Solution Overview

Problem

Multi-camera and multi-microphone systems often produce inconsistent visual and audio characteristics due to differences in camera and microphone brands/types, leading to noticeable and distracting changes when switching between them, which is particularly challenging for smaller scale content creators using off-the-shelf equipment.

Innovation Solution

Implementing style transfer functions, such as neural network-based algorithms, to calibrate and normalize the visual and audio characteristics of multiple cameras and microphones to match a reference sensor, ensuring consistent output across switches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras and microphones of different brands/types are used, then equipment versatility and cost-effectiveness are improved, but visual and audio characteristic consistency deteriorates

Engineering Contradiction:
Improveequipment versatilityVSAvoidvisual and audio characteristic consistency
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system adjusts camera parameters (exposure, white balance, color temperature, saturation, contrast, sharpness) and audio parameters (gain, noise floor, frequency response, reverberation) to transform the characteristics of each sensor to match the reference sensor, resolving the contradiction between using diverse equipment and maintaining consistent output

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If style transfer functions are applied to all video feeds, then visual characteristic consistency is improved, but computational load increases

Engineering Contradiction:
Improvevisual characteristic consistencyVSAvoidcomputational load
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The system performs style transfer calibration during an initialization phase before live streaming begins, pre-adjusting the video filter parameter settings based on style transfer analysis. During actual streaming, only lightweight real-time filtering is applied using the pre-determined parameters, significantly reducing ongoing computational load while maintaining consistency

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If real-time calibration is performed during live streaming, then visual and audio consistency is improved, but processing time and system complexity increase

Engineering Contradiction:
Improvevisual and audio consistencyVSAvoidprocessing time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The system performs comprehensive style transfer calibration and determines optimal filter parameter settings during initialization before live streaming begins. This preliminary action ensures that when switching between cameras or microphones during streaming, the pre-calibrated parameters enable immediate consistent output without requiring time-consuming real-time recalibration

Inventive Principle:
Principle #10Preliminary action

AI summary

Systems and methods for applying style transfer functions in multi-camera systems and multi-microphone systems are disclosed herein. An example multi-camera style transfer system includes at least one memory, instructions in the system, and processor circuitry to execute the instructions to at least apply a style transfer function to a second image from a second video feed to generate a stylized image based on a reference image. The reference image corresponds to a first image from a first video feed. The first video feed is from a first camera. The second video feed is from a second camera. The processor circuitry also executed the instructions to adjust one or more parameter settings of a video filter based on the stylized image, and filter the second video feed using the video filter with the adjusted parameter settings to generate a filtered version of the second video feed.
