Black-Level Compensation in Multi-Projector Display Systems

摘要

In general, in one aspect, an embodiment features computer-readable media embodying instructions executable by a computer to perform a method comprising: receiving a pixel for an image to be projected upon a display surface by a plurality of projectors as a composite projection comprising a plurality of partially overlapping component projections each generated by one of the projectors; and selectively increasing a luminance value of the pixel based on the luminance value of the pixel, a location of the pixel in the composite projection, a predetermined black-point threshold value, and a predetermined black-level compensation value.
