Abstract

PROBLEM TO BE SOLVED: To provide a display controller and an information processor capable of reducing the time and labor of scrolling by utilizing an index even when a display screen is small.SOLUTION: While a list in which a plurality of selection items are registered is displayed in a list display area within a screen, when a scrolling operation to the list display area is received, the indexes of groups for which the selection items registered in the list are divided into plural are displayed in an area where information not to be used during scroll display has been displayed. When an operation of selecting a group from the indexes is received, the selection items corresponding to the selected group are displayed in the list display area.

Description

  The present invention relates to a display control apparatus and an information processing apparatus that control scroll display.

  When all the items registered in the list cannot be displayed at once in the display area, the display range is usually moved by scrolling. However, if the display area is small and the number of items registered in the list is large, it takes a lot of time and effort to scroll to find the target item.

  Therefore, for example, in the search of the address book, index data representing a group of address data is created, and when the address data is displayed, the index is also displayed. When the user selects the index, it belongs to the corresponding group. A technique for displaying address data has been proposed (see Patent Document 1).

  The RAM 13 is used as a work memory for temporarily storing various data when the CPU 11 executes processing based on a program, an image memory for storing image data, and the like.

  The image reading unit 14 functions to optically read a document and acquire image data. The image reading unit 14 sequentially, for example, a light source that irradiates light on a document, a line image sensor that receives the reflected light and reads the document for one line in the width direction, and sequentially reads the reading position in line units in the length direction of the document. An optical path composed of a moving unit for moving, a lens, a mirror, and the like for guiding reflected light from the document to the line image sensor to form an image, and a conversion unit for converting an analog image signal output from the line image sensor into digital image data And so on.

  The printer unit 15 functions to form an image corresponding to the image data on a recording sheet. Here, it has a recording paper transport device, a photosensitive drum, a charging device, a laser unit, a developing device, a transfer separation device, a cleaning device, and a fixing device, and forms an image by an electrophotographic process. It is configured as a so-called laser printer. Other methods may be used for image formation.

  The image processing unit 16 performs processing such as image enlargement / reduction, rotation, rasterization processing for converting print data into image data, image data compression / decompression processing, and the like.

  The nonvolatile memory 17 is a memory (flash memory) whose stored contents are not destroyed even when the power is turned off, and is used for storing various setting information. The nonvolatile memory 17 stores address book data and job history data as a list.

  The automatic document feeder (ADF) 18 feeds the document set on the document table one by one from the uppermost one in order, passes it through the reading position of the image reading section 14 and discharges it to a predetermined discharge position. It performs the function of paper.

  The facsimile communication unit 19 performs a function of transmitting / receiving image data to / from an external device having a facsimile function through a public line.

  The network communication unit 21 performs a function of communicating data with a terminal device or other external devices through a network such as a LAN (Local Area Network).

  The operation display unit 30 includes a display unit 31 and an operation unit 32. Among these, the operation unit 32 includes a switch unit 33 such as a start button and a touch panel unit 34. The display unit 31 is composed of a liquid crystal display (LCD) and the like, and has a function of displaying various operation screens, setting screens, and the like.

  The touch panel unit 34 is provided on the screen of the display unit 31. The touch panel unit 34 detects a coordinate position where the screen is pressed with a touch pen or a finger, a flick operation, a drag operation, and an operation on a scroll bar.

  In the image processing apparatus 10, a list of addresses (address list) registered in the address book is displayed in a list display area in the screen of the display unit 31, and an operation for selecting an item registered in the list is performed by the user. Has the function to receive. For example, a destination selection operation is received from the address list in a job submission operation for facsimile transmission or e-mail transmission, or a job selection operation to be re-executed is received from a job list in which a history of jobs executed in the past is registered. It has a function such as.

  When the image processing apparatus 10 receives a scroll operation for the list display area displaying the list, the image processing apparatus 10 starts scroll display of the list in the list display area and groups the items registered in the list into a plurality of groups. Are displayed in the index display area. The index display area is set to an area where information related to functions that are not used during scroll display of the list (information not related to item selection from the list) was displayed. When a selection operation for any of the displayed indexes is received from the user, items belonging to the group corresponding to the selected index are displayed in the list display area.

