2. Operation Example of Scroll Operation Processing Unit 14 Next, an operation example of the scroll operation processing unit 14 including the fixed region determination processing unit 15, the fixed region display processing unit 16, and the non-fixed region display processing unit 17 will be described with reference to FIGS. This will be described with reference to FIG. FIG. 2 is an explanatory diagram illustrating an example of a state before and after the display division between the fixed area F and the non-fixed area NF in the first embodiment. FIG. 2 shows an example in which the document creation application is operating in the state A and the state B. FIG. 3 is an explanatory diagram illustrating another example of the state before and after the display division between the fixed area F and the non-fixed area NF in the first embodiment. FIG. 3 is an example in which the image browsing application is operating in the state C, the state D, and the state E. FIG. 4 is an explanatory diagram illustrating still another example of a state before and after the division of the fixed region F and the non-fixed region NF in the first embodiment. FIG. 4 is an example in which the map browsing application is operating in the state F, the state G, and the state H. Each of the images shown in FIGS. 2 to 4 is displayed on the display screen of the display unit 5 of the mobile phone 10.

  For example, as shown in state A in FIG. 2, first, the user's middle finger (first finger) touches a certain position (first contact point) in the display screen once, and then continues in state B in FIG. In this way, it is assumed that a touch input operation is performed in which the index finger (second finger) touches a position (second contact point) different from the middle finger and is dragged a predetermined distance vertically downward. In this case, the fixed area determination processing unit 15 determines the range AR of the predetermined rectangular area including the first contact point touched by the middle finger in the state A as the fixed area F for the information displayed on the display screen of the display unit 5. The display area including the second contact point touched by the index finger in the state B and excluding the fixed area F in the entire display screen is determined to be NF outside the fixed area. The size of the predetermined area AR of the rectangular area is preferably specified in advance in the operation of the fixed area determination processing unit 15 or the information storage medium 25. For example, a part of the area AR of the rectangular area shown in the state B The size of the range may be acceptable. Further, the scrolling of the images displayed on the display screen of the display unit 5 other than the fixed image is performed in advance by a predetermined distance dragged by the user's index finger touching the second contact point. It is assumed that the determination is performed when the operation of the determination processing unit 15 or the information storage medium 25 exceeds a predetermined threshold value. The same applies to the following embodiments. The fixed area determination processing unit 15 vertically lowers the scroll direction according to the position of the second contact point of the second finger with respect to the display screen of the display unit 5 and the drag direction and distance of the index finger that is the second finger. The direction is determined, and information related to the scroll direction is output to the non-fixed-region display processing unit 17.

  The fixed area display processing unit 16 is the same as the image in the range AR of the predetermined rectangular area when the first contact point by the touch of the middle finger is detected in the state B as the fixed image displayed in the display area of the fixed area F. Or a predetermined enlarged or reduced image is generated.

  The display area 17 outside the fixed area is a display area excluding the fixed area F in the entire display screen including the second contact point touched by the index finger in the state B as a scrolled image displayed in the display area outside the fixed area NF. An image obtained by scrolling an image of a certain non-fixed area NF in the vertically downward direction, which is the scroll direction determined by the fixed area determination processing unit 15, is generated. Thereby, regarding the scroll bar 201 shown in the state A, the scroll bar is not displayed in the fixed region F in the state B, and only the scroll bar 202 in the non-fixed region NF in the state B is displayed.

  Also, for example, first, as shown in state C of FIG. 3, the user's first finger touches a certain position in the display screen (first contact point; see the X in the figure) once, and then Assume that a touch input operation is performed in which the second finger touches a position (second contact point) different from that of the middle finger and drags a predetermined distance in the horizontal left direction. In this case, the fixed area determination processing unit 15 determines the range AR of the predetermined rectangular area including the first contact point touched by the middle finger in the state C as the fixed area F, as shown in the state D. A display area including the second contact point touched by the two fingers and excluding the fixed area F in the entire display screen is determined as an NF outside the fixed area. In the description of FIG. 3, the information storage medium 25 of the mobile phone 10 includes a flower bed image (image ID = 1), a building image (image ID = 2), an animal image (image ID = 3), and a window image (image). ID = 4), night scene image (image ID = 5), and stationery image (image ID = 6) are stored in advance in this order.

  The fixed area display processing unit 16 uses, as a fixed image to be displayed in the display area of the fixed area F, the flower bed image when the first contact point by the touch of the first finger is detected in the state C as the range AR of the rectangular area. A flower bed image reduced so that the entire flower bed image can be displayed is generated (see state D). In addition, the fixed area display processing unit 16 displays the fixed image displayed in the display area of the fixed area F as the rectangular area in the flower bed image when the first contact point by the touch of the first finger is detected in the state C. A flower bed image having the same size as that in the range AR may be extracted from an arbitrary place of the flower bed image and generated.

  The non-fixed area display processing unit 17 excludes the display area of the fixed area F from the entire display screen including the second contact point touched by the index finger in the state C as a scrolled image displayed in the display area of the non-fixed area NF. A building image is generated by scrolling the flower bed image displayed on the non-fixed area NF in the horizontal left direction which is the scroll direction determined by the fixed area determination processing unit 15.

  Furthermore, in the state D in which the flower bed image is displayed as the fixed image and the building image is displayed as the scrolled image, the touch of the first finger is kept fixed and the second finger is newly continued in the left direction. It is assumed that a touch input operation of dragging a predetermined distance three times is performed. In this case, the fixed area determination processing unit 15 determines that the fixed area F of the display screen is not changed because the first finger touch on the first contact point in the state D is fixed and maintained, and the first area in the state D is not changed. The display area including the second contact point touched by the two fingers and excluding the fixed area F in the entire display screen is determined as an NF outside the fixed area for the image displayed on the display screen of the display unit 5. The fixed area determination processing unit 15 determines the scroll direction as the horizontal left direction according to the position of the second contact point of the second finger on the display screen of the display unit 5, the drag direction and the distance of the second finger. Then, information related to the scroll direction is output to the outside fixed area display processing unit 17.

  The fixed area display processing unit 16 determines that the fixed area F is not changed by the fixed area determination processing unit 15, so that the flower bed image that is the current fixed image is generated as it is without generating a new fixed image. To the unit 18.

  The fixed area outside display processing unit 17 excludes the fixed area F from the entire display screen including the second contact point touched by the second finger in the state D as a scrolled image to be displayed in the display area outside the fixed area NF. A night view image is generated by scrolling the three image data by dragging the building image displayed in the non-fixed area NF three times in the horizontal left direction which is the scroll direction determined by the fixed area determination processing unit 15 ( (See state E in FIG. 3).

  The non-fixed-region display processing unit 17 is an image that is scrolled by an amount corresponding to the position of the second contact point of the second finger with respect to the display screen of the display unit 5 and the drag direction and distance of the index finger that is the second finger. For example, when the drag operation three times in the horizontal left direction is a scroll amount of one image half, a window image half and a night view image half may be generated. In this case, it is preferable that the relationship between the drag distance and the scroll amount of the image is defined in advance in the operation of the non-fixed area display processing unit 17 or the information storage medium 25.

  Also, for example, first, as shown in state F of FIG. 4, the user's first finger touches a certain position in the display screen (first contact point; see the X in the figure) once, and then the first It is assumed that a touch input operation is performed in which the second finger touches a position (second contact point) different from the first finger and is dragged a predetermined distance diagonally downward to the right. In this case, as shown in the state G, the fixed region determination processing unit 15 displays a predetermined rectangular region range AR including the first contact point touched by the first finger in the state F on the display screen of the display unit 5. The display area including the second contact point touched by the second finger in the state F and excluding the display area of the fixed area F is determined as the non-fixed area NF. judge. The fixed area determination processing unit 15 determines that the scroll direction is a diagonally lower right direction according to the position of the second contact point of the second finger with respect to the display screen of the display unit 5, the drag direction and the distance of the second finger. Then, information related to the scroll direction is output to the outside fixed area display processing unit 17.

  The fixed area display processing unit 16 extracts the map image when the first contact point by the touch of the first finger in the state F is detected as the fixed image to be displayed in the display area of the fixed area F, and extracts the rectangular area A map image corresponding to the size in the range AR is generated.

  The fixed area outside display processing unit 17 excludes the fixed area F from the entire display screen including the second contact point touched by the second finger in the state F as a scrolled image to be displayed in the display area outside the fixed area NF. A map image is generated by scrolling the map image displayed on the non-fixed area NF in the diagonally lower right direction, which is the scroll direction determined by the fixed area determination processing unit 15.

  Furthermore, a map image surrounded by a predetermined area AR of a rectangular area is displayed as a fixed image, and a map displayed as a scrolled image in the state NF outside the fixed area is scrolled diagonally to the lower right. Assume that in the state G in which an image is displayed, a touch input operation is performed in which the touch of the middle finger is fixed and the index finger is newly dragged a predetermined distance in the diagonally lower right direction. In this case, the fixed area determination processing unit 15 determines that the fixed area F of the display screen does not change because the first finger touch on the first contact point in the state G is fixed and maintained, and the state G The display area including the second contact point touched by the second finger and excluding the fixed area F in the entire display screen is determined as NF outside the fixed area. The fixed area determination processing unit 15 determines the scroll direction as the horizontal left direction according to the position of the second contact point of the second finger on the display screen of the display unit 5, the drag direction and the distance of the second finger. Then, information related to the scroll direction is output to the outside fixed area display processing unit 17.

  The fixed area display processing unit 16 determines that the fixed area F is not changed by the fixed area determination processing unit 15, so that the map image which is the current fixed image is generated as it is without generating a new fixed image. To the unit 18.

  The non-fixed area display processing unit 17 excludes the fixed area F from the entire display screen including the second contact point touched by the second finger in the state G as a scrolled image displayed in the display area of the non-fixed area NF. A map image is generated by scrolling the map image displayed on the non-fixed area NF in the diagonally lower right direction, which is the scroll direction determined by the fixed area determination processing unit 15 (see state H in FIG. 4).

3. Description on Operation of Mobile Phone 10 of First Embodiment FIGS. 5 and 6 are flowcharts showing the operation of the mobile phone 10 of the first embodiment. In the following description, it is assumed that an arbitrary image is displayed in advance on the display screen of the display unit 5 of the mobile phone 10.

  In FIG. 5, the operation content determination processing unit 12 determines whether or not a touch input operation in which the first finger of the user touches the display screen of the display unit 5 has been performed (S1). When it is determined that the touch input operation has been performed in step S1, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S2).

  The initial flag “1” indicates a state in which only the first finger touches the display screen of the display unit 5. When the initial flag is “0”, the user's finger does not touch the display screen of the display unit 5 at all, or the first finger touches and the second finger has already touched and dragged. Indicates the state. The description regarding the initial flag is the same in the following embodiments.

  The operation content determination processing unit 12 determines whether or not a touch input operation is performed in which the second finger touches the display screen of the display unit 5 following the touch of the first finger determined in step S1. (S3). When it is determined that the touch input operation is performed in step S3, the operation content determination processing unit 12 touches the display screen of the display unit 5 with the second finger and then drags the predetermined distance in a predetermined direction. It is determined whether or not has been performed (S4). The predetermined direction includes any one of the horizontal left direction, the horizontal right direction, the vertical upward direction, the vertical downward direction, and the diagonal direction, and the same applies to the following description.

  When it is determined that the touch input operation is performed in step S4, the operation content determination processing unit 12 obtains information on the coordinate change amount (ΔX2, ΔY2) of the second contact point dragged based on the touch input operation. Obtaining and writing information of the coordinate change amount in the information storage medium 25 (S5). Note that the operation content determination processing unit 12 has the coordinates before dragging (X2s, Y2s) and the coordinates after dragging of the second contact point (X2e) when the second finger touches the display screen of the display unit 5. , Y2e), the coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired by acquiring the information of the coordinate change amount (ΔX2, ΔY2) of the second contact point.

  After the coordinate change amount (ΔX2, ΔY2) information of the second contact point is acquired in step S5, in FIG. 6, the operation content determination processing unit 12 determines whether or not the second finger drag is the first drag. That is, it is determined whether or not the initial flag is “1” (S6). When it is determined that the drag of the second finger is the first drag, the fixed area determination processing unit 15 coordinates the second contact point with the display screen of the display unit 5 by the second finger, and the second contact. In accordance with the drag direction and distance from the point, it is displayed on the NF outside the fixed area including the second contact point and excluding the predetermined fixed area F including the first contact point from the entire display screen of the display unit 5. The scroll direction with respect to the image is determined (S7).

  Note that the fixed area determination processing unit 15 is based on the coordinates of the second contact point on the display screen of the display unit 5 and the coordinate change amount (ΔX2, ΔY2) of the second contact point acquired in step S5. It is preferable to determine the scroll direction of the image of the non-fixed area NF including the second contact point. For example, when ΔX2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the vertical direction. When ΔY2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the horizontal direction. In addition, when ΔX2 and ΔY2 of the coordinate change amounts (ΔX2, ΔY2) of the second contact point are not substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is an oblique direction.

  When it is determined that the scroll direction in step S7 is an oblique direction, the fixed area determination processing unit 15 performs an oblique direction with respect to the image of the non-fixed area NF including the second contact point in response to the drag of the second finger. The predetermined rectangular area including the first contact point is determined as the fixed area F (S8). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S8).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S8). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = oblique direction” in the information storage medium 25 (S9).

  When it is determined in step S7 that the scroll direction is only the horizontal direction, the fixed area determination processing unit 15 is horizontal with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S10). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S10).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S10). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S11).

  When it is determined that the scroll direction in step S7 is only the vertical direction, the fixed area determination processing unit 15 is vertical to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S12). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S12).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S12). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S13).

  After the scroll flag is written in the information storage medium 25 in step S9, step S11, or step S13, the operation content determination processing unit 12 writes information indicating that “initial flag = 0” in the information storage medium 25. Then, the information of the initial flag is updated (S14).

  After the information of the initial flag is updated in step S14, in FIG. 5, the out-of-fixed-region display processing unit 17 drags the second finger according to the scroll flag stored in the information storage medium 25 (S15). A scrolled image obtained by scrolling the image displayed immediately before the non-fixed area NF in the scroll direction determined by the fixed area determination processing unit 15 is generated and displayed (S16 to S18).

  Specifically, when the scroll flag is in an oblique direction, the fixed area outside display processing unit 17 scrolls the image displayed in the fixed area outside NF immediately before dragging the second finger in the oblique direction. A generated image is generated, and the generated scrolled image is output to the display image generating unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S16).

  In addition, when the scroll flag is in the horizontal direction, the out-of-fixed-area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the out-of-fixed area NF in the horizontal direction immediately before dragging the second finger. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S17).

  Further, when the scroll flag is in the vertical direction, the out-of-fixed-region display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the out-of-fixed region NF in the vertical direction immediately before the second finger is dragged. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S18).

