Person-Centered Image Display Through Upper-Body Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display apparatuses face issues when displaying images with mismatched aspect ratios, leading to emphasis on background areas or black-processing of outer regions due to edition errors when a person is included in the image.
Innovation Solution
The apparatus includes a signal processing device that extracts a first area corresponding to an upper body in the image and displays a second image centered on this area, adjusting the aspect ratio to ensure the person remains centered, even when multiple people are present or the area size is insufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal processing such as edition is performed when aspect ratios do not match, then the image can be displayed on the display, but background areas are emphasized or outer areas are black-processed due to edition error
Solution Approach 1:
The patent segments the image processing into distinct steps: detecting human bodies in the image, determining their positions and sizes, calculating the optimal centering point based on multiple body positions, and then performing aspect ratio adjustment. This segmentation allows precise control over which areas are preserved and how the centering is calculated, avoiding the black-processing and background emphasis problems of conventional edition methods.
Solution Approach 2:
The patent performs preliminary detection of human bodies and calculation of the optimal centering point before performing the aspect ratio adjustment. By pre-calculating the centering point based on body positions and sizes, the system ensures that the person remains centered in the displayed image, preventing the edition errors that would otherwise occur during the aspect ratio conversion process.
2Adaptability or versatility
If conventional edition is performed to match aspect ratios, then the image fits the display, but person-centered display is not maintained due to edition error
Solution Approach 1:
The patent uses feedback by continuously referencing the detected body positions and sizes during the aspect ratio adjustment process. The centering point is calculated based on the actual detected body information, and this calculated centering point guides the aspect ratio conversion to ensure the person remains centered. This feedback mechanism maintains measurement precision while achieving display format flexibility.
Solution Approach 2:
The patent changes the parameters used for aspect ratio adjustment from conventional center-based methods to body-detection-based parameters. By using the detected body positions, sizes, and calculated centering points as the basis for adjustment, the system maintains accurate person positioning while adapting to different display formats and aspect ratios.
3Manufacturing precision
If the first area including upper body is extracted and used for centering, then person-centered display is achieved, but device complexity increases due to body part extraction
Solution Approach 1:
The patent extracts the upper body area from the full image as the first area, using this extracted region as the basis for centering calculations. By taking out only the relevant upper body portion rather than processing the entire image, the system achieves accurate upper body centering while limiting the processing complexity to only the necessary regions.
Solution Approach 2:
The patent applies local quality by focusing processing on the upper body region rather than the entire image. The first area extraction isolates the relevant portion (upper body) for centering purposes, allowing precise local processing of the area that matters most while avoiding unnecessary complexity from processing the complete image.
