Camera Automatic Audio Transmitter Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AURACAST® broadcast audio systems face challenges in accurately selecting the correct sound transmission device for image capture, leading to potential mismatched sound data when shooting subjects due to cumbersome manual selection processes and interference from nearby transmitters.
Innovation Solution
An image capture apparatus with a detection unit for radio signals, an extraction unit for feature information from image data, a selection unit for automatically selecting the appropriate sound transmission device based on comparison information, and a reception unit for wireless communication to receive sound data from the selected device, ensuring accurate sound data corresponding to the shooting target is obtained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of transmitter is used, then user can choose desired transmitter, but selection operation is cumbersome and errors may occur
Solution Approach 1:
The camera performs automatic transmitter selection by itself using the assistant to scan available transmitters and automatically select the appropriate one based on shooting information, eliminating the need for manual user operation and reducing selection errors
Solution Approach 2:
The system uses feedback from the assistant's scan results and shooting information to automatically determine the appropriate transmitter, creating a closed-loop selection process that improves both ease of operation and reliability
2Reliability
If transmitters are arranged to avoid radio wave interference, then communication reliability improves, but sound data may be received from wrong transmitter when shooting subjects through glass or from distance
Solution Approach 1:
The assistant acts as an intermediary that scans and identifies available transmitters, providing information to the camera's control unit which then selects the appropriate transmitter based on shooting information, ensuring correct sound data reception even when multiple transmitters are present
Solution Approach 2:
The assistant performs preliminary scanning of transmitters before the actual shooting, and the control unit pre-selects the appropriate transmitter based on shooting information, ensuring the correct sound transmission device is identified before capturing images or videos
3Ease of operation
If automatic transmitter selection is implemented, then ease of operation improves, but device complexity increases due to assistant and selection logic
Solution Approach 1:
The assistant, originally designed for scanning and connection management, is extended to also perform transmitter identification and selection functions, allowing one component to serve multiple purposes and reducing overall system complexity despite added functionality

AI summary
An image capture apparatus comprises a detection unit that detects a radio signal, an extraction unit that extracts feature information of a subject from image data, a selection unit that selects a sound reception device that receives sound data from at least one sound transmission device from which the radio signal can be received, and a reception unit that receives, by a wireless communication unit, sound data from the selected sound transmission device selected by the selection unit. Based on a result of comparing feature information of a subject as a shooting target with comparison information for selecting the sound transmission device, the selection unit selects the sound transmission device that transmits sound data corresponding to the subject as the shooting target from at least one sound transmission device from which the radio signal can be received.