  When the first finger of the user is touching the fixed area and the second finger touches outside the fixed area and is newly dragged by a predetermined distance in the predetermined direction, the above-described steps S5 to S5 are performed. The operation of S18 is repeated.

  As described above, the mobile phone 10 according to the first embodiment displays a predetermined rectangular area including the first contact point touched by the first finger on the image displayed on the display screen of the display unit 5. The fixed area F of the entire image is determined, and the display area excluding the fixed area F of the entire image including the second contact point touched by the second finger is determined to be NF outside the fixed area.

  Further, the mobile phone 10 generates a fixed image of a predetermined rectangular area determined as the fixed area F, and displays the image displayed in the display area determined as NF outside the fixed area on the display screen of the display unit 5. A scrolled image is generated that is scrolled in the scroll direction determined according to the coordinates of the second contact point and the drag direction and distance of the second finger. The mobile phone 10 displays a synthesized image obtained by synthesizing the generated fixed image and the scrolled image on the display screen of the display unit 5.

  Therefore, according to the mobile phone 10 of the first embodiment, a part of the content displayed on the display screen is fixed and a fixed portion of the display screen is fixed according to an intuitive and simple operation. You can scroll other areas that are not covered. For this reason, the user can intuitively and simply perform finger scrolling and dragging on the scroll direction of the image displayed on the display screen of the display unit 5 in the fixed portion or the display divided portion, or the image displayed outside the fixed region NF. The selection of the fixed area F and the scrolling of the NF outside the fixed area can be easily realized by only the operation of at least two fingers.

(Second Embodiment)
4). Configuration of Mobile Phone 10a of Second Embodiment FIG. 7 is a block diagram showing an internal configuration of a mobile phone 10a that is an example of the electronic apparatus of the invention. As shown in FIG. 7, the mobile phone 10 a includes a display processing unit 13 a further including a scroll stop processing unit 21 and an inertial scroll determination processing unit 20 in the display processing unit 13 of the mobile phone 10 according to the first embodiment. Prepare. Since the configuration other than the scroll stop processing unit 21 and the inertial scroll determination processing unit 20 is the same as that of the mobile phone 10 of the first embodiment, a description of the same content is omitted.

  The definition of inertial scroll in each of the following embodiments will be described. When the user directly drags a document displayed on the display screen of the display unit 5 to change the display range on the display screen, it is not possible to perform a scroll larger than the size of the display screen at a time. For this reason, when the user scrolls a large-capacity document extensively, the user has to repeatedly drag the document on the display screen.

  Therefore, the operation of directly scrolling with a finger or a stylus pen becomes practical by flicking the document on the display screen with a finger so that the paper slides on a smooth desk. Yes. By flicking the display screen quickly with a finger touched on the display screen equipped with a touch panel or a stylus pen, the display screen is continuously scrolled in the paid direction, and the speed at which the display screen is paid The scroll for continuously changing the range of the display screen by defining the scroll speed is defined as “inertial scroll”. For inertial scrolling, when the scroll speed is defined according to the speed at which the display screen is paid, the scroll speed of the display screen is gradually changed as the scroll time elapses in addition to the case where the scroll speed is constant. It is also included in the case of (for example, decreasing or increasing).

  The inertial scroll determination processing unit 20 displays the display on the display unit 5 when the first finger touches the first contact point and the second finger touches the second contact point and drags the predetermined distance in the predetermined direction. It is determined whether inertial scrolling has been executed on the image displayed on the screen, or whether execution of inertial scrolling has been instructed. Note that when the execution of inertial scroll is instructed, the inertial scroll determination processing unit 20 determines information indicating that the touch input operation, which is the flick operation for executing the inertial scroll, has been performed. This is a case of obtaining from the processing unit 12.

  If the inertial scroll determination processing unit 20 determines that the execution of the inertial scroll for the image displayed on the display screen of the display unit 5 has been instructed, the inertial scroll flag (Inertia_Flg) = 1 is stored in the information storage medium 25. "Is written. Note that the inertia scroll flag is “1” indicates that the image displayed on the display screen of the display unit 5 is inertia scrolling. The inertia scroll flag “0” indicates a state in which the image displayed on the display screen of the display unit 5 is not inertial scrolled. Therefore, the inertial scroll determination processing unit 20 determines whether inertial scrolling is being executed according to the inertial scroll flag stored in the information storage medium 25.

When the inertia scroll flag is “1”, the inertia scroll determination processing unit 20 changes the coordinate when the second finger touching the second contact point drags from the second contact point in a predetermined direction by a predetermined distance. (ΔX2, ΔY2) and drag time (ΔT2) are acquired from the operation content determination processing unit 12. Furthermore, the inertial scroll determination processing unit 20 calculates the inertial scroll speed S1 based on the acquired coordinate change amounts (ΔX2, ΔY2) and the drag time (ΔT2). For example, the inertial scroll speed S1 can be calculated by the inertial scroll speed S1 = √ ((ΔX2) ² + (ΔY2) ² ) / ΔT2. The inertial scroll determination processing unit 20 outputs information on the calculated inertial scroll speed S1 to the out-of-fixed-region display processing unit 17. Note that the inertial scroll determination processing unit 20 may determine whether or not normal scrolling that is not inertial scrolling is executed based on the drag operation of the second finger. When it is determined that the normal scroll is not executed, the inertial scroll determination processing unit 20 displays information indicating “scroll flag = 0” indicating that the normal scroll is not executed as the information storage medium 25. It is preferable to memorize.

  When the inertial scroll determination processing unit 20 determines that the inertial scroll has already been executed, the scroll stop processing unit 21 causes the first finger and the second finger to display the display screen of the display unit 5, respectively. Stops the inertial scrolling when touched. The scroll stop processing unit 21 is configured such that the user's finger moves the display screen of the display unit 5 when the scrolled image displayed on the non-fixed area NF of the display screen of the display unit 5 does not perform normal scrolling or inertia scrolling. Is touched, it is determined whether the touching finger is the first finger or the second finger.

  The scroll stop processing unit 21 touches the display unit 5 with the first finger when the scrolled image displayed on the non-fixed area NF of the display screen of the display unit 5 is not performing normal scrolling or inertia scrolling. If it is determined that the fixed image and the scrolled image are separated, the fixed image touched by the first finger is displayed on the entire display unit 5. In addition, the scroll stop processing unit 21 allows only the second finger to move the display unit 5 when the scrolled image displayed on the non-fixed area NF of the display screen of the display unit 5 does not perform normal scrolling or inertia scrolling. When it is determined that the touch is made, the display divided state between the fixed image and the scrolled image is canceled, and the scrolled image touched by the second finger is displayed on the entire display unit 5.

  Note that the scroll stop processing unit 21 determines that the user's finger does not touch the display unit 5 at all when the scrolled image displayed on the display screen of the display unit 5 is not performing normal scrolling or inertia scrolling. If it has been done, a fixed image or a scrolled image is displayed on the display unit 5. In this case, it is preferable that whether the fixed image or the scrolled image is displayed on the display unit 5 is defined in advance in the operation of the scroll stop processing unit 21.

5. Operation Example of Inertial Scroll Determination Processing Unit 20 and Scroll Stop Processing Unit 21 Next, an operation example of the inertial scroll determination processing unit 20 and the scroll stop processing unit 21 will be described with reference to FIG. FIG. 8 is an explanatory diagram illustrating an example of a state before and after the display division between the fixed area F and the non-fixed area NF in the second embodiment. In FIG. 8, the image browsing application is operating in the state I, the state J, the state K, and the state L. The state J ′ will be described later. In addition, each image shown by FIG. 8 is displayed on the display screen of the display part 5 of the mobile telephone 10a. 8, the information storage medium 25 of the mobile phone 10 includes a flower bed image (image ID = 1), a building image (image ID = 2), an animal image (image ID = 3), a window Images (image ID = 4), night scene image (image ID = 5), and stationery image (image ID = 6) are stored in advance in this order.

  For example, in the state I of FIG. 8, it is assumed that the inertial scroll determination processing unit 20 determines that the inertial scroll is being executed in the horizontal left direction based on the flick operation described above. At this time, the information indicating that “inertia scroll flag = 1” is written in the information storage medium 25 by the inertia scroll determination processing unit 20. Therefore, in the state I in FIG. 8, the flower bed image is displayed as a fixed image corresponding to the fixed region F, and the night view image is out of the fixed region NF as the scrolled image at the moment when the inertial scroll is executed in the horizontal left direction. It is assumed that it is in the state displayed in.

  In such a state I, when the user's second finger touches any position outside the fixed area NF where the scrolled image is displayed on the display screen of the display unit 5, the scroll stop processing unit 21 The execution of the inertial scroll in the horizontal left direction being executed for the NF outside the fixed area is stopped (see state J). The scroll stop processing unit 21 displays the night view image displayed as the scrolled image at the moment when execution of the inertial scrolling in the horizontal left direction is stopped on the non-fixed region display processing unit 17 so as to display it on the non-fixed region NF. To instruct.

  The non-fixed area display processing unit 17 generates a scrolled image displayed in the display area of the non-fixed area NF based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

  In addition, for example, in the state I of FIG. 8, the inertial scroll determination processing unit 20 is in a state in which normal scrolling or inertial scrolling is not performed in the NF outside the fixed area of the display screen of the display unit 5 or the execution is stopped. Suppose that it is determined that it is in a state. At this time, the first finger touches the fixed area F including the first contact point, and the second finger touches the non-fixed area NF including the second contact point. Further, the information indicating that “inertia scroll flag = 0” is written in the information storage medium 25 by the inertia scroll determination processing unit 20. Therefore, state I in FIG. 8 is a state in which a flower bed image is displayed as a fixed image corresponding to the fixed region F, and a night view image is displayed as a scrolled image corresponding to the non-fixed region NF.

  In such a state I, when the second finger releases the touch on the non-fixed area NF, the scroll stop processing unit 21 performs the display division of the fixed area F and the non-fixed area NF on the display screen of the display unit 5. The fixed area outside display processing unit so that the flower bed image, which is a fixed image of the fixed area F touched by the remaining first finger touching the display unit 5, is displayed on the entire display unit 5. 17 (see state K).

  The non-fixed area display processing unit 17 generates a flower bed image, which is a fixed image displayed in the fixed area F, as a scrolled image based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

  In addition, for example, in the state I of FIG. 8, the inertial scroll determination processing unit 20 is in a state in which normal scrolling or inertial scrolling is not performed in the NF outside the fixed area of the display screen of the display unit 5 or the execution is stopped. Suppose that it is determined that it is in a state. At this time, the first finger touches the fixed area F including the first contact point, and the second finger touches the non-fixed area NF including the second contact point. Further, the information indicating that “inertia scroll flag = 0” is written in the information storage medium 25 by the inertia scroll determination processing unit 20. Therefore, state I in FIG. 8 is a state in which a flower bed image is displayed as a fixed image corresponding to the fixed region F, and a night view image is displayed as a scrolled image corresponding to the non-fixed region NF.

  In such a state I, when the first finger releases the touch on the fixed area F, the scroll stop processing unit 21 cancels the display division of the fixed area F and the non-fixed area NF on the display screen of the display unit 5. In addition, the outside of the fixed area display process is performed so that the night view image that is the scrolled image of the non-fixed area NF touched by the remaining second finger touching the display unit 5 is displayed on the entire display unit 5. The unit 17 is instructed (see state L).

  The non-fixed area display processing unit 17 generates a night scene image that is a scrolled image displayed on the non-fixed area NF based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

6). Description of Operation of Mobile Phone 10a of Second Embodiment FIGS. 9 to 12 are flowcharts showing the operation of the mobile phone 10a of the second embodiment. In the following description, it is assumed that an arbitrary image is displayed in advance on the display screen of the display unit 5 of the mobile phone 10a.

  In FIG. 9, the operation content determination processing unit 12 determines whether or not a touch input operation has been performed in which the first finger of the user touches the display screen of the display unit 5 (S21). When it is determined that the touch input operation is performed in step S21, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and information indicating that “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S22).

  The operation content determination processing unit 12 determines whether or not a touch input operation is performed in which the second finger touches the display screen of the display unit 5 following the touch of the first finger determined in step S21. (S23). If it is determined that the touch input operation is performed in step S23, the operation content determination processing unit 12 touches the display screen of the display unit 5 with the second finger and then drags the predetermined distance in a predetermined direction. Whether or not has been performed is determined (S24).

  When it is determined that the touch input operation is performed in step S24, the inertial scroll determination processing unit 20 determines whether or not the touch input operation is an operation for instructing execution of inertial scroll (S25).

  If it is determined in step S25 that the touch input operation is an operation for instructing execution of inertial scroll, the inertial scroll determination processing unit 20 stores information indicating that “inertia scroll flag (Inertia_Flg) = 1”. Writing to the medium 25 (S26). At this time, the inertial scroll determination processing unit 20 calculates the coordinate change amount (ΔX2, ΔY2) and the drag time (ΔT2) when the second finger drags a predetermined distance from the second contact point, and the operation content determination processing unit 12. (S27). Further, as described above, the inertial scroll determination processing unit 20 calculates the inertial scroll speed S1 based on the acquired coordinate change amounts (ΔX2, ΔY2) and the drag time (ΔT2) (S28).

  When it is determined that the touch input operation in step S24 is not an operation instructing execution of inertial scroll, the operation content determination processing unit 12 determines the second contact point dragged based on the touch input operation in step S24. Information on coordinate change amounts (ΔX2, ΔY2) is acquired, and information on the coordinate change amounts is written in the information storage medium 25 (S29).

  Note that the operation content determination processing unit 12 has the coordinates before dragging (X2s, Y2s) and the coordinates after dragging of the second contact point (X2e) when the second finger touches the display screen of the display unit 5. , Y2e), the coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired by acquiring the information of the coordinate change amount (ΔX2, ΔY2) of the second contact point.

  After the coordinate change amount (ΔX2, ΔY2) information of the second contact point is acquired in step S29, in FIG. 10, the operation content determination processing unit 12 determines whether or not the second finger drag is the first drag. That is, it is determined whether or not the initial flag is “1” (S30). When it is determined that the drag of the second finger is the first drag, the fixed area determination processing unit 15 coordinates the second contact point with the display screen of the display unit 5 by the second finger, and the second contact. In accordance with the drag direction and distance from the point, it is displayed on the NF outside the fixed area including the second contact point and excluding the predetermined fixed area F including the first contact point from the entire display screen of the display unit 5. The scroll direction with respect to the image is determined (S31).

  Note that the fixed area determination processing unit 15 is based on the coordinates of the second contact point on the display screen of the display unit 5 and the coordinate change amount (ΔX2, ΔY2) of the second contact point acquired in step S29. It is preferable to determine the scroll direction of the image of the non-fixed area NF including the second contact point. For example, when ΔX2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the vertical direction. When ΔY2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the horizontal direction. In addition, when ΔX2 and ΔY2 of the coordinate change amounts (ΔX2, ΔY2) of the second contact point are not substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is an oblique direction.

