Equipped with a digital camera, captures and stores images taken by that camera, and LCDs the images as needed.
Those having a function of displaying on a display have appeared. By using such a mobile phone, it becomes possible to display a favorite image taken by the user as a standby screen, which is convenient for the user. However, in the past, for example, when the face portion of a person is displaced from the center of the screen, it is not possible to move it to the center and display it. There are a lot of requests to be given. One method of responding to such a request is, for example, moving the cursor up, down,
The left and right keys are also used as keys for moving the image,
A method is considered in which the image can be moved to a target position dot by dot.

[0003]

However, in the above method, the up key and the right key must be pressed many times before moving the image to the target position, which takes time and labor. In particular, as the LCD becomes larger, the movable range becomes wider and the number of times of pressing increases, which increases the labor.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example in which an embodiment of a telephone according to the present invention is applied to a mobile telephone having an imaging function (hereinafter, simply referred to as "mobile telephone") will be described. (Internal Configuration of Mobile Phone 1) FIG. 1 is a functional block diagram showing the internal configuration of the mobile phone 1 of the present embodiment.

As shown in FIG. 1, the mobile phone 1 includes a communication unit 2, a voice input unit 3, a voice output unit 4, an image pickup unit 5, a storage unit 6, an operation unit 7, a display unit 8, and a control unit 9. It has a function of using the image captured by the image capturing unit 5 as a standby screen. The communication unit 2 wirelessly communicates with a base station via an antenna and transmits / receives information such as voice and electronic mail.

The voice input unit 3 is composed of a microphone and takes in the voice uttered by the user as a voice signal. The voice output unit 4 is composed of a speaker and outputs the received voice signal of the communication partner. The image pickup unit 5 includes an optical system such as a lens and a CCD.
A solid-state image pickup device such as the above is provided, and an image pickup process for converting an image of a subject into a digital electric signal (image data) and storing the digital electric signal in the storage unit 6 is performed.

The storage unit 6 stores the contents of a management table 90 (see FIG. 9) which will be described later, and also stores the image data and the received information from the image pickup unit 5. Operation part 7
Is provided with a ten-key pad for inputting a telephone number and the like, and is used for a user's transmission / reception operation, a telephone number registration operation, and an instruction to move an image when a standby screen editing process described later is executed.

The display unit 8 is a liquid crystal display (LCD).
And displays the received information and standby screen in the display area. The control unit 9 controls the entire operation of the mobile phone 1, communicates with the base station by a communication process of a known mobile phone, and instructs the imaging unit 5 to perform an imaging process when a shutter button (not shown) is pressed. Let it be done. Also, the standby screen editing process is executed.

(Key Arrangement of Operation Unit 7) FIG.
It is a figure which shows the structure of the key arrange | positioned at. As shown in the figure, the operation unit 7 includes a ten-key 11, a communication key 12, a power key 13, an up key 14, a down key 15, a left key 16, a right key 17, a menu key 18 and an enter key 19. ing.

The ten-key pad 11 is used for inputting a telephone number, a symbol, etc., and each of the keys from "1" to "9" except "5" is used to display the currently displayed image in the standby screen editing process. Also used as a key when moving in units. The menu key 18 is used to display a menu screen for selecting various functions such as telephone number registration and standby screen editing.

The enter key 19 is used when selecting a desired function on the menu screen. The up key 14, the down key 15, the left key 16, and the right key 17 are keys for moving the cursor displayed on the menu screen or the like in the upward direction or the like. It is also used as a key when moving in 1 dot units in the direction. Hereafter, these keys 14 to 17
Are sometimes collectively referred to as scroll keys.

(Contents of Imaging Process) FIG. 3 is a flowchart showing the contents of the imaging process by the imaging unit 5. As shown in the figure, the imaging unit 5 determines whether there is a shooting instruction from the control unit 9, and if there is no shooting instruction (“N” in step S1), waits for the instruction. When there is a shooting instruction (“Y” in step S1), a shooting operation is performed (step S2),
The image data of the captured image is stored in the storage unit 6 (step S3).

