## Background
CROSS-REFERENCE TO PRIOR APPLICATION
This application is a continuation of U.S. patent application Ser. No. 15/403,665 (filed on Jan. 11, 2017), which is a continuation of U.S. patent application Ser. No. 13/242,129 (filed on Sep. 23, 2011 and issued as U.S. Pat. No. 9,619,135 on Apr. 11, 2017), which claims priority to Japanese Patent Application No. 2010-228303 (filed on Oct. 8, 2010), which are all hereby incorporated by reference in their entirety.


BACKGROUND
The present disclosure relates to an information processing apparatus, an information processing method, and a program.
In recent years, a touch panel which can detect contact with an operating object has been in widespread use. Since such a touch panel can detect a position at which the operating object comes into contact, a user can perceive the position at which the operating object comes into contact (for example, refer to JP 2010-157189A).
Further, a touch panel which can detect proximity of the operating object thereto has also been in widespread use. Since such a touch panel can detect a position to which the operating object comes close, the user can grasp the position to which the operating object comes close.
SUMMARY
However, in the case where the above-mentioned general touch panel was used, there was an issue that it was difficult to grasp, in a stage in which an operation of moving a display object is performed, how far the display object can be moved.
In light of the foregoing, it is desirable to provide a novel and improved technology which is capable of allowing the user to grasp, in the stage in which the operation of moving the display object is performed, how far the display object can be moved.
Accordingly, there is provided a method for modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion. The method further comprises detecting movement, in a member direction, of an operating member with respect to the edge. The method still further comprises moving, if the edge is not in the location, the object in an object direction corresponding to the detected movement; and modifying, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.
In a second aspect, there is provided a non-transitory computer-readable medium storing instructions which, when executed by a computer, perform a method of modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion. The method further comprises detecting movement, in a member direction, of an operating member with respect to the edge. The method still further comprises moving, if the edge in not in the location, the object in an object direction corresponding to the detected movement; and modifying, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.
In a third aspect, there is provided an apparatus for modifying an image, comprising a memory and a processor executing instructions stored in the memory. The processor executes instructions stared in the memory to display an image, the image comprising a portion of an object; and determine if an edge of the object is in a location within the portion. The processor further executes instructions stored in the memory to detect movement, in a member direction, of an operating member with respect to the edge. The processor still further executes instructions stored in the memory to move, if the edge is not in the location, the object in an object direction corresponding to the detected movement; and modify, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.

1. EMBODIMENT
[1-1. Outline of Information Processing Apparatus]
FIG. 1 is a diagram illustrating an outline of an information processing apparatus according to an embodiment of the present disclosure. As shown in FIG. 1, an information processing apparatus 100A according to the embodiment of the present disclosure includes a display region 141. On the display region 141, a part of a display object DB1 is displayed by the information processing apparatus 100A. Further, an information processing apparatus 100B according to the embodiment of the present disclosure displays a peat (i.e., a portion) of a display object DB2 on the display region 141.
Here, the display objects such as the display object DB1 and the display object DB2 each have an edge DT, and let us assume that that the edge DT represents the upper edge of each display object. In this case, when a user scrolls the display object in the downward direction, the edge DT eventually reaches the upper edge (i.e., a location) of the display region 141. After the edge DT reached the upper edge of the display region 141, the display object cannot be scrolled in the downward direction any farther.
The embodiment of the present disclosure enables the user to grasp, in the stage in which the operation of moving the display object is performed, how far the display object can be moved. In order to realize such a function, in the case of scrolling the display object in the downward direction for example, the information processing apparatus 100 according to the embodiment of the present disclosure reads a display area at a position proceeded a read-ahead distance PR in the upward direction from the upper edge of the display region 141. For example, in the case of the display object DB1 displayed by the information processing apparatus 100A on the display region 141, in which the position obtained by proceeding the read-ahead distance PR in the upward direction from the upper edge of the display region 141 is below the edge DT (upper edge) of the display object DB1, the information processing apparatus 100A may not notify the user that the edge DT nearly reaches the display region 141, because there is still some time for the edge DT (upper edge) to reach the upper edge of the display region 141.
On the other hand, for example, in the case of the display object DB2 displayed by the information processing apparatus 100B on the display region 141, in which the position obtained by proceeding the read-ahead distance PR in the upward direction from the upper edge of the display region 141 is above the edge DT (upper edge) of the display object DB2, the information processing apparatus 100B notifies the user that the edge DT nearly reaches the display region 141, because the edge DT (upper edge) reaches the upper edge of the display region 141 after a short time.
Note that, for an operation for causing the display object to be scrolled, there are assumed a flick operation, a drag operation, ad the like to a position detection device such as a touch panel, but it is not particularly limited as to what kind of operation is performed to what hardware. It is necessary that the operation for scrolling the display object be at least an operation that a device can recognize the direction in which the display object is to be moved. Further, in the embodiment of the present disclosure, the operation of moving the display object is performed by the flick operation or the drag operation using an operating object OP (i.e., an operating to member). Further, it goes without saying that the direction in which the display object is scrolled is not limited to the downward direction and may be the upward direction, the left direction, or the right direction.