  When it is determined that the scroll direction in step S31 is an oblique direction, the fixed area determination processing unit 15 performs an oblique direction with respect to the image of the non-fixed area NF including the second contact point in response to the drag of the second finger. And the predetermined rectangular area including the first contact point is determined as the fixed area F (S32). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S32).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S32). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = oblique direction” in the information storage medium 25 (S33).

  When it is determined in step S31 that the scroll direction is only the horizontal direction, the fixed area determination processing unit 15 is horizontal with respect to the image of the non-fixed area NF including the second contact point in response to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S34). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S34).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S34). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S35).

  When it is determined that the scroll direction in step S31 is only the vertical direction, the fixed area determination processing unit 15 is vertical to the image of the NF outside the fixed area including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S36). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S36).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S36). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S37).

  After the scroll flag is written in the information storage medium 25 in step S33, step S35, or step S37, the operation content determination processing unit 12 writes information indicating that “initial flag = 0” in the information storage medium 25. Then, the information of the initial flag is updated (S38).

  After the initial flag information is updated in step S38, in FIG. 11, the inertial scroll determination processing unit 20 determines whether the scrolled image outside the fixed area NF displayed on the display screen of the display unit 5 is inertial scrolled. It is determined whether or not (S39).

  When it is determined that the scrolled image of the non-fixed area NF displayed on the display screen of the display unit 5 is not inertial scrolled, the non-fixed area display processing unit 17 stores the scroll stored in the information storage medium 25. According to the flag (S40), a scrolled image is generated by scrolling the image displayed in the non-fixed area NF immediately before the second finger is dragged in the scroll direction determined by the fixed area determination processing unit 15. Are displayed (S41 to S43).

  Specifically, when the scroll flag is in an oblique direction, the fixed area outside display processing unit 17 scrolls the image displayed in the fixed area outside NF immediately before dragging the second finger in the oblique direction. A generated image is generated, and the generated scrolled image is output to the display image generating unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S41).

  In addition, when the scroll flag is in the horizontal direction, the non-fixed area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the non-fixed area NF immediately before dragging the second finger in the horizontal direction. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S42).

  In addition, when the scroll flag is in the vertical direction, the outside fixed area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the outside fixed area NF immediately before the second finger is dragged in the vertical direction. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S43).

  When it is determined that the scrolled image of the non-fixed area NF displayed on the display screen of the display unit 5 is inertial scrolling, the non-fixed area display processing unit 17 scrolls the information stored in the information storage medium 25. In accordance with the flag (S44), the image displayed on the NF outside the fixed area immediately before the second finger is dragged is inertial scrolled at the inertial scroll speed S1 in the scroll direction determined by the fixed area determination processing unit 15. A scrolled image is generated and displayed (S45 to S47).

  Specifically, when the scroll flag is in the oblique direction, the outside fixed area display processing unit 17 performs the inertial scroll speed S1 in the oblique direction on the image displayed in the non-fixed area NF immediately before the second finger is dragged. Then, a scrolled image obtained by inertial scrolling is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S45).

  In addition, when the scroll flag is in the horizontal direction, the out-of-fixed-region display processing unit 17 performs the inertial scrolling of the image displayed in the out-of-fixed region NF immediately before dragging the second finger at the inertial scroll speed S1 in the horizontal direction. The generated scrolled image is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S46).

  Further, when the scroll flag is in the vertical direction, the out-of-fixed-region display processing unit 17 performs the inertial scroll speed S1 on the image displayed in the out-of-fixed region NF just before the second finger is dragged in the vertical direction. The generated scrolled image is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S47).

  After the scrolled image is displayed, when the first finger touches the fixed area F and the second finger touches the non-fixed area NF but does not drag, the inertial scroll determination processing unit 20 It is determined whether or not the scrolled image displayed on the non-fixed area NF on the display screen of the display unit 5 is inertial scrolling (S48). When it is determined that the scrolled image displayed outside the fixed area NF of the display screen of the display unit 5 is inertia scrolling, the scroll stop processing unit 21 touches both the first finger and the second finger. The execution of the inertial scroll is stopped according to the state being performed (S49). At this time, the inertial scroll determination processing unit 20 writes the inertial scroll flag stored in the information storage medium 25 as “0”, thereby updating the information related to the inertial scroll flag (S50).

  When the scrolled image displayed on the NF outside the fixed area of the display screen of the display unit 5 is not inertial scrolling and the user's finger is touching the display unit 5, the scroll stop processing unit 21 It is determined whether the touching finger is the first finger or the second finger (S51).

  When it is determined in step S51 that the first finger is touching the display unit 5, the scroll stop processing unit 21 cancels the display division state between the fixed image and the scrolled image, and the first finger is moved. The outside fixed area display processing unit 17 is instructed to display the touched fixed image on the entire display unit 5 (S52). The non-fixed area display processing unit 17 generates a fixed image displayed in the fixed area F as a scrolled image based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5. Note that the coordinates when the first finger is touching the display unit 5 are preferably the same as the coordinates of the first contact point (X1, Y1) acquired in step S22, but in the vicinity of the coordinates. But it ’s okay.

  When it is determined in step S51 that the second finger is touching the display unit 5, the scroll stop processing unit 21 cancels the display division state between the fixed image and the scrolled image, and the second finger is moved. The outside fixed area display processing unit 17 is instructed to display the touched scrolled image on the entire display unit 5 (S53). The out-of-fixed-area display processing unit 17 generates a scrolled image displayed on the out-of-fixed-area NF based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5. Note that the coordinates when the second finger is touching the display unit 5 are preferably the same as the coordinates of the second contact point (X2, Y2) acquired in step S29, but in the vicinity of the coordinates. But it ’s okay.

  The scroll stop processing unit 21 determines that the user's finger does not touch the display unit 5 when the scrolled image displayed on the NF outside the fixed area of the display screen of the display unit 5 is not inertial scrolling. If it is done, a fixed image or a scrolled image is displayed on the display screen of the display unit 5. In this case, it is preferable that whether the fixed image or the scrolled image is displayed on the display unit 5 is defined in advance in the operation of the scroll stop processing unit 21. Thereafter, the operations in steps S21 to S53 described above are repeated.

  As described above, the mobile phone 10a according to the second embodiment displays a predetermined rectangular area including the first contact point touched by the first finger on the image displayed on the display screen of the display unit 5. The fixed area F of the entire image is determined, and the display area excluding the fixed area F of the entire image including the second contact point touched by the second finger is determined to be NF outside the fixed area.

  In addition, the mobile phone 10a generates a fixed image of a predetermined rectangular area determined as the fixed area F, and displays the image displayed in the display area determined as the non-fixed area NF on the display screen of the display unit 5. A scrolled image is generated that is scrolled in the scroll direction determined according to the coordinates of the second contact point and the drag direction and distance of the second finger. The mobile phone 10 a displays a composite image obtained by combining the generated fixed image and the scrolled image on the display screen of the display unit 5.

  Furthermore, when the mobile phone 10a touches the second finger when the scrolled image displayed on the NF outside the fixed area of the display screen of the display unit 5 is performing normal scrolling or inertial scrolling, In addition, the execution of the normal scroll or the inertial scroll is stopped, and the fixed image or the normal scroll or the inertial scroll is performed according to the first finger or the second finger touching the display unit 5 thereafter. The scrolled image is displayed on the entire display screen of the display unit 5.

  Therefore, according to the mobile phone 10a of the second embodiment, a part of the content displayed on the display screen is fixed and a fixed part of the display screen is fixed according to an intuitive and simple operation. You can scroll other areas that are not covered. For this reason, the user can intuitively and simply perform finger scrolling and dragging on the scroll direction of the image displayed on the display screen of the display unit 5 in the fixed portion or the display divided portion, or the image displayed outside the fixed region NF. The selection of the fixed area F and the scrolling of the NF outside the fixed area can be easily realized by only the operation of at least two fingers.

  Furthermore, according to the mobile phone 10a, the normal scrolling or inertial scrolling operation can be started or stopped simply and with a simple operation of two fingers. Therefore, when the normal scrolling or inertial scrolling operation is stopped, the initial fixed image is displayed or scrolled by an intuitive and simple operation of touching the first finger or the second finger. A scrolled image can be displayed.

7). Configuration of Mobile Phone 10b of Third Embodiment FIG. 13 is a block diagram showing an internal configuration of a mobile phone 10b that is an example of the electronic apparatus of the invention. As illustrated in FIG. 13, the mobile phone 10 b includes a display processing unit 13 b that further includes a fixed area movement / copy processing unit 22 in the display processing unit 13 a of the mobile phone 10 a according to the second embodiment. Since the configuration other than the fixed area movement / copy processing unit 22 is the same as that of the mobile phone 10a of the second embodiment, the description regarding the same contents is omitted.

  The fixed area movement / copy processing unit 22 touches the fixed image displayed on the display screen of the display unit 5 with the first finger and the scrolled image displayed on the display screen of the display unit 5 with the second finger. In a state where the image is touched, it is determined whether or not a touch input operation in which the first finger is dragged by a predetermined distance in a predetermined direction is performed. When it is determined that the touch input operation has been performed, the fixed area movement / copy processing unit 22 determines whether to move or copy the fixed image so as to be displayed interruptively immediately before the scrolled image. A dialog window for allowing the user to select is displayed on the display unit 5.

  The fixed area movement / copy processing unit 22 moves or copies the fixed image so as to be displayed in an interrupted manner immediately before the scrolled image according to the user's selection, and is stored in the information storage medium 25. Update the order of the image data.

8). Operation Example of Fixed Area Movement / Copy Processing Unit 22 Next, an operation example of the fixed area movement / copy processing unit 22 will be described with reference to FIG. FIG. 14 is an explanatory diagram illustrating an example of a state before and after the display division between the fixed area F and the non-fixed area NF in the third embodiment. 14, the image browsing application is operating in the state C, the state D, the state E, and the state M illustrated in FIG. Each image shown in FIG. 14 is displayed on the display screen of the display unit 5 of the mobile phone 10b. Note that the state C and the state D in FIG. 14 are the same as the state C and the state D illustrated in FIG. 3, and thus the description of the state C and the state D is omitted. 14, the information storage medium 25 of the mobile phone 10 includes a flower bed image (image ID = 1), a building image (image ID = 2), and an animal image (image ID = 3). ), Window image (image ID = 4), night view image (image ID = 5), and stationery image (image ID = 6).

  For example, in the state E of FIG. 14, the display unit 5 displays a flower bed image that is a fixed image within a range AR of a predetermined rectangular area indicating the fixed area F touched by the first finger, and the second finger A night scene image, which is a scrolled image obtained by normal scrolling or inertial scrolling, is displayed on a non-fixed area NF that is a display area that includes the second contact point touched by and that excludes the fixed area F from the entire display screen.

  In this state E, when the first finger drags a predetermined distance in a predetermined direction, the fixed area movement / copy processing unit 22 interrupts the fixed image displayed in the fixed area F immediately before the scrolled image. A dialog window is displayed on the display unit 5 for allowing the user to select whether to move or copy so as to be displayed.

  For example, when the user selects movement for this dialog window, the fixed area movement / copy processing unit 22 is positioned immediately before the night scene image that is the scrolled image, that is, at the position of the image ID immediately before the night scene image. By moving the flower bed image which is a fixed image, the order of the image IDs of the images related to the movement among the image IDs of the image data stored in the information storage medium 25 is updated. Specifically, in the state M of FIG. 14, a building image (image ID = 1), an animal image (image ID = 2), a window image (image ID = 3), a flower bed image (image ID = 4), a night view image ( Image ID = 5) and stationery image (image ID = 6) are updated in this order. At this time, the fixed area movement / copy processing unit 22 outputs to the fixed area determination processing unit 15 that the flower bed image, which is a fixed image, has been moved immediately before the night scene image, which is a scrolled image.

  The fixed region determination processing unit 15 instructs the fixed region display processing unit 16 and the non-fixed region display processing unit 17 to display the moved flower bed image on the entire display unit 5. In this case, the fixed area display processing unit 16 does not generate a fixed image, and the non-fixed area display processing unit 17 can display the moved flower bed image on the display area outside the fixed area NF (the entire display screen of the display unit 5). A flower bed image having a proper size is generated and output to the display image generation unit 18. The display image generation unit 18 outputs the output flower bed image to the display control unit 19. The display control unit 19 displays the output flower bed image on the entire display screen of the display unit 5.

  For example, when the user selects copy for this dialog window, the fixed area movement / copy processing unit 22 immediately before the night scene image that is the scrolled image, that is, at the position of the image ID immediately before the night scene image. By copying the flower bed image that is a fixed image, the image ID of the image after the copied flower bed image is increased by one in the order of the image IDs of the image data stored in the information storage medium 25. To do. Specifically, in the state M of FIG. 14, a flower bed image (image ID = 1), a building image (image ID = 2), an animal image (image ID = 3), a window image (image ID = 4), a flower bed image ( Image ID = 5), night view image (image ID = 6), and stationery image (image ID = 7) are updated in this order. At this time, the fixed area movement / copy processing unit 22 outputs to the fixed area determination processing unit 15 that the flower bed image that is a fixed image is copied immediately before the night scene image that is a scrolled image.

  The fixed region determination processing unit 15 instructs the fixed region display processing unit 16 and the non-fixed region display processing unit 17 to display the copied flower bed image on the entire display unit 5. In this case, the fixed area display processing unit 16 does not generate a fixed image, and the non-fixed area display processing unit 17 can display the moved flower bed image on the display area outside the fixed area NF (the entire display screen of the display unit 5). A flower bed image having a proper size is generated and output to the display image generation unit 18. The display image generation unit 18 outputs the output flower bed image to the display control unit 19. The display control unit 19 displays the output flower bed image on the entire display screen of the display unit 5.

9. Description of Operation of Mobile Phone 10b of Third Embodiment FIGS. 15 to 18 are flowcharts showing the operation of the mobile phone 10b of the third embodiment. Prior to the following description, it is assumed that an arbitrary image is displayed in advance on the display screen of the display unit 5 of the mobile phone 10b.

  In FIG. 15, the operation content determination processing unit 12 determines whether or not a touch input operation is performed in which the first finger of the user touches the display screen of the display unit 5 (S61). When it is determined that the touch input operation is performed in step S61, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S62).

  The operation content determination processing unit 12 determines whether or not a touch input operation is performed in which the second finger touches the display screen of the display unit 5 following the touch of the first finger determined in step S61. (S63). When it is determined that the touch input operation has been performed in step S63, the operation content determination processing unit 12 touches the display unit 5 with the second finger, and then the first finger starts from the first contact point on the display unit 5. It is determined whether or not a touch input operation of dragging a predetermined distance in a predetermined direction has been performed (S64).

