1. An image processing apparatus comprising: circuitry configured to select one frame of an image compositing target section; calculate (i) a first ratio of an overlapped area (C) of the selected frame and a composited image that includes at least two overlaid frames to an area (A) of the at least two overlaid frames and (ii) a second ratio of the overlapped area (C) to an area (B) of the selected frame; and add the selected frame, as a compositing target image, to the composited image in a case the second ratio is greater than the first ratio and the second ratio is less than a threshold, and not add the selected frame to the composited image in a case the second ratio is greater than or equal to the threshold.
