摘要:
Provided is an image generation device generating a high-quality image of an object under a pseudo light source at any desired position, based on geometric parameters generated from a low-quality image of the object. The image generation device includes: a geometric parameter calculation unit that calculates a first geometric parameter regarding a shape of a surface from light source position, viewpoint position, and geometric normal information regarding the shape; a high-resolution database unit that stores an exemplum indicating a mesostructure of a portion of the surface and has a spatial resolution higher than the geometric normal information; an exemplum expansion unit that increases the exempla to be spatially expanded; a geometric parameter modification unit that modifies the first geometric parameter using the increased exempla; and an image generation unit that generates an output image by applying the modified geometric parameter to a reflection model.

An image processing method eliminates the seams between adjacent projectors in a multi-projector autostereoscopic display system. The abutting views of two adjacent projectors are overlapped. The image generator shows the same image in the overlapped views, so that the viewer cannot see the seam.

Provided is an image generation device generating a high-quality image of an object under a pseudo light source at any desired position, based on geometric parameters generated from a low-quality image of the object. The image generation device includes: a geometric parameter calculation unit (102) that calculates a first geometric parameter regarding a surface structure from light source position, viewpoint position, and geometric normal information regarding the surface structure; a high-resolution database unit (103) that stores an exemplum indicating a mesostructure of a portion of the surface and has a spatial resolution higher than the geometric normal information; an exemplum expansion unit (104) that increases the exempla to be spatially expanded; a geometric parameter modification unit (105) that modifies the first geometric parameter using the increased exempla; and an image generation unit (106) that generates an output image by applying the modified geometric parameter to a reflection model.
