Techniques, systems and apparatus are described for adjusting auto white balance (AWB). An AWB adjusting device includes a map setting unit to perform map-setting on a number of light-source boxes that is at least M times greater than a number of registers by performing map-switching. M is an integer greater than or equal to 2. The AWB adjusting device includes a pixel counting unit for counting a number of white pixels of a standard image contained in each light-source box with map-setting. The AWB adjusting device includes a light-source selection unit to select a light source based on a maximum light-source box selected from the number of light-source boxes having a greatest number of the white pixels. The AWB adjusting device includes a balance gain applying unit to calculate a red gain and a blue gain based on a mapping value of the maximum light-source box to adjust AWB. |
