Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image editing technique, and more particularly to a technique for adjusting the composition of an image while displaying and / or printing a still image or a moving image taken by a digital still camera or a digital video camera.
[0002]
[Prior art]
A general function is to capture image data captured by a digital camera, display the image data on a display device, designate an arbitrary region of the image as a trimming region using a pointer device such as a mouse or a remote controller, and print the image. FIG. 6 shows an example of a very general trimming process. That is, in FIG. 6, the trimming frame 602 is displayed so as to overlap the image 601 before trimming, and the user specifies the desired portion of the image 601 by reducing, enlarging, rotating, and moving the trimming frame 602, finally. A trimmed image 603 having a composition desired by the user is obtained.
[0003]
On the other hand, as a conventional technique of different operation formats for obtaining a similar trimmed image, for example, as in Patent Document 1 below, a television is connected to a digital image editing apparatus in which predetermined image editing software is stored, Display the image data so that it fits the display area of the screen, then enlarge the image data to a size that exceeds the display area of the TV, and move the enlarged image data in the direction according to the instruction from the outside It is known to change image data so that it is displayed in a display area. The following Patent Document 2 applies a similar method to a digital camera, and includes a cross key for enlargement operation and a cross key for position designation.
[0004]
As another prior art, as shown in Patent Document 3 below, image data in which a person's face is copied is displayed, two predetermined locations are indicated by an instruction means, and output is based on the two specified points. A method is also known in which the face size and the enlargement / reduction ratio of an image at a position that are optimal for the paper size are obtained and the image is printed at a predetermined position.

[Problems to be solved by the invention]
However, in the trimming operation of the type shown in FIG. 6, it is easy to see which part of the original image is to be cut out in order to reduce and move the trimming frame while looking at the entire image, but it is printed in the actual print area. There is a drawback that it is difficult to grasp the impression obtained from the composition of time.
[0007]
On the other hand, the methods of Patent Document 1 and Patent Document 2 are excellent in that the composition after printing can be easily understood, but when performing trimming, the image is once enlarged and then the position is changed. In order to move, the enlargement operation and the movement operation are two steps.
[0008]
Patent Document 3 aims to make the size and position of the face suitable for the size of the paper to be printed when creating the ID photo. The point specified by the user is the vertex of the head in advance. It is determined like the tip of the chin, and its use is different from that of general snapshot angle-of-view correction.
[0009]
An object of the present invention is to provide an image editing technique capable of moving and enlarging (reducing) only by a user performing a one-step operation.
Another object of the present invention is to provide an image editing technique capable of performing trimming while grasping the composition at the time of printing.
[0010]

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
(First embodiment)
FIG. 1 shows a hardware configuration of an image editing apparatus according to first to fifth embodiments of the present invention. 101 is a CPU (central processing unit) that executes a computer software program, 102 is a ROM (read only memory) that stores the program, 103 is a RAM (random access memory) that is used when the program is executed, and 104 is a program storage Hard disk drive (HDD) 105, a storage device for storing programs and data in a medium such as a flexible disk or an MO (magneto-optical disk), and 106 for displaying program execution results and execution status A display device 107 is a memory card interface for inserting a memory card to read / write data, 108 is a mouse, 109 is a printer, and 110 is a bus.
[0013]
In the present embodiment, an image is displayed after the mouse 108 has moved using two coordinate systems, a display memory coordinate system for displaying an image on the display 106 and an image coordinate system for representing a position on the image data. The area to be cut out from the data and the enlargement ratio at the time of drawing for display on the display 106 are determined, and finally written in the display memory area.
[0014]
(Description of display memory coordinate system)
The display memory coordinate system is indicated by reference numeral 503 in FIG. With x = y = 0 as the origin, the x-axis extends to the right and the y-axis extends downward in the drawing. The image is drawn in a display area having a width cWidth and a height cHeight with the origin (0,0) as the upper left point of the image. Coordinate designation with the mouse is also performed in this display memory coordinate system. When an arbitrary point on the displayed image is dragged with the mouse, the coordinates indicated by the mouse are changed from the point (x0, y0) before the movement to the point (x1, y1) after the movement (510). Dragging is an operation to move the mouse while holding down the left mouse button. The coordinates where the left button was pressed are the points before the movement (x0, y0), and the coordinates where the left button was released are the points after the movement (x1 , y1).