  If it is determined that the touch input operation is performed in step S64, the fixed area movement / copy processing unit 22 scrolls the fixed image displayed in the fixed area F in the display area of the non-fixed area NF. A dialog window is displayed on the display unit 5 for allowing the user to select whether to move or copy so as to be displayed in an interrupted manner immediately before the selected image (S65).

  The fixed area movement / copy processing unit 22 moves or copies the fixed image so as to be displayed in an interrupted manner immediately before the scrolled image in response to the touch input operation selected by the user (S66) (S67). , S68).

  Specifically, when the user selects the movement (S66), the fixed area movement / copy processing unit 22 is displayed in an interrupted manner immediately before the scrolled image displayed in the current non-fixed area NF. Next, the fixed image displayed in the fixed area F is moved (S67). At this time, the fixed area movement / copy processing unit 22 moves the fixed image so that the fixed image is displayed in an interrupted manner immediately before the scrolled image, so that the image data stored in the information storage medium 25 is stored. Of the image IDs, the order of the image IDs of the images related to the movement is updated. At this time, the fixed area movement / copy processing unit 22 outputs to the fixed area determination processing unit 15 that the fixed image has been moved immediately before the scrolled image.

  The fixed area determination processing unit 15 instructs the fixed area display processing unit 16 and the non-fixed area display processing unit 17 to display the moved fixed image on the entire display unit 5. In this case, the fixed area display processing unit 16 does not generate a fixed image, and the non-fixed area display processing unit 17 generates an image in which the moved fixed image is sized to be displayed on the entire display unit 5 to display the display image. The data is output to the generation unit 18. As a result, the display image generation unit 18 outputs the image output by the out-of-fixed-region display processing unit 17 to the display control unit 19, and the display control unit 19 displays the output image on the entire display screen of the display unit 5. (S69).

  When the user selects copy (S66), the fixed area movement / copy processing unit 22 causes the fixed area F to be displayed in an interrupted manner immediately before the scrolled image displayed in the current non-fixed area NF. The fixed image displayed in is copied (S68). At this time, the fixed area movement / copy processing unit 22 copies the fixed image so that the fixed image is displayed in an interrupted manner immediately before the scrolled image, so that the image data stored in the information storage medium 25 is stored. The image IDs of the images after the copied flower bed image in the order of the image IDs are updated so as to be increased by one. Further, the fixed area movement / copy processing unit 22 outputs to the fixed area determination processing unit 15 that the fixed image has been copied immediately before the scrolled image.

  The fixed area determination processing unit 15 instructs the fixed area display processing unit 16 and the non-fixed area display processing unit 17 to display the copied fixed image on the entire display unit 5. In this case, the fixed area display processing unit 16 does not generate a fixed image, and the non-fixed area display processing unit 17 generates an image in which the copied fixed image has a size that can be displayed on the entire display unit 5 to display the display image. The data is output to the generation unit 18. As a result, the display image generation unit 18 outputs the image output by the out-of-fixed-region display processing unit 17 to the display control unit 19, and the display control unit 19 displays the output image on the entire display screen of the display unit 5. (S69).

  After the fixed image moved or copied in step S69 is displayed on the entire display screen of the display unit 5, the operation content determination processing unit 12 performs a touch input operation in which the user's first finger touches the display unit 5. It is determined whether it has been performed (S61). When it is determined that the touch input operation is performed in step S61, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S62).

  The operation content determination processing unit 12 determines whether or not a touch input operation is performed in which the second finger touches the display unit 5 following the touch of the first finger determined in step S61 (S63). . When it is determined that the touch input operation has been performed in step S63, the operation content determination processing unit 12 touches the display unit 5 with the second finger, and then the first finger starts from the first contact point on the display unit 5. It is determined whether or not a touch input operation of dragging a predetermined distance in a predetermined direction has been performed (S64).

  When it is determined that the touch input operation is not performed in step S64, the operation content determination processing unit 12 performs a touch input operation that the second finger touches the display unit 5 and then drags a predetermined distance in a predetermined direction. It is determined whether it has been performed (S70).

  When it is determined that the touch input operation is performed in step S70, the inertial scroll determination processing unit 20 determines whether the touch input operation is an operation for instructing execution of the inertial scroll (S71).

  If it is determined in step S71 that the touch input operation is an operation for instructing execution of inertial scroll, the inertial scroll determination processing unit 20 sends information indicating that “inertial scroll flag = 1” to the information storage medium 25. Write (S72). At this time, the inertial scroll determination processing unit 20 calculates the coordinate change amount (ΔX2, ΔY2) and the drag time (ΔT2) when the second finger drags a predetermined distance from the second contact point, and the operation content determination processing unit 12. (S73). Further, as described above, the inertial scroll determination processing unit 20 calculates the inertial scroll speed S1 based on the acquired coordinate change amounts (ΔX2, ΔY2) and the drag time (ΔT2) (S74).

  When it is determined that the touch input operation in step S71 is not an operation for instructing execution of inertial scrolling, the operation content determination processing unit 12 determines the dragged second contact point based on the touch input operation in step S70. Information on the coordinate change amounts (ΔX2, ΔY2) is acquired, and the information on the coordinate change amounts is written in the information storage medium 25 (S75).

  Note that the operation content determination processing unit 12 has the coordinates before dragging (X2s, Y2s) and the coordinates after dragging of the second contact point (X2e) when the second finger touches the display screen of the display unit 5. , Y2e), the coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired by acquiring the information of the coordinate change amount (ΔX2, ΔY2) of the second contact point.

  The operation content determination processing unit 12 determines whether or not the drag of the second finger is the first drag, that is, whether or not the initial flag is “1” (S76). When it is determined that the drag of the second finger is the first drag, the fixed area determination processing unit 15 coordinates the coordinates of the second contact point on the display screen by the second finger and the drag from the second contact point. Depending on the direction and distance, the scroll direction with respect to the image displayed on the non-fixed area NF including the second contact point and excluding the predetermined fixed area F including the first contact point from the entire display screen of the display unit 5 Is determined (S77).

  Note that the fixed area determination processing unit 15 is based on the coordinates of the second contact point on the display screen of the display unit 5 and the coordinate change amount (ΔX2, ΔY2) of the second contact point acquired in step S29. It is preferable to determine the scroll direction of the image of the non-fixed area NF including the second contact point. For example, when ΔX2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the vertical direction. When ΔY2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the horizontal direction. In addition, when ΔX2 and ΔY2 of the coordinate change amounts (ΔX2, ΔY2) of the second contact point are not substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is an oblique direction.

  When it is determined that the scroll direction in step S77 is an oblique direction, the fixed area determination processing unit 15 performs an oblique direction with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. And the predetermined rectangular area including the first contact point is determined as the fixed area F (S78). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point of the second finger and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S78).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S78). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = oblique direction” in the information storage medium 25 (S79).

  When it is determined in step S77 that the scroll direction is only the horizontal direction, the fixed area determination processing unit 15 is horizontal with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S80). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point of the second finger and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S80).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S80). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S81).

  When it is determined in step S77 that the scroll direction is only the vertical direction, the fixed area determination processing unit 15 is vertical to the image of the NF outside the fixed area including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S82). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point of the second finger and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S82).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S82). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S82).

  After the scroll flag is written in the information storage medium 25 in step S79, step S81, or step S83, the operation content determination processing unit 12 writes “initial flag = 0” in the information storage medium 25, thereby Information on the initial flag is updated (S84).

  After the initial flag information is updated in step S84, in FIG. 17, the inertial scroll determination processing unit 20 determines whether the scrolled image outside the fixed area NF displayed on the display screen of the display unit 5 is inertial scrolled. It is determined whether or not (S85).

  When it is determined that the scrolled image of the non-fixed area NF displayed on the display screen of the display unit 5 is not inertial scrolled, the non-fixed area display processing unit 17 stores the scroll stored in the information storage medium 25. According to the flag (S86), a scrolled image is generated by scrolling the image displayed in the non-fixed area NF immediately before the second finger dragging in the scroll direction determined by the fixed area determination processing unit 15. Are displayed (S87 to S89).

  Specifically, when the scroll flag is in an oblique direction, the fixed area outside display processing unit 17 scrolls the image displayed in the fixed area outside NF immediately before dragging the second finger in the oblique direction. A generated image is generated, and the generated scrolled image is output to the display image generating unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S87).

  Furthermore, when the scroll flag is in the horizontal direction, the non-fixed area display processing unit 17 scrolls the image displayed in the non-fixed area NF immediately before dragging the second finger in the horizontal direction. An image is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S88).

  Furthermore, when the scroll flag is in the vertical direction, the out-of-fixed-area display processing unit 17 scrolls the image displayed in the out-of-fixed area NF immediately before dragging the second finger in the vertical direction. An image is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S89).

  When it is determined that the scrolled image of the non-fixed area NF displayed on the display screen of the display unit 5 is inertial scrolling, the non-fixed area display processing unit 17 scrolls the information stored in the information storage medium 25. In accordance with the flag (S90), the image displayed on the NF outside the fixed area immediately before the second finger is dragged is inertial scrolled at the inertial scroll speed S1 in the scroll direction determined by the fixed area determination processing unit 15. A scrolled image is generated and displayed (S91 to S93).

  Specifically, when the scroll flag is in the oblique direction, the outside fixed area display processing unit 17 performs the inertial scroll speed S1 in the oblique direction on the image displayed in the non-fixed area NF immediately before the second finger is dragged. Then, a scrolled image obtained by inertial scrolling is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S91).

  In addition, when the scroll flag is in the horizontal direction, the out-of-fixed-region display processing unit 17 performs the inertial scrolling of the image displayed in the out-of-fixed region NF immediately before dragging the second finger at the inertial scroll speed S1 in the horizontal direction. The generated scrolled image is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S92).

  Further, when the scroll flag is in the vertical direction, the out-of-fixed-region display processing unit 17 performs the inertial scroll speed S1 on the image displayed in the out-of-fixed region NF just before the second finger is dragged in the vertical direction. The generated scrolled image is generated, and the generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S93).

  After the scrolled image is displayed, when the first finger touches the fixed area F and the second finger touches the non-fixed area NF but does not drag, the inertial scroll determination processing unit 20 It is determined whether or not the scrolled image displayed on the NF outside the fixed area on the display screen of the display unit 5 is inertial scrolling (S94). When it is determined that the scrolled image displayed outside the fixed area NF of the display screen of the display unit 5 is inertia scrolling, the scroll stop processing unit 21 touches both the first finger and the second finger. The execution of the inertial scroll is stopped according to the state being performed (S95). At this time, the inertial scroll determination processing unit 20 writes the inertial scroll flag stored in the information storage medium 25 as “0”, thereby updating the information related to the inertial scroll flag (S96).

  When the scrolled image displayed on the NF outside the fixed area of the display screen of the display unit 5 is not inertial scrolling and the user's finger is touching the display unit 5, the scroll stop processing unit 21 It is determined whether the touching finger is the first finger or the second finger (S97).

  When it is determined in step S97 that the first finger is touching the display unit 5, the scroll stop processing unit 21 cancels the display division state between the fixed image and the scrolled image, and the first finger is moved. The outside fixed area display processing unit 17 is instructed to display the touched fixed image on the entire display unit 5 (S98). The non-fixed area display processing unit 17 generates a fixed image displayed in the fixed area F as a scrolled image based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5. Note that the coordinates when the first finger is touching the display unit 5 may be the same as or close to the coordinates of the first contact point (X1, Y1) acquired in step S62.

  When it is determined in step S97 that the second finger is touching the display unit 5, the scroll stop processing unit 21 cancels the display division state between the fixed image and the scrolled image, and the second finger moves. The outside fixed area display processing unit 17 is instructed to display the touched scrolled image on the entire display unit 5 (S99). The out-of-fixed-area display processing unit 17 generates a scrolled image displayed on the out-of-fixed-area NF based on the instruction output by the scroll stop processing unit 21. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

  The scroll stop processing unit 21 determines that the user's finger does not touch the display unit 5 when the scrolled image displayed on the NF outside the fixed area of the display screen of the display unit 5 is not inertial scrolling. If it is done, a fixed image or a scrolled image is displayed on the display screen of the display unit 5. In this case, it is preferable that whether the fixed image or the scrolled image is displayed on the display unit 5 is defined in advance in the operation of the scroll stop processing unit 21. Thereafter, the operations in steps S61 to S99 described above are repeated.

  As described above, the cellular phone 10b according to the third embodiment displays a predetermined rectangular area including the first contact point touched by the first finger on the image displayed on the display screen of the display unit 5. The fixed area F of the entire image is determined, and the display area excluding the fixed area F of the entire image including the second contact point touched by the second finger is determined to be NF outside the fixed area.

  Furthermore, the mobile phone 10b generates a fixed image of a predetermined rectangular area determined as the fixed area F, and displays the image displayed in the display area determined as the non-fixed area NF on the display screen of the display unit 5. A scrolled image is generated that is scrolled in the scroll direction determined according to the coordinates of the second contact point and the drag direction and distance of the second finger. The mobile phone 10 b displays a composite image obtained by combining the generated fixed image and the scrolled image on the display screen of the display unit 5.

  Furthermore, when the mobile phone 10b touches the second finger when the scrolled image displayed on the NF outside the fixed area of the display screen of the display unit 5 is performing normal scrolling or inertial scrolling, In addition, the execution of the normal scroll or the inertial scroll is stopped, and the fixed image or the normal scroll or the inertial scroll is performed according to the first finger or the second finger touching the display unit 5 thereafter. The scrolled image is displayed on the entire display unit 5.

  Furthermore, when the first finger and the second finger are touching the display unit 5 and the first finger is dragged in a predetermined direction by a predetermined distance, the mobile phone 10b is connected to the first finger. A display unit for displaying a dialog window for moving or copying the fixed image of the touched fixed area F so that the fixed image is displayed interruptively just before the scrolled image of the non-fixed area NF touched by the second finger. 5 is displayed. The mobile phone 10b updates the order of the image data by moving or copying according to the user's selection for moving or copying. The mobile phone 10 b displays the fixed image that has been moved or copied so as to be displayed in an interrupted manner immediately before the scrolled image on the entire display screen of the display unit 5.

  Therefore, according to the mobile phone 10b of the third embodiment, a part of the content displayed on the display screen is fixed and a fixed portion of the display screen is fixed according to an intuitive and simple operation. You can scroll other areas that are not covered. For this reason, the user can intuitively and simply perform finger scrolling and dragging on the scroll direction of the image displayed on the display screen of the display unit 5 in the fixed portion or the display divided portion, or the image displayed outside the fixed region NF. The selection of the fixed area F and the scrolling of the NF outside the fixed area can be easily realized by only the operation of at least two fingers.

