Description

  The present invention relates to a display control device, a display control method, and a display control program used in, for example, an image forming apparatus in which a display unit of an operation panel is configured by a touch panel.

  In recent years, MFPs (Multi Function Peripherals), which are multifunction digital image forming apparatuses, have been widely used in which a display unit of an operation panel provided in a main body is configured with a touch panel. The image can be edited by touch operation.

  As an image editing example, additional images (hereinafter referred to as stamps) such as logos, marks, dates, copy prohibitions, etc. (hereinafter referred to as stamps) are superimposed on each original image (also referred to as background image) for printing or transmission and added as layers (Combining) and printing or transmission may be possible in that state. Such image superposition is generally performed by a user dragging and dropping the stamp onto the background image by a touch operation, so that the stamp can be positioned at a predetermined position of the background image.

  Conventionally, there has been proposed a technique for enlarging a character area and an image area at a predetermined magnification when an enlargement operation is performed on images of the character area and the image area. For example, a technology is disclosed in which an image can be scrolled when operated while a function key is pressed while a character can be scrolled when operated without pressing a function key (see, for example, Patent Document 1).

JP 2011-198144 A

  By the way, in the MFP or the like, the user touches the stamp on the preview screen displayed on the operation panel with a finger and moves it on the background image by dragging, and enlarges / reduces it to a desired size, and then stamps the stamp. In some cases, the background image is arranged at a predetermined position.

  For example, in the preview screen, when the stamp edit key is pressed to set the operation target as a stamp and the stamp is enlarged in that state, if the operation is continued, the screen becomes full. Since it cannot be larger than that, conventionally, the image display key is pressed to switch the operation target, the entire image is reduced until the stamp can be enlarged, and the stamp edit key is pressed again to enlarge and move the stamp. I had to step on.

  On the other hand, in the case of reducing the stamp, similarly, the editing key is pressed to set the operation object as a stamp, and the stamp is moved to an approximate position in a wide display range to perform the reduction operation. If the operation is continued, the target stamp becomes small, so that the operation becomes difficult and detailed positioning becomes difficult. Therefore, conventionally, the image display key is pressed to switch the operation target to the entire image, the stamp can be reduced, the entire image is enlarged to a magnification that allows detailed positioning, the display range is scrolled, and the stamp edit key is again displayed. The procedure of switching the operation target to the stamp by pressing and moving it so that the size and position can be determined has been taken.

  As described above, when the size of the stamp becomes excessive when moving with enlargement / reduction to add the stamp to the background image, the display range must be adjusted by switching the operation target. There was a problem that the operation was troublesome.

  Note that the technology described in the above-mentioned patent document cannot provide a solution to the problem of operability when a stamp is superimposed on a background image.

  The present invention has been made in view of the above circumstances, and a display device, a display control method, and a display capable of improving operability during an editing operation in which one of overlapping images is enlarged / reduced by a touch operation. It is an object to provide a control program.

For the subsequent scaling operation, the display of the first image layer is kept at the same size, while the display of the second image layer is the same as the scaling of the first image. direction Display control apparatus characterized by scaling in the opposite direction.
(2) The image editing means enlarges the first image to a predetermined size with respect to the enlargement operation of the first image by the user, and then reduces the second image with respect to the subsequent enlargement operation. In such a case, the display control apparatus according to item 1, wherein the second image is reduced around the display area of the second image. (3) The image editing means reduces the first image to a predetermined size in response to the user's reduction operation of the first image, and then enlarges the second image in response to the subsequent reduction operation. In such a case, the display control device according to item 1, wherein the first image is enlarged around the position of the first image.
(4) The display control device according to any one of items 1 to 3, wherein the predetermined size is set in advance.
(5) When the first image is reduced on the preview screen at the time of printing, the image editing unit is set such that the limit of the reduction magnification of the first image differs according to the image quality setting at the time of printing. 2. The display control device according to item 1 above.
(6) When the first image is reduced in the preview screen at the time of transmission, the image editing means is set to have a limit of the reduction ratio of the first image depending on the resolution at the time of transmission. 2. The display control device according to item 1.
(7) A display control method that is executed by a display control device that includes a display unit that includes a touch panel that can perform a multi-touch operation and that can display a preview of an output image, the preview of the display unit When the first image in the first layer and the second image in the second layer in which the first image is superimposed are displayed on the screen, scaling is performed by the user's touch operation on each image layer. An image editing step for performing editing, and in the image editing step, when a scaling operation in the enlargement direction or the reduction direction by the user is continuously performed on the first image, The first image is scaled to a predetermined size, and for subsequent scaling operations, the display of the layer of the first image is kept as it is. The display control method characterized by the direction of the zooming of the second layer display the first image of the image scaling in the opposite direction.
(8) The screen is composed of a touch panel that can perform a multi-touch operation, and the computer of the display control device having display means capable of displaying a preview of the output image is displayed on the preview screen of the display means in the first layer. When the second image in the second layer in which the first image and the first image are superimposed is displayed, an image editing step for performing scaling editing on the layer of each image by a user's touch operation In the image editing step, when the scaling operation in the enlargement direction or the reduction direction by the user is continuously performed on the first image in the image editing step, the first image is set to a predetermined value. For the subsequent scaling operation, the display of the layer of the first image is maintained as it is, while the second image is displayed. Display control program for executing a process of zooming in the opposite direction to the direction of zooming the displayed first image layer of.

