Solution Overview

Problem

Conventional devices fail to extract still images from moving images that can be appropriately arranged in a desired layout for printing or photograph albums, often resulting in excessive image selection effort due to aspect ratio differences and lack of template-based extraction conditions.

Innovation Solution

An image processing device and method that determines extraction conditions for still images based on a selected template, analyzing moving image data to extract and position images accordingly, producing layout data for printing or album production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional devices extract still images from moving images without template-based conditions, then more still images can be extracted, but user work to select still images increases

Engineering Contradiction:

Improvenumber of extracted still imagesVSAvoiduser work for selecting still images

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system performs preliminary analysis of the moving image data to determine extraction conditions based on the selected template before actual extraction. This preliminary action identifies which still images should be extracted, reducing the user's subsequent work in selecting appropriate images from a large number of candidates.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically determines extraction conditions and selects still images based on the template requirements without requiring user intervention. The extraction condition determination unit and still image data extraction unit work together to self-select appropriate still images, making the system serve itself rather than requiring user selection.

Inventive Principle:

Principle #25Self-service

2Ease of manufacture

If conventional devices extract still images without considering aspect ratio, then extraction is simpler, but users cannot judge whether extracted images match template requirements

Engineering Contradiction:

Improveextraction process simplicityVSAvoidaspect ratio matching accuracy

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The system incorporates feedback by comparing the aspect ratio of extracted still images with the requirements of the selected template. The determination unit uses this feedback to adjust or confirm extraction conditions, ensuring that extracted images match the template's aspect ratio requirements while maintaining extraction efficiency.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system changes the extraction parameters dynamically based on the template's aspect ratio requirements. When a template with specific aspect ratio is selected, the extraction condition determination unit adjusts the extraction parameters to match, ensuring both extraction efficiency and precision in meeting template specifications.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If conventional devices do not determine extraction conditions based on selected template, then extraction process is faster, but extracted images cannot be appropriately arranged in desired layout

Engineering Contradiction:

Improveextraction processing speedVSAvoidlayout arrangement accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system performs preliminary determination of extraction conditions based on the selected template before actual extraction. This preliminary action configures the extraction parameters according to template requirements, enabling both fast extraction and accurate layout arrangement without requiring post-extraction adjustments.

Inventive Principle:

Principle #10Preliminary action
