Solution Overview

Problem

Existing color adjustment systems lack intuitive user experiences and primarily focus on global control, failing to provide effective local control over image chromas.

Innovation Solution

A color adjustment system and method that utilizes a processor and display to present a control interface with distributed control points on a color plane, allowing users to move these points to redefine chromas, with calculations determining adjusted chromas based on distances to surrounding points, enabling local chroma adjustments and display of changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional color adjustment systems are used, then global color control is achieved, but local color control capability is lost

Engineering Contradiction:

Improvelocal color control capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the color adjustment system into multiple independent control points distributed across the image space. Each control point can independently adjust local chroma parameters, enabling localized color modification without affecting the entire image. This segmentation approach allows precise local control while maintaining system manageability through modular control units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different regions of the image to have different color adjustment properties. Each control point operates on its local region, enabling users to apply specific chroma adjustments to particular areas while leaving other regions unchanged. This creates spatially varying color control that adapts to local image characteristics.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If calculation-based color adjustment is used, then color modification is achieved, but intuitive user experience is lost

Engineering Contradiction:

Improveuser experience intuitivenessVSAvoidchroma adjustment precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent creates a virtual color control interface that mirrors the actual image structure. Control points are positioned and manipulated in a visual representation that directly corresponds to their effect on the underlying image data. This copying approach allows users to interact with intuitive visual elements while maintaining precise control over chroma adjustments through the mapped control interface.

Inventive Principle:

Principle #26Copying

AI summary

A color adjustment system includes a memory and a processor. The memory stores instructions. The processor is configured to access the instructions to perform the following: accessing an image; providing a control interface having control points distributed thereon, and the plurality of control points defines a plurality of areas on a color plane; in response to one of the control points being moved from a first location to a second location on the color plane, selecting adjusting areas adjacent to the first location, in order to redefine an original chroma in the adjusting areas to an adjusted chroma; and determining whether pixels of the image match the original chroma in the adjusting areas, and displaying the pixels with the adjusted chroma if the pixels are matched to the original chroma.
