Dual modulation using concurrent portions of luminance patterns in temporal fields

摘要

Embodiments of the invention facilitate high-dynamic-range (HDR) imaging by generating portions of spatial and/or temporal luminance patterns with different spectral power distributions substantially concurrent with, for example, the modulation of the light intensity associated with the portions of luminance patterns. The method can include predicting luminance patterns associated with multiple spectral power distributions. The method also can include distributing portions of the luminance patterns in one or more temporal fields. In some embodiments, distributing the portions of the luminance patterns can include interlacing those portions. Further, the method can include modulating light intensities of the luminance patterns to produce an age with other spectral power distributions. In some embodiments, the distribution of the luminance pattern portions can be substantially synchronous with modulating the light intensity of the luminance patterns.

1. A method of generating an image, the method comprising:
receiving input image data; predicting a first luminance pattern and a second luminance pattern for a first spectral power distribution and a second spectral power distribution, respectively, said first luminance pattern and said second luminance pattern generated from said input image data and comprise a low resolution version of said input image data; distributing portions of the first luminance pattern and portions of the second luminance pattern in one or more temporal fields; interlacing the portions of the first luminance pattern and the portions of the second luminance pattern in the one or more temporal fields; and modulating light intensities of the first luminance pattern of the first spectral power distribution and the second luminance pattern of the second spectral power distribution to produce the image with other luminance patterns.