[1-2. Case where Edge of Display Object does not Reach Display Region at End of Flick]
FIG. 2 is a diagram illustrating an operation of the information processing apparatus 100 according to the embodiment of the present disclosure in a case where the edge of the display object does not reach the display region at the end of the flick. As shown in FIG. 2, a information processing apparatus 100C causes a part of the display object DB1 to be displayed on the display region 141. When the flick operation in the downward direction is performed by the operating object OP in this state, it is assumed that the following corresponds to a region DR1 that is displayed on the display region 141 at the end of the flick operation in theory: a region within the display object DB1 obtained by proceeding the distance corresponding to the intensity (i.e., velocity) of the flick operation from the region displayed on the display region 141 in the upward direction of the display object DB1.
As shown in FIG. 2, at the end of the flick, an information processing apparatus 100D causes the region DR1 that is displayed on the display region 141 to be displayed at the end of the flick in theory. In such a case, since the edge DT (upper edge) of the display object DB1 does not reach the upper edge of the display region 141, the movement of the display object DB1 by the flick operation is performed at a first acceleration, in a usual manner.
[(1-3. Case where Edge of Display Object Reaches Display Region at End of Flick]
FIG. 3 is a diagram illustrating an operation of the information processing apparatus 100 according to the embodiment of the present disclosure in a case where the edge of the display object reaches the display region at the end of the flick. As shown in FIG. 3, an information processing apparatus 100E causes a part of the display object DB1 to be displayed on the display region 141. When the flick operation in the downward direction is performed by the operating object OP in this state, it is assumed that the following corresponds to a region DR2 that is displayed on the display region 141 at the end of the flick in theory: a region within the display object DB1 obtained by proceeding the distance corresponding to the intensity of the flick operation from the region displayed on the display region 141 in the upward direction of the display object DB1.
As shown in FIG. 3, at the end of the flick, although an information processing apparatus 100F attempts to cause region DR2 to be displayed on the display region 141, which is to be displayed on the display region 141 at the and of the flick in theory, the information processing apparatus 100F cannot cause the region DR2 to be displayed, because the edge DT (upper edge) of the display object DB1 reaches the edge (upper edge) of the display region 141. In such a case, the movement of the display object DB1 is performed by reducing the movement velocity, for example, by rapidly slowing down the movement of the display object DB1 at a second acceleration.
[1-4. Functional Configuration of Information Processing Apparatus]
FIG. 4 is a diagram showing a functional configuration of the information processing apparatus according to the embodiment of the present disclosure. The information processing apparatus 100 according to the embodiment of the present disclosure includes at least a detection section 110, a determination section 120, and a display control section 130.
The detection section 110 includes a position detection device 210, and has a function of detecting a movement operation to the display object performed by the operating object OP. As described above, for example, the detection section 110 can detect the flick operation and the drag operation performed by the operating object OP as the movement operation to the display object performed by the operating object OP. However, the movement operation performed by the operating to object OP is not limited thereto, and the movement operation may be an input to an input device such as arrow key or a joystick.
The determination section 120 has a function of determining, in the case where the display object is moved a predetermined distance in a movement direction (i.e., an object direction) based on the movement operation detected by the detection section 110, whether the edge DT of the display object reaches the display region 141. In the case where the movement operation detected by the detection section 110 has a component in a predetermined direction (i.e., a member direction) the determination section 120 adopts the predetermined direction as the movement direction. For example, in the case where the movement operation is performed in an obliquely downward direction, the determination section 120 recognizes the movement direction based on the movement operation as the downward direction, and determines the case of moving the display object a predetermined distance in the downward direction.
The predetermined distance representing the distance which the display object is moved can be decided in advance, for example. In the example described above, for example, in the example shown in FIG. 2, it is determined by the determination section 120 that, in the case where the display object DB1 is caused to so be moved a predetermined distance in the movement direction (downward direction) based on the movement operation, the edge DT of the display object does not reach the display region 141. Further, for example, in the example shown in FIG. 3, it is determined by the determination section 120 that, in the case where the display object DR1 is caused to be moved a predetermined distance in the movement direction (for example, downward direction) based on the movement operation, the edge DT of the display object reaches the display region 141.
As shown in FIG. 2, the display control section 130 has a function of performing control such that the display object is moved in the movement direction (for example, downward direction). At the same time, when it is determined by the determination section 120 that, in the case where the display object is caused to be moved a predetermined distance in the movement direction, the edge DT (for example, upper edge) of the display object reaches the display region 141, the display control section 130 has a function of performing control such that a predetermined first display is shown on the display region 141. As for the predetermined first display, there are assumed various displays, which will be described in detail below.
