  Embodiments of the present invention will be described with reference to the drawings. The embodiments described below do not limit the invention according to the claims. In addition, all of the constituent elements described in the embodiments are not necessarily essential to the solving means of the invention. The same code | symbol has shown the same component through several figures.

(Embodiment 1)
With reference to FIG.1 and FIG.2, the display control apparatus 1 which concerns on Embodiment 1 of this invention is demonstrated. FIG. 1 is a block diagram showing the display control device 1. FIG. 2 shows scroll control executed by the display control device 1. The display control device 1 is, for example, a smartphone or a tablet PC (Personal Computer).

  The display control device 1 includes a control unit 10, a display unit 20, and a touch panel 30 as a detection unit. The control unit 10 includes a CPU (Central Processing Unit) and a main storage device (for example, a semiconductor memory). The control unit 10 functions as various functional units when the CPU executes a control program stored in the main storage device.

  The display unit 20 is a liquid crystal display, for example. Display unit 20 includes a display surface 20A. The display unit 20 displays the scroll target 40. The scroll target 40 includes information. The information is, for example, an image and / or text. In the present embodiment, the scroll target 40 includes text.

  The touch panel 30 detects a first contact operation A1 by an object to be detected on the display surface 20A of the display unit 20. The detected object is, for example, a finger of a user who operates the display control device 1 or a touch pen.

  The first contact operation A1 is an operation in which the object to be detected moves in a direction toward the end portion 40A of the scroll target 40 while contacting the display surface 20A. The first contact operation A1 of the scroll target 40 is, for example, a slide operation, a scroll operation, or a swipe operation on the display surface 20A by the detected object. The end portion 40 </ b> A of the scroll target 40 is an arbitrary end portion among a plurality of end portions constituting the scroll target 40. In the present embodiment, the end 40A of the scroll target 40 extends in a direction along the short side of the display surface 20A. The size of the end 40A of the scroll target 40 along the long side of the display surface 20A is arbitrarily set.

  The control unit 10 determines whether or not the length L of the scroll target 40 along the scrolling direction of the scroll target 40 is equal to or greater than a threshold value. In the present embodiment, the scroll target 40 scrolls in a direction along the long side of the display surface 20A. Therefore, the control unit 10 determines whether or not the length L of the scroll target 40 along the long side of the display surface 20A is greater than or equal to the threshold value. The threshold can be arbitrarily set by the user.

  When it is determined that the length L is equal to or greater than the threshold value, the control unit 10 scrolls to scroll to the end 40A of the scroll target 40 in response to the touch panel 30 detecting the first contact operation A1. The object 40 is controlled. At this time, the control unit 10 controls the scroll target 40 without depending on the physical quantity based on the first contact operation A1. The physical quantity based on the first contact operation A1 is, for example, the pressing force applied to the display surface 20A by the detected object, the distance moved while the detected object is in contact with the display surface 20A, and the detected object is in contact with the display surface 20A. It is the time to move and the speed at which the object to be detected moves while contacting the display surface 20A. The scroll speed V10 of the scroll target 40 is constant. The scroll speed V10 is the amount of movement of the scroll target 40 that scrolls per unit time in the present embodiment.

  When the scroll target 40 is scrolled to the end 40 </ b> A, the display unit 20 displays the end 40 </ b> A of the scroll target 40. In the present embodiment, when the scroll target 40 is scrolled to the end portion 40A, the display unit 20 displays a character string indicating “ZZZ Company” adjacent to the end portion 40A.

  On the other hand, when it is determined that the length L is less than the threshold value, in response to the touch panel 30 detecting the first contact operation A1, the control unit 10 decreases the scroll speed V10 over time. The scroll target 40 is controlled so as to be directed toward the end 40A of the scroll target 40. For example, the control unit 10 reduces the scroll speed V10 at a constant rate or decreases the scroll speed V10 at an arbitrary rate as time elapses. The rate at which the scroll speed V10 is reduced depends on, for example, the physical quantity based on the first contact operation A1. By reducing the scroll speed V10 as time elapses, the scroll target 40 may stop before being scrolled to the end 40A. In some cases, the scroll target 40 does not stop until it is scrolled to the end 40A.

  According to the present embodiment, if the length L of the scroll target 40 along the scroll direction is equal to or greater than the threshold value, the end of the scroll target 40 does not depend on the physical quantity based on the first contact operation A1 on the display surface 20A. The scroll target 40 is controlled so as to scroll to the section 40A. Therefore, it is unnecessary to repeat the first contact operation A1 on the display surface 20A, and the scroll target 40 is controlled to scroll to the end 40A of the scroll target 40. As a result, it is possible to reduce the burden of operation when scrolling the scroll target 40 to the end 40A of the scroll target 40.

  In addition, according to the present embodiment, if the length L of the scroll target 40 along the scroll direction is less than the threshold value, the scroll is performed as time passes in response to the detection of the first contact operation A1. The scroll target 40 is scrolled while reducing the speed V10. Therefore, the visibility of the scroll target 40 when scrolling is improved. As a result, it is possible to reduce the burden of operation when searching for desired information by scrolling the scroll target 40.

  Furthermore, according to the present embodiment, when the length L of the scroll target 40 along the scroll direction is equal to or greater than the threshold value, the scroll speed V10 is constant. That is, the scroll speed V10 is maintained without decreasing with time. Therefore, it is possible to prevent the time for scrolling the scroll target 40 from reaching the end portion 40A of the scroll target 40 from becoming long.

  Next, the scroll speed that is changed in response to the second contact operation A2 will be described with reference to FIGS. 3 (a) and 3 (b). FIG. 3A and FIG. 3B show the scroll speed changed in response to the second contact operation A2. In the present embodiment, the length L is equal to or greater than a threshold value.

