Video Bias Lighting Effect Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The discrepancy between the aspect ratio of mobile device displays and videos, along with screen orientation, leads to high contrast regions between video edges and the rest of the graphical user interface, causing eye strain and fatigue for viewers.
Innovation Solution
A computer-implemented method and system that samples the edge portions of video frames, inverts, blurs, and applies visual modifications such as stretching, enlarging, or adjusting opacity to generate a bias lighting effect, which is then displayed adjacent to the video frame to reduce contrast and enhance immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If solid blocks of color are used to fill unused display areas, then the display screen fully utilizes available space, but high contrast regions are created between video edges and the interface causing eye strain
Solution Approach 1:
Instead of filling the unused display areas with solid colors that create harsh contrasts, the patent inverts the approach by using the video content itself to create the filling effect. The edge portions of the video are sampled, inverted, and applied as bias lighting effects in the unused areas, thereby using the video's own visual information to eliminate the harmful contrast rather than introducing new solid color elements.
Solution Approach 2:
The patent applies color changes by transforming the edge portions of the video frames through inversion and visual modifications to create bias lighting effects. These modified color regions are then displayed in the unused areas of the display screen, creating a gradual transition that eliminates harsh contrasts while maintaining full display space utilization.
2Device complexity
If solid blocks of color are used to fill unused display areas, then the display layout is simple, but the visual experience becomes less immersive due to harsh contrast
Solution Approach 1:
The patent applies local quality by treating different regions of the display screen differently. The central area displays the video content while the unused peripheral areas receive bias lighting effects generated from the video's own edge portions. This localized application of visual modifications creates a more immersive experience without requiring complete redesign of the entire display layout.
Solution Approach 2:
The video content itself serves the dual purpose of being displayed centrally and of providing the visual elements for the bias lighting effects in unused areas. The edge portions of the video frames are sampled and reused to create the surrounding lighting effects, making the video content self-sufficient and eliminating the need for separate background elements.
3Adaptability or versatility
If the video occupies only a portion of the display screen, then the aspect ratio discrepancy is addressed, but contrast between video edges and interface increases causing fatigue
Solution Approach 1:
The patent applies preliminary action by pre-processing the video frames to extract and invert edge portions before displaying them in the unused areas. This preliminary extraction and transformation of visual elements allows the system to proactively create smooth transitions and eliminate harsh contrasts before the viewer perceives them, thereby preventing fatigue.
Solution Approach 2:
The bias lighting effects serve as an intermediary element between the video content and the display screen background. By inserting these modified edge portions as intermediate visual elements in the unused areas, the patent creates a gradual visual transition that mediates the contrast between the video edges and the surrounding interface, reducing viewer fatigue.

AI summary
Systems and methods for generating a bias lighting effect are provided. A computer-implemented method can include obtaining a video comprising a plurality of video frames. For each of one or more video frames of the plurality of video frames, the method can include sampling an edge portion of the video frame. The edge portion can include a portion of the video frame adjacent to an edge of the video frame. The method can further include generating a bias lighting effect for the video frame. Generating the bias lighting effect can include inverting the edge portion across the edge and blurring the edge portion. The method can further include displaying the video frame concurrently with the bias lighting effect for the video frame. The bias lighting effect can be displayed adjacent to the edge of the video frame.