  The scroll operation accepted by the image processing apparatus 10 includes a flick operation and a drag operation. The flicking operation is an operation for causing the finger to bounce after touching the screen with a finger or the like. When the flick operation is received on the touch panel unit 34, the CPU 11 detects the direction and speed of the jumping motion (speed when the finger is released). The scroll display is performed according to the detected direction and speed. The drag operation is an operation of sliding a finger while touching the screen with a finger or the like. When a drag operation is received on the touch panel unit 34, the CPU 11 detects the direction and distance in which the finger is slid while being touched. When a drag operation is received, the display is scrolled by the distance dragged in the dragged direction. In addition, in the case of a configuration in which a scroll bar is displayed, a scroll bar moving operation may be accepted as a scroll operation.

  Next, an operation for selecting an item from the list will be described in detail by way of an example in which a destination is selected from the address list.

  FIG. 2 shows an example of the address list selection screen 40 displayed on the display unit 31. The address list selection screen 40 is provided with a horizontally-long rectangular list display area 42 having a height of about 80% of this screen and a width of about 70% of this screen, approaching the lower left corner of the screen. It is. In FIG. 2, the list display area 42 is surrounded by a broken line.

  Above the list display area 42, a tab display field 43 in which tabs 43a to 43c for switching the destination setting method are displayed. FIG. 2 shows a state in which the tab 43c for selecting a destination from the address book is selected. At the top of the address list selection screen 40 (above the tab display field 43), a title field 41 for displaying the title of this screen is provided. On the right side of the list display area 42, an array selection button 44 for switching the arrangement method of items in the list display area 42, a selection button 45 for selecting the type of address displayed in the list display area 42, a specific A selection button 46 for shifting to a screen for searching for an address using a character string or a keyword and a selection button 47 for shifting to a screen for registering a new destination in the address book are arranged. These buttons 44 to 47 displayed on the right side of the list display area 42 are information relating to functions that are not used while scrolling the list displayed in the list display area 42 (referred to as unrelated information). .

  When a scroll operation is performed on the list display area 42 on the address list selection screen 40 in FIG. 2, the address list index is displayed on a part of the address list selection screen 40. The index is information serving as a heading for each group in which destinations (items) registered in the address list are grouped according to a predetermined standard. The index is based on grouping criteria. For example, if the destination name is expressed in alphabets and is grouped by the initials, “A”, “B”, “C”... For example, when the destinations are grouped according to criteria such as “friend”, “family”, “work relationship”, “shop”, “other”, etc., the name of each group (“friend”, “ Family "," Work "," Store "," Other ", etc.) are displayed as an index. The grouping standard and the name of each group can be arbitrarily changed by the user.

  FIG. 3 shows an example of the address list selection screen 40 when index display is started. In this example, in order to make the list display area 42 as large as possible, the list display area 42 is vertically expanded during scroll display. In other words, the list display area 42 is expanded using an area or a blank area in which information related to functions that are not used during scroll display or information that does not require reference is displayed. In the address list selection screen 40 of FIG. 3, the tab display column 43 and the title column 41 are not necessary during the scroll display. Therefore, the height of the list display region 42 is utilized by using these regions and the margin region. Is extended over the entire height of the address list selection screen 40.

  In addition, an index display area 50 is secured in an area where information related to functions that are not used is displayed during scroll display, and an index 51 is displayed in the index display area 50. In this example, the area where the unrelated information (buttons 44 to 47) is displayed and the area where the title column 41 and the tab display column 43 exist are used. A belt-like index display area 50 is ensured throughout.

  In the index display area 50, indexes 51 such as “A”, “B”, “C”... Are displayed. Each index 51 is a selection button. Of the indexes 51 displayed in the index display area 50, the index 51 representing the group to which the destination belongs displayed at the top (top row) of the list display area 42 is displayed in a display mode different from the other indexes 51. The In this example, the color of the index 51a corresponding to the group “A” is displayed in a different color from the other indexes 51b, 51c.

