Claim 7:
8. 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 of the input image to acquire a downscaled first image,
apply a second low-frequency filter to a second area among the plurality of areas of the input image to acquire a downscaled second image,
apply a pattern detection filter to the input image to acquire a weight value for identifying the plurality of areas, and
apply the acquired weight value to the downscaled first image and apply another weight value acquired based on the acquired weight value to the downscaled second image to acquire the downscaled image,
wherein a cut-off frequency of the second low-frequency filter is higher than a cut-off frequency of the first low-frequency filter.
