2 is a block diagram of a portable electronic device for controlling display of a partial image according to an exemplary embodiment of the present invention, and FIG. 10 is a partial image of a portable electronic device scrolling a raw image according to an exemplary embodiment of the present invention. It is an exemplary diagram showing an example of displaying.

2, the portable electronic device 100 according to the preferred embodiment of the present invention includes an input module 110, a memory 120, a display module 130, and a control module 140. Hereinafter, a mobile phone of the portable electronic device 100 will be described as an example, but all portable electronic devices 100 including a display means such as a PDA and a digital camera can be equally applied. Will be.

The input module 110 is a means for receiving an input signal such as an image display command, an image enlargement command, or a scroll signal according to a partial image display of an enlarged image from a user. Button input means such as a key button and a mouse function It may be provided with a mouse means for. When the user moves the portable electronic device 100 using the optical sensor, the mouse means may generate an input signal according to the movement. Accordingly, the portable electronic device 100 may perform an operation such as scrolling an image according to an input signal caused by the movement. Here, the scroll is not a concept of “rolling up”, which is a dictionary meaning, but a concept of selecting (or searching) some images to be displayed on the screen among the raw images stored in the memory 120.

The memory 120 is a storage means for storing image data, an OSD image, a mouse pointer image, and the like. The image data stored in the memory 120 is extracted by the control module 140 to be displayed through the display module 130. Can be. Hereinafter, the image data stored in the memory 120 will be described as an example of decoded data. Of course, the raw image may be encoded in a compressed format such as a JPEF format and stored in a specific storage space of the memory 120 or a separate storage means, and the image data to be displayed through the display module 130 may be decoded in advance. May be stored in a specific space of 120.

 It will be apparent to those skilled in the art that the memory 120 may be equally applicable to all of the currently developed or future storage means, such as Dynamic Random Access Memory (DRAM) and Synchronous DRAM (SDRAM).

The display module 130 is a means for displaying image data, and may be, for example, a liquid crystal such as a liquid crystal display (LCD). Hereinafter, the LCD will be described as an example of the display module 130 for convenience of description.

The control module 140 controls the memory 120 and the display module 130 to extract the image data stored in the memory 120 and to be displayed through the display module 130. In particular, the control module 140 controls the input module 110. The input module 110, the memory 120, and the display module 130 are controlled to extract certain image data from the raw image data according to a specific control signal input through the display module 130. In addition, when a magnification command for an image is input, the control module 140 enlarges the image data and stores the image data in the memory 120. For example, if the arbitrary image data is an image of 10 * 10 size, the control module 140 converts the image data into 20 * 20 size image and stores the image data in the memory 120 when the 4x magnification command is input. Control each component.

Here, the magnification of the image to be displayed on the screen is to enlarge the corresponding image data stored in the memory 120 and to store the image data in the memory 120, and the portable electronic device 100 displays the display module from the enlarged image data stored in the memory 120. Some image data matching the screen size of 130 is extracted and displayed. Since magnification of an image such as 2 times or 3 times is not related to the main features of the present invention, detailed description thereof will be omitted. However, the present invention is characterized in that when the enlarged image or the raw image itself is larger than the screen size, only part of image data of a specific region is extracted and displayed from the corresponding image. The description focuses on controlling the display of some areas of the image larger than the screen size.

When the image itself to be displayed is an image larger than the screen size, an image reduced to correspond to the screen size is initially displayed, and a part of the original image may be displayed according to an enlargement command from the user. Alternatively, as described above, a portion of the raw image may be directly enlarged. Of course, if the raw image is larger than the screen size to be displayed, it is natural that some images may be displayed without a separate magnification command.

The portable electronic device 100 according to an embodiment of the present invention may enlarge an original image and display some of the original image. Hereinafter, for convenience of explanation, the original electronic image stored in the memory 120 is larger than the original screen size. It will be described with an example.

In addition, when a scroll signal for some of the displayed images among the raw images stored in the memory 120 is input through the input module 110, the control module 140 recognizes some images corresponding to the scroll signals (according to the scroll signal). Each of the above-mentioned components is controlled to calculate the shifted coordinate values to recognize some images according to the corresponding coordinates, to extract the corresponding image data from the memory 120 and to output the image data through the display module 130.

Referring to FIG. 10, the portable electronic device 100 is provided with an optical sensor 102 for a mouse on the opposite side of the display module 130 so that the user may move the portable electronic device 100 to display the original image 1000. You can scroll the area. Of course, the screen may be scrolled using a specific button (for example, a direction button, etc.) of the keypad of the input module 110, or a mouse may be used. When using a mouse, moving the mouse to the edge of the screen may scroll some images of the raw image along the direction of the mouse.

The user may move the mouse pointer by using a direction button or the like, or may move the mouse pointer by moving the portable electronic device 100 itself using the optical sensor 102 described above. Of course, when using the optical sensor 102, in order to distinguish the movement of the mouse pointer and the movement of the screen scroll, each mode must be set first. For example, in a state in which a specific button (for example, a mouse button provided separately) is pressed, the mouse function may be set to a mouse mode, and the screen scroll function mode may be performed in the non-pressed state. When a part of an arbitrary raw image is displayed, a method of setting the position of the mouse pointer will be described with reference to the related drawing (FIG. 8).