  Furthermore, according to the mobile phone 10b, it is possible to intuitively and easily start or stop a normal scrolling or inertial scrolling operation only by operating two fingers. Therefore, when the normal scrolling or inertial scrolling operation is stopped, the initial fixed image is displayed or scrolled by an intuitive and simple operation of touching the first finger or the second finger. A scrolled image can be displayed.

  Furthermore, according to the mobile phone 10b, the intuitive image of dragging the first finger in a predetermined direction for a predetermined distance allows the fixed image touched by the first finger to be interrupted immediately before the scrolled image. The fixed image can be easily moved or copied so as to be displayed on the screen, and the fixed image that has been moved or copied can be displayed on the entire display screen of the display unit 5.

  In the state N of FIG. 20, the fixed image is displayed on the display unit 5 within the range AR of a predetermined rectangular area indicating the fixed area F touched by the first finger, and the second contact touched by the second finger. A scrolled image is displayed that is scrolled to a non-fixed area NF that is a display area that includes a point and excludes the fixed area F from the entire display screen.

  In this state N, the scroll wheel processing unit 23 determines whether or not a touch input operation is performed in which the second finger is double-clicked at a certain position within the fixed area NF. When it is determined that the touch input operation has been performed, the scroll wheel processing unit 23, as shown in the state O, has a diameter of a predetermined length centered on the second contact point touched by the second finger. Are displayed on the concentric scroll wheel SW. The length of each diameter of the scroll wheel SW is preferably defined in advance by the operation of the scroll wheel processing unit 23 or the information storage medium 25.

  In the state O, the scroll wheel processing unit 23 rotates the second finger clockwise (or counterclockwise) from the center of the scroll wheel SW toward the periphery as shown in the state P or the state Q. It is determined whether or not a touch input operation is performed. When it is determined that the touch input operation has been performed, the scroll wheel processing unit 23 converts the scrolled image displayed in the display area outside the fixed area NF into the horizontal right direction or the vertical down direction (or the horizontal left direction or The outside fixed area display processing unit 17 is instructed to generate a scrolled image that is scrolled vertically upward).

  The non-fixed area display processing unit 17 displays the scrolled image displayed in the non-fixed area NF display area based on an instruction from the scroll wheel processing unit 23 in the horizontal right direction or the vertical down direction (or horizontal left). A scrolled image that is scrolled in a direction or vertically upward direction). The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

  Further, in the state O, the scroll wheel processing unit 23 causes the second finger to move at a small rotation angle or a large rotation angle from the center part to the peripheral part of the scroll wheel SW as shown in the state R or the state S. Then, it is determined whether or not a touch input operation that is rotated clockwise (or counterclockwise) is performed. When it is determined that the touch input operation has been performed, the scroll wheel processing unit 23 moves the scrolled image displayed in the display area outside the fixed area NF in the horizontal right direction or at the scroll speed S2 according to the rotation angle. The outside fixed area display processing unit 17 is instructed to generate a scrolled image that is scrolled vertically downward (or horizontally left or vertically upward).

  Note that the non-fixed area display processing unit 17 horizontally scrolls the scrolled image displayed in the non-fixed area NF display area at the scroll speed S2 corresponding to the rotation angle based on an instruction from the scroll wheel processing unit 23. A scrolled image that is scrolled in the direction or vertically downward (or horizontally left or vertically upward) is generated. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

  If it is determined that a touch input operation is performed in which the second finger rotates clockwise from the center of the scroll wheel SW toward the periphery, the scroll wheel processing unit 23 displays the display on the display unit 5. Depending on the coordinates of the second contact point of the second finger with respect to the screen, the coordinate change amount of the second contact point after the scroll wheel SW is displayed, and the inclination determined by the coordinate change amount, the scroll image is scrolled horizontally. One of right direction and vertically downward direction is determined. Similarly, when it is determined that a touch input operation has been performed in which the second finger rotates counterclockwise from the center of the scroll wheel SW toward the periphery, the scroll wheel processing unit 23 displays the display unit. Scrolling the scrolled image according to the coordinates of the second contact point of the second finger on the display screen 5, the coordinate change amount of the second contact point after the scroll wheel SW is displayed, and the inclination determined by the coordinate change amount One of the horizontal left direction and the vertical upward direction is determined as the direction.

  Furthermore, the relationship between the rotation angle of the second finger rotated from the center portion of the scroll wheel SW toward the peripheral portion and the scroll speed corresponding to the rotation angle depends on the operation of the scroll wheel processing unit 23 or the information storage medium 25. It is preferable that it is prescribed in advance.

  Further, the scroll wheel processing unit 23 determines whether or not a touch input operation is performed in which the second finger is dragged from the peripheral part of the scroll wheel SW to the central part as shown in the state T. When it is determined that the touch input operation has been performed, the scroll wheel processing unit 23 stops executing scrolling on the scrolled image displayed in the display area outside the fixed area NF. The scroll wheel processing unit 23 instructs the out-of-fixed-region display processing unit 17 to display the scrolled image at the moment when the execution of the scroll performed on the scrolled image is stopped on the out-of-fixed region NF. .

  The non-fixed area display processing unit 17 generates a scrolled image displayed in the non-fixed area NF display area based on an instruction from the scroll wheel processing unit 23. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

  In the state U of FIG. 21, the fixed image is displayed on the display unit 5 within the range AR of a predetermined rectangular area indicating the fixed area F touched by the first finger, and the second contact touched by the second finger. A scrolled image is displayed that is scrolled to a non-fixed area NF that is a display area that includes a point and excludes the fixed area F from the entire display screen.

  In this state U, the scroll wheel processing unit 23, as shown in the information V or the state W, drags the second finger in an oblique direction from the center to the periphery of the scroll wheel SW, and the state X or the state Y As shown in FIG. 5, it is determined whether or not a touch input operation has been performed on the basis of the position after the dragging as a starting point and the rotation is clockwise (or counterclockwise) with a small rotation angle or a large rotation angle. When it is determined that the touch input operation has been performed, the scroll wheel processing unit 23 drags the scrolled image displayed in the display area outside the fixed area NF at the scroll speed S2 corresponding to the rotation angle. The outside fixed area display processing unit 17 is instructed to generate a scrolled image that is scrolled in an oblique direction.

  Note that the non-fixed-area display processing unit 17 obliquely displays the scrolled image displayed in the non-fixed-area NF display area based on the instruction from the scroll wheel processing unit 23 at the scroll speed S2 corresponding to the rotation angle. A scrolled image is generated by scrolling to. The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18. The display image generation unit 18 outputs the output scrolled image to the display control unit 19. The display control unit 19 displays the output scrolled image on the display screen of the display unit 5.

12 Description of Operation of Mobile Phone 10c of Fourth Embodiment FIGS. 22 to 25 are flowcharts showing the operation of the mobile phone 10c of the fourth embodiment. In the following description, it is assumed that an arbitrary image is displayed in advance on the display screen of the display unit 5 of the mobile phone 10c.

  In FIG. 22, the operation content determination processing unit 12 determines whether or not a touch input operation is performed in which the first finger of the user touches the display unit 5 (S101). When it is determined that the touch input operation is performed in step S101, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating that “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S102).

  The scroll wheel processing unit 23 writes information indicating that “wheel flag (Wheel_Flg) = 0” in the information storage medium 25 (S103). The wheel flag “0” indicates a state in which the scroll wheel SW is not displayed on the display screen of the display unit 5. The wheel flag “1” indicates a state in which the scroll wheel SW is displayed on the display screen of the display unit 5.

  After the information indicating that the wheel flag is “0” is written in the information storage medium 25, the operation content determination processing unit 12 determines that the second finger is touched following the first finger touch determined in step S101. It is determined whether or not a touch input operation of touching the display screen of the display unit 5 has been performed (S104). When it is determined that the touch input operation has been performed in step S104, the operation content determination processing unit 12 touches the display screen of the display unit 5 with the second finger and then drags the predetermined distance in a predetermined direction. Whether or not has been performed is determined (S105).

  When it is determined that the touch input operation is performed in step S105, the scroll wheel processing unit 23 determines whether or not the touch input operation is an operation on the scroll wheel SW (S106). As will be described later, when the scroll wheel processing unit 23 displays the scroll wheel SW on the display screen of the display unit 5, the scroll wheel processing unit 23 stores coordinate information indicating the display range of the displayed scroll wheel SW in the information storage medium 25. To do. The scroll wheel processing unit 23 acquires the target coordinates of the touch input operation in step S105 from the operation content determination processing unit 12, and compares the acquired target coordinates with coordinate information indicating the display range of the scroll wheel SW. Then, it is determined whether or not the operation is on the scroll wheel SW.

  When it is determined in step S106 that the touch input operation is not an operation on the scroll wheel SW, the operation content determination processing unit 12 determines the coordinate change amount (the second contact point dragged based on the touch input operation) Information on [Delta] X2, [Delta] Y2) is acquired, and information on the coordinate change amount is written in the information storage medium 25 (S107). Note that the operation content determination processing unit 12 has the coordinates before dragging (X2s, Y2s) and the coordinates after dragging of the second contact point (X2e) when the second finger touches the display screen of the display unit 5. , Y2e), the coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired by acquiring the information of the coordinate change amount (ΔX2, ΔY2) of the second contact point.

  When it is determined that the touch input operation in step S106 is an operation on the scroll wheel SW, the scroll wheel processing unit 23 determines the first drag start coordinates (X2s, Y2s) of the second contact point and step S105. A coordinate change angle amount (Δ∠α) due to a change due to a change from the current drag end coordinates (X2e, Y2e) after dragging by a touch input operation is acquired, and coordinate information and coordinate change angle amount before and after the drag are stored as information. Writing to the medium 25 (S108).

  In step S108, the scroll wheel processing unit 23 acquires the operation content using the scroll wheel SW, which is the touch input operation in step S106, from the operation content determination processing unit 12. The content of the touch input operation using the scroll wheel SW acquired from the operation content determination processing unit 12 corresponds to one of the following.

  For example, the second finger drags in an oblique direction from the center of the scroll wheel SW toward the periphery, and turns clockwise (or counterclockwise with a small rotation angle or a large rotation angle from the position after the dragging as a starting point. “Touch input operation A” corresponding to rotation).

  Further, “touch input operation B” in which the second finger is rotated clockwise by a small rotation angle or a large rotation angle from the center to the periphery of the scroll wheel SW is applicable.

  Further, “touch input operation C” in which the second finger is rotated counterclockwise at a small rotation angle or a large rotation angle from the center portion to the peripheral portion of the scroll wheel SW is applicable.

  The scroll wheel processing unit 23 performs any one of the touch input operation A, the touch input operation B, and the touch input operation C by a scroll direction determination process (S110 to S116) by the first drag operation of the second finger described later. The content of the operation using the scroll wheel SW that is the touch input operation is acquired from the operation content determination processing unit 12, and the scroll information is written in the information storage medium 25.

  Specifically, the scroll wheel processing unit 23 performs the touch input operation A when the “scroll flag (Scroll_Flg) = oblique direction” is written in the information storage medium 25 by the scroll direction determination process of S110 to S116 described later. to decide. Further, for the detailed oblique direction, the scroll wheel processing unit 23 is determined by the first drag start coordinates (X2s, Y2s) and the drag end coordinates (X2e, Y2e) after dragging at the second contact point in step S108. It is preferable to define the direction of the inclination of the coordinate change angle amount (Δ∠α). For example, when an operation on the scroll wheel SW as shown in the state V in FIG. 21 is performed, the scroll wheel processing unit 23 determines that the diagonally upper left direction is the scroll direction, and stores the “scroll flag ( Write “Scroll_Flg) = oblique left upper direction”. Further, when an operation on the scroll wheel SW as shown in the state W in FIG. 21 is performed, the scroll wheel processing unit 23 determines that the diagonally lower right direction is the scroll direction, and stores the “scroll flag” in the information storage medium 25. “(Scroll_Flg) = diagonally lower right direction” is written.

  In addition, the scroll wheel processing unit 23 performs the touch input operation B when “scroll flag (Scroll_Flg) = horizontal direction or vertical direction” is written in the information storage medium 25 by the scroll direction determination process of S110 to S116 described later. Alternatively, the touch input operation C is determined.

  Further, the scroll wheel processing unit 23 determines that the scroll direction is the horizontal right direction or the vertical downward direction in response to the touch input operation B, and displays “scroll flag (Scroll_Flg) = horizontal right direction” or “scroll” in the information storage medium 25. A flag (Scroll_Flg) = vertically downward is written. Whether the horizontal right direction or the vertical downward direction is determined is determined when “scroll flag (Scroll_Flg) = horizontal direction” is written in the information storage medium 25 by the scroll direction determination process in S110 to S116 described later. The scroll direction is determined as the horizontal right direction, and when “scroll flag (Scroll_Flg) = vertical direction” is written, the scroll direction is determined as the vertical downward direction.

  Further, the scroll wheel processing unit 23 determines that the scroll direction is the horizontal left direction or the vertical upward direction in response to the touch input operation C, and displays “scroll flag (Scroll_Flg) = horizontal left direction” or “scroll” in the information storage medium 25. The flag (Scroll_Flg) = vertically upward ”is written. Whether the horizontal left direction or the vertical upward direction is determined is determined when “scroll flag (Scroll_Flg) = horizontal direction” is written in the information storage medium 25 by the scroll direction determination processing in S110 to S116 described later. The scroll direction is determined to be the horizontal left direction, and when “scroll flag (Scroll_Flg) = vertical direction” is written, the scroll direction is determined to be the vertical upward direction.

  After step S107 or step S108, the operation content determination processing unit 12 determines whether or not the drag of the second finger is the first drag, that is, whether or not the initial flag is “1” (S109). . When it is determined that the drag of the second finger is the first drag, the fixed area determination processing unit 15 coordinates the coordinates of the second contact point on the display screen by the second finger and the drag from the second contact point. Depending on the direction and distance, the scroll direction with respect to the image displayed on the non-fixed area NF including the second contact point and excluding the predetermined fixed area F including the first contact point from the entire display screen of the display unit 5 Is determined (S110).

  When it is determined that the scroll direction in step S110 is an oblique direction, the fixed area determination processing unit 15 performs an oblique direction with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. And the predetermined rectangular area including the first contact point is determined as the fixed area F (S111). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S111).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S111). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = oblique direction” in the information storage medium 25 (S112).

  When it is determined in step S110 that the scroll direction is only the horizontal direction, the fixed area determination processing unit 15 is horizontal with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S113). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S113).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S113). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S114).

  When it is determined that the scroll direction in step S110 is only the vertical direction, the fixed area determination processing unit 15 is vertical with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S115). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S115).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S115). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S116).

  After the scroll flag is written in the information storage medium 25 in step S112, step S114, or step S116, the operation content determination processing unit 12 writes information indicating that “initial flag = 0” in the information storage medium 25. Then, the information of the initial flag is updated (S117).