The image pickup section 5 picks up an image in a wider range than the displayable area of the display section 8. Therefore, when the picked-up image is used as a standby screen, the entire image is displayed. A portion that does not fit within the area frame, that is, a portion of the captured image corresponding to the size of the display area is displayed as the standby screen. Figure 4
FIG. 4 is a diagram schematically showing a relative size relationship between a captured image and an image displayed as a standby screen. In the figure,
Reference numeral 21 indicates a captured image, 22 indicates a frame of the display area (screen), and the portion within the frame 22 is displayed on the display as a standby screen.

(Details of Standby Screen Editing Process) FIG. 5 is a flow chart showing the contents of the standby screen editing process by the control unit 9. In this process, the user selects "standby screen editing" on the menu screen. Will be executed when
Here, it is assumed that the image data of the captured image shown in FIG. 4 is stored in the storage unit 6 as image data for the standby screen.

As shown in the figure, the control unit 9 first reads the image data from the storage unit 6 and causes the display unit 8 to display the image set as the current standby screen (step S11). FIG. 6 is a diagram showing an example of the screen 50 displayed on the display unit 8. Here, A to I in FIG.
This is a code for indicating each area when the display area of the display unit 8 is virtually equally divided into nine areas in a matrix of 3 × 3 in length and width, and a point 61 indicates a pixel located in the center of the display area. It is shown.

Returning to FIG. 5, in step S12, it is determined whether or not the user has input any key on the operation unit 7. When it is determined that there is no input (“N” in step S12), the input is awaited. When it is determined that there is an input (“Y” in step S12), it is determined whether the pressed key is the enter key 19 (step S13).

If it is determined that the key is not the decision key 19 ("N" in step S13), the process proceeds to step S14.
In step S14, it is determined whether or not the pressed key is any one of the keys "1" to "9" among the ten keys 11. If it is determined that the key is any one of "1" to "9"("Y" in step S14), the area moving process is executed (step S15), and the process returns to step S11.

FIG. 7 is a flow chart showing the contents of the subroutine of the area moving process of step S15. As shown in the figure, first, the control unit 9 determines that the pressed key is "1".
It is determined whether or not it is a key (step S31).
When it is determined that the key is the "1" key ("Y" in step S31), the pixel 61 located in the center of the display area (hereinafter, simply referred to as "screen") of the display unit 8 is located in the center of the area "A". Thus, the image processing for moving the entire image in the upper left direction is performed (step S32), and the process returns to the main routine.

FIG. 8 is a diagram showing an example of a screen displayed after moving the entire image in step S32.
As shown in the figure, the image is moved from the position shown in FIG. 6 so that the pixel 61 is located at the center of the area “A”, and therefore, the image 63 of the flower which is not displayed in FIG. 4) will be displayed in the areas "C", "F" and "I". Here, a memory area for image display is secured in the storage unit 6, and the control unit 9 reads out a portion of the captured image to be displayed on the screen from the stored area and temporarily stores it in the memory area. It is expanded and the expanded image is displayed on the screen. Specifically, the control unit 9
Is a portion of the captured image that should be the display image after the movement, based on the movement direction and the movement distance for moving the pixel 61 from the current center position to the center position of the area “A”,
That is, when the pixel 62 reaches the center of the screen, the range displayed on the screen is determined, and the address on the memory is rewritten for each pixel to develop the image. Note that this process is equivalent to moving the frame 22 shown in FIG. 4 to the lower right by one area.

The reason why the image is moved in the upper left direction when the "1" key is pressed is as follows. That is, normally, the user is most accustomed to using the numeric keypad in addition to remembering it. Therefore,
If the image is moved in the same direction as the position of the “1” key with respect to “5” when the ten-key pad 11 is viewed from the front, when the user wants to move the image to the upper left, It is possible to intuitively determine which key corresponds to the direction, that is, to press the "1" key, and the pressing operation can be performed quickly. By pressing which key, the image can be moved in which direction. This is because it is not necessary to consider that, and the operation becomes easier and easier than the case of using other keys. This is the same when the other keys "2" to "9" other than "5" are pressed, and when the "5" key is the center, the direction in which each key is located moves the image. It matches the direction. The control unit 9 determines which key is pressed to which region the image processing for moving the pixel 61 is performed by referring to the management table stored in advance in the storage unit 6 as the region / key correspondence information.

