal. Also, the user pushes the item button 19 and then the modification items such as a change of the character image, and a change of background image and color thereof and so forth are displayed on the display screen 14. Then the user selects one modification item using a direction button (or arrow button which is not shown) with the item button 19. A table in which the item code corresponding to the selected modification item is mapped to the modification item, is prepared in the controller 13a. An example of the item code mapped to the item to be modified (modification item) is shown in a following table 2. The user can variously set or modify the item code, modification item and the relation therebetween as needed.
[29] Table 2
![Figure imgf000011_0001](https://patentimages.storage.googleapis.com/98/eb/5b/0c5409a77f0852/imgf000011_0001.png)
[30] The controller 13a receives the output of the 2-axis accelerometer 11a and item code, to produce an editing data for use in an edition of the standby-display (step S7). Thereafter the editing data is transmitted to the server 17. The editing part 17b of the server 17 receives the editing data to modify the reference standby-display in the reference standby-display database 17a. The modified standby-display is displayed on the display screen 14 under the control of the controller 13a (step S8). In detail, the controller 13a finds item code corresponding to the selected modification item and receives the digital signal representing the posture change of the mobile phone 9a, thereby producing the editing data composed of 2bits in the table 2 and 6bits in the table 1. The relation between each of 6bits data of the table 1 and each item code in the table 2 is set and stored in the editing part 17b, and then is informed on the display screen 14. Therefore, the user can catch how to move the mobile phone in order to modify the standby-display as he wishes. For example, if the user would like to move the character image in the standby-display, he selects the modification item of "motion of character image" by using the item button 19 with the direction button. The item code " 10" corresponding to the item of "motion of character image" is searched at the controller 13a. Also, the user rotates the mobile phone 19 around Y-axis by about 30-degree in clockwise direction and the 2-axis accelerometer 1 la produces 6bits of "101000". The controller 13a finds the item code "10" and receives 6bits of "101000" to generate the editing data of "10101000". Accordingly, the modified standby-display as shown in the center of Fig. 4, is displayed. It is known to the skilled person who is pertinent to a digital image processing art that the technique for shifting the character image of the standby-display by some distance in response to the editing data, and thus the explanation thereof is omitted.
[31] In the above description, only the motion of the character image is explained as an example of a factor for the standby-display modification. However, the present invention is not limited thereto, and the color of background image, the background image itself and the character image itself could be modified by the slant change of the mobile phone. Therefore, the user variously modifies the standby-display of the mobile phone by adjusting the slant of the mobile phone, without the button treatment.
[32] Additional advantages and modifications will readily occur to those skilled in the art. Accordingly, various modifications may be made without departing from the spirit
or scope of the general inventive concept as defined by the appended claims and their equivalents.
