     DESCRIPTION OF EMBODIMENTS 
     Preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Throughout the specification and the drawings, the same reference numerals are given to constituent elements having substantially the same functional configuration and the description thereof will not be repeated. 
     In the specification and the drawings, different reference numerals are sometimes given to the end of the same reference numeral via a hyphen to distinguish a plurality of constituent elements having substantially the same functional configuration from each other. For example, a plurality of constituent elements having substantially the same functional configuration are distinguished as gap regions  11 - 1  and  11 - 2 , as necessary. In the embodiments described below, different states of the same functional configuration are distinguished from each other by giving different reference numerals via a hyphen after the same reference numeral. However, when it is not necessary to distinguish the plurality of constituent elements having substantially the same functional configuration from each other, only the same reference numeral is given to the constituent elements. For example, when it is not necessary to distinguish the gap regions  11 - 1  and  11 - 2  from each other, the gap regions  11 - 1  and  11 - 2  are simply referred to as the gap regions  11 .

     (1-1. Functional Configuration) 
     First, the functional configuration of an information processing apparatus according to a first embodiment of the present disclosure will be described with reference to  FIG. 1 .  FIG. 1  is a block diagram illustrating the functional configuration of the information processing apparatus according to the first embodiment of the disclosure. 
     An information processing apparatus  100   a  illustrated in  FIG. 1  is an apparatus that operates based on a user&#39;s operation. Examples of the information processing apparatus  100   a  include a portable telephone, a personal computer (PC), a video processing apparatus, a game console, a home appliance, and a music reproducing apparatus. 
     The information processing apparatus  100   a  includes a display unit  101 , a detecting unit  103 , an operation recognizing unit  105 , and a display control unit  107  as main units. 
     (Display Unit  101 ) 
     The display unit  101  has a function of providing a display screen to a user. The display unit  101  may be a display device such as a liquid crystal display (LCD) device or an organic light emitting diode (OLED) display device. 
     (Detecting Unit  103 ) 
     The detecting unit  103  has a function of detecting a position input by a pointing device on a display screen. Examples of the pointing device include a touch sensor, a mouse, a button, a trackball, and other controllers. In this embodiment, it is assumed that the detecting unit  103  is a touch sensor superimposed on the display unit  101  and detects the position of a finger F which is the operation body on the display screen. The touch sensor used here may be, for example, a contact type touch sensor that detects the position of the finger F touching on the display screen. Alternatively, the touch sensor used here may be a non-contact type touch sensor that detects the position of the finger F on the display screen in a non-contact manner. Alternatively, the touch sensor used here may detect a pushing operation of a user on the display screen. 
     (Operation Recognizing Unit  105 ) 
     The operation recognizing unit  105  has a function of recognizing a process indicated by an operation pattern input by the user. The operation pattern is determined based on the position of the operation body. Specifically, the operation pattern is determined based on various conditions such as a detection timing of the position of the operation body and a change pattern of the position of the operation body. The operation recognizing unit  105  determines the operation pattern to recognize a process associated with the operation pattern in advance. The operation recognizing unit  105  can recognize an operation, such as a scrolling operation, an expanding operation, a reducing operation, or a rotating operation, of changing the display state of a display target. 
     (Display Control Unit  107 ) 
     The display control unit  107  has a function of controlling display of a display screen on the display unit  101 . The display control unit  107  can generate the display screen based on the process recognized by the operation recognizing unit  105  and display the display screen on the display unit  101 . For example, the display control unit  107  can function as a region display unit that displays a display target on a predetermined display region. The display control unit  107  can function as a display state control unit that controls the display state of a display target. Here, the display target is a list of a plurality of items. However, the display target is not limited to the list. For example, the display target may be a map, an image, a web page, or the like. The display control unit  107  can display a part or the entirety of a display target on a display region. The display state of the display target is changed based on an operation recognized by the operation recognizing unit  105 . 
     The display control unit  107  can display the display state of a display target in response to detection of a first operation satisfying a predetermined first condition or detection of a second operation satisfying a predetermined second condition. The display control unit  107  can restrain a specific display target from being displayed on the display unit in response to reception of the first operation based on boundary information associated with the specific display target which is the display target specified. The display control unit  107  can display the specific display target on the display unit  101 , when the second operation is received in the state where the specific display target is restrained from being displayed. When the display target is a list and the beginning of the list is displayed, the specific display target is the termination of the list. When the termination of the list is displayed, the specific display target is the beginning of the list. 
