Solution Overview
Problem
Conventional panoramic camera devices have a large volume and limited application range due to their complex structure and limited field of view, which is not adequately addressed by traditional camera modules with narrow shooting angles.
Innovation Solution
A panoramic camera device with a simplified structure featuring two back-to-back camera modules positioned on the same optical axis, each with a lens unit, image processing unit, and filter, connected via ports for unified signal output, allowing for a wide-angle view and reduced module count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple shooting lenses are used to achieve panoramic shooting, then the field of view is improved, but the device volume increases
Solution Approach 1:
The panoramic camera device divides the imaging function into multiple independent camera modules (first camera module, second camera module, etc.) arranged along the optical axis. Each module captures images of a specific field of view, and the segments are combined to form a complete panoramic image, thereby achieving a wide field of view without requiring a single large-volume lens system.
Solution Approach 2:
Instead of expanding the field of view horizontally by using multiple lenses side-by-side, the patent arranges multiple camera modules along the optical axis (depth dimension). This dimensional change allows each module to capture a portion of the panoramic scene while maintaining a compact lateral footprint, thus reducing overall device volume while achieving the desired field of view.
2Adaptability or versatility
If multiple camera modules are used for panoramic imaging, then the field of view is improved, but the device complexity increases
Solution Approach 1:
Multiple camera modules are merged into a single integrated panoramic camera device with a unified structure. The modules share common components such as the optical axis, mounting substrate, and signal processing circuitry, which reduces overall complexity compared to using separate camera systems. The merged design allows for synchronized operation and simplified image stitching.
Solution Approach 2:
Each camera module is designed with universal functionality to capture images across different fields of view. The modules use identical or similar lens and sensor configurations, allowing them to perform multiple functions (capturing different portions of the panorama) with the same structural design, thereby reducing the complexity of designing and integrating diverse components.
3Measurement precision
If multiple image signals are output separately, then the image processing is accurate, but the signal transmission complexity increases
Solution Approach 1:
Multiple image signals from different camera modules are merged into a single composite signal for transmission. The panoramic camera device processes and combines the images from multiple modules internally, then outputs the final panoramic image through one signal line, reducing transmission complexity while maintaining image quality through integrated processing.
Solution Approach 2:
The patent introduces an intermediary processing unit that receives images from multiple camera modules, performs synchronization and stitching operations, and then outputs the final panoramic image. This intermediary layer simplifies the signal transmission interface by providing a single standardized output while handling the complexity of multi-signal integration internally.

AI summary
A panoramic camera device includes: a first substrate having a first surface and an opposite second surface, a first camera module being disposed on the first surface, a first connection port being disposed on the second surface; and a second substrate having a third surface and a fourth surface opposite to the third surface. The fourth surface faces the second surface. A second camera module and a signal output port are disposed on the third surface. A second connection port is disposed on the fourth surface. The first connection port is connected with the second connection port. The first camera module on the first surface and the second camera module on the third surface are back-to-back arranged. The first and second camera modules are positioned in the same optical axis. The signal output port serves to output the image signals generated by the first and second camera modules.