  Note that the indexes 51 of all the groups to which the destination displayed in the list display area 42 belongs may be displayed differently from the other indexes. In the case of the example of FIG. 3, since the destinations of the groups “A”, “B”, and “C” are displayed in the list display area 42, the index 51a of “A”, the index 51b of “B”, and “ The “C” index 51 c may be displayed in a display mode (different color) different from that of the other indexes 51.

  Note that it is also possible to perform a scroll operation on the index display area 50. When the CPU 11 receives a scroll operation for the index display area 50 from the user when all the indexes 51 cannot be displayed in the index display area 50, the CPU 11 scrolls the index 51 in the index display area 50 and displays the index 51 in the index display area 50. The range of is to be changed. In the example of FIG. 3, the indexes after “G” can be displayed by scrolling.

  As shown in FIG. 3, an OK button 52 and a cancel button 53 are further displayed on the address list selection screen 40 after the start of scroll display. However, when the destination is not selected, the OK button 52 cannot be selected. In the figure, non-selectable buttons are indicated by broken lines. Note that a non-selectable button may be hidden. The OK button 52 or the OK button 52 and the cancel button 53 are displayed only when two or more destinations (items) can be selected from the list. When only one item can be selected, the OK button 52 or the OK button is displayed. 52 and the cancel button 53 may be omitted.

  FIG. 4 shows an example of the address list selection screen 40 when one item (item 61 in this example) is selected on the address list selection screen 40 of FIG. The selected item 61 is changed so that its display form is distinguishable from the non-selected item. When any item is selected, the OK button 52 is changed to be selectable.

  FIG. 5 shows an example of the address list selection screen 40 when the “C” index 51c is selected on the address list selection screen 40 of FIG. When the “C” index 51 c is selected, destinations belonging to the “C” group are displayed in the list display area 42. In this example, the line including the destination “C1” (item 62) closest to the top of the list in the “C” group is displayed so as to be positioned at the top (uppermost line) of the list display area 42.

  FIG. 6 shows a flow of operations performed by the CPU 11 (display control device) of the image processing apparatus 10 when a scroll operation is performed on the list display area 42 from the user on the address list selection screen 40 of FIG. When the CPU 11 detects a scroll operation on the list display area 42 via the touch panel unit 34, the CPU 11 displays the index of the address list displayed in the list display area 42 (see step S101, FIG. 3).

  Next, scroll display operation determination processing for determining details of the scroll display operation in the list display area 42 according to the content of the scroll operation (for example, the direction and speed of the flick operation) is performed (step S102). In the scroll display operation determination process, the scroll direction, scroll speed, scroll unit (scroll mode), which will be described later, and the like are determined. Then, according to the determined scroll display operation, the address list is scroll-displayed in the list display area 42 (step S103).

  If no user operation is detected during the scroll display (step S104; No), the process returns to step S102, and the scroll display operation is recalculated so as to reduce the scroll speed using the elapsed time as a parameter (step S102). S102). The “scroll display” may include a state where the scrolling is stopped as a result of the deceleration, and is not limited to a state where the scrolling is actually performed.

  If a scroll operation is received again from the user during the scroll display (step S104; Yes, S105: scroll), the process returns to step S102 and recalculates the scroll display operation (step S102).

  When an operation for selecting any index is received from the user during scroll display (step S104; Yes, S105; select index), the first destination (item) of the group corresponding to the selected index is listed. The display is changed so as to come to the top (top row) of the display area 42 (step S106, see FIG. 5). Then, it returns to step S102 and recalculates the scroll display operation (step S102). In addition, when the process of step S106 is performed, you may make it stop scrolling once.

  When a destination (item) selection operation or an OK button 52 or cancel button 53 operation is received from the user during scroll display (step S104; Yes, S105; key press), the operation is the destination (item). In the case of an operation indicating the end of selection (step S107; Yes), the index display is turned off (step S109), and the scroll display is ended (END).