The information processing apparatus 100 may further include a storage section 150. The storage section 150 is configured from, for example, a storage device such as a non-volatile memory. The storage section 150 has a function of storing a program for realizing the determination section 120, the display control section 130, a processing section 160, or the like, and a function of storing various types of data used when the program is executed, and the like. Further, the storage section 150 can store various thresholds and the like.
The information processing apparatus 100 may further include a display section 140. The display section 140 is configured from, for example, a display device. The display section 140 includes the display region 141, and has a function of displaying the display object on the display region 141 based on the control of the display control section 130. In the example described with reference to FIG. 2, the display section 140 is capable of displaying a part of the display object or the like on the display region 141 based on the control of the display control section 130.
The storage section 150 mores information about the edge DT of the display object, for example. The information about the edge DT of the display object represents information about distance from the edge DT of the display object to each display position on the display object, for example. The determination section 120 can determine whether the edge DT of the display object reaches the display region 141, based on the information about the edge DT of the display object, a position of a display area currently being displayed on the display object, the movement direction, and the predetermined distance, for example.
Further, the storage section 150 may store the display object. In that case, the determination section 120 can acquire a display area of a position obtained by going back the predetermined distance in a direction opposite to the movement direction on the basis of a position of a display area currently being displayed on the display object, from the display object stored in the storage section 150. The determination section 120 can determine whether the edge DT of the display object reaches the display region 141 based on the acquired display area. In the display area, these is set information about a distance from the edge DT of the display object to the display area on the display object, because whether the edge DT of the display object reaches the display region 141 can be determined based on the information about the distance.
The information processing apparatus 100 may further include the processing section 160. The processing section 160 can execute processing corresponding to an item selected by the operating object OP, for example.
The information processing apparatus 100 may include a reception section 170. The reception section 170 has a function of receiving information about the edge DT of the display object, for example. In that case, the determination section 120 can determine whether the edge DT of the display object reaches the display region 141, based on the information about the edge DT of the display object, a position of a display area currently being displayed on the display object, the movement direction, and the predetermined distance. The information about the edge DT of the display object can be received from a predetermined server via a network, for example.
The reception section 170 may receive a display area of a position obtained by going back the predetermined distance in a direction opposite to the movement direction on the basis of a position of a display area currently being displayed on the display object. In that case, the determination section 120 can determine whether the edge DT of the display object reaches the display region 141 based on the display area received by the reception section 170. The display area can also be received from a predetermined server via a network, for example.
Further, as described with reference to FIG. 3, in the case where the edge of the display object reaches the display region at the end of a flick, the movement of the display object is performed by reducing the movement velocity, for example, by rapidly slowing down the movement of the display object. To be more specific, first, the determination section 120 further determines whether the movement operation detected by the detection section 110 is the flick operation. In the case of determining that the movement operation is the flick operation, the determination section 120 further determines whether the edge DT of the display object passes through the edge of the display region 141 corresponding to the edge DT of the display object by the movement of the display object caused by the flick operation.
In the case where the determination section 120 determines that the edge DT of the display object passes through the edge of the display region 141 corresponding to the edge DT of the display object by the movement of the display object caused by the flick operation, the display control section 130 sets a larger deceleration coefficient associated with the movement of the display object than in the case where it is determined that the edge DT of the display object does not pass through the edge of the display region 141 corresponding so the edge DT of the display object by the movement of the display object caused by the flick operation.
The determination section 120, the display control section 130, the 6 processing section 160, and the like are configured from, for example, a CPU (Central Processing Unit) and a RAM (Random Access Memory), and the functions thereof are realized by developing in the RAM a program stored in the storage section 150 and executing the developed program by the CPU. However, it is not limited to such a configuration, and the display control section 130 and the processing section 160 may be configured from a dedicated hardware.
[1-5. Hardware Configuration of Information Processing Apparatus]
FIG. 5 is a hardware configuration diagram of the information processing apparatus according to the embodiment of the present disclosure. As shown in FIG. 5, the information processing apparatus 100 according to the embodiment of the present disclosure includes the position detection device 210, a CPU 220, a RAM 230, a display device 240, and a non-volatile memory 250.
The position detection device 210 has a position detection plane, and has a function of detecting proximity coordinates or contact coordinates of the operating object OP to the position detection plane. As the position detection device 210, a capacitive touch panel can be used, for example. In addition, an optical touch panel can be used as the position detection device 210, for example. In addition, a USB (Universal Serial Bus) camera can be used as the position detection device 210, for example.
The CPU 220 functions as an arithmetic processing unit and a control unit and controls the overall operation inside the information processing apparatus 100 or a portion thereof according to various programs recorded in the non-volatile memory 250 or the RAM 230.
The RAM 230 stores a program used by the CPU 220, a parameter that appropriately changes during execution thereof, and the like.
The display device 240 is configured from a device capable of visually notifying the user of information, such as an LCD (Liquid Crystal Display) and an organic EL (Electroluminescence) display device. The display device 240 outputs results obtained by various processes performed by the information processing apparatus 100. To be specific, the display device 240 displays the results obtained by various processes performed by the information processing apparatus 100 on the display region 141 in text or image form. Further, the display device 240 may be provided to the information processing apparatus 100, or may be provided outside the information processing apparatus 100.
