Abstract

A practical colorimetric calibration method using tetrahedral interpolation techniques was proposed for electronic imaging devices not having accurate analytical models. By dividing color gamut into many tetrahedrons and using ilnear matrices, 3-D forward and backward transformations were performed without iterative calculation. To reduce the measurement points, a nonlinear interpolation technique was also proposed. These interpolation errors were simulated on hypothetical devices obeying known analytical models to avoid measurement error and the device stability problem. According to the simulations, a 33 × 33 × 33 look up table was enough to model the analytical models with color difference ΔE*uv≤0.5 at worst, and 5 × 5 × 5 colors were enough to predict the color of the output devices in practice.
