Solution Overview

Problem

Current image analysis of camera videos requires high-resolution images, leading to increased processing loads on computers, which existing technologies do not effectively address.

Innovation Solution

A system comprising a first analysis unit that acquires compressed image data, detects data satisfying a predetermined condition, decodes it into higher resolution, and performs further analysis, reducing the processing load by analyzing only selectively decoded high-resolution data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If high resolution image data is used for image analysis, then image analysis accuracy is improved, but processing load increases

Engineering Contradiction:

Improveimage analysis accuracyVSAvoidprocessing load

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the image analysis process into two stages: first analyzing compressed low-resolution image data to identify regions of interest, then decoding and analyzing only those specific regions at high resolution. This segmentation allows the system to maintain high analysis accuracy for critical areas while reducing overall processing load by avoiding full-resolution analysis of entire images.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by differentiating the resolution level applied to different parts of the image data. Compressed low-resolution data is used for initial analysis of the entire image, while high-resolution decoded data is applied only to specific regions that meet predetermined conditions. This ensures high accuracy where needed while optimizing processing resources.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If all image data is decoded to high resolution, then image analysis accuracy is improved, but time required for analysis increases

Engineering Contradiction:

Improveimage analysis accuracyVSAvoidtime required for analysis

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary action by first analyzing compressed low-resolution image data to identify regions of interest before decoding to high resolution. This preliminary screening step filters out areas that do not meet predetermined conditions, allowing the system to save time by avoiding time-consuming high-resolution decoding and analysis of unnecessary regions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies partial action by decoding and analyzing only the necessary portions of image data at high resolution rather than processing the entire image. This selective approach reduces the total time required for analysis while maintaining high accuracy for the regions that require detailed examination.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A first analysis unit (202) acquires second image data. The second image data is generated by compressing first image data by a predetermined encoding method. Further, the first analysis unit (202) performs image analysis of the acquired second image data to detect second image data satisfying a first predetermined condition. A decoding unit (204) decodes second image data detected by the first analysis unit (202) into third image data having higher resolution than that of the second image data. In the second analysis (206), the image analysis of the third image data is performed.
