Engineering Contradiction Analysis
1Reliability
If the preprocessing chip is disposed on the main board, then the image or video data can be processed, but the area of the main board increases and costs increase
Solution Approach 1:
The preprocessing chip is extracted from the main board and integrated into the camera module. This removes the problematic component from the main board, reducing its area while preserving the image and video data processing capability through the integrated preprocessing chip in the camera module.
Solution Approach 2:
The preprocessing chip is merged with the camera module, combining two previously separate components into a single integrated unit. This integration allows the preprocessing function to be achieved without occupying additional space on the main board, as the preprocessing chip shares the camera module's space.
2Reliability
If the preprocessing chip is disposed on the main board, then the image or video data can be processed, but the costs increase
Solution Approach 1:
The preprocessing chip is extracted from the main board and relocated to the camera module. This extraction eliminates the need for additional main board space and reduces manufacturing complexity, thereby lowering production costs while maintaining the image and video data processing capability.
Solution Approach 2:
The preprocessing chip is merged with the camera module, consolidating components into a single module. This merging reduces the overall number of components that need to be manufactured and assembled, simplifying the manufacturing process and reducing costs while preserving the preprocessing function.
3Reliability
If the preprocessing chip is disposed on the main board, then the image or video data can be processed, but the main board complexity increases
Solution Approach 1:
The preprocessing chip is extracted from the main board and integrated into the camera module. This removal eliminates the complexity associated with routing, power supply, and signal integration on the main board, thereby reducing main board complexity while maintaining the image and video data processing capability through the integrated system.
Solution Approach 2:
The preprocessing chip is merged with the camera module, consolidating multiple functions into a single integrated unit. This merging reduces the number of separate components and connection paths on the main board, thereby simplifying the main board design and reducing complexity while preserving the preprocessing function.

AI summary
An electronic device and a camera module are provided. An image signal processor integrated circuit and a first switch are disposed in the camera module, and the first switch can implement a single pole double throw function between a camera and two paths. In this way, through switching performed by using the first switch, image data acquired by the camera may be directly transmitted to a processor through a first path; or the image data acquired by the camera is processed by the image signal processor integrated circuit in a second path, and processed image data is transmitted to the processor.
