Description

  The present invention relates to a display device and a display control program, and more particularly to a technique for scrolling and displaying an image displayed on a display unit.

  Some display devices scroll the display screen of the display unit in accordance with a touch operation performed by the user on the display screen of the display unit. The scroll display executed according to the touch operation such as swipe is intuitive and easy to operate, and further, since the scroll bar display can be eliminated or reduced, there is an advantage that the image display area in the display unit can be enlarged.

  However, if the scroll bar is not displayed or is small, the user may not be aware that the display screen can be scrolled, that is, there is an image that is not displayed in the display area of the display unit but should be displayed. For example, the image forming apparatus may display a list in which a plurality of pieces of job information are listed in a predetermined order. The job information is displayed by listing multiple job names in order of reception time, but if the scroll bar is not displayed or small, the user may not be aware of the hidden job information without being displayed. .

  For this reason, when a scrollable image is displayed on the display unit, a display device that temporarily scrolls the image until its final position is displayed has been proposed (for example, see Patent Document 1 below).

JP-A-4-234789

  However, since the display device disclosed in Patent Document 1 scrolls up the display target image until the final position is displayed, the user checks the content from the top position of the image and performs an operation. In this case, it is necessary to perform an operation for instructing scroll-down to display the head position of the image on the display screen of the display unit, which is troublesome for the user.

  The present invention has been made in view of the above circumstances, and the image displayed on the display unit is an image that is entirely displayed on the display unit by scroll display without troublesome user operations. The purpose is to make it easy for the user to grasp.

  A display device according to an aspect of the present invention includes a display unit that displays an image, a display control unit that performs display control of the display unit, and an operation reception unit that receives a touch operation on the display unit by a user as an operation instruction. The display control unit is configured such that an image to be displayed on the display unit is larger than a predetermined display area of the display unit, and scroll display is performed in a vertical direction or a horizontal direction on the display screen of the display unit. If it is determined that the scroll image can display the entire area of the image in the display area, the part of the scroll image that has moved in the vertical or horizontal direction to a predetermined position away from the head position is Display in the display area, and then scroll the scroll image until the head position of the scroll image reaches the end of the display area in the moving direction. It is scrolled and displayed on the display area.

  Further, a display control program according to one aspect of the present invention causes a computer to function as a display control unit that performs display control of a display unit, and an operation reception unit that receives a touch operation on the display unit by a user as an operation instruction, The display control unit is configured such that an image to be displayed on the display unit is larger than a predetermined display area of the display unit, and the entire area of the image is displayed by scrolling in a vertical direction or a horizontal direction on the display screen of the display unit. When it is determined that the scroll image can be displayed in the display area, a part of the scroll image that has moved in the vertical or horizontal direction to a predetermined position away from the head position is displayed in the display area. Thereafter, the scroll image is scrolled until the head position of the scroll image reaches the end of the display area in the moving direction. So as to display on the display area by scrolling the image is intended to further function the computer.

  According to the present invention, when a scroll image in which the entire area is not displayed in the display area unless scroll display is performed is displayed on the display unit, the scroll image includes an image part that is not yet displayed on the display unit. Can be easily grasped by visually recognizing the contents displayed by scrolling. Furthermore, the user can confirm the content from the top position of the scroll image without performing an operation to instruct the scroll operation to display the top position of the scroll image in the display area of the display unit. The content of the scroll image can be easily grasped without performing a troublesome operation.

  Hereinafter, a display device and a display control program according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram schematically showing the main internal configuration of an image forming apparatus as a display apparatus according to the first embodiment of the present invention.

  The display device according to the first embodiment is, for example, the image forming apparatus 1. The image forming apparatus 1 has a plurality of functions such as a copy function, a printer function, a scanner function, and a facsimile function, for example. The image forming apparatus 1 includes a control unit 10, a document feeding unit 6, a document reading unit 5, an image forming unit 12, an image memory 32, an HDD (Hard Disk Drive) 92, a fixing unit 13, a sheet feeding unit 14, and an operation unit 47. A facsimile communication unit 71, and a network interface unit 91.

  The HDD 92 is a large-capacity storage device that stores document images read by the document reading unit 5 and stores a display control program according to an embodiment of the present invention.

  The operation unit 47 receives instructions such as an image forming operation execution instruction and a document reading operation execution instruction from the operator for various operations and processes that can be executed by the image forming apparatus 1. The operation unit 47 includes a display unit 473 that displays operation guidance to the operator. The display unit 473 is a touch panel, and the operator can operate the image forming apparatus 1 by touching buttons and keys displayed on the screen.

