JP 2004-139321 A

  However, according to the technique described in Patent Document 1, for example, when the total amount of information to be displayed is large compared to the amount of information that can be displayed at a time, the slider is moved slightly. However, since a large amount of information moves on the screen in a short time, it will be visually recognized by the user. Therefore, the user can stop the slider at an appropriate position corresponding to the desired information. Have difficulty. As a result, there is a problem that it is difficult for the user to find desired information.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a display device that allows a user to easily find desired information.

  In order to achieve this object, the display device of the present invention uses a predetermined number of pieces of information as a display target among a plurality of pieces of information associated with the display order, and displays the predetermined number of pieces of information as the display target in the display order. Display means for displaying and outputting in an array according to the above, a detecting means for detecting a position where the input medium approaches or contacts, and a target display order corresponding to the position where the input medium detected by the detecting means approaches or contacts The predetermined target to be displayed in the order according to the display order from the target acquisition means to be acquired and the display order of the information being displayed on the display means to the target display order acquired by the target acquisition means Control means for causing the display means to display and output the information in an order according to the display order by sequentially switching the number of information, and the control means includes the display pair.

  The present invention may be configured in various modes such as a display device, a display control device that controls the display device, a display method, a display control program that controls the display device, and a recording medium that records the display control program. it can.

  According to the display device of the first aspect, the display order of the information displayed and output at the beginning of the unit time and the relevant condition are determined on the condition that the predetermined operation is performed after the switching of the information to be displayed is started. The display output in the display means is controlled so that the difference from the display order of the information displayed and output at the end of the unit time is smaller than before performing the predetermined operation. Therefore, for the user, by performing the predetermined operation at an arbitrary time point, it is possible to view each information displayed and output from the predetermined operation to the information on the target display order. There is an effect that desired information can be easily found.

  According to the display device according to claim 2, in addition to the effect of the display device according to claim 1, as the display order of the information displayed on the display means approaches the target display order, the user There is an effect that it can be visually recognized and desired information can be easily found.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an external configuration of a multifunction peripheral device (hereinafter referred to as “MFP (Multi Function Peripheral)”) 1 which is an embodiment of a display device of the present invention.

  The MFP 1 has various functions such as a printer function, a scanner function, a facsimile function, and a copy function, and a horizontally long operation panel 6 is provided on the front upper portion thereof. The operation panel 6 is for operating the MFP 1 and mainly includes an operation key 15, an LCD 16, and a touch panel 17.

  On the display surface of the LCD 16, a touch panel 17 which is a kind of input device is disposed. The touch panel 17 is finely divided (for example, at an interval of 1 mm) as a grid pattern, and the touch panel 17 is an electrode that detects contact of a finger in each of the divided areas (hereinafter referred to as “detection areas”). (Sensor) is provided. In addition, although this embodiment demonstrates this embodiment as what touches the touch panel 17 with a finger | toe, even if it operates with input media other than a finger | toe, such as a pen tip, the same input can be performed on the touch panel 17. FIG.

  Each detection area is assigned an identification number for identifying each detection area individually. The identification number of the detection area at the upper left of the touch panel 17 is (0, 0), and the X direction (touch panel 17 The identification numbers (x, y) are assigned so that the numbers are continuous in the Y direction (vertical direction of the touch panel 17). The identification number increases as it goes to the right and downward of the touch panel 17.

  In the touch panel 17, when finger contact is detected, all the identification numbers (x, y) of the detection areas where the finger contact is detected are specified. The CPU 10 (see FIG. 2) executes each process corresponding to the detection area of the identification number (x, y) detected by the touch panel 17.

  FIG. 1B is a diagram illustrating an example of an operation screen displayed on the LCD 16. When the user selects a desired file (for example, to print) from a plurality of image files stored in the storage medium connected to the MFP 1 or the flash memory 14 (FIG. 2) of the MFP 1, the MFP 1 first selects The display order based on the file creation date and the like is associated with each file. Then, the MFP 1 displays a predetermined number (six in the present embodiment) of the images 30a based on the files associated with the display order (that is, the images 30a associated with the display order) as display targets. The six images 30a are displayed and output on the LCD 16 in such an arrangement that the display order of the six images 30a to be displayed increases toward the right end of the display surface of the LCD 16.