  After the initial flag information is updated in step S117, in FIG. 22, the scroll wheel processing unit 23 determines that the second finger is predetermined in a predetermined direction at a certain position within the NF outside the fixed area of the display screen of the display unit 5. When it is determined that the touch input operation of dragging a distance has been performed, it is determined whether or not the touch input operation is an operation on the scroll wheel SW (S118).

  When it is determined that the touch input operation in step S118 is not an operation on the scroll wheel SW, the out-of-fixed-region display processing unit 17 performs the operation according to the scroll flag stored in the information storage medium 25 (S119). A scrolled image obtained by scrolling the image displayed on the non-fixed area NF immediately before the second finger dragging in the scroll direction determined by the fixed area determination processing unit 15 is generated and displayed (S120 to S122).

  Specifically, when the scroll flag is in an oblique direction, the fixed area outside display processing unit 17 scrolls the image displayed in the fixed area outside NF immediately before dragging the second finger in the oblique direction. A generated image is generated, and the generated scrolled image is output to the display image generating unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display unit 5 (S120).

  In addition, when the scroll flag is in the horizontal direction, the out-of-fixed-area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the out-of-fixed area NF in the horizontal direction immediately before dragging the second finger. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display unit 5 (S121).

  Further, when the scroll flag is in the vertical direction, the out-of-fixed-region display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the out-of-fixed region NF in the vertical direction immediately before the second finger is dragged. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display unit 5 (S122).

  When it is determined that the touch input operation in step S118 is an operation on the scroll wheel SW, as shown in FIG. 24, the scroll wheel processing unit 23 drags the touch input operation toward the center of the scroll wheel SW. It is determined whether or not the operation is to be performed (S123). Specifically, the scroll wheel processing unit 23 determines whether or not the post-drag coordinates (X2e, Y2e) of the second contact point by the touch input operation in step S118 are substantially the same as the coordinates of the center part of the scroll wheel. Determination is made (S123).

  When it is determined that the coordinates (X2e, Y2e) after dragging of the second contact point by the touch input operation in step S123 are not substantially the same as the coordinates of the center of the scroll wheel SW, the scroll wheel processing unit 23 In accordance with the scroll flag stored in the storage medium 25 (S124), the image displayed on the NF outside the fixed area immediately before dragging the second finger on the scroll wheel SW is displayed in the scroll direction corresponding to the scroll flag. A scrolled image is generated and displayed (S125 to S127).

  Specifically, in step S124, the scroll wheel processing unit 23 refers to the information storage medium 25 in which the scroll flag determined in step S108 is stored, and sets the scroll flag stored in the information storage medium 25. The corresponding scroll direction is determined (S124).

  The scroll wheel processing unit 23 operates in an oblique direction that is the scroll direction determined in step S124 (for example, an obliquely upper left direction when an operation on the scroll wheel SW as shown in the state V in FIG. 21 is performed, When the operation on the scroll wheel SW as shown in the state W of FIG. 5 is performed, the scrolled image displayed on the NF outside the fixed area is displayed according to the rotation angle by the touch input operation in step S118. The out-of-fixed-area display processing unit 17 is instructed to generate a scrolled image scrolled at the scroll speed S2 (S125).

  The non-fixed area display processing unit 17 scrolls the scrolled image displayed in the display area of the non-fixed area NF in an oblique direction at a scroll speed S2 corresponding to the rotation angle based on an instruction from the scroll wheel processing unit 23. A scrolled image is generated (S125). The non-fixed-region display processing unit 17 outputs the generated scrolled image to the display image generating unit 18 (S125). The display image generation unit 18 outputs the output scrolled image to the display control unit 19 (S125). The display control unit 19 displays the output scrolled image on the display screen of the display unit 5 (S125).

  In addition, the scroll wheel processing unit 23 rotates the scrolled image displayed on the NF outside the fixed area in the horizontal right direction or the vertically downward direction determined in step S124 by the touch input operation in step S118. The outside fixed area display processing unit 17 is instructed to generate a scrolled image that is scrolled at a scroll speed S2 corresponding to the angle (S126).

  Based on an instruction from the scroll wheel processing unit 23, the non-fixed area display processing unit 17 displays the scrolled image displayed in the display area of the non-fixed area NF in the horizontal right direction or at the scroll speed S2 corresponding to the rotation angle. A scrolled image scrolled vertically downward is generated (S126). The non-fixed area display processing unit 17 outputs the generated scrolled image to the display image generating unit 18 (S126). The display image generation unit 18 outputs the output scrolled image to the display control unit 19 (S126). The display control unit 19 displays the output scrolled image on the display screen of the display unit 5 (S126).

  Further, the scroll wheel processing unit 23 rotates the scrolled image displayed on the NF outside the fixed area in the horizontal left direction or the vertical upward direction determined in step S124 by the touch input operation in step S118. The outside fixed area display processing unit 17 is instructed to generate a scrolled image scrolled at a scrolling speed S2 corresponding to the angle (S127).

  Based on an instruction from the scroll wheel processing unit 23, the non-fixed-region display processing unit 17 converts the scrolled image displayed in the non-fixed-region NF display region in the horizontal left direction or at the scroll speed S2 corresponding to the rotation angle. A scrolled image scrolled vertically upward is generated (S127). The non-fixed-region display processing unit 17 outputs the generated scrolled image to the display image generating unit 18 (S127). The display image generation unit 18 outputs the output scrolled image to the display control unit 19 (S127). The display control unit 19 displays the output scrolled image on the display screen of the display unit 5 (S127).

  After the scrolled image is displayed according to any of steps S125 to S127, in FIG. 25, the scroll wheel processing unit 23 is in a state where the first finger is touching the fixed region F and the second It is determined whether or not the touch input operation that the finger of the user double-clicks the NF outside the fixed area is performed (S128).

  When it is determined that the touch input operation is performed in step S128, the scroll wheel processing unit 23 determines whether or not the first drag operation is performed, that is, whether the initial flag is “1” (S129). .

  The scroll wheel processing unit 23 determines whether or not the touch input operation in step S128 is an operation using the scroll wheel SW (S130). If it is determined in step S130 that the touch input operation is not an operation using the scroll wheel SW, the scroll wheel processing unit 23 writes information indicating that “wheel flag = 1” in the information storage medium 25. (S131) The scroll wheel SW centered on the second finger outside the fixed area NF where the second finger is double-clicked is displayed (S132).

  If the first finger of the user is touching the fixed area F and the second finger touches the non-fixed area NF and drags a predetermined distance in the predetermined direction, the above-described steps are performed. The operations of S101 to S132 are repeated.

  As described above, the cellular phone 10c according to the fourth embodiment has a predetermined rectangular area including the first contact point touched by the first finger with respect to the image displayed on the display screen of the display unit 5. Is determined as a fixed area F in the entire image, and a display area excluding the fixed area F in the entire image including the second contact point touched by the second finger is determined as an NF outside the fixed area.

  Furthermore, the mobile phone 10c generates a fixed image of a predetermined rectangular area determined as the fixed area F, and displays the image displayed in the display area determined as NF outside the fixed area on the display screen of the display unit 5. A scrolled image is generated that is scrolled in the scroll direction determined according to the coordinates of the second contact point and the drag direction and distance of the second finger. The mobile phone 10 displays a synthesized image obtained by synthesizing the generated fixed image and the scrolled image on the display screen of the display unit 5.

  Furthermore, when the second finger double-clicks the NF outside the fixed area, the mobile phone 10c displays the scroll wheel SW on the NF outside the fixed area. When a touch input operation such as rotation in the left-right direction or dragging in a predetermined direction is performed on the scroll wheel SW, the mobile phone 10c is displayed on the NF outside the fixed area at a scroll speed S2 corresponding to the rotation angle. A scrolled image obtained by scrolling the scrolled image is generated and displayed.

  Therefore, according to the mobile phone 10c of the fourth embodiment, a part of the content displayed on the display screen is fixed according to an intuitive and simple operation, and the fixed part of the display screen is fixed. You can scroll other areas that are not covered. For this reason, the user can intuitively and simply perform finger scrolling and dragging on the scroll direction of the image displayed on the display screen of the display unit 5 in the fixed portion or the display divided portion, or the image displayed outside the fixed region NF. The selection of the fixed area F and the scrolling of the NF outside the fixed area can be easily realized by only the operation of at least two fingers.

  Furthermore, according to the mobile phone 10c, the scroll direction for the scrolled image displayed on the NF outside the fixed area is only the finger movement direction with respect to the scroll wheel SW, and the scroll speed S2 is a movement angle around the scroll wheel. The scroll direction and the scroll speed can be defined according to the user's preference by the visually intuitive operation. For this reason, according to the mobile phone 10c, it is possible to reduce the load of frequent drag operations of the scrolling finger.

21. Description of Operation of Mobile Phone 10d of Fifth Embodiment FIGS. 35 to 37 are flowcharts showing the operation of the mobile phone 10d of the fifth embodiment. Prior to the following description, it is assumed that an arbitrary image is displayed in advance on the display screen of the display unit 5 of the mobile phone 10d.

  In FIG. 35, the operation content determination processing unit 12 determines whether or not a touch input operation has been performed in which the first finger touches the display unit 5 (S141). When it is determined that the touch input operation is performed in step S141, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S142).

  After the information indicating that the initial flag is “1” is written in the information storage medium 25, in FIG. 37, the division position determination processing unit 24 displays the first touched by the first finger on the display screen of the display unit 5. It is determined whether or not a touch input operation of dragging the contact point in a predetermined direction for a predetermined distance has been performed (S143). When it is determined that the touch input operation is not performed in step S143, the operation content determination processing unit 12 touches the display screen of the display unit 5 with both the first finger and the second finger. Is determined (S144).

  If it is determined in step S144 that the touch input operation has been performed, the operation content determination processing unit 12 performs a touch input operation in which the second finger touches the display unit 5 and then drags a predetermined distance in a predetermined direction. It is determined whether or not (S145).

  If it is determined in step S145 that the touch input operation has been performed, the operation content determination processing unit 12 obtains information on the coordinate change amount (ΔX2, ΔY2) of the second contact point dragged based on the touch input operation. The coordinate change amount information is acquired and written in the information storage medium 25 (S146).

  Note that the operation content determination processing unit 12 has the coordinates before dragging (X2s, Y2s) and the coordinates after dragging (X2e, Y2e) of the second contact point when the second finger touches the display unit 5. The coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired based on the information, thereby acquiring information of the coordinate change amount (ΔX2, ΔY2) of the second contact point.

  After the information on the coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired in step S146, in FIG. 36, the operation content determination processing unit 12 determines whether or not the second finger drag is the first drag. That is, it is determined whether or not the initial flag is “1” (S147). When it is determined in step S147 that the drag of the second finger is the first drag, the fixed area determination processing unit 15 determines the coordinates of the second contact point on the display screen by the second finger and the second contact point. The scroll direction with respect to the image displayed on the NF outside the fixed area including the second contact point and excluding the fixed area F including the first contact point from the entire display screen of the display unit 5 according to the drag direction and distance from Is determined (S148).

  Note that the fixed area determination processing unit 15 is based on the coordinates of the second contact point on the display screen of the display unit 5 and the coordinate change amount (ΔX2, ΔY2) of the second contact point acquired in step S146. It is preferable to determine the scroll direction of the image of the non-fixed area NF including the second contact point. For example, when ΔX2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the vertical direction. When ΔY2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the horizontal direction. In addition, when ΔX2 and ΔY2 of the coordinate change amounts (ΔX2, ΔY2) of the second contact point are not substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is an oblique direction.

  When it is determined that the scroll direction in step S148 is an oblique direction, the fixed area determination processing unit 15 performs an oblique direction with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. The predetermined rectangular area including the first contact point is determined as the fixed area F (S149). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S149).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S149). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = oblique direction” in the information storage medium 25 (S150).

  When it is determined in step S148 that the scroll direction is only the horizontal direction, the fixed area determination processing unit 15 is horizontal with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S151). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S151).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S151). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S152).

  When it is determined in step S148 that the scroll direction is only the vertical direction, the fixed area determination processing unit 15 is vertical to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S153). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S153).

  Furthermore, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S153). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S154).

  After the scroll flag is written in the information storage medium 25 in step S149, step S151, or step S153, the operation content determination processing unit 12 writes information indicating that “initial flag = 0” in the information storage medium 25. The information of the initial flag is updated (S155).

  After the initial flag information is updated in step S155, in FIG. 35, the out-of-fixed-region display processing unit 17 drags the second finger in accordance with the scroll flag stored in the information storage medium 25 (S156). A scrolled image obtained by scrolling the image displayed immediately before the non-fixed area NF in the scroll direction determined by the fixed area determination processing unit 15 is generated and displayed (S157 to S159).

  Specifically, when the scroll flag is in an oblique direction, the fixed area outside display processing unit 17 scrolls the image displayed in the fixed area outside NF immediately before dragging the second finger in the oblique direction. A generated image is generated, and the generated scrolled image is output to the display image generating unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S157).

  In addition, when the scroll flag is in the horizontal direction, the non-fixed area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the non-fixed area NF immediately before dragging the second finger in the horizontal direction. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S158).

  In addition, when the scroll flag is in the vertical direction, the outside fixed area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the outside fixed area NF immediately before the second finger is dragged in the vertical direction. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S159).

  After the scrolled image is displayed on the display unit 5, the operation content determination processing unit 12 has performed a touch input operation in which a second finger touches the display unit 5 and then a new distance is dragged in a predetermined direction. It is determined whether or not (S145).

  When it is determined that the touch input operation is not performed in step S145, the operation content determination processing unit 12 determines whether or not the touch input operation that the first finger touches the display unit 5 is performed. (S141).

  When it is determined that the touch input operation is performed in step S141, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S142).

  Thereafter, the division position determination processing unit 24 determines whether or not a touch input operation is performed in which the first contact point touched by the first finger on the display screen of the display unit 5 is dragged by a predetermined distance in a predetermined direction ( S143). When it is determined that the touch input operation is performed in step S143, the division position determination processing unit 24 determines the direction in which the first finger is dragged (S160). The division position determination processing unit 24 can acquire the dragged direction of the first finger from the operation content determination processing unit 12.

  When it is determined in step S160 that the drag direction of the first finger is the horizontal direction, the division position determination processing unit 24 displays the display division boundary line BR in the horizontal direction in which the first finger has dragged. The division position determination processing unit 24 divides the display screen of the display unit 5 into the fixed area F and the non-fixed area NF according to the displayed display division boundary line BR. The division position determination processing unit 24 outputs information indicating that the display is divided to the fixed region determination processing unit 15.

