Patent ID: 11922607
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An electronic device comprising:
a display;
a memory; and
at least one processor electrically connected with the memory,
wherein the memory stores instructions that, when executed, cause one or more of the at least one processor to control the electronic device to:
identify an event for displaying a thumbnail image of image content on the display before outputting the image content, the thumbnail image corresponding to at least one frame of image content;
based on identifying the event, display the thumbnail image,
wherein, to display the thumbnail image, the instructions cause one or more of the at least one processor to control the electronic device to:
determine whether the image content is a high dynamic range (HDR) image;
based on determining that the image content is the HDR image, obtain maximum brightness information of the image content based on metadata of the image content, determine a normalizing factor based the maximum brightness information, perform tone mapping with respect to the at least one frame of the image content based on the normalizing factor, and control the display to output the thumbnail image using the at least one frame after the tone mapping is performed with respect to the at least one frame; and
based on determining that the image content is not the HDR image, control the display to output the thumbnail image using the at least one frame of the image content without performing the tone mapping based on the normalizing factor,

wherein the instructions, when executed, cause one or more of the at least one processor to:
determine whether the maximum brightness information satisfies a first condition;
determine the normalizing factor according to a first operation based on the maximum brightness information being determined to satisfy the first condition or according to a second operation different from the first operation based on the maximum brightness information being determined to not satisfy the first condition, and

wherein the first operation comprises determining the normalizing factor based on the maximum brightness information.
