Stereoscopic image drawing apparatus and drawing method

A stereoscopic image drawing apparatus comprising:

• a storage unit which stores data including at least data concerning a multiple viewpoint cameras, data concerning a shape of a drawing object, data concerning ranges of a distant view region and a close view region, and data concerning a procedure of drawing processing, and which includes an memory;
• a distant view image generation unit which reads data needed to draw an image of computer graphics from the storage unit, generates a distant view image as a projection image of a drawing object existing in the distant view region by using one camera disposed near a center position of the multiple viewpoint cameras, and writes one distant view image thus generated into the memory in the storage unit;
• a close view image generation unit which reads data needed to draw an image of computer graphics from the storage unit, generates a close view image as a projection image of a drawing object existing in the close view region by using one camera disposed near a center position of the multiple viewpoint cameras, and writes one close view image thus generated into the memory in the storage unit;
• a distant view board drawing unit which reads the distant view image of the drawing object in the distant view region generated by the distant view image generation unit from the storage unit, sticks the distant view image so as to cover whole of a tetragon model of computer graphics serving as a distant view board, then draws projection images of the tetragon model by using cameras included in the multiple viewpoint cameras, and writes a plurality of projection images thus drawn into the memory in the storage unit;
• an intermediate view image drawing unit which reads data needed to draw a stereoscopic image of computer graphics from the storage unit, draws projection images of a drawing object in an intermediate region located between the distant view region and the close view region by using cameras included in the multiple viewpoint cameras, and writes a plurality of projection images thus drawn into the memory in the storage unit;
• a close view board drawing unit which reads the close view image of the drawing object in the close view region generated by the close view image generation unit from the storage unit, sticks the close view image so as to cover whole of a tetragon model of computer graphics serving as a close view board, then draws projection images of the tetragon model by using cameras included in the multiple viewpoint cameras, and writes a plurality of projection images thus drawn into the memory in the storage unit;
• a pixel arrangement conversion unit which reads a plurality of projection images drawn by the distant view board drawing unit, the intermediate view image drawing unit and the close view board drawing unit from the memory in the storage unit, rearranges pixel arrangements, converts the projection images to images having a form to make stereoscopic display possible, and writes resultant images into the storage unit;
• and
• presentation unit which reads the images having a form to make stereoscopic display possible generated by the pixel arrangement conversion unit from the storage unit, and presents the images to a viewer.
