Method and apparatus for seamless integration of multiple video projectors

摘要: Method and apparatus are provided for seamless integration of multiple video projectors. In addition to edge blending, projection artifacts in dark or black image regions caused by residual grays from non-perfect projector levels reduced. Overlapped non-overlapped areas the defined then minimum level signal is boosted without affecting bright portion order create uniform level. The smoothed overlapped area with blending techniques. resultant projected may be passed through a neutral density filter lower base now overlap non-overlap regions. also pass physical mask which hard edged graded aligned less than overall region that when used, smooths transition between
