1. An electronic apparatus configured to perform downscaling comprising:
a memory storing an input image; and
at least one processor configured to:
apply a filter to the input image to identify the input image as a plurality of areas,
apply a first low-frequency filter to a first area among the plurality of areas, and
apply a second low-frequency filter to a second area among the plurality of areas,
wherein a cut-off frequency of the second low-frequency filter is higher than a cut-off frequency of the first low-frequency filter,
wherein at least one of the cut-off frequency of the first low-frequency filter and the cut-off frequency of the second low-frequency filter is determined based on a downscaling ratio with respect to the input image.
