Solution Overview

Problem

Existing image processing determination methods face challenges in adjusting accuracy and time required for determining the presence or absence of image processing.

Innovation Solution

A determination device and method that repeatedly acquires partial images of a target image until a predetermined end condition is met, calculating a score for each partial image to determine the presence or absence of processing, allowing for adjustable accuracy and time through dynamic threshold value adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a separation module is trained using a training data set including processed and unprocessed images to determine image processing presence or absence, then determination accuracy is improved, but the time required for determination increases

Engineering Contradiction:

Improvedetermination accuracyVSAvoidtime required for determination

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent divides the image into multiple partial images and processes them separately through the trained separation module. This segmentation approach allows the system to achieve high determination accuracy by analyzing multiple regions while managing processing time through parallel or sequential processing of smaller image segments rather than processing the entire image at once.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a determination process that can stop early when a predetermined end condition is met, meaning not all partial images need to be processed to achieve sufficient accuracy. This partial action approach reduces the time required for determination while maintaining adequate accuracy by processing only the necessary number of partial images.

Inventive Principle:

Principle #16Partial or excessive action

2Measurement precision

If multiple partial images are acquired and processed to improve determination accuracy, then determination accuracy is improved, but the processing time increases

Engineering Contradiction:

Improvedetermination accuracyVSAvoidprocessing speed

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The system processes partial images until a predetermined end condition is established, meaning it stops processing when sufficient accuracy is achieved rather than processing all possible partial images. This allows the system to balance accuracy and processing speed by performing only the necessary amount of processing.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The determination process is designed to be dynamic, adjusting the number of partial images processed based on the end condition. This dynamic approach allows the system to adapt processing time to the specific characteristics of each image, maintaining high accuracy while optimizing processing speed for each case.

Inventive Principle:

Principle #15Dynamics

AI summary

A determination device includes a partial image acquisition unit that repeatedly acquires a partial image of a target image until a predetermined end condition is established, a score calculation unit that calculates a score related to the presence or absence of processing of the partial image in each time the partial image acquisition unit acquires the partial image, and a processing determination unit that determines the presence or absence of processing of the target image on the basis of the score.