FIG. 9 is a diagram showing the contents of the management table 90, showing the correspondence between the areas and the ten keys, and showing the divided areas when the display area is virtually divided into areas A to I. The positional relationship and the positional relationship of the numeric keys “1” to “9” keys have positional correlation, that is, the position of each area around the area “E” and the “5” key The positions of the respective keys at the time of are corresponding to each other.

Therefore, for example, for the area "A" located at the upper left of the area "E", the "1" key located at the upper left is assigned to the ten key "5", and therefore the "1" key is pressed. Then, the pixel 61 is displayed in the area “A”.
Moves. Further, for example, for the area “I” located at the lower right of the area “E”, the “9” key located at the lower right of the numeric keypad “5” is assigned, and as described later, the “9” key When is pressed, the image processing is performed so that the pixel 61 moves to the area “I”, and the direction in which each key is located when the “5” key is the center and the moving direction of the image match. It is supposed to do.

Returning to FIG. 7, not the "1" key but the "2"
When it is determined that the key has been pressed (“N” in step S31, “Y” in step S33), the pixel 61 at the center of the screen is located at the center of the area “B” with reference to the contents of the management table 90. As described above, the image is moved upward in units of regions (step S34). In this case, the screen is as shown in FIG. That is, the user can move the image upward by one area by a simple operation of pressing the “2” key once.

When it is determined that the "3" key has been pressed ("N" in step S33 and "Y" in step S35), the pixel 61 is displayed in the area so that the pixel 61 is located at the center of the area "C". The unit is moved in the upper right direction (step S36). That is, the user can move the image by one area in the upper right direction by a simple operation of pressing the “3” key once.

When it is determined that the "4" key has been pressed ("N" in step S35, "Y" in step S37),
The image is moved to the left in the unit of area so that the pixel 61 is located at the center of the area "D" (step S38). That is, the user can move the image leftward by one area by a simple operation of pressing the “4” key once.

When it is determined that the "6" key has been pressed ("N" in step S37, "Y" in step S39), the pixel 61 is displayed in the area so that the pixel 61 is located at the center of the area "F". The unit is moved to the right (step S40). That is, the user can move the image rightward by one area by a simple operation of pressing the “6” key once.

When it is determined that the "7" key has been pressed ("N" in step S39, "Y" in step S41), pixel 6
The image is moved in the lower left direction in units of regions so that 1 is located in the center of the region "G" (step S42). That is, the user can move the image by one area in the lower left direction by a simple operation of pressing the “7” key once. When it is determined that the "8" key has been pressed ("N" in step S41 and "Y" in step S43), the image is moved downward in units of regions so that the pixel 61 is located at the center of the region "H". It is moved (step S44). That is, the user can move the image downward by one area by a simple operation of pressing the “8” key once.

When it is determined that the "9" key has been pressed ("N" in step S43, "Y" in step S45), pixel 6
The image is moved in the lower right direction in units of regions so that 1 is located at the center of the region "I" (step S46). That is, the user can move the image in the lower right direction by one area by a simple operation of pressing the “9” key once. The control unit 9 returns to the main routine after completing the movement processing of the image in unit of area in step S32 and the like. If the "5" key is pressed, the moving process is not performed and the process directly returns.

Returning to FIG. 5, when the routine completes one cycle and the area moving process of step S15 is performed again,
The moving process is performed based on the image displayed at that time. That is, for example, when the image shown in FIG. 8 is currently displayed, the pixel at the center of the current screen is the pixel 62. Therefore, if the "9" key is pressed in this state, the image moves in the lower right direction in units of regions by the process of step S46 so that the pixel 62 is located at the center of the region "I". In this case, as a result, FIG.
The image shown in is displayed on the screen.

When it is determined that the key input in step S14 of FIG. 5 is none of the "1" to "9" keys ("N" in step S14), step S16.
Then, it is determined whether or not it is a scroll key. Here, the scroll keys are the up key 14, the down key 15, the left key 16, and the right key 17, as described above. If it is determined that the key is a scroll key ("Y" in step S16), the process proceeds to step S17 to perform a one-dot moving process.