The non-volatile memory 250 is a device for storing data, and includes, for example, a magnetic storage device such as an HDD (Hard Disk Drive), a semiconductor storage device, an optical storage device, or a magneto-optical storage device. The non-volatile memory 250 stores programs executed by the CPU 220 and various kinds of data.
Heretofore, there has been shown an example of the hardware configuration capable of realizing the functions of the information processing apparatus 100 according to the embodiment of the present disclosure. Each of the structural elements described above may be configured using a general-purpose material, or may be configured from hardware dedicated to the function of each structural element. Accordingly, the hardware configuration to be used can be changed as appropriate according to the technical level at the time of carrying out the embodiment of the present disclosure.
[1-6. Operation in Case where Flick Operation is Performed]
FIG. 6 is a flowchart showing a flow of an operation performed by the information processing apparatus 100 according to the embodiment of the present disclosure in the case where the flick operation is performed. Note that, although the example shown in FIG. 6 represents an example in which the movement direction is the downward direction, the movement direction is not particularly limited, and may be the upward direction, the left direction, or the right direction, for example.
As shown in FIG. 6, the determination section 120 determines whether the operation detected by the detection section 110 is flicking (Step S101). In the case of determining that the operation detected by the detection section 110 is not flicking (“No” in Step S101), the determination section 120 returns to Step S101. In the case of determining that the operation detected by the detection section 110 is flicking (“Yes” in Step S101), the determination section 120 determines whether the operation performed in the immediately preceding processing flow detected by the detection section 110 was the flick operation (Step S102).
In the case of determining that the operation performed in the immediately preceding processing flow detected by the detection section 110 was also the flick operation (“Yes” in Step S102), the determination section 120 determines whether there is the edge DT (upper edge) of the display object within the read-ahead distance (Step S103). In the case of determining that there is no edge DT (upper edge) of the display object within the read-ahead distance (“No” in Step S103), the determination section 120 returns to Step S101. In the case where it is determined by the determination section 120 that there is edge DT (upper edge) of the display object within the read-ahead distance (“Yes” in Step S103), the display control section 130 calculates a predetermined parameter such as the above-mentioned deceleration coefficient associated with the movement of the display object (Step S104), starts a flick process up to the upper edge of the display object (Step S105), and returns to Step S101.
[1-7. Screen Displayed by Operation at Stage in which Edge of Display Object Reaches Display Region]
FIG. 7 is a diagram illustrating a screen example displayed by the information processing apparatus 100 according to the embodiment of the present disclosure in a case where it is determined that the edge DT of the display object reaches the display region 141. As described above, when it is determined by the determination section 120 of the information processing apparatus 100G that, in the case where a display object DB3 is caused to be moved a predetermined distance in the movement direction, the edge DT (for example, upper edge) of the display object reaches the display region 141, the display control section 130 of an information processing apparatus 100G performs control such that a predetermined first display G (i.e., an image) is shown on the display region 141.
Further, in the case where the movement operation performed by the operating object OP is detected by the detection section 110 when the edge DT of the display object has already reached the display region 141, the display control section 130 of an information processing apparatus 100H performs control such that a predetermined second display (i.e., a modified image) H1, H2, which is different from the predetermined first display G is shown on the display region 141. The state where the edge DT of the display object has already reached the display region 141 represents, for example, a state where the edge DT (upper edge) of the display object has already reached the edge (upper edge) of the display region 141 so corresponding to the edge DT (upper edge) of the display object. Further, the movement operation being referred to here represents a movement operation in a direction corresponding to that in which the edge DT of the display object enters inside the display region 141.
In the case where the termination of the movement operation is detected by the detection section 110, the display control section 130 of an information processing apparatus 100I performs control such that the predetermined second display H1, H2 on the display region 141 is hidden. As for the timing at which the predetermined second display H1, H2 on the display region 141 is hidden, there are assumed various timings, which will be described below.
[1-8. Disabling Operation at Stage in which Edge of Display Object Reaches Display Region]
FIG. 8 is a diagram showing a screen example displayed by a general information processing apparatus in a case where a movement operation is performed at a stage in which the edge DT of the display object has already reached the display region 141. A general information processing apparatus 900A displays a part of the display object DB3 on the display region 141, and the edge DT (upper edge) of the display object DB3 has already reached the edge (upper edge) of the display region 141. When the movement operation in the downward direction is performed in this state, for example, although an information processing apparatus 900B recognizes the movement operation, the display object DB3 cannot be moved any farther.
However, unless outputting the fact that the display object DB3 cannot be moved any farther, it is difficult for the user to grasp the reason why the movement operation in the downward direction is disabled. Accordingly, when the movement operation in a direction corresponding to that in which the edge of the display object enters inside the display region 141 is further performed in the state where the edge of the display object has already reached the edge of the display region, the information processing apparatus 100 according to the embodiment of the present disclosure performs a predetermined second display.

