A white balance adjustment apparatus which is input image data acquired by an imager element to adjust a balance among color signals of the image data of a present frame includes an evaluation acquisition unit configured to acquire a plurality of groups of color signal data at each pixel position, as evaluation values, from the image data of the present frame and image data of at least one previous frame which is acquired before the present frame. The evaluation value acquisition unit includes an overlap area detection unit configured to detect image areas overlapping with each other between the image data of the at least one previous frame and the image data of the present frame. The evaluation values to be acquired from the image data of the at least one previous frame are selectively acquired in response to a detection result from the overlap area detection unit.
