Dual Camera Image Capture for Full-Screen Orientation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using a cell phone to record a scene, the inability to simultaneously capture and display images in both portrait and landscape modes affects the viewing experience, as vertically-oriented images are not fully displayed when the phone is held horizontally.
Innovation Solution
The implementation of a method and device that utilize two cameras positioned differently on a cell phone, allowing for simultaneous real-time capture and display of images in both portrait and landscape modes on separate display areas, enabling full-screen viewing regardless of the device's orientation.

Engineering Contradiction Analysis
1Adaptability or versatility
If a single camera is used to capture images, then the device structure is simple, but the image cannot be displayed in full screen when the phone orientation changes
Solution Approach 1:
The image collection system is segmented into multiple independent camera modules (first camera and second camera) positioned at different orientations. Each camera captures images in its specific orientation (portrait or landscape), and the display system segments the screen into corresponding display areas that can be independently controlled. This segmentation allows the system to adapt to different phone orientations without requiring a single complex camera that can capture both orientations simultaneously.
2Adaptability or versatility
If portrait mode recording is used, then vertical images are captured properly, but the images cannot be displayed in full screen when the phone is held horizontally
Solution Approach 1:
The display system dynamically adjusts which camera's images are shown and how they are displayed based on the phone's current orientation. When the phone is held vertically, the portrait-mode camera images are displayed in full screen. When the phone is rotated to horizontal position, the system automatically switches to displaying landscape-mode camera images or adjusts the display layout. This dynamic adaptation ensures full-screen display quality while maintaining ease of operation in different orientations.
3Adaptability or versatility
If multiple cameras are used to capture both portrait and landscape images simultaneously, then full-screen display in any orientation is achieved, but the device complexity increases
Solution Approach 1:
Multiple camera modules capturing in different orientations are merged into a unified image collection and processing system. The processor integrates images from both the first camera (portrait mode) and second camera (landscape mode), managing their synchronization and coordination. The display system merges the output from both cameras into a cohesive full-screen display that adapts to phone orientation. This merging approach achieves versatile display adaptability while managing complexity through integrated system architecture.

AI summary
A method includes, in response to a trigger instruction, obtaining first images from a first camera and displaying the first images on a first display area, and obtaining second images from a second camera and displaying the second images on a second display area. The first camera and the second camera are located at different positions. The first display area is different from the second display area.
