1. A display apparatus comprising: a display; and a processor configured to detect an object in an input image, divide the image into a first region of the image corresponding to a location of the detected object and a second region of the image corresponding to a region of the input image excluding the first region, adjust the first region and the second region using different scale factors, and control the display to display the image having the adjusted first and second regions, wherein a frame of the input image comprises a plurality of regions having a same size, wherein the first region comprises one or more regions among the plurality of regions having the same size, wherein the first region is scaled using a scaling factor less than 1, wherein the second region comprises a plurality of regions among the plurality of regions having the same size excluding the one or more regions of the first region, wherein the plurality of regions of the second region are scaled using a scale factor greater than the scale factor of the first region, wherein a region among the plurality of regions of the second region farther from the first region is scaled using a greater scale factor than another region among the plurality of regions of the second region closer to the first region, wherein the processor is further configured to scale up the first region using a predetermined scale factor and scale down the second region based on a predetermined scale factor, and wherein the predetermined scale factor is a scale factor corresponding to a Gaussian distribution.
