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, utilizing a camera, image processing device, and display module to enhance the angular profile data of images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If HDR display technology is used to present images with high contrast, then both bright and dark details can be clearly presented, but the display cannot produce a glossy effect (kirameki effect) that occurs when real light hits an object
Solution Approach 1:
The patent segments the image processing into multiple independent modules: angular profile data generation from multi-camera images, noise filtering, image compensation, and discontinuity reduction. Each module handles a specific aspect of the transformation from ordinary images to glossy-effect display data, allowing the system to achieve both HDR contrast and realistic glossy effects through coordinated processing of multiple image components
Solution Approach 2:
The patent introduces angular profile data as an intermediary representation that bridges the gap between standard HDR images and realistic glossy effects. This intermediate data structure captures light reflection characteristics at different angles, enabling the display to reconstruct realistic glossy effects while maintaining HDR brightness contrast through controlled light distribution
2Reliability
If the display presents a glossy and realistic effect, then visual realism is improved, but the light profile of the image needs further processing or optimization to provide satisfactory visual effects
Solution Approach 1:
The patent performs preliminary processing to generate angular profile data from multiple camera images before the actual display rendering. By pre-computing the light reflection characteristics and storing them in an optimized angular profile format, the system reduces the processing complexity during real-time display while maintaining realistic glossy effects through the pre-prepared optical data
3Manufacturing precision
If multiple processing steps (noise filtering, image compensation, discontinuity reduction) are applied to image data, then image quality is improved, but processing time and computational resources increase
Solution Approach 1:
The patent transforms the image data from standard RGB format to angular profile data format, fundamentally changing the parameter representation. This parameter transformation allows the system to encode multiple processing results (noise filtering, compensation, discontinuity reduction) into a unified angular representation, reducing the need for separate processing steps and decreasing overall processing time while maintaining high image quality
