Multilayer control of gobo shape
View Patent ↗A control of gobos defend by records in the gobo. The gobos are formed by menued shapes.
1. A method comprising:
defining an image as specified numbers of bits of primary colors;
translating the image from a bit-based form which defines in terms of its primary colors, into chrominance and its luminance values indicative thereof;
dimming the image by reducing the luminance value while maintaining constant chrominance; and
reconverting the chrominance and luminance back into said bit based form.
2. A method as in claim 1 , further comprising using a digitally controllable pixel level device in the path of a light beam, and controlling said digitally controllable pixel level device using said bit-based form.
3. A method as in claim 2 , wherein said digitally controllable device is a digital mirror device.
4. A method as in claim 1 , further comprising apportioning said chrominance as bits between a total allotted number of bits.
5. A method as in claim 4 , wherein there are a total allotted number of 8 bits, and wherein two of the primary colors get three bits and the other of the primary color gets two bits for its chrominance.
6. A method as in claim 4 , further comprising assigning adjacent lines the same color values, and providing additional resolution of said color values by combining said color values.
7. A method as in claim 6 , further comprising modifying said image to maintain byte boundaries.
8. A method as in claim 1 , further comprising combining multiple images together to provide twice as many available bits for the combined lines.
