Abstract(in English) This paper presents development and evaluation of a multi-primary image projector. Our projector is primarily configured with a light source component and an image projection component. The light source, which can be programmed by using a computer, can reproduce any spectral curves. Spatial images are projected by a digital mirror device (DMD) chip that provides rapid control of the intensity of the light source spectra. The multi-primary images are reproduced by multiplexing the time-sequential 2D image pattern projections with various primary illuminant spectra. In this paper, we introduce wide gamut image projection and spectral image projection techniques based on optimal spectral light source designs. In addition, as its application to imaging technologies, we introduce a one-shot-type measurement technique for camera spectral sensitivities and a geometric calibration technique for projected images.
