Multidimensional interpolation device, multi-dimensional interpolation method, and computer program

摘要

PPROBLEM TO BE SOLVED: To easily materialize a rapid interpolational process such as conversion in color space and the like in as small circuit structure as possible. PSOLUTION: An N-dimensional digital image signal 205 is divided to a higher bit signal 212 and a lower bit signal 214 by means of a data divider 210. A referential value corresponding to all the combination of the divided higher bit signal is divisionally stored without overlapping into 2SPN-1/SPpieces of submemories (multi-dimensional LUT 260), and at the same time (N+1) pieces of referential values necessary for the interpolational process are simultaneously read out by a referential-value reader 250. As a result, the interpolational process can be rapidly performed, and an address can be produced without divider for accessing to the submemory. Therefore, the interpolational process at high speed such as the conversion in color space and the like can be materialized in as small circuit structure as possible. PCOPYRIGHT: (C)2010,JPO&INPIT
