1. A display apparatus, comprising:
a receiver configured to receive input image data;
an accumulator configured to generate a cumulative data count by analyzing a degree of degradation according to the received input image data and a burn-in factor;
an interpolator configured to update the cumulative data count in a memory by applying an adaptive weight to the generated cumulative data count; and
a compensator configured to generate compensation data using the input image data and the updated cumulative data count,
wherein, in the update of the cumulative data count, the interpolator is configured to assign a reduced weight to an accumulated count value as time continues.
