  However, in the technique disclosed in Patent Document 1, when the aspect ratio is fixed, the trimming frame is limited by the aspect ratio of the layout frame, and an arbitrary region of the image cannot be selected. There is a problem. Further, when the restriction on the aspect ratio is released, a blank space is generated between the layout frame and the image, or the image is arranged in a state of being extended in one direction. In addition, when the sizes of the trimming frame and the layout frame are different, the area designated by the trimming frame is displayed enlarged or reduced. For this reason, for example, when the trimming frame is smaller than the layout frame, the image is enlarged, so that the image quality is degraded. Conversely, when the trimming frame is larger than the layout frame, there is a problem that the image is crushed because the image is reduced.

  The present invention has been made in view of the above-described circumstances, and provides an image processing apparatus, an image processing method, and an image processing program in which an image is arbitrarily adjusted and the image quality does not change before and after the adjustment. Objective.

In this example, a CD (Compact Disk) / DVD (Digital Versatile Disk) publisher 30 and a digital camera 40 are connected to the I / F 16 of the image processing apparatus 10.

  Here, the CPU 11 executes various arithmetic processes in accordance with programs stored in the HDD 14 and the ROM 12 and controls each part of the apparatus. The ROM 12 is a semiconductor memory that stores programs executed by the CPU 11 and other data. The RAM 13 is a semiconductor memory that temporarily stores programs and data to be executed by the CPU 11. The HDD 14 is a magnetic storage device that stores a program 14 a executed by the CPU 11. In addition, the process mentioned later is performed by executing this program 14a. The image processing unit 15 executes a drawing process based on a drawing command supplied from the CPU 11, converts the obtained image into a video signal, supplies it to the display device 18, and displays it. The I / F 16 is a device that appropriately converts the data representation format when exchanging information with the CD / DVD publisher 30, the input device 19, and the digital camera 40. The bus 17 is a signal line group for mutually connecting the CPU 11, ROM 12, RAM 13, HDD 14, image processing unit 15, and I / F 16, and enabling exchange of information among them. The display device 18 is configured by, for example, a CRT (Cathode Ray Tube) monitor or an LCD (Liquid Crystal Display), and displays the video signal supplied from the image processing unit 15 on the display unit. The input device 19 is composed of, for example, a keyboard and a mouse, and generates and outputs information corresponding to a user operation.

  The CD / DVD publisher 30 prints an image that has been subjected to image processing in the image processing apparatus 10 on the printing surface (the back side of the data recording surface) of an optical disk such as a CD or DVD, and also provides predetermined data on the data recording surface. A device that records (for example, audio data, video data, or computer data). The digital camera 40 converts the light image of the subject into a corresponding image and stores it in a non-volatile memory (not shown). When the digital camera 40 is connected to the image processing apparatus 10 by a connection cable, the digital camera 40 stores the light image in the non-volatile memory. The image is supplied to the image processing apparatus 10.

Next, referring to FIG. 2, the program 14a stored in the HDD 14 shown in FIG. 1 is executed, so that the program 14a as software and the CPU 11 as hardware cooperate with each other. The functional block group to be performed will be described. As shown in FIG. 2, the functional block group 60 realized by executing the program 14a includes an image input unit 61, a central processing unit 62 (in the "region image display means" and "update means" in the claims). Corresponding), display processing unit 63, output processing unit 64, trimming processing unit 65 (corresponding to “trimming frame display means” in claims), layout processing unit 66 (corresponding to “layout frame display means” in claims), operation An information input unit 67, a layout information calculation processing unit 68 (corresponding to “updating means” in the claims), and a layout / trimming information storage unit 69 mainly exist.
Here, the image input unit 61 inputs an image from the digital camera 40, for example, via the I / F 16. The central processing unit 62 is a block that is the core of the processing of the functional block group 60, and controls other blocks so that a series of processing is appropriately executed. The display processing unit 63 displays a trimming screen and a layout screen, which will be described later, on the display device 18. The output processing unit 64 outputs the image processed by the trimming processing unit 65 and the layout processing unit 66 to the CD / DVD publisher 30 via the I / F 16. The trimming processing unit 65 designates a range of an image of a region to be laid out (hereinafter simply referred to as “region image”) in an image to be processed (hereinafter simply referred to as “target image”). Trimming processing such as designating the rotation angle of the area image is executed. The layout processing unit 66 executes a process for laying out the area image in the target image designated by the trimming processing unit 65 on the print target. The operation information input unit 67 acquires information output from the input device 19 via the I / F 16. When the trimming process is performed and the trimming frame is changed, the layout information calculation processing unit 68 calculates information for changing the layout frame corresponding to the trimming frame after the change. The layout / trimming information storage unit 69 stores information on the layout frame and the trimming frame.

