Solution Overview

Problem

Existing image processing systems face difficulties in displaying large documents efficiently on small screens, particularly in ensuring that title sections and other critical information are easily readable, and in handling documents of varying orientations and sizes.

Innovation Solution

An image processing apparatus that generates preview image data and uses a display controller to display a partial image of the document in a specific area, rotating the image if necessary to ensure it is upright and readable, while maintaining a processing load by only rotating preview image data and not the actual scan data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the entire document image is displayed on a small screen, then the complete document content is visible, but the title section and critical information become difficult to read due to size constraints

Engineering Contradiction:

Improvedisplay areaVSAvoidreadability of critical information

Core Design Contradiction:

Area of stationary objectVSLoss of information

Solution Approach 1:

The display area is segmented into multiple regions: a first display area showing the title section at a larger size and a second display area showing other document portions. This segmentation allows critical information to be prominently displayed while still providing access to the complete document content through the additional display area.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the document image is rotated to match the display orientation, then the document becomes readable, but the processing load increases significantly

Engineering Contradiction:

ImprovereadabilityVSAvoidprocessing load

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The title section is extracted from the entire document image and processed separately. By identifying and isolating the title section, the system can rotate only the necessary portions of the image rather than the entire document, significantly reducing the processing load while maintaining readability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary analysis to identify the title section and determine the required rotation angle before executing the rotation operation. This preliminary action allows the system to prepare the rotation parameters in advance, optimizing the processing efficiency and reducing the overall computational burden.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the system handles documents of various orientations and sizes, then the system becomes more versatile, but the complexity of determining the correct display orientation increases

Engineering Contradiction:

Improvedocument handling capabilityVSAvoidorientation detection complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs automatic orientation detection that analyzes the document image itself to determine the correct display orientation. By using self-service mechanisms such as detecting text orientation, title section position, and document structure, the system adapts to various document orientations and sizes without requiring manual intervention or complex external processing.

Inventive Principle:

Principle #25Self-service
