Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mobile camera technology forces users to choose between lower quality selfies using the front view camera or physically reorienting the device to use the higher quality world view camera, leading to awkward or dangerous positioning to include backgrounds in photos.

Innovation Solution

Simultaneously activating both front view and world view cameras to capture and overlay foreground and background image data, allowing real-time preview and manipulation of the composite image, enabling users to take high-quality selfies without repositioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the front view camera is used for selfies, then the user can capture self portraits with background images, but the image quality is lower

Engineering Contradiction:

Improveselfie capture convenienceVSAvoidimage quality

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent merges images from two separate cameras (front view camera and world view camera) into a single composite image. The front view camera captures the user's face while the world view camera captures the background, and these are combined to produce a high-quality selfie with background, resolving the contradiction between ease of operation and image quality.

Inventive Principle:

Principle #5Merging (Combining)

2Measurement precision

If the world view camera is used for selfies, then the image quality is higher, but the user must physically reorient the device which is awkward or dangerous

Engineering Contradiction:

Improveimage qualityVSAvoiddevice positioning

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system combines data from two cameras positioned at different orientations on the device. The world view camera (positioned for high-quality background capture) and front view camera (positioned for user-facing capture) are merged through image processing, allowing high-quality selfies without requiring the user to physically reorient the device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary processing system that receives images from both cameras and combines them. This intermediary image processing layer mediates between the two camera inputs, aligning and merging the images to create a final high-quality selfie image without requiring physical device repositioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If the world view camera is used for selfies, then high quality images can be captured, but users cannot include background images without repositioning

Engineering Contradiction:

Improveimage qualityVSAvoidbackground inclusion capability

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)