  The operation indicating the end of the item selection includes an operation of the OK button 52 or the cancel button 53. That is, when the user receives an operation of the OK button 52 or the cancel button 53 during the scroll display (step S105; key press, S107; Yes), the index display is turned off (step S109), and the scroll display is terminated.

  When the number of items that can be selected from the list (the number of selectable items) is N, the selection operation for the Nth item is treated as an operation indicating the end of item selection. For example, when N is 1, when the selection operation of the first destination (item) is received (step S105; key press, S107; Yes), the index display is turned off (step S109), and the scroll display is terminated.

  When the number of selectable items N is 2 or more and the number of destinations selected by the current selection operation is less than N, that is, when the current destination selection operation is not an item selection end operation (Step S107; No), the display form (for example, color) of the selected destination (item) is changed to a display form different from the non-selected item (see Step S108, FIG. 4). Then, it returns to step S102 and recalculates the scroll display operation (step S102).

  The number of selectable items is determined according to the specifications of the image processing apparatus 10 or is arbitrarily set by an administrator or the like. In this example, when the number of selectable items is 1, as soon as any destination is selected, the destination is registered (for example, registered as a scan to email destination). On the other hand, if the number of selectable items is 2 or more, even if a destination is selected, the selected state (reversal etc.) is not entered and only registered, and when the OK button 52 is pressed after selecting one or a plurality of destinations, The destination selected at that time is registered as the transmission destination.

  FIG. 7 is a flowchart showing details of step S102 (scroll display operation determination processing) in FIG. If there is a new scroll operation (step S201; Yes), it is determined whether the scroll operation is performed in the list display area 42 or the index display area 50 (step S202). If the scroll operation is performed on the list display area 42 (step S202; No), the process proceeds to step S204. In the case of a scroll operation on the index display area 50 (step S202; Yes), a value obtained by adding a predetermined specified value to the speed of the scroll operation by the user is set as the speed of the scroll operation (step S203), and the process proceeds to step S204.

  In step S204, the scroll speed (speed when scrolling the display) is calculated from the speed of the scroll operation (step S204). For example, a speed obtained by multiplying the speed of the scroll operation by a predetermined coefficient α so as to be within a predetermined maximum scroll speed and minimum speed is obtained as the scroll speed. Note that the specified value to be added in step S203 is set so that a value obtained by multiplying the specified value by the coefficient α becomes a predetermined boundary speed.

  If the scroll speed obtained in step S204 is equal to or higher than the predetermined boundary speed (step S205; Yes), the scroll unit is set to the large category (step S206), and the process proceeds to step S212. When the scroll operation is performed in the index display area 50, the specified value is added to the scroll operation speed, so the scroll speed obtained in step S204 is equal to or higher than the boundary speed, and the scroll unit is always set to the large category. The

  When the scroll unit is set to the large category, scroll display is performed in a thinning mode for thinning out items in the list. For example, even-numbered items such as first, third, fifth, seventh, etc. are thinned out, and scroll display is performed so that only odd-numbered items are continuously displayed. The thinning-out amount is not limited to the above, and two skipping, three skipping, etc. may be used, and it may be arbitrarily settable.

  If the scroll speed obtained in step S204 is less than the predetermined boundary speed (step S205; No), the scroll unit is set to the small category (step S207), and the process proceeds to step S212. When the scroll unit is set to the small category, scroll display is performed in the normal mode in which items in the list are not thinned out.

  In step S212, details of the scroll display operation are determined. That is, the scroll unit, scroll speed, and scroll direction are determined. If the scroll unit is the small category, the scroll speed obtained in step S204 is determined as the scroll speed as it is. When the scroll unit is a large category, the scroll speed obtained in step S204 is converted to a speed reduced according to the thinning amount. For example, when skipping by one, the scroll speed determined in step S204 is set to the scroll speed that is halved, and when skipping by skipping two, the scroll speed determined in step S204 is set. The scroll speed is set to a speed reduced to one third. The calculation for converting to the scroll speed in the large category is not limited to these.

