Patent ID: 7116339

Claim:
An image rendering method, comprising: a) determining a number of times M that a predetermined interpolation calculation is to be carried out to obtain a desired image effect; b) providing an initial calculation parameter used in the predetermined interpolation calculation; c) performing the predetermined interpolation calculation a first time based upon the initial calculation parameter to produce a plurality of result parameters; d) performing the predetermined interpolation calculation one additional time after replacing the initial calculation parameter with one of the result parameters of the first predetermined interpolation calculation to produce a plurality of result parameters of the additional predetermined interpolation calculation; and e) performing the predetermined interpolation calculation (M−2) additional times, each one being performed after replacing the calculation parameter used in its immediately preceding predetermined interpolation calculation with one of the result parameters of the immediately preceding predetermined interpolation calculation to produce a plurality of result parameters of the current predetermined interpolation calculation, thereby obtaining the desired image effect.
