Camera Module Sightline Switching Video Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with camera modules that can change their sightline face challenges in maintaining video recording quality when the sightline is rotated or changed, often resulting in unnecessary image recording and low-quality images due to changes in shoot conditions.
Innovation Solution
An electronic device with a camera module that adjusts image sensor rotation/flip settings and tuning parameters based on the changed sightline, pauses recording during sightline changes, and resumes recording only after ensuring optimal image quality is achieved, using a processor to control the camera module and driving module for seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera module changes its sightline during video recording, then the camera can capture different directions, but unnecessary images are recorded and image quality deteriorates
Solution Approach 1:
The system pauses video recording before the sightline change occurs and resumes recording after the change is complete. This preliminary action prevents capturing unnecessary images during the transition period when image quality would be poor, while still allowing the camera to change directions as needed.
Solution Approach 2:
The system monitors the sightline change state and uses this feedback to control the recording operation. When a sightline change is detected, the system automatically pauses recording; when the change is complete, it resumes recording. This feedback mechanism ensures that only high-quality images are recorded while still enabling directional changes.
2Adaptability or versatility
If the camera module changes its sightline during video recording, then the camera can capture different directions, but recording time is wasted
Solution Approach 1:
The system pauses recording only for the minimal time necessary to complete the sightline change, then immediately resumes. This preliminary pausing action prevents wasting time on low-quality frames during transition while minimizing the interruption to the overall recording process.
Solution Approach 2:
The system rushes through the sightline change transition by pausing recording during this brief period, then quickly resuming. This approach skips the time-consuming process of recording low-quality transitional frames while minimizing the overall interruption to the recording workflow.
3Manufacturing precision
If different shoot set values are applied to front and rear cameras, then each camera is optimized for its specific function, but camera switching is required when changing sightlines
Solution Approach 1:
The system makes a single camera module universal by enabling it to function in both front-facing and rear-facing modes through sightline changes. By applying different shoot set values dynamically based on the current sightline direction, the same hardware can be optimized for different shooting scenarios without requiring physical camera switching, thereby reducing device complexity.

AI summary
An electronic device including a camera module capable of changing a sightline and a method of recording video thereof are provided. The electronic device includes a display, a camera module capable of changing a sightline, a driving module configured to control changing of a sightline of the camera module, a processor connected to the display, the camera module, and the driving module, and a memory connected to the processor, and configured to store instructions. The instructions enable the processor to perform operations, the operations including obtaining a first image via the camera module, displaying a preview image of the obtained first image on the display, and recording the first image as video, pausing recording of the video, providing a sightline change effect image as a preview image, and controlling the driving module, adjusting the first set value to a second set value mapped to the second direction, obtaining a second image via the camera module, and providing the preview image, and recording the second image to be subsequent to the paused first image.
