Description

  The technology disclosed in this specification relates to a program for an image display device that displays various images, an image display device, and a control method for the image display device.

  As a device for displaying a lot of information on one touch panel, for example, there is a method of performing scroll display. For example, a list may be displayed by displaying a plurality of various object images (for example, icon images, list images, etc.) for receiving various processing execution start instructions on the touch panel. In this case, when one of the object images in the list is pressed, the pressed object image is highlighted (for example, highlighted) to notify that the object image is selected. After that, the list is scrolled in response to a drag operation (moving while touching the screen with your finger or stylus pen) or flick operation (moving your finger or stylus to lightly touch the screen). The On the screen after scroll display, an object image different from the object image displayed on the screen before scroll display is displayed. When a touch operation (an operation in which a press input is terminated without being dragged after being input by pressing) is input to any object image, the process assigned to the object image to which the touch operation is input An execution start command is accepted. Moreover, the technique of patent document 1 is disclosed as a technique of scroll-displaying a screen.

JP 2012-14524 A

  In the technique for performing the scroll display as described above, in either case of inputting a touch operation to select an object image and inputting a drag operation or a flick operation to scroll the list, first, The start of pressing the object image in the list is detected. Then, in response to the detection of the start of pressing, the pressed object image is highlighted. If the movement of the pressed point is detected after the start of pressing is detected, it is determined that a drag operation or a flick operation has been input, and the highlighting of the object image is terminated. In this case, the pressed object image is highlighted for a short period from the time when the start of pressing is detected until the time when the movement of the pressing point is detected. Then, a visual effect is given to the user such that the pressed object image flickers (lights up for a very short time), which may cause visual discomfort to the user. In this specification, the technique which can eliminate such inconvenience is provided.

  An image display apparatus comprising: display means for displaying an image; and coordinate detection means for detecting indicated coordinates which are coordinates indicating a position where the indicator is in contact with the display area of the display means. Is a readable program in which a scroll area is defined in the display area of the display means, and a plurality of object images for receiving various processing execution start instructions are arranged in a line in the scroll area. The object display control means to be displayed on the display means, and the object image is scroll-displayed in the first direction along the row of object images, or in the second direction along the row of object images opposite to the first direction. The scroll display control means and the coordinates where the indicated coordinates detected by the coordinate detection means are no longer detected are the objects. When the coordinates corresponding to the target image are functioning as the processing execution means for executing the processing assigned to the corresponding object image, the object display control means When the initial designated coordinates, which are the coordinates where the detection of the image is started, are the coordinates corresponding to the specific object image that is any one of the plurality of object images, the specific object image is highlighted and scrolled. When the coordinate detection unit detects the start of movement of the designated coordinates in the direction corresponding to the first direction or the second direction after the specific object image is highlighted by the object display control unit, the control unit In response to the movement of the coordinates in the first direction or the second direction, execution of scroll display is started. The first display control means is set based on a movement start speed that is a speed when the designated coordinates start moving from the initial designated coordinates from the time when the scroll display control means starts to execute the scroll display. The highlighting of the specific object image is terminated according to the elapse of time.

  In the program described in this specification, the highlighting of the specific object image is terminated when the first predetermined time has elapsed since the scroll display control unit started executing the scroll display. Thereby, it is possible to lengthen the period during which the specific object image is highlighted as compared with the case where the highlighting of the specific object image is terminated when the execution of the scroll display is started. Therefore, it is possible to alleviate the visual effect that the pressed object image flickers (lights up for a very short time), so that it is possible to prevent the user from having a visual discomfort. It becomes.

  As the movement start speed of the designated coordinates increases, the scroll speed increases and the selection of the object image becomes difficult. Therefore, even if the specific object image is highlighted, the user is informed that the specific object image is still selected. The risk of misperception is reduced. According to the program of claim 2, since the period during which the specific object image is highlighted can be lengthened as the movement start speed of the designated coordinates increases, the user can even select the specific object image. It is possible to alleviate a visual effect that causes the pressed object image to flicker without giving a false perception that the object is pressed.

  According to the program of claim 3, when the specific object image is highlighted, when the frame is out of the scroll area and is no longer displayed on the display unit, the specific object image is not highlighted. Thus, it is possible to frame in the scroll area again. Thereby, since the highlighting of the specific object image can be ended by out-of-frame, it is possible to prevent the user from having a visual effect that the object image flickers.