     When the first operation satisfying the predetermined first condition is detected, the display control unit  107  can change the display state of the display target. Specifically, for example, the display target is a list and the first operation may be a normal scrolling operation. At this time, when the scrolling operation is detected, the display control unit  107  can scroll and change a portion displayed in the display region of the list. When the second operation satisfying the predetermined second condition is detected at a boundary set in advance as the display target, the display control unit  107  can change the display state of the display target. For example, specifically, when a scrolling operation of which an operation amount exceeds a predetermined threshold value is detected at one end (the beginning or the termination) of the list, the display control unit  107  can scroll and display the list by turning around the one end of the list to the other end of the list. At this time, the second condition is stricter than the first condition. The first and second conditions may be set based on at least one of a distance corresponding to the amount of the scrolling operation, a ratio of the length of a display region, and a time. For example, it is assumed here that the first condition is a condition in which the amount of the scrolling operation exceeds a predetermined first threshold value and the second condition is a condition in which the amount of the scrolling operation exceeds a second threshold value greater than the first threshold value. However, the present technology is not limited to this example. For example, the second condition may be set such that a new operation is performed in addition to the first condition. For example, the second condition may be set such that a state where the amount of the scrolling operation exceeds the first threshold value continues for a predetermined time. 
     On the assumption that one side of the boundary of the display target is referred to as a first side and the other side of the boundary of the display target is referred to as a second side, the display control unit  107  can display the first and second sides in different expression ways. When the first and second sides are displayed in different ways, a user recognizes that a boundary is present. When the display target is displayed beyond the boundary through the second operation, the display control unit  107  may reverse the expressions of the first and second sides. Thus, in such a configuration, the user can recognize that the display target is beyond the boundary. The display control unit  107  can display the display target on the first side in an expression corresponding to the operation amount of the first operation. At this time, the first side may be the other side (the other end of the list displayed when the second operation is performed) of the boundary. Here, the display control unit  107  may display the first side of the display target outside the display region. 
     When the first operation is detected at the boundary of the display target, the display control unit  107  can perform a display suggesting that the display target can be displayed beyond the boundary. For example, at this time, the display control unit  107  may display a mark (for example, an arrow) indicating that the list is turned around beyond the boundary and displayed. At this time, the display control unit  107  can display the mark in an expression way corresponding to the operation amount of the first operation. Specifically, the display control unit  107  may display the mark with a length corresponding to the operation amount of the first operation. 
     When the operation recognizing unit  105  recognizes an operation based on the position designated by an operation body on the display screen and the display target is detected through the second operation and is displayed beyond the boundary, the display control unit  107  can change the display state of the display target such that the position of the operation body is superimposed on the position of the boundary. Specifically, when the other end of the list is turned around and displayed beyond the boundary, the display control unit  107  may scroll and display the list so that the end of the list reaches the position of the operation body. 
     Examples of the function of the information processing apparatus  100   a  according to this embodiment have hitherto been described. The above-described respective constituent elements may be configured using general units or circuits or may be configured by hardware specialized for the functions of the respective constituent elements. Further, the functions of the respective constituent elements may be performed by reading a control program, which describes a processing order in which the functions are realized by an arithmetic device such as a central processing unit (CPU), from a storage medium such as a read-only memory (ROM) or a random access memory (RAM), which stores the control program, analyzing the control program, and executing the control program. Accordingly, a configuration to be appropriately used may be modified in accordance with a technical level at which this embodiment is realized. 
     A computer program configured to realize the functions of the information processing apparatus  100   a  according to the above-described embodiment may be created and mounted on a personal computer or the like. Further, a computer readable recording medium that stores the computer program may be provided. Examples of the recording medium include a magnetic disk, an optical disc, a magneto-optical disc, and a flash memory. Furthermore, the computer program may be delivered via a network or the like without use of a recording medium. 
     (1-2. Overview of List Display) 
     Next, the overview of list display according to this embodiment will be described with reference to  FIGS. 2 and 3 .  FIG. 2  is a diagram illustrating an example of display transition of a list displayed in the information processing apparatus according to this embodiment.  FIG. 3  is a diagram illustrating another example of the display transition of the list displayed by the information processing apparatus according to this embodiment. 
     First, the description will be made with reference to  FIG. 2 . The display control unit  107  of the information processing apparatus  100   a  can display a list of items including an item “AAAAAAAA” to an item “ZZZZZZZZ” For example, here, the item “AAAAAAAA” is referred to as a beginning of the list and the item “ZZZZZZZZ” is referred to as a termination of the list. However, the present invention also includes embodiments where scrolling is performed between different lists or images. For example,  FIG. 2 , state  3  would include the end of a first list and the start of a second list, rather than the end and the start of the same list as shown. 
