Multiple-Intent Image Encoding with Appearance Adjustment Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image encoding and decoding technologies lose original image parameters and apply lossy operations, making it difficult to transmit and restore the original captured image while allowing for multiple rendering intents.
Innovation Solution
The method involves encoding an image with metadata that characterizes appearance and preference adjustments, allowing for the inversion of these adjustments during playback to restore the original captured image or create a pleasing image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If appearance adjustments are applied to the captured image during encoding, then the image is optimized for viewing and aesthetic appeal, but the original captured image parameters are lost and cannot be recovered
Solution Approach 1:
The patent applies appearance adjustments to the captured image during encoding while simultaneously recording the adjustment parameters in metadata. This preliminary action preserves the ability to invert adjustments later by storing the transformation information, thus preventing loss of original image parameters while still optimizing the image for viewing.
Solution Approach 2:
The patent implements a feedback mechanism where the adjustment parameters are captured and stored alongside the encoded image. This feedback loop allows the decoding device to understand what transformations were applied and to invert them accordingly, ensuring that original image parameters can be recovered when needed.
2Productivity
If lossy operations are applied during image encoding, then the image data is compressed for efficient transmission and storage, but the original image quality and parameters cannot be fully restored
Solution Approach 1:
The patent performs lossy compression on the image data while preliminarily storing the adjustment parameters in metadata format. This allows the compressed image to be efficiently transmitted and stored, while the preserved parameter information enables quality restoration through inversion of adjustments during decoding.
Solution Approach 2:
The patent introduces metadata as an intermediary element that carries the adjustment parameters separately from the compressed image data. This intermediary structure allows lossy compression to be applied to the image while maintaining the integrity of the transformation information, enabling quality restoration without compromising compression efficiency.
3Adaptability or versatility
If multiple rendering intents are supported, then the system provides flexibility in image presentation, but the complexity of encoding and decoding processes increases
Solution Approach 1:
The patent implements a universal metadata structure that can represent multiple types of appearance adjustments and rendering intents within a single framework. This multi-functional approach allows the same encoding and decoding process to handle various rendering scenarios without requiring separate complex pipelines for each intent.
Solution Approach 2:
The patent uses parameter-based control where different rendering intents are achieved by changing the values and combinations of adjustment parameters in the metadata. This approach allows multiple rendering intents to be supported through simple parameter variations rather than requiring fundamentally different processing approaches, thus managing complexity.
Data Source
AI summary
Systems and methods for encoding and decoding multiple-intent images and video using metadata. When encoding an image as a multiple-intent image, at least one appearance adjustment may be made to the image. Metadata characterizing the at least one appearance adjustment may be included in, or transmitted along with, the encoded multiple-intent image. When decoding a multiple-intent image, a system may obtain a selection of a desired rendering intent and, based on that selection, either render the multiple-intent image with the applied appearance adjustments or may use the metadata to invert the appearance adjustments and recover the image pre-appearance adjustments.
