Camera Focusing via Locator Beacon Distance Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera focusing systems face challenges in maintaining accurate focus, especially when subjects are dynamic or multiple, leading to inefficiencies and increased production costs due to the need for manual adjustments and inability to reshoot scenes.
Innovation Solution
A system utilizing locator beacons and wireless communication to calculate and display focus distances, enabling continuous, automated focus control and transition between subjects, with both manual and servo-operated follow-focus capabilities, allowing a single operator to manage multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual focus adjustment is used, then the operator can control focus, but the process is time-consuming and inefficient for dynamic or multiple subjects
Solution Approach 1:
The patent replaces manual mechanical focus adjustment with an automated electronic system. A processor receives distance information from sensors (such as time-of-flight sensors or RFID tags) and automatically controls the lens focus mechanism, eliminating the need for manual operation and enabling real-time focus adjustment for dynamic subjects
Solution Approach 2:
The system enables self-service by allowing the camera to automatically determine subject distance and adjust focus without human intervention. The processor continuously monitors distance data from sensors and autonomously modifies lens positioning to maintain optimal focus, making the system self-regulating
2Productivity
If automated focus system is implemented, then focus adjustment speed improves, but system complexity increases
Solution Approach 1:
The processor serves multiple functions: it processes distance information from various sensor types (time-of-flight, RFID, ultrasonic), determines focus requirements, and controls the lens mechanism. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining automated focus capability
Solution Approach 2:
The patent introduces a processor as an intermediary that bridges the sensor system and the lens control mechanism. This central processing unit simplifies the overall system architecture by consolidating control logic and serving as a single point of coordination between distance measurement and focus execution
3Measurement precision
If distance measurement accuracy is improved, then focus precision increases, but measurement difficulty increases for dynamic subjects
Solution Approach 1:
The system performs preliminary distance measurement using sensors (such as time-of-flight sensors that emit and measure reflected light, or RFID tags that provide pre-encoded position data) before focus adjustment is needed. This advance measurement allows the processor to prepare focus settings in advance, improving both accuracy and response time for dynamic subjects