     Referring to state  1 , the display control unit  107  displays the item “AAAAAAAA” of the list to an item “FFFFFFFF” of the list in the display region. When the user performs a scrolling operation on the list with the finger F, the display control unit  107  can scroll and display the list in response to the scrolling operation. When the user continues the scrolling operation, the display control unit  107  can scroll and display the list to the termination of the list. The scroll display may be scrolled in an inertial manner in response to the scrolling operation of the user. That is, the display control unit  107  can control the display such that the list is scrolled in the inertial manner even when the user performs no operation with his/her finger. When the list is scrolled up to the termination of the list, the display control unit  107  can stop the scroll in the termination. That is, in the end portion of the list, the list is not scrolled in the inertial manner (state  2 ). 
     When the user further performs the scrolling operation in the end portion of the list, the display control unit  107  can turn around the beginning of the list and display the list. However, until the scrolling operation satisfies the second condition, the display control unit  107  performs a display suggesting that the display control unit  107  can turn around and display the list as in state  3 . In state  3 , when the user detaches the finger F before the second condition is satisfied, the display control unit  107  may return the display state to a state (state  4 ) where the termination of the list is displayed. On the other hand, when the second condition is satisfied by further performing the scrolling operation in state  3 , the display control unit  107  can scroll and display the list beyond the boundary between the termination and the beginning of the list (state  5 ). For example, the display control unit  107  can scroll and display the list so that the beginning of the list reaches the end of the display region (state  6 ). 
       FIG. 3  illustrates another example of the display transition of the list. For example, when the user further performs the scrolling operation in a state where the display suggests that the list can be turned around and displayed, as in state  3 , and thus the second condition is satisfied, the list is turned around beyond the boundary and is displayed (state  3 - 1 ). Then, the display control unit  107  may automatically scroll the list until the boundary is superimposed on the position of the finger F (state  7 ). State  7  is a state where an operation of scrolling the list beyond the boundary is not confirmed. For example, when the user performs a flicking operation upward or detaches the finger F from the screen, the state is returned to state  4  where the termination of the list is displayed. On the other hand, when the user performs a flicking operation downward in state  7 , the display control unit may scroll and display the list so that the beginning of the list reaches the end of the display region (state  6 ). 
     (1-3. Example of Effect Showing End Point) 
     Next, an example of an effect not showing the preceding portion beyond the boundary from an end point will be described with reference to  FIGS. 4 to 6 .  FIG. 4  is a diagram illustrating an example of an effect showing an end point of the list displayed by the information processing apparatus according to this embodiment.  FIG. 5  is a diagram illustrating another example of the effect showing an end point of the list displayed by the information processing apparatus according to this embodiment.  FIG. 6  is a diagram illustrating further another example of the effect showing an end point of the list displayed by the information processing apparatus according to this embodiment. 
     For example, when the user performs a scrolling operation from the initial state where a boundary B is displayed at the end of the display region, as illustrated in  FIG. 4 , the display control unit  107  can display a new gap region  11  in accordance with the amount of the scrolling operation when the scrolling operation is performed. The gap region is displayed such that a gap between the boundary B and the beginning (here, the item “AAAAAAAA”) of the list is opened. The display control unit  107  can close the gap region  11  and return the display state of the list to the original state of the list, when the user stops the scrolling operation. 
     As illustrated in  FIG. 5 , when the user stops the scrolling operation, the display control unit  107  may not completely close the gap region  11 . For example, the display control unit  107  may control the display of the gap region  11  such that the vertical width of a gap region  11 - 2  is narrower than that of the gap region  11 - 1  when the scrolling operation is performed. 
     The effect showing the end point is not limited to the display of the gap region  11 . For example, as illustrated in  FIG. 6 , the display control unit  107  may display the list such that the vertical width of a part of an item of the list is broadened when the scrolling operation is performed. The display control unit  107  can return the vertical width of the item to the original state when the user stops the scrolling operation. 
     The user can recognize the end point of the list by the above-described effect. For example, when the scroll is simply stopped at the end point without use of the effect showing the end point, it is difficult for the user to explicitly recognize whether the reason why the scroll operation is not performed is because the scroll operation stops at the end point or because the information processing apparatus  100   a  has not recognized the operation. Accordingly, in such a configuration, the user can discriminate and recognize between the case in which the information processing apparatus  100   a  may not recognize the operation and the case in which the end point appears and thus the scrolling operation may not be further performed. 