  When the number of files is large and all the images 30a cannot be displayed as a list, the MFP 1 performs a slide display on the LCD 16. The slide display is a display in which a certain number of displayed images 30a are exchanged in accordance with the display order so that the user can visually recognize the images 30a as they move sequentially on the screen. It is to display the file so that it can be viewed. The so-called scroll display in which a part of a predetermined number of images 30a displayed on the screen are replaced one by one, and the switching of all of the predetermined number of images 30a displayed on the screen at a time are also equivalent to the slide display.

  In particular, the MFP 1 is configured such that the user can easily find a desired image 30a from among a large number of images 30a that are slide-displayed on the LCD 16.

  As shown in FIG. 1B, on the display surface of the LCD 16, a title display area 29, an image display area 30, a right scroll key 31, a left scroll key 32, A slide bar 33 and a slider 34 are displayed.

  The title display area 29 is an area where the title 29a and the page number 29b of the operation screen are displayed.

  In the image display area 30, six images 30a to be displayed are displayed. In FIG. 1B, in order to make it easy to understand the display order of the images 30a, the display order is given to the images 30a being displayed. That is, FIG. 1B shows that the images 30a in the display order “1 to 6” are displayed. In the present embodiment, a set of six images 30a that are units displayed at one time on one screen is handled as one page. Then, the total number of files is divided by 6, and the value obtained by raising the remainder is shown as the denominator of the number of pages 29b (9999 in the example shown in FIG. 1B), and the number of pages displayed in the image display area 30 It is shown to the user as a numerator of number 29b (001 in the example shown in FIG. 1B). The creation date of the file that is the basis of the image 30a is added to the image 30a together with the display order so that the user can recognize the desired image 30a from the images 30a displayed in the image display area 30. May be. Further, each image 30a displayed in the image display area 30 may be a thumbnail image of each file.

  In the operation screen shown in FIG. 1B, when the user's finger touches the touch panel 17 in an area overlapping the right scroll key 31, the display in the image display area 30 is displayed as one page being displayed at that time. Switch to the next page. Conversely, when the user's finger touches the touch panel 17 in the area overlapping the left scroll key 32, the display in the image display area 30 is switched from the page currently displayed to the previous page. .

  The horizontal width of the slide bar 33 represents the total number of files, and each position of the slide bar 33 corresponds to the display order. Specifically, the left end position toward the slide bar 33 corresponds to the minimum display order, the right end corresponds to the maximum display order, and the corresponding display order increases toward the right end.

  The slider 34 is an index indicating a detection area corresponding to the display order of the file that is the basis of the image 30 a displayed in the image display area 30. For example, as shown in FIG. 1B, when an image 30a with a display order of 1 to 6 is displayed, the slider 34 moves the slide bar 33 associated with the display order with a display order of 1 to 6. It is drawn in the area.

  The MFP 1 starts slide display on the condition that the touch of the user's finger is continuously detected for a predetermined time or longer (1 second or longer in the present embodiment) in the area overlapping the slide bar 33 on the touch panel 17. . That is, switching of the image 30a to be displayed in the image display area 30 is started. Details will be described later with reference to FIG.

  The electrical configuration of the MFP 1 will be described with reference to FIG. FIG. 2A is a block diagram showing an electrical configuration of the MFP 1. The MFP 1 mainly includes a CPU 10, ROM 11, RAM 12, VRAM 13, flash memory 14, operation keys 15, LCD 16, touch panel 17, scanner 20, printer 21, NCU 23, and modem 24.

  The CPU 10, ROM 11, RAM 12, VRAM 13, and flash memory 14 are connected to each other via a bus line 26. The operation key 15, LCD 16, touch panel 17, scanner 20, printer 21, NCU 23, modem 24, and bus line 26 are connected to each other via an input / output port 27.

  The CPU 10 is connected to the control of each function of the MFP 1 and the input / output port 27 according to fixed values and programs stored in the ROM 11, RAM 12, and flash memory 14, or various signals transmitted / received via the NCU 23. Each part is controlled.

  The ROM 11 is a non-rewritable memory that stores a control program executed by the MFP 1. Each program for executing a display update process shown in the flowchart of FIG. 5 and a slide bar operation acquisition process shown in the flowcharts of FIGS.

  The RAM 12 is a rewritable volatile memory, and the VRAM 13 is a memory for storing bitmap data for one screen displayed on the LCD 16. The CPU 10 periodically reads out bitmap data stored in the VRAM 13 and causes the LCD 16 to draw a screen corresponding to the bitmap data. The flash memory 14 is a rewritable nonvolatile memory, and the data stored in the flash memory 14 is retained even after the MFP 1 is powered off.

