Electronic apparatus and control method thereof

A control method of an electronic apparatus, comprising:

• obtaining a low-frequency variation amount based on low-frequency information corresponding to a first frame and low-frequency information corresponding to a second frame;
• obtaining a high-frequency variation amount based on high-frequency information corresponding to the first frame and high-frequency information corresponding to the second frame;
• obtaining a weight based on a difference between the low-frequency variation amount and the high-frequency variation amount;
• applying the weight to a high-frequency frame corresponding to the second frame;
• obtaining an output frame corresponding to the second frame, based on the second frame and a high-frequency frame to which the weight is applied;
• and
• displaying the obtained output frame.

An electronic apparatus, comprising:

• a memory storing instructions, and
• a processor configured to execute the instructions to:
• obtain a low-frequency variation value based on low frequency information corresponding to a first frame and a second frame;
• obtain a high-frequency variation value based on high frequency information corresponding to the first frame and the second frame;
• determine a weight based on a difference between the high-frequency variation value and the low-frequency variation value;
• and
• generating an output frame corresponding to the second frame by applying the weight to a high-frequency frame corresponding to the second frame.
