Abstract

A method for controlling a printing apparatus includes displaying a display image on a display unit based on image data, detecting a plurality of positions touched on a touch panel, for each of the positions detected on the touch panel, designating a position on the display image displayed on the display unit according to the position detected on the touch panel, obtaining an aspect ratio of a printing area, determining a crop area of the display image having the aspect ratio of the printing area and including all of the designated positions on the display image, and printing an image on a recording sheet based on the determined crop area.

Claims

1. A method for controlling a printing apparatus for printing an image on a recording sheet and including a display unit configured to display an image and a touch panel provided in a front face of the display unit, the method comprising:

displaying a display image on the display unit based on image data;

detecting a plurality of positions touched on the touch panel;

for each of the positions detected on the touch panel, designating a position on the display image displayed on the display unit according to the position detected on the touch panel;

obtaining an aspect ratio of a printing area;

determining a crop area of the display image having the aspect ratio of the printing area and including all of the designated positions on the display image; and

printing an image on a recording sheet based on the determined crop area.

2. The method according to claim 1, wherein the aspect ratio of the printing area is obtained based on a print setting.

3. The method according to claim 1, further comprising reading image data from a memory card and wherein the image displayed on the display unit is based on the image data read from the memory card.

4. The method according to claim 1, wherein the image data includes a thumbnail image and the thumbnail image is displayed on the display unit.

5. The method according to claim 1, further comprising:

receiving a rotate instruction;

determining whether the image can be rotated based on the determined crop area;

displaying a rotated image if it is determined that the display image can be rotated based on the determined crop area; and

displaying an indication that the display image can not be rotated if it is determined that the image can not be rotated based on the crop area.

6. A computer-readable recording medium in which a computer-executable program adapted to execute the method according to claim 1 is recorded.

7. A printing apparatus configured to print an image on a recording sheet, comprising:

a display unit configured to display the image;

a touch panel provided on a front face of the display unit;

a display control unit configured to display a display image on the display unit based on the image data;

a detection unit configured to detect a position touched on the touch panel;

a determination unit configured to determine an area on the display image based on a plurality of positions on the displayed image which are designated according to a plurality of respective positions detected by the detection unit, and an aspect ratio of a printing area; and

a print unit configured to print the image on the recording sheet based on image data corresponding to the area determined by the determination unit taken out from the image data.

8. A method for selecting an image from an area, comprising:

displaying a display image on a display device based on image data;

designating a position on the displayed display image according to an instruction from a user; and

determining an area on the display image based on the designated position on the display image, wherein the determined area includes a plurality of positions on the designated display image and has a predetermined aspect ratio.

9. The method according to claim 8, further comprising printing an image on a recording sheet based on image data corresponding to the determined area taken out from the image data, wherein the predetermined aspect ratio is an aspect ratio of a printing area of the image to be printed.

10. The method according to claim 8, further comprising enlarging the image in the determined area taken out from the image data and displaying the enlarged image on the display device, wherein the predetermined aspect ratio is an aspect ratio of the displayed image.

11. The method according to claim 8, further comprising determining an area in the display image, wherein an average of the plurality of positions designated on the display image is at a center of the area on the display image.

12. A computer-readable recording medium in which a computer-executable program adapted to execute the method according to claim 8 is recorded.