FIG. 9 is a diagram illustrating a ca where the movement operation is performed at the stage in which the edge DT of the display object has already reached the display region 141. The display control section 130 of an information processing apparatus 100L displays a part of the display object DB3 on the display region 141, and the edge DT (upper edge) of the display object DB3 has still not reached the edge (upper edge) of the display region 141 at this stage.
The display object DB3 is moved by the movement operation performed by the operating object OP, and the display control section 130 of an information processing apparatus 100M displays a part of the display object DB3 on the display region 141, and the edge DT (upper edge) of the display object DB3 reaches the edge (upper edge) of the display region 141 at this stage. Here, an operation of attempting to move the display object in a direction in which the display object cannot be moved any farther is referred to a Overdrag, and an Overdrag-start point represents a position on the display object that is specified by the operating object OP at the point of starting the operation.
When the Overdrag is performed by the operating object OP, the display control section 130 of an information processing apparatus 100N displays the display object DB3 on the display region 141 at the same position as the position at which the display control section 130 of the information processing apparatus 100M displayed the display object DB3 on the display region 141. This is because the display object DB3 cannot be moved any farther. Here, a position on the display object that is specified by the operating object OP at the end of the Overdrag is referred to as operation point.
The display control section 130 of an information processing apparatus 100O also displays the display object DB3 on the display region 141 at the same position as the position at which the display control section 130 of the information processing apparatus 100M displayed the display object DB3 an the display region 141. In the case of detecting that the operating object OP is moved away from the position detection plane, the display control section 130 of the information processing apparatus 100O can perform control such that the predetermined second display is hidden.

The display control section 130 of an information processing apparatus 100P displays a part of the display object DB3 on the display region 141, and, since the edge DT (upper edge) of the display object DB3 has already reached the edge (upper edge) of the display region 141 at this stage, performs control such that a predetermined second display J1 is shown on the display region 141.
In the case where, while the movement operation is being performed, the operating object OP is positioned in a range exceeding a predetermined angle with respect to the movement direction on the basis of the Overdrag-start point detected by the detection section 110, the display control section 130 of an information processing apparatus 100Q cat perform control such that the predetermined second display J1 on the display region 141 is hidden. The case where the operating object OP is positioned in the range exceeding the predetermined angle with respect to the movement direction on the basis of the Overdrag-start point detected by the detection section 110 represents a case where an angle between the direction from the Overdrag-start point to the operation point and the movement direction exceeds the predetermined angle.
Further, as described above, in the case of detecting that the operating object OP is moved away from the position detection plane, the display control section 130 of an information processing apparatus 100R can perform control such that the predetermined second display is hidden. In the case where, while the movement operation is being performed, the operating object OP is positioned in a range that does not exceed the predetermined angle with respect to the movement direction on the basis of the Overdrag-start point detected by the detection section 110, the display control section 130 of an information processing apparatus 100S can perform control such that the predetermined second display J1 is shown on the display region 141.

In the case of determining that the operation is currently during the Overdrag (“Yes” in Step S202), the determination section 120 determines whether the operation performed in the immediately preceding processing flow detected by the detection section 110 was also the Overdrag (Step S205).
In the case of determining that the operation performed in the immediately preceding processing flow detected by the detection section 110 was not the Overdrag (“No” in Step S205), the determination section 120 replaces the Overdrag-start point with current coordinates detected by the detection section 110 (Step S206), and returns to Step S201. In the case of determining that the operation performed in the immediately preceding processing flow detected by the detection section 110 was the Overdrag (“Yes” in Step S205), the determination section 120 determines whether the operation point is present within a predetermined range (Step S207). The predetermined range represents the range that does not exceed the predetermined angle with respect to the movement direction on the basis of the Overdrag-start point.
In the case of determining that the operation point is not present within the predetermined range (“No” in Step S207), the determination section 120 proceeds to Step S204. In the case where it is determined by the determination section 120 that the operation point is present within the predetermined range (“Yes” in Step S207), the display control section 130 updates Overdrag-drawing (Step S208) and returns to Step S201. The updating of the Overdrag-drawing mans that control is performed such that the predetermined second display is shown.

FIGS. 37 and 38 are each a diagram showing a screen example displayed by the information processing apparatus 100 according to the embodiment of the present disclosure, obtained by performing the movement operation before the edge DT1 of the display object reaches the display region 141 and after the edge DT1 of the display object reached the display region 141. While the edge DT1 of the display object does not reach display region 141, the display control section 130 of an information processing apparatus 100c1 performs control such that the predetermined second display that is different from the predetermined first display is not shown an the display region 141 yet.
When the movement operation performed by the operating object OP is detected by the detection section 110, the display control section 130 of an information processing apparatus 100c2 performs control such that the predetermined second display that is different from the predetermined first display is not shown on the display region 141 yet, until the edge DT1 of the display object reaches the display region 141.