  According to the invention described in (1) above, in a state where the first image in the first layer and the second image in the second layer in which the first image is superimposed are displayed on the preview screen, When the scaling operation by the user in either the enlargement direction or the reduction direction is continuously performed on the first image, the first image is scaled to a predetermined size, For subsequent scaling operations, the display of the first image layer is kept as it is, while the display of the second image layer is the direction of scaling of the first image. Since scaling is performed in the reverse direction, the first image is relatively scaled relatively.

  In other words, when the scaling operation is continuously performed in either the enlargement direction or the reduction direction with respect to the first image, the first image that has been excessively enlarged or reduced can be reduced or enlarged again and operated. Therefore, after the entire image including the first image is temporarily reduced or enlarged, the adjustment work such as switching the operation target to the first image again and performing the enlargement or reduction operation becomes unnecessary, and the first image is changed. The operability at the time of zooming operation is improved, and the editing operation can be speeded up.

  According to the invention described in (2) above, the first image is enlarged to a predetermined size in response to the enlargement operation of the first image by the user, and then the second image is applied to the subsequent enlargement operation. Is reduced around the area where the second image is displayed, the relative positional relationship of the enlarged first image with respect to the second image becomes easy to understand, and the position adjustment can be performed. It becomes easy to do.

  According to the invention described in (3) above, the first image is reduced to a predetermined size in response to the user's reduction operation of the first image, and then the second image is applied to the subsequent reduction operation. Is enlarged around the position of the first image, the second image is enlarged while maintaining the positional relationship between the first image and the second image. Position adjustment becomes easy.

  According to the invention described in item (4), the first image is scaled until it reaches a predetermined size.

  According to the invention described in item (5) above, when the first image is reduced on the preview screen at the time of printing, the limit of the reduction ratio of the first image differs according to the image quality setting at the time of printing. Since it is set, a good print result according to the image quality setting can be obtained.

  According to the invention described in the preceding item (6), when the first image is reduced on the preview screen at the time of transmission, the limit of the reduction ratio of the first image is set differently according to the resolution at the time of transmission. Therefore, a good transmission result according to the image quality setting can be obtained.

According to the invention described in item (7), when the scaling operation is continuously performed in the enlargement direction or the reduction direction with respect to the first image, the first image that is excessively enlarged or reduced is used. In order to reduce or enlarge the image again and to enable the operation, the entire image including the first image is temporarily reduced or enlarged, and then the operation target is switched to the first image again and the enlargement or reduction operation is performed. This eliminates the need for work, improves the operability when scaling the first image, and speeds up the editing work.

  According to the invention described in (8) above, in a state where the first image in the first layer and the second image in the second layer in which the first image is superimposed are displayed on the preview screen, When the scaling operation by the user in either the enlargement direction or the reduction direction is continuously performed on the first image, the first image is scaled to a predetermined size, For subsequent scaling operations, the display of the first image layer is kept as it is, while the display of the second image layer is the direction of scaling of the first image.

  4, the preview screen 200 includes a title frame 201, an image display area 202, an “image operation” button 204, a “stamp” button 205, various stamps 206, a “cancel” button 207, and “execute”. ”Button 208 and the like are displayed.

  The title frame 201 is a frame for displaying a title related to the image content displayed in the image display area 202. In this figure, “Preview display” is displayed corresponding to the preview image 203 at the time of printing. Yes.

  A print preview image 203 is displayed in the image display area 202. In this embodiment, a stamp 206 is superimposed on the preview image 203 as an additional image. Note that the preview image 203 and the stamp 206 are displayed in different layers, and the stamp 206 is added to the preview image 203 by overlapping these layers.

  The “image operation” button 204 is operated when enlarging / reducing or scrolling the entire image including the preview image 203 and the stamp 206. Specifically, after the “image operation” button 204 is pressed, the image display area 202 is touched to enlarge, reduce, or scroll the display range of the preview image 203. At this time, if the stamp 206 is arranged, the enlargement, reduction, and scrolling are performed together with the operation on the preview image 203.

