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:

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

determining a filter operation from a plurality of filter operations corresponding to a current filter type, where the determination is according to a pre-stored relation which associates the filter operation with the filter type and the type of the gesture;

determining a filter parameter of the filter operation according to the current filter type and a scale value of the gesture;

performing the filter operation 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 filter strength, a filter color, a filter size, and filter transparency.

3. 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.

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

5. The method according to claim 4, wherein the filter coordinates information is acquired according to a position of the gesture on the image.

6. The method according to claim 1, wherein the filter parameter comprises an operation instruction, 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.

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

8. An image acquisition apparatus, the apparatus comprising a processor and a memory, the memory stores computer-readable instructions executable by the processor to:

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

determine a filter operation from a plurality of filter operations corresponding to a current filter type, where the determination is according to a pre-stored relation which associates the filter operation with the filter type and the type of the gesture;

determine a filter parameter of the filter operation according to the current filter type and a scale value of the gesture;

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

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

9. The apparatus according to claim 8, wherein the filter parameter comprises at least one of filter strength, a filter color, a filter size, and filter transparency.

10. The apparatus according to claim 8, wherein the computer-readable instructions are executable by the processor to:

receive input selection information, and determine the current filter type according to the selection information.

11. The apparatus according to claim 8, wherein the filter parameter comprises filter coordinates information.

12. The apparatus according to claim 11, wherein the filter coordinates information is acquired according to a position of the gesture on the image.

13. The apparatus according to claim 8, wherein the filter parameter comprises an operation instruction, 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.

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