Vehicle Black Box Image Encoding Mode Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for determining the encoding mode for images recorded in a vehicle's black box are time-consuming due to complex computing processes, especially when distinguishing between intra and inter modes based on motion estimation and prediction.
Innovation Solution
An apparatus and method that utilize an information collector to gather road or traffic information, which is then used by a mode determiner to decide between intra and inter encoding modes, with a controller managing the encoding process, thereby simplifying the determination and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion estimation and compensation are performed to determine encoding mode, then encoding accuracy is improved, but encoding time increases
Solution Approach 1:
The patent applies preliminary action by pre-collecting road information (suburban road or city road) before the encoding process. The mode determiner uses this pre-collected information to directly determine the encoding mode without performing time-consuming motion estimation and compensation, thus resolving the contradiction between accuracy and time by performing the determination action in advance
Solution Approach 2:
The patent extracts the motion estimation and compensation process from the encoding mode determination process. Instead of using motion estimation to determine encoding mode, the patent extracts road information as a separate input and uses it directly to determine the mode, eliminating the need for complex motion analysis while maintaining determination accuracy
2Measurement precision
If complex computing processes are used to compare energy of predicted residual signal with original image, then encoding mode determination accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent extracts road information as a separate input source from the complex energy comparison process. The mode determiner uses this extracted road information to directly determine encoding mode, completely removing the need for complex computing processes involving energy comparison of predicted residual signals with original images
Solution Approach 2:
The patent replaces complex, resource-intensive energy comparison computations with simple, lightweight road information lookup. This substitution uses inexpensive, readily available road information data to determine encoding mode, eliminating the need for expensive computational processes while maintaining determination accuracy

AI summary
The apparatus for processing an image recorded in a black box for a vehicle includes an information collector, a mode determiner, an encoder and a controller. The information collector is configured to collect information on a road on which a vehicle is being driven. The mode determiner is configured to determine an inter mode when the road information collected by the information collector indicates a suburban road and determine an intra mode when the road information indicates a city road. The encoder is configured to encode the image recorded in the black box. The controller is configured to control the encoder to encode the image with an encoding mode determined by the mode determiner.
