Image Processing Apparatus Color Gloss Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to accurately reproduce the appearance of materials due to a mismatch between the object's appearance range and the reproduction range of the image reproduction apparatus, particularly in controlling gloss and color.
Innovation Solution
An image processing apparatus that performs color and gloss mapping to align the object's appearance data with the reproducible range of the apparatus, ensuring accurate reproduction by converting color and gloss information into ranges that the apparatus can handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color mapping is performed to map color information into a color reproducible range, then color reproduction accuracy is improved, but the gloss information may be lost or degraded
Solution Approach 1:
The appearance data processing is segmented into separate color mapping and gloss mapping operations. The color information is mapped to the color reproducible range while gloss information is independently mapped to the gloss reproducible range, allowing each to be optimized without compromising the other.
Solution Approach 2:
The system introduces an intermediate gloss mapping process that acts as a mediator between the original appearance data and the final reproduction. This intermediary step ensures that gloss information is properly transformed into the reproducible range while maintaining its integrity separate from color processing.
2Manufacturing precision
If gloss mapping is performed to map gloss information into a gloss reproducible range, then gloss reproduction accuracy is improved, but the color information may be lost or degraded
Solution Approach 1:
The processing is divided into independent color mapping and gloss mapping segments. Gloss information is mapped to the gloss reproducible range while color information is independently handled, preventing cross-contamination and information loss between the two distinct processing streams.
Solution Approach 2:
The system treats color and gloss as separate dimensions of appearance data. By mapping each dimension independently into its own reproducible range (color reproducible range and gloss reproducible range), the system avoids the information loss that would occur if both were compressed into a single processing channel.
3Productivity
If the appearance data is directly reproduced without mapping, then processing speed is maintained, but the reproduction accuracy deteriorates due to range mismatch
Solution Approach 1:
The system performs preliminary mapping of both color and gloss information into their respective reproducible ranges before the actual reproduction process. This advance preparation ensures that when reproduction occurs, the data is already in the correct format and range, maintaining processing speed while ensuring accuracy.
Solution Approach 2:
The system changes the parameters of the appearance data by mapping color values into the color reproducible range and gloss values into the gloss reproducible range. This parameter transformation allows the reproduction apparatus to accurately represent the original appearance while maintaining efficient processing through standardized mapping operations.

AI summary
Appearance data including at least color information and gloss information of an object to be reproduced is inputted. Color mapping is performed to map the color information into a color reproducible range of an appearance reproduction apparatus, based on information indicating an appearance reproducible range of the appearance reproduction apparatus. A gloss reproducible range, in which the appearance reproduction apparatus can reproduce gloss while keeping the color information after the color mapping, is obtained based on the information indicating the appearance reproducible range. Gloss mapping is performed to map the gloss information into the gloss reproducible range. An output signal to be outputted to the appearance reproduction apparatus is generated based on mapped appearance data including the color information after the color mapping and the gloss information after the gloss mapping.