  Further, when the display is divided by the display division boundary line BR, the fixed area determination processing unit 15 includes the display division boundary line BR and touches the first finger based on the information output by the division position determination processing unit 24. The display area of the predetermined rectangular area including the first contact point is determined as the fixed area F, and the display area excluding the fixed area F in the entire display screen of the display unit 5 is determined as the NF outside the fixed area. . It should be noted that which of the two display areas divided by the display division boundary line BR is the fixed area F is preferably defined in advance in the operation of the division position determination processing unit 24. Further, which of the two display areas divided by the display division boundary line BR is the fixed area F is temporarily determined by the division position determination processing unit 24, and two contact points are provided in step S145 described later. That is, when it is determined that there is a touch of the second finger, the fixed area determination processing unit 15 includes the coordinates of the second touch point from the coordinates of the second touch point on the display screen by the second finger. The display area may be NF outside the fixed area, and the display area not including the coordinates of the second contact point may be formally determined as the fixed area F. The determination result is notified by the fixed region determination processing unit 15 to the non-fixed region display processing unit 17 and the fixed region display processing unit 16, and the fixed region F and the fixed region that have been officially determined according to the notification are fixed. A fixed image and a scrolled image respectively displayed on the out-of-area NF are displayed.

  Further, the division position determination processing unit 24 determines that the vertical direction, which is a direction perpendicular to the horizontal direction in which the display division boundary line BR is displayed, is the scroll direction for the scrolled image displayed outside the fixed area ( S161).

  At this time, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area F determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display unit 5 (S161).

  The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S162).

  If it is determined in step S160 that the dragged direction of the first finger is the vertical direction, the split position determination processing unit 24 displays the display split boundary line BR in the vertical direction dragged by the first finger. . The division position determination processing unit 24 divides the display screen of the display unit 5 into the fixed area F and the non-fixed area NF according to the displayed display division boundary line BR. The division position determination processing unit 24 outputs information indicating that the display is divided to the fixed region determination processing unit 15.

  Further, when the display is divided by the display division boundary line BR, the fixed area determination processing unit 15 includes the display division boundary line BR and touches the first finger based on the information output by the division position determination processing unit 24. The display area of the predetermined rectangular area including the first contact point is determined as the fixed area F, and the display area excluding the fixed area F in the entire display screen of the display unit 5 is determined as the NF outside the fixed area. . It should be noted that which of the two display areas divided by the display division boundary line BR is the fixed area F is preferably defined in advance in the operation of the division position determination processing unit 24. Further, which of the two display areas divided by the display division boundary line BR is the fixed area F is temporarily determined by the division position determination processing unit 24, and two contact points are provided in step S145 described later. That is, when it is determined that there is a touch of the second finger, the fixed area determination processing unit 15 includes the coordinates of the second touch point from the coordinates of the second touch point on the display screen by the second finger. The display area may be NF outside the fixed area, and the display area not including the coordinates of the second contact point may be formally determined as the fixed area F. The determination result is notified by the fixed region determination processing unit 15 to the non-fixed region display processing unit 17 and the fixed region display processing unit 16, and the fixed region F and the fixed region that have been officially determined according to the notification are fixed. A fixed image and a scrolled image respectively displayed on the out-of-area NF are displayed.

  Further, the division position determination processing unit 24 determines that the horizontal direction, which is a direction perpendicular to the vertical direction in which the display division boundary line BR is displayed, is the scroll direction for the scrolled image displayed outside the fixed area ( S163).

  At this time, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display unit 5 (S163).

  The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S164).

  After the scroll flag is written in the information storage medium 25 in step S162 or step S164, the operation content determination processing unit 12 writes “initial flag = 0” in the information storage medium 25 to thereby change the initial flag. Information is updated (S165).

  If it is determined that a touch input operation has been performed in which both the first finger and the second finger have touched the display unit 5 and the second finger has been dragged a predetermined distance in a predetermined direction, the above-described steps The operations of S146 to S165 are repeated.

  As described above, the cellular phone 10d according to the fifth embodiment has a predetermined rectangular area including the first contact point touched by the first finger with respect to the image displayed on the display screen of the display unit 5. Is determined as a fixed area F in the entire image, and a display area excluding the fixed area F in the entire image including the second contact point touched by the second finger is determined as an NF outside the fixed area.

  Furthermore, the mobile phone 10d generates a fixed image of a predetermined rectangular area determined as the fixed area F, and displays an image corresponding to the display area determined as NF outside the fixed area on the display screen of the display unit 5 on the second screen. A scrolled image is generated that is scrolled in the scroll direction determined according to the coordinates of the contact point and the drag direction and distance of the second finger. The mobile phone 10 d displays a composite image obtained by combining the generated fixed image and the scrolled image on the display screen of the display unit 5.

  Furthermore, the cellular phone 10d is configured such that the first finger touches the display screen or the first finger touches the fixed area and the second finger touches outside the fixed area. The display division boundary line BR indicating the display division state of the fixed area F and the non-fixed area NF is displayed according to the direction in which the finger is dragged by a predetermined distance. The mobile phone 10d scrolls the scrolled image displayed on the non-fixed area NF in a direction perpendicular to the display direction of the display division boundary line BR in accordance with the drag of the second finger for a predetermined distance.

  Therefore, according to the cellular phone 10d of the fifth embodiment, a part of the content displayed on the display screen is fixed and a fixed portion of the display screen is fixed according to an intuitive and simple operation. You can scroll other areas that are not covered. For this reason, the user can intuitively and simply perform finger scrolling and dragging on the scroll direction of the image displayed on the display screen of the display unit 5 in the fixed portion or the display divided portion, or the image displayed outside the fixed region NF. It is possible to easily perform the selection of the fixed area and the scrolling outside the fixed area with only the operation of at least two fingers.

  Further, according to the mobile phone 10d, display division between the fixed area F and the non-fixed area NF can be realized by an intuitive and simple operation along the direction in which the first finger is dragged a predetermined distance.

  In the cellular phone 10d, in a state where only the first finger is touching the display screen, the display division state of the fixed area F and the non-fixed area NF is changed according to the direction in which the first finger is dragged a predetermined distance. If it is not possible to distinguish between the case of the process of displaying the display division boundary line BR shown and the case of simple scrolling of the entire display screen by dragging the first finger by a predetermined distance, This can be avoided by starting the start position from the edge portion of the display screen or providing a menu operation that clearly indicates that the process is to be performed.

(Sixth embodiment)
22. Description of Configuration of Mobile Phone 10e of Sixth Embodiment FIG. 38 is a block diagram showing an internal configuration of a mobile phone 10e that is an example of the electronic apparatus of the present invention. As shown in FIG. 38, the mobile phone 10e includes a display processing unit 13e having a scroll operation processing unit 14e further including a contact means replacement processing unit 26 in the scroll operation processing unit 14d of the mobile phone 10d of the fifth embodiment.

Since the rest of the configuration excluding the contact means replacement processing unit 26 is the same as that of the cellular phone 10d of the fifth embodiment, the description regarding the same contents is omitted.

23. Description on Operation Overview of Contact Means Replacement Processing Unit 26 FIG. 39 is an explanatory diagram illustrating an example of a touch input operation according to the sixth embodiment, in which the first finger of the user who is in contact with the display division boundary line BR is displayed. An example when changing to the second finger is shown. In the sixth embodiment, the contact means is means for touching the display division boundary line BR. Hereinafter, a user's finger will be described as an example of the contact means, but a stylus pen may be used instead of the finger, for example. In FIG. 39, the image browsing application is operating on the display screen of the display unit 5 of the mobile phone 10e. Also, the image data stored in the information storage medium 25 is displayed on the display screen of the display unit 5 of the mobile phone 10e shown in FIG. Further, in the description of FIG. 39, it is assumed that the fixed area determination processing unit 15 determines that the scroll direction with respect to the scrolled image is the horizontal direction.

  39, the first finger touches the coordinates (X1, Y1) of the first contact point on the display division boundary line BR included in the fixed region F, and the second finger touches the display unit 5. The state of touching the coordinates (X0, Y0) of the second contact point in the fixed area NF excluding the fixed area F in the display screen is shown. When the second finger makes a touch transition to the coordinates (X2, Y2) on the display division boundary line BR as shown in the state N1, the contact means replacement processing unit 26 visually displays the display division boundary line BR. Display in an emphasizable manner. For example, when the display division boundary line BR is displayed in black, the contact means replacement processing unit 26 displays the display division boundary line BR in red. Otherwise, the contact means replacement processing unit 26 may blink the display division boundary line BR. Various other visually emphasizeable modes are applicable.

  The contact means replacement processing unit 26 compares the coordinates (X2, Y2) after the touch transition of the second finger and the first contact points (X1, Y1) touched by the first finger. When it is determined that the X coordinate (X2) of the coordinate after the touch transition of the second finger and the X coordinate (X1) of the first contact point touched by the first finger are substantially equal, the contact means replacement process The unit 26 replaces the coordinates (X2, Y2) after the touch transition of the second finger as the coordinates (X1, Y1) of the new first contact point as shown in the state O1. As a result, the second finger touching the coordinates (X1, Y1) of the first contact point that has been newly replaced is replaced as a new first finger, and the first finger before the replacement. Can release the movement of fingers. Note that FIG. 39 shows an example in which the display division boundary line BR is displayed in the vertical direction, but the above description applies similarly when the display division boundary line BR is displayed in the horizontal direction. be able to.

24. Description on Operation of Mobile Phone 10e of Sixth Embodiment FIGS. 40 to 43 are flowcharts showing the operation of the mobile phone 10e of the sixth embodiment. Prior to the following description, it is assumed that an arbitrary image is displayed in advance on the display screen of the display unit 5 of the mobile phone 10e.

  In FIG. 40, the operation content determination processing unit 12 determines whether or not a touch input operation that the first finger touches the display unit 5 has been performed (S171). When it is determined that the touch input operation is performed in step S171, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S172).

  After the information indicating that the initial flag is “1” is written in the information storage medium 25, in FIG. 42, the division position determination processing unit 24 displays the first touched by the first finger on the display screen of the display unit 5. It is determined whether or not a touch input operation in which the contact point is dragged by a predetermined distance in a predetermined direction has been performed (S173). When it is determined that the touch input operation is not performed in step S173, the operation content determination processing unit 12 touches the display screen of the display unit 5 with both the first finger and the second finger. Is determined (S174).

  If it is determined in step S174 that the touch input operation has been performed, the contact means replacement processing unit 26 touches the coordinates (X1, Y1) of the first contact point touched by the first finger and the second finger. The second contact point (X2, Y2) is compared (S175). Specifically, in this comparison, the X coordinate (X1) of the first contact point and the X coordinate (X2) of the second contact point are substantially equal, and the Y coordinate (Y1) of the first contact point. Whether or not the Y coordinate (Y2) of the second contact point is substantially equal is determined.

  The X coordinate (X1) of the first contact point is completely different from the X coordinate (X2) of the second contact point, and the Y coordinate (Y1) of the first contact point and the Y coordinate (Y2) of the second contact point are different. If it is determined that the two are completely different, the contact means replacement processing unit 26 maintains the coordinates (X2, Y2) as they are without changing the coordinates (X2, Y2) of the second contact point (S176). In other words, in this case, the user's first and second fingers as contact means are not interchanged.

  After step S176, in FIG. 43, the operation content determination processing unit 12 determines whether or not a touch input operation in which the second finger drags a predetermined distance in a predetermined direction after step S176 has been performed (S177). If it is determined in step S177 that the touch input operation has been performed, the operation content determination processing unit 12 obtains information on the coordinate change amount (ΔX2, ΔY2) of the second contact point dragged based on the touch input operation. The coordinate change amount information is acquired and written in the information storage medium 25 (S178).

  Note that the operation content determination processing unit 12 has the coordinates before dragging (X2s, Y2s) and the coordinates after dragging (X2e, Y2e) of the second contact point when the second finger touches the display unit 5. On the basis of the information, the coordinate change amount (ΔX2, ΔY2) of the second contact point is acquired, thereby acquiring the coordinate change amount (ΔX2, ΔY2) of the second contact point.

  The operation content determination processing unit 12 determines whether or not the second finger drag is the first drag, that is, whether or not the initial flag is “1” (S179). When it is determined in step S179 that the drag of the second finger is the first drag, the fixed area determination processing unit 15 determines the coordinates of the second contact point on the display screen by the second finger, and the second contact point. Scrolling with respect to an image displayed outside the fixed area NF including the second contact point and excluding the fixed area F including the first contact point from the entire display screen of the display unit 5 according to the drag direction and distance from The direction is determined (S180).

  Note that the fixed area determination processing unit 15 is based on the coordinates of the second contact point on the display screen of the display unit 5 and the coordinate change amount (ΔX2, ΔY2) of the second contact point acquired in step S146. It is preferable to determine the scroll direction of the image of the non-fixed area NF including the second contact point. For example, when ΔX2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the vertical direction. When ΔY2 of the coordinate change amount (ΔX2, ΔY2) of the second contact point is substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is only the horizontal direction. In addition, when ΔX2 and ΔY2 of the coordinate change amounts (ΔX2, ΔY2) of the second contact point are not substantially zero, the fixed area determination processing unit 15 determines that the scroll direction is an oblique direction.

  When it is determined that the scroll direction in step S180 is an oblique direction, the fixed area determination processing unit 15 performs an oblique direction with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. The predetermined rectangular area including the first contact point is determined as the fixed area F (S181). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S181).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S181). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = oblique direction” in the information storage medium 25 (S182).

  When it is determined in step S180 that the scroll direction is only the horizontal direction, the fixed area determination processing unit 15 is horizontal with respect to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S183). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S183).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S183). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S184).

  When it is determined that the scroll direction is only the vertical direction in step S180, the fixed area determination processing unit 15 is vertical to the image of the non-fixed area NF including the second contact point according to the drag of the second finger. It is determined that scrolling in the direction is performed, and a predetermined rectangular area including the first contact point is determined as the fixed area F (S185). At the same time, the fixed area determination processing unit 15 determines that the display area including the second contact point and excluding the fixed area F from the entire display screen of the display unit 5 is NF outside the fixed area (S185).

  Further, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display screen of the display unit 5 (S186). The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S186).

  After the scroll flag is written in the information storage medium 25 in step S182, step S184, or step S186, the operation content determination processing unit 12 writes information indicating that “initial flag = 0” in the information storage medium 25. The information of the initial flag is updated (S187).

  After the initial flag information is updated in step S187, in FIG. 41, the out-of-fixed-region display processing unit 17 drags the second finger in accordance with the scroll flag stored in the information storage medium 25 (S188). A scrolled image obtained by scrolling the image displayed immediately before the non-fixed area NF in the scroll direction determined by the fixed area determination processing unit 15 is generated and displayed (S189 to S191).

  Specifically, when the scroll flag is in an oblique direction, the fixed area outside display processing unit 17 scrolls the image displayed in the fixed area outside NF immediately before dragging the second finger in the oblique direction. A generated image is generated, and the generated scrolled image is output to the display image generating unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S189).