(B) Description of Operation of Embodiment Next, the operation of the present embodiment will be described. In the present embodiment, the user operates the input device 19 to start a predetermined application program (an application program for performing predetermined printing on the printing surface of a CD or DVD using the CD / DVD publisher 30). When an operation is performed, the program 14a stored in the HDD 14 is executed, the function block group 60 of FIG. 2 is formed, and the processing shown in FIG. 3 is executed.
When the processing of the flowchart shown in FIG. 3 is executed, the central processing unit 62 first displays a layout screen on the display device 18 (step S10). More specifically, the central processing unit generates information for displaying a layout screen for setting an image layout on the print surface of the CD or DVD, and supplies the information to the display processing unit 63. As a result, a layout screen 80 as shown in FIG. In this display example, buttons 81 to 85 are displayed at the top of the layout screen 80, an area 87 for setting the layout is displayed below the area 87, and a CD to be printed is displayed at the approximate center of the area 87. (Or DVD) is an image 88 (hereinafter simply referred to as “CD image 88”), and an image 89 indicating a printing surface (hereinafter simply referred to as “printing surface image 89”) is an upper side (front of the paper in the depth direction). Side).
Here, the button 81 is a button operated when selecting a background image to be arranged on the print surface image 89 of the CD image 88. When this button 81 is operated, a list of background image candidates is displayed, from which a desired background image can be selected. The selected background image is arranged so as to be superimposed on the print surface image 89. The button 82 is a button operated when selecting an image to be arranged on the background image. When this button 82 is operated, a list of image candidates is displayed, and a desired image can be selected from the list. The selected image is arranged on the background image as will be described later. The button 83 is a button operated when trimming the image arranged by the button 82. When this button 83 is operated, a trimming screen 90 described later is displayed. The button 84 is a button operated when inputting characters. When this button 84 is operated, an arbitrary character string can be input at an arbitrary position of the print surface image 89. The button 85 is a button operated when an image edited on the layout screen 80 is supplied to the CD / DVD publisher 30 and printed on the printing surface of the optical disc.

  Returning to FIG. Next, the central processing unit 62 determines whether or not an operation for attaching an image to the print surface image 89 has been performed (step S11). Specifically, for example, whether or not a desired image is selected from image candidates displayed as a list by operating the button 82 and an image is arranged at a predetermined position of the print surface image 89 is determined. If it is determined and it is determined that an image pasting operation has been performed (step S11; Yes), the process proceeds to step S12. Otherwise (step S11; No), the process proceeds to step S13. For example, when the button 82 is operated, a list of images stored in the digital camera 40 is displayed, a desired image is selected from the list, and an operation for placing the image at a predetermined position on the print surface image 89 is performed. Advances to step S12.

When an operation for pasting an image is performed, the central processing unit 62 executes processing for pasting the target image on the print surface image 89 (step S12). More specifically, the central processing unit 62 reads the image selected in step S11 from, for example, the digital camera 40, executes a process for adjusting the resolution, and the like, and then synthesizes the image at the designated position on the print surface image 89. The obtained image is supplied to the display processing unit 63. As a result, information as shown in FIG. 5 is displayed on the display device 18. In this example, the image 100 is displayed so as to be superimposed on a substantially upper center portion of the print surface image 89. At this time, the central processing unit 62 generates layout information of the image 100 and stores it in the layout / trimming information storage unit 69 via the layout processing unit 66.
FIG. 6A shows an example of information stored in the layout / trimming information storage unit 69 at this time. In this example, information indicating the size and rotation angle of the layout frame is stored, “32, 24” is stored as the size of the layout frame, and “0” is stored as the rotation angle. Here, the size indicates the horizontal and vertical sizes of the image. The rotation angle indicates a rotation angle based on the original image. Thus, when an image is affixed on the print surface image 89, the size and rotation angle of the image are initially set as layout frame information. Note that the trimming frame information indicating the size and rotation angle of the trimming frame is in a blank “-” state at this time.