  The control unit 10 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and a dedicated hardware circuit. The control unit 10 includes a control unit 100, an operation reception unit 101, a login processing unit 102, a job management unit 103, a display control unit 104, a login information storage unit 105, and a job information storage unit 106. ing.

  The control unit 10 operates in accordance with a display control program stored in the HDD 92 and the like, by the control unit 100, the operation receiving unit 101, the login processing unit 102, the job management unit 103, the display control unit 104, and the login information storage unit 105. , And the job information storage unit 106. However, the control unit 100 or the like can be configured by a hardware circuit, regardless of the operation according to the display control program by the control unit 10 or the like. The same applies to each embodiment unless otherwise specified.

  The login information storage unit 105 stores login information such as a login ID and a password, which are identification information unique to a user necessary for logging in to the image forming apparatus 1.

  The job information storage unit 106 receives the time and type of each job (for example, copy printing, printer printing, fax reception printing, fax transmission, scan storage), job name, user name, and status (for example, waiting, processing, Job information indicating the contents of the job such as “completed” is stored.

  The control unit 100 governs overall operation control of the image forming apparatus 1. The control unit 100 includes a document feeding unit 6, a document reading unit 5, an image forming unit 12, an image memory 32, an HDD 92, a fixing unit 13, a sheet feeding unit 14, an operation unit 47, a facsimile communication unit 71, and a network interface unit 91. Are connected, and drive control of these parts is performed.

  The operation reception unit 101 receives a user operation input to the operation unit 47 by the user. The display unit 473 as the operation unit 47 has a touch panel function. By this touch panel function, a touch operation on the display screen of the display unit 473 by the user, for example, a gesture operation such as swipe or flick is input as a user operation, and the operation is accepted. The unit 101 receives the user operation.

  The login processing unit 102 determines whether or not the input login information is stored in the login information storage unit 105 when the operation reception unit 101 receives the login information input by the user operation on the operation unit 47. When it is determined that the login information is stored, the user is permitted to log in to the image forming apparatus 1.

  The job management unit 103 stores job information indicating the job of the image forming apparatus 1 in the job information storage unit 106, and updates the job information stored in the job information storage unit 106 according to a change in job status.

  The display control unit 104 performs display control of the display unit 473. For example, when the operation receiving unit 101 receives a request for scrolling display contents of the display unit 473 from the user, the display control unit 104 scrolls and displays an image displayed on the display unit 473 in response to the request.

  Next, display processing by the image forming apparatus 1 will be described. FIG. 2 is a flowchart showing display processing by the image forming apparatus 1. Here, a case where display of a job list is requested by a user will be described as an example.

  When the operation receiving unit 101 receives a job list display request instruction from the user, the control unit 100 reads job information from the job information storage unit 106 (S1), and the display control unit 104 displays a job indicating the read job information. A list image is created (S2).

  FIG. 3 is a diagram illustrating an example of a display image including a job list image. The display image D1 includes a job list image J1 composed of a plurality of items (number, reception time, type, job name, user name, status), an upper bar Bu on which a title name “job confirmation screen” and item names are displayed, It includes a “Close” for closing the display image D1 and a lower bar Bd having a button B1 displayed. The job list image J1 fits in the scroll area E1 (FIG. 4) in the display image D1. The scroll area is an example of a predetermined display area in the claims.

  However, if the display control unit 104 creates a job list image including a lot of job information, the job list image may not fit in the scroll area in the display image. An example of a job list image J2 having more job information than the job list image J1 is shown in FIG. The display image D2 shown in FIG. 4 includes a job list image J2, a scroll area E1 for scrolling the job list image J2, an upper bar Bu, and a lower bar Bd. Note that ST and ED in the figure indicate the head position and the final position of the job list image J2, respectively.

  Subsequently, the display control unit 104 determines whether or not the job list image created in S2 fits in the scroll area E1, that is, whether or not the scroll image cannot be displayed in the scroll area E1 unless scroll display is performed. S3). If the display control unit 104 determines that the job list image created in S2 is a scroll image (YES in S3), the head position ST of the scroll image (described using the job list image J2 (FIG. 4) as an example) The distance L1 from the final position ED is calculated (S4).

  Then, the display control unit 104 sets the scroll speed V1 so that the scroll speed becomes slower as the distance L1 calculated in S4 becomes longer (S5). For example, the display control unit 104 sets a reference value for the scroll speed in advance, and calculates the scroll speed V1 using, for example, a formula of V1 = reference value / L1.

