For consumer imaging applications, multi-spectral color refers to capturing and displaying images in more than three primary colors in order to achieve color gamuts significantly larger than those produced by RGB devices. In this paper, we describe the building of both a multi-camera recording system and multi-projector display system using off-the-shelf components that, unlike existing multi-camera/projector systems that rely on expensive and time consuming optical alignment of camera/projector views, relies upon the virtual alignment of views performed in software. Once images are properly aligned, the described systems represent recording/display platforms that scale linearly in cost with the number of color primaries where new colors are added by simply attaching more devices. In this paper, we illustrate frames of the color video produced using a five camera system as well as an image of the aligned six projectors of the display system.
