High color-fidelity display using a modified projector

A high color-fidelity display provides accurate spectral reproduction to reduce observer metamerism. In this poster, we implement a multispectral projection display using a modified projector. The modification only requires adding a lens array on the projection optical path to creates multiple copies of images and using color filters to create new primaries. To produce the new primaries with high throughput and low correlation, we proposed a volume maximization-based filter selection approach. We also present an efficient multispectral rendering algorithm to compute the input values of each primary. The experiments show that our multispectral display can accurately approximate desired multispectral images and effectively reduce observer metamerism when compared with the original three primaries projection display.