  Next, the central processing unit 62 refers to the information from the operation information input unit 67 and determines whether any of the images arranged on the print surface image 89 has been selected (step S13). ). In the example of FIG. 5, only one image 100 is arranged on the print surface image 89. However, when a plurality of images are arranged, any one of these is operated by operating the input device 19. If selected, it is determined that an image has been selected (step S13; Yes), and the process proceeds to step S14. Otherwise, the process returns to step S11 to repeat the same processing as described above. For example, in FIG. 5, when the pasted image 100 is selected, the process proceeds to step S14. In addition, when only one image is pasted, the image may be always selected.

Next, the central processing unit 62 instructs the layout processing unit 66 to display a layout frame (step S14). As a result, the layout processing unit 66 acquires layout frame information from the layout / trimming information storage unit 69, generates a layout frame, and supplies the generated layout frame to the central processing unit 62. The central processing unit 62 supplies the supplied layout frame to the display processing unit 63 for display. As a result, information as shown in FIG. 7 is displayed on the display device 18. In the display example of FIG. 7, a layout frame 101 is displayed around the image 100. In addition, a resize handle 102 having a rectangular shape is displayed outside the substantially central portion of each side of the layout frame 101 and outside each vertex. When the size changing handle 102 displayed outside each side is operated, the image 100 can be enlarged or reduced in the direction in which the side is moved. Further, when the size change handle 102 displayed outside each vertex is operated, the image 100 can be enlarged or reduced in the direction in which the vertex is moved.
If any of these size change handles 102 is selected and an operation for enlarging or reducing the image 100 is performed (step S15; Yes), the process proceeds to step S16, and otherwise (step S15; No). Then, the process proceeds to step S17.
For example, if the resize handle 102 displayed outside the lower right vertex of the image 100 is selected and an operation of moving to the lower right (an operation of enlarging the image 100) is made, it is determined Yes in step S15, Proceed to step S16.

In step S16, a process for deforming the layout frame 101 and the image 100 according to the operation content is executed. Specifically, the layout processing unit 66 deforms the layout frame 101 according to the moving direction of the size change handle 102 and enlarges or reduces the image 100 according to the change of the layout frame 101. Also, the layout frame information is updated according to the change of the layout frame 101. When the setting is made to fix the aspect ratio of the image 100 (the ratio between the width and the height of the image), the image 100 after the change is an image that has a constant aspect ratio with the image 100 shown in FIG. 100 is enlarged or reduced. If the setting is made so that the aspect ratio is not fixed, the image is freely enlarged or reduced.
For example, as described above, when the resize handle 102 displayed outside the lower right vertex of the image 100 is selected and an operation for enlarging the image is performed, as shown in FIG. Is enlarged and the image 100 is enlarged accordingly. Further, the layout frame information is updated according to the change of the layout frame 101. As a result, as shown in FIG. 6B, the size of the layout frame information is changed from “32, 24” to “40, 30”. If the layout frame 101 is not operated, the layout frame 101 is not changed and the process proceeds to step S17.

Subsequently, the central processing unit 62 determines whether or not an operation for displaying the trimming screen has been performed (step S17). If the operation has been performed (step S17; Yes), the process proceeds to step S18. In step S15, the same processing as described above is repeated. More specifically, when the button 83 is operated by the input device 19, the process proceeds to step S18.
In step S 18, the trimming processing unit 65 acquires trimming frame information from the layout / trimming information storage unit 69. In this case, as shown in FIG. 6B, the trimming frame information is blank. In this case, the size “32, 24” and the rotation angle “0” of the image 100 are set. To be acquired. The acquired layout frame information is stored in the layout / trimming information storage unit 69 as trimming frame information, as shown in FIG. That is, the size “32, 24” and the rotation angle “0” are stored in the layout / trimming information storage unit 69 as trimming frame information.