  FIGS. 3A to 3D are schematic diagrams for explaining an example of a method for operating the slide bar 33. As shown in FIG. 3A, first, the user brings a finger into contact with one point on the slide bar 33 for 1 second or longer. This operation is hereinafter referred to as a long press operation. In addition, the display order of the images 30a that were being displayed before the long press operation is hereinafter referred to as a starting point display order.

  Each position of the slide bar 33 corresponds to the display order. Therefore, when a long press operation is performed, the MFP 1 acquires the display order corresponding to the position on the slide bar 33 where the long press operation is performed as the target display order.

  Next, as shown in FIG. 3B, the MFP 1 starts slide display for sequentially switching the six images 30a to be displayed in the order according to the display order from the starting point display order to the target display order. . When the target display order is larger than the starting display order, the MFP 1 moves the left side of the images 30a toward the left side so that the display order of the images 30a to be displayed is sequentially increased. Control the display output so that it looks like it goes. On the other hand, when the target display order is smaller than the starting display order, the MFP 1 moves the images 30a to the right side so that the display order of the images 30a to be displayed is sequentially reduced. The display output is controlled so that it looks like it does.

  The MFP 1 controls the display output based on the first movement amount until the user performs a predetermined operation described later after the slide display is started. The slide display based on the first movement amount is hereinafter referred to as a follow-up process.

  Here, the “first movement amount” is a value representing the number of images 30a to be displayed during a unit time (for example, 0.6 seconds). Specifically, the first movement amount represents a difference between the display order of the image 30a displayed at the beginning of the unit time and the display order of the image 30a displayed at the end of the unit time. In this embodiment, it is assumed that the unit time is 0.6 seconds and the initial value of the first movement amount is 30. The first movement amount is 30. For example, when the image 30a having the display order of 1 to 6 is displayed at the first 0.1 second of the unit time, 0. In the sixth second, for example, the image 30a displayed and output in the image display area 30 is replaced at a speed at which the images 30a of 31 to 36 are displayed. That is, the minimum display order (for example, 1) among the six images 30a displayed at the beginning of the unit time, and the minimum display order (for example, 31) among the six images 30a displayed at the end of the unit time. This means that the image 30a is replaced so that the difference between and becomes “30”.

  In MFP 1, CPU 10 periodically reads bitmap data stored in VRAM 13 and draws a screen based on the bitmap data on LCD 16. Therefore, the MFP 1 updates the bitmap data stored in the VRAM 13 at intervals of, for example, 0.1 seconds in order to replace the image 30a with the first movement amount. That is, a process of creating bitmap data corresponding to a screen including the images 30a of the display orders 1 to 6 in the image display area 30 and storing them in the VRAM 13, and a screen including the images 30a of the display orders 7 to 12 in the image display area 30 Processing for creating bitmap data corresponding to the above and storing it in the VRAM 13... Processing for creating bitmap data corresponding to the screen including the images 30 a in the display order 31 to 36 in the image display area 30 and storing them in the VRAM 13. Each process is performed at intervals of 0.1 seconds. In order to express the numerical values simply, the unit time is set to 0.6 seconds and the interval of each process is set to 0.1 seconds. Alternatively, the interval may be shorter than 0.6 seconds. Conversely, longer unit times and longer intervals may be used.

  If a predetermined operation is performed during the execution of such tracking processing, the MFP 1 ends the tracking processing and starts attenuation processing. In the present embodiment, the predetermined operation is an operation in which the user moves his / her finger away from the slide bar 33 to make no contact. This operation is hereinafter referred to as an attenuation instruction operation.

  FIG. 3C is a diagram illustrating an example of the LCD 16 in the attenuation process. During the attenuation process, the MFP 1 controls the display output based on the second movement amount. The “second movement amount” represents the number of images 30a to be displayed during a unit time (for example, 0.6 seconds), similarly to the first movement amount. Specifically, during the attenuation process, the MFP 1 displays the minimum display order among the six images 30a displayed at the beginning of the unit time and the minimum among the six images 30a displayed at the end of the unit time. The image 30a is switched so that the difference in display order becomes the second movement amount.

