The present invention relates to an information processing apparatus, a non-transitory computer readable medium storing a program, and an information processing method.
JP4595807B describes an imaging apparatus including a control unit that controls to display a list of reduced images of a moving image, and a selection unit that selects the displayed reduced image, in which in a case of displaying the moving image corresponding to the reduced image selected by the selection unit in a size larger than the reduced image on a list display screen, the control unit controls a display position of the moving image so as not to interfere with display of the reduced image selected by the selection unit and a plurality of reduced images selectable by cursor moving.
For an image displayed on the screen, there is a case where a confirmation image is required to be displayed for a user to confirm the image. As the confirmation image, for example, an enlarged thumbnail image obtained by enlarging a thumbnail image may be used to allow the user to confirm contents of a file corresponding to the thumbnail image. Further, as another confirmation image, for example, an image for displaying contents of a document corresponding to an icon image may be used to allow the user to confirm contents of a function corresponding to the icon image.
In a case of displaying the confirmation images of these images, for example, in a case where the confirmation image is always displayed in the same direction with respect to these images, an area in which the confirmation image is displayed becomes smaller depending on a position of the image, and visibility of the user is reduced, and it is difficult to perform a confirmation work, in some cases.
Aspects of non-limiting embodiments of the present disclosure relate to an information processing apparatus, a non-transitory computer readable medium storing a program, and an information processing method that suppress a decrease in visibility of a user for a confirmation image, as compared with a case where the confirmation image is always displayed in the same direction with respect to an image.
Aspects of certain non-limiting embodiments of the present disclosure overcome the above disadvantages and/or other disadvantages not described above. However, aspects of the non-limiting embodiments are not required to overcome the disadvantages described above, and aspects of the non-limiting embodiments of the present disclosure may not overcome any of the disadvantages described above.
According to an aspect of the present disclosure, there is provided an information processing apparatus including a processor configured to display an instruction image for accepting an instruction of a user on an operation screen for accepting an operation of the user, and in a case where the user performs an operation of instructing to display a confirmation image for confirming information related to the instruction image, determine one direction based on a distance from the instruction image to ends of the operation screen in an up-down direction and a right-left direction, and perform control so that the confirmation image is displayed in the one direction from a predetermined specific area on the instruction image.
Exemplary embodiment(s) of the present invention will be described in detail based on the following figures, wherein:

Examples of the processor include general processors (e.g., CPU: Central Processing Unit) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, and programmable logic device).
In the embodiments above, the term “processor” is broad enough to encompass one processor or plural processors in collaboration which are located physically apart from each other but may work cooperatively. The order of operations of the processor is not limited to one described in the embodiments above, and may be changed.
The input unit 20 is an apparatus such as a pointing device by which the user inputs an operation.
For example, in a case where the input unit 20 is a mouse or the like, the user can designate a position on a screen of the display unit 40, a displayed image, or the like by performing a cursor movement operation or a click operation.
Further, in a case where the input unit 20 is a touch panel or the like, the user can designate a position on a screen or a displayed image by performing an operation of touching the touch panel with a finger or the like or an operation of maintaining the touched state of the finger or the like for a longer time than a predetermined time. In this case, the input unit 20 is provided integrally with the display unit 40.
In addition to the apparatus such as the pointing device described above, a keyboard or the like for performing a key input operation may be provided as the input unit 20.
The display unit 40 displays an operation screen 400, which is a screen for accepting an operation by the user, as illustrated in
On the operation screen 400, in addition to a document icon 410, a display instruction button 411, a confirmation image 420, a toolbar 430, and the like are displayed.
The document icon 410 is an example of an instruction image for accepting an instruction of the user. The instruction of the user includes selecting, browsing, moving a storage location, moving a display location of an instruction image, and the like for a document. Further, the display instruction button 411 is an image for giving an instruction related to display of the confirmation image 420. The confirmation image 420 is an image for allowing the user to confirm a content of the document related to the instruction image such as the document icon 410. The toolbar 430 is a collection of instruction units prepared to simplify operations on electronic documents by the user. Examples of the operation for this electronic document include operations of saving, printing, rotating, searching for, and encrypting the electronic document, an operation of bundling two or more electronic documents, and the like.