Subsequently, the central processing unit 62 displays a trimming screen (step S19), and displays a trimming frame based on the trimming frame information acquired in step S18 (step S20). FIG. 9 shows an example of the trimming screen 90 displayed on the display device 18 at this time. In this example, buttons 91 to 94 are displayed in the upper part of the trimming screen 90, an area 107 in which the trimmed image 110 is displayed is displayed below, and a trimming frame 120 is displayed around the trimmed image 110. ing.
Here, the button 91 is a button operated when enlarging or reducing the trimming frame 120. When this button 91 is operated, a size change handle 121 is displayed as will be described later. The button 92 is a button operated when the trimming frame 120 is rotated. When this button 92 is operated, a rotation angle change handle 131 is displayed as will be described later. The button 93 is a button operated when canceling the editing content on the trimming screen 90. The button 94 is a button that is operated when the editing content on the trimming screen 90 is reflected in the layout.

Next, the central processing unit 62 determines whether or not the trimming frame 120 has been operated (step S21). If operated (step S21; Yes), the process proceeds to step S22, and otherwise (step S21). ;) To Step S23.
Specifically, when the button 91 is operated, as shown in FIG. 10, eight resize handles 121 are displayed. If any of the resize handles 121 is selected and operated, step S22 is performed. Proceed to Alternatively, when the button 92 is operated, as will be described later with reference to FIG. 14, four rotation angle change handles 131 are displayed. Therefore, when any one of the rotation angle change handles 131 is selected and operated. Advances to step S22.
For example, after the button 91 is operated, as shown in FIG. 10, when the resize handle 121 displayed outside the center of the right side of the trimming frame 120 is operated toward the left side of the drawing, the process proceeds to step S22. move on. In FIG. 10, a broken line indicates the trimming frame 120 before the change.

  Next, the trimming processing unit 65 deforms the trimming frame 120 according to the content of the operation of the size change handle 121 or the rotation angle change handle 131 (step S22). For example, as illustrated in FIG. 10, when the size change handle 121 displayed on the outer side of the right side of the trimming frame 120 is operated toward the left side of the figure, the trimming processing unit 65 causes the trimming frame 65 to correspond to the operation amount. 120 is transformed and supplied to the display processing unit 63 via the central processing unit 62. As a result, the trimming frame 120 is displayed in a reduced state as shown in FIG.

Next, the central processing unit 62 determines whether or not an instruction to confirm trimming has been issued by the user (step S23), and when an instruction to confirm is given (step S23; Yes), the process proceeds to step S24. In other cases (step S23; No), the process returns to step S21 and the same processing as described above is repeated. More specifically, when the button 94 shown in FIG. 10 is operated, the process proceeds to step S24.
For example, as shown in FIG. 10, when the button 94 is operated with the trimming frame 120 adjusted, the process proceeds to step S24.

  Subsequently, the trimming processing unit 65 refers to the state of the trimming frame 120 at the time when the button 94 is operated, and trims the image (step S24). More specifically, the trimming processing unit 65 cuts out an area image surrounded by the trimming frame 120 in the trimmed image 110 from the original image, and supplies it to the central processing unit 62. The central processing unit 62 displays the trimmed area image supplied from the trimming processing unit 65 on the layout screen 80 displayed thereafter.

  Subsequently, the trimming processing unit 65 updates the trimming frame information stored in the layout / trimming information storage unit 69 (step S25). More specifically, in the example of FIG. 10, since the horizontal size of the trimming frame 120 is reduced, the trimming frame information size is changed from “32,24” to “20,20” as shown in FIG. 24 ".

