    Abstract: First, a delivery delay, i.e. the time it takes for a content to be captured and a representative frame made available (i.e. delivered), is determined. Second, a video capture interval, i.e. a minimum time delay requirement between stable captured content frames, is determined. In other words, the recycle time-period after which it is safe to change frame content during a capture interval without impacting a prior stable video frame in the pre-delivery stage is determined.

    Abstract: A method for correcting a projection from a plurality of digital projectors is provided. The method includes receiving as an input a matrix which maps each pixel to be projected to a captured pixel that includes a row value and a column value and detecting a shift with respect row or column values in the matrix. The method further includes determining attributes of the shift, wherein the attributes include a type for the shift and an overlap length for the shift. A gradient length is determined from the overlap length. A gradient of pixel weightings is generated for each gradient length. The pixel weightings are uniformly sloping and are associated with pixels in the gradient length and neighboring pixels. Intersecting gradients re merged and a list that includes common points and diagonal points is created from the merging process. The method operations may be embodied as code on a computer readable storage medium.