  Details of the method of calculating the second movement amount will be described later with reference to FIG. 4, but the initial value of the second movement amount is a value smaller than the first movement amount immediately before the predetermined operation is performed. That is, the MFP 1 ends the follow-up process and starts the attenuation process, thereby displaying the display order of the image 30a displayed and output at the beginning of the unit time and the display order of the image 30a displayed and output at the end of the unit time. The display output is controlled so that the difference is smaller than before the attenuation instruction operation is performed. Thereby, the apparent moving speed of the image 30a in the image display area 30 is reduced. In the following description, the control is performed so that the difference between the display order of the image 30a displayed and output at the beginning of the unit time and the display order of the image 30a displayed and output at the end of the unit time is reduced. This is referred to as reducing the apparent moving speed of the image 30a.

  As shown in FIG. 3D, when the user performs a predetermined attenuation stop operation during the execution of the attenuation process, the MFP 1 ends the attenuation process and stops the replacement of the image 30a. The attenuation stop operation in the present embodiment is an operation of bringing a finger into contact with the slide bar 33 again or an operation of bringing a finger into contact with a position other than the right scroll key 31 and the left scroll key 32.

  The slider 34 is displayed at a position corresponding to the display order of the images 30 a displayed in the image display area 30. Therefore, as the display order of the images 30 a displayed in the image display area 30 increases, the position of the slider 34 gradually approaches the position where the long press in the slide bar 33 is performed.

  According to the MFP 1, the user can start the follow-up process with a simple operation of continuing the operation of touching the finger for 1 second or longer. Since the image 30a is replaced at a relatively high speed by the follow-up process while the user keeps touching the finger, the target image 30a can be approached in a short time. Furthermore, the user can end the follow-up process and start the attenuation process by performing a simple attenuation instruction operation at an arbitrary time.

  Therefore, the user predicts the position in the slide bar 33 corresponding to the desired display order, and starts the follow-up process by long pressing the position. Then, when the display order of the image 30a displayed on the LCD 16 approaches the desired display order, an attenuation instruction operation is performed to reduce the apparent moving speed of the image 30a, and the image 30a in the target display order is displayed. Each image 30a displayed and output until now can be viewed carefully. As a result, the desired image 30a can be easily found. Further, when the desired image 30a is found during the attenuation process, the user can stop the slide display in a state where the desired image 30a is displayed and output by performing the above-described attenuation stop operation.

FIG. 4 is a graph showing an example of the relationship between the time and the movement amount (first movement amount / second movement amount) in the slide display, and the horizontal axis indicates the elapsed time t after the finger touches the slide bar 33. the stands, the vertical axis represents V ₂ of the first movement amount V ₁ or the second movement amount. In the follow-up process, the MFP 1 acquires the first movement amount for each predetermined period based on the following equation (1), and controls the display output on the LCD 16 based on the first movement amount. On the other hand, in the attenuation process, the second movement amount is acquired every predetermined period based on the following equation (2), and the display output on the LCD 16 is controlled based on the second movement amount.
First movement amount V ₁ = v ₁₀ −bt (1)
Second movement amount V ₂ = v ₂₀ −ct (2)
However,
t is the elapsed time after the finger contacts the slide bar 33, v ₁₀ , v ₂₀ , b, c are constants v ₁₀ > v ₂₀
b> c

  The first movement amount and the second movement amount calculated based on the above equations (1) and (2) are values that become smaller with the passage of time. Therefore, as the display order of the images 30a displayed on the LCD 16 approaches the target display order, the MFP 1 displays the display order of the image 30a displayed and output at the beginning of the unit time and the image 30a displayed and output at the end of the unit time. The first movement amount and the second movement amount are acquired so as to reduce the difference from the display order of the images, that is, to reduce the apparent movement speed of the image 30a.

  Therefore, in the follow-up process, the user can view each image 30a more carefully as the time after the slide display starts, that is, as the target display order is approached. Therefore, the user starts the attenuation process from an appropriate time point by performing an attenuation instruction operation at an appropriate time point when the image 30a in the display order near the desired display order is displayed while visually checking each image 30a. be able to.

  Furthermore, also in the attenuation process, as the display order of the images 30a to be displayed and output approaches the target display order, the user can visually recognize each image 30a and can easily find a desired image 30a. .

As shown in FIG. 4, first, when the user touches the slider 34 and the long press time exceeds 1 second (time t ₁ ), the MFP 1 starts follow-up control based on the first movement amount.