  As shown in FIG. 3A, in response to the touch panel 30 detecting the first contact operation A1, the control unit 10 is configured to scroll to the end 40A of the scroll target 40 at a constant scroll speed V10. The scroll target 40 is controlled.

  As illustrated in FIG. 3B, the touch panel 30 detects the second contact operation A2 while the scroll target 40 is scrolling. The second contact operation A2 is a contact operation on the display surface 20A by the detected object detected by the touch panel 30 while the scroll target 40 is scrolled. The second contact operation A2 is an operation in which, for example, the object to be detected moves in a direction toward the end 40A of the scroll target 40 while contacting the display surface 20A. The second contact operation A2 of the scroll target 40 is, for example, a slide operation, a scroll operation, or a swipe operation on the display surface 20A by the detected object.

  In response to the detection of the second contact operation A2, the control unit 10 scrolls so that the scroll target 40 scrolls at a scroll speed V20 that is different from the scroll speed V10 before the second contact operation A2 is detected. The object 40 is controlled. The scroll speed V20 is greater than the scroll speed V10 before the second contact operation A2 is detected. Further, while the scroll target 40 is scrolling, the touch panel 30 may detect the second contact operation A2 a plurality of times. In this case, the control unit 10 may increase the scroll speed V10 each time the second contact operation A2 is detected.

  For example, the control unit 10 increases the scroll speed V10 at a constant rate or increases the scroll speed V10 at an arbitrary rate in response to the detection of the second contact operation A2. When the scroll speed V10 is increased at a constant rate, if the increase rate is 2.0, the scroll speed V20 is V10 × 2.0.

  While the scroll target 40 is scrolled, the control unit 10 controls the scroll target 40 so that the touch target 30 stops the scroll target 40 in response to detecting the fourth contact operation A4. For example, the fourth contact operation A4 is an operation in which the object to be detected contacts the display surface 20A without moving on the display surface 20A. The fourth contact operation A4 of the scroll target 40 is, for example, a tap operation, a double tap operation, or a long tap operation on the display surface 20A by the detected object.

  According to this embodiment, in response to the detection of the second contact operation A2, the scroll speed V10 of the scroll target 40 increases. Therefore, the time for scrolling the scroll target 40 to the end 40A of the scroll target 40 is shortened. As a result, the operation burden when scrolling the scroll target 40 to the end 40A of the scroll target 40 can be further reduced.

  Further, according to the present embodiment, the scroll target 40 is controlled to stop in response to the detection of the fourth contact operation A4 while the scroll target 40 scrolls. Therefore, the scroll of the scroll target 40 can be stopped only by touching the display surface 20A at the timing desired by the user. As a result, the operation burden when scrolling the scroll target 40 can be reduced.

  Next, scroll control executed by the display control apparatus 1 according to the first embodiment will be described with reference to FIGS. By executing steps S10 to S110, the scroll target 40 is controlled to scroll.

  In step S <b> 10, the display unit 20 displays the scroll target 40. In step S20, the control unit 10 determines whether or not the length L of the scroll target 40 is equal to or greater than a threshold value. In step S20, when the control unit 10 makes an affirmative determination (YES), that is, when the length L is equal to or greater than the threshold, the process proceeds to step S30.

  In step S30, the touch panel 30 detects the first contact operation A1. In step S40, the control unit 10 controls the scroll target 40 so that the scroll target 40 scrolls to the end 40A of the scroll target 40 at a constant scroll speed V10.

  In step S50, the control unit 10 determines whether or not the second contact operation A2 is detected while the scroll target 40 is scrolled. In step S50, when the control unit 10 makes a positive determination (YES), that is, when the touch panel 30 detects the second contact operation A2 while the scroll target 40 is scrolled, the process proceeds to step S60. In step S60, the control unit 10 increases the scroll speed V10. That is, the control unit 10 scrolls the scroll target 40 at a scroll speed V20 different from the scroll speed V10. On the other hand, when the control unit 10 makes a negative determination (NO) in step S50, that is, when the touch panel 30 does not detect the second contact operation A2 while the scroll target 40 is scrolled, the process proceeds to step S55. move on. In step S55, the scroll speed V10 is maintained.

  In step S70, the control unit 10 determines whether or not the touch panel 30 has detected the fourth contact operation A4. If the control unit 10 makes a positive determination (YES) in step S70, the process proceeds to step S90. In step S90, the control unit 10 stops the scroll target 40.

  On the other hand, when the control unit 10 makes a negative determination (NO) in step S70, the process proceeds to step S80. In step S <b> 80, the control unit 10 determines whether or not the scroll target 40 has scrolled to the end 40 </ b> A of the scroll target 40. If the control unit 10 makes a negative determination (NO) in step S80, the process returns to step S50. That is, in step S80, when the scroll target 40 is not scrolled to the end 40A, the control unit 10 continues scrolling the scroll target 40. On the other hand, when the control unit 10 makes a positive determination (YES) in step S80, the process proceeds to step S90.

  In step S20, when the control unit 10 makes a negative determination (NO), that is, when the length L of the scroll target 40 is less than the threshold, the process proceeds to step S100. In step S100, the touch panel 30 detects the first contact operation A1. In step S110, the control unit 10 scrolls the scroll target 40 while decreasing the scroll speed V10 with the passage of time. Thereafter, the process proceeds to step S90.

  As described above with reference to FIGS. 1 to 4, according to the first embodiment, based on the result of determining whether or not the length L of the scroll target 40 along the scroll direction is greater than or equal to the threshold value. Thus, it is determined whether or not the scroll speed V10 is maintained. Accordingly, the scroll target 40 is scrolled at a speed corresponding to the length L of the scroll target 40. As a result, it is possible to reduce the burden of operation when scrolling the scroll target 40 to the end 40A of the scroll target 40.