FIG. 11 is a flow chart showing the contents of a subroutine of the one-dot moving process of step S17. As shown in the figure, the control unit 9 first determines whether or not the input key is the up key 14, and if it is the up key 14 (“Y” in step S51), the entire image is displayed. Then, the image is moved upward by one pixel, that is, by one dot pitch for display (step S52). This is carried out by shifting the address on the memory for each pixel by one pixel and rewriting the data. The frame 22 shown in FIG.
Is substantially the same as moving downward by one pixel. When the up key 14 is input, the display image is moved by one pixel in the upward direction and displayed, which is convenient because the display position of the image can be finely adjusted unlike the area moving process.

On the other hand, if it is determined that the input key is the down key 15 ("N" in step S51, "Y" in step S53), the image is moved downward by one pixel and displayed (step S54). . If it is determined that the left key 16 is pressed (“N” in step S53, “Y” in step S55),
The image is moved by one pixel to the left and displayed (step S56).

When it is determined that the right key 17 is pressed ("N" in step S55), the image is moved rightward by one pixel and displayed (step S57). Control unit 9
Returns to the main routine when the movement process for one dot of the image is completed in step S52 and the like. Returning to FIG. 5, the routine completes one cycle, and step S1 is executed again.
When the 1-dot moving process of 7 is performed, the image moving process is performed based on the image displayed at that time.

When it is determined in step S13 of FIG. 5 that the enter key 19 has been pressed, the current display image is set as the image to be displayed when the standby screen is displayed next (step S18). The process ends.
As described above, in the standby screen editing process of the present embodiment, when the "1" to "9" keys are pressed, the numeric keypad 11 is pressed.
When viewed from the front, the image is moved in a unit of area in the same direction as the direction in which each key is located with respect to the "5" key. Therefore, when the user sees the "5" key as the center, the user simply presses any one of the "1" to "9" keys located in the same direction as the direction in which the user wants to move the image largely. You can move the image largely in the desired direction just by performing various operations, and you do not have to consider which key to press in which direction, so you can perform the pressing operation instantly. There is an effect.

When the scroll key is pressed, the displayed image is moved by one pixel in the direction corresponding to the input key and displayed. Therefore, for example, after the image is moved to a desired position in the region moving process in units of regions, the display position of the image can be finely adjusted in units of one pixel, which is advantageous for the user.

(Modifications) The present invention has been described above based on the embodiments. However, it goes without saying that the present invention is not limited to the above embodiments, and the following modifications are possible. . (1) In the area moving process of the above-described embodiment, the image is moved so that the pixel at the center of the screen is located at the “center” of each area. (One pixel located in the center of the area E or an area having a certain range may be displayed.) Is displayed in a predetermined (not necessarily in the center) position in the area corresponding to the pressed key. You may allow it.

(2) In the above embodiment, the screen is equally divided into nine areas, but the invention is not limited to equal division. For example, if the size of each area is changed according to the aspect ratio of the screen, the amount of movement of the image by one pressing operation can be made larger or smaller than that in the case of equal division. Further, for example, the screen is virtually divided into two parts vertically and horizontally (that is, four parts), and the ten-key "1" is placed in the upper left area, the "3" key is placed in the upper right area, and the "7" key is placed in the lower left area. , Assign the "9" key to the lower right area, for example, "1"
When the key is pressed, the image may be moved in the upper left direction so that the pixel at the center of the display area is located in the upper left area. Also, in the above, "1" for the "5" key
The configuration is such that the direction in which the "9" key is located and the moving direction of the image match, but the present invention is not limited to this, and the image may be moved in the opposite direction, for example. As an example of this case, there is a case where an operation of inputting a portion to be displayed in the center with a ten key is performed. For example, when the image of FIG. 10 is displayed, the operation of pressing the “2” key when moving the petal part in the area B to the area E (center) is performed. Since the image is moved downward in units of regions, the movement direction is reverse to the above.
Therefore, the correspondence between the numeric keypad and the area in this case is
The movement direction is opposite to the above, for example, the area H corresponds to the "2" key and the area I corresponds to the "1" key.