[0015]
(Description of image coordinate system)
An image coordinate system, which is another coordinate system, is shown at 501 and 502 in FIG. Reference numeral 501 indicates a state before movement by dragging the mouse, and 502 indicates a state after movement. In FIG. 5, reference numeral 504 denotes an image outline, 505 and 507 denote trimming frames indicating trimming areas, and 506 and 508 denote coordinates designated by the mouse. The image coordinate system is normalized so that the x-axis length of the image outline 504 is 1. The mouse coordinate 506 in the image coordinate system corresponds to (x0, y0) in the display coordinate system, and the mouse coordinate 508 after movement corresponds to (x1, y1) in the display coordinate system. Furthermore, if you specify an arbitrary point of the image on the display and pinch it to move (drag), the point specified by the mouse on the image coordinate system is the point 506 before moving and the point after moving This means that it is unchanged at point 508. Further, the outline 504 of the image is unchanged before and after the movement, and the trimming frame moves from 505 to 507 to the left.
[0016]
For example, the user can perform trimming to configure an appropriate composition by changing the position of the main subject displayed on the display. First, the user moves the position of the main subject by moving the mouse pointer to the display coordinate system (x0, y0) where the main subject is located and dragging from the display coordinate system (x0, y0) to (x1, y1). Can be moved from the middle to the right. When the mouse pointer is moved by a drag operation, the main subject moves so as to follow the mouse pointer. Accordingly, the mouse positions 506 and 508 in the image coordinate system before and after the movement both indicate the same main subject position. In the display coordinate system, the main subject was instructed to move from (x0, y0) to (x1, y1) to the right, so in the image coordinate system, the main subject positions 506 and 508 did not change, and the trimming frame was not moved. The trimming frame 505 moves to the left to the trimming frame 507 after the movement. The enlargement ratio of the trimming frames 505 and 507 is determined so as to match the size of the display area of the display. The trimming frames 505 and 507 have the same size, and the image enlargement ratio is the same before and after the movement. Then, the upper left coordinates of the trimming frames 505 and 507 are displayed on the display so that the positions of the display coordinate system (0, 0) coincide.
[0017]
Next, the display coordinate system 403, the image coordinate system 401 before the drag movement, and the image coordinate system 402 after the drag movement in FIG. 4 will be described. In the image coordinate system 501 before movement in FIG. 5, the trimming frame 505 is inside the image outline 404, whereas in the image coordinate system 401 before movement in FIG. 4, the left end of the trimming frame 405 is in contact with the left end of the image outline 404. Is different.
[0018]
As in FIG. 5, a case will be described in which the display coordinate system (x0, y0) is moved to (x1, y1) by a mouse drag operation. As in FIG. 5, if the trimming frame 405 before moving is moved to the left, the trimming frame 405 protrudes from the image outline 404, and an area where no image data exists in the trimming frame 405 enters. Therefore, as shown in FIG. 4, the trimming frame 407 after movement is aligned with the left end of the image outline 404 so that the size of the trimming frame 407 is smaller than the trimming frame 405 before movement. Mouse positions 406 and 408 before and after movement indicate the same main subject. The images in the trimming frames 405 and 407 are enlarged to the size of the display. Therefore, the enlargement ratio of the display image in the trimming frame 407 after movement is larger than the enlargement ratio of the display image in the trimming frame 405 before movement. That is, by this trimming operation, the main subject on the display moves to the right and expands. As a result, the moving process and the expanding process can be performed by a one-step drag operation.
[0019]
As described above, when an instruction to move the trimming frame 405 is made by dragging beyond the edge of the outline 404 of the image in the direction opposite to the moving direction, the image is enlarged and displayed according to the amount of movement exceeding the trimming frame 405. Further, the image of the point before movement designated by the drag is displayed so as to move to the point after movement regardless of the enlargement ratio. Specifically, the image of the point before the movement that has been instructed is moved to the point after the movement, and the movement amount and the enlargement ratio of the image are calculated and displayed so that there is no blank in the trimming frame.
