Accordingly, the elements of the device may be installed as one chip or a plurality of chips according to a design of the device. 
       FIG. 2  is a flowchart illustrating a method for providing contents according to an exemplary embodiment of the present invention. Respective steps of  FIG. 2  to be described below may be performed by the digital device of the present invention. That is, the processor  110  of the digital device  100  may control the respective steps of  FIG. 2  based on the control command of the content control module  200  of the digital device  100  illustrated in  FIG. 1 . 
     First, the digital device of the present invention may display a first target area of the content (S 210 ). In the exemplary embodiment of the present invention, the digital device sets at least a partial area of the content as a target area and displays the target area onto a display unit. In this case, the target area becomes an area of the content which is presently displayed in the display unit. In the exemplary embodiment of the present invention, the target area of the content may be defined as various exemplary embodiments. For example, the contents of the present invention may include a plurality of display pages, that is, a plurality of photographs, a plurality of document pages, a plurality of home screens, and the like. In this case, the target area of the content may include at least one of the plurality of display pages included in the contents. Further, according to another exemplary embodiment of the present invention, the target area of the contents may be predetermined map content or a partial area of a specific photograph. Hereinafter, in the present invention, the target area is used as a concept including various types of areas in the content that are displayed in the display unit. 
     Meanwhile, in the exemplary embodiment of the present invention, when the contents include the plurality of display pages, the plurality of display pages may be arrayed in the contents in a specific sequence. The sequence array includes all of a 1D array, a 2D array, and a 3D array. When the contents are sequenced in the 1D array, another display page included in the contents may be present in the direction of at least one of previous and next (alternatively, left and right) pages of the specific display page. Further, when the contents are sequenced in the 2D array, another display page included in the contents may be present in at least one direction of up, down, left, and right directions of a specific display page and a combination thereof. Similarly, when the contents are sequenced in the 3D array, another display page included in the contents may be present in at least one direction of forward, backward, up, down, left, and right directions of a specific display page and a combination thereto. However, the array direction described herein is a predetermined array direction for describing the sequence array of the present invention and may be modified as various exemplary embodiments. 
     Next, the digital device of the present invention receives a user input for changing the target area of the contents (S 220 ). In the exemplary embodiment of the present invention, the user input includes a scroll input of the contents, a page turning input of the contents, and the like. A means for the user input includes a keyboard direction key input, a mouse click input, a mouse click and drag input, a sliding touch input, a button touch input, a gesture input, and the like and besides, includes various means for changing the display area of the contents. The user input may indicate a direction in which the target area is changed in the contents. The digital device may change the target area based on direction information included in the user input. 
     Meanwhile, according to another exemplary embodiment of the present invention, the user input may be received by an external sensor unit connected to the digital device. The external sensor unit may detect the user input and transfer the detected result to the digital device. That is, in the exemplary embodiment of the present invention, the user input may be detected by the sensor unit in the digital device detected by the external sensor unit to be transferred to the digital device. 
     Next, the digital device of the present invention determines whether a speed of the user input of changing the target area is equal to or higher than a predetermined speed (S 230 ). In the exemplary embodiment of the present invention, the speed of the user input may be defined by various methods. According to the exemplary embodiment, the speed of the user input may be decided based on the number of input times of the user input per hour. In this case, the digital device may measure a speed of a corresponding user input based on the number of repetition times of the same user input for a predetermined time. According to another exemplary embodiment, the speed of the user input may be decided based on a change amount of the target area per hour. For example, when a user scrolls the contents by using a sliding touch input (alternatively, the mouse click and drag input), as the speed of sliding (dragging) performed in the corresponding user input is higher, the target area of the contents may be rapidly changed. In this case, the digital device may measure the speed of the user input based on a movement and change speed of the target area by the user input. 