  The “stamp” button 205 is used when the user adds the stamp 206 as the first image on the preview image (background image) 203 as the second image, or enlarges / reduces the added stamp 206. used. That is, when the user presses the “stamp” button 205, various stamps 206 are displayed, and the stamp selected by the user is touched and dragged to move to a predetermined position of the image 203 and dropped at that position. As a result, the image is superimposed on the image 203. In this state, by pressing the “stamp” button 205 and touching the image display area 202, the stamp 206 can be enlarged / reduced or moved.

  When the user continues the enlargement or reduction operation on the stamp 206 with the stamp 206 added to the preview image 203, the control unit 11 enlarges or reduces the stamp 206 until it reaches a predetermined size. After the predetermined size is reached, even if the enlargement or reduction operation is continued on the stamp 206, the stamp 206 is held at the same size, and thereafter, the preview image 203 is scaled. The direction is reduced or enlarged in a direction opposite to the direction of.

  Further, in this embodiment, after the stamp 206 is enlarged to a predetermined size, when the display of the preview image 203 is reduced for subsequent enlargement operations, the reduction is performed with the preview image 203 as a center. On the contrary, after the stamp 206 is reduced to a predetermined size, when the display of the preview image 203 is enlarged for the subsequent reduction operation, the stamp 206 is enlarged around the position of the stamp 206. Yes.

  The “cancel” button 207 is a button for canceling the preview display, and the “execute” button 208 is a button for outputting the image displayed in the image display area 202.

  FIG. 5 is an explanatory diagram of an internal structure when a touch operation is performed on the image 203 and the stamp 206 in the display area 202.

  In FIG. 5, the image 203 displayed in the display area 202 and the stamp 206 as an additional image to be overlaid at a predetermined position of the image 203 have different layer structures (V1, V2) as described above. By designating the layer V1 (V2), the stamp 206 (image 203) can be enlarged / reduced.

  By designating both the layer V1 of the stamp 206 and the layer V2 of the image 203, the stamp 206 and the preview image 203 can be operated.

  FIG. 6 is a flowchart showing the flow of the enlargement / reduction operation for the stamp 206. This process is executed by the CPU of the control unit 11 operating according to an operation program recorded on a recording medium such as the ROM 12.

  In FIG. 6, in step S501, it is determined whether or not the operation by the user is an enlargement operation on the stamp 206. If it is not an enlargement operation on the stamp 206 (NO in step S501), the process proceeds to step S505.

  If it is an enlargement operation on the stamp 206 (YES in step S501), in step S502, it is determined whether or not the stamp 206 that has been enlarged has reached a predetermined size, and the enlarged display of the stamp 206 has a predetermined magnification. If not reached (NO in step S502), the enlargement of the stamp 206 is further continued in step S503.

  When the enlarged display of the stamp 206 reaches a predetermined size (YES in step S502), the preview image 202 is reduced in step S504.

  In step S505, it is determined whether or not the operation by the user is a reduction operation for the stamp 206. If the operation is not a reduction operation for the stamp 206 (NO in step S505), the stamp 206 is moved in step S509.

  If it is a reduction operation for the stamp 206 (YES in step S505), in step S506, it is determined whether or not the stamp 206 subjected to the reduction operation has reached a predetermined size. If the reduced display of the stamp 206 has not reached the predetermined size (NO in step S506), the stamp 206 is reduced in step S508. On the other hand, when the reduced display of the stamp 206 reaches a predetermined size (YES in step S506), the preview image 202 is enlarged in step S507.

  Each time a scaling operation is performed on the stamp 206, the routine according to this flowchart is repeated.

  In this way, when the preview image 203 and the stamp 206 are displayed so as to overlap each other, a scaling operation by the user in either the enlargement direction or the reduction direction is continuously performed on the stamp 206. , The size of the stamp 206 is changed to a predetermined size, and for subsequent scaling operations, the display of the stamp 206 is maintained as it is, while the preview image 203 is displayed in the first image. Since the magnification is changed in a direction opposite to the direction of magnification, the stamp 206 is relatively further magnified.

  In other words, when the scaling operation is continuously performed in either the enlargement direction or the reduction direction with respect to the stamp 206, the stamp 206 that has been excessively enlarged or reduced is reduced or enlarged again so that the stamp 206 can be operated. Adjustment work such as once reducing or enlarging the entire image including the stamp and then switching the operation target to the stamp 206 again to perform enlargement or reduction operation becomes unnecessary, and the operability when scaling the stamp 206 is improved. Therefore, it is possible to speed up the editing work.

