Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 shows a schematic configuration of a rendering algorithm for content display according to an embodiment of the present invention.

Referring to FIG. 1, an apparatus 100 (hereinafter, referred to as a 'content rendering apparatus') for performing a rendering algorithm for content display according to an embodiment of the present invention includes a processing unit 110 and a display unit 120 .

The content rendering apparatus 100 according to an exemplary embodiment of the present invention is an apparatus configured to display content located in a display area on the display unit 120 and to pre-render content located in a potential display area, A personal computer (PC), a navigation device, a personal digital assistant (PDA), a portable media player (PMP), an MP3 player, an electronic dictionary, a computer, and a notebook.

The processing unit 110 obtains the information of the display area by performing an operation such as executing a program or a set of instructions stored in the memory, and based on the display area information, generates a latent display area . Also, the data contents located in the display area are rendered in the memory area and displayed on the display part 120, and the potential display area is rendered free. The processing unit 110 may include at least one processor and a memory, and the plurality of processors may be configured to share memory with each other. A memory stores a program or a set of instructions, and the memory can be a random access memory (RAM), a read-only memory (ROM), a magnetic disk device, an optical disk device, And the like, and the memory area stores data contents that are rendered or pre-rendered.

The display unit 120 displays visual information to the user and displays contents rendered or pre-rendered by the processing unit 110. [ The display unit 120 may include a touch screen display for detecting a touch input.

FIG. 2 is a flowchart of a rendering method for content display according to an exemplary embodiment of the present invention. Referring to FIG. Will be described with reference to Fig. 1 for convenience of explanation.

First, when the content is called on the terminal, the processing unit of the content rendering apparatus renders the data content (first data content) located in the display area of the content in the memory area, displays the rendered data content on the display unit, And detects a potential display area corresponding to an area surrounding the area (S100).

The potential display area detected by the processing unit means an area surrounding the display area that is located in the display area and can be displayed on the screen by moving the data contents or the display area located in the display area by a user's input, Where the user's work input may be a drag, pan, swipe, flicking, or zoom input. The work input means a single non-repeated operation of the user, such as one scroll, and one pinch to zoom using two fingers as described above. The user's work input may be an input to the data content located in the display area or an input to the display area itself, and the data content or the display area located in the display area can be moved by this input.

The potential display area is an area that can be displayed when the user changes the display area through a user's input of a drag or the like in a display area that the user is currently viewing, and can be generally determined to surround the display area, In the case of realizing only vertical or horizontal scrolling, the latent display area has a form located only at the top and bottom or the left and right of the display area. However, when the work input is implemented by a plurality of drag, swipe or flickering inputs, the potential display area can be determined differently from the above. Further, the shape or area of the latent display area described above can be variously modified within the scope of the technical idea of the present invention based on the memory and CPU usage efficiency for the pre-rendering.

When the detection of the potential display area is completed, the processing unit pre-renders the potential display area of the display area in the remaining memory area outside the memory area where the data contents (first data contents) shown in the display area are rendered in the memory area Free rendering) (S110). Here, the pre-rendering of the display area means rendering a latent display area of the data contents shown in the display area, and the latent display area where the pre-rendering is performed may be different according to the area of the memory area. More specifically, the latent display area on which the pre-rendering is performed may be determined differently depending on the area of the remaining memory area. If the area of the latent display area on which the pre-rendering is performed is predetermined, The area of the remaining memory area may be determined.

The processor may perform pre-rendering when idle time such as a CPU or a memory does not perform a separate process, pre-render the process in parallel with other processes, regardless of occurrence of idle time, . ≪ / RTI >

According to an embodiment of the present invention, the memory area includes a first memory area in which data contents in a display area and a data area in the display area are rendered a top and bottom potential display area, and left and right latent display areas of data contents rendered in the first memory area And a second memory area to be rendered, and the second memory area may be composed of two memory areas on the basis of the first memory area.

The division of the memory area is an arbitrary definition for explaining the algorithm of the present invention performed in a virtual space called a memory area. Even if the memory area is composed of a plurality of memory areas, this is a division of processing in which the algorithm is performed. The present invention is not limited to the above-described embodiments.

The upper and lower potential display regions are representations for expressing the relative directions of the first axis and the second axis on the plane with reference to the display region, and the upper and lower potential display regions may be the left and right potential display regions according to the directions of the terminal and the display region. And the left and right latent display areas may be referred to as the upper and lower latent display areas depending on the definition of the vertical and horizontal of the display. Also, according to an embodiment of the present invention, each memory area may include one or more pointers that can identify the direction or position of the rendered potential area in the memory area. The division of the memory area and the role of the pointer will be described in detail later with reference to FIG. 3 to FIG.

When the display area is changed by the input of the user and the changed data contents (second data contents) are displayed, the processing unit calls the pre-rendered data contents (second data contents) from the memory area and displays them on the display unit (S120). At this time, when only a part of the data contents (second data contents) located in the display area changed by the user applying a plurality of inputs or the like is pre-rendered in the memory area, the processing unit pre- And the area that is not pre-rendered may be rendered on the memory area and displayed on the display unit.

The processing unit calls the data content (second data content) from the memory area and displays the data content (S120). After that, the processing unit displays the data area (second data content) (Second pre-rendering) (S130).

