Abstract: In an example embodiment, a system for creating a display from multiple projectors receives as an input a source pixel derived from an image to be displayed. The system generates a scalar-adjusted pixel by applying a scalar for an adjustment range to each channel value in the source pixel, where the scalar depends on whether the source pixel is gray or color. The system modifies each channel value in the scalar-adjusted pixel according to a luminance adjustment curve for a projector, where the luminance adjustment curve depends on whether the source pixel is gray or color. The system generates the luminance adjustment curve from captured calibration images by: (1) creating an interpolated response curve; and (2) generating and inverting a median difference curve based on the interpolated response curve for the projector and the interpolated response curves for the other projectors in the system.