     (1-4. Example of Effect Suggesting that List is Displayed Beyond Boundary) 
     Next, an example of an effect suggesting that the list can be displayed beyond the boundary from the end point will be described with reference to  FIGS. 7 and 8 .  FIG. 7  is a diagram illustrating an example of the effect suggesting that the list can be turned around and displayed beyond the end point of the list displayed by the information processing apparatus according to this embodiment.  FIG. 8  is a diagram illustrating another example of the effect suggesting that the list is turned around and displayed beyond the end point of the list displayed by the information processing apparatus according to this embodiment. 
     For example, when the user performs the scrolling operation from the initial state where the boundary B is displayed at the end of the display region, as illustrated in  FIG. 7 , the display control unit  107  may display a mark M suggesting that the list can be turned around beyond the boundary and displayed when the scrolling operation is performed. The display control unit  107  can stop displaying the mark M when the user stops the scrolling operation. For example, the mark M can be displayed outside the display region of the list. Further, the display control unit  107  may display the mark M so as to have a size corresponding to the amount of the scrolling operation. For example, the display control unit  107  may display the mark M such that a size is larger as the amount of the scrolling operation is larger. 
     When the user performs the scrolling operation from the initial state where the boundary B is displayed at the end of the display region, as illustrated in  FIG. 8 , the display control unit  107  can display the first side which is a part of the other end (here, the termination) of the list outside the display region in a different way from the second side at the time of the scrolling operation. The display control unit  107  can stop displaying the first side, when the user stops the scrolling operation. The first side may be expressed with a character paler than the second side. 
     The user can recognize the end portion of the list and can also recognize that the list can be turned around and displayed beyond the end portion of the list by using the above-described effect. 
     (1-5. Example of Effect after List is Displayed Beyond Boundary) 
     Next, an example of an effect after the list is displayed beyond the boundary will be described with reference to  FIGS. 9 and 10 .  FIG. 9  is a diagram illustrating an example of the effect after the list is displayed beyond the boundary of the list displayed by the information processing apparatus according to this embodiment.  FIG. 10  is a diagram illustrating another example of the effect after the list is displayed beyond the boundary of the list displayed by the information processing apparatus according to this embodiment. 
     For example, as illustrated in  FIG. 9 , the display control unit  107  may change the expression ways of the first and second sides before and after the list is displayed beyond the boundary. At this time, the display control unit  107  can reverse the expression ways of the first and second sides. 
     As illustrated in  FIG. 10 , the display control unit  107  can automatically scroll and display the list so that the boundary B reaches the position of the finger F after the list is displayed beyond the boundary. Thereafter, the display control unit  107  can control the display of the list in accordance with the direction of a flicking operation performed by the user, as described above with reference to  FIG. 3 . Alternatively, the display control unit  107  may control the display of the list so that the list is returned to the state before the list is displayed beyond the boundary, when the user detaches the finger from the state. 
     (1-6. Example of Operation) 
     Next, an example of an operation of the information processing apparatus according to this embodiment will be described with reference to  FIG. 11 .  FIG. 11  is a flowchart illustrating an example of an operation of the information processing apparatus according to this embodiment. 
     First, when the operation recognizing unit  105  detects that the user performs a scrolling operation based on the position of an operation body detected by the detecting unit  103  (S 100 ), the display control unit  107  scrolls and displays the list in response to the scrolling operation (S 105 ). The display control unit  107  can display the list scrolled by the scroll amount in response to the scrolling operation. The scrolling operation may be a so-called flicking operation. When the flicking operation is detected, the display control unit  107  can scroll the list in an inertial manner. 
     Next, the display control unit  107  determines whether the list displayed in the display region reaches an end portion (S 110 ). When the display control unit  107  determines that the list reaches the end portion, the display control unit  107  determines whether the scrolling operation is detected by the operation recognizing unit  105  (S 115 ). Here, when the scrolling operation is detected, the display control unit  107  performs a display indicating that a turning display is possible (S 120 ). For example, the display may be the mark M such as an arrow or may be a part of the turned list. 
     When the operation recognizing unit  105  recognizes that the scroll amount detected by the detecting unit  103  is equal to or greater than a predetermined threshold value (second threshold value) (Yes at S 125 ), the display control unit  107  scrolls and displays the turned list to the other end portion of the list (S 130 ). p &lt;2. Second Embodiment&gt; 
     Next, the functional configuration of an information processing apparatus according to a second embodiment of the present disclosure will be described with reference to  FIG. 12 .  FIG. 12  is a block diagram illustrating the functional configuration of the information processing apparatus according to the second embodiment of the present disclosure. 
     An information processing apparatus  100   b  according to the second embodiment of the present disclosure includes a detection information acquiring unit  104 , an operation recognizing unit  105 , and a display control unit  107  as the main units.
