1. A signal processing apparatus comprising: circuitry configured to detect a position corresponding to a first image within a wide angle image; process the wide angle image by changing a center of the wide angle image so that the center of the wide angle image coincides with the position corresponding to the first image; and control a display to display the first image and the processed wide angle image, wherein the wide angle image includes an area corresponding to the first image, when an image direction corresponding to the first image is changed, the wide angle image is processed so that the changed first image corresponds to an area at the center of the processed wide angle image, the wide angle image is a 360 degree image, and a view angle of the wide angle image is not changed when the image direction corresponding to the first image is changed.
