Image Display With Upper-Body-Centered Aspect Ratio Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 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 image display apparatus includes a signal processing device that extracts a first area corresponding to the upper body in an image, adjusts the aspect ratio, and centers the display on this area, performing adjustments such as enlargement or blur processing to maintain the person-centered focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal processing such as edition is performed to match aspect ratios, then the image can be displayed on the display, but background areas are emphasized or outer areas are black-processed due to edition errors
Solution Approach 1:
The system performs preliminary detection of human bodies and determination of important areas (such as upper bodies) in the received image before aspect ratio adjustment. This allows the image processing to prioritize keeping these important areas within the display range, preventing them from being blacked out or misplaced during the aspect ratio conversion process.
Solution Approach 2:
The patent applies different processing priorities to different regions of the image. By identifying important areas (such as human bodies or upper bodies) and assigning them higher priority, the system ensures that these specific regions are preserved and properly positioned during aspect ratio adjustment, while other less important areas can be adjusted or blacked out as needed.
2Ease of operation
If the aspect ratio of the received image does not match the aspect ratio of the display, then edition processing is required, but this causes edition errors that emphasize background areas or black-process outer areas
Solution Approach 1:
The system uses feedback from body detection and important area determination to guide the aspect ratio adjustment process. By continuously monitoring the positions of detected bodies and adjusting the cropping or scaling parameters accordingly, the system ensures that important areas remain properly positioned and sized in the final displayed image, maintaining reliability across different aspect ratio scenarios.
3Adaptability or versatility
If edition processing is performed to adapt the image to the display aspect ratio, then the image can be displayed, but person-centered focus is lost due to edition errors
Solution Approach 1:
The system performs preliminary detection of human bodies and determination of important areas (such as upper bodies) in the received image before aspect ratio adjustment. This allows the image processing to prioritize keeping these important areas within the display range, preventing them from being blacked out or misplaced during the aspect ratio conversion process.
Solution Approach 2:
The patent applies different processing priorities to different regions of the image. By identifying important areas (such as human bodies or upper bodies) and assigning them higher priority, the system ensures that these specific regions are preserved and properly positioned during aspect ratio adjustment, while other less important areas can be adjusted or blacked out as needed.

AI summary
An image display apparatus is disclosed. According to an embodiment of the present disclosure, an image display apparatus comprises a display; and a signal processing device configured to receive a first image of a first aspect ratio, extract a first area including an upper body corresponding to a part of a body in the first image, and display a second image of a second aspect ratio centered on the first area on the display in an image display mode. Accordingly, a person-centered image may be displayed in the image display mode.