The control module 140 may include a multimedia processor that processes multimedia related tasks such as an image. Hereinafter, a configuration of a multimedia processor for controlling the display of some images according to an exemplary embodiment of the present invention will be described.

3 is a block diagram illustrating a multimedia processor according to an exemplary embodiment of the present invention, and FIGS. 4 and 5 are coordinate recognition processes of some images for displaying some images of a raw image according to an exemplary embodiment of the present invention. 6 is a table illustrating a register and a function of a multimedia processor according to an exemplary embodiment of the present invention, and FIG. 11 is a part of a raw image of the multimedia processor according to an exemplary embodiment of the present invention. It is a figure for explaining the method of displaying an image.

Referring to FIG. 3, the multimedia processor 300 according to an exemplary embodiment of the present invention may include a coordinate generator 310, an image data processor 320, an OSD processor 330, a mouse pointer processor 340, and an overlayer ( 350 and the display module interface unit 360.

The coordinate generator 310 generates a function of each coordinate of the image to be displayed on the screen. That is, the coordinate generation unit 310 generates and provides coordinates so that the image data processing unit 320, the OSD processing unit 330, and the mouse pointer processing unit 340 display an image corresponding to each corresponding position, thereby providing each image data. It performs a function of a counter for the operations of the processor 320, the OSD processor 330, and the mouse pointer processor 340. For convenience of understanding, for example, the coordinates of the entire screen area to be displayed are (0,0) to (20,20), and the area of the image image to be displayed by the image data processor 320 is (0, From 0) to (18,20), the area of the OSD image to be displayed by the OSD processing unit 330 is from (19,0) to (20,20), of the mouse image to be displayed by the mouse pointer processing unit 340. Assume that the area is from (10, 10) to (12, 12). In this case, the coordinate generator 310 sequentially generates coordinates of (0,0) to (20,20) according to the entire screen area, respectively, so that the image data processor 320, the OSD processor 330, and the mouse pointer processor ( 340 provides corresponding coordinates, such as the respective coordinates described above, respectively. Accordingly, when the image data processor 320, the OSD processor 330, and the mouse pointer processor 340 receive coordinates corresponding to the image data processor 320, the OSD processor 330, and the mouse pointer processor 340, the image data processor 320 extracts the corresponding image data and provides the image data to the overlayer 350.

The image data processor 320 calculates an address of the memory 120 corresponding to the coordinates generated and received by the coordinate generator 310 and extracts the image data from the calculated address. Upon receiving the base coordinates (eg, (0,0)) from the initial coordinate generation unit 310, the stored base address (the multimedia processor 300 includes a register for storing the base address, 6) and extract the corresponding image data. Thereafter, an address corresponding to the coordinate received from the coordinate generator 310 is calculated using the base address, and image data corresponding to the calculated address is extracted from the memory 120. The extracted image data may be temporarily stored in a FIFO (Fist In First Out) storage means such as a provided queue and then provided to the overlayer 350.

As illustrated in FIG. 6, the image data processor 320 may include a register for storing a base address, a register having information about a horizontal size of an original image stored in the memory 120, and a size of some images to be displayed on a screen, that is, an LCD. Three registers may be included, such as a register having size information about a horizontal size and a vertical size of a screen.

Hereinafter, a process of extracting image data based on coordinates by the portable electronic device 100 according to an exemplary embodiment of the present invention will be described with reference to FIGS. 4 and 5.

Referring to FIG. 4, a description of each term is illustrated, and it can be seen that image data of some images to be displayed on a screen is located in a partial region of the memory 120. Here, the "memory screen" shown in the drawing means a space of the memory 120 in which the original raw image is stored, and is used for convenience of description.

An algorithm according to an embodiment for extracting image data of a part of an image as illustrated in FIG. 4 is illustrated in FIG. 5. That is, the image data processing unit 320 uses the algorithm shown in FIG. 5 to coordinate from (0,0) to (L_hsize, L_vsize) from the coordinate generation unit 310 according to the size (horizontal and vertical length) of the screen. The values are sequentially input (for example, from left to right and top to bottom), and the corresponding image data is extracted from the memory 120 by calculating an address according to the corresponding coordinate value.

Although not shown in the drawing, the control module 140 of FIG. 2 or the multimedia processor 300 of FIG. 3 may include a base address setting unit for setting a base address, and the base address setting unit may be implemented in a software form.

The base address setting unit calculates a variation value of the x and y coordinate values corresponding to the input scroll signal and applies the same to change the base address to set the base address. For example, when the base address of the image currently displayed on the screen is A, and the x value increases by 3 as the scroll is performed, the base address may be calculated as A + 3. Recognizing a coordinate change value according to a scroll signal through a mouse, a keypad, and the like is still used in a portable terminal or a computer such as a mobile phone, and thus a detailed description thereof will be omitted. The changed base address is updated and stored in the corresponding register of the multimedia processor 300 (see FIG. 6).

