Vehicle Camera Image Enlargement for Delay Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The delay in image display on vehicle monitoring systems makes it difficult for drivers to accurately assess the approaching state of other vehicles, particularly during operations like lane changes, as the images displayed are not in real-time, affecting driving safety.
Innovation Solution
An image display control device that includes a vehicle detection unit, enlargement unit, and output unit, which detects other vehicles and applies enlargement processing based on the delay time required for image display, ensuring the displayed image size is closer to real-time, thereby improving driver awareness of approaching vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If images are displayed on a monitor using a camera system, then the driver can check the rear and side of the vehicle, but the images delay with respect to real-time images due to processing time
Solution Approach 1:
The system performs preliminary detection of other vehicles and calculates their approach speed before the image is fully processed and displayed. This allows the system to pre-calculate the expected position and size of the vehicle in the delayed image, applying compensation adjustments that make the delayed image reflect the real-time situation more accurately.
Solution Approach 2:
The system changes the display parameters of the image (such as size, position, or magnification) based on the detected approach speed and delay time. By dynamically adjusting these parameters, the system compensates for the delay effect, making the displayed image more representative of the current real-time situation.
2Loss of information
If the driver relies on delayed monitor images to check approaching vehicles, then the system provides visual information, but the driver cannot accurately grasp the approaching state of other vehicles
Solution Approach 1:
The system continuously detects the position and speed of other vehicles, calculates the delay compensation amount, and adjusts the display parameters accordingly. This feedback loop ensures that the displayed image consistently reflects the current real-time situation despite the inherent processing delay.
Solution Approach 2:
The system dynamically changes display parameters (such as image size or magnification) based on the calculated approach speed and delay time, allowing the driver to accurately assess the approaching state even with delayed images.

AI summary
An image display control device displays, on a monitor, images of the periphery of a vehicle that are captured by a left camera and a right camera installed in the vehicle. The device includes: a vehicle detection unit which detects another vehicle from the images captured by the left camera and the right camera; an enlargement unit which, when the other vehicle is detected by the vehicle detection unit, subjects the images captured by the left camera and the right camera to enlargement processing on the basis of a delay time the images take to be displayed on the monitor; and an output unit which outputs the images subjected to the enlargement processing by the enlargement unit to the monitor.
