1. An apparatus for generating a panorama image, the apparatus comprising:
a Region Of Interest (ROI) selecting block configured to receive a plurality of images and configured to output ROI images by selecting an ROI of each of the plurality of images;
a High Dynamic Range (HDR) processing block configured to perform HDR processing on the ROI images; and
a panorama image generating block configured to:
divide a high frequency image corresponding to one ROI image among the ROI images, on which the HDR processing is performed, into a plurality of image regions;
select a main image region among the plurality of image regions;
select a matching point of high frequency images corresponding to the ROI images by mapping the main image region to each of the high frequency images, wherein the matching point is a region having a highest correlation between the main image region and each of the high frequency images;
search for a matching coordinate of the ROI images based on the matching point; and
generate a panorama image by stitching the plurality of images based on the matching coordinate,
wherein the HDR processing block is further configured to perform the HDR processing on the panorama image.
