Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content creation and presentation technologies struggle to effectively composite and render content with varying dynamic ranges and color gamuts, leading to suboptimal display quality on different devices and environments.
Innovation Solution
A method and system for generating metadata that includes spatial and image metadata, allowing for the compositing and rendering of content in a way that adjusts the appearance of individual elements and their spatial proximity, optimizing display quality across various devices and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If content is composited from multiple elements with different dynamic ranges and color gamuts, then display quality can be optimized for specific devices, but the complexity of metadata generation and processing increases
Solution Approach 1:
The patent segments the compositing process by generating metadata for each individual content element separately, capturing its specific dynamic range and color gamut characteristics. This segmentation allows each element to be processed independently with appropriate metadata, which is then combined during rendering to achieve overall display optimization without requiring complex global processing.
Solution Approach 2:
The patent applies preliminary action by generating metadata for each content element in advance during the compositing process. This metadata captures essential characteristics (dynamic range, color gamut) before rendering, allowing the rendering system to efficiently process pre-prepared elements with their associated metadata rather than computing these characteristics during real-time rendering.
2Measurement precision
If metadata is generated for each individual content element, then perceptual accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The patent applies local quality by generating metadata that is specific to each content element's local characteristics (dynamic range, color gamut, spatial position). This element-specific metadata approach provides high perceptual accuracy for each individual element while avoiding the need to process the entire composited image with uniform metadata, thereby reducing overall processing time.
3Object-affected harmful factors
If content elements are adjusted based on spatial proximity and metadata, then visual comfort is improved by reducing glare, but the rendering complexity increases
Solution Approach 1:
The patent uses spatial metadata as an intermediary that captures the spatial relationships and positional information between content elements. This intermediary metadata enables the rendering system to automatically adjust elements based on their spatial proximity and potential glare interactions without requiring complex real-time calculations, thereby reducing visual discomfort while maintaining rendering efficiency.

AI summary
Approaches for generating metadata for content to be composited and rendered are described. These approaches can be used with the development and distribution of one or more web pages or other graphical user interfaces. For example, a web page developer can collect content to be composited together into a web page and invoke a set of APIs to generate the metadata for the content of the web page that will be composited; a metadata generation system receives the calls through the API and generates the metadata. The web page can then be distributed with the generated metadata which can be used to create the display of the web page with content that is perceptually modified based on the metadata about the individual elements on the web page and their spatial proximity.