  As shown in FIG. 5A, the display control unit 104 determines a predetermined position away from the head position ST of the job list image J2 that is a scroll image (in this embodiment, the predetermined position is set to half). For example, in the job list image J2, the job list image J2 and the upper bar are arranged so that the display portion displaying the job information indicated by “number 0003” is arranged at the upper end of the scroll area E1. A display image D2 including Bu and the lower bar Bd is displayed on the display unit 473 (S6).

  After this display, the display control unit 104 starts scrolling down to scroll the displayed job list image J2 downward at the scroll speed V1 set in S5 (S7). For example, as shown in FIG. 5B, the display control unit 104 performs the scroll down until the head position ST of the job list image J2 reaches the upper end of the scroll area E1 (YES in S8). Thereafter, the display control unit 104 ends the scroll down (S9).

  On the other hand, if the display control unit 104 determines that the job list image created in S2 is not a scroll image (NO in S3), the display image including the job list image is displayed as it is in the scroll area E1 of the display unit 473. (S10). That is, the display control unit 104 does not display the image including the portion indicating the predetermined position and perform the scroll down. For example, as shown in FIG. 3, when the job list image is a job list image J1 including only four job information, the display control unit 104 displays the display image D1 including the job list image J1 on the display unit 473. To display as it is.

  According to the first embodiment, when the display unit 473 displays a display image including a job list image that cannot be displayed entirely at once in the scroll area E1, the display control unit 104 uses the scroll image as the scroll image. Is displayed on the display unit 473 after the image including the portion indicating the predetermined position is displayed in the scroll area E1, and the job list image is displayed to the user. It can be easily grasped that an image part that cannot be displayed in the part 473 is included.

  When the scroll-down is completed, the top of the job list image is displayed on the display unit 473. Therefore, the user can check the content from the top position of the job list image without performing any display operation. Thus, for example, since an operation instruction necessary for image formation can be input to the operation unit 47, the user can easily grasp the contents of the job list image without performing troublesome operations.

  Furthermore, in the above embodiment, the display control unit 104 changes the scroll speed V1 according to the length of the scroll image (job list image J2). It becomes possible to grasp the length (size) of the job list image.

  Next, a second embodiment of display processing by the image forming apparatus 1 will be described. FIG. 6 is a flowchart showing a second embodiment of display processing by the image forming apparatus. Note that description of the same processing as in the first embodiment is omitted.

  In the first embodiment, the display control unit 104 once displays a portion of the job list image (scroll image) that has moved downward to a predetermined position away from the head position in the scroll region of the display unit 473, and then the above. Although the display process of scrolling down is performed, the second embodiment is different from the first embodiment in that a restriction is imposed on the execution of the display process. In the second embodiment, it is assumed that, before entering S11, a login ID and a password are input by an operation of the operation unit 47 by the user, and login to the user is permitted by the login processing unit 102.

  In the second embodiment, when the display control unit 104 determines that the created job list image is a scroll image (YES in S13), the display control unit 104 further displays the scroll image in the scroll area from the head position. In addition, it is determined whether the rear end of the scroll image displayed in the scroll area is interrupted in the middle of the image indicating any job information. That is, the display control unit 104 determines whether or not the lower end of the scroll area E1 is in a state where it does not coincide with the separation portion between the images indicating the job information (S14). FIG. 7A is a diagram showing a case where the lower end of the scroll area E1 coincides with a separation portion between images indicating job information, and FIG. 7B is an image where the lower end of the scroll area E1 indicates job information. It is the figure which showed the case where it does not correspond with the delimiter part. As shown in FIG. 7B, when the lower end of the scroll area E1 does not coincide with the job information delimiter, the job list image J2 is displayed in the scroll area E1 without performing display processing with scroll-up. It is possible to make the user easily notice that an image portion that is not completely cut is included.

  If the display control unit 104 determines that the lower end of the scroll area E1 does not match the job information delimiter (“does not match” in S14), the display image including the job list image is displayed as it is. It is displayed in the scroll area E1 of 473 (S21). That is, the display process without scroll down is performed without performing the display process with scroll down.

  On the other hand, if the display control unit 104 determines that the lower end of the scroll area E1 matches the delimiter of the job information (“match” in S14), the display control unit 104 determines that the match is first after the login process. It is determined whether it is the first time (S15).

  Here, when the display control unit 104 determines that the determination is not the first time after the login process (NO in S15), that is, when the display process with the scroll down has already been performed once. The display process without scroll down is performed (S21). In other words, the user has once viewed the display by the display process with scroll down, and seems to have already grasped that the displayed job list image includes an image portion that has not been displayed in the scroll area. Therefore, the display process with scroll down is omitted.

  On the other hand, when the display control unit 104 determines that the determination is the first time after the login process (YES in S15), the display control unit 104 further determines a predetermined value from the operation instruction immediately before the operation reception unit 101 has received. It is determined whether time has passed (S16).

