Abstract

According to an embodiment of the present disclosure, an electronic device comprises: a camera; a display; a memory; and at least one processor electrically connected to the display and the memory. The processor obtains an input of selecting a first image, generates a color filter by comparing the first image and a second image having a color pattern different from the first image, obtains a third image, and generates a fourth image by applying the generate color filter to the third image. The processor derives a function by comparing color values of pixels of the first image and the second image, and coefficients of the function. The color filter may include the function derived by comparing the first image and the second image, the coefficients of the function, and a color lookup table generated on the basis of the derived function. The processor stores the generated color filter in the memory and generates the fourth image by applying the stored color filter to the third image.

First claim

What is claimed is:

1. An electronic device comprising:
a camera;
a display;
memory storing instructions; and
at least one processor,
wherein the instructions, when executed by the at least one processor, cause the electronic device to:
control the display to display a first icon for adding a color filter to a filter list of the electronic device and a target image,
acquire a first user input for selecting the first icon,
based on acquiring the first user input, control the display to display an image list corresponding to a plurality of images stored in the memory, wherein the plurality of images included in the image list are used to generate a color filter to be added to the filter list,
acquire a second user input for selecting a first image from the plurality of images,
based on acquiring the second user input, generate a color filter based on the first image, and
control the display to display a second icon representing the generated color filter and a fixed image in which
the generated color filter is applied to the target image.

2. The electronic device of claim 1 , wherein the target image includes at least one image acquired through the camera of the electronic device or an image stored in the memory.

3. The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor, cause the electronic device to store the generated color filter in the memory of the electronic device.

4. The electronic device of claim 1 , wherein the plurality of images includes at least one image acquired through the camera of the electronic device and at least one image acquired from a server.

5. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:
control the display to display a third icon for a name of the generated color filter;
acquire a third user input for selecting the third icon;
based on acquiring the third user input, control the display to display a visual object for obtaining the name of the generated color filter;
obtain the name of the color filter based on a fourth user input for the visual object; and
control the display to display the obtained name of the color filter in association with the second icon.

6. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:
generate a second image with a color pattern different from a color pattern of the first image; and
generate the color filter using the first image and the second image.

7. The electronic device of claim 6 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:
generate the second image based on a characteristic of at least one object in the first image.

8. The electronic device of claim 6 , wherein the color filter includes at least one of a function derived by comparing color values of pixels of the first image and the second image, coefficients of the function, or a color lookup table.

9. The electronic device of claim 6 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:
match the first image to the second image;
compare color values of overlapping pixels based on the matching; and
generate the color filter based on the comparison.

10. The electronic device of claim 6 , wherein the second image corresponds to an original image of the first image, and
wherein the instructions, when executed by the at least one processor, cause the electronic device to generate the second image using at least one of machine learning, big data technology, or artificial intelligence.

11. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to provide a GUI (graphical user interface) for controlling intensity of a filter effect of the generated color filter.

12. A method of controlling an electronic device, the method comprising:
displaying, on a display of the electronic device, a first icon for adding a color filter to a filter list of the electronic device and a target image,
acquiring a first user input for selecting the first icon,
based on acquiring the first user input, displaying an image list corresponding to a plurality of images stored in a memory of the electronic device, wherein the plurality of images included in the image list are used to generate a color filter to be added to the filter list,
acquiring a second user input for selecting a first image from the plurality of images;
based on acquiring the second user input, generating a color filter based on the first image; and
displaying a second icon representing the generated color filter and a fixed image in which the generated color filter is applied to the target image.

13. The method of claim 12 , wherein the target image includes at least one image acquired through a camera of the electronic device or an image stored in the memory.

14. The method of claim 12 , comprising:
displaying a third icon for a name of the generated color filter;
acquiring a third user input for selecting the third icon;
based on acquiring the third user input, displaying a visual object for obtaining the name of the generated color filter;
obtaining the name of the color filter based on a fourth user input for the visual object; and
displaying the obtained name of the color filter in association with the second icon.

15. The method of claim 12 , comprising:
generating a second image with a color pattern different from a color pattern of the first image; and
generating the color filter using the first image and the second image.

16. One or more non-transitory computer-readable storage media storing one or more programs configured to be executed by one or more processors of an electronic device, the one or more programs including instructions for:
displaying, on a display of the electronic device, a first icon for adding a color filter to a filter list of the electronic device and a target image;
acquiring a first user input for selecting the first icon;
based on acquiring the first user input, displaying an image list corresponding to a plurality of images stored in a memory of the electronic device, wherein the plurality of images included in the image list are used to generate a color filter to be added to the filter list;
acquiring a second user input for selecting a first image from the plurality of images;
based on acquiring the second user input, generating a color filter based on the first image; and
displaying a second icon representing the generated color filter and a fixed image in which the generated color filter is applied to the target image.