Subsequently, the layout information calculation processing unit 68 executes a process for updating the layout frame information (step S26), returns to step S10, and repeats the same process as described above. Details of the process in step S26 will be described with reference to FIG.
When the processing of the flowchart shown in FIG. 11 is started, the following steps are executed. That is, the layout information calculation processing unit 68 applies the increase / decrease in the size of the trimming frame 120 to the layout frame information (step S50). Specifically, assuming that the size of the trimming frame before adjustment is TS1, the size of the trimming frame after adjustment is TS2, and the size of the layout frame before change is LS1, the size LS2 of the layout frame after change is LS2. = LS1 × TS2 / TS1. In the example of FIG. 10, since TS1 = (32, 24), TS2 = (20, 24), and LS1 = (40, 30), LS2 = (25, 30). In other words, the values obtained by dividing the vertical and horizontal lengths of the trimming frame by the vertical and horizontal lengths before the change are respectively converted into the vertical and horizontal lengths of the layout frame before the change. The layout frame information is changed so as to be the size of the value obtained by multiplication.

  Subsequently, the layout information calculation processing unit 68 applies the increase / decrease of the rotation angle of the trimming frame 120 to the layout frame information (step S51). Specifically, if the rotation angle of the trimming frame before adjustment is TA1, the rotation angle of the trimming frame after adjustment is TA2, and the rotation angle of the layout frame before change is LA1, the rotation angle of the layout frame after change is LA2 is obtained by LA2 = LA1 + TA2-TA1. In the example of FIG. 10, since TA1 = 0, TA2 = 0, and LA1 = 0, LA2 = 0. In other words, the value obtained by subtracting the rotation angle before the change from the rotation angle after the change of the trimming frame is added to the rotation angle of the layout frame before the change so that the rotation angle becomes the value obtained. Change layout frame information. Note that the axis serving as the reference for rotation is set at the center of the image, for example.

Subsequently, the layout information calculation processing unit 68 updates the layout frame information stored in the layout / trimming information storage unit 69 with the information on the size and rotation angle of the layout frame obtained in steps S50 and S51 (step S52). ). As a result, as shown in FIG. 6E, the size of the layout frame information is updated from “40, 30” to “25, 30”, and the rotation angle remains “0”.
In this state, when the layout screen 80 is displayed again in step S10, the image 100 becomes an image of the area selected by the trimming frame 120 as shown in FIG. Further, the layout frame 101 displayed when the image 100 is selected has the size changed in step S50 and the rotation angle changed in step S51. Note that a rectangle indicated by a broken line in the drawing indicates the contour of the image 100 and the layout frame 101 before the change, and indicates that the image 100 and the layout frame 101 are reduced by the trimming process. In this example, when the center of the layout frame 101 before the change is the origin, the layout frame 101 and the image 100 are arranged so that the origin matches the centers of the layout frame 101 and the image 100 after adjustment. Yes. Instead of arranging the center of the layout frame 101 before the change as the origin, the origin may be arranged so that the origin coincides with the upper left corner as the origin. It goes without saying that other arrangement methods (for example, a method in which the lower left corner, the upper right corner, and the lower right corner are used as the origin) may be used.

Subsequently, when the image 83 is selected again on the layout screen 80 shown in FIG. 12 and the button 83 is operated, the trimming screen 90 shown in FIG. 13 is displayed. In this display example, the trimming frame 120 has the same size as that shown in FIG. This is because the trimming frame information updated by the process of step S25 is acquired in step S18, and the trimming frame 120 is displayed in step S20.
When the button 92 is operated on such a trimming screen 90, the rotation angle change handle 131 is displayed outside each vertex of the trimming frame 120 and the rotation axis 130 is displayed as shown in FIG. . In such a trimming screen 90, for example, when an operation for rotating the trimming frame 120 around the rotation axis 130 is performed after a predetermined rotation angle change handle 131 is selected, the trimming frame 120 is as shown in FIG. Rotate to. In this figure, the broken line indicates the trimming frame 120 before rotation.
Subsequently, when the button 91 is operated on the trimming screen 90 of FIG. 14, the resize handle 121 located at the top of the drawing is selected as shown in FIG. 15, and the operation of reducing the trimming frame 120 is performed. Then, the trimming frame 120 is reduced according to the operation.

