Vehicle Image Processing Apparatus for Efficient Parking Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in efficiently storing and displaying numerous images due to high storage costs and the inconvenience of searching through large datasets, often resulting in old images being deleted due to insufficient storage capacity during long parking periods.
Innovation Solution
An image processing apparatus that compresses and stores identical pixels as a single key frame, while separately compressing and storing different pixels as delta frames, allowing for efficient restoration and synthesis for display, along with matching and displaying images with time information, and adjusting brightness and color based on environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If images are stored in real-time with high storage capacity, then image acquisition function is improved, but unit cost is increased
Solution Approach 1:
The patent merges multiple consecutive images into a single composite image by identifying and combining identical pixel regions. This reduces the total number of images that need to be stored while preserving all unique visual information, thereby decreasing storage capacity requirements and associated costs.
Solution Approach 2:
The composite image serves multiple functions: it preserves all unique visual elements from multiple source images, enables cost-effective storage, and maintains the ability to retrieve information from any time point. This multi-functionality eliminates the need for separate high-capacity storage systems.
2Loss of information
If all stored images are displayed one by one, then complete image information is provided, but search time is increased
Solution Approach 1:
The patent overlays multiple delta frames (representing different time points) onto a single key frame simultaneously. This merging allows users to view information from multiple time points in one display, eliminating the need to sequentially search through individual images and significantly reducing search time while preserving complete image information.
Solution Approach 2:
The patent transitions from temporal sequencing (displaying images one after another in time order) to spatial overlay (displaying multiple time points simultaneously in a single visual field). This dimensional change from time to space allows complete image information to be accessed instantly without sequential searching.
3Duration of action of moving object
If multiple images are stored during long parking, then image coverage is improved, but storage capacity is exhausted
Solution Approach 1:
The patent merges consecutive images into composite images, dramatically reducing the number of individual image files that need to be stored. This merging approach extends the duration of image storage during long parking periods by reducing the rate at which storage capacity is consumed, allowing historical images to be retained without exhausting available storage.

AI summary
A vehicle is provided and includes an image acquisition device and an image processing apparatus that receives an original frame for an image obtained by the image acquisition device at a set time interval in the parking state and obtains a key frame having the same pixel with each other by comparing a plurality of original frames received at the set time interval. The image processing apparatus obtains a plurality of delta frames having pixels different from the reference original frame from remaining original frames by comparing each of the reference original frame and the remaining original frames among the plurality of frames and compresses the key frame and the plurality of delta frames, respectively. A storage device stores the key frame and a plurality of delta frames compressed by the image processing apparatus.