  According to the program of the fourth aspect, it is possible to end the highlighting of the specific object image in a fade-out manner in which the highlighting of the specific object image is gradually ended. As a result, it is possible to alleviate a visual effect that causes the object image to flicker.

  According to the program of the fifth aspect, the specific object image is highlighted in response to the second predetermined time having elapsed from the detection start time of the initial designated coordinates. Therefore, when the execution of the scroll display is started before the second predetermined time has elapsed from the detection start time of the initial designated coordinates, the specific object image is not highlighted. As a result, it is possible to prevent the user from having a visual effect that causes the object image to flicker.

  In the program according to the sixth aspect, the highlighting of the specific object image is terminated when the third predetermined time has elapsed since the scroll display control means started executing the scroll display. Thereby, it is possible to lengthen the period during which the specific object image is highlighted as compared with the case where the highlighting of the specific object image is terminated when the execution of the scroll display is started. Therefore, it is possible to alleviate the visual effect that the pressed object image flickers (lights up for a very short time), so that it is possible to prevent the user from having a visual discomfort. It becomes.

  As the display area of the specific object image increases, the visual effect that causes the object image to flicker increases. According to the program according to claim 7, since the period during which the specific object image is highlighted can be lengthened as the display area of the specific object image increases, the pressed object image flickers. It is possible to alleviate such visual effects.

  According to the program according to claim 8, when the specific object image is highlighted, when the frame is out of the scroll area and is not displayed on the display means, the specific object image is not highlighted. Thus, it is possible to frame in the scroll area again. Thereby, since the highlighting of the specific object image can be ended by out-of-frame, it is possible to prevent the user from having a visual effect that the object image flickers.

  According to the program of the ninth aspect, it is possible to end the highlighting of the specific object image in a fade-out manner in which the highlighting of the specific object image is gradually ended. As a result, it is possible to alleviate a visual effect that causes the object image to flicker.

  According to the program of the tenth aspect, the specific object image is highlighted when the second predetermined time has elapsed from the detection start time of the initial designated coordinates. Therefore, when the execution of the scroll display is started before the second predetermined time has elapsed from the detection start time of the initial designated coordinates, the specific object image is not highlighted. As a result, it is possible to prevent the user from having a visual effect that causes the object image to flicker.

  Note that an image display device for realizing the above program, a method for controlling the image display device, and a computer-readable recording medium for storing the computer program are also novel and useful.

<Example>
FIG. 1 shows a block diagram of a multi-function device 10 (also referred to as Multifunction Peripheral (MFP)) according to the present embodiment.

<Configuration of multi-function device 10>
The multi-function device 10 according to the present embodiment is a device having a printer function, a scanner function, a copy function, a facsimile function, a telephone function, and the like. The multi-function device 10 includes a control unit 12, a panel 50, a coordinate detection unit 51, a printing unit 54, a scanning unit 56, a FAX unit 58, a network interface 60, and the like. The control unit 12 includes a CPU 14, a ROM 16, a RAM 30, an NVRAM (Non Volatile RAM) 40, and the like.

  The CPU 14 executes various processes according to programs stored in the ROM 16. The processing executed by the CPU 14 will be described in detail later. The ROM 16 stores an image display program 18 for controlling basic operations of the multi-function device 10.

  As shown in FIG. 1, a panel 50 is provided on the upper surface front side of the multi-function device 10. Various images are displayed on the panel 50 using an application program interface (API) of the image display program 18. The left-right direction (lateral direction) with respect to the front position of the panel 50 is the x direction. The front-rear direction (vertical direction) relative to the front position of the panel 50 is the y direction. A coordinate detector 51 having a transparent flat plate portion is provided on the surface of the panel 50 so as to cover the panel 50. The coordinate detection unit 51 has a function of detecting designated coordinates, which are coordinates indicating a position at which an indicator (eg, a user's fingertip, stylus (touch panel pen), etc.) is touched or approached. The panel 50 and the coordinate detection unit 51 function as a so-called touch panel.

  The RAM 30 is a volatile memory, and is a storage area for storing various data generated in the process of executing processing according to the image display program 18. Examples of data stored in the RAM 30 include a press determination flag and a moving flag. The press determination flag is information that is “ON” when any list image is pressed, and “OFF” when any list image is not pressed. The moving flag is information that is “ON” when the designated coordinate is moving, and is “OFF” when the designated coordinate is not moving.

