An image processing apparatus that generates, from a captured image, a color temperature map that indicates color temperature information of light illuminating a captured scene for each area, is disclosed. The apparatus determines, for each area of the captured image, either an interactive light source that has a communication function, a non-interactive light source that does not have a communication function, or both of the interactive light source and the non-interactive light source is a light source that illuminates a corresponding area in the captured scene. The apparatus also generates the color temperature map using a result of determination made by the determining unit, color temperature information acquired from the interactive light source through communication, and color temperature information of the non-interactive light source that is estimated based on the captured image.