In the case where the movement operation performed by the operating object OP is detected by the detection section 110 when the edge DT1 of the display object has already reached the edge of the display region 141 corresponding to the edge DT1 of the display object, the display control section 130 of an information processing apparatus 100c3 performs control such that the predetermined second display that is different from the predetermined first display is shown on the display region 141. In the example shown in FIG. 37, the display control section 130 of the information processing apparatus 100c3 performs the control such that the predetermined second display is shown, by changing the shapes of items which re determined based on the edge DT1 of the display object and the position of the operating object OP detected by the detection section 110.
In the example shown in FIG. 37, the display control section 130 of the information processing apparatus 100c3 changes the shapes of the items “Action” and “Adventure” by lengthening the items in the movement direction. When a elongation amount of an display object DB5 (total of elongation amounts of respective items) is represented by M, and a movement distance of the operating object OP in the movement direction in the case where the movement operation is performed at the stage in which the edge DT1 of the display object has already reached the display region 141 is represented by L, the display control section 130 of the information processing apparatus 100c3 can lengthen the display object DB5 based on M, which is determined as shown in the following Equation 2, for example.

M=β×L  (Equation 2)

Here, β represents a constant value, the value thereof is not particularly limited, and may be 3/10(=0.3), for example.
Further, it is assumed that M changes based on the change in L, there may be set an upper limit Mmax for M. When the length of the display region 141 in the movement direction is represented by N, the display control section 130 of the information processing apparatus 100c3 can lengthen the display object DB5, using Mmax, which is determined as shown in the following Equation 3, as the upper limit of the elongation amount of the display object DB5.

Mmax=α×N  (Equation 3)

Here, α represents a constant value, the value thereof is not particularly limited, and may be 1⁄3, for example.
As shown in FIG. 38, in the case where a movement operation (for example, upward direction), which is a direction opposite to an elongation direction, is detected, the display control section 130 of an information processing apparatus 100c4 can perform control such that the elongation of the display object DB5 is cancelled, thereby hiding the predetermined second display on the display region 141. In the example shown in FIG. 38, every time a movement operation in the direction (for example, upward direction) which cancels the elongation is detected, the display control section 130 of the information processing apparatus 100c4 cancels the elongation of the display object DB5 for the movement distance based on the movement operation.
In the example shown in FIG. 38, the display control section 130 of the information processing apparatus 100c3 lengthens the display object DB5 in the elongation direction (for example, downward direction) for the length corresponding to M. Therefore, every time the movement operation in the direction opposite to the elongation direction is detected, the display control section 130 of the information processing apparatus 100c4 can cancel the elongation for the movement distance based on the movement operation, until the elongation amount of the display object DB5 becomes zero.
In the case where the movement operation in the direction (for example, upward direction), which is a direction opposite to the elongation direction, is detected after the elongation amount of the display object DB5 became zero, the display control section 130 of an information processing apparatus 100c5 can move the display object DB5 in the direction opposite to the elongation direction for the movement distance based on the movement operation.
[1-16. Screen Displayed by Operation after Edge of Display Object Reached Display Region]
FIG. 39 is a diagram showing a screen example displayed by the information processing apparatus 100 according to the embodiment of the present disclosure, obtained by performing the movement operation after the edge DT1 of the display object reached the display region 141. As shown in FIG. 39, in the same manner as in the case shown in FIG. 38, the display control section 130 of the information processing apparatus 100c3 performs control such that the predetermined second display is shown, by changing the shape of an item which is determined based on the edge DT1 of the display object and the position of the operating object OP detected by the detection section 110.
The display control section 130 of an information processing apparatus 100c6 can lengthen the display object DB5 based on M, which is determined as shown in the above Equation 2, for example. However, in the case where the upper limit Mmax is set for M, the display control section 130 of the information processing apparatus 100c6 cannot lengthen the display object DB5 in excess of Mmax, which is determined as shown in the above Equation 3.
Accordingly, in the case where the elongation amount M of the display object DB5 reaches a predetermined amount (for example, Mmax), the display control section 130 of an information processing apparatus 100c7 may perform automatic reduction of the display object DB5. That is, in the case where the elongation amount M of the display object DB5 reaches the predetermined amount (for example, Mmax), the display control section 130 of the information processing apparatus 100c7 may perform control such that the elongation of the display object DB5 is cancelled (may perform control such that the elongation amount M of the display object DB5 is brought back to zero).
FIG. 40 is a diagram showing a screen example displayed by the information processing apparatus 100 according to the embodiment of the present disclosure, obtained by performing the movement operation after the edge DT1 of the display object reached the display region 141. As shown in FIG. 40, in the same manner as in the case shown in FIG. 38, the display control section 130 of the information processing apparatus 100c3 performs control such that the predetermined second display is shown, by changing the shape of an item which is determined based on the edge DT1 of the display object and the position of the operating object OP detected by the detection section 110.
