Abstract

A screen frame cropping method, a screen frame cropping apparatus, and a computer program product adapted to an electronic apparatus having a touch screen are provided. In the screen frame cropping method, a frame is displayed on the touch screen, and a first touch and a second touch preformed by a user on the touch screen are detected. When the first touch and the second touch satisfy a predetermined condition, a cropped frame of the frame is stored as an image file. The cropped frame is determined according to at least one first touch position of the first touch and at least one second touch position of the second touch.

Claims

1. A screen frame cropping method, adapted to an electronic apparatus having a touch screen, the method comprising:

displaying a frame on the touch screen;

detecting a first touch and a second touch performed by a user on the touch screen; and

when the first touch and the second touch satisfy a predetermined condition, storing a cropped frame of the frame as an image file;

wherein the cropped frame is determined according to at least one first touch position of the first touch and at least one second touch position of the second touch.

2. The screen frame cropping method according to claim 1, wherein the predetermined condition comprises:

one of a first displacement of the first touch and a second displacement of the second touch being greater than a predetermined value.

3. The screen frame cropping method according to claim 2, wherein the predetermined condition comprises:

one of the first touch and the second touch starting from a predetermined starting border area of the touch screen.

4. The screen frame cropping method according to claim 3, wherein the cropped frame is determined according to a first starting touch position of the first touch, a second starting touch position of the second touch, and a first current touch position of the first touch and a second current touch position of the second touch when one of a first displacement of the first touch and a second displacement of the second touch is greater than a predetermined value.

5. The screen frame cropping method according to claim 1, wherein the cropped frame is a rectangle comprising a cropping area and a transparent area outside the cropping area, wherein the cropping area and the transparent area are determined according to a first moving path of the first touch and a second moving path of the second touch.

6. The screen frame cropping method according to claim 1 further comprising:

recognizing the cropped frame by using a character recognition technique to generate at least one character; and

storing the at least one character as a text file.

7. The screen frame cropping method according to claim 1, wherein the predetermined condition comprises:

one of the first touch and the second touch ending at a predetermined ending border area of the touch screen.

8. The screen frame cropping method according to claim 1, wherein the predetermined condition comprises:

one of a first touch time of the first touch and a second touch time of the second touch being greater than a predetermined value.

9. The screen frame cropping method according to claim 1, wherein the cropped frame is determined according to a first starting touch position of the first touch, a second starting touch position of the second touch, a first ending touch position of the first touch, and a second ending touch position of the second touch.

10. A screen frame cropping apparatus, comprising:

a touch screen;

a storage unit, recording a plurality of modules; and

one or a plurality of processing units, coupled to the touch screen and the storage unit, and accessing and executing the modules recorded in the storage unit, wherein the modules comprise;

a display module, displaying a frame on the touch screen;

a detection module, detecting a first touch and a second touch performed by a user on the touch screen; and

a cropping module, storing a cropped frame of the frame as an image file when the first touch and the second touch satisfy a predetermined condition;

wherein the cropped frame is determined according to at least one first touch position of the first touch and at least one second touch position of the second touch.

11. The screen frame cropping apparatus according to claim 10, wherein the predetermined condition comprises one of a first displacement of the first touch and a second displacement of the second touch being greater than a predetermined value.

12. The screen frame cropping apparatus according to claim 11, wherein the predetermined condition comprises one of the first touch and the second touch starting from a predetermined starting border area of the touch screen.

13. The screen frame cropping apparatus according to claim 10, wherein the cropped frame is determined according to a first starting touch position of the first touch, a second starting touch position of the second touch, and a first current touch position of the first touch and a second current touch position of the second touch when one of a first displacement of the first touch and a second displacement of the second touch is greater than a predetermined value.

14. The screen frame cropping apparatus according to claim 10, wherein the cropped frame is a rectangle comprising a cropping area and a transparent area outside the cropping area, wherein the cropping area and the transparent area are determined according to a first moving path of the first touch and a second moving path of the second touch.

15. The screen frame cropping apparatus according to claim 10, wherein the modules further comprise:

a character recognition module, recognizing the cropped frame by using a character recognition technique to generate at least one character, and storing the at least one character as a text file.

16. The screen frame cropping apparatus according to claim 10, wherein the predetermined condition comprises one of the first touch and the second touch ending at a predetermined ending border area of the touch screen.

17. The screen frame cropping apparatus according to claim 10, wherein the predetermined condition comprises one of a first touch time of the first touch and a second touch time of the second touch being greater than a predetermined value.

18. The screen frame cropping apparatus according to claim 10, wherein the cropped frame is determined according to a first starting touch position of the first touch, a second starting touch position of the second touch, a first ending touch position of the first touch, and a second ending touch position of the second touch.

19. A computer program product, loaded into an electronic apparatus to execute following steps:

displaying a frame on a touch screen of the electronic apparatus;

detecting a first touch and a second touch performed by a user on the touch screen; and

when the first touch and the second touch satisfy a predetermined condition, storing a cropped frame of the frame as an image file;

wherein the cropped frame is determined according to at least one first touch position of the first touch and at least one second touch position of the second touch.