Then, at time t _2, the attenuation instruction operation is performed, MFP 1 starts the decay process based on the second movement amount. As shown in FIG. 4, since the first movement amount (v ₁₀ −bt ₂ ) calculated at time t ₂ is equal to or greater than the second movement amount (v ₂₀ −ct ₂ ), MFP 1 starts from time t ₂ . The process proceeds to an attenuation process based on the second movement amount calculated by the equation (2). In this way, the amount of movement can be made different before and after the attenuation instruction operation is performed, and the apparent movement speed of the image 30a can be greatly reduced.

Then, at time _{t 4,} the user performs a damping stop operation, MFP 1 stops replacement image 30a.

On the other hand, when the attenuation instruction operation is performed at a time later than the time t ₃ (= (v ₁₀ −v ₂₀ ) / (bc)), based on the time t at the time when the attenuation instruction operation is performed. The calculated first movement amount is less than the second movement amount. Therefore, the MFP 1 continues the tracking process based on the first movement amount even after the attenuation instruction operation is performed. In this way, it is possible to prevent the apparent moving speed of the image 30a from being increased and conversely becoming large despite the user performing the attenuation instruction operation.

  It is assumed that the MFP 1 controls the replacement speed of the image 30a on the LCD 16 by setting a longer time interval for updating the VRAM 13 as the movement amount becomes smaller. For example, in order to perform the follow-up process with the first movement amount (= 30), the VRAM 13 is updated at intervals of, for example, 0.1 seconds. However, since the attenuation instruction operation is performed, the second movement amount (= 15 ), The update of the VRAM 13 is changed to an interval of 0.2 seconds, for example.

  FIG. 5 is a flowchart showing display update processing (including follow-up processing and attenuation processing) executed in MFP 1. This display update process is a process for performing a slide display according to a user's input operation, and is repeatedly executed until the main power supply is turned off after the main power supply of the MFP 1 is turned on.

  First, the CPU 10 draws the operation screen shown in FIG. 1B on the LCD 16 (S504), and then determines whether or not the touch panel 17 is operated by the user (S506). If the determination in S506 is negative (S506: No), the CPU 10 waits for processing.

  On the other hand, if the determination in S506 is affirmative (S506: Yes), then the CPU 10 determines whether or not the slide bar 33 has been operated, that is, the contact state where the finger is in contact with the detection area of the touch panel 17. Then, the contact area is detected, and it is determined whether or not the contact area is the display position of the slide bar 33 (S508).

  If the determination in S508 is affirmative (S508: Yes), the CPU 10 executes a slide bar operation acquisition process (S510) described later with reference to FIG. 6, and returns to S506. On the other hand, if the determination in S508 is negative (S508: No), the CPU 10 executes other processing according to the user's operation other than the slide bar 33 (S512), and returns to S506. For example, when the left scroll key 32 is operated, in S512, a process of replacing the image 30a displayed in the image display area 30 with the image 30a of the previous page is performed.

  FIG. 6 is a flowchart showing the slide bar operation acquisition process (S510). This slide bar operation acquisition process (S510) is a process of replacing the image 30a displayed in the image display area 30 based on the operation performed on the slide bar 33 by the user.

  First, the CPU 10 detects the position where the finger touches the slide bar 33 (S604). Then, it is determined whether or not the finger is stopped on the slide bar 33 for 1 second or longer (S606). If the determination in S606 is negative (S606: No), the process returns to S604 and is repeated.

  On the other hand, if the determination in S606 is affirmative (S606: Yes), the CPU 10 acquires a target display order corresponding to the detected contact position (S607). Next, the CPU 10 determines whether or not the total number of files to be selected (that is, the number of images 30a to be displayed on the LCD 16) is equal to or greater than the user set value (S608). Note that the user setting value is set by the user and stored in advance in the flash memory 14, for example.

  When the determination in S608 is negative (S608: No), the CPU 10 moves the slider 34 at a predetermined constant speed (S610). That is, the display position of the slider 34 on the slide bar 33 is changed by a certain distance. Then, the CPU 10 replaces the image 30a displayed on the screen according to the position of the moved slider 34 (S612). That is, when the number of files to be selected is not so large and the desired image 30a can be easily found, the follow-up processing and attenuation processing described above are not performed, and the apparent moving speed of the image 30a is constant. In this manner, normal slide display for replacing the image 30a in the image display area 30 is performed.

