Stereoscopic image generation method and stereoscopic image generation system

A stereoscopic image generation method and a stereoscopic image generation system that can generate, from an original image, a stereoscopic image that allows the viewer to perceive a natural stereoscopic effect are provided. The method includes a region setting step of setting a plurality of regions in an original image, a characteristic information acquisition step of acquiring characteristic information for each of pixels constituting the original image, a depth information generation step of generating depth information for each of the pixels for each of the plurality of regions on the basis of the characteristic information, and a stereoscopic image generation step of generating a stereoscopic image in which the positions of the pixels are changed on the basis of the pieces of depth information.
