Angular Image Processing for Glossy HDR Display Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High dynamic range (HDR) displays struggle to produce a glossy effect (kirameki effect) and require further optimization of light profiles for satisfactory visual effects.
Innovation Solution
An image processing method that includes filtering noise, image compensation, and image discontinuity reduction to generate processed image data, which is then output to a display system comprising a camera, image processing device, and display module to enhance the glossy effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If HDR display technology is used to present high contrast images, then both bright and dark details can be clearly presented, but the glossy effect (kirameki effect) that occurs when real light hits an object cannot be produced
Solution Approach 1:
The patent segments the light field data into multiple angular profiles corresponding to different viewing positions. By dividing the light distribution into discrete angular segments and processing each separately, the system can preserve realistic glossy effects while maintaining HDR brightness contrast capabilities.
Solution Approach 2:
The patent adds an angular dimension to the traditional 2D image data by incorporating light field information with multiple angular profiles. This dimensional expansion enables the display to represent glossy effects and viewing-angle-dependent properties that cannot be achieved with conventional 2D HDR displays.
2Reliability
If the display presents a glossy and realistic effect, then visual quality improves, but the light profile of the image needs further processing or optimization
Solution Approach 1:
The patent performs preliminary processing of the light field data before display, including noise filtering, image compensation, and discontinuity reduction. By preprocessing the angular profile data and generating optimized processed image data in advance, the system reduces the complexity of real-time processing requirements while maintaining glossy effect quality.
Solution Approach 2:
The patent introduces an image processing device as an intermediary between the light field capture and display. This intermediary component handles the complex light profile processing, noise filtering, and optimization tasks, separating the complexity from the display system itself and enabling glossy effect generation without burdening the display hardware.
3Reliability
If noise filtering and image processing are applied to angular profile data, then visual quality improves, but processing time and computational resources increase
Solution Approach 1:
The patent applies selective processing to the angular profile data, focusing computational resources on critical aspects such as noise filtering and discontinuity reduction where they provide the most benefit. By applying partial processing rather than exhaustive processing to all data aspects, the system improves image quality while controlling processing time.
