Multi-Angle On-Vehicle Camera Sensor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-vehicle camera systems with zoom mechanisms are costly and inefficient for simultaneous execution of multiple applications requiring different angles of view, such as lane detection and obstacle detection, due to increased size and processing time, especially for real-time operations.
Innovation Solution
A camera system capable of processing multiple applications with different required angles of view simultaneously by dividing the screen into multiple areas with distinct angles of view, allowing concurrent image processing without the need for frequent angle changes, reducing processing time and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a zoom mechanism is used to change the angle of view, then the camera can pick up images at multiple angles, but the camera size and cost increase
Solution Approach 1:
The patent divides the image sensor into multiple regions, with each region capturing an image at a different angle of view. This segmentation approach eliminates the need for a zoom mechanism while still achieving multi-angle imaging capability, thus reducing camera size and cost.
Solution Approach 2:
Instead of changing the angle of view through mechanical zooming (one dimension), the patent uses spatial division of the sensor surface to capture multiple angles simultaneously (another dimension). This transforms the problem from temporal/m mechanical to spatial solution.
2Adaptability or versatility
If the zoom mechanism switches between wide and narrow angles for different applications, then the required angle of view can be adjusted, but the processing time increases
Solution Approach 1:
The patent pre-divides the image sensor into multiple regions that capture different angles of view simultaneously. This preliminary spatial arrangement allows multiple applications to access their required angle data without waiting for sequential zoom adjustments, thereby reducing processing time.
Solution Approach 2:
The patent enables continuous capture of multiple angles simultaneously through the divided sensor regions, rather than sequential zooming. This continuous multi-angle acquisition eliminates the time loss associated with switching between wide and narrow angles for different applications.
3Adaptability or versatility
If a single camera captures images for multiple applications with different angles, then the device can perform various functions, but the processing complexity increases
Solution Approach 1:
The patent segments the image sensor into distinct regions, each dedicated to capturing specific angle data for different applications. This segmentation simplifies processing by assigning specific spatial regions to specific functions, reducing the complexity of managing multiple angle views through a single camera.

AI summary
A camera with two or more angles of view is disclosed. An imaging processing for a first application is carried out at a first angle of view on the same image data, and the imaging processing for a second application is carried out at a second angle of view different from the first angle of view on the same image data, the first and second image processing being carried out in the same period. To achieve this object, the same screen is divided into a plurality of screens having a plurality of angles of view, and the image processing for a plurality of applications is carried out using any one of the screens with the angles of view divided, the plurality of the applications being processed in the same period.