If the button 94 is operated in the state shown in FIG. 15, the image trimming process is executed, and the trimming frame information is updated in step S25. As a result, for example, as shown in FIG. 6F, the trimming frame information is changed. In this example, the size of the trimming frame information is changed from “20, 24” to “16, 20”, and the rotation angle is changed from “0” to “40”.
In step S26, the layout information calculation processing unit 68 updates the layout frame information. As a result, as shown in FIG. 6G, the size of the layout frame information is changed from “25, 30” to “20, 25”, and the rotation angle is changed from “0” to “40”. .

  Then, returning to step S10, when the layout screen 80 is displayed again, the information shown in FIG. 16 is displayed. In the display example of FIG. 16, the region of the trimmed image 110 selected on the trimming screen 90 of FIG. 15 is displayed. Further, the center of the previous layout frame 101 (layout frame 101 shown in FIG. 12) and the center of the image 100 are arranged to coincide. Note that, as described above, the image arrangement may be other than this.

  In the state shown in FIG. 16, when the button 85 is operated and printing is instructed, the central processing unit 62 displays the trimmed image 110, a background image (not shown), a character (not shown), and the like. The image generated by combining these is output to the CD / DVD publisher 30 via the output processing unit 64. As a result, the CD / DVD publisher 30 prints the supplied image on the printing surface of the optical disc (not shown). Thereby, the same information as the print surface image 89 shown in FIG. 16 is printed on the print surface of the optical disc.

When the image 100 is selected on the layout screen 80 shown in FIG. 16 and an operation for changing the layout frame 101 is performed, the layout frame information is updated according to the operation content. For example, assume that an operation for enlarging the size of the layout frame 101 from “20, 25” to “32, 40” is performed on the layout screen 80 shown in FIG. Then, the layout frame information is changed to “32, 40”, and the trimming frame information is unchanged as “16, 20”. As a result, the area of the image cut out by the trimming frame 120 shown in FIG. 15 is displayed in the layout frame 101 having a size larger than that in FIG.
In such a state, when the trimming frame 120 is operated, a new layout frame 101 is calculated by the above-described calculation formula. For example, when the size of the trimming frame 120 is changed from “16, 20” to “24, 30”, the layout frame size is changed from “32, 40” to “48, 60” based on the above-described formula. Be changed.
In the present example, the image 100 is enlarged while maintaining the aspect ratio of the image 100. However, when the aspect ratio is ignored and enlarged, and the aspect ratio is not fixed. The image 100 is enlarged without considering the aspect ratio. That is, the image 100 is stretched in one direction. On the other hand, when the aspect ratio is ignored and enlarged, and the aspect ratio is set to be fixed, the layout frame 101 that is enlarged while ignoring the aspect ratio is maximized while maintaining the aspect ratio. In this state, the enlarged image 100 is placed.

In the above embodiment, when the trimming frame 120 is changed, the layout frame 101 is updated in accordance with the changed content, and the area displayed in the layout frame 101 is designated by the new trimming frame 120. It was made to update with the area image. As a result, the size of the layout frame 101 changes in accordance with the size of the trimming frame 120, so that the image resolution is changed by enlarging or reducing the image depending on the ratio of the size of the layout frame 101 and the trimming frame 120. Can be prevented.
In addition, when the aspect ratio of the trimming frame 120 is changed, the layout frame 101 is converted in the same manner, thereby preventing an image from extending in one direction and a margin from being generated in the image. it can.

  Further, when the trimming frame 120 is rotated, the layout frame 101 is also rotated accordingly. As a result, the rotation angle of the region image specified by the trimming frame 120 and the rotation angle of the region image arranged in the layout frame 101 can be made the same, so that the region image is arranged at a target angle. Can do.

  Further, since the trimming frame 120 is not limited by the aspect ratio of the layout frame 101, an arbitrary area can be selected by the trimming frame 120. Thereby, the freedom degree of a user's selection can be improved.

(C) Modified Embodiment The above-described embodiment is merely an aspect of the present invention, and it is needless to say that modifications and applications can be arbitrarily made within the scope of the present invention.
For example, in the above-described embodiment, the case where an image is printed on a CD or a DVD has been described as an example. However, in addition to this, for example, printing is performed on paper or other media. Also good. Further, instead of printing on a print medium, for example, it can be stored as image data and displayed on a display device.

