Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video call systems face challenges when a user moves from their original location, as the image and audio capture and playback become disrupted, requiring an improved method to maintain a stable video call connection.
Innovation Solution
A video call apparatus and system that includes an image sensor, microphone, speaker, detector, and controller to adjust the configuration of these components based on the user's new location, ensuring continuous and optimal video and audio communication by adjusting the pan angle, tilt angle, zoom value, and directionality of the image sensor and microphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user moves from the original location to a new location, then the user can maintain flexibility in positioning, but the image and audio capture quality deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of image sensor and microphone configurations based on real-time detection of user location. The controller continuously monitors user position and automatically adjusts pan angles, tilt angles, zoom values, and directionality to maintain optimal capture quality regardless of user movement, transforming static capture devices into dynamically adaptive ones.
Solution Approach 2:
The system employs a detector to continuously monitor user location and feeds this information back to the controller, which then adjusts the image sensor and microphone configurations accordingly. This closed-loop feedback mechanism ensures that capture quality is maintained by constantly adapting to changes in user position.
2Reliability
If the image sensor and microphone configurations are adjusted to track user movement, then capture quality is maintained, but system complexity increases
Solution Approach 1:
The controller serves multiple functions: it detects user location, processes location data, determines optimal configuration parameters, and executes adjustments to image sensor and microphone settings. By consolidating these diverse functions into a single multi-functional controller, the system achieves the required capture quality without proportionally increasing overall system complexity.
Solution Approach 2:
The system performs self-adjustment through automated detection and configuration modification. The detector automatically identifies user location changes, and the controller autonomously adjusts the image sensor and microphone parameters without requiring manual intervention, thereby maintaining capture quality while minimizing the need for additional control interfaces or user actions.
3Reliability
If multiple components are adjusted simultaneously based on user location, then communication stability is improved, but control complexity increases
Solution Approach 1:
The control system segments the adjustment process into distinct functional modules: location detection, parameter calculation, and execution control. Each component (image sensor and microphone) has its own adjustment parameters (pan angle, tilt angle, zoom value, directionality) that are independently optimized based on user location, allowing complex multi-component coordination through modular, organized control logic.

AI summary
An apparatus, system and method for implementing a video call between a first caller and a second caller are provided. The apparatus includes: an image sensor which captures an image of the first caller; a display which displays an image of the second caller; a microphone which captures an audio input by the first caller; a speaker which outputs an audio input by the second caller; a detector which is configured to determine a location of the first caller; and a controller which controls the detector to determine the location of the first caller as corresponding to an original location, wherein in response to the first caller changing a location from the original location to a new location, the controller controls the detector to determine the location of the first caller as being the new location, and controls the microphone to adjust a configuration of the microphone based on the new location of the first caller.
