Abstract: A white balance correcting apparatus and a white balance correcting method are provided. A white balance correcting apparatus includes a white balance corrector configured to divide an input image into a plurality of blocks, determine, using a reference color temperature line, adjusted color temperatures of blocks included in a white area among the plurality of blocks, and calculate red (R) and blue (B) gains to which different weights are applied according to the adjusted color temperatures of the blocks.

Abstract: Disclosed herein is a method and apparatus for processing a thermal image. The method includes: performing histogram stretching on thermal image data of the thermal image; and adjusting a histogram stretching scale for thermal image data of a next frame using histogram data of the thermal image data on which the histogram stretching is performed. As a result, it is possible to mitigate that an image becomes less recognizable as thermal image data is deteriorated or saturated.
