Solution Overview

Problem

Existing graphics manipulation applications are inefficient and non-intuitive for digitally implementing overpainting operations, requiring multiple brushstrokes to achieve desired opacity and color changes, obscuring the original target area and lacking in precision.

Innovation Solution

A graphics manipulation application that uses tunable brushstroke parameters, including a maximum alpha-deposition parameter and a fractional alpha-deposition parameter, to control opacity and color changes, allowing for incremental adjustments based on current canvas opacity, thereby simplifying the overpainting process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing graphics manipulation applications use traditional opacity and flow parameters for digital brushstrokes, then users can control the extent of canvas color visibility and brush color application, but users must apply multiple sets of brushstrokes to achieve overpainting effects, which is inefficient and obscures the original target area

Engineering Contradiction:

Improveease of overpainting operationVSAvoidtime required for overpainting operation

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent combines opacity modification and color replacement into a single integrated overpainting operation. Instead of requiring separate brushstrokes for opacity adjustment and color application, the system merges these functions into one operation that simultaneously achieves both effects, thereby improving ease of operation and reducing time consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The overpainting tool is designed to perform multiple functions in a single operation: it replaces color information, modifies opacity, and preserves the original target area visibility. This multi-functional approach eliminates the need for multiple specialized tools and operations, making the process more efficient and user-friendly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If existing graphics manipulation applications apply opaque color to replace canvas portion, then the new color is fully applied, but the original canvas color and opacity cannot be preserved or adjusted intuitively

Engineering Contradiction:

Improveprecision of color replacementVSAvoidloss of original canvas opacity information

Core Design Contradiction:

Manufacturing precisionVSLoss of information

Solution Approach 1:

The system performs preliminary analysis of the original canvas portion's color and opacity characteristics before applying the overpainting operation. This preliminary action allows the system to preserve and reference the original properties, enabling precise control over the replacement process and preventing irreversible loss of information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The overpainting operation incorporates feedback mechanisms that continuously monitor the original canvas properties during the painting process. This feedback allows the system to adjust the replacement operation in real-time, ensuring that the original opacity and color information are preserved to the desired extent while achieving the new color effect.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If existing graphics manipulation applications use multiple brushstroke operations for overpainting, then color replacement is achieved, but the process is complex and requires switching between different tools

Engineering Contradiction:

Improveversatility of painting toolVSAvoidcomplexity of overpainting process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The painting tool is enhanced with universal overpainting capabilities that allow it to perform color replacement, opacity adjustment, and original area preservation all in one operation. This eliminates the need for multiple specialized tools and simplifies the overall process, reducing device complexity while maintaining versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges multiple discrete painting operations (color application, opacity control, area selection) into a single integrated overpainting tool. This consolidation reduces the complexity of the painting process by eliminating the need to switch between different tools and operations, while maintaining the adaptability needed for various painting scenarios.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Certain embodiments involve a graphics manipulation application using brushstroke parameters that include a maximum alpha-deposition parameter and a fractional alpha-deposition parameter. For instance, the graphics manipulation application uses an alpha flow increment computed from the maximum alpha-deposition parameter and the fractional alpha-deposition parameter to compute an output canvas color. In some embodiments, if the current canvas opacity exceeds or equals the maximum alpha-deposition parameter, the current canvas opacity is selected as the output canvas opacity. Otherwise, the graphics manipulation application computes the output canvas opacity by increasing the current canvas opacity based on the alpha flow increment. The graphics manipulation application updates a canvas portion affected by a brushstroke input to include the output canvas opacity and the output canvas color.
