AI Technical Summary
Technical Problem
Existing lighting technologies are limited by preset settings and physical constraints, restricting the flexibility and speed of lighting design possibilities, especially in projector systems.
Method used
A method and device that utilize a two-dimensional pattern retrieval and real-time conversion system, allowing control of commercially available digital projectors via standardized protocols like DMX512 or ArtNet, with adjustable brightness, shape, and color, and synchronization of multiple projectors to create dynamic lighting scenarios.
Benefits of technology
Enables flexible and real-time lighting design independent of preset settings, maintaining easy controllability and high-quality transitions between lighting scenarios, even with unsynchronized projectors.

Abstract
The present invention relates to a method and an apparatus for emulating a floodlight partially covered with a mask. In order to realize a lighting design that does not depend on any preset in a floodlight by using low-cost and readily available lighting technology components while maintaining the existing lighting technology control protocol, it is proposed that a two-dimensional pattern is retrieved from a pattern memory 4 depending on the pattern channel value of the lighting technology control protocol, and transformed depending on the transformation channel value of the lighting technology control protocol, and then the transformed pattern is transformed into a raster image, in which the pattern pixels of the raster image are 20% brighter than the remaining non-pattern pixels, and the raster image is output by a digital projector 8 as a floodlight.