     When the speed of the user input is lower than the predetermined speed in step S 230 , the digital device changes the target area of the contents to a second target area (S 242 ). In this case, the second target area is an area different from the first target area and may be an area having the same size as the first target area. According to the exemplary embodiment, the second target area may be an area neighboring to the first target area and may be an area positioned in a direction indicated by the user input based on the position of the first target area. 
     Meanwhile, when the speed of the user input is equal to or higher than the predetermined speed in step S 230 , the digital device changes the target area of the contents to the increased second target area (S 240 ). In this case, the increased second target area is an area different from the first target area and may be an area larger than the first target area. According to the exemplary embodiment, the increased second target area includes an area neighboring to the first target area and may include an area positioned in the direction indicated by the user input based on the position of the first target area. Further, the increased second target area may be an area including more display pages than the first target area. 
     Next, the digital device of the present invention displays the target area changed through step S 240  or S 242  (S 250 ). According to the exemplary embodiment of the present invention, the digital device may adjust displaying the corresponding target area based on the size of the changed target area. That is, the digital device may reduce a display scale of the second target area when the target area is changed to the increased second target area through step S 240 . According to another exemplary embodiment of the present invention, the digital device may provide at least one window for displaying the target area on the display unit. The digital device may display different areas of the contents through a plurality of windows. According to the exemplary embodiment of the present invention, the digital device may display the first target area in step S 210  in a first window mode and the second target area increased through step S 240  in a second window mode. In this case, the second window mode provides more windows than the first window mode onto the display unit together. A detailed exemplary embodiment of steps S 240  to S 250  will be described in detail with reference to  FIGS. 3 to 9  below. 
       FIGS. 3 to 9  illustrate a detailed exemplary embodiment in which the digital device  100  according to the exemplary embodiment of the present invention receives user inputs  10  and  12  to change the target area of the content and displays the changed target area to correspond thereto. In  FIGS. 3 to 9 , the digital device  100  of the present invention receives a sliding touch input of the user as the user inputs  10  and  12 . In this case, the user input  10  represents a general user input and the user input  12  represents a user input having a speed which is equal to or higher than a predetermined value. The user input  12  may include a sliding touch input of the user performed at the predetermined number of times for a predetermined time or an input of the user to rapidly perform sliding by a predetermined value or more. In the present specification, the user input  12  is called a ‘rapid user input  12 ’. Meanwhile, in the present invention, the user inputs  10  and  12  are not limited to the sliding touch input and may be implemented in various forms as described above. 
     First,  FIGS. 3 to 5  illustrate an exemplary embodiment of a case in which content  50  of the present invention includes a plurality of photographs. Referring to  FIG. 3 , the digital device  100  may receive the user input  10  to change the target area while displaying a photograph of a first target area  52  on the display unit  120 . The digital device  100  changes the target area to a second target area  52 ′ from the first target area  52  according to the user input  10 . In  FIG. 3 , the digital device  100  may change the target area to the second target area  52 ′ positioned at a right side of the first target area  52  in terms of a sequence according to the user input  10  which slides to a left side. The digital device  100  displays a photograph of the changed second target area  52 ′ on the display unit  12 . 
       FIG. 4  illustrates an exemplary embodiment in which the digital device  100  of  FIG. 3  receives the rapid user input  12 . Referring to  FIG. 4 , the digital device  100  may receive the rapid user input  12  to change the target area while displaying the photograph of the first target area  52  on the display unit  120 . The digital device  100  changes the target area to a second target area  52 ″ from the first target area  52  according to the rapid user input  12 . In the exemplary embodiment of the present invention, the second target area  52 ″ is an area which is increased compared to the first target area  52 . In  FIG. 4 , the first target area  52  is an area including one photograph of the content  50 , but the second target area  52 ″ changed by the rapid user input  12  is an area including more areas, that is, four photographs of the content  50 . 
