Abstract

To provide an image editing technique that enables a user to perform movement and magnification of an image with a single operation, and to perform trimming while grasping image composition in printing, the image editing method includes a step of instructing to move an arbitrary point of an image displayed in an image display area among image data; a step of calculating an image movement amount and a magnification ratio in response to the instruction to move the arbitrary point; and a step displaying a predetermined area of the image data in the image display area on the basis of the image movement amount and the magnification ratio, which are calculated in the calculating step.

Claims

1. An image editing method comprising the steps of:

instructing to move an arbitrary point of an image displayed in an image display area among image data;

calculating an image movement amount and a magnification ratio in response to the instruction to move the arbitrary point; and

displaying a predetermined area of the image data in the image display area on the basis of image movement amount and the magnification ratio, which are calculated in the calculating step.

2. An image editing method according to claim 1,

wherein the image display area is an image print area indicating an image area to be printed.

3. An image editing method according to claim 2, further comprising:

a step of instructing to print the image displayed in the image display area.

4. An image editing method according to claim 1,

wherein when it is instructed to move the arbitrary point so that an end of the image data in a direction opposite to a moving direction is exceeded, the image is magnified based on an exceeding amount and the magnified image is displayed.

5. An image editing method according to claim 1,

wherein the predetermined area of the image data is displayed in the displaying step so that the arbitrary point, whose movement is instructed in the instructing step, is moved to a post-movement point regardless of the magnification ratio.

6. An image editing method according to claim 1,

wherein the calculating step calculates the image movement amount and the magnification ratio so that the arbitrary point, whose movement is instructed in the instructing step, is moved to the post-movement point without generating any margin in the image display area.

7. An image editing method according to claim 1,

wherein while it is instructed in the instructing step to move the arbitrary point, the displaying step displays the predetermined area of the image data in the image display area based on the image movement amount and the magnification ratio, which are calculated in the calculating step.

8. An image editing method according to claim 1,

wherein while it is instructed in the instructing step to move the arbitrary point, the displaying step displays the predetermined area of the image data in the image display area based on the image movement amount, which is calculated in the calculation step, without changing image size, and

when it is ended that the instructing step instructs the movement of the arbitrary point, the displaying step displays the predetermined area of the image data in the image display area based on the image movement amount and the magnification ratio, which are calculated in the calculating step.

9. An image editing method according to claim 1,

wherein the calculating step calculates the magnification ratio based on a post-movement point designated during the instruction in the instructing step.

10. An image editing method according to claim 1,

wherein the calculating step calculates the magnification ratio based on a post-movement point designated at a start of the instruction in the instructing step.

11. An image editing apparatus comprising:

means for instructing to move an arbitrary point of an image displayed in an image display area among image data;

means for calculating an image movement amount and a magnification ratio in response to the instruction to move the arbitrary point; and

means for displaying a predetermined area of the image data in the image display area on the basis of the image movement amount and the magnification ratio, which are calculated by the calculating means.

12. A program for causing a computer to execute an image editing method, comprising:

instructing to move an arbitrary point of an image displayed in an image display area among image data;

calculating an image movement amount and a magnification ratio in response to the instruction to move the arbitrary point; and

displaying a predetermined area of the image data in the image display area on the basis of the image movement amount and the magnification ratio, which are calculated in the calculating step.

13. A computer-readable recording medium on which a program for causing a computer to execute an image editing method is recorded, the method comprising:

instructing to move an arbitrary point of an image displayed in an image display area among image data;

calculating an image movement amount and a magnification ratio in response to the instruction to move the arbitrary point; and

displaying a predetermined area of the image data in the image display area on the basis of the image movement amount and the magnification ratio, which are calculated in the calculating step.

14. An image editing method comprising the steps of:

performing a trimming process on image data in a trimming mode; and

displaying a grid on an image to be subjected to the trimming process when the trimming mode is set.

15. An image editing method according to claim 14,

wherein the trimming step performs the trimming process in accordance with a trimming operation, and

while it is detected that the trimming operation is performed, the grid displaying step displays the grid on the image.

16. An image editing method according to claim 14,

wherein grid displaying step displays the grid which suggests appropriate framing of a main object in the image.

17. An image editing method according to claim 16,

wherein the grid displaying step displays the grid which divides the image based on a golden section.

18. An image editing method according to claim 17,

wherein the grid displaying step displays the grid which vertically and horizontally divides the image into equal parts.

19. An image editing method according to claim 18,

wherein the grid displaying step displays the grid which vertically and horizontally divides the image into at least one of three, four, and five equal parts.

20. An image editing method according to claim 17,

wherein the grid displaying step displays the grid which is obtained by drawing a diagonal line in a rectangular image and drawing perpendicular lines from remaining vertexes of the image to the diagonal line.

21. An image editing method according to claim 14,

wherein the grid displaying step is arranged to switch between displaying and non-displaying of the grid.

22. An image editing method according to claim 14,

wherein the trimming step performs the trimming process by changing at least one of a size and a position of the image.

23. An image editing method according to claim 14,

wherein the trimming step is arranged to change at least one of a size and a position of a trimming frame which is displayed on the image to indicate a trimming image area in accordance with a trimming instruction, and display the trimming frame changed in at least one of the size and the position, and

the grid displaying step displays the grid in the trimming frame changed in at least one of the size and the position.

24. An image editing method according to claim 14,