[0020]
FIG. 2 is a flowchart showing the processing of the image editing method according to the first embodiment of the present invention. The first embodiment of the present invention will be described below according to the flowchart. When the mouse is dragged, the following processing is started.
[0021]
In step S201, the position (Ix, Iy), width Iw, and height Ih of the clipping frame (trimming frame) on the image coordinate system at that time are obtained. That is, as shown in FIGS. 4 and 5, the position of the upper left point of the image outline 404, 504 is (0, 0), the position of the upper left point of the clipping frame 405, 505 in the image coordinate system is (Ix, Iy), and clipping is performed. The width and height of the frames 405 and 505 are substituted into (Iw, Ih).
[0022]
In step S202, the position coordinates of the mouse before the movement start in the display memory coordinate system are acquired and substituted into (x0, y0).
[0023]
In step S203, a predetermined time waiting is set in order to capture the movement of the mouse.
[0024]
In step S204, the position coordinates of the mouse after movement in the display memory coordinate system are acquired and substituted into (x1, y1).
[0025]
In step S205, as shown in FIGS. 4 and 5, the position (x ′, y ′), width w ′, and height h ′ of the new clipping frames 407 and 507 are obtained and the enlargement ratio is obtained. A method of calculating x, 'y', w ', h' will be described later.
[0026]
In step S206, the images in the new clipping frames 407 and 507 designated by x, 'y', w ', and h' obtained in step S205 are read and drawn in the display memory coordinate system at the obtained enlargement ratio. Thereby, an image is displayed on the display.
[0027]
In step S207, it is determined whether or not the mouse drag has ended. If it has ended, the process ends. If not, the process returns to step S201 to repeat the same process. When the processing is completed, the trimmed image is printed or saved. The clipping frame is an image print area indicating an image area to be printed. When the user instructs printing of the image displayed in the clipping frame, the image in the clipping frame is printed.
[0028]
By performing the above image editing process, the main subject is moved and / or enlarged so that it follows the mouse pointer during the drag operation and is displayed at any time, so trimming while grasping the composition at the time of printing Can do.
[0029]
Next, a calculation method of the position (x ′, y ′), width w ′, and height h ′ of the clipping frame in step S205 will be described. Here, for ease of explanation, a case will be described in which the movement of the mouse is moved laterally from left to right, that is, in the positive direction of the X axis. The same method can be used for the reverse direction, the vertical direction, and the diagonal direction.
[0030]
The method for obtaining the position, width and height of a new clipping frame is considered in two cases in the initial state. One is a case where the clipping frame 405 is in contact with the outline 404 of the image as indicated by 401 in FIG. 4, that is, when x = 0. The other is the case where the clipping frame 505 is not in contact with the outline 504 of the image, ie, x ≠ 0, as indicated by reference numeral 501 in FIG.
[0031]
In the case of x = 0 in FIG.
x '= 0 (because it touches the left edge of the image) ------- (1)
w '= w × x0 / x1 -------- (2)
h '= h × w' / w --------- (3)
y '= y + h × y0 / cHeight-h' × y1 / cHeight ---- (4)
[0032]
In the case of x ≠ 0 in FIG.
w '= w -------------- (5)
x '= x- (x1-x0) × w / cWidth ------ (6)
y '= y
h '= h
[0033]
(Effects of the first embodiment)
According to the first embodiment, when an arbitrary point of the image displayed in the image display area of the image data is instructed to move, the moving amount and the enlargement ratio of the image are calculated according to the moving instruction, and the calculation is performed. A predetermined area of the image data is displayed in the image display area according to the moving amount and enlargement ratio of the image.
According to this embodiment, while displaying only the print area in the trimming frame, when you specify an arbitrary part of the image with a mouse or pen and drag it while holding it, the image is enlarged as necessary The image can be moved to a desired position. For example, when it is desired to bring a person to the right end by trimming an image in which a person is shown in the center, it has been necessary to zoom in and then move, but according to this embodiment, the position to be arranged By simply dragging the person portion, the person moves and the image is enlarged as necessary, so that it is possible to obtain an image with a preferable composition in one operation.
