PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240288759 titled 'PROJECTOR
Simplified Explanation: The patent application describes a projector that uses a relay system to reduce the luminous flux width of one color light before combining it with another color light to project a combined image. The system includes a detection unit to measure the f-number of the projection system and a control unit to adjust the white balance of the projection image based on this measurement.
Key Features and Innovation:
- Relay system reduces luminous flux width of one color light
- Light combining prism merges two color lights for projection
- Detection unit measures f-number of projection system
- Control unit adjusts white balance based on f-number measurement
- Different pixel pitches for light modulation elements
Potential Applications: This technology can be used in various projection systems, such as in home theaters, classrooms, and business presentations.
Problems Solved: This technology addresses issues related to color balance and image quality in projection systems by dynamically adjusting the white balance based on the f-number of the system.
Benefits:
- Improved color balance in projected images
- Enhanced image quality
- Dynamic adjustment for optimal viewing experience
Commercial Applications: Title: Dynamic White Balance Adjustment in Projection Systems This technology can be applied in the development of advanced projectors for commercial and consumer use, improving the overall viewing experience and image quality.
Prior Art: Readers can explore prior art related to projection systems, color balance technologies, and image processing methods to understand the evolution of this innovation.
Frequently Updated Research: Researchers are constantly exploring new ways to enhance color accuracy and image quality in projection systems, which may lead to further advancements in this technology.
Questions about the Technology: 1. How does the relay system in the projector reduce the luminous flux width of the color light? 2. What are the specific benefits of adjusting the white balance based on the f-number of the projection system?
Original Abstract Submitted
a projector includes a relay system reducing a luminous flux width of a first color light modulated by a first light modulation element, a light combining prism outputting a combined light formed by combining the first color light having the luminous flux width reduced by the relay system and another color light modulated by a second light modulation element, a projection system projecting the combined light as a projection image, a detection unit detecting an f-number of the projection system, and a control unit correcting a white balance of the projection image by controlling an amount of a light output from at least one of the first light modulation element and the second light modulation element based on the f-number detected by the detection unit. a pixel pitch of the first light modulation element is larger than a pixel pitch of the second light modulation element.