     Meanwhile, according to the exemplary embodiment of  FIG. 4 , the digital device  100  may reduce a display scale of the second target area  52 ″ according to the increase of the second target area  52 ″. In the exemplary embodiment of  FIG. 4 , the digital device  100  divides a screen into four windows in order to show four photographs included in the second target area  52 ″ in the display unit  120  together. The four photographs included in the second target area  52 ″ are displayed on the respective divided windows. In this case, the digital device  100  may display the four photographs included in the second target area  52 ″ simultaneously by reducing the display scale of the photograph displayed on each window. 
       FIG. 5  illustrates another exemplary embodiment in which the digital device  100  of  FIG. 3  receives the rapid user input  12 . In the exemplary embodiment of  FIG. 5 , a part which is the same as or corresponds to the exemplary embodiment of  FIG. 4  will not be described in detail. Referring to  FIG. 5 , the digital device  100  receives the rapid user input  12  to increase the target area to the second target area  52 ″, however, may maintain a display scale of a corresponding target area to be the same as the display scale of the first target area  52 . To this end, the digital device  100  pans or tilts the plurality of windows of displaying the second target area  52 ″ to provide the panned or tilted windows. The digital device  100  allows the plurality of panned or tilted windows to overlap with each other to maintain the display scale of the second target area  52 ″ displayed on each window to be the same as the display scale of the first target area  52  without reducing the display scale of the second target area  52 ″. 
     In the exemplary embodiment of  FIGS. 4 and 5 , the digital device  100  may display the first target area  52  in the first window mode and the second target area  52 ″ in the second window mode. As illustrated, the second window mode provides more windows than the first window mode to display the first target area  52  onto the display unit  120 . Meanwhile, when the digital device  100  receives a subsequent user input to change the target area in the second window mode, the digital device  100  may display the changed target area while maintaining the second window mode. According to another exemplary embodiment of the present invention, the digital device  100  may measure the user input to change the target area in real time and perform conversion between the first window mode and the second window mode to correspond thereto. That is, when a speed of the user input to change the target area in the second window mode is lower than a predetermined speed, the digital device  100  is restored to the first window mode to display the changed target area. 
     According to yet another exemplary embodiment of the present invention, when contents that remain in a change direction of the target area are equal to or less than a predetermined amount in the second window mode, the digital device  100  may display the target area changed according to the continued user inputs  10  and  12  in the first window mode. In this case, the predetermined amount may represent absolute numerical values, for example, a predetermined number of displays pages, an area having a predetermined size, and the like. Further, the predetermined amount may represent a relative numerical value, for example, a relative ratio to all contents. That is, even though the digital device  100  receives the rapid user input  12 , when a sufficient amount of contents do not remain in a direction indicated by the corresponding input  12 , the digital device  100  may display a new target area in the first window mode. Accordingly, when the target area of the content is changed according to the rapid user input  12 , the digital device  100  according to the exemplary embodiment of the present invention may represent that the target area is close to a boundary of the content in the corresponding change direction. 
     Next,  FIGS. 6 and 7  illustrate an exemplary embodiment of a case in which the content  50  of the present invention includes a map content. Referring to  FIG. 6 , the digital device  100  may receive the user input  10  to change the target area while displaying the first target area  54  which is at least a part of the map content on the display unit  120 . The digital device  100  changes the target area to a second target area  54 ′ from the first target area  54  according to the user input  10 . In  FIG. 6 , the digital device  100  may change the target area to the second target area  54 ′ positioned at a right side of the first target area  54  on the map content according to the user input  10  which slides to a left side. The digital device  100  displays the changed second target area  54 ′ on the display unit  12 . 
       FIG. 7  illustrates an exemplary embodiment in which the digital device  100  of  FIG. 6  receives the rapid user input  12 . Referring to  FIG. 7 , the digital device  100  may receive the rapid user input  12  to change the target area while displaying the first target area  54  of the map content on the display unit  120 . The digital device  100  changes the target area to a second target area  54 ″ from the first target area  54  according to the rapid user input  12 . In the exemplary embodiment of the present invention, the second target area  54 ″ is an area which is increased compared to the first target area  54 . In  FIG. 7 , the second target area  54 ″ changed by the rapid user input  12  is an area including a larger range of the map content than the first target area  54  before the change. Meanwhile, as described in  FIG. 4 , the digital device  100  may reduce a display scale of the second target area  54 ″ according to the increase of the second target area  54 ″. The digital device  100  may display scale information of the corresponding target areas  54  and  54 ″, and the like as additional information while displaying each target area  54  or  54 ″. 