[0034]
(Second Embodiment)
FIG. 7 is a flowchart showing the processing of the image editing method according to the second embodiment of the present invention. The second embodiment of the present invention will be described below according to the flowchart. When the mouse is dragged, the following processing is started.
[0035]
In step S701, the current position (Ix, Iy), width Iw, and height Ih of the clipping frame (trimming frame) on the image coordinate system are obtained. Similarly to the above, the position of the upper left point of the clipping frame in the image coordinate system is substituted into (Ix, Iy), and the width and height of the clipping frame are substituted into (Iw, Ih).
[0036]
In step S702, the position coordinates of the mouse before the start of movement in the display memory coordinate system are acquired and substituted into (x0, y0).
[0037]
In step S703, a predetermined time waiting is set in order to capture the movement of the mouse.
[0038]
In step S704, the position coordinate of the mouse after movement in the display memory coordinate system is acquired and substituted into (x1, y1).
[0039]
In step S705, the position (x ′, y ′), width w ′, and height h ′ of the new clipping frame are obtained, and the enlargement ratio is obtained. The calculation method of x, 'y', w ', h' is basically the same as in the first embodiment. Details thereof will be described later.
[0040]
In step S706, the image in the new clipping frame specified by x, 'y', w ', h' obtained in step S705 is read and drawn in the display memory coordinate system at the obtained enlargement ratio. Thereby, an image is displayed on the display.
[0041]
In step S707, it is determined whether or not the dragging of the mouse has ended. If it has ended, the process ends. If not, the process returns to step S703. This return destination is a clear difference from the first embodiment. In the first embodiment, the process returns to the first step S201.
[0042]
In step S705 of the second embodiment (FIG. 7), the new clipping frame is always obtained as the initial unchanging clipping frame information Ix, Iy, Iw, Ih and the mouse position at the start of the movement instruction acquired in steps S701 and S702. Calculate using (x0, y0). On the other hand, in step S205 of the first embodiment (FIG. 2), the new clipping frame changes the clipping frame information Ix, Iy, Iw, which changes during the drag (movement instruction) acquired in steps S201 and S202. Calculate using Ih and mouse position (x0, y0).
[0043]
As shown in FIG. 4, the first and second embodiments are the same in that the clip changes from the clipping frame 405 to the clipping frame 407 when dragging from the display coordinates (x0, y0) to (x1, y1). is there. Thereafter, the first and second embodiments are different when a drag operation for returning from the display coordinates (x1, y1) to (x0, y0) is performed.
[0044]
In the first embodiment, as shown in FIG. 9, when the display coordinate (x1, y1) is dragged to (x0, y0) (910), the trimming frame 905 changes to the trimming frame 907. That is, only the dragged main subject moves to the left without changing the enlargement ratio (image size).
[0045]
In contrast, the second embodiment returns from the trimming frame 407 in FIG. 4 to the original trimming frame 405. That is, when the display coordinate system is dragged in the order of (x0, y0) → (x1, y1) → (x0, y0), the trimming frame 405 → the trimming frame 407 → the trimming frame 405 changes. The second embodiment is reversible, and the first embodiment is not reversible.
[0046]
(Effect of 2nd Embodiment)
According to this embodiment, while displaying only the print area in the trimming frame, when you specify an arbitrary part of the image with a mouse or pen and drag it while holding it, the image is enlarged as necessary Thus, not only can the image be moved to a desired position, but also when the moving direction of the mouse is reversed during a series of drags, the image is reduced with the drag start state as a limit. Thereby, when the mouse is moved more than necessary and the image becomes too large, the size of the original image can be brought close by moving the mouse in the reverse direction.
[0047]
(Third embodiment)
FIG. 3 is a flowchart showing the processing of the image editing method according to the third embodiment of the present invention. The third embodiment of the present invention will be described below according to the flowchart. When a mouse drag operation is performed, the following processing starts.
[0048]
In step S301, the position, width, and height of the clipping frame (trimming frame) on the image coordinate system in the initial state are obtained. The position of the upper left point of the clipping frame in the image coordinate system is (Isx, Isy), and the width and height of the clipping frame are (Isw, Ish).
[0049]
In step S302, the mouse position coordinates (sx0, sy0) before the movement start in the display memory coordinate system are acquired.
