Imaging Apparatus Subject Region Audio Target Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices lack the ability to easily identify and prioritize sound collection targets within a scene, leading to inefficient audio capture during image recording.
Innovation Solution
An imaging apparatus equipped with a display, image sensor, audio input device, detector, and controller that detects subject regions, distinguishes main subjects from secondary subjects, and controls sound collection areas and gains based on face recognition, allowing users to clearly capture intended audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging apparatus captures multiple subjects in a scene, then the audio capture coverage is improved, but it becomes difficult for users to identify which subject's sound is being collected
Solution Approach 1:
The patent applies visual identification markers (different display patterns such as frames, icons, or colors) to indicate different sound collection targets on the display screen. The controller displays first identification information for the main subject and second identification information for other subjects, enabling users to visually distinguish which subject's sound is being prioritized captured.
2Ease of operation
If the imaging apparatus automatically determines sound collection targets, then the ease of operation is improved, but the user's intent to capture specific subjects may not be accurately reflected
Solution Approach 1:
The system dynamically adjusts the sound collection configuration based on detected subject regions. The controller automatically determines main subjects and other subjects based on image analysis, and adjusts the sound collection area and gain accordingly. This dynamic adaptation allows the system to respond to changing scene conditions while maintaining accurate sound collection target identification.
3Measurement precision
If the imaging apparatus adjusts sound collection area and gain dynamically, then the audio quality for main subjects is improved, but the device complexity increases
Solution Approach 1:
The controller changes audio parameters (sound collection area and gain) based on the detected subject regions. When a main subject is identified, the system adjusts the sound collection area to focus on that region and modifies the gain to prioritize audio from that area. This parameter adjustment enables differentiated audio capture quality for main subjects versus other subjects in the scene.

AI summary
An imaging apparatus comprising: a display configured to display information; an image sensor configured to capture an image of a subject to generate image data; an audio input device configured to input audio to generate an audio signal indicating sound to be collected during image capturing with the image sensor; a detector configured to detect a subject region which corresponds to the subject in the image data; a controller configured to determine a main subject and a sound collection target for the audio signal, according to a subject region detected by the detector. When the detector detects a plurality of subject regions, the controller controls the display to display first identification information indicating a subject which is the main subject and is the sound collection target and second identification information indicating a subject which is different from the main subject and is the sound collection target distinguishably from each other.
