Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Visual media recording devices with multiple cameras can only record a single visual medium at a time, limiting users to choose between capturing what they are viewing or their reaction, but not both simultaneously.

Innovation Solution

Systems and methods for simultaneously recording multiple visual media using a plurality of cameras, combining the recorded media post-capture into a single visual output, and displaying it on social media platforms or during real-time video communications, with optional enhancements like face-tracking and overlay applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a visual media recording device with multiple cameras records only a single visual medium at a time, then the device complexity is reduced and ease of operation is improved, but the adaptability and versatility are limited as users cannot capture both the scene and their reaction simultaneously

Engineering Contradiction:

Improvecapability to capture multiple perspectives simultaneouslyVSAvoidcomplexity of simultaneous multi-camera recording system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the recording function into separate camera modules (front-facing camera for reactions, rear-facing camera for scene) that operate independently but are coordinated by a control system. This segmentation allows each camera to be optimized for its specific function while the system as a whole achieves multi-perspective capture capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The visual media recording device is designed to perform multiple functions: capturing the scene, capturing reactions, and combining both perspectives into a unified output. The system can switch between different recording modes (single camera, multiple cameras simultaneously) to adapt to different user needs, achieving multi-functionality without requiring separate dedicated devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple cameras are used to record different perspectives simultaneously, then the adaptability and versatility are improved, but the device complexity and processing requirements increase

Engineering Contradiction:

Improveability to record both scene and reactionVSAvoidcomplexity of post-capture combining process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a control system and post-capture processing module as intermediaries that manage the complexity of coordinating multiple cameras and combining their outputs. These intermediary components handle the synchronization, alignment, and integration of footage from different cameras, shielding the user from the underlying complexity while enabling multi-perspective recording.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by pre-processing the footage from multiple cameras during the recording phase, including synchronization and initial alignment. This preliminary processing reduces the complexity of the final combining operation and ensures that the integration of multiple perspectives is seamless when the recording is complete.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If face-tracking technology is implemented in the cameras, then the ease of operation is improved and user engagement is enhanced, but the use of energy and processing power increases

Engineering Contradiction:

Improveautomation of subject trackingVSAvoidenergy consumption of face-tracking processing

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The face-tracking technology is applied selectively rather than continuously across all cameras and all recording modes. The system activates face-tracking only when needed (e.g., when capturing reactions with the front-facing camera) and adjusts the intensity of tracking based on the recording context, reducing unnecessary energy consumption while maintaining ease of operation when the feature is utilized.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Methods, systems, and storage media for simultaneously recording multiple visual media using a plurality of cameras of a visual media recording device are disclosed. Exemplary implementations may: record a first visual medium using a first camera (e.g., a front-facing camera) of the plurality of cameras of the visual media recording device; record a second visual medium using a second camera (e.g., a rear-facing camera) of the plurality of cameras of the visual media recording device simultaneously with recording of the first visual medium, at least one of the first camera and the second camera utilizing face-tracking technology during recording; combine the first visual medium and the second visual medium into a single visual output during a post-recording process; and cause display of the single visual output.
