1. An image display apparatus comprising:
a display;
a memory storing at least one instruction; and
a processor configured to execute at least one instruction stored in the memory to:
estimate a blur level of each sub-area of a plurality of sub-areas included in a first image; and
improve a resolution of at least one sub-area of the plurality of sub-areas, based on an estimated blur level of the at least one sub-area,
wherein the display is configured to output a second image including the at least one sub-area having the improved resolution, and
wherein the processor is further configured to execute the at least one instruction to:
split the first image into the plurality of sub-areas in a spatial domain;
transform each sub-area of the plurality of sub-areas into a frequency domain, and estimate the blur level of each sub-area of the plurality of sub-areas in the frequency domain; and
improve the resolution of the at least one sub-area in the spatial domain.