  The RAM 30 stores a list image table TB1. The list image table TB1 is a table that stores various types of information for each of the plurality of list images displayed on the panel 50. FIG. 6 shows an example of the list image table TB1 in the present embodiment. The list image table TB1 includes a list number 101, a list character string 103, a region coordinate 104, a display state flag 105, a list pressing state flag 106, a reverse display flag 107, a list display width 108, a list display height 109, and an execution process content 110. , Remember.

  The list number 101 is information for identifying each of a plurality of list images displayed on the panel 50. The list image is an image for receiving execution start commands for various processes. The list character string 103 is information indicating the contents of the character string displayed on the list image. The area coordinate 104 is information indicating an area (list display area) in which each list image is displayed on the panel 50. The coordinate C1 is a coordinate indicating the upper left corner of the rectangular list display area. The coordinate C2 is a coordinate indicating the lower right corner of the rectangular list display area. The display state flag 105 is information indicating whether or not the list image is displayed in the scroll area. The display state flag 105 is “displaying” when at least a part of the list display area defined by the area coordinates 104 is present in the display area of the scroll area, and “non-display” when there is not. Become. The list pressing state flag 106 is information that is “ON” when the designated coordinates are present in the list display area defined by the area coordinates 104 and is “OFF” when the designated coordinates are not present. That is, it is information for identifying whether or not the list image is touched. The reverse display flag 107 is information that is “ON” when the list image is reversely displayed, and is “OFF” when the list image is not reversely displayed. Inverted display is a type of highlighted display, and is an aspect in which characters and background colors are inverted and displayed. The list display width 108 is a dimension of the list image in the x direction. The list display height 109 is a dimension in the y direction of the list image. The execution processing content 110 is information indicating processing associated with each list image. Various types of information stored in the list image table TB1 may be stored in advance by the manufacturer of the multi-function device 10.

  The NVRAM 40 stores a timeout table TB2. FIG. 5 shows an example of the timeout table TB2 in the present embodiment. The time-out table TB2 stores a moving speed range number 201, a moving speed range VR, and a first predetermined time TE. The moving speed range number 201 is information for identifying each moving speed range VR. The movement speed range VR is information that defines the range of the movement start speed TV (dot / sec). The movement start speed TV is a movement speed of the designated coordinates when the designated coordinates start to move. The unit (dot / sec) of the movement start speed TV is the number of dots of pixels of the panel 50 in which the designated coordinates have moved per second. The first predetermined time TE (sec) is the time from when the scroll display of the list image is started until the reverse display is finished. The first predetermined time TE is stored corresponding to each of the moving speed ranges VR. Further, the first predetermined time TE is increased in accordance with the increase in the moving speed range VR.

  The NVRAM 40 stores various parameters. An example of the stored parameter is a moving speed threshold value. The moving speed threshold is a parameter used when determining whether or not a flick operation is input to the coordinate detection unit 51.

  The printing unit 54 is a part that executes printing. The scanning unit 56 is a part that reads a document and converts it into data. The FAX unit 58 is a part that transmits and receives data-converted documents. The network interface 60 is connected to the wired LAN line 4 and is a part that transmits and receives various data.

<Operation of multi-function device 10>
The operation of the multi-function device 10 will be described using the flowcharts of FIGS. The flow in FIGS. 2 to 4 starts when the power of the multi-function device 10 is turned on, and continues to be executed until the power is turned off.

  In S <b> 102, the CPU 14 displays a screen image including a scroll area on the panel 50. FIG. 8 shows a screen display example of the screen image displayed on the panel 50. The screen display example of FIG. 8 is a display example based on the list image table TB1 of FIG. In the screen display example of FIG. 8, the scroll area SA1 is displayed on the panel 50. In the list image table TB1 of FIG. 6, as shown in the region R0, the display state flag 105 of the list number 101 = “4” to “8” is set to “displaying”. Therefore, list images B4 to B8 are displayed in the scroll area SA1 of FIG. In the scroll area SA1, list images B4 to B8 are displayed in a row in the y direction (vertical direction). The scroll area SA1 is an area in which the list image can be scroll-displayed in the upward direction T1 or the downward direction T2 along the vertical direction (y direction) where the list images B4 to B8 are arranged.