In the above description, the case where the size and the rotation angle of the trimming frame 120 are changed has been described as an example. However, the shape of the trimming frame 120 may be changed in addition to these. For example, when the trimming frame 120 having a rectangular shape is changed to a trapezoidal shape or a parallelogram shape, the layout frame 101 is deformed according to the deformation mode of the trimming frame 120 and specified by the trimming frame 120. The region image to be displayed may be displayed in the layout frame 101.
Further, the trimming frame 120 having a shape other than the rectangular shape may be used. For example, a triangular shape, a pentagonal or more polygonal shape, a circular shape, a star shape, a heart shape and other shapes. When the trimming frame 120 is changed to these shapes, the layout frame 101 may be changed to the same shape and the area image specified by the trimming frame 120 may be displayed in the layout frame 101.
When the size of the trimming frame 120 is changed, the size of the layout frame 101 is changed according to the ratio of the vertical and horizontal lengths of the trimming frame 120 before and after the change. Further, when the rotation angle of the trimming frame 120 is changed, the rotation angle of the layout frame 101 may be changed in accordance with the increase or decrease of the rotation angle of the trimming frame 120 before and after the change.

  In the above description, only the trimming frame 120 is rotated on the trimming screen 90. For example, the trimmed image 110 itself can be rotated as necessary. Specifically, a slider or the like may be provided, and the image may be rotated in a predetermined direction (clockwise or counterclockwise) according to the operation amount of the slider.

  In the above, the image 100 is arranged on the printing surface image 89 and the layout frame 101 corresponding to the image 100 is set. However, the layout frame 101 is set first, and a predetermined image is placed in the layout frame 101. It may be arranged. In that case, for example, it can be arranged with the aspect ratio fixed, or can be arranged with the aspect ratio not fixed. For example, in the case where the aspect ratio is fixed, the image is reduced or enlarged in the set layout frame 101 so as to be maximized with the aspect ratio fixed. If the aspect ratio is not fixed, the image size may be reduced or enlarged in accordance with the layout frame 101 for display. In such a case, on the trimming screen 90, the trimming process may be executed using the enlarged or reduced image as a trimmed image.

In the above description, only the case where the size of the image 100 is enlarged or reduced is described as an example on the layout screen 80. However, the rotation angle of the image 100 may be changed. In that case, the image 100 may be rotated in accordance with a user operation, and the rotation angle of the layout frame information may be changed.
Alternatively, the image 100 and the layout frame 101 may be rotated in accordance with a user operation, and the trimming frame 120 and the trimmed image 110 may be rotated in the same manner. According to such a method, the trimming frame 120 and the layout frame 101 can have the same rotation angle. Further, the image 100 can be rotated in an arbitrary direction in accordance with the operation of the layout frame 101.

  In the above description, in the trimming screen 90, when the trimming frame 120 is rotated, the trimming frame 120 is rotated about the rotation axis 130 present at the center of the trimming frame 120. For example, the rotation may be performed with the upper left corner, upper right corner, lower left corner, lower right corner) as axes. Alternatively, the rotation shaft 130 may be movable to any position including the region outside the trimming frame 120.

  In the above embodiment, when the trimming frame 120 is changed, the size and the rotation angle of the layout frame 101 are changed based on the above-described formulas. For example, the trimming frame 120 is changed. In such a case, the size and rotation angle of the layout frame 101 may be changed to the same value. When the size and rotation angle of the layout frame 101 are changed, the size and rotation angle of the trimming frame 120 may be changed to the same value in the same manner.

  In the above description, the case where the image processing apparatus of the present invention is applied to a personal computer has been described as an example. However, the present invention can be applied to many other devices. Specifically, for example, the present invention can be applied to a digital camera, a mobile phone, a PDA (Personal Digital Assistant), a game device, and other electronic devices.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the image processing apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Examples of the optical disc include a DVD (Digital Versatile Disk), a DVD-RAM, a CD-ROM (Compact Disk ROM), and a CD-R (Recordable) / RW (ReWritable). Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program.
