Abstract

We evaluate, analyse and propose improvements to a previously published end-user calibration method for projection devices (Bala and Braun, CIC 2006). We focus on the estimation of the displays tone response curve, using only an uncalibrated consumercamera. The results show that the method is accurate, depending on both the projector and the camera used. We found that the method is accurate enough for most end-user applications. A weakness of this method is the wrong estimation of the projectors black level, which significantly affects the estimation of the camera response curve.