Subsequently, let us assume that the detection section 110 of an information processing apparatus 100c8 detects the termination of the movement operation. In that case, the display control section 130 of the information processing apparatus 100c7 may perform automatic reduction of the display object DB5. That is, in the case where the detection section 110 detects the termination of the movement operation, the display control section 130 of the information processing apparatus 100c7 may perform control such that the elongation of the display object DB5 is cancelled (may perform control such that the elongation amount M of the display object DB5 is brought back to zero).
It is assumed that there are various techniques for the display control section 130 to perform the automatic reduction of the display object DB5. For example, when V(t) represents a length of the display object DB5 at time t, VEND represents a terminal value of the length of the display object DB5, VSTART represents initial value of the length of the display object DB5, tDURATION represents time required for the automatic reduction, and γ represents an attenuation parameter, the display control section 130 can reduce the length of the display object DB5 based on V(t), which is determined as shown in the following Equation 4.

V(t)=(VEND−VSTART)×(1.0−(1.0−t/tDURATION)2×γ)+VSTART  (Equation 4)

[1-17. Another Example of Case where Edge of Display Object Reaches Display Region at End of Flick]
FIGS. 41 to 43 are each a diagram illustrating another example of the operation of the information processing apparatus 100 according to the embodiment of the present disclosure in the case where the edge of the display object reaches the display region at the end of the flick. As shown in FIG. 41, an information processing apparatus 100W1 causes a part of the display object DB3 to be displayed on the display region 141. When the flick operation in the upward direction is performed by the operating object OP in this state, it is assumed that the following corresponds to a region DR3 (i.e., a portion of the display object DB3) that is displayed on the display region 141 at the end of the flick operation in theory: a region within the display object DB3 obtained by proceeding the distance corresponding to the intensity of the flick operation from the region displayed on the display region 141, in the downward direction of the display object DB3.
As shown in FIG. 41, at the end of the flick, although the display control section 130 of an information processing apparatus 100W2 attempts to cause the region DR3 to be displayed as the display region 141, which is to be displayed on the display region 141 at the end of the flick in theory, the display control section 130 of the information processing apparatus 100W2 cannot cause the region DR3 to be displayed, because the edge DT (lower edge) of the display object DB3 passes through the edge (lower edge) of the display region 141. The determination on whether the edge DT (lower edge) of the display object DB3 passes through the edge (lower edge) of the display region 141 is performed by the determination section 120 as described above.
In the case where the determination section 120 determines that the edge DT of the display object passes through the edge of the display region 141 corresponding to the edge DT of the display object by the movement of the display object DB3 caused by the flick operation, the display control section 130 of the information processing apparatus 100W2 can cause a put or all of the display object DB3 to be lengthened after the edge DT of the display object DB3 reached the edge of the display region 141 corresponding to the edge DT of the display object DB3. The display control section 130 of the information processing apparatus 100W2 may cause the lengthened display object DB3 to be displayed an the display region 141, for example. In FIG. 41, there is shown an example in which the display control section 130 of the information processing apparatus 100W2 performs control such that the item “Thriller”, which is the nearest item from the edge DT (lower edge) of the display object DB3, is lengthened, and the lengthened display object DB3 is displayed on the display region 141.
After the elapse of a predetermined time period from the control of displaying the lengthened display object DB3 on the display region 141, the display control section 130 of an information processing apparatus 100W3 may perform control such that, as shown in FIG. 42, the display object DB3 whose elongation is cancelled is displayed on the display region 141. In FIG. 42, there is shown an example in which the display control section 130 of the information processing apparatus 100W3 performs control such that the display object DB3 in which the elongation of the item “Thriller” is cancelled is displayed on the display region 141, after the elapse of the predetermined time period.
As shown in FIG. 42, an information processing apparatus 100W4 causes a part of the display object DB3 to be displayed on the display region 141. When the flick operation in the downward direction is performed by the operating object OP in this state, it is assumed that the following corresponds to a region DR4 that is displayed on the display region 141 at the end of the flick operation in theory: a region within the display object DB3 obtained by proceeding the distance corresponding to the intensity of the flick operation from the region displayed on the display region 141, in the upward direction of the display object DB3.
As shown in FIG. 43, at the end of the flick, although the display control section 130 of an information processing apparatus 100W5 attempts to cause the region DR4 to be displayed on the display region 141, which is to be displayed on the display region 141 at the end of the flick in theory, the display control section 130 of the information processing apparatus 100W5 cannot cause the region DR4 to be displayed, because the edge DT (upper edge) of the display object DB3 reaches the edge (upper edge) of the display region 141. In this case, the display control section 130 of the information processing apparatus 100W5 may cause the lengthened display object DB3 to be displayed on the display region 141, for example. In FIG. 43, there is shown an example in which the display control section 130 of the information processing apparatus 100W5 performs control such that “Action”, which is the nearest item from the edge DT (upper edge) of the display object DB3, “Adventure”, which is the second nearest item, and “Animation”, which is the third nearest item, are lengthened, and the lengthened display object DB3 is displayed on the display region 141.