[0050]
In step S303, the position, width, and height of the clipping frame on the image coordinate system at that time are obtained. That is, the position of the upper left point of the clipping frame in the image coordinate system is substituted into (Ix, Iy), and the width and height of the clipping frame are substituted into (Iw, Ih).
[0051]
In step S304, the position coordinates of the mouse before starting movement in the display memory coordinate system are acquired and substituted into (x0, y0).
[0052]
In step S305, a predetermined waiting time is set in order to capture the movement of the mouse.
[0053]
In step S306, the position coordinates of the mouse after movement in the display memory coordinate system are acquired and substituted into (x1, y1).
[0054]
In step S307, a new clipping frame position (x ', y'), width w ', and height h' are obtained. A method for calculating x, 'y', w ', h' will be described later. However, the enlargement ratio is not calculated.
[0055]
In step S308, the image in the new clipping frame specified by x, 'y', w ', h' obtained in step S307 is read and drawn in the display memory coordinate system. The difference from the first embodiment is that the image is displayed on the display without performing the enlargement process. This display will be described later with reference to FIG.
[0056]
In step S309, it is determined whether or not the mouse drag is finished. If finished, the process proceeds to step S310, and if not finished, the process returns to step S303.
[0057]
In step S310, the position (x ′, y ′), width w ′, and height h ′ of the new clipping frame are obtained, and the enlargement ratio is obtained. The calculation method of x, 'y', w ', h' is the same as in the first and second embodiments. At this time, as the original clipping region, the information (Isx, Isy, Isw, Ish) of the clipping region in the initial state and the information (sx0, sy0) of the mouse position acquired in steps S301 and S302 are used.
[0058]
In step S311, the image in the new clipping frame specified by x, 'y', w ', h' obtained in step S310 is read and drawn in the display memory coordinate system at the obtained enlargement ratio. This display is the same as the display method shown in FIGS.
[0059]
FIG. 8 shows the display method in step S308 described above. A case where the user moves the mouse pointer in the display coordinate system 803 while dragging from the display coordinates (x0, y0) to (x1, y1) will be described. At this time, the user is in the drag operation and keeps pressing the left button. The image coordinate system 801 before movement indicates the trimming frame 805 and the mouse position 806 acquired in steps S303 and S304. The image coordinate system 802 after movement shows the mouse position 808 and the trimming frame 807 acquired in steps S306 and S307. That is, in step S308 during the drag operation, only the movement of the image according to the movement of the mouse is performed, and the enlargement (reduction) is not performed. The moved trimming frame 807 protrudes from the outline 804 of the image and includes an area without image data. The area without image data is displayed on the display as white data, for example. Then, in step S311 after the drag operation is completed, the image is moved and enlarged according to the drag as in the first and second embodiments.
[0060]
Next, a method for calculating the image coordinate system 802 after the movement in step S307 will be described. Specifically, a calculation method of the position (x ′, y ′), width w ′, and height h ′ of the trimming frame 807 is shown. Here, for ease of explanation, a case will be described in which the movement of the mouse is moved laterally from left to right, that is, in the positive direction of the X axis. The same method can be used for the reverse direction, the vertical direction, and the diagonal direction.
[0061]
x '= x0-x1
y '= y
w '= w
h '= h
[0062]
(Effect of the third embodiment)
According to the third embodiment, image data is displayed without changing the image size according to the calculated movement amount of the image during the movement instruction by dragging, and the calculated image is dropped when the movement instruction ends by dragging. The image data is displayed according to the movement amount and the enlargement ratio.
According to the present embodiment, when only a print area within the trimming frame is displayed and an arbitrary part of the image is designated with a mouse or a pen and dragged while holding the image, the image size is kept during the dragging. Move invariantly and drop at the desired position, the image will be enlarged as needed. This has the effect that the operation of enlarging after moving the image is easy to understand.
[0063]
(Fourth embodiment)
The above embodiment has been described using two coordinate systems, the display memory coordinate system and the image coordinate system for expressing the position on the image data. In the fourth embodiment, the position on the image data is used. A method for reducing the trimming frame and moving the trimming frame at the same time when trimming is performed only in the image coordinate system for expressing the above will be described.
