Dynamic Clipping Box Center Adjustment for Video Chat Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display apparatuses lack flexibility in adjusting the camera's shooting position, leading to suboptimal user experiences during video chats and other interactive applications, especially when users have varying heights, resulting in potential black edges and reduced display area.
Innovation Solution
A display apparatus with a camera and image processor that captures image data with a first aspect ratio, adjusts the center position of a clipping box to ensure the target object is centered, and outputs an adjusted image with a second aspect ratio, minimizing black edges and optimizing the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is arranged at the top of the display to enable image collection and video chat, then the display apparatus can provide video chat functionality, but the shooting position cannot be adjusted flexibly like a mobile phone
Solution Approach 1:
The patent implements dynamic adjustment of the clipping box center position based on detected target object positions. The image processor automatically shifts the clipping box center away from the geometric center of the display toward the target object, enabling the shooting position to adapt dynamically to different users and scenarios, thereby resolving the contradiction between fixed camera arrangement and flexible shooting position adjustment.
2Device complexity
If the display apparatus uses a fixed aspect ratio for image display, then the display structure is simple, but black edges appear and display area is reduced when users have varying heights
Solution Approach 1:
The patent changes the parameter of the clipping box center position from a fixed geometric center to a dynamically adjustable position. By modifying this parameter based on target object detection, the system optimizes the display area to eliminate black edges and accommodate users of varying heights, while maintaining the overall display structure's simplicity.
3Device complexity
If the clipping box center is fixed at the geometric center of the display, then the display structure is simple, but the target object is not always centered leading to poor user experience
Solution Approach 1:
The patent implements a feedback mechanism where the image processor continuously monitors the position of target objects and automatically adjusts the clipping box center position accordingly. This closed-loop control ensures the target object remains centered in the displayed image, significantly improving user experience without adding complex manual adjustment mechanisms.
Solution Approach 2:
The system performs self-service by automatically detecting target objects and adjusting the clipping box center position without requiring user intervention. The image processor autonomously centers the target object in the displayed image, eliminating the need for manual camera or display adjustments while maintaining system simplicity.
Data Source
AI summary
Disclosed is a display apparatus. When image data is received, a position of a clipping box is adjusted according to a position of a target object in the image data; and an adjusted image is output to a second chip, the adjusted image is a portion of the image data in the adjusted clipping box, and the second chip is configured to receive the adjusted image output from an image processor and output the adjusted image to a display.
