Emerging next generation digital light projectors are using multiple LED/laser sources instead of one white lamp. This results in a color gamut much larger than any existing display or capture device. Though advantageous in theory, when used to display contents captured/processed at a smaller gamut, a large gamut expansion results in hue-shift artifacts. We present a hardware-assisted 3D gamut reshaping method that handles the gamut expansion in LED based DLP displays by hierarchical temporal multiplexing of the multiple primaries. This, in turn, results in a color emulation technique by which projectors with such large gamuts can also achieve a standard color gamut and white point - the two most important color properties in terms of display quality, with an additional advantage of increased brightness and dynamic range. The same method can also be used for color balancing across multiple projectors that are often used to create large-scale high resolution displays.
