CYLINDRICAL PROJECTED PICTURE GENERATION METHOD, PROGRAM, AND CYLINDRICAL PROJECTED PICTURE GENERATION DEVICE

An exfoliated picture projection method and device are provided which are capable of outputting distortion information of three-dimensional picture data. A distortion amount is calculated in accordance with the difference between the position of a reference virtual ray and the position of a virtual ray projected during creating of the exfoliated picture, coloring is added to the virtual rays in accordance with the distortion amount, and the colored virtual rays are projected to generate exfoliated picture data. Then, the same virtual rays are projected to generate perspective projective picture data, and the exfoliated picture data and perspective projective picture data are subjected to post processing. Therefore, the obtained exfoliated picture and perspective projection picture are output to a monitor.
