An example of an information processing system includes a moving object including a camera and including a white area in an exterior of the moving object. An image capturing range of the camera includes the white area. It is determined whether or not each of pixels in a preset specified area that includes the white area in an image captured by the camera is white, and if the number of pixels that are white according to the white determination exceeds a predetermined number, white balance is performed to adjust the pixels that are white according to the white determination in the specified area closer to white.