In the present exemplary embodiment, a size of the operation screen 400 on the display unit 40 can be changed by an operation of the user. Further, it is also possible to obtain a rectangular shape with an aspect ratio different from
The document icon 410 is an instruction image for accepting an instruction of the user on the document. The document icon 410 may be a thumbnail image for checking at least a part of a content of a file managed by file handling software. This thumbnail image is simply displayed as a reduced image of the original image, for example, in a case where the corresponding file is image data. In a case where the corresponding file is document data having a plurality of pages, a representative page such as the first page is displayed as the reduced image. The document icon 410 displayed as a thumbnail image functions as an icon for opening the corresponding file, for example.
In a case where a document displayed as a thumbnail image consists of a plurality of pages, an image (not illustrated) for accepting a change of the display page from the user may be displayed in a state of being associated with the document icon 410. In the present exemplary embodiment, the “page” is a set of pieces of data displayed as one surface on the operation screen 400 at a time.
The document icon 410 may be a tray used for the user to deliver an electronic document to a third party, a folder used for storing the electronic document, an electronic document, or the like represented by a pictogram.
The display instruction button 411 is an image for accepting an operation instructing display of the confirmation image 420 by the user, and is an example of an instruction button that is an image for accepting an instruction related to the display of the confirmation image 420. This instruction button is displayed in a state of being associated with the document icon 410. Further, instead of the display instruction button 411 illustrated in
In the present exemplary embodiment, the display instruction button 411 and a maintenance instruction button 412 are displayed so as to be superimposed on an upper right corner portion of the document icon 410. In this case, it is preferable that the display instruction button 411 and the maintenance instruction button 412 are displayed so as not to reduce visibility of the document icon 410, for example. For example, the display instruction button 411 is displayed to be smaller than the document icon 410. Further, the display instruction button 411 is displayed semi-transparently so that a superimposed portion on the document icon 410 can be seen through.
The confirmation image 420 is an image for allowing the user to confirm a content of the instruction image. The confirmation image 420 is displayed without starting a new program in a case where the user performs an operation to instruct the display. In the example in
In addition, as illustrated in
Functional Configuration of Image Display Apparatus 1
Next, a functional configuration of the image display apparatus 1 will be described.
The operation determination unit 101 determines whether or not a user operation is performed via the input unit 20 on the operation screen 400 (see
The distance determination unit 102 determines a distance from the instruction image (see
Further, the distance determination unit 102 according to the present exemplary embodiment determines a position of the instruction image on the operation screen 400, based on the distances from the instruction image to the end in the up-down direction and right-left direction
The display control unit 103 controls a display mode of the document icon 410, the confirmation image 420, the toolbar 430 (see
Further, the display control unit 103 controls to display an image captured by the image acquisition unit 106 as the instruction image. For example, a thumbnail image is taken from the image acquisition unit 106, and controlled to be displayed as the document icon 410 for opening the corresponding file.
The instruction button output unit 104 outputs an instruction button for giving an instruction related to display of the confirmation image 420, such as the display instruction button 411 for giving an instruction to display the confirmation image 420 or the maintenance instruction button 412 for giving an instruction to maintain the display of the confirmation image 420, to the display unit 40. This instruction button is displayed in a state of being associated with an instruction image such as the document icon 410.
The confirmation image output unit 105 takes out the confirmation image 420 acquired by the image acquisition unit 106, based on the determination of the operation determination unit 101 that the display of the confirmation image 420 is instructed. The confirmation image output unit 105 outputs the confirmation image 420 corresponding to the document icon 410 instructed by the user to the display unit 40 without starting a new program.
