ABSTRACT:
A parameter setting unit sets a parameter used in a predetermined interpolation calculation. A calculating unit performs the predetermined interpolation calculation based upon an input parameter. A feedback unit feeds back a value obtained through the predetermined interpolation calculation to the parameter setting unit. Then, the parameter setting unit resets the parameter based upon the value obtained through the predetermined interpolation calculation. Accordingly, an image rendering apparatus easily implements nonlinear interpolation by DDA processing which performs linear interpolation using polygon node coordinates in, for example, computer graphics, and implements rendering of, for example, curved line portions quickly and with light processing loads.
