Rear-View Camera Readout Control for Vehicle Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-capturing systems for vehicles face challenges in providing an optimal image for vehicle operation, especially when the vehicle is inclined, leading to changes in the ratio of sky, road, and other elements in the captured image, which can reduce the information available to the driver.
Innovation Solution
An image-capturing apparatus and control method that uses a controller to adjust the reading of images from an image sensor based on vehicle information, such as inclination, to maintain a consistent image size and proportion, ensuring that the driver receives a suitable image for vehicle operation regardless of the vehicle's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a large captured image is read from the camera to cut out the necessary image when the vehicle is inclined, then the necessary image can be provided, but the frame rate decreases
Solution Approach 1:
The patent pre-calculates and stores the position and size of the necessary image region based on vehicle inclination information before the actual image capture. When the vehicle is inclined, the system can directly read only the pre-determined necessary region from the image sensor, avoiding the need to read and then crop a large captured image, thus maintaining high frame rate while providing the required image quality
Solution Approach 2:
The patent dynamically adjusts the reading position and size of the image from the image sensor based on real-time vehicle inclination information. The controller modifies the readout region coordinates according to the inclination angle, enabling the system to adaptively capture only the necessary portion of the scene, thereby optimizing both image quality and frame rate under varying vehicle conditions
2Ease of operation
If the viewing system is adjusted for a flat road surface, then a suitable BM image is displayed on flat roads, but the image becomes unsuitable when the vehicle is inclined
Solution Approach 1:
The patent changes the reading parameters (position and size) of the image from the image sensor based on vehicle inclination information. When the vehicle is inclined, the controller adjusts the readout region coordinates to compensate for the inclination, ensuring that the necessary image content (such as the road and obstacles) remains within the captured frame, thus maintaining image suitability across different road conditions
Solution Approach 2:
The patent uses vehicle inclination information as feedback to dynamically adjust the image reading parameters. The controller continuously monitors the vehicle's inclination state and modifies the image capture region accordingly, creating a closed-loop system that adapts to changing road conditions and maintains optimal image quality for driver awareness

AI summary
An image-capturing apparatus, a control method, and a program that make it possible to easily provide an image suitable for the operation of a vehicle. The controller controls reading of an image from an image sensor that captures the image, on the basis of vehicle information acquired by a vehicle, the image being displayed on a display section of the vehicle. Embodiments may be applicable to a viewing system that displays an image of a region behind a vehicle.
