Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Sending raw images from vehicle-mounted cameras to a surveillance center increases communication bandwidth, which is undesirable.

Innovation Solution

An image generation apparatus that processes captured images from vehicles to extract type and positional data, generating reconfigured images for display that include indications of objects and their positions, reducing the need for transmitting full images.

Engineering Contradictions & Design Principles

1Reliability

If raw images are sent to the surveillance center, then visual surveillance capability is maintained, but communication bandwidth increases

Engineering Contradiction:

Improvevisual surveillance capabilityVSAvoidcommunication bandwidth

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential information from the captured images (object type and relative position) and transmits this extracted data to the surveillance center, while the original full images are processed locally to generate reconfigured images for display. This extraction of critical features reduces communication bandwidth while preserving surveillance effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the image processing function into two parts: local processing that generates reconfigured images for display, and data transmission that sends only analyzed information (object type and position) to the surveillance center. This segmentation separates the high-bandwidth visual display function from the low-bandwidth data communication function.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If analysis data is processed and reconfigured images are generated, then communication bandwidth is reduced, but device complexity increases

Engineering Contradiction:

Improvecommunication bandwidthVSAvoidimage processing complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system performs image analysis and reconfiguration locally at the vehicle-mounted device, using its own processing capabilities to generate the surveillance display. This self-service approach eliminates the need for complex centralized processing infrastructure, reducing overall system complexity while enabling bandwidth-efficient communication.

Inventive Principle:

Principle #25Self-service

AI summary

An image generation apparatus (20) includes an acquisition unit (210), a data processing unit (220), and a display (230). The acquisition unit (210) repeatedly acquires analysis data from at least one sending apparatus (10). The analysis data include at least type data and relative position data. The data processing unit (220) generates a reconfigured image by using the analysis data each time the data processing unit (220) acquires the analysis data, and displays the reconfigured image on the display (230). The reconfigured image includes an indication based on the type data in a position associated with the relative position data. The display may be a mark imitating an outer shape of a kind indicated by the type data, or may be an abstract mark.
