Stereo Camera Gesture Detection via Secondary Sensor Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for capturing stereoscopic images require two cameras, which increase costs and weight, and users often fail to maintain the correct gesture for capturing images, leading to imprecise disparity information and poor depth computation.
Innovation Solution
A controlling method for an electronic apparatus with two image-capturing units, where the second unit captures additional images to detect the relative displacement of objects and determine if the first images were captured with an appropriate or inappropriate gesture, prompting the user to adjust their movement accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two cameras are used to capture stereoscopic images, then depth information can be obtained, but the cost and weight increase
Solution Approach 1:
The system divides the image capture function into two separate units: a first image-capturing unit for capturing main images and a second image-capturing unit for capturing auxiliary images used for gesture detection. This segmentation allows the system to use a single lightweight camera for stereo imaging while adding a separate, smaller sensor for gesture monitoring, thereby reducing overall weight while maintaining depth information capability.
Solution Approach 2:
The patent introduces a gesture detection mechanism as an intermediary component that uses a second image-capturing unit to monitor and detect user gestures. This intermediary system provides feedback about capture quality without requiring a second full-function camera for stereo imaging, thus reducing weight while preserving depth information acquisition capability.
2Ease of operation
If users manually hold the camera, then operation is simple, but the gesture may be inappropriate leading to imprecise disparity information
Solution Approach 1:
The system implements a feedback mechanism where the second image-capturing unit continuously monitors user gestures during image capture. The control module analyzes the captured images to detect gesture patterns and provides real-time feedback about whether the capture gesture is appropriate. This feedback loop guides users to maintain correct gestures without complicating the manual operation process.
Solution Approach 2:
The patent replaces the need for mechanical precision in manual holding with an optical detection system. Instead of relying on users to physically maintain precise camera positioning and orientation, the system uses the second image-capturing unit to optically detect gestures and the control module to analyze image data, substituting mechanical precision requirements with computational analysis.
3Measurement precision
If a second camera is added for gesture detection, then gesture accuracy can be monitored, but device complexity increases
Solution Approach 1:
The second image-capturing unit is designed with multi-functionality, serving both as a gesture detection sensor and as a contributor to the overall stereo imaging process. The control module integrates data from both image-capturing units, allowing the second unit to fulfill dual purposes: monitoring user gestures and providing additional depth information, thereby reducing the need for completely separate systems.
Solution Approach 2:
The patent merges the gesture detection function with the stereo imaging system by integrating the second image-capturing unit into the existing camera architecture. Both image-capturing units share common processing resources and control mechanisms, combining what could have been separate systems into a unified device that reduces overall complexity while maintaining gesture detection accuracy.

AI summary
A controlling method suitable for an electronic apparatus is disclosed herein. The electronic apparatus includes a first image-capturing unit and a second image-capturing unit. The controlling method includes steps of: obtaining a plurality of second images by the second image-capturing unit when the first image-capturing unit is operated to capture a plurality of first images for a stereo process; detecting an object in the second images; calculating a relative displacement of the object in the second images; and, determining whether the first images are captured by an inappropriate gesture according to the relative displacement calculated from the second images.