The image acquisition unit 106 acquires an image to be displayed on the display unit 40, such as an instruction image such as a document icon 410 or another icon, an instruction button output by the instruction button output unit 104, a confirmation image 420 output by the confirmation image output unit 105, and the like. For example, a thumbnail image is generated and acquired as the document icon 410, based on the document stored in the secondary storage unit 30. Further, for example, an image already stored in the secondary storage unit 30 is taken out and acquired as the confirmation image 420.
The image acquired by the image acquisition unit 106 is stored in a state of being taken out as the instruction image, the instruction button, and the confirmation image 420. The function of storing this image is realized by the non-volatile memory 14 (see

A process in a case of displaying the confirmation image 420 will be described with reference to
Further,
As illustrated in
The document icons 410 (410a, 410b, and 410c) and the toolbar 430 are displayed on the operation screen 400.

Further, the display area 421 illustrated in
The maintenance instruction button 412a illustrated in
Next, the description is continued with reference to the flowchart illustrated in
First, the operation determination unit 101 illustrated in
In a case where the document icon 410 is not designated in step S501 (NO in step S501), the process waits until the document icon is designated. In a case where the document icon 410 is designated (YES in step S501), the instruction button output unit 104 outputs and displays the display instruction button 411 (step S502). For example, in a case where there is a mouse over operation of locating the cursor 200 over the document icon 410a illustrated in
Next, the operation determination unit 101 determines whether or not the display instruction button 411a is designated based on an operation via the input unit 20 (step S503). The operation determination unit 101 according to the present exemplary embodiment determines, for example, that a mouse over operation on the display instruction button 411a is the designation on the display instruction button 411a.
In a case where the display instruction button 411a is not designated (NO in step S503), the process waits until the display instruction button 411a is designated. Ina case where the display instruction button 411a is designated (YES in step S503), the display control unit 103 determines one direction for displaying the confirmation image 420, based on a distance from the document icon 410a determined by the distance determination unit 102 to an end of the operation screen 400 in the up-down direction and the right-left direction (step S504). A procedure of determining one direction for displaying the confirmation image 420 based on the determination of the distance determination unit 102 will be described in detail below with reference to
Subsequently, the display control unit 103 secures an area from the predetermined specific area 416 determined on the document icon 410a to an end of the operation screen 400 in one direction as the display area 421 for displaying the confirmation image 420 (step S505).
In
Further,
In this manner, the display control unit 103 secures a rectangular area determined by the distance from the specific area to the end of the operation screen 400 in one direction and the width of the operation screen 400 in a direction intersecting with the one direction as the display area 421.
Next, the display control unit 103 determines a size for displaying the confirmation image 420a based on a size of the secured display area 421 (step S506). More specifically, in the display area 421, which is an area from the specific area to the end of the operation screen 400 in one direction, a display magnification of the confirmation image 420a is determined so that the entire confirmation image 420a is displayed in the largest size.
In the present exemplary embodiment, the display magnification of the confirmation image 420a is determined so that the entire confirmation image 420a can be displayed in consideration of margins Ma and Mb in the display area 421 in the up-down direction and right-left direction. This margin is a margin provided along four sides inside the display area 421, and the confirmation image 420a is displayed in a portion excluding the margins from the display area 421. As illustrated in
In
For example, in a case of displaying the vertically long confirmation image 420a in the display area 421, the display control unit 103 calculates a display magnification at which the width Y−2Ma, which is obtained by excluding the margin Ma in the up-down direction from a height Y of the display area 421 and the height of the confirmation image 420a coincide with each other, as a temporary display magnification. A width of the confirmation image 420a at this temporary display magnification is compared with the width X−2Mb, which is obtained by excluding the margin Mb in the right-left direction from the width X of the display area 421. In a case where the width of the confirmation image 420a at the temporary display magnification is equal to or less than X−2Mb, the entire confirmation image 420a can be displayed, so that the calculated temporary display magnification is determined as the size for displaying the confirmation image 420a. Further, in a case where the width of the confirmation image 420a at the temporary display magnification is more than the X−2Mb, at least a part of the confirmation image 420a protrudes, so that a display magnification at which the width of the confirmation image 420a and X−2Mb coincide with each other is recalculated, and is determined as the size for displaying the confirmation image 420a.
