Abstract
Techniques for use in a digital mirror device based luminaire. The techniques include using a filter as a gobo for definition.
Claims24
A processing system for a digitally-controllable light passing element, comprising:
- a memory, storing a digital file that represents a shape of light to be passed;
- a digital signal processor, which carries out, in operation, mathematical operations on said digital file;
- a transfer controller element, separate from said digital signal processor, which receives information about data to be moved, including start location of the data, and other information which enables the device to determine the data, and which obtains the data directly from the memory, processes it according to the requests, and returns the information to the memory, without intervention of the digital signal processor;
- and uses said information to modify said digital file;
- and
- a hardware block, which receives and interfaces commands from a remote controller.

A method of controlling a digital gobo, comprising:
- forming an image representing a gobo from a plurality of polygons;
- and
- using said image to control an electronic element to shape an output light.
A method of projecting light, comprising:
- forming an image which will be used as a gobo for said light, to shape an outer edge of said light;
- compressing said image;
- storing the compressed version of said image;
- and
- using said compressed version of said image to control an electronic element to shape said light.
2 more elements
A method of storing information for controlling a gobo, comprising:
- storing a first image representing a gobo shape;
- storing a second image, representing a filter used to distort the gobo shape and using said first and second images to control an electronic device to display an image.
A method of controlling a digital light controlling element, comprising:
- storing an image representation in a memory, said image representation indicating a basic gobo;
- modifying said image representation using a second gobo acting as a filter to form a modified image;
- and
- using the modified image to control the digital light controlling element, to display light.
