The present invention relates to a 3-D data storing method, and more particularly to a 3-D data storing method capable of accessing the data of eight cubical vertices belonging to a cube during a memory access cycle.
The term 3-D data refers to data groups which are arranged in a mesh structure. This arrangement is chiefly used for color correction in a color television. For interpolating a color value of a point around a known point in the color space expressed by the three primary colors, i.e. red, green and blue, the color values of the known point and eight cubical vertices surrounding the known point should be known.
According to a conventional method, the 3-D data is sequentially stored in a single memory, thus requiring eight memory accessing operations for reading the color values of the eight cubical vertices. That is, to acquire the data of the cubical vertices of a cube, eight memory accessing operations are required. Such a conventional method limits the operating speed of a system for processing 3-D data, thus making real-time processing difficult.