Further, for example, in a case of displaying the horizontally long confirmation image 420a in the display area 421, the display control unit 103 calculates a display magnification at which the width X−2Mb, which is obtained by excluding the margin Mb in the right-left direction from the width X of the display area 421 and the width of the confirmation image 420a coincide with each other, as the temporary display magnification. The width of the confirmation image 420a at this temporary display magnification is compared with the width Y−2Ma, which is obtained by excluding the margin Ma in the up-down direction from the height Y of the display area 421. In a case where the height of the confirmation image 420a at the temporary display magnification is equal to or less than Y−2Ma, the calculated temporary display magnification is determined as the size for displaying the confirmation image 420a. In a case where the height of the confirmation image 420a at the temporary display magnification is more than Y−2Ma, the display magnification at which the width of the confirmation image 420a and X−2Mb coincide with each other is recalculated and determined as the size for displaying the confirmation image 420a.
Further, in step S507, the display control unit 103 determines a position for displaying the confirmation image 420a, based on a position of the specific area 416.
For example, as illustrated in
In this manner, in a case where a margin is generated in a direction parallel to the one direction, the display control unit 103 controls so that the confirmation image 420a is displayed closer to the specific area 416.
Further, for example, as illustrated in
In this manner, in a case where a margin is generated in a direction orthogonal to the one direction, between the ends of the operation screen 400 in the orthogonal direction, the display control unit 103 controls the confirmation image 420a to be displayed closer to the end closer to the specific area.
As described above, by controlling the position at which the confirmation image 420a is displayed based on the position of the specific area, it becomes easy to understand a correspondence between the instruction image such as the document icon 410a and the displayed confirmation image 420a.
Further, for example, as illustrated in
Next, the confirmation image output unit 105 takes out the confirmation image 420a from the image acquisition unit 106, and outputs the confirmation image 420a to the display unit 40 to display the confirmation image 420a in the one direction, in the size, and at the position determined insteps S504, S506, and S507 (step S508). In the example in
As illustrated in
Further, the confirmation image 420a may be displayed to be superimposed on at least a part of the document icon 410a depending on the direction or the size, the position for displaying the confirmation image 420a, with or without the margin or the size of the display area 421, and the like. For example, as illustrated in
In this manner, the confirmation image 420a may be displayed at a position at which the confirmation image 420a is superimposed on at least a part of the document icon 410a. With this configuration, as compared with a case where the confirmation image is displayed at a position at which the confirmation image is not superimposed on the document icon 410a, it is possible to increase the display area 421 secured for displaying the confirmation image 420a.
Further, regardless of a case where the display instruction button 411a is displayed in association with the specific area 416 as in the present exemplary embodiment or a case where the display instruction button 411a is displayed without being associated with the specific area 416, the confirmation image 420a may be displayed at a position at which the confirmation image 420a is not superimposed on the display instruction button 411a on the document icon 410a. With such a configuration, the user can easily recognize a document which the user operates with a display instruction button. In a case where the display instruction button 411a is changed to the maintenance instruction button 412a, the maintenance instruction button 412a becomes easier to operate.
Subsequently, the instruction button output unit 104 outputs and displays the maintenance instruction button 412 to the display unit 40 (step S509). The maintenance instruction button 412 accepts that the display of the confirmation image 420 is set to the display maintenance state. For example, in a case where the display instruction button 411a illustrated in
Subsequently, the operation determination unit 101 determines whether or not the maintenance instruction button 412 is designated (step S510). In the present exemplary embodiment, the operation determination unit 101 determines, for example, a click operation on the maintenance instruction button 412 as designation on the maintenance instruction button 412.
