Solution Overview
Problem
Conventional scenographic projection techniques are limited by the color of light bulbs and lack advanced dynamic range capabilities, resulting in restricted color saturation, contrast, and visual effects in applications such as amusement parks and theater productions.
Innovation Solution
A high dynamic range scenographic image projection system that uses multiple projectors to align patterned light with optical patterns on objects, enhancing hue, contrast, and saturation by projecting images onto objects to alter their visual and non-visual features, including the use of color correction and blending techniques to achieve realistic and dynamic lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting techniques with colored bulbs are used, then the lighting system is simple and easy to operate, but the color saturation, contrast, and dynamic range are limited
Solution Approach 1:
The patent combines multiple projectors with different color capabilities (including RGB and white light projectors) to create a unified lighting system that achieves high color saturation and dynamic range. By merging the output of multiple projectors onto the same target area, the system overcomes the limitations of single-bulb color constraints while maintaining operational simplicity through centralized control.
Solution Approach 2:
The system employs projectors that can function in multiple modes - some projectors can project colored images while others project white light, and all can be controlled to achieve various lighting effects. This multi-functionality allows the system to adapt to different scenographic requirements without requiring separate specialized lighting equipment for each effect.
2Illumination intensity
If multiple projectors are used to enhance color saturation and contrast, then the visual effects are improved, but the system complexity and alignment requirements increase
Solution Approach 1:
The patent applies different lighting characteristics to different spatial regions by positioning projectors at specific locations and angles. Each projector is configured to illuminate particular areas with optimized color saturation and contrast settings, allowing the system to achieve high visual quality without requiring uniform complexity across the entire system.
Solution Approach 2:
The system uses multiple projectors to project identical or complementary images onto the same target surface from different positions. This copying approach ensures consistent visual effects across multiple projection sources while simplifying the control system, as the same image content can be distributed to multiple projectors rather than requiring complex coordinate transformations for each.
3Manufacturing precision
If patterned light is aligned with optical patterns on objects, then the visual realism is enhanced, but the precision requirements and difficulty of detection increase
Solution Approach 1:
The system performs preliminary alignment by projecting test patterns or reference marks before the actual scenographic projection. This preliminary action allows operators to verify that patterned light aligns correctly with optical patterns on objects, ensuring high visual realism while simplifying the detection process through pre-established reference points.
Solution Approach 2:
The patent utilizes color variations in the projected patterned light to enhance the alignment with optical patterns on objects. By matching the color characteristics of the projected light with the inherent optical properties of the object surfaces, the system achieves realistic visual effects while making alignment verification easier through color correlation rather than requiring precise geometric measurement alone.

AI summary
A high dynamic range scenographic image and video projection system and method involving the projection of an image of an object or collection of objects onto the object, 2D or 3D, in such a manner than projected image elements are positioned substantially on the actual image of the object. The projection enhances or otherwise alters the hue, contrast, brightness, saturation, luminance, and/or other visible features of the object. Visual and not-visual features may be projected onto the object or the area around the object to enhance or disguise the object as well as the surroundings of the object.
