Abstract: In an example embodiment, a system for creating a display from multiple projectors receives as an input a source pixel derived from an image to be displayed. The system generates a scalar-adjusted pixel by applying a scalar for an adjustment range to each channel value in the source pixel, where the scalar depends on whether the source pixel is gray or color. The system modifies each channel value in the scalar-adjusted pixel according to a luminance adjustment curve for a projector, where the luminance adjustment curve depends on whether the source pixel is gray or color. The system generates the luminance adjustment curve from captured calibration images by: (1) creating an interpolated response curve; and (2) generating and inverting a median difference curve based on the interpolated response curve for the projector and the interpolated response curves for the other projectors in the system.

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: In an example embodiment, a calibration module in a projector platform establishes an initial configuration of settable exposure attributes for a digital camera. The calibration module projects a preview image onto a surface and captures the projection of the preview image with the digital camera and receives input from a user identifying regions of interest in the capture of the preview image. Next the calibration module projects an exposure image onto the surface. The calibration module then computes a final configuration of exposure attributes for the digital camera by iteratively: (a) capturing the projection of the exposure image with the digital camera; (b) measuring descriptive statistics relating to the color channels of pixels in the regions of interest in the capture of the exposure image; (c) evaluating the descriptive statistics with an evaluation function determined by a calibration process; and (d) establishing a revised configuration of exposure attributes.