[0064]
In FIG. 10, a trimming frame 1001 is displayed over the image, and the user operates the trimming frame to determine the trimming position of the image. At this time, if the portion of the trimming frame is dragged, the size of the trimming frame changes and the trimming frame can be reduced. The trimming frame can be moved by dragging the inside of the trimming frame. Therefore, when performing reduction and movement, it is a two-step operation.
[0065]
Therefore, in the present embodiment, a method will be described in which reduction and movement can be performed simultaneously by dragging the dividing point area 1002 indicated by the diagonal stripe pattern of FIG.
[0066]
Reference numeral 1101 in FIG. 11 represents a trimming area 1104 and a dividing point area 1105 in the entire image 1103 before the trimming operation is performed. Reference numeral 1102 denotes a trimming area 1107 and a dividing point area 1108 in the entire image 1106 after the trimming operation.
[0067]
In the trimming area 1104 before the trimming operation, the position of the upper left corner is (x, y), the width is w, and the height is h. In the trimming area 1107 after the trimming operation, the position of the upper left corner is (x ′, y ′), the width is w ′, and the height is h ′.
[0068]
Also, the drag start coordinates in the division point area before the trimming operation are (x0, y0), and the drag end coordinates in the division point area after the trimming operation are (x1, y1).
[0069]
During the drag operation, as a user, the coordinate position in the dividing point area does not change, and the size and location of the frame outside the dividing area move. That is, the position and enlargement ratio (including reduction) of the trimming area are calculated so that the positions of the points before and after the movement are fixed points on the image data and no blank is formed in the trimming area.
[0070]
Here, the operation when the dividing point area 1105 is dragged will be described with reference to the flowchart of FIG.
[0071]
After the start of dragging, in step S1201, the position (x0, y0) of the mouse in the image coordinate system is acquired.
[0072]
In step S1202, a predetermined time waiting is set in order to capture the movement of the mouse.
[0073]
In step S1203, the position (x1, y1) of the mouse after movement in the image coordinate system is acquired.
[0074]
In step S1204, new trimming area coordinates (x ′, y ′), width (w ′), and height (h ′) are obtained. That is, the position and enlargement ratio (including reduction) of the new trimming area are calculated. A method of calculating x, 'y', w ', h' will be described later.
[0075]
In step S1205, a new trimming area specified by x, 'y', w ', h' obtained in step S1204 is drawn.
[0076]
In step S1206, it is determined whether or not the drag of the mouse has ended. If it has ended, the process ends. If it has not ended, the process returns to step S1201. In other words, the position and enlargement ratio of the new trimming area are calculated and drawn during and after the movement.
[0077]
Next, a calculation method of the frame position (x ′, y ′), width (w ′), and height (h ′) of the trimming area in step S1204 will be described.
[0078]
Here, for ease of explanation, a case will be described in which the movement of the mouse is moved laterally from left to right, that is, in the positive direction of the X axis. The same method can be used for the reverse direction, the vertical direction, and the diagonal direction.
[0079]
The method for obtaining the position, width, and height of a new trimming frame is considered in two cases in the initial state. One is the case 1101 where the trimming frame is in contact with the outline of the image, that is, x = 0, as indicated by 1101 in FIG. The other is a case where the trimming frame is not in contact with the outline of the image, that is, when x ≠ 0.
[0080]
When x = 0, it is obtained by the following equation.
x '= 0 (because it touches the left edge of the image) ------- (7)
w '= w × x0 / x1 -------- (8)
h '= h × w' / w --------- (9)
y '= y + h × y0 / cHeight-h' × y1 / cHeight ---- (10)
[0081]
On the other hand, when x ≠ 0, the size of the trimming area does not change and is only moved, and therefore is obtained by the following equation.
w '= w -------------- (11)
x '= x- (x1-x0) × w / cWidth ------ (12)
y '= y
h '= h
[0082]
(Effect of the fourth embodiment)
According to this embodiment, when only a print area is displayed and a specific part of the print area is specified with a mouse or a pen and dragged while holding it, the print area frame is reduced as necessary. The printing area can be moved to a desired size / position.
