Re-photography is used to observe the time-series change. It means taking a photo again with the same shooting position and composition as a certain landscape photograph (hereafter referred to as the base photograph). Currently, various techniques are developed to perform highly accurate re-photography. These technologies have the disadvantage that the equipment cost greatly, or that the photographer requires special skills. In order to solve these problems, the mobile terminal applications for re-photography are developed. But these applications have problems caused by difference in angle of view between the base photograph and the mobile terminal. In this paper, in order to deal with the problems, we proposed an application with the view angle adjustment function. We also showed that the application can solve the difference in angle of view with respect to the shooting position and composition, by performing an evaluation experiment.