In a case where the maintenance instruction button 412a is not designated in this step S510 (NO in step S510), the process waits until the maintenance instruction button 412a is designated. In a case where the maintenance instruction button 412a is designated (YES in step S510), the display control unit 103 shifts to the display maintenance state (step S511). In the example illustrated in
Here, a scroll operation or the like may be performed over the operation screen 400 in the display maintenance state, and the document icon 410a may be moved. In the present exemplary embodiment, even in a case where the document icon 410a is moved, the size and the position of the confirmation image 420a maintain the settings when shifting to the display maintenance state. For example, as illustrated in
Next, the operation determination unit 101 determines whether or not an operation of canceling the display maintenance state is performed (step S512). The operation determination unit 101 according to the present exemplary embodiment determines, for example, performing a click operation at a position other than the display area 421 or a click operation on the maintenance instruction button 412a again, as the operation of canceling the display maintenance state. Ina case where the canceling operation is not performed (NO in step S512), the display maintenance state is continued. In a case where the canceling operation is performed (YES in step S512), the display control unit 103 cancels the display maintenance state of the confirmation image 420a (step S513).
The process of displaying the confirmation image 420a is completed according to the above processing procedure.
As described above, the image display apparatus 1 according to the present exemplary embodiment determines one direction according to a distance from the document icon 410a to ends of the operation screen 400 in the up-down direction and right-left direction, and controls the confirmation image 420a to be displayed in the one direction from the specific area 416 on the document icon 410a, in a case where the display of the confirmation image 420a is instructed from an operation of the user.
Although
Procedure to Determine One Direction
Next, a procedure of determining one direction will be described in detail with reference to
Here, as illustrated in
Further, a distance from the predetermined specific area 416 on the document icon 410a to the end of the operation screen 400 in the left direction is defined as Xa′, a distance from the predetermined specific area 416 to the end in the right direction is defined as Xb′, a distance from the predetermined specific area 416 to the end in the upward direction is defined as Ya′, and a distance from the predetermined specific area 416 to the end in the downward direction is defined as Yb′. In the present exemplary embodiment, the display instruction button 411a is displayed in association with the specific area 416. As illustrated in
Further, in the following description, for convenience, the operation screen 400 may be divided into four areas of “upper left”, “lower left”, “upper right”, and “lower right”. As illustrated in
First, the distance determination unit 102 acquires the distances Xa, Ya, Xb, and Yb from the reference positions 415a and 415b of the document icon 410a to the ends of the operation screen 400 (step S601).
Next, in step S602, the distance determination unit 102 determines whether or not Xa≤Xb is satisfied. In a case of Xa≤Xb (YES in step S602), the process proceeds to step S603 to determine whether or not Ya≤Yb is satisfied. In a case of Ya≤Yb (YES in step S603), it is determined that the document icon 410a is in the “upper left” of the operation screen 400 (step S604).
Further, in step S605, regarding the distance Xb′ from the specific area 416 to the end of the operation screen 400 in the right direction and the distance Yb′ from the specific area 416 to the end in the downward direction, the distance determination unit 102 determines whether or not Yb′≤Xb′ is satisfied. In a case of Yb′≤≤Xb′ (YES in step S605), the display control unit 103 determines that the one direction is the “right” direction (step S606). In a case where Yb′≤<Xb′ is not satisfied (Yb′>Xb′) (NO in step S605), the display control unit 103 determines the one direction is the “downward” direction (step S613).
In a case of Ya≤Yb is not satisfied in step S603 (NO in step S603), the distance determination unit 102 determines that the document icon 410a is in the “lower left” of the operation screen 400 (step S607).
Next, in step S608, it is determined whether or not Xb′≤Ya′ is satisfied. In a case of Xb′≤Ya′ (YES in step S608), the display control unit 103 determines that the one direction is the “upward” direction (step S609). In a case where Xb′≤Ya′ is not satisfied (Xb′>Ya′) (NO in step S608), the display control unit 103 determines that the one direction is the “right” direction (step S606).
Further, in a case where Xa≤<Xb is not satisfied (Xa>Xb) (NO in step S602), the process proceeds to step S610 to determine whether or not Ya≤<Yb is satisfied. In a case of Ya≤Yb (YES in step S610), it is determined that the document icon 410a is in the “upper right” of the operation screen 400 (step S611).