  The list image B4 is displayed based on the information in the column of the list number 101 = “4” of the list image table TB1 (FIG. 6). Similarly, each of the list images B5 to B8 is displayed based on information in each column of the list number 101 = “5” to “8”. The list image B4 is an image for accepting a setting change of the paper type (eg, plain paper, glossy paper, etc.) used in the printing unit 54. The list image B5 is an image for accepting a setting change of the paper size (eg, A4 size, B5 size, etc.) used in the printing unit 54. The list image B6 is an image for accepting a setting change of a layout (for example, 2 in 1) when the printing unit 54 performs printing. The list image B7 is an image for accepting a change in setting of the quality of the printing process (eg, high-quality printing, normal printing, etc.) executed by the printing unit 54. The list image B8 is an image for accepting input of various detailed settings. Note that description of other list images is omitted.

  In S104, the CPU 14 resets the press determination flag to “OFF”. Further, the CPU 14 resets the moving flag to “OFF”. In S106, the CPU 14 acquires an event. An event (also referred to as a message) is a signal transmitted to the program when some action (eg, timer timeout, input of designated coordinates to the coordinate detection unit 51, etc.) occurs when the image display program 18 is executed. is there. In S108, the CPU 14 determines whether or not the acquired event is a touch panel operation event for the scroll area. If it is a touch panel operation event (S108: YES), the process proceeds to S130 (FIG. 3).

  In S130, the CPU 14 determines the type of touch panel operation event. There are three types of touch panel operation events: “pressing start”, “designated coordinate movement”, and “separation”. The “pressing start” event is an event acquired when a pressing operation on any list image is started. For example, an event of “pressing start” may be acquired in response to the start of detection of the designated coordinates in the list display area of any list image. The “designated coordinate movement” event is an event that is acquired when the designated coordinate movement in the direction in which the list image can be scrolled (upward direction T1, downward direction T2) is detected. The “separation” event is an event acquired when the indicator is separated from the surface of the panel 50. For example, a “separation” event may be acquired in response to a transition from a state in which designated coordinates are detected to a state in which designated coordinates are not detected.

  When it is determined that the touch panel operation event type is “start pressing” (S130: start pressing), the process proceeds to S132. In S132, the CPU 14 sets the list pressing state flag 106 (list image table TB1) of the specific list image (the list image pressed by the indicator at the start of pressing) to “ON”. Specifically, the pressing start position coordinates exist in the list display area by comparing the indicated coordinates (pressing start position coordinates) where detection has started with the area coordinates 104 of each list image in the list image table TB1. Detect list images. Then, the list pressing state flag 106 of the detected list image is set to “ON”.

  In S <b> 134, the CPU 14 sets the press determination flag stored in the RAM 30 to “ON”. In S138, the CPU 14 issues a time event such that the timeout event occurs after the second predetermined time TS has elapsed. For example, the reverse display start timer may start counting down the second predetermined time TS. Then, the process returns to S106 (FIG. 2).

  On the other hand, if it is determined in S130 that the touch panel operation event type is “instruction coordinate movement” (S130: instruction coordinate movement), the process proceeds to S142. In S <b> 142, the CPU 14 determines whether or not the moving flag stored in the RAM 30 is “ON”. When the moving flag is “ON” (S142: YES), the process proceeds to S152, and when it is not “ON” (S142: NO), the process proceeds to S143. In S143, the CPU 14 sets the moving flag to “ON”. In S <b> 144, the CPU 14 sets the press determination flag stored in the RAM 30 to “OFF”.

  In S146, the CPU 14 calculates the movement start speed TV of the designated coordinates. An example of a method for calculating the movement start speed TV will be described. The CPU 14 uses the coordinate detection unit 51 to detect the designated coordinates at a predetermined detection cycle (eg, every several tens of milliseconds). The movement start speed TV of the designated coordinates is calculated based on the distance between the designated coordinates detected immediately after the pointer starts moving and the designated coordinates detected before the movement of the pointer is started, and the detection cycle. can do. In S148, the CPU 14 refers to the timeout table TB2 (FIG. 5), and acquires the first predetermined time TE corresponding to the movement start speed TV.