For example, when it is desired to bring the person to the right end by trimming an image in which the person is reflected in the center, conventionally, it has been necessary to reduce the print area and then move it. By simply dragging the upper right division point area to the position of the person, the print area frame is reduced as necessary, so that an image with a preferable composition can be obtained with a single operation.
[0083]
(Fifth embodiment)
In the above embodiment, the selected trimming frame is only reduced, but in this embodiment, the size of the trimming frame at the start of trimming is stored, and the trimming area frame is enlarged / reduced by the operation at the time of trimming. The operation will be described with reference to the flowchart of FIG.
[0084]
In step S1301, the trimming area frame is stored.
[0085]
In step S1302, the position (x0, y0) of the mouse in the image coordinate system is acquired.
[0086]
In step S1303, a predetermined waiting time is set in order to capture the movement of the mouse.
[0087]
In step S1304, the position (x1, y1) of the mouse after movement in the image coordinate system is acquired.
[0088]
In step S1305, new trimming area coordinates (x ′, y ′), width (w ′), and height (h ′) are obtained. That is, the position and enlargement ratio (including reduction) of the new trimming area are calculated. A method of calculating x, 'y', w ', h' will be described later.
[0089]
In step S1306, a new trimming area specified by x, 'y', w ', h' obtained in step S1305 is drawn.
[0090]
In step S1307, it is determined whether or not the drag of the mouse has ended. If it has ended, the process ends. If it has not ended, the process returns to step S1302.
[0091]
A method for obtaining the position, width, and height of a new trimming frame will be described with reference to FIG.
[0092]
Here, for the sake of simplicity, a method for obtaining coordinates when the dividing point area is dragged from the right to the left with the x ′ coordinate and the width w ′ being one-dimensional coordinates will be described.
[0093]
First, reference numeral 1401 represents an image at the time of trimming and a trimming area frame. The width of the trimming frame is w. (Length from the division point to the left end of the trimming frame): (Length from the division point to the right end of the trimming frame) = α: (1-α).
[0094]
Next, reference numeral 1402 indicates that the moving region protrudes outside the image during trimming. Let x be the coordinates at this time.
[0095]
Next, in 1403, the trimming frame is finally reduced so that it fits in the image. If the coordinates and width at this time are x ′ and w ′, the following equation is established.
x + wα = x '+ w'α
[0096]
Here, since x ′ = 0, w ′ = (1 / α) x + w holds, and the position and size of the trimming frame can be acquired by extending this to two dimensions.
[0097]
As described above, by remembering the first trimming frame, it is possible to simultaneously enlarge and reduce the trimming frame simply by moving the trimming frame.
[0098]
Here, although there are four division point areas in this embodiment, the number of division point areas can be arbitrarily increased.
[0099]
In the present embodiment, for example, the position of the dividing point is the three dividing point of the trimming frame. The three division points are division points that satisfy the condition of (length between one end of the trimming frame and the division point) :( length between the other end of the trimming frame and the division point) = 2: 1.
[0100]
Further, the position of the dividing point area is not limited to three dividing points, and may be arranged at an important position in the composition of other images such as a golden dividing point of a trimming frame. The golden dividing point is (the length between one end of the trimming frame and the dividing point) :( the length between the other end of the trimming frame and the dividing point) = ((√5) −1): 2. This is a dividing point that satisfies.
[0101]
In the fourth embodiment, the position and enlargement ratio of the trimming area are calculated and drawn based on the moving state, but in the fifth embodiment, the trimming area frame before the movement is stored and moved in step S1301. Draw by calculating the magnification based on the previous state.
[0102]
(Effect of 5th Embodiment)
According to this embodiment, while displaying only the print area, when a specific part of the print area is specified with a mouse or a pen and dragged while grabbing it, the print area frame is enlarged or reduced as necessary. The print area is reduced and can be moved to a desired size / position.
For example, when it is desired to bring the person to the right end by trimming an image in which the person is reflected in the center, conventionally, it has been necessary to reduce the print area and then move it. By simply dragging the upper right division point area to the position of the person, the print area frame is reduced as necessary, so that an image with a preferable composition can be obtained with a single operation.
Further, since the trimming frame at the start of the drag is stored, the rectangle at the start of the drag can be returned during the drag operation.
[0103]
