Abstract:
1. A device for generating an objective interpolation value from a look up table including a plurality of position data that are stored in a plurality of regions defined by a plurality of rows and a plurality of columns, the device comprising: a first multiplying part that multiplies a square value of a column component of the objective interpolation value by an operating value to generate a first multiplied value, the operating value being wherein Δy and Δ represent a difference between a first interpolation value of a first row and the objective interpolation value and a distance between gray-scales of a first column and a second column, respectively, p a second multiplying part that multiplies the column component by the operating value to generate a second multiplied value; and an adding part that sums up the first multiplied value, the second multiplied value and the operating value so as to generate the objective interpolation value.