  In S149, the CPU 14 issues a fade-out display event. The fade-out display event is an event for displaying the list image so as to gradually return from the reverse display to the normal display. In S150, the CPU 14 issues a time event so that the timeout event occurs after the first predetermined time TE has elapsed. For example, the reverse display end timer may start counting down for the first predetermined time TE.

  In S152, the CPU 14 changes the display state flag 105 according to the movement amount of the designated coordinates. The image in the scroll area is redrawn. Thereby, the scroll display of the list image is performed so as to follow the movement of the designated coordinates.

  In S154, the CPU 14 determines whether or not the specific list image (the pressed list image) is out of the scroll area. The frame-out is a display process in which the list image initially displayed in the scroll area is not displayed in the scroll area by moving to the outside of the scroll area. This determination is based on the fact that at least a part of the list display area of the specific list image (list image corresponding to the list pressing state flag 106 = “ON”) exists in the display area of the scroll area in the list image table TB1. It can be done depending on whether or not. If the frame is not out (S154: NO), the process returns to S106, and if the frame is out (S154: YES), the process proceeds to S156. In S156, the CPU 14 sets the reverse display flag 107 of the specific list image (the list image in which the list pressing state flag 106 is “ON”) in the list image table TB1 to “OFF”. Then, the process returns to S106.

  On the other hand, when it is determined in S130 that the touch panel operation event type is “separation” (S130: separation), the process proceeds to S162 (FIG. 4). In S162, the CPU 14 determines whether or not the press determination flag stored in the RAM 30 is set to “ON”. When the pressing determination flag is “ON” (S162: YES), it is determined that the indicator that has pressed the specific list image is separated from the surface of the panel 50. That is, it is determined that the pressing of the specific list image has ended. Therefore, it progresses to S164. In S164, the CPU 14 sets the reverse display flag 107 of the specific list image (the list image in which the list pressing state flag 106 is “ON”) to “OFF”. In S166, the CPU 14 redraws the image in the scroll area. Thereby, the specific list image is returned to the normal display. In S168, the CPU 14 executes the execution processing content 110 of the specific list image (list pressing state flag 106 = list image corresponding to “ON”). Then, the flow ends.

  On the other hand, if the press determination flag is not “ON” in S162 (S162: NO), the process proceeds to S172. In S172, the CPU 14 determines whether or not a flick operation has been input. For example, when the indicator moves away from the surface of the panel 50, the movement speed of the indicated coordinates is calculated, and when the calculated movement speed is larger than the movement speed threshold stored in the NVRAM 40, a flick operation is input. You may decide that

  In S174, the CPU 14 executes a continuous scroll display corresponding to the flick operation. The continuous scroll display may be realized, for example, by continuously executing the scroll display at a scroll speed corresponding to the moving speed when the indicator is separated from the surface of the panel 50. In this case, a continuous scroll display in which the scroll speed decreases with time may be executed by decelerating the calculated moving speed with time using a speed decay function.

  On the other hand, if it is determined in S108 (FIG. 2) that the acquired event is not a touch panel operation event (S108: NO), the process proceeds to S112. In S112, the CPU 14 determines whether or not a timeout event indicating that the second predetermined time TS has elapsed has occurred. When the time-out event has not occurred (S112: NO), the process proceeds to S118. On the other hand, when a time-out event occurs (S112: YES), it is determined that the second predetermined time TS has elapsed from the time when the specific list image is started to be pressed. Therefore, it progresses to S114.

  In S114, the CPU 14 sets the reverse display flag 107 of the specific list image (list image corresponding to the list pressing state flag 106 = “ON”) 107 to “ON”. In S116, the CPU 14 redraws the image in the scroll area. As a result, the specific list image is displayed in reverse video. Then, the process proceeds to S118.

  In S118, the CPU 14 determines whether or not a fade-out display event (S149) has been issued. If a fade-out display event has been issued (S118: YES), the process proceeds to S119. In S119, the CPU 14 redraws the image in the scroll area so that the specific list image shifts from the reverse display to the normal display at a predetermined rate (eg, 3%). Every time the redrawing process of S119 is repeated at a predetermined cycle, the display is switched from the reverse display to the normal display at a predetermined rate, so that the reverse display gradually changes from the reverse display to the normal display as time passes (the reverse display fades out). A visual effect can be obtained.