(3) In the above embodiment, the information in which one key is associated with one area (area / key correspondence information) is stored in the storage unit 6 as the management table 90. Is substantially the same as assigning information indicating the moving direction and moving distance of the image to each key, and rewriting the address of each pixel on the memory according to that information. Therefore, the area / key correspondence information can be used as a concept including a content in which each key is associated with information indicating a moving direction and a moving distance of an image when the key is pressed.

(4) In the above embodiment, an example in which the size of the image taken by the image pickup unit 5 is larger than the display area of the display unit 8 as shown in FIG. 4 has been described. Not limited to this, for example, when the size of the captured image is smaller than the screen (display area), that is, when the image enters the screen, it is applied to a configuration in which the image is moved to a desired position. You can also In such an example, the captured image may be displayed away from the center of the screen (no image is displayed in the center of the screen), but in this case, a captured image other than the captured image on the screen may be displayed. The part is treated as the background part of the image, and the part of the screen included in the background is processed so that the image is moved together with the background so that it is located in the area corresponding to the pressed key. . This means that the moving direction and moving distance of the captured image are determined so that the central portion of the screen is located substantially within the area corresponding to the pressed key, and the determined moving direction and moving distance are determined. The address of each pixel of the captured image on the memory is rewritten according to the above, and the image is displayed on the display unit 8.

(5) In the above embodiment, the structure for performing both the region moving process and the 1-dot moving process has been described. However, even if only the region moving process is performed, the image moving operation can be performed easily and easily. It is possible to obtain the effect of being able to do it promptly. (6) In the above-described embodiment, the ten-key "1" to "9" keys are used as the operation keys when moving the image in unit of area, but the keys arranged in a matrix of 3 × 3 in the vertical and horizontal directions are used. As a configuration, for example, a configuration using "4" to "9""0""*""#" keys centering on the "8" key can be used. In addition, in the above area movement processing, when the “5” key is pressed, the through operation is performed (nothing is done). For example, when the “5” key is pressed, the address on the current memory is moved. A process of overwriting may be performed as a later address.

(7) In the above embodiment, an example in which a photographed image is used as a standby screen has been described, but the present invention is not limited to this. For example, the photographed image may be designated as a background or previously designated in the case of calendar display. The present invention can be applied to various scenes such as a case where the image is displayed when an incoming call is received from the other party. (8) In the above embodiment, an example in which the present invention is applied to a mobile phone with an imaging function has been described, but the present invention can be applied to various telephones such as PHS and fixed telephones regardless of such a mobile telephone. In addition, even if the device does not have an imaging function, it is generally used in a telephone having a configuration in which image data is captured from a digital camera or the like as an external device or an image previously stored in a storage unit is read and the image is displayed on a display. Can be applied.

[0046]

As described above, according to the present invention,
The display area of the display is virtually divided into multiple
A storage unit that stores area / key correspondence information in which any one of ten keys is uniquely assigned to each divided area and a key to which the divided area is assigned are operated and displayed on the display. Display control means for moving and displaying the image so that the central portion of the display area is located in the divided area assigned to the key is displayed. As a result, the user can perform the operation of moving the image using the familiar numeric keypad and can greatly move the image with one pressing operation, and the image can be moved quickly with a simple operation. It can be carried out.

Further, the keys to which the divided areas are to be assigned are selected from the ten-key pad so that the positional relationship of the divided areas on the display and the arrangement relationship of the keys assigned to the divided areas have a correlation. Therefore, by pressing the key located in the direction in which the image is desired to be moved, the image can be greatly moved in the desired direction, and the operation becomes easier.

The display area is divided into a matrix of vertical and horizontal 3 × 3, and ten keys 1 to 9 are assigned to each divided area with positional correlation, so that the user can Can be moved in eight directions of up, down, left, right, upper left, upper right, lower left and lower right. Further, since each of the divided areas is formed when the display area is equally divided, the image is moved in units of the divided areas by one key operation. For example, when the display area is a square, , The amount of movement is even in each direction.