In step S612, it is determined whether or not Xa′≤Yb′ is satisfied. In a case of Xa′≤Yb′ (YES in step S612), the display control unit 103 determines that the one direction is the “downward” direction (step S613). In a case where Xa′ Yb′ is not satisfied (Xa′>Yb′) (NO in step S612), the display control unit 103 determines that the one direction is the “left” direction (step S616).
In a case where Ya≤Yb is not satisfied (Ya>Yb) (NO in step S610), the distance determination unit 102 determines that the document icon 410a is in the “lower right” of the operation screen 400 (step S614).
In step S615, it is determined whether or not Ya′≤Xa′ is satisfied. In a case of Ya′≤Xa′ (YES in step S615), the display control unit 103 determines that the one direction is the “left” direction (step S616). In a case where Ya′≤Xa′ is not satisfied (Ya′>Xa′) (NO in step S615), the display control unit 103 determines that the one direction is the “upward” direction (step S609).
With the above procedure, the process of determining the one direction is completed.
In the present exemplary embodiment, based on the distances Xa, Xb, Ya, and Yb from the reference positions 415a and 415b to the ends of the operation screen 400, the position of the document icon 410a is determined. Further, any two distances among the distances Xa′, Xb′, Ya′, and Yb′ from the specific area 416 to the ends of the operation screen 400 are compared with each other to determine one direction. In another exemplary embodiment, the distances Xa, Xb, Ya, and Yb may simply be compared and a direction corresponding to the largest distance may be determined as the one direction. Further, for example, the distances Xa′, Xb′, Ya′, and Yb′ may be simply compared, and a direction corresponding to the largest distance may be determined as the one direction.
In the present exemplary embodiment described above, the predetermined specific area 416 and the two reference positions 415a and 415b different from the specific area 416 are provided on the document icon 410a. Based on the distance from the specific area 416 to the ends of the operation screen 400 and the distance from the reference positions 415a and 415b to the ends of the operation screen 400, one direction for displaying the confirmation image 420a is determined.
In Modification Example 1 of the procedure of determining the one direction, a reference position 415c is provided inside the specific area 416, and one direction is determined based on a distance from the reference position 415c to an end of the operation screen 400.
In
As illustrated in
Next, in Modification Example 2 of the procedure of determining the one direction, the one direction is determined based on a distance from the specific area 416 to an end of the operation screen 400 without providing a reference position.
In Modification Example 2, the specific area 416 is defined so as to correspond to an area in which the document icon 410a is displayed. In this case, for example, distances Xc′, Xd′, Yc′, and Yd′ from ends of the document icon 410a in the up-down direction and the right-left direction to ends of the operation screen 400 in the same direction are compared with each other, so that it is possible to determine a direction corresponding to the largest distance as the one direction.
As described above, a method of obtaining the distance from the instruction image such as the document icon 410a to the end of the operation screen 400, which is used to determine the one direction, can have various modes. More specifically, a distance or the like from each side of the instruction image in the up-down direction and right-left direction, a predetermined specific area on the instruction image, a reference position predetermined on the instruction image, or the like to the end of the operation screen 400 in the up-down direction and right-left direction is obtained.
In the present exemplary embodiment described above, the example is illustrated in which the entire confirmation image 420a is displayed in the maximum size determined by the distance from the reference position 415 or the specific area 416 to the end of the operation screen 400. Here, for example, a prototype image that is a prototype of the confirmation image 420a may be a small image such as data obtained by scanning a business card, so a width and a height of the display area 421 may be larger than this prototype image. At this time, the confirmation image 420a is displayed in a size exceeding a size appropriate for confirming the document icon 410a, and an operation of the user on the operation screen 400 may be hindered.
Therefore, the size of the displayed confirmation image 420a may be determined based on a size of the prototype image which is the prototype of the confirmation image 420a. For example, in the process of determining the size for displaying the confirmation image 420a, it is possible to acquire the size (width and height) of the prototype image from pixel information or the like, and to set the size as an upper limit of the size (width and height) of the displayed confirmation image 420a.
