Recover Illumination of Images Taken under Irradiation of DLP Projector
Shi Xu · Applied Mechanics and Materials · 2013
Nowadays, more and more DLP projectors are used as light sources in some kind of applications for they are programmable. DLP projectors are designed to match human eyes, therefore when we see projected images or videos through our eyes, our perception would match the source files very well. However, in case we use high-speed cameras, color of captured images may deviate a lot from our expectations. In this paper, we explain the difference at first. Then, a method to recover illumination in consecutively captured images is proposed. Application, in which DLP projectors are used as light sources and cameras are used as sensors, may benefit from this work.
