ABSTRACT:
There is provided a white balance control method. A color space coordinate expressing a color signal of each divided block is transformed into a white balance determination space coordinate. A light source estimation area and a high-saturation determination area are set in a white balance determination space to which the transformed white balance determination space coordinate belongs. A kind of the light source is estimated based on a white balance determination space coordinate distribution in the light source estimation area. A kind of the light source is determined based on the estimated kind of the light source and a white balance determination space coordinate distribution in the high-saturation determination area. White balance control information is calculated based on the determined kind of the light source. White balance control with respect to an image signal is carried out based on the calculated white balance control information.
