Abstract

A screen capture method, an apparatus, and a terminal device where a part of an image in a screen display region can be captured by means of gesture recognition. When it is detected that two fingers swipe parallel in a same direction on a screen, acquiring a screen capture region according to the same-direction parallel swiping; and acquiring, according to the screen capture region, an image displayed in the screen capture region. According to the screen capture method, a screen capture operation is performed by recognizing same-direction parallel swiping of two fingers on a screen, so that a user can capture an image displayed in a part of a region of the screen according to an individual requirement, and the screen capture method is applicable to various touch-operation terminal devices without the help of an external tool, thereby simplifying the operation and improving user experience.

First claim

What is claimed is:

1. A screen capture method, comprising:
detecting, according to a same-direction parallel swiping operation of two fingers, whether start point positions and end point positions of the same-direction parallel swiping operation are outside a screen edge;
detecting that the same-direction parallel swiping operation is an invalid screen capture operation when the start point positions and the end point positions of the same-direction parallel swiping operation are outside the screen edge;
acquiring a screen capture region according to the same-direction parallel swiping operation when detecting that the two fingers swipe parallel in the same direction on a screen and after detecting that the start point positions and the end point positions are within the screen edge, wherein the screen capture region is determined by the start point positions, the end point positions, and swipe tracks of the same-direction parallel swiping operation; and
acquiring, according to the screen capture region, an image displayed in the screen capture region.

2. The screen capture method according to claim 1 , wherein acquiring the screen capture region comprises:
acquiring the swipe tracks of the same-direction parallel swiping operation according to a same-direction parallel swiping motion of the two fingers; and
acquiring the start point positions or end point positions of the same-direction parallel swiping operation or acquiring the start point positions and the end point position of the same-direction parallel swiping operation according to the same-direction parallel swiping operation of the two fingers.

3. The screen capture method according to claim 2 , wherein acquiring the screen capture region comprises acquiring the screen capture region according to at least one of the start point positions, the end point positions, or the acquired swipe tracks when the start point positions or the end point positions are at the screen edge or when the start point positions and the end point positions are at the screen edge.

4. The screen capture method according to claim 3 , wherein acquiring the screen capture region according to at least one of the start point positions, the end point positions, or the acquired swipe tracks comprises acquiring the screen capture region according to a region enclosed by the acquired swipe tracks and one of horizontal lines or vertical lines when the start point positions are at the screen edge.

5. The screen capture method according to claim 3 , wherein acquiring the screen capture region according to at least one of the start point positions, the end point positions, or the acquired swipe tracks comprises:
acquiring the screen capture region according to a region enclosed by connection lines between the start point positions and the end point positions and horizontal lines or by the connection lines and vertical lines when the start point positions or the end point positions are at the screen edge or when the start point positions and the end point positions are at the screen edge; or
acquiring the screen capture region according to a region enclosed by successively connecting the start point positions and the end point positions when the start point positions or the end point positions are at the screen edge or when the start point positions and the end point positions are at the screen edge.

6. The screen capture method according to 23 , wherein the region enclosed is non-rectangular, and wherein the acquired screen capture region is a largest rectangular area covered by an area of the region enclosed or a smallest rectangular area that covers the area of the region enclosed.

7. A screen capture apparatus, comprising:
a memory comprising instructions; and
a computer processor coupled to the memory, wherein the instructions cause the computer processor to be configured to:
detect, according to a same-direction parallel swiping operation of two fingers, whether start point positions and end point positions of the same-direction parallel swiping operation are outside a screen edge;
detect that the same-direction parallel swiping operation is an invalid screen capture operation when the start point positions and the end point positions of the same-direction parallel swiping operation are outside the screen edge;
acquire a screen capture region according to the same-direction parallel swiping operation when detecting that the two fingers swipe parallel in the same direction on a screen and after detecting that the start point positions and the end point positions are within the screen edge, wherein the screen capture region is determined by the start point positions, the end point positions, and swipe tracks of the same-direction parallel swiping operation; and
acquire, according to the screen capture region, an image displayed in the screen capture region.

8. The screen capture apparatus according to claim 7 , wherein after detecting the same direction parallel swiping operation of the two fingers on the screen, the instructions further cause the computer processor to be configured to:
acquire swipe tracks of the same-direction parallel swiping operation according to a same-direction parallel swiping motion of the two fingers; and
acquire the start point positions or the end point positions of the same-direction parallel swiping operation or acquire the start point positions and the end point positions of the parallel swiping operation according to the parallel swiping-motion of the two fingers.

9. The screen capture apparatus according to claim 8 , wherein the instructions further cause the computer processor to be configured to acquire the screen capture region according to at least one of the start point positions, the end point positions, or the acquired swipe tracks when the start point positions or the end point positions are in a display region at the screen edge or when the start point positions and the end point positions are in a display region at the screen edge.

10. The screen capture apparatus according to claim 9 , wherein the instructions further cause the computer processor to be configured to acquire the screen capture region according to a region enclosed by the acquired swipe tracks and horizontal lines or by the acquired swipe tracks and vertical lines when the start point positions or the end point positions are in the display region at the screen edge or when the start point positions and the end point positions are in the display region at the screen edge.

11. The screen capture apparatus according to claim 9 , wherein the instructions further cause the computer processor to be configured to:
acquire the screen capture region according to a region enclosed by connection lines between the start point positions and the end point positions and horizontal lines or by the connection lines and vertical lines when at least one of the start point positions or the end point positions are in the display region at the screen edge; and
acquire the screen capture region according to a region enclosed by successively connecting the start point positions and the end point positions when the start point positions or the end point positions are in the display region at the screen edge or when the start point position and the end point positions are in the display region at the screen edge.

12. The screen capture apparatus according to claim 11 , wherein the screen capture region is a largest rectangular area covered by an area of the enclosed region or a smallest rectangular area that covers the area of the enclosed region when the region is non-rectangular.

13. A terminal device, comprising:
a memory comprising in