The OSD processor 330 functions to extract the OSD image (reference numeral 104 of FIG. 10) to be displayed on the screen from the memory 120 or a separate storage means and provide the OSD image to the overlayer 350. That is, the OSD processor 330 also receives coordinate values from the coordinate generator 310 and extracts image data according to a corresponding OSD image as the corresponding coordinates of a predetermined position are received. The OSD processor 330 may also extract the corresponding OSD image from the memory 120 using the same method as the algorithm shown in FIG. 5.

The OSD processor 330 may include an OSD_0 base address for storing base address information storing image data according to an OSD image as illustrated in FIG. 6, and a reference point at which an OSD image starts on a screen (for example, an upper left corner of an OSD image). ) May include three registers, such as OSD_0 offset having information about) and OSD_0 size having information about the size of the OSD image.

The mouse pointer processing unit 340 functions to display a mouse pointer (eg, an arrow-shaped image displayed on the screen) on the screen. As illustrated in FIG. 6, the mouse pointer processing unit 340 may include three registers of OSD_1 base address, OSD_1 offset, and OSD_1 size. The mouse pointer may be positioned at a screen position corresponding to the algorithm shown in FIG. 5. Can be displayed. A method of setting the reference point at which the mouse pointer is located by the mouse pointer processing unit 340 will be described later with reference to related drawings (FIGS. 7 and 8).

The overlayer 350 overlays, or synthesizes, image data received from the image data processor 320, the OSD processor 330, and the mouse pointer processor 340 to provide the display module interface 360 with an overlay. . Since the overlay function of the plurality of image data is a technique still used today, a detailed description thereof will be omitted.

The display module interface unit 360 functions to display the image data received from the overlay unit 350 by the display module 130.

As described above, the multimedia processor 300 according to an exemplary embodiment of the present invention extracts some image data 1120 of the raw image data 1110 stored in the memory 120 and displays the image immediately as shown in FIG. 11. It is displayed through the module interface unit 360. Therefore, the portable electronic device 100 according to the present invention can reduce the bandwidth of the bus BUS and reduce the amount of clock used because the amount of the multimedia processor 300 can be reduced. Therefore, there is an effect that can lower the heat generation and power consumption. Here, the microprocessor 1100 illustrated in the drawing may include respective components of the multimedia processor 300 except for the display module interface unit 360 according to an exemplary embodiment of the present invention. That is, each component of the multimedia processor does not necessarily need to be implemented in hardware, and it will be understood that it may be implemented in software such as a program.

FIG. 7 is an exemplary view illustrating an image displayed on a screen and a mouse pointer according to the image in a whole image according to an exemplary embodiment of the present invention, and FIG. 8 illustrates a mouse according to an exemplary embodiment of the present invention. A diagram illustrating an algorithm for calculating a reference point at which a pointer is located.

Referring to FIG. 7, an original image 700 stored in the portable electronic device 100 and the memory 120 is illustrated. The user may scroll some images displayed on the screen by moving the portable electronic device 100. As shown by reference numeral 710, the mouse pointer is preferably set to be positioned at the center of the screen for the convenience of the user. If an image of a corner portion of the raw image 700 is displayed on the screen as indicated by reference numeral 720 or 730, the mouse pointer may be set to be displayed at a corresponding position.

An algorithm for setting the coordinates of the reference point of the mouse pointer (for example, the tip of the arrow, which is the upper left corner of the mouse pointer) is shown in FIG. 8.

Referring to FIG. 8, the pointer coordinate x on the screen of the memory 120 is the X coordinate of the point where the mouse pointer is positioned before the image is enlarged. When the screen is enlarged and a partial image is displayed, a corresponding x ′ coordinate is generated. Set as the X coordinate of the mouse pointer. In the same manner, the Y coordinate of the mouse pointer according to the partial image display of the enlarged image may be set.

9 is a flowchart illustrating a process of performing a scroll function while a portable electronic device displays a partial image of a raw image according to an exemplary embodiment of the present invention.

Referring to FIG. 9, in operation 910, the portable electronic device 100 receives a scroll signal. As described above, the scroll signal may be input through a mouse, an optical sensor, a key button, or the like.

In operation 920, the portable electronic device 100 calculates a variation value of the x and y coordinates corresponding to the scroll signal.

In operation 930, the portable electronic device 100 calculates a base address of some images to be displayed on the screen by using the calculated variation value and a previously stored previous base address. Since the method of calculating the base address of some images has been described above, a detailed description thereof will be omitted.

In operation 940, the portable electronic device 100 extracts the partial image, the corresponding OSD image, and the mouse pointer image stored in the memory 120 by using the calculated base address of the partial image and outputs the same through the display module 130. Even when the screen is scrolled, the position where the OSD image and the mouse pointer image are displayed hardly changes, and thus the base addresses of the OSD image and the mouse pointer image do not change. Of course, when the OSD image or the mouse pointer image changes as the screen scrolls, each base address according to each variation value may be calculated.

The method of the present invention as described above may be implemented in a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

As described above, according to the present invention, it is possible to provide an apparatus for controlling the display of some images that do not require a separate memory space for displaying a portion of the raw image and a method of controlling the same.
