Abstract

This application provides an image acquisition method and apparatus, where the method includes: receiving an input gesture performed on an image captured by a camera; determining a filter parameter according to a current filter type and the gesture; performing a filter operation corresponding to the filter type on the image according to the filter parameter; and displaying, in real time, the image processed through the filter operation.

Claims

1. An image acquisition method, the method comprising the following steps:

receiving an input gesture performed on an image captured by a camera;

determining a filter parameter according to a current filter type and the gesture;

performing a filter operation corresponding to the filter type on the image according to the filter parameter; and

displaying the image processed through the filter operation in real time.

2. The method according to claim 1, wherein the filter parameter comprises at least one of an operation instruction, filter strength, a filter color, a filter size, and filter transparency.

3. The method according to claim 2, wherein the operation instruction is acquired according to a type of the gesture;

and the at least one of the filter strength, the filter color, the filter size, and the filter transparency is acquired according to a scale value of the gesture.

4. The method according to claim 1, before the receiving an input gesture, further comprising:

receiving input selection information; and

determining the current filter type according to the selection information.

5. The method according to claim 1, wherein the filter parameter comprises filter coordinates information.

6. The method according to claim 5, wherein the filter coordinates information is acquired according to a position of the gesture on the image.

7. The method according to claim 2, wherein the operation instruction comprises at least one of a swipe instruction, a stretch instruction, a rotate instruction, a tap instruction, and a double-tap instruction.

8. The method according to claim 1, wherein the image captured by the camera comprises a video or a picture.

9. An image acquisition apparatus, the apparatus comprising:

a receiving unit, configured to receive an input gesture performed on an image captured by a camera;

an acquisition unit, configured to determine a filter parameter according to a current filter type and the gesture;

a performing unit, configured to perform a filter operation corresponding to the filter type on the image according to the filter parameter; and

an output unit, configured to display the image processed through the filter operation in real time.

10. The apparatus according to claim 9, wherein the filter parameter comprises at least one of an operation instruction, filter strength, a filter color, a filter size, and filter transparency.

11. The apparatus according to claim 10, wherein the operation instruction is acquired according to a type of the gesture;

and the at least one of the filter strength, the filter color, the filter size, and the filter transparency is acquired according to a scale value of the gesture.

12. The apparatus according to claim 9, wherein the apparatus further comprises:

a filter selection unit, configured to receive input selection information, and determining the current filter type according to the selection information.

13. The apparatus according to claim 9, wherein the filter parameter comprises filter coordinates information.

14. The apparatus according to claim 9, wherein the filter coordinates information is acquired according to a position of the gesture on the image.

15. The apparatus according to claim 10, wherein the operation instruction comprises at least one of a swipe instruction, a stretch instruction, a rotate instruction, a tap instruction, and a double-tap instruction.

16. The apparatus according to claim 9, wherein the image captured by the camera comprises a video or a picture.