  In addition, when the scroll flag is in the horizontal direction, the out-of-fixed-area display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the out-of-fixed area NF in the horizontal direction immediately before dragging the second finger. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S190).

  Further, when the scroll flag is in the vertical direction, the out-of-fixed-region display processing unit 17 displays a scrolled image obtained by scrolling the image displayed in the out-of-fixed region NF in the vertical direction immediately before the second finger is dragged. The generated scrolled image is output to the display image generation unit 18. The display image generation unit 18 outputs the scrolled image to the display control unit 19, and the display control unit 19 displays the scrolled image on the display screen of the display unit 5 (S191).

  After the scrolled image is displayed on the display unit 5, the operation content determination processing unit 12 has performed a touch input operation in which a second finger touches the display unit 5 and then a new distance is dragged in a predetermined direction. It is determined whether or not (S177).

  When it is determined that the touch input operation is not performed in step S177, the operation content determination processing unit 12 determines whether or not the touch input operation that the first finger touches the display unit 5 is performed. (S171).

  When it is determined that the touch input operation is performed in step S171, the operation content determination processing unit 12 determines the coordinates (X1, Y1) of the first contact point touched by the first finger based on the touch input operation. The information is acquired, and the coordinate information of the first contact point and the information indicating “initial flag (Init_Flg) = 1” are written in the information storage medium 25 (S172).

  Thereafter, the division position determination processing unit 24 determines whether or not a touch input operation is performed in which the first contact point touched by the first finger on the display screen of the display unit 5 is dragged by a predetermined distance in a predetermined direction ( S173). When it is determined that the touch input operation is performed in step S173, the division position determination processing unit 24 determines the direction in which the first finger is dragged (S197). The division position determination processing unit 24 can acquire the dragged direction of the first finger from the operation content determination processing unit 12.

  If it is determined in step S197 that the drag direction of the first finger is the horizontal direction, the division position determination processing unit 24 displays the display division boundary line BR in the horizontal direction in which the first finger has dragged. The division position determination processing unit 24 divides the display screen of the display unit 5 into the fixed area F and the non-fixed area NF according to the displayed display division boundary line BR. The division position determination processing unit 24 outputs information indicating that the display is divided to the fixed region determination processing unit 15.

  Further, when the display is divided by the display division boundary line BR, the fixed area determination processing unit 15 includes the display division boundary line BR and touches the first finger based on the information output by the division position determination processing unit 24. The display area of the predetermined rectangular area including the first contact point is determined as the fixed area F, and the display area excluding the fixed area F in the entire display screen of the display unit 5 is determined as the NF outside the fixed area. . It should be noted that which of the two display areas divided by the display division boundary line BR is the fixed area F is preferably defined in advance in the operation of the division position determination processing unit 24. Further, which of the two display areas divided by the display division boundary line BR is the fixed area F is provisionally determined by the division position determination processing unit 24, and the user who is a contact means in step S176 described later. When it is determined that there are two contact points in a state where the first finger and the second finger are not reciprocally exchanged, the fixed area determination processing unit 15 causes the second finger to Based on the coordinates of the two contact points on the display screen, the display area including the coordinates of the second contact point is determined as a non-fixed area NF, and the display area not including the coordinates of the second contact point is formally determined as the fixed area F. You may do it. The determination result is notified by the fixed region determination processing unit 15 to the non-fixed region display processing unit 17 and the fixed region display processing unit 16, and the fixed region F and the fixed region that have been officially determined according to the notification are fixed. A fixed image and a scrolled image respectively displayed on the out-of-area NF are displayed.

  Further, the division position determination processing unit 24 determines that the vertical direction, which is a direction perpendicular to the horizontal direction in which the display division boundary line BR is displayed, is the scroll direction for the scrolled image displayed outside the fixed area ( S198).

  At this time, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display unit 5 (S198).

  The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = vertical direction” in the information storage medium 25 (S199).

  If it is determined in step S197 that the dragged direction of the first finger is the vertical direction, the split position determination processing unit 24 displays the display split boundary line BR in the vertical direction dragged by the first finger. . The division position determination processing unit 24 divides the display screen of the display unit 5 into the fixed area F and the non-fixed area NF according to the displayed display division boundary line BR. The division position determination processing unit 24 outputs information indicating that the display is divided to the fixed region determination processing unit 15.

  Further, when the display is divided by the display division boundary line BR, the fixed area determination processing unit 15 includes the display division boundary line BR and touches the first finger based on the information output by the division position determination processing unit 24. The display area of the predetermined rectangular area including the first contact point is determined as the fixed area F, and the display area excluding the fixed area F in the entire display screen of the display unit 5 is determined as the NF outside the fixed area. . It should be noted that which of the two display areas divided by the display division boundary line BR is the fixed area F is preferably defined in advance in the operation of the division position determination processing unit 24. Further, which of the two display areas divided by the display division boundary line BR is the fixed area F is provisionally determined by the division position determination processing unit 24, and the user who is a contact means in step S176 described later. When it is determined that there are two contact points in a state where the first finger and the second finger are not reciprocally exchanged, the fixed area determination processing unit 15 causes the second finger to Based on the coordinates of the two contact points on the display screen, the display area including the coordinates of the second contact point is determined as a non-fixed area NF, and the display area not including the coordinates of the second contact point is formally determined as the fixed area F. You may do it. The determination result is notified by the fixed region determination processing unit 15 to the non-fixed region display processing unit 17 and the fixed region display processing unit 16, and the fixed region F and the fixed region that have been officially determined according to the notification are fixed. A fixed image and a scrolled image respectively displayed on the out-of-area NF are displayed.

  Further, the division position determination processing unit 24 determines that the horizontal direction, which is a direction perpendicular to the vertical direction in which the display division boundary line BR is displayed, is the scroll direction for the scrolled image displayed outside the fixed area ( S200).

  At this time, the fixed area display processing unit 16 generates a fixed image to be displayed in the fixed area determined by the fixed area determination processing unit 15, and outputs the generated fixed image to the display image generation unit 18. The display image generation unit 18 outputs the fixed image to the display control unit 19, and the display control unit 19 displays the fixed image on the display unit 5 (S200).

  The fixed area determination processing unit 15 writes information indicating that “scroll flag (Scroll_Flg) = horizontal direction” in the information storage medium 25 (S201).

  After the scroll flag is written in the information storage medium 25 in step S162 or step S164, the operation content determination processing unit 12 writes information indicating that “initial flag = 0” in the information storage medium 25 (S202).

  After the information indicating that “initial flag = 0” is written in the information storage medium 25, the operation content determination processing unit 12 performs touch input that both the first finger and the second finger touch the display unit 5. It is determined whether or not an operation has been performed (S174).

  If it is determined in step S174 that the touch input operation has been performed, the contact means replacement processing unit 26 touches the coordinates (X1, Y1) of the first contact point touched by the first finger and the second finger. The second contact point (X2, Y2) is compared (S175). As described above, in this comparison, the X coordinate (X1) of the first contact point and the X coordinate (X2) of the second contact point are substantially equal, and the Y coordinate (Y1 of the first contact point). ) And the Y coordinate (Y2) of the second contact point are determined as to whether or not one of them is established.

  When it is determined that the X coordinate (X1) of the first contact point is substantially equal to the X coordinate (X2) of the second contact point, the contact means replacement processing unit 26 sets a scroll flag in the information storage medium 25 in step S200. It is determined whether or not information indicating the horizontal direction is stored (S194). If it is determined in step S200 that the information storage medium 25 does not store information indicating that the scroll flag is in the horizontal direction, the contact means replacement processing unit 26 uses the coordinates (X2, Y2) of the second contact point. The coordinates (X2, Y2) are fixed and maintained without being changed (S176). In other words, in this case, the user's first and second fingers as contact means are not interchanged.

  On the other hand, if it is determined in step S200 that information indicating that the scroll flag is in the horizontal direction is stored in the information storage medium 25, the contact means replacement processing unit 26 displays the information on the display screen of the display unit 5 in step S200. The displayed display division boundary line BR is displayed in a manner that can be visually emphasized (S193).

  If it is determined that the Y coordinate (Y1) of the first contact point and the Y coordinate (Y2) of the second contact point are substantially equal, the contact means replacement processing unit 26 scrolls to the information storage medium 25 in step S199. It is determined whether information indicating that the flag is in the vertical direction is stored (S192). If it is determined in step S199 that information indicating that the scroll flag is in the vertical direction is not stored in the information storage medium 25, the contact means replacement processing unit 26 uses the coordinates (X2, Y2) of the second contact point. The coordinates (X2, Y2) are fixed and maintained without being changed (S176). In other words, in this case, the user's first and second fingers as contact means are not interchanged.

  On the other hand, if it is determined in step S199 that information indicating that the scroll flag is in the vertical direction is stored in the information storage medium 25, the contact means replacement processing unit 26 displays the information on the display screen of the display unit 5 in step S199. The displayed display division boundary line BR is displayed in a manner that can be visually emphasized (S193).

  After the display division boundary line BR is displayed in such a manner that it can be visually emphasized, the contact means replacement processing unit 26 detects that the finger touching the display screen of the display unit 5 is one of the contact points of the second finger. It is determined whether or not a touch input operation is performed (S195). That is, in this step S195, by the touch input operation, the first contact point of the first finger is released, and the second contact point of the second finger is replaced as a new first contact point of the first finger. It is determined whether or not.

  When it is determined that the touch input operation is performed in step S195, the contact means replacement processing unit 26 uses the coordinates (X2, Y2) of the second contact point of the second finger in the comparison in step S175 in the touch input operation. The coordinates (X1, Y1) of the first contact point of the new first finger are replaced (S196). Thereby, the finger used as the second finger before the replacement in step S196 can be used as the first finger after the replacement, and the finger used as the first finger before the replacement in step S196 can be used. It is not necessary to use after replacement, and can be used for other operations.

  If it is determined in step S174 that a touch input operation has been performed in which both the first finger and the second finger touch the display screen of the display unit 5, the processes from step S175 to S202 are repeated.

  As described above, the mobile phone 10e according to the sixth embodiment has a predetermined rectangular area including the first contact point touched by the first finger on the image displayed on the display screen of the display unit 5. Is determined as a fixed area F in the entire image, and a display area excluding the fixed area F in the entire image including the second contact point touched by the second finger is determined as an NF outside the fixed area.

  Further, the mobile phone 10e generates a fixed image of a predetermined rectangular area determined as the fixed area F, and displays an image corresponding to the display area determined as the non-fixed area NF on the display screen of the display unit 5. A scrolled image is generated that is scrolled in the scroll direction determined according to the coordinates of the contact point and the drag direction and distance of the second finger. The cellular phone 10e displays a synthesized image obtained by synthesizing the generated fixed image and the scrolled image on the display screen of the display unit 5.

  Further, the mobile phone 10e is configured such that the first finger only touches the display screen or the first finger touches the fixed area and the second finger touches outside the fixed area. The display division boundary line BR indicating the display division state of the fixed area F and the non-fixed area NF is displayed according to the direction in which the finger is dragged by a predetermined distance. The mobile phone 10e scrolls the scrolled image displayed outside the fixed area in a direction perpendicular to the display direction of the display division boundary line BR in accordance with the drag of the second finger for a predetermined distance.

  Furthermore, when the display division boundary line BR is displayed, the mobile phone 10e is configured such that the X coordinate or the Y coordinate of the second contact point newly touched by the second finger is touched by the first finger. When it is determined that the contact point is approximately equal to the X coordinate or the Y coordinate, the second finger touching the second contact point is replaced with the first finger touching the first contact point.

  Therefore, according to the mobile phone 10e of the sixth embodiment, a part of the contents displayed on the display screen is fixed and the fixed part of the display screen is fixed according to an intuitive and simple operation. You can scroll other areas that are not covered. For this reason, the user can intuitively and simply perform finger scrolling and dragging on the scroll direction of the image displayed on the display screen of the display unit 5 in the fixed portion or the display divided portion, or the image displayed outside the fixed region NF. The selection of the fixed area F and the scrolling of the NF outside the fixed area can be easily realized by only the operation of at least two fingers.

  Further, according to the mobile phone 10e, display division between the fixed area F and the non-fixed area NF can be realized by an intuitive and simple operation along the direction in which the first finger is dragged a predetermined distance.

  Further, according to the mobile phone 10e, the second finger can be interchanged as the first finger by an intuitive and simple operation of replacing the second contact point and the first contact point. Further, the replaced first finger can be used for other operations.

  In each of the embodiments described above, the fixed area determination processing unit 15 performs the oblique direction and the horizontal direction according to the coordinates of the second contact point with respect to the display screen of the display unit 5 and the drag direction and distance of the second contact point. In the case where scrolling is possible in either the vertical direction or the vertical direction, the scroll flag (Scroll_Flg) is set in the information storage medium 25 in accordance with the scrollable direction. However, the fixed area determination processing unit 15 may set the scroll flag in the information storage medium 25 in an oblique direction, a horizontal direction, or a vertical direction according to the explicit drag direction of the second finger.

  In each of the above-described embodiments, the predetermined range AR indicating the fixed area in the image displayed on the display unit 5 is described as a rectangle.

That is, in the state I in FIG. 8, a flower bed image is displayed as a fixed image corresponding to the fixed area F, and a night view image is displayed as a scrolled image at the moment when inertial scrolling is performed in the horizontal left direction. Suppose that it is in a state. In such a state I, when the second finger touches a certain position within the NF outside the fixed area where the scrolled image is displayed on the display screen, the scroll stop processing unit 21 moves to the NF outside the fixed area. The execution of the inertial scrolling in the horizontal left direction that is being executed is stopped. Here, as shown in the state J ′, the scroll stop processing unit 21 displays the night scene image displayed as the scrolled image at the moment when the execution of the inertial scroll in the horizontal left direction is stopped, and the fixed area F. The fixed area display processing unit 16 and the outside fixed area display processing unit 17 may be instructed to display the displayed flower bed images on the display unit 5 so as to have the same size.

  In this case, the fixed area display processing unit 16 generates the flower bed image displayed in the fixed area F based on the instruction output by the fixed area determination processing unit 15, and outputs the flower bed image to the display image generation unit 18. To do. Further, the non-fixed area display processing unit 17 generates a night scene image that is a scrolled image displayed on the non-fixed area NF based on the instruction output by the fixed area determination processing unit 15, and the night scene image is displayed. The image is output to the display image generation unit 18. The display image generation unit 18 outputs a composite image (see state J ′) in which the output fixed image and scrolled image have the same size to the display control unit 19. The display control unit 19 displays the output composite image on the display screen of the display unit 5.

  In each of the above-described embodiments, the cellular phones 10 to 10e are described as examples. However, the electronic device of the present invention is not limited to the mobile phones 10 to 10e, and can be widely applied to electronic devices such as a PC (Personal Computer) and a digital camera.
