Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 6:
7. A method performed by an electronic device, the method comprising:
receiving a first image from a camera of the electronic device;
generating a second image by lowering a resolution of the first image from N*M to (N/n)*(M/m);
putting the second image into an artificial intelligence (AI) model learned using a first training image having a resolution of (N/n)*(M/m) and a second training image having a resolution of (N/n)*(M/m) and making a pair with the first training image as an input value;
obtaining a third image from a resultant value output from the AI model, the third image representing a difference between the second image and an image corresponding to the second image in which artifacts are not present;
generating a fourth image by increasing a resolution of the third image from (N/n)*(M/m) to N*M; and
generating a fifth image by subtracting the fourth image from the first image.