  In the determination of S608, it is only necessary to determine whether the number of files is so large that it is difficult to select a file to be selected from all files. For example, the images 30a based on all files are sequentially displayed as images. You may comprise so that it may be judged whether the number of pages required when displaying on the display area 30 is more than a threshold value.

  Next, the CPU 10 determines whether or not the finger has been removed from the slide bar 33 (S614). If the determination in S614 is affirmative (S614: Yes), the CPU 10 stops the replacement of the image 30a, that is, The slide display is stopped, and the process returns to S506 to repeat the process.

  On the other hand, if the determination in S614 is negative (S614: No), the CPU 10 next determines whether or not the slider 34 has reached the finger position on the slide bar 33 (S616). If the determination in S616 is negative (S616: No), the CPU 10 returns to S610 and repeats the process. If the determination in S616 is affirmative (S616: Yes), the CPU 10 stops replacing the image 30a, returns to S506, and repeats the process.

  Next, a case where the determination in S608 is affirmed will be described. If the determination in S608 is affirmative (S608: Yes), the CPU 10 acquires the first movement amount based on the above equation (1) (S618).

  Next, the CPU 10 executes a follow-up process based on the acquired first movement amount (S620). Specifically, as described above, the slide display is performed by updating the bitmap data in the VRAM 13 at time intervals determined based on the first movement amount. Then, the display position of the slider 34 is changed according to the display order of the image 30a being displayed (S622).

  Next, the CPU 10 determines whether or not the finger is released from the slide bar 33 (S624). If the determination in S624 is negative (S624: No), then the CPU 10 determines whether or not the slider 34 has reached the finger position on the slide bar 33 (S626). If the determination in S626 is negative (S626: No), the CPU 10 returns to S618 and repeats the process. That is, the first movement amount is acquired every predetermined period, and the follow-up process based on the newly acquired first movement amount is continued.

On the other hand, if the determination in S624 is positive (S624: Yes), CPU 10 is the elapsed time t after the contact fingers slide bar 33 _is less than _{(v 10 -v 20) / (} b-c) It is determined whether or not there is (S628). That is, the first movement amount V ₁ (= v ₁₀ −bt) calculated based on the elapsed time t after the finger touches the slide bar 33 is calculated based on the second movement amount calculated based on the same time t. It is determined whether or not it is larger than V ₂ (= v ₂₀ -ct).

  If the determination in S628 is affirmative (S628: Yes), the CPU 10 proceeds to the process shown in FIG. 7 and starts the attenuation process. On the other hand, if the determination in S628 is negative (S628: No), the CPU 10 returns to S618 and repeats the process. That is, the follow-up process based on the first movement amount is continued. If the user performs a predetermined attenuation stop process while the follow-up process is continued after the determination in S628 is denied, the CPU 10 stops replacing the image 30a and returns to S506. The illustration and detailed description are omitted.

  FIG. 7 is a flowchart showing a continuation of the slide bar operation acquisition process (S510) shown in FIG. The CPU 10 executes the attenuation process by the process according to the flowchart shown in FIG.

  First, the CPU 10 acquires the second movement amount based on the above equation (2) (S702). Next, the CPU 10 executes an attenuation process for replacing the image 30a displayed in the image display area 30 with the second movement amount (S704). Specifically, as described above, the bitmap data in the VRAM 13 is updated at a time interval determined based on the second movement amount.

  Next, the CPU 10 changes the position of the slider 34 in accordance with the display order of the displayed image 30a (S706).

  Next, the CPU 10 determines whether or not an attenuation stop operation has been performed (S708). When the determination of S708 is affirmed (S708: Yes), for example, when an operation of bringing the finger into contact with the slide bar 33 again is performed, the CPU 10 stops the replacement of the image 30a, that is, stops the attenuation process. The process returns to S506. For the user, when a desired image 30a is found, the attenuation process can be stopped in a desired display order by performing a simple attenuation stop operation, and the operability is good.

  On the other hand, if the determination in S708 is negative (S708: No), the CPU 10 has reached the position where the long press operation has been performed on the slide bar 33 at the start of the slide bar operation acquisition process (S510). It is determined whether or not (S710). If the determination in S710 is negative (S710: No), the CPU 10 returns to S702 and repeats the process. That is, the second movement amount is acquired every predetermined period, and the attenuation process is continued based on the newly acquired second movement amount. On the other hand, if the determination in S710 is affirmative (S710: Yes), that is, if the display order of the image 30a has reached the target display order, the CPU 10 stops replacing the image 30a, returns to S506, and repeats the processing. .

