Real-Time Color Correction via Overlay Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color correction tools face inefficiencies in performing multiple secondary corrections due to computational delays and lack of intuitive workflows, forcing users to repeatedly render entire images and lose context while making adjustments, with tools often scattered across multiple interfaces.
Innovation Solution
A user interface that overlays a correction interface directly on the digital image, allowing real-time responsiveness and intuitive adjustments through a 3D Look-up Table (LUT) for color correction, enabling users to select regions and apply corrections without leaving the image view, with refinement tools like editable curves and 3D histograms for precision.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional color correction tools are used to perform multiple secondary corrections, then color adjustment capability is provided, but computational delays occur and users must repeatedly render entire images
Solution Approach 1:
The patent segments the image processing into multiple passes, performing rough color corrections first and then refining specific regions in subsequent passes. This allows the system to handle multiple secondary corrections efficiently by breaking down the computational task into manageable segments rather than processing the entire image at full resolution for each adjustment.
Solution Approach 2:
The patent applies color corrections at multiple levels of image detail, using lower-resolution versions for initial adjustments and applying final refinements only to selected regions at full resolution. This partial action approach reduces overall computational delay while maintaining the versatility to perform multiple secondary corrections where needed.
2Adaptability or versatility
If the correction interface is separate from the image display window, then tool functionality is provided, but users lose context and must repeatedly take their eyes off the image
Solution Approach 1:
The patent merges the correction interface with the image display window by overlaying correction tools and controls directly on top of the image. This integration allows users to access full correction functionality while continuously viewing the image, eliminating the need to switch between separate windows and maintaining workflow continuity.
Solution Approach 2:
The patent adds a new dimension to the interface by layering correction controls in the Z-dimension (overlay) rather than requiring users to switch to a separate window. This dimensional approach maintains ease of operation by keeping all tools accessible within the same visual space while preserving full correction capabilities.
3Productivity
If default or preset ranges are used for color correction parameters, then quick adjustments are possible, but the ranges are not sufficient for specific tasks requiring precision
Solution Approach 1:
The patent implements dynamic parameter ranges that automatically adjust based on the selected region and correction type. Instead of static default ranges, the system dynamically determines appropriate ranges for luminance, hue, and saturation parameters based on the specific image content and selected area, providing both quick adjustments and task-specific precision.
Solution Approach 2:
The patent allows users to modify correction parameter ranges interactively while providing intelligent defaults. The system dynamically changes parameter ranges based on user selections and image characteristics, enabling quick start with preset ranges while allowing precise customization when needed for specific correction tasks.

AI summary
The disclosed implementations relate generally to improved workflows for color correcting digital images. In some implementations, a method of correcting images includes: presenting a user interface on a display device, the user interface including a display area; presenting a digital image in the display area; overlaying a correction interface on the digital image; and performing a correction operation on at least a portion of the digital image in response to a user interaction with the correction interface, where the correction operation is performed with real-time responsiveness.