The processing unit is adapted to correspond to the data contents (second data contents) located in the post-change display area among the areas in which the potential display area of the data contents (first data contents) located in the display area before change by the user's input is pre- (The first data content) located in the display area before the change among the potential display areas of the data contents (second data contents) located in the display area after the change are called from the memory area (Second pre-rendering) only an area not rendered by the pre-rendering (first pre-rendering). At this time, the processing unit is configured to process the data contents (the first data contents) and the data contents (the first data contents) that are located in the pre-change display area and the data contents (Second pre-rendering) is performed on the corresponding region by deleting the data content in which the region not corresponding to the potential display region of the data content (data content) and the data content (second data content) is rendered. That is, the data content before and after the change and the coinciding area among the potential display areas of the data content are held in the memory area by the user's input of the user, and the data content of the memory area in which the unmatched area is rendered is deleted, Rendering the latent display region of the data contents for the current display region that is not rendered in the remaining memory region generated by re-rendering only the minimum region to perform pre-rendering on the current display region, Rendering can be performed by using the pre-rendering process.

Here, the change of the data content of the memory area means that the data content is newly rendered after the data content of the memory area is deleted, the new data content is overwritten in the area where the data content exists, It includes all things that are replaced with content.

If the user repeatedly performs scrolling or the like to display a non-display area existing outside the latent display area, the procedure of S100 is repeated.

3A to 3C illustrate an embodiment of a rendering method for content display according to an embodiment of the present invention.

3A shows an entire document 310 corresponding to contents called on the terminal, a memory area 300 for rendering contents and a potential display area of contents, and a display part 320 for displaying rendered data contents .

3A, when the electronic document 310 has three pages and one page is located in the display area 311, one page is rendered 305 in the memory area 300, (321) from the terminal 300 and displayed on the display unit 320, that is, the screen of the terminal. At this time, the memory area 300 includes a first memory area 301 having an area capable of displaying two pages, that is, a data area corresponding to two pages, and a first memory area 301 having the same area as the first memory area And the second memory area 302 is formed to the left and right. Here, the memory area divided into a plurality of memory areas is an arbitrary definition for explaining the algorithm of the present invention, which is performed in a virtual space called a memory area as described above. Even if a plurality of memory areas are configured, And it is noted that the division and area of the memory region can be implemented in various forms within the scope of the technical idea of the present invention.

3A, the data contents of the display area 311 are rendered 305 in the first memory area 301 and the latent display area 312 is displayed in the remaining memory area of the first memory area 301. [ The data contents of the two-page area corresponding to the pre-rendering (306) are pre-rendered. At this time, since the area corresponding to the horizontal axis of the content is displayed on the display unit 320, the second memory area 302 is not used, and the position of the uppermost one of the rendered data contents is And is indicated by the first pointer 303.

FIG. 3B shows a case where data contents corresponding to two pages of the entire document 310 are displayed in the display area 313 by a user's input, in performing a rendering algorithm for content display according to an exemplary embodiment of the present invention The memory area 300, and the display unit 320 shown in FIG.

3B, when the display area is changed from page 1 to page 2, the processing unit calls (322) the data content of the two pages, which is the current display area, from the memory area 300 and displays it on the display unit 320 And performs a pre-rendering 307 on the potential display area of the data contents. At this time, among the areas corresponding to the potential display areas 314 and 315 of the display area 313 in the entire document 310, the area 315 not rendered in the memory area is pre-rendered 307, The rendered region 314 does not perform rendering separately. The region where the pre-rendering 307 is performed as shown in FIG. 3A is the same as that of FIG. 3A except for the data content of the current display region 313 and the potential display region 314, and 315, that is, the upper portion of one page, the data content rendered in the corresponding region is deleted, and a new pre-rendering 307 is performed on the corresponding region.

When the display area is changed and the latent display area is changed, the rendering values for the previous display area and the latent display area are retained when they are used again, and are deleted if they are not used. As the display area is changed at the deleted position, the data content that needs to be newly rendered is rendered. Accordingly, although the order of the data content rendered in the memory area 300 and the information contained in the entire document 310 do not match, the position of the uppermost one of the rendered data contents is the first pointer 303 And the position of the lowest area is indicated by the second pointer 304 to distinguish the direction or position of the rendered data content on the memory area 300. [

By dividing the position of the data contents by the pointer, when the order of the data contents rendered on the memory area does not match the entire document, the data contents corresponding to the display area can be efficiently called, By predetermining the location to be performed, the data content can be efficiently pre-rendered.

3C shows a state in which the potential display areas 317 and 318 are rendered in the memory area 300 when the display area 313 shown in FIG. 3B is changed to another display area 316 by a user's input. do.

3C, in the same way as in FIG. 3B, the display area is changed to change the latent display area, unnecessary parts of the previous latent display area are deleted, and new pre-rendering 308 is performed in the corresponding area, The positions of the areas corresponding to the top of the rendered data contents are displayed by the first pointer 303 while the positions of the rendered data contents and the information included in the entire document 310 do not coincide with each other, The position of the corresponding area is indicated by the second pointer 304 to distinguish the direction or position of the rendered data content on the memory area 300. [

3A to 3C, when the display area is changed, the changed data content located in the display area and the area coinciding with the latent display area of the changed data content, out of the areas rendered in the memory area, The data content of the memory area in which the inconsistent area is rendered is deleted and the latent display area of the changed data contents is pre-rendered in the corresponding area so that only the minimum area is re-rendered and the pre- And perform pre-rendering using a limited memory area.