  In the above-described embodiment, the image 30a based on the file corresponds to an example of information associated with the display order, the LCD 16 corresponds to an example of a display unit, the finger corresponds to an example of an input medium, and the touch panel 17 corresponds to an example of a detection unit. The CPU 10 that executes S607 corresponds to an example of a target acquisition unit, the CPU 10 that executes S510 corresponds to an example of a control unit, the attenuation instruction operation corresponds to an example of a predetermined operation, and (1) The expression 10 corresponds to the first relationship, the CPU 10 that executes S618 corresponds to an example of the first movement amount acquisition unit, the expression (2) corresponds to the second relationship, and the CPU 10 that executes S702 performs the second movement. This corresponds to an example of a quantity acquisition unit, and the CPU 10 that executes S628 corresponds to an example of a determination unit.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above-described embodiment, the attenuation instruction operation has been described by taking, as an example, an operation in which a user moves an input medium such as a finger away from the touch panel 17 and makes no contact. However, the specific example of the attenuation instruction operation (predetermined operation) for starting the attenuation process in the MFP 1 is not limited to this. For example, an operation of double-clicking one point in the slide bar 33 may be used as the attenuation instruction operation. good. Further, an operation of touching two points on the touch panel 17 by touching an input medium such as a finger on another point on the touch panel 17 while continuing to press the input medium on the touch panel 17 as an attenuation instruction operation. Also good.

  In the above embodiment, the slide display is started on the condition that the long press operation is performed. However, a specific example of the operation for starting the slide display in the MFP 1 is not limited to this. For example, an operation of double-clicking one point in the slide bar 33 may be an operation for starting slide display. Further, an operation of touching two points on the touch panel 17 may be an operation for starting slide display.

  In the above-described embodiment, the input medium is described as being non-contact with the touch panel 17 during the attenuation process. However, while the input medium continues to be touched at any position on the touch panel 17 after the attenuation process is started. The display device may be configured to continue execution of the attenuation process. In the touch panel 17, the number of detection areas (number of electrodes) in which contact with the input medium is detected represents the size of the contact area. Therefore, the display device may be configured to change the second movement amount on the touch panel 17 based on the number of detection areas in which the contact of the input medium is detected during the attenuation process. For example, the second movement amount is increased when the contact area of the input medium is increased, and the second movement amount is decreased when the contact area of the input medium is decreased. In this way, it is possible for the user to increase the apparent moving speed of the image 30a by increasing the finger contact area on the touch panel 17 during the attenuation process. On the other hand, the apparent moving speed of the image 30a can be reduced by slightly lifting the finger touching the touch panel 17 and reducing the contact area. As a result, the user can adjust the apparent moving speed of the image 30a with a more intuitive operation.

  Moreover, in the said embodiment, although the touch panel 17 which detects a user's finger | toe contact is used, you may use the touch panel which detects the approach of a user's finger | toe. Specifically, when the fingertip and the touch panel approach (or come into contact), the projection-type static utilizing the fact that the finger and the touch panel are electrostatically coupled and the capacitance between the finger and the touch panel changes. A capacitive touch panel may be used. Further, a touch panel that detects the approach (or contact) of a finger with infrared rays or an electric field may be used.

  In the above embodiment, the image 30a is arranged in the image display area 30 of the LCD 16 in the ascending order of the display order. However, the present invention is also applicable to the case where the images 30a are displayed in the descending order of the display order. Is applicable.

  In the above-described embodiment, the image 30a based on the file is an example of information associated with the display order. However, even if the information is other than the image, the information is an information associated with the display order. For example, it may be a character string. For example, instead of the image display area 30, an area in which a plurality of information composed of character strings is displayed as a list and each information is displayed in a list in the order of display according to a user operation, the present invention is also applicable. Is applicable.

  Further, the proportional constants b and c in the above equations (1) and (2) may be fixed values determined in advance, or values that can be appropriately changed by the user. Further, the first movement amount and the second movement amount calculated by the above expressions (1) and (2) are calculated based on the elapsed time t after the finger contacts the slide bar 33. However, for example, it may be calculated based on the remaining distance L until the slider 34 reaches the position where the finger contacts the slide bar 33. In addition, in the above equations (1) and (2), the first movement amount and the second movement amount are calculated by a linear function with the time t as a variable. You may comprise so that a 1st movement amount and a 2nd movement amount may be calculated with a function (n is an integer greater than or equal to 2). Moreover, you may comprise so that a user can select what function calculates the 1st movement amount and the 2nd movement amount.