  The predetermined size for stopping the enlargement or reduction of the stamp 206 is set in advance. For example, when the stamp 206 is enlarged, the size corresponding to 1/4 of the area of the display area 202 is set as the limit of the enlargement magnification, and when the stamp 206 is reduced, it corresponds to 1/16 of the area of the display area 202. The size to be used may be the limit of the reduction ratio. Note that the user may arbitrarily set the predetermined size.

  7A to 7D are explanatory diagrams of the enlargement operation for the stamp 206. FIG.

  In FIG. 7A, the user moves the stamp 206 to a predetermined position on the image 203 in the image display area 202 in the preview display. In FIG. 7A, the preview image 203 is enlarged and only a part thereof is displayed in the display area 202.

  In this state, the user performs an enlargement operation on the stamp 206 as shown in FIG. Here, the stamp 206 is enlarged by an operation of widening the interval between two fingers touched by the user.

By continuing this enlargement operation, the enlarged display of the stamp 206 reaches a predetermined size. If the enlargement operation is continued from this point, the enlargement of the stamp 206 is stopped at that point and held at the size at that point, while the preview image 203 is displayed as shown in FIG. to shrink. As a result, the stamp 206 is relatively enlarged, the positional relationship between the stamps 206 can be easily grasped, and editing workability is improved. Note that the preview image 203 is preferably reduced around the display area of the preview image 203. As a result, the relative positional relationship of the enlarged stamp 206 with respect to the preview image 202 can be easily understood, and the position can be easily adjusted.

  When the stamp 206 is relatively enlarged to a desired size, if the user touches the stamp 206 and moves it to a predetermined position shown in FIG. 7D by a drag operation, the editing operation of the stamp 206 is completed. .

  8A to 8D are explanatory diagrams of the reduction operation for the stamp 206. FIG.

  FIG. 8A shows an image display area 202 in preview display, and the entire preview image 203 is displayed in the display area 202. In this state, the user touches the stamp 206, moves it by a drag operation, and drops it at a predetermined position, thereby superimposing the stamp 206 on the preview image 203.

  In this state, the user performs a reduction operation on the stamp 206 as shown in FIG. Here, the stamp 206 is reduced by an operation in which the user narrows the interval between two fingers touching the stamp 206.

  By continuing this reduction operation, the reduced display of the stamp 206 reaches a predetermined size. Even if the further reduction operation is continued from this time point, the reduction of the stamp 206 is stopped at that time, and the size at that time is held, while the preview image 203 is enlarged as shown in FIG. . As a result, the stamp 206 is relatively reduced, and it becomes easy to grasp the mutual positional relationship.

  Here, the display area 202 when the preview image 203 is enlarged is enlarged around the position of the stamp 206, and the display position of the stamp 206 moves to the center of the display area 202 according to the enlargement ratio. Thus, since the preview image 203 is enlarged around the position of the stamp 206, the position of the stamp 206 can be easily adjusted.

  When the stamp 206 is relatively reduced to a desired size, as shown in FIG. 8D, the user moves the stamp 206 to a predetermined position W in the display area 202, and the editing operation of the stamp 206 is completed. To do.

  FIGS. 9A and 9B are examples in which, in the preview image 203 at the time of printing or transmission, when the stamp 206 is reduced, the reduction magnification can be changed to a different one depending on the image quality setting at the time of printing or transmission. It is explanatory drawing of.

  For example, it is assumed that two settings of “setting 1: setting that makes the image quality rough by high-speed printing” and “setting 2: setting that makes the image quality fine by low-speed printing” have been made. FIG. 9A shows a display area to which “Setting 1” is applied, and FIG. 9B shows a display area to which “Setting 2” is applied.

  Here, in the case of “setting 1”, if the stamp 206 is excessively reduced, the stamp 206 may be crushed and may not be discriminated in the print result. Reduce the stamp 206 so that it does not shrink too much.

As a result of adding the stamp 206 to the image 203 and performing a reduction operation, when the reduction magnification limit is reached, the reduction of the stamp 206 and the enlargement of the preview image 203 are not performed even if the reduction operation is performed. Keep it. Note that when the limit of the reduction magnification is reached, the size of the stamp 206 may be left as it is, and the preview image 203 may be enlarged. In this case, the limit of the enlargement magnification in the case of “Setting 2” is set to “Setting”. It may be set smaller than the case of “1”.

  In either case, the display of FIG. 9B to which “setting 2” capable of fine printing is applied can be further reduced as compared with the display of FIG. 9A to which “setting 1” is applied. It becomes.

  Similarly, if there are two settings for transmission, “Setting 3: Setting for transmission with small size but low resolution” and “Setting 4: Setting for transmission with large size but high resolution” To do.

  Here, in the case of “setting 3”, if the stamp 206 is excessively reduced, the stamp 206 may be crushed and may not be discriminated in the transmission result. It is preferable to make it small so that the stamp 206 is not excessively reduced.
