Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic range conversion technologies face limitations in transmitting and processing all required conversion information due to transmission rate and device capacity restrictions, leading to incomplete image conversion.
Innovation Solution
An encoding device that sets and prioritizes knee position information for dynamic range conversion, allowing selective transmission and use of essential conversion data, even under bandwidth and capacity constraints, by determining priority orders based on compression/extension rates and adding this information to encoded data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all knee position information is transmitted, then conversion accuracy is improved, but transmission bandwidth is exceeded
Solution Approach 1:
The patent extracts only the essential knee position information needed for dynamic range conversion, rather than transmitting all possible conversion data. By identifying and transmitting only the critical knee position parameters, the system achieves adequate conversion accuracy while staying within transmission bandwidth constraints.
Solution Approach 2:
The patent changes the parameter representation by using a simplified set of knee position information parameters instead of complete conversion data. This parameter reduction allows the system to maintain functional conversion accuracy while significantly reducing the quantity of transmitted information to fit within bandwidth limitations.
2Manufacturing precision
If all knee position information is processed, then conversion quality is improved, but device arithmetic capacity is exceeded
Solution Approach 1:
The patent extracts and processes only the essential knee position information parameters, avoiding the computational burden of processing all available conversion data. This selective extraction enables the device to achieve sufficient conversion quality without exceeding its arithmetic capacity limits.
Solution Approach 2:
The patent applies partial action by processing only the necessary portion of knee position information rather than all possible conversion parameters. This partial processing approach delivers adequate conversion quality while keeping computational requirements within the device's arithmetic capacity.
3Productivity
If priority ordering is implemented, then transmission efficiency is improved, but data structure complexity is increased
Solution Approach 1:
The patent applies preliminary action by pre-establishing a priority order for knee position information before transmission. This upfront organization of data according to importance allows the receiving device to efficiently process critical information first, improving transmission efficiency while maintaining a manageable data structure through systematic ordering.

AI summary
A conversion from a dynamic range conversion image into a desired image is performed in a favorable manner. A setting unit sets a plurality of items of knee position information about a conversion from a first dynamic range image into a second dynamic range image. An encoding unit encodes the second dynamic range image to generate encoded data. A determination unit determines priority order of the plurality of items of knee position information. An adding unit adds the plurality of items of knee position information to the encoded data of the second dynamic range image, with the priority order given to the plurality of items of knee position information.