  If there is no new scroll operation (step S201; No), it is determined whether the current scroll unit is the large category or the small category (step S208). If it is a small category (step S208; small), the process proceeds to step S211. In the case of the large category (step S208; large), the current scroll speed is converted into the scroll speed for the small category. That is, in step S212, the inverse operation of the operation in which the speed is reduced in accordance with the thinning amount is performed to convert the scroll speed in the large category into the scroll speed in the small category (normal mode). For example, when skipping by one, the current scrolling speed is doubled, and when skipping by two, the current scrolling speed is tripled.

  In this way, it is checked whether or not the scroll speed converted into the speed in the small category is equal to or higher than the boundary speed (step S209). If it is less than the boundary speed (step S209; No), the scroll unit is changed to the small category (step S210), and the process proceeds to step S211.

  In step S211, scroll speed reduction processing is performed. For example, the current scroll speed is decelerated at a constant deceleration rate. Here, in the case of the large category, deceleration processing is performed for the scroll speed converted to the small category. After performing the deceleration process, the process proceeds to step S212, the scroll display operation is determined, and this process ends.

  As described above, in the image processing apparatus 10, after a list is displayed in the list display area 42, an index of the list is displayed when a scroll operation on the list is detected, and the index display area 50 is not used during scroll display. Since the information related to the function is displayed in the area where the information is displayed, even when the display screen is small, the index can be displayed to reduce the scrolling effort.

  That is, since the user performs a scroll operation when the target item does not exist among the items displayed in the list display area 42, if the index is displayed when the scroll operation is detected, the index is displayed from the beginning when the list is displayed. The purpose of the index is achieved without displaying. In addition, since the index is deleted when the item selection operation is completed, the display of the index does not hinder the display of information other than the item selection.

  Further, since the index of the group to which the item displayed in the list display area 42 belongs is displayed in a display form (for example, different color) different from the index of the other group, the user can select which group item is in the list display area 42. Can be easily recognized. Thereby, for example, the user can easily and quickly determine whether or not the display range of the list should be changed by selecting an index.

  When the scroll operation speed is equal to or higher than the specified value or when the scroll operation is received on the index display area 50, the scroll unit is displayed in the list display area 42 because the scroll unit is displayed in the thinning mode with a large category. The range on the list can be moved on the list (the list before thinning) at a speed faster than the actual scrolling speed. For example, if the scroll unit is a large category and the skipping amount is skipped by 2, the item display range moves on the list (the list before thinning) at a speed three times the apparent scrolling speed, so scroll display The list can be substantially scrolled at a high speed while ensuring the visibility of the displayed items.

  When receiving a scroll operation on the index display area 50, the index displayed in the index display area 50 may be scroll-displayed, and the display content of the list display area 42 may be scrolled in accordance with the scroll. In this case, scroll display in the list display area 42 is performed using the group indicated by the index as the scroll unit of the large category. For example, the state in which the item “A” group is arranged at the top part of the list display area 42 is statically displayed for a short time, and then the state in which the item “B” group is arranged at the top part of the list display area 42. Scroll display is performed with the group as a unit of scrolling, such as displaying the state in which the items of the “C” group are arranged at the top of the list display area 42 for a short time and then displaying the still image for a short time. Also good.

  Next, a case where a job is selected from the job list will be described as another example of the operation related to item selection from the list.

  FIG. 8 shows an example of the job list display screen 70 displayed on the display unit 31 of the operation display unit 30. There is a title column 71 at the top of the job list display screen 70, and a list display area 72 below it. In FIG. 8, the list display area 72 is surrounded by a broken line.

  The list display area 72 displays a job list. The job list is composed of one job and one line, and for each job, a job number, a job type, a user who submitted the job, and a job execution result are displayed.

