Pillarboxing Correction via Dynamic Fill Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in optimizing video content for different aspect ratios, leading to inefficient use of display space and image distortion when playing content formatted for one aspect ratio on a display with a different ratio, using methods like letterboxing and pillarboxing which result in blank regions and image quality loss.
Innovation Solution
A display control device is used to identify non-content regions in a display space and selectively fill them with data such as movie enhancing effects, video-related information, or user-provided data, enhancing the viewing experience by determining the appropriate fill data based on display and content properties.

1Area of stationary object
If pillarboxing correction is applied to display content with different aspect ratios, then the display space utilization is improved, but image distortion and quality loss occur
Solution Approach 1:
The patent applies different treatments to different regions of the display space. The non-content regions (pillars) are filled with enhanced data (movie effects, video information, user data) while the content region maintains its original aspect ratio. This local differentiation allows full display space utilization without distorting the content image quality.
Solution Approach 2:
The display space is segmented into content regions and non-content regions. The non-content regions are identified and filled separately from the content region, allowing independent optimization of each area. This segmentation enables full space utilization while preserving content integrity.
2Ease of operation
If pillarboxing correction fills non-content regions with data, then viewing experience is enhanced, but device complexity increases
Solution Approach 1:
The display control device automatically identifies non-content regions and determines appropriate fill data based on the content type and display properties. The system self-adjusts without requiring manual user input for each fill operation, reducing operational complexity while enhancing viewing experience.
Solution Approach 2:
The system dynamically adjusts fill data parameters (color, content type, positioning) based on evaluated display device information and content properties. This parameter adaptation allows complex enhancements to be achieved through algorithmic control rather than manual configuration.

AI summary
A display control device used to govern non-content regions in a display space, and selectively determine data for display in the non-content regions is described. The display control device can identify the non-content regions, and determine types of data that can be filled in the non-content regions. Once determined, the fill data can be presented in the non-content regions concurrently with an image frame.
