Abstract
The present specification is related to a method for performing multi-projection and a multi-projection system for minimizing a black offset in a multi-projection environment. The present specification provides the method for performing multi-projection comprising estimating the intensity transfer function (ITF) of a plurality of projectors, calculating an optimal black offset threshold for each of the projectors by using each of the ITFs, and applying the optimal black offset threshold to an image projection by each of the projectors.