  Here, when the display control unit 104 determines that a predetermined time (for example, 2 minutes) has not elapsed since the reception of the previous operation instruction (NO in S16), the display process without scrolling down is performed. (S21).

  On the other hand, when the display control unit 104 determines that a predetermined time has elapsed since the reception of the previous operation instruction (YES in S16), the display control unit 104 displays the information shown in FIG. As shown in FIG. 4, the display including the job list image J2 is arranged such that a predetermined position apart from the head position ST of the job list image J2 (FIG. 4) which is a scroll image is arranged at the upper end of the scroll area E1. The display process with the scroll-down of displaying the image D2 on the display unit 473 (S17) and then starting the scroll-down upward of the job list image J2 (S18) is performed. That is, since the user has visually recognized the display by the display process with scroll down once and the predetermined time has elapsed, the displayed job list image is not divided into display areas in the scroll area. Since there is a possibility that it cannot be immediately remembered whether or not it is included, the display control unit 104 executes display processing with scroll-down.

  According to the second embodiment, the scroll display is not performed every time, but only when it is necessary, such as when there is a possibility that the job list image may not include an image portion that has not been displayed in the scroll area. Therefore, when the necessity for the user is low, the display process with scroll down is omitted, and the user can be prevented from feeling bothered. On the other hand, since the display process with scroll down is executed when it is really necessary, it is possible to accurately notify the user that the job list image includes an image portion that has not been displayed in the scroll area.

  Next, a third embodiment of display processing by the image forming apparatus 1 will be described. FIG. 8 is a flowchart illustrating a third embodiment of display processing by the image forming apparatus. Note that description of processing similar to that in the first or second embodiment is omitted.

  In the third embodiment, the scroll-up start position is changed and set according to the length of the job list image that is a scroll image. Further, when the job list image is composed of a plurality of images, The present embodiment is different from the first and second embodiments in that different display processing is performed.

  In the third embodiment, when the display control unit 104 determines that the created job list image is a scroll image (YES in S33), the job list image is composed of a plurality of images, and each of the images is found. It is determined whether the image has been created (FIG. 9 below) (S34).

  FIG. 9 shows an example in which the job list image is composed of a plurality of images and each image has a heading image. The job list image J3 shown in FIG. 9 includes a plurality of job information, and the plurality of job information is divided into three group images (print job image H1, transmission job image H2, and saved job image H3). A heading image is formed on the group image. In this example, the print job image H1 has a header image im1, the transmission job image H2 has a header image im2, and the saved job image H3 has a header image im3.

  If the display control unit 104 determines that the job list image has been created as having the plurality of group images and having the heading image (YES in S34), the head position of the job list image J3 (FIG. 9) A heading image (final heading) formed at a position farthest from ST is specified (S42), and a distance L3 from the head position ST to the heading image (final heading) is calculated (S43).

  Subsequently, as the calculated distance L3 increases, the display control unit 104 increases the scroll speed V3 until the head position ST of the job list image J3 reaches the upper end of the scroll area regardless of the distance L3. The scroll speed V3 is set so that the scroll down time is constant (S44). The display control unit 104 calculates the scroll speed V3 using, for example, a mathematical formula of V3 = L3 / scroll display time.

  As shown in an example in FIG. 11A, the display control unit 104 first sets the job list image J3 so that the final heading, here, the upper end of the heading image im3 is arranged at the upper end of the scroll area E1. A display image D3 including the list image J3 is displayed on the display unit 473 (S44).

  On the other hand, if the display control unit 104 determines that the job list image is not made of the plurality of group images and has the heading image (NO in S34), the description will be given using the example of FIG. Then, the distance L1 from the head position ST to the final position ED of the job list image J2 is calculated (S35). Then, the display control unit 104 calculates the distance L2 from the head position ST to the intermediate position CN by multiplying the calculated distance L1 by, for example, 0.5, thereby calculating the intermediate position CN of the job list image J2. Specify (S36).

  Subsequently, the display control unit 104 scrolls down until the head position ST of the job list image J3 reaches the upper end of the scroll area regardless of the distance L2, as the distance L2 increases. The scroll speed V2 is set so that the time becomes constant (S37). For example, the display control unit 104 sets a scroll display reference time in advance, and sets the scroll speed V2 using a formula of V2 = L2 / scroll display reference time.

  As shown in FIG. 10A, the display control unit 104 displays the display image D2 including the job list image J2 so that the intermediate position CN of the job list image J2 is arranged at the upper end of the scroll area E1. (S38).