     As such, the digital device  100  according to the exemplary embodiment of the present invention may adjust the size of the displayed area to adaptively correspond to the speeds of the user inputs  10  and  12  to change an area of the content  50  to be displayed. The user may rapidly perform scrolling or page turning when the user intends to scan the content  50  rapidly. In this case, the digital device  100  of the present invention allows the user to scan the content  50  rapidly by increasing the size of the target area displayed on the display unit  120  at once. 
       FIGS. 8 and 9  illustrate another exemplary embodiment of the present invention. In the exemplary embodiment of  FIGS. 8 and 9 , a detailed description of a part which is the same as or corresponds to the exemplary embodiment of  FIGS. 3 to 7  will be omitted. First, referring to  FIG. 8 , the digital device  100  may receive the rapid user input  12  to change the target area while displaying a first target area  56 . The digital device  100  changes the target area to a second target area  56 ″ from the first target area  56  according to the rapid user input  12 . In this case, according to the exemplary embodiment of  FIG. 8 , the digital device  100  may display a downscaled content of the second target area  56 ″. In the present invention, the downscaled content represents a content having information of an amount which is smaller than information in which a corresponding target area is displayed on the display unit  120  in a basic state. For example, the downscaled content includes various types of contents including a thumbnail, an icon, a base layer picture of scalable video coding, and the like, and besides, includes various means having information of an amount which is smaller than that of actual content of the target area and representing content of the corresponding target area. 
     According to the exemplary embodiment of the present invention, the digital device  100  may display the second target area  56 ″ in the second window mode. The second window mode provides more windows than the first window mode to display the first target area  56  onto the display unit  120 . According to the exemplary embodiment of the present invention, the digital device  100  may display downscaled content of the second target area  56 ″ in each of the plurality of windows the second window mode. Further, the digital device  100  pans or tilts the plurality of windows of the second window mode to provide the panned or tilted windows as described above. 
     Meanwhile, the digital device  100  may receive all contents  50  or the target area from the server or the cloud through the network in order to display the target area of the content  50  in the display unit  120 . According to the exemplary embodiment of the present invention, the digital device  100  may receive the downscaled content through a communication unit (not illustrated) when displaying the downscaled content of the second target area  56 ″. An original content of the downscaled content may be received when there is a request from the user for the corresponding target area. As such, the digital device  100  according to the exemplary embodiment of the present invention may efficiently manage a data transmission amount when receiving and displaying the content  50  through the network in real time. 
     According to the exemplary embodiment of the present invention, the digital device  100  may receive content positioned in a subsequent sequence of a target area to be changed according to the user inputs  10  and  12  in advance. The content that is received in advance is content of a subsequent sequence positioned in a content change direction based on the target area to be changed. Therefore, the digital device  100  may change the target area at a high response speed and display the target area according to the continued user inputs  10  and  12 . Meanwhile, according to another exemplary embodiment of the present invention, the digital device  100  may adaptively control the amount of the content which is received in advance according to the speeds of the user inputs  10  and  12 . That is, when the rapid user input  12  is received, the digital device  100  may receive more contents than a case in which the general user input  10  is received in advance. For example, if the digital device  100  receives three display pages in a direction corresponding to the user input  10  in advance in the first window mode, the digital device  100  may receive ten display pages in a direction corresponding to the rapid user input  12  in advance in the second window mode. 
     Next, referring to  FIG. 9 , the digital device  100  may provide a virtual track  30  and an indicator  32  in the second window mode.
