Dual Lens Handheld Device Simultaneous Portrait Landscape Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electrical devices struggle to capture images in both portrait and landscape modes without distortion, as existing systems require image reduction or cutting, which affects video quality and user satisfaction.
Innovation Solution
A handheld electrical device with dual lens modules, each capturing images with different boundaries, allowing simultaneous capture of portrait and landscape images without moving the device, and a control unit to manage these captures, along with an input unit for user input and an orientation sensing module for real-time display adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single lens module captures images in landscape mode, then the image capturing boundary is optimized for landscape orientation, but portrait images require reduction or cutting which degrades image quality
Solution Approach 1:
The patent divides the imaging function into two separate lens modules: a first lens module optimized for landscape orientation and a second lens module optimized for portrait orientation. Each module has its own image capturing boundary tailored to its orientation, eliminating the need to reduce or cut images when switching between portrait and landscape modes, thus preserving image quality while providing orientation versatility.
2Adaptability or versatility
If portrait images are reduced or cut to fit landscape boundaries, then orientation compatibility is achieved, but image distortion increases especially in video
Solution Approach 1:
By segmenting the imaging system into orientation-specific lens modules, the patent allows each module to capture images in its optimal orientation without distortion. The first lens module captures landscape images with proper aspect ratio, while the second lens module captures portrait images with proper aspect ratio, eliminating the need for reduction or cutting that causes distortion.
Solution Approach 2:
Instead of forcing portrait images to fit landscape boundaries (the conventional approach), the patent inverts the approach by providing dedicated capture boundaries for each orientation. This inversion allows portrait images to be captured natively in portrait mode with their own optimized boundary, preventing distortion while maintaining orientation compatibility.
3Adaptability or versatility
If the handheld device moves to capture different orientations, then multiple boundaries can be captured, but the risk of missing fleeting moments increases
Solution Approach 1:
The patent segments the capture function into two simultaneously operating lens modules with different image capturing boundaries. This allows the device to capture both landscape and portrait orientations at the same time without moving, ensuring that fleeting moments are not missed while still providing comprehensive boundary coverage for different orientations.
Solution Approach 2:
The patent prepares for different orientation needs in advance by having both lens modules ready and active simultaneously. Rather than moving the device to capture different orientations after the fact, the system has both landscape and portrait capture capabilities prepared and operating concurrently, ensuring reliable capture of unexpected moments in either orientation.

AI summary
A handheld electronic device includes a first lens module, a second lens module, an input unit and a control unit. The first lens module and the second lens module are respectively disposed on the handheld electronic device. The first lens module captures scenes in a first image capturing boundary. The second lens module captures scenes in a second image capturing boundary, which is different from the first image capturing boundary. The input unit is used for receiving a user input for capturing images. When the input unit receives the user input, the control unit controls the first lens module and the second lens module to captures a first image and a second image respectively at the same time.
