Abstract: A white balancing device and a method of driving the same are provided. The white balancing device includes a map generator and an automatic white balancing (AWB) block. The map generator is configured to generate an indoor-outdoor map comparing a first image and a second image generated by performing a wide dynamic range (WDR) algorithm on the first image. The AWB block is configured to generate a first white point with respect to an outdoor region and a second white point with respect to an indoor region using the indoor-outdoor map.
