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

Claim 14:
15. An electronic device, comprising:
a display;
interface circuitry; and
a processor configured to control the electronic device to:
process a signal received from an external display apparatus through the interface circuitry, the signal to correspond to an image displayed on the external display apparatus;
control the display to display a mirrored image based on the processed signal, the mirrored image comprising a plurality of frames;
identify a size of an area in which a pixel change between two consecutive frames among the plurality of frames is greater than or equal to a first threshold;
based on a ratio of the identified size of the area to a size of a frame of the consecutive frames being greater than or equal to a second threshold, detect each black area of an effective screen displaying the two consecutive frames, perform recognition of a characteristic of the frame at least by performing recognition of the characteristic of the frame based on a deep learning model, determine a change ratio of the detected black areas of the two consecutive frames, identify whether the image is a still image or a moving image based on the identified characteristic of the frame and comparing the determined change ratio of the detected black area of the effective screen of the two consecutive frames to a third threshold, and display the frame of the two consecutive frames based on the identifying whether the image is a still image or a moving image and a predetermined image quality mode of a still image or a moving image; and
based on the ratio of the identified size of the area to the size of the frame being less than the second threshold, display the frame based on the predetermined image quality mode of the still image without performing the recognition of the characteristic of the image and the detecting of each black area of the effective screen displaying the two consecutive frames,
wherein the image is determined to be a still image based on the change of the detected black area of the effective screen of the two consecutive frames being equal to or greater than the third threshold and the identified characteristic of the frame indicating that the image includes a user interface.
