Abstract

A mobile terminal and a photograph deletion method thereof are disclosed. The method comprises: pre-storing in the mobile terminal a preset touch gesture used for deleting a picture from a photography interface during photography, and mapping the preset touch gesture to a deletion command; receiving a user'"'"'s touchscreen command to determine whether the users touch gesture matches the preset touch gesture when the photography interface of the mobile terminal requires deletion of a picture; if yes, determining a deletion target according to action points of the touch gesture; and moving deletion target into a recycling bin. The captured picture is rapidly deleted from the photography interface through a simple touchscreen gesture without exiting the camera application program and with no need to manually switch an operation interface.

Claims

1-19. -19. (canceled)

20. A mobile terminal-based photograph deletion method, comprising steps of:

pre-storing a preset touch gesture in a mobile terminal and mapping the preset touch gesture to a deletion command;

receiving a touch gesture on a photography interface of a touchscreen and determining whether the touch gesture indicates a click command when the mobile terminal is used to take a photograph;

determining whether the touch gesture matches the preset touch gesture when the touch gesture is determined not to indicate the click command;

determining a target according to action points of the touch gesture when the touch gesture matches the preset touch gesture; and

moving the target to a recycle bin.

21. The mobile terminal-based photograph deletion method according to claim 20, wherein the target comprises a picture or a short film.

22. The mobile terminal-based photograph deletion method according to claim 20, further comprising a step of receiving a target retrieving command by the mobile terminal for recovering the target from the recycle bin to a location where the target was before the target was moved to the recycle bin or a specified location after the step of moving the target to the recycle bin.

23. The mobile terminal-based photograph deletion method according to claim 20, wherein the preset touch gesture is an X-shaped gesture on the touchscreen of the mobile terminal.

24. The mobile terminal-based photograph deletion method according to claim 23, wherein the step of determining whether the touch gesture matches the preset touch gesture comprises:

determining whether the touch gesture satisfies all of the following conditions;

A. two lines drawn by the touch gesture are approximate to straight lines;

B. the two lines drawn by the touch gesture have only one intersection point and the intersection point is at a middle part of three equal parts of the two lines; and

C. an angle between the two lines ranges from 45 to 135 degrees;

determining that the touch gesture matches the X-shaped gesture when all three of the conditions A, B, and C are satisfied, and determining that the touch gesture does not match the X-shaped gesture when any one of the three conditions A, B, and C is not satisfied.

25. The mobile terminal-based photograph deletion method according to claim 20, wherein the recycle bin caches a preset number of targets in chronological order.

26. The mobile terminal-based photograph deletion method according to claim 25, wherein the step of moving the target to the recycle bin comprises:

when the number of the cached targets in the recycle bin has reached the preset number, deleting a foremost cached target from the recycle bin and then moving the target to the recycle bin.

27. A mobile terminal-based photograph deletion method, comprising steps of:

pre-storing a preset touch gesture in a mobile terminal and mapping the preset touch gesture to a deletion command;

receiving a touch gesture on a photography interface of a touchscreen and determining whether the touch gesture matches the preset touch gesture when the mobile terminal is used to take a photograph;

determining a target according to action points of the touch gesture when the touch gesture matches the preset touch gesture; and

moving the target to a recycle bin.

28. The mobile terminal-based photograph deletion method according to claim 27, wherein the target comprises a picture or a short film.

29. The mobile terminal-based photograph deletion method according to claim 27, further comprising a step of receiving a target retrieving command by the mobile terminal for recovering the target from the recycle bin to a location where the target was before the target was moved to the recycle bin or a specified location after the step of moving the target to the recycle bin.

30. The mobile terminal-based photograph deletion method according to claim 27, wherein the preset touch gesture is an X-shaped gesture on the touchscreen of the mobile terminal.

31. The mobile terminal-based photograph deletion method according to claim 30, wherein the step of determining whether the touch gesture matches the preset touch gesture comprises:

determining whether the touch gesture satisfies all of the following conditions;

A. two lines drawn by the touch gesture are approximate to straight lines;

B. the two lines drawn by the touch gesture have only one intersection point and the intersection point is at a middle part of three equal parts of the two lines; and

C. an angle between the two lines ranges from 45 to 135 degrees;

determining that the touch gesture matches the X-shaped gesture when all three of the conditions A, B, and C are satisfied, and determining that the touch gesture does not matches the X-shaped gesture when any one of the three conditions A, B, and C is not satisfied.

32. The mobile terminal-based photograph deletion method according to claim 27, wherein the recycle bin caches a preset number of targets in chronological order.

33. The mobile terminal-based photograph deletion method according to claim 32, wherein the step of moving the target to the recycle bin comprises:

when the number of the cached targets in the recycle bin has reached the preset number, deleting a foremost cached target from the recycle bin and then moving the target to the recycle bin.

34. A mobile terminal, comprising:

an arrangement module for pre-storing a preset touch gesture in the mobile terminal and establishing a correspondence between the preset touch gesture and a deletion command;

a gesture determining module for receiving a touch gesture on a photography interface of a touchscreen and determining whether the touch gesture matches the preset touch gesture when the mobile terminal is used to take a photograph;

if yes, outputting a target determination signal;

a target determining module for receiving the target determination signal and determining a target according to action points of the touch gesture; and

a deletion control module for moving the target determined by the target determining module to a recycle bin when the gesture determining module determines that the touch gesture matches the preset touch gesture.

35. The mobile terminal according to claim 34, wherein the target comprises a picture or a short film.

36. The mobile terminal according to claim 34, further comprising:

a target recovering module for receiving a target retrieving command and recovering the target from the recycle bin to a location where the target was before the target was moved to the recycle bin or a specified location; and

the arrangement module further for presetting the recycle bin used to cache a preset number of targets in chronological order.

37. The mobile terminal according to claim 34, wherein the preset touch gesture is an X-shaped gesture, and wherein the gesture determining module further comprises:

a first determination unit for determining whether lines drawn by the touch gesture are two lines approximate to straight lines;

if yes, notifying a second determination unit to work;

if no, determining that the touch gesture does not match the X-shaped gesture;

the second determination unit for determining whether the two lines drawn by the touch gesture have only one intersection point and the intersection point is at a middle part of three equal parts of the two lines;

if yes, notifying a third determination unit to work;

if no, determining that the touch gesture does not match the X-shaped gesture;

the third determination unit for determining whether an angle between the two lines ranges from 45 to 135 degrees;
