Display Apparatus Aspect Ratio Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in presenting an intact image frame when the recording width-height ratio differs from the display device's screen width-height ratio, leading to incomplete frames and inefficient use of display space, particularly in cinema display systems where the 2.37:1 ratio is used, resulting in the need for black edges and inadequate subtitle region handling.
Innovation Solution
A display method and apparatus that divides the display frame into an image region and a subtitle region, adjusts their respective settings, and combines them to generate a final display frame, allowing for proportional scaling and effective presentation on cinema display systems by determining the subtitle region's position based on grayscale value distribution and adjusting transparency and display settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display frame is adjusted to match the screen width-height ratio (16:9), then the visual comfort and image realism are improved, but the original image frame cannot be entirely filled and black edges appear
Solution Approach 1:
The display frame is segmented into multiple regions including a first display region for the main image frame and a second display region for subtitles. This segmentation allows the image frame to be displayed at its original aspect ratio without distortion while dedicating a separate region for subtitles, thus preventing black edges from obscuring subtitle content.
Solution Approach 2:
Instead of adjusting the image frame to fit the screen width-height ratio (which would cause distortion or black edges), the patent places subtitles in a separate spatial dimension (second display region) below the main image frame. This dimensional separation allows both the original image aspect ratio and subtitle display to coexist without compromise.
2Area of stationary object
If black edges are added to fill the display frame, then the screen is fully utilized, but the subtitle region becomes inadequate and image quality deteriorates
Solution Approach 1:
The display frame is divided into distinct segments: a first display region for the image frame and a second display region for subtitles. This segmentation ensures that subtitles have a dedicated display area without being obscured by black edges, while the image frame maintains its original aspect ratio and quality.
Solution Approach 2:
The patent introduces a subtitle region as an intermediary element between the image frame and the black edges. This subtitle region serves as a mediator that utilizes the otherwise wasted space below the image frame, converting it from a harmful black edge into a useful subtitle display area.
3Measurement precision
If the image frame is scaled to maintain horizontal resolution, then the horizontal quality is preserved, but the vertical resolution becomes insufficient and black edges are required
Solution Approach 1:
The display frame is segmented into a first display region for the image frame and a second display region for subtitles. This allows the image frame to maintain its original vertical resolution and aspect ratio without being stretched or compressed, while the subtitle region occupies the additional vertical space that would otherwise be black edges.
4Adaptability or versatility
If subtitles are displayed in the black edge region, then subtitle display is enabled, but the image frame appears obscured and visual quality decreases
Solution Approach 1:
The display frame is clearly segmented into a first display region for the image frame and a second display region for subtitles. This spatial segmentation ensures that subtitles are displayed in a dedicated area below the image frame, preventing any obscuration of the image while maintaining full subtitle display capability.

AI summary
A display apparatus and associated method are provided. The display apparatus receives a display frame having an output width-height ratio, and outputs an image frame according to a screen width-height ratio. The output width-height ratio is different from the screen width-height ratio. The display method includes obtaining an image region and a subtitle region from the display frame, generating a subtitle according to the subtitle region, generating the image frame according to the image region, and displaying the image frame and the subtitle.