  After the processing in S38, the display control unit 104 starts scrolling down the job list image J2 displayed at this time at the scroll speed V2 set in S37 (S39). For example, as shown in FIG. 10B, the display control unit 104 scrolls down until the head position ST of the job list image J2 reaches the upper end of the scroll area E1 (YES in S40). The scroll down is finished (S41).

  Alternatively, after the processing of S45, the display control unit 104 starts scrolling down the job list image J2 displayed at this time at the scroll speed V3 set in S44 (S39). For example, as shown in FIG. 11B, the display control unit 104 scrolls down until the head position ST of the job list image J2 reaches the upper end of the scroll area E1 (YES in S40). The scroll down is finished (S41).

  According to the third embodiment, as the length of the job list image J2 (distance from the leading position ST to the final position ED) increases, the scroll amount by scrolling down increases. Based on the size, it becomes easy to grasp the length of the job list image (the size of the non-displayed image portion). In addition, when the job list image has a heading image for each of a plurality of group images, the user can visually recognize all the heading images during the scroll-down display. Makes it easier for users to understand the configuration.

  In the above description, when the display control unit 104 determines that the job list image has been created with the plurality of group images and the index image (YES in S34), the top of the job list image J3 is displayed. The heading image (final heading) formed at the position farthest from the position ST is specified (S42), and the distance L3 from the head position ST to the heading image (final heading) is calculated (S43). The heading image specified by the display control unit 104 as described above is not limited to this, and may be a heading image of any of the second and subsequent group images as viewed from the head position of the job list image. In this case, it is not necessary to set the scroll speed based on the distance to the identified headline image.

  In the first to third embodiments, the scroll display in the vertical direction has been described. However, the present invention is not limited to this, and the scroll display in the horizontal direction can be handled. This is effective when the scanned document image is displayed side by side on the display unit 473 and previewed or when the image formed on the recording medium by the image forming unit 12 is displayed side by side on the display unit 473. This will be described below as a fourth embodiment.

  First, an example of a procedure for creating a preview image for preview display will be described. For example, when the operation accepting unit 101 accepts an instruction for a preview display request for a document image from the user, the control unit 100 reads the document image from the HDD 92, and the display control unit 104 reads the document image read by the control unit 100. Create a preview image to show.

  FIG. 12 is a diagram illustrating an example of a display image including a preview image. The display image D4 includes a preview image PV1 for previewing a plurality of document images, an upper bar Bu on which a title name “preview screen” is displayed, and a button displaying “Close” for closing the display image D4. And a lower bar Bd having B1. This preview image PV1 fits in the scroll area E2 (FIG. 13) in the display image D4.

  However, when the display control unit 104 creates a preview image including a large number of document images, the preview image may not fit in the scroll area in the display image. FIG. 13 shows an example of the preview image PV2 having more document images than the preview image PV1. The display image D5 illustrated in FIG. 13 includes a preview image PV2, a scroll area E2 in which the preview image PV2 is scrolled, an upper bar Bu, and a lower bar Bd. Note that ST and ED in the figure indicate the head position and the final position of the preview image PV2, respectively.

  The display control unit 104 scrolls the preview image PV2 to be displayed on the display unit 473 to be larger than the scroll area E2 of the display unit 473 so that the entire area of the preview image PV2 can be displayed in the scroll area E2 by scroll display in the horizontal direction. If it is determined that the image is an image, as shown in FIG. 14A, a predetermined position apart from the head position ST in the scroll image (in this embodiment, the predetermined position is separated by a half page). For example, in the preview image PV2, the preview image PV2, the upper bar Bu, and the lower bar Bd are arranged so that the display portion displaying the document image indicated by “image 3” is arranged at the left end of the scroll area E2. A display image D5 including the above is displayed on the display unit 473.

  After this display, the display control unit 104 displays the document image indicated by the preview image PV2 portion hidden to the left of the scroll area E2, as shown in FIG. 14B, the head position ST of the preview image PV2. Until the left edge of the scroll area E2 is reached, the preview image PV2 being displayed is scrolled to the right. Thereby, also in the case of the scroll display in a horizontal direction, the effect equivalent to the case of the scroll display in a vertical direction can be exhibited.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. In the above embodiment, a display device according to an embodiment of the present invention is described using a multifunction peripheral that is an image forming apparatus. However, this is merely an example, and a copy function, a printer function, a scanner function, Other image forming apparatuses having a facsimile function, other electronic devices, and the like may be used.

  Moreover, in the said embodiment, the structure and process demonstrated using FIG. 1 thru | or FIG. 14 are only one Embodiment of this invention, and are not the meaning which limits this invention to the said structure and process.
