Abstract: An electronic device is provided. The electronic device includes communication circuitry configured to communicate with an external electronic device, a processor operatively connected with the communication circuitry, and a memory operatively connected with the processor. The memory may store instructions which, when executed, cause the processor to control the electronic device to: obtain environment information associated with a video playback environment of the external electronic device, decode a high dynamic range (HDR) video, perform color conversion of the decoded HDR video based on the environment information, encode the color-converted video into a standard dynamic range (SDR) format, and transmit the encoded video to the external electronic device via the communication circuitry.

Abstract: An apparatus and method for detecting a fake fingerprint is disclosed. The apparatus may divide an input fingerprint image into blocks, determine an image quality assessment (IQA) value associated with each block, determine a confidence value based on the IQA values using a confidence determination model, and determine whether an input fingerprint in the input fingerprint image is a fake fingerprint based on the determined confidence value.
