Solution Overview
Problem
Vehicle camera modules face increased processing time and error probability when transmitting images to image processing devices, particularly in autonomous driving applications, due to the need for repeated image processing and potential delays in transmitting images from multiple cameras.
Innovation Solution
A vehicle camera module with an integrated image transmission processor that determines whether to compress images based on format or preset options, using lossless or lossy compression to rapidly transmit images to external devices, thereby reducing processing time and error likelihood.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed by the vehicle camera module itself before transmission, then the image quality and processing accuracy are improved, but the transmission time is increased and the overall system efficiency deteriorates
Solution Approach 1:
The patent extracts the image processing function from the vehicle camera module and relocates it to the central processor. The camera module only captures raw images and transmits them immediately, while the central processor performs all image processing operations. This separation eliminates the time delay caused by on-module processing while maintaining image quality, as the central processor has sufficient computational power to handle the processing tasks without delaying transmission.
2Adaptability or versatility
If multiple vehicle camera modules transmit images to the image processing device, then the coverage and monitoring capability are improved, but the processing time and error probability increase due to repeated processing
Solution Approach 1:
The patent merges all image processing operations into a single centralized processor that receives images from multiple camera modules. Instead of each camera module independently processing its images, the central processor consolidates all processing tasks, eliminating redundant operations. This approach maintains the comprehensive monitoring capability provided by multiple cameras while significantly reducing total processing time by avoiding repeated processing of the same image data across multiple devices.
3Manufacturing precision
If images are transmitted without compression from multiple cameras, then the image quality is preserved, but the transmission bandwidth and processing load increase
Solution Approach 1:
The patent changes the parameter of image data representation by implementing compression algorithms in the central processor. The system transmits images in a compressed format to reduce bandwidth requirements and processing load, while the central processor's computational power enables it to decompress and process the images with minimal quality loss. This parameter change allows the system to maintain high image quality standards while significantly improving transmission efficiency and reducing the processing burden on the system.

AI summary
A vehicle camera module may include: an image sensor; and an image transmission processor that may determine whether to compress or not compress an image captured through the image sensor according to the format of the image or a preset option, and output the compressed or non-compressed image to an external image output device. The image sensor and the image transmission processor may be implemented as an integrated module.
