Abstract: There is provided a generation device, an identification information generation method, a reproduction device, and an image reproduction method capable of identifying a packing scheme. Stereo packing identification information for identifying a scheme of packing is generated with regard to a plurality of region images of a celestial sphere image packed in a packed frame. In a case in which packing is performed by one of a plurality of packing schemes, stereo packing identification information indicating a packing method can be generated, a projected frame can be generated easily on the basis of the identification information, and the projected frame can be rendered. The present technology can be applied to a case in which a celestial sphere stereoscopic image is transmitted to be reproduced on a reception side.
