Image acquisition method and apparatus
View Patent ↗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.
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.
