Solution Overview

Problem

Existing image processing systems face challenges in selecting regions of interest (ROIs) efficiently to reduce transmission bandwidth requirements while maintaining image quality.

Innovation Solution

An electronic device and method that selects ROIs based on object danger level values, prioritizing the most dangerous ROI for focus, and optionally adjusting frame rate or selecting additional ROIs to stay within bandwidth limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If complete images are transmitted in high-resolution manner, then image quality is improved, but transmission bandwidth requirement increases

Engineering Contradiction:

Improveimage qualityVSAvoidtransmission bandwidth

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The image is divided into multiple regions of interest (ROIs) based on object danger level values. Instead of transmitting the complete high-resolution image, only the segmented ROI portions requiring attention are transmitted or prioritized, thereby reducing overall transmission bandwidth while maintaining image quality for critical areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different quality levels are applied to different regions of the image based on their danger level. High-resolution transmission is allocated to ROIs with higher danger levels, while lower resolution or reduced transmission is used for less critical regions, optimizing bandwidth usage while preserving image quality where it matters most.

Inventive Principle:

Principle #3Local quality

2Loss of information

If multiple ROIs are selected for transmission, then information completeness is improved, but transmission bandwidth increases

Engineering Contradiction:

Improveinformation completenessVSAvoidtransmission bandwidth

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The system extracts and identifies only the necessary ROI portions from the complete image based on danger level analysis. By taking out only the critical regions that contain important information, the system maintains information completeness for decision-making while significantly reducing the total data volume requiring transmission.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system transmits a partial set of ROIs rather than the complete image, selecting only those regions that exceed certain danger level thresholds. This partial action approach provides sufficient information for monitoring purposes without the excessive bandwidth consumption of transmitting all image data.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Disclosed are an electronic device and a method for selecting a region of interest in an image. The method includes the following steps: receiving an image; using the image to obtain a plurality of regions of interest, wherein each of the plurality of regions of interest corresponds to an object danger level value; and using the object danger level value to select a first region of interest from the plurality of regions of interest.