  In S120, the CPU 14 determines whether or not a time-out event indicating that the first predetermined time TE has elapsed has occurred. If a time-out event has occurred (S120: YES), it is determined that the first predetermined time TE has elapsed since the start of the scroll display. Therefore, it progresses to S122. In S122, the CPU 14 sets the reverse display flag 107 of the specific list image (list pressing state flag 106 = list image corresponding to “ON”) to “OFF”. In S124, the CPU 14 redraws the image in the scroll area. Thereby, the specific list image is returned to the normal display.

  On the other hand, if a time-out event indicating that the first predetermined time TE has not occurred in S120 (S120: NO), the process proceeds to S128. In S128, the CPU 14 executes the process when there is another process. Since the other processes are general processes, description thereof will be omitted. Then, the process returns to S106.

<Operation example>
An operation example of the multi-function device 10 will be described with reference to FIGS. As an example, a case where the user presses down the list image B5 and then drags the list image B5 in the downward direction T2 of the panel 50 will be described. Further, a case where the movement start speed TV at the start of the drag operation is 250 (dot / sec) will be described.

  The CPU 14 displays a screen image (FIG. 8) on the panel 50 (S102). When the user presses the list image B5 (S130: start pressing), the list pressing state flag 106 of the specific list image (list image B5) is set to “ON” (S132) (FIG. 7, area R1). Further, the countdown of the second predetermined time TS is started (S138).

  When the second predetermined time TS elapses while the user presses down the list image B5 (S112: YES), the reverse display flag 107 of the specific list image (list image B5) is set to “ON” (S114) (FIG. 7). , Region R2). Then, as shown in FIG. 9, the specific list image (list image B5) is displayed in reverse (S116).

  Thereafter, when the user moves the fingertip in the downward direction T2 of the panel 50 while pressing down the list image B5 (S130: designated coordinate movement), the movement of the designated coordinate is started (S142: NO). The speed TV is calculated (S146). The time-out table TB2 (FIG. 5) is referred to, and a first predetermined time TE (1.0 sec) of the moving speed range number 201 = “2” corresponding to the moving start speed TV = 250 (dot / sec) is acquired ( S148). Also, a fade-out display event is issued (S149), and the countdown of the first predetermined time TE is started (S150).

  The display state flag 105 of the list image table TB1 is changed according to the movement amount of the designated coordinates. In the example of the present embodiment, as shown in a region R3 in FIG. 7, the display state flag 105 of the list numbers 101 = “7” and “8” is changed to “non-display”. Further, as shown in a region R4 in FIG. 7, the display state flag 105 of the list numbers 101 = “2” and “3” is changed to “displaying” (S152). Thereby, as shown in the display example of FIG. 10, the scroll display of the downward direction T2 is performed. Due to the scroll display, the list images B7 and B8 are framed out from the lower side of the scroll area SA1. At the same time, the list images B2 and B3 (list images corresponding to the list numbers 101 = “2” and “3” in the list image table TB1) are framed in from the upper side of the scroll area SA1. The frame-in is a process that is displayed on the panel 50 when a list image that was not initially displayed in the scroll area SA1 moves into the scroll area SA1.

  When the execution of scroll display is started, an event of fade-out display is issued (S118: YES), so that the display gradually changes from reverse display to normal display as time passes (S119). Then, when the first predetermined time TE has elapsed from the start of the execution of scroll display (S120: YES), the reverse display flag 107 of the specific list image (list image B5) is set to “ON” (FIG. 7, region R2). ) To “OFF” (S122). Then, as shown in FIG. 11, the specific list image (list image B5) is returned to the normal display. (S124).

<Effect>
The effect of the multi-function device 10 according to the present embodiment will be described. In the multi-function device 10 described in the present specification, in response to the elapse of the first predetermined time TE from the point in time when the execution of the scroll display is started (S150) (S120: YES), the specific list image is displayed in reverse. Can be terminated. Accordingly, it is possible to lengthen the period during which the specific list image is displayed in reverse as compared with the case where the reverse display of the specific list image is ended when the execution of the scroll display is started. Therefore, it is possible to alleviate the visual effect that the pressed list image flickers (inverted display for a very short time), so that it is possible to prevent the user from having a visual discomfort. It becomes possible.

