Electronic apparatus and controlling method thereof

A method for controlling an electronic apparatus, the method comprising:

• obtaining two consecutive frames of an input image as input frames, the two consecutive frames corresponding to a first frame and a second frame preceding the first frame;
• obtaining a first interpolation frame corresponding to a first motion vector of the input frames and a first confidence corresponding to the first interpolation frame based on a first interpolation method;
• obtaining a second motion vector corresponding to down-sampled frames of the input frames based on a second interpolation method that is different from the first interpolation method;
• obtaining a second interpolation frame corresponding to the second motion vector of the input frames and a second confidence corresponding to the second interpolation frame-based on the second interpolation method that is different from the first interpolation method;
• obtaining an up-sampled frame of the second interpolation frame and a second confidence corresponding to the second interpolation frame based on the second interpolation method;
• obtaining weights corresponding to the first interpolation frame and the second interpolation frame, based on the first confidence and the second confidence, respectively;
• obtain a combined interpolation frame based on an up-sampled frame of the first interpolation frame, the up-sampled frame of the second interpolation frame, and the weights;
• and
• obtaining an output image based on the first frame, the second frame, and the combined interpolation frame.