  When a scroll operation (for example, a flick operation) is performed on the list display area 72, the title column 71 is switched to the index display area 73 and the cancel button 74 as shown in FIG. In the index display area 73, an index 75 of the job list is displayed. In the job list of this example, jobs are sorted in order of job numbers, and are grouped based on job numbers. Specifically, the groups are grouped as 1 to 10 groups, 11 to 20 groups, 21 to 30 groups, and so on. Therefore, information indicating the range of job numbers belonging to each group is displayed as an index 75 in the index display area 73.

  As shown in FIG. 9, the index 75a corresponding to the group to which the job (item) displayed at the top (top row) of the index display area 73 belongs has a different display form (for example, different) from the other indexes 75b to 75e. Color).

If the job list is sorted by job type (Kind),
Job types such as “Copy” and “Print” may be used as an index. If the job list is sorted by user name, “A”, “B”, etc. may be used as an index for the first letter of the user name.

  In this example, the number of selectable items is “1”. Therefore, to exit the scroll display, any item may be selected or the cancel button 74 may be pressed. The cancel button 74 may not be displayed.

  FIG. 10 shows a flow of operations performed by the CPU 11 (display control device) of the image processing apparatus 10 when a scroll operation is performed on the list display area 72 from the user on the job list display screen 70 of FIG. In the job list of this example, the number of selectable items is “1”.

  When the CPU 11 of the image processing apparatus 10 detects that the user has performed a scroll operation on the list display area 72 of the job list display screen 70 in FIG. 8, as shown in FIG. 9, the index of the job list is displayed in the index display area. (Step S301). The index display area 73 is provided in a display area for functions that are not used during scroll display and information that is not referenced. In the example of FIG. 9, an index display area 73 is provided in the area that was the title column 71.

  After displaying the index, the CPU 11 performs a scroll display operation determination process for determining a scroll display operation such as a scroll direction, a scroll unit, and a scroll speed according to the content of the scroll operation (for example, flick speed) (step S302). ), Scroll display is performed according to the contents determined in the processing (step S303). The scroll display operation determination process is the same as that shown in FIG.

  If there is no user operation during the scroll display (step S304; No), the process returns to step S302 and recalculates the scroll display operation such as decreasing the scroll speed using the elapsed time as a parameter (step S302). S302). The “scroll display” may include a state where the scrolling is stopped as a result of the deceleration, and is not limited to a state where the scrolling is actually performed.

  If a scroll operation is received again from the user during the scroll display (step S304; Yes, S305: scroll), the process returns to step S302 to recalculate the scroll display operation (step S302).

  If the user selects an index during scroll display (step S304; Yes, S305; select index), the first job (item) of the group corresponding to the selected index is the top (topmost) of the list display area 72. The display range is changed to come to (line) (step S306). Then, it returns to step S302 and recalculates the scroll display operation (step S302).

  If a job (item) selection operation or cancel button 74 operation is received from the user during scroll display (step S304; Yes, S305: item selection or cancel key), the index display is cleared (step S307) and scrolling is performed. The display is terminated (END).

  In the job list display screen 70 of FIG. 9, all indexes are displayed in the index display area 73. Therefore, the scroll operation for the index display area 73 is not accepted. If there is an index that is not displayed, it is better to add a display that shows that. For example, an arrow is displayed in the direction with the following index.

  In addition to the job list related to the job history, the image processing apparatus 10 also has a job list related to a job before processing (standby) and a job being processed. These job lists are also displayed in the same manner as the job list of the job history. Is possible.

  As described above, the image processing apparatus 10 displays the job list in the list display area 72 and then displays the index of the job list when the scroll operation is detected, and is necessary during the scroll display of the index display area 73. Since no information is displayed in the area of the title column 71, the index can be displayed even when the display screen is small, and the use of the index can reduce the trouble of scrolling.

  In addition, since the index of the group to which the item displayed in the list display area 72 belongs is displayed in a display form (for example, different color) different from the index of the other group, which group item is displayed in the list display area 72. For example, the user can easily determine whether or not the display range of the list should be changed by selecting an index.