  In the multi-function device 10 described in the present specification, the first predetermined time TE is set to be large in accordance with the increase in the movement start speed TV of the designated coordinates (S148, timeout table TB2). That is, as the movement start speed TV increases, the period during which the specific list image is displayed in reverse can be lengthened. As the movement start speed TV increases, the scroll speed increases and the selection of the list image becomes difficult. Therefore, even if the period during which the specific list image is highlighted is extended, the specific list image is still selected. The risk of misidentifying the user can be reduced. Then, by lengthening the period during which the specific list image is highlighted, it is possible to reduce the visual effect that the pressed list image flickers.

  When the specific list image is out of the scroll area and is no longer displayed on the panel 50 in the reverse display state (S154: YES), the reverse display of the specific list image can be ended (S156). As a result, the specific list image can be framed again in the scroll area in a state where it is not highlighted. Accordingly, since the reverse display of the specific list image can be ended by out-of-frame, it is possible to prevent the user from having a visual effect that the list image flickers.

  In response to the elapse of the second predetermined time TS from when the specific list image is started to be pressed (S112: YES), the specific list image can be displayed in reverse. Therefore, when the execution of scroll display is started before the second predetermined time TS has elapsed since the start of pressing the specific list image, the specific list image is not highlighted. As a result, it is possible to prevent the user from having a visual effect that causes the list image to flicker.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects. A modification is shown below.

<Modification>

  In S124, various modes may be used for ending the reverse display of the specific list image. For example, the specific list image may be ended in a fade-out mode. In this case, in S124, the image in the scroll area may be redrawn so as to shift from the reverse display to the normal display at a predetermined rate (eg, 3%). Thereby, every time the redrawing process of S124 is repeated at a predetermined cycle, the display is switched from the reverse display to the normal display at a predetermined rate, so that a visual effect is obtained in which the display gradually changes from the reverse display to the normal display over time. be able to. Therefore, it is possible to alleviate a visual effect that causes the specific list image to flicker.

  Although the time during which the specific list image is displayed changes according to the movement start speed TV (S148), it is not limited to this form. For example, you may change according to the display area of a specific list image. In this case, for example, the timeout table TB2a shown in FIG. 12 may be stored in the NVRAM 40. The timeout table TB2a stores a display area range number 301, a display area range AR, and a third predetermined time TEa. The display area range number 301 is information for identifying each display area range AR. The display area range AR is information that defines the range of the display area (dot) of the list image. The unit (dot) of the display area of the list image is the number of dots of the pixels of the panel 50. The display area of the list image can be calculated by multiplying the list display width 108 by the list display height 109. The third predetermined time TEa (sec) is the time from when the scroll display of the list image is started until the reverse display is finished. The third predetermined time TEa is stored corresponding to each display area range AR. Further, the third predetermined time TEa is increased in accordance with the increase in the display area range AR.

  In the modified example, in S148, the CPU 14 refers to the timeout table TB2a and acquires the third predetermined time TEa corresponding to the display area range AR. Thereby, in accordance with the elapse of the third predetermined time TEa from the time point when the execution of the scroll display is started (S150) (S120: YES), the reverse display of the specific list image can be ended. As the display area of the specific list image increases, the visual effect that the list image flickers tends to increase. However, according to the modified example, the period for which the specific list image is highlighted can be lengthened as the display area of the specific list image increases, so that the visual effect that the specific list image flickers can be obtained. It can be mitigated.

  In this embodiment, the case where the direction in which the list images are arranged and the direction in which the list images can be scroll-displayed is the y direction (vertical direction), but is not limited to this form. It is also possible to display the list images side by side in the x direction (horizontal direction) or scroll the list images in the x direction.

  The number of list images displayed in the scroll area is not limited to the example of this embodiment. Even if there are three or less or five or more, it is possible to obtain the effect of the technique of the present application. Further, the values of the moving speed range VR, the first predetermined time TE, the display area range AR, and the third predetermined time TEa in the timeout tables TB2 and TB2a are examples, and other values can be used.

  A feature of the technology of the present application is that it relates to a display form of the panel 50. Therefore, the application range of the technology of the present application is not limited to the multi-function device 10, and can be applied to various devices (such as mobile phones and notebook PCs) having a display screen.

  Various types of information stored in the ROM 16 or the NVRAM 40 may be stored in an external storage device. Various kinds of information may be read out from the external storage device and temporarily stored in the RAM 30, and then various kinds of processing may be performed.
