Mobile Cradle Subject Tracking for Stable Multi-Angle Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices face limitations in capturing images of moving subjects and capturing images at different angles without user intervention, as they either suffer from shaking when handheld or are restricted to specific angles when fixed on a tripod.
Innovation Solution
A mobile device cradle system controlled by a mobile device with a processor that detects subjects and adjusts its orientation to track moving subjects, allowing for automatic image capture at various angles and combining images taken from different directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person directly holds the camera to capture an image, then the person can freely change the image capturing direction, but shaking occurs and limits image quality
Solution Approach 1:
The patent introduces a cradle as an intermediary device between the user and the camera. The cradle includes a rotating mechanism with a motor that automatically adjusts the camera's orientation based on subject position detection, eliminating the need for manual holding while maintaining operational flexibility.
Solution Approach 2:
The system enables self-service operation by automatically detecting the subject's position in the captured image and autonomously adjusting the camera angle through the rotating mechanism, without requiring manual intervention for directional changes.
2Reliability
If a fixing device such as a tripod is used to capture an image, then shaking is reduced, but the image can be captured only at a specific angle
Solution Approach 1:
The patent transforms the static tripod into a dynamic system by incorporating a rotating mechanism driven by a motor. This allows the camera to maintain stability while dynamically adjusting its capturing angle based on real-time subject position detection, combining the benefits of both fixed and flexible approaches.
Solution Approach 2:
The system implements feedback control by detecting the subject's position in the captured image and using this information to automatically adjust the camera's orientation through the rotating mechanism, enabling the camera to track and follow the subject while maintaining stability.
3Adaptability or versatility
If manual adjustment of camera angle is performed to follow a moving subject, then the subject can be tracked, but user intervention is required continuously
Solution Approach 1:
The system achieves self-service operation by automatically detecting the subject's position in each captured image and autonomously controlling the rotating mechanism to reorient the camera toward the subject, eliminating the need for continuous manual intervention while maintaining effective subject tracking.
4Productivity
If multiple images are captured at different angles to capture a moving subject, then comprehensive coverage is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The patent employs a dynamic rotating mechanism that automatically adjusts the camera angle based on real-time subject position detection, enabling continuous tracking and comprehensive coverage without requiring manual switching between multiple fixed-angle positions, thereby simplifying the process and improving efficiency.

AI summary
A mobile device which operates in conjunction with a mobile device cradle is provided. The mobile device is a mobile device which is held by a mobile device cradle and controls the mobile device cradle to be driven, and may include at least one camera which captures a forward image, a display, and at least one processor which executes an application which detects a subject from the forward image and controls the mobile device cradle to be driven so that a forward direction of the mobile device follows the subject according to movement of the subject.
