Abstract: In order to form an image by projecting a texture 520 at an arbitrary angle to an arbitrary position on a surface of an object 500 represented as a 3D model, texture data 520 is divided into texture lines 530 having a width of one dot and a length equal to the number of dots on one side of the texture. Then, supposed is a stereoscopic object 540 based on one texture line 530 that the texture line is extended in a light travel direction while possessing color information from an arrangement relationship between the texture line 530, object model 500 and virtual light source in the three dimensional space. The intersecting part 510 between the stereoscopic object 540 and the surface of the object model 500 is defined as a region for rendering the texture line, and thereby a stereoscopic object 540 is rendered onto the defined region.

Abstract: A color correction device and method separates achromatic color from chromatic color and independently controls the color. Color interpolation is performed along the locus of the color change of an input signal by dividing a color space of the input signal into blocks to surely include the locus changing from black to white passing through a center part based on the locus (chromatic locus) changing from black to white surrounding a color region to be handled by an input image equipment and the locus (achromatic locus) changing from black to white passing through the center part of the color region to be handled by the input image equipment. An achromatic part present in the center part of the color space is separately handled from a chromatic part present in its peripheral part.