Note that the number of items to be lengthened by the display control section 130 is not particularly limited. For example, the display control section 130 may not lengthen the item based on the velocity of the flick operation, but may lengthen in the same amount each of a predetermined number of items counted from the nearest item from the edge DT of the display object DB3, or may lengthen the items such that the nearer the item is from the edge DT of the display object DB3, the larger the extent to which the item is lengthened. Further, for example, the display control section 130 may lengthen in the same amount the items counted from the nearest item from the edge DT of the display object DB3, or may lengthen the items such that the nearer the item is from the edge DT of the display object DB3, the larger the extent to which the item is lengthened, the number of items being determined in accordance with the velocity of the flick operation.
After the elapse of a predetermined time period from the control of displaying the lengthened display object DB3 on the display region 141, the display control section 130 of an information processing apparatus 100W6 may perform control such that, as shown in FIG. 43, the display object DB3 whose elongation is cancelled is displayed on the display region 141. In FIG. 43, there is shown an example in which the display control section 130 of the information processing apparatus 100W6 performs control such that the display object DB3 in which the elongation of the items “Action”, “Adventure”, and “Animation” is cancelled is displayed on the display region 141, after the elapse of a predetermined time period.
[1-18. Operation in Cue where Drag Operation (in X- and Y-Axis Directions) is Performed]
FIG. 44 is a flowchart showing a flow of an operation (when the display object can be moved in the X-axis direction and in the Y-axis direction) performed by the information processing apparatus according to the embodiment in the case where the drag operation is performed. As shown in FIG. 44, the determination section 120 determines whether the operation detected by the detection section 110 is dragging (Step S301). In the cue of determining that the operation detected by the detection section 110 is not dragging (“No” in Step S301), the determination section 120 determines whether the operation performed in the immediately preceding processing flow detected by the detection section 110 was the Overdrag (Step S302). In the case where the determination section 120 determines that the operation performed in the immediately preceding processing flow detected by the detection section 110 was not the Overdrag (“No” in Step S302), the display control section 130 returns to Step S301. In the case where the determination section 120 determines that the operation performed in the immediately preceding processing flow detected by the detection section 110 was the Overdrag (“Yes” in Step S302), the display control section 130 performs control such that Fadeout-drawing, in which the predetermined second display is gradually hidden, is executed (Step S303), and returns to Step S301.
In the case of determining that the operation detected by the detection section 110 is dragging (“Yes” is Step S301), the determination section 120 determines whether the operation is currently during the Overdrag in the X-direction (Step S304). In the case of determining that the operation is currently not during the Overdrag in the X-direction (“No” in Step S304), the determination section 120 determines whether the operation is currently during the Overdrag in the Y-direction (Step S312). In the case of determining that the operation is currently not during the Overdrag in the Y-direction (“No” in Step S312), the determination section 120 proceeds to Step S302.
In the cue of determining that the operation is currently during the Overdrag in the Y-direction (“Yes” in Step S312), the determination section 120 determines whether the operation performed in the immediately preceding processing flow was also the Overdrag in the Y-direction (Step S313). In the case of determining that the operation performed in the immediately preceding processing flow was also the Overdrag in the Y-direction (“Yes” in Step S313), the determination section 120 determines whether the operation is currently during the Overdrag in the X-direction (Step S315). In the case of determining that the operation performed in the immediately preceding processing flow was not the Overdrag in the Y-direction (“No” in Step S313), the determination section 120 replaces the Overdrag-start point in the Y-direction with a current Y coordinate detected by the detection section 110 (Step S314), and proceeds to Step S315.
The determination section 120 determines whether the operation is currently during the Overdrag in the X-direction (Step S315). In the case of determining that the operation is currently not during the Overdrag in the X-direction (“No” in Step S315), the determination section 120 updates Overdrag-drawing in the Y-direction (Step S318) and returns to Step S301. The updating of the Overdrag-drawing in the Y-direction means that control is performed such that the predetermined second display is shown in the Y-direction.
In the case of determining that the operation is currently during the Overdrag in the X-direction (“Yes” in Step S315), the determination section 120 determines whether the operation performed in the immediately preceding processing flow was also the Overdrag in the X-direction (Step S316). In the case of determining that the operation performed in the immediately preceding processing flow was also the Overdrag in the X-direction (“Yes” in Step S316), the determination section 120 updates Overdag-drawing in the XY-directions (Step S311) and returns to Step S301. The updating of the Overdag-drawing in the XY-directions means that control is performed such that the predetermined second display is shown in the XY-directions.
In the case of determining that the operation performed in the immediately preceding processing flow was not the Overdrag in the X-direction (“No” in Step S316), the determination section 120 replaces the Overdrag-start point in the X-direction with a current X coordinate detected by the detection section 110 (Step S317), and proceeds to Step S311. In the case of determining that the operation is currently during the Overdrag in the X-direction (“Yes” in Step S304), the determination section 120 carries out processing in the X-direction in the same manner as in the case of “Yes” in Step S312.