  In the above embodiment, the display output is controlled so that the apparent moving speed of the image 30a is gradually reduced in the follow-up process. Instead, the apparent image 30a is displayed during the follow-up process. Display device so that the upper moving speed (that is, the difference between the display order of information displayed and output at the beginning of the unit time and the display order of information displayed and output at the end of the unit time) is always constant May be configured.

  Further, in the above-described embodiment, “display means so as to reduce the difference between the display order of the target display information displayed at the beginning of the unit time and the display order of the target display information displayed at the end of the unit time”. As a specific means for “controlling”, the example in which the time interval for updating the VRAM 13 is changed based on the first movement amount or the second movement amount has been described. However, various other specific means are conceivable. Hereinafter, a first modification will be described. For example, in a configuration in which six images 30a are displayed on one screen, when the unit time is 0.6 seconds and the first movement amount is 24, in the first modification, the images in the display order 1 to 6 are displayed. After performing the process of creating bitmap data for the display target 30a and storing it in the VRAM 13, the process of creating the bitmap data for the image 30a in the display order 13 to 18 and storing it in the VRAM 13 is performed next. Next, the VRAM 13 may be updated every 0.2 seconds by performing a process of creating bitmap data for the images 30a in the display order 25 to 30 as display targets and storing them in the VRAM 13. The “difference between the display order of information displayed and output at the beginning of a unit time and the display order of information displayed at the end of the unit time” herein refers to information displayed at the beginning of a unit time ( The difference between the minimum value of the display order of the image 30a) and the minimum value of the display information of the information displayed at the end of the unit time, or the display order of the information displayed at the beginning of the unit time It is a value that can be obtained as the difference between the maximum value and the maximum value of the information displayed at the end of the unit time. In the process of displaying each information up to the target display order in the order according to the display information as in this modification, there is display order information that is not displayed on the LCD 16 (that is, information that is skipped). May be.

  When the first modified example is adopted in the display device, by reducing the number of images 30a that are not displayed, “the display order of information displayed and output at the beginning of unit time and the display output at the end of the unit time” are performed. The display output may be controlled so that the “difference from the information display order” becomes small.

  In addition, the MFP 1 starts the memory in which bitmap data for three pages (for example, bitmap information corresponding to an image including 18 pieces of information when six pieces of information are displayed at a time) is developed. A configuration may be adopted in which the address is accessed, the image indicated by the bitmap data for one page from the accessed address is displayed, and the address to be accessed is changed for each predetermined line so that the image is slid. . Hereinafter, this example will be described as a second modification. In the case of adopting the second modified example, processing for displaying an image so that the difference in display order becomes the first movement amount (for example, 30) per unit time (for example, 0.6 seconds) is, for example, as follows. . First, bitmap data for three pages is created based on the information of the display orders 1 to 6, 7 to 12, and 13 to 18 and stored in the memory. Next, the screen is displayed by accessing the top address of the memory, and the screen is displayed while gradually shifting the address to be accessed to the subsequent address. After displaying bitmap data for three pages stored in the memory in 0.3 seconds, next, bitmap data for one page based on the display order 19 to 24 is created, and the top address of the memory is used. Remember. That is, the bitmap data based on the information of the display orders 19 to 24 is overwritten on the area where the bitmap data based on the information of the display orders 1 to 6 is stored. When 0.1 second elapses, bitmap data for one page based on the information of the display order 25 to 30 is created and stored from the address after the memory size of the bitmap data for one page from the top address of the memory. Further, when 0.1 second elapses, one page of bitmap data is created based on the information of the display order 31 to 36, and stored from the address after the memory size of the bitmap data of two pages from the top address of the memory. . As described above, the MFP 1 may have a memory for storing bitmap data for a plurality of pages, and the control unit may store the data in the memory while shifting the memory address. In this case, the difference between the display order of information displayed at the beginning of the unit time (0.6 seconds) (for example, 1 to 30) and the display order of information displayed at the end of the unit time (for example, 31 to 36). Becomes “30”.

  When the second modified example is adopted in the display device, the difference between the display order of the information displayed and output at the beginning of the unit time and the display order of the information displayed and output at the end of the unit time is reduced. In order to control the display output, for example, the time interval for updating the bitmap data may be increased.
