Selective Night Mode Color Processing for Display Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing device displays that apply a night mode color process to entire frames, regardless of content, distort colors in images and videos, rendering certain features imperceptible and reducing image quality.
Innovation Solution
A method for selectively applying a night mode color process to computing device displays by identifying a region of interest and a remainder region, applying the night mode process only to the remainder region and maintaining normal colors for the region of interest, using a composer module and potentially aided by machine learning models or user input.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a night mode color process is applied to the entire frame, then eye strain is reduced, but image color quality is distorted and features become imperceptible
Solution Approach 1:
The display frame is divided into two distinct regions: a region of interest where normal color processing is applied to preserve image quality, and a remainder region where night mode color processing is applied to reduce eye strain. This spatial segmentation allows both contradictory requirements to be satisfied in different parts of the same display output.
Solution Approach 2:
Different color processing qualities are applied to different spatial locations within the frame. The region of interest maintains normal color characteristics for accurate image representation, while the remainder region applies warm/amber color characteristics for eye strain reduction. This local differentiation resolves the contradiction between global eye strain reduction and local image quality preservation.
2Illumination intensity
If a night mode color process is applied to the entire frame, then warmer light is emitted, but image features become imperceptible
Solution Approach 1:
The frame is segmented into regions requiring different illumination characteristics. The region of interest preserves normal light characteristics to maintain perceptibility of image features, while the remainder region emits warmer light to reduce eye strain. This segmentation prevents information loss in critical areas while achieving the illumination benefits in non-critical areas.
Solution Approach 2:
Different illumination qualities are applied locally across the display frame. Critical image regions maintain normal illumination for feature perceptibility, while non-critical regions provide warmer illumination for comfort. This local quality differentiation resolves the contradiction between global warmth and local information preservation.
3Manufacturing precision
If selective color processing is applied to different regions, then image quality is preserved, but device complexity increases
Solution Approach 1:
The night mode color processing function is extracted and applied selectively only to the remainder region, while the region of interest undergoes normal color processing. This extraction approach simplifies the overall system by avoiding the need for completely independent processing pipelines for each region, reducing device complexity while maintaining image quality.
