Mobile Camera Dynamic Shot Adjustment via Audio and Facial Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Amateur video producers lack the training and resources to improve the quality of their self-produced content, as they often operate cameras and are subjects simultaneously, necessitating a mechanism for dynamic camera adjustments without additional human assistance.
Innovation Solution
A method and system that utilize a mobile device's microphone to detect audio levels and facial expressions, dynamically adjusting camera parameters such as zoom, aperture, and lighting to enhance video production quality by emulating professional filmmaking techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single user operates the camera without assistance, then ease of operation is improved, but video production quality deteriorates
Solution Approach 1:
The camera system performs self-adjustment of shot parameters based on audio level analysis. The device automatically detects audio levels, determines shot adjustment states, and modifies camera parameters without requiring external operator intervention, enabling the camera to service itself during operation
Solution Approach 2:
The system continuously monitors audio levels from the recording environment and uses this feedback to dynamically adjust camera shots. The audio level information flows back to the control system, which then modifies zoom, aperture, or other parameters in response to detected sound variations, creating a closed-loop control system
2Manufacturing precision
If professional filmmaking techniques are used to improve video quality, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The mobile device performs multiple functions: it serves as the camera platform, audio recording device, audio analysis system, and shot control mechanism all in one. The same device that records audio also analyzes it and controls the camera based on that analysis, eliminating the need for separate professional equipment for each function
Solution Approach 2:
The patent replaces manual mechanical operation of camera parameters with an automated electronic control system. Instead of a human operator physically adjusting zoom rings or aperture settings, the system uses electronic signals derived from audio level analysis to automatically modify camera parameters through digital control

AI summary
An approach is provided for adjusting camera shots. The approach involves receiving an audio signal via a microphone of a mobile device during video recording of a subject by a camera of the mobile device. The approach also involves determining, at the mobile device, an audio level in a vicinity of the subject based on the received audio signal, wherein the audio level is based on sounds produced by the subject. The approach additionally involves determining that the audio level triggers a shot adjustment state. In the alternative or in addition to, the shot adjustment state is triggered by facial expression of the subject. The approach further involves dynamically adjusting, in response to the shot adjustment state, one or more camera parameters of the camera to alter shot of the subject by the camera during the video recording. The camera parameters relate to either zoom control, aperture, lighting, or a combination thereof.
