Ledger Document Processing Device Resolution Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slip processing devices face challenges in ensuring consistent image resolution for ledger documents due to varying imaging distances and viewing angles, making it difficult to meet the stipulated resolution requirements for storing images.
Innovation Solution
A slip processing device with a camera and LED indicators that displays a guide frame on the screen to help users adjust the slip area to meet the required resolution, using auto-focus and edge detection to recognize the slip area and adjust the guide frame accordingly, ensuring the stipulated resolution is met before capturing the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image capturing is performed without resolution guidance, then operation simplicity is maintained, but image resolution consistency deteriorates
Solution Approach 1:
A guide frame is introduced as an intermediary visual element between the user and the slip document. The guide frame displays the required imaging area and resolution requirements, mediating the interaction by guiding users to position and capture images at the correct resolution without requiring users to understand technical resolution parameters
Solution Approach 2:
The patent replaces manual resolution judgment and adjustment with automated image processing. The processor automatically evaluates captured images against resolution requirements and provides feedback, substituting the mechanical/manual process of resolution checking with an automated computational system
2Manufacturing precision
If resolution requirements are strictly enforced, then image quality is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-evaluation of captured images by automatically processing and analyzing image resolution quality. The processor evaluates whether captured images meet the required resolution standards and provides automated feedback, allowing the system to serve itself in quality control without requiring manual intervention
Solution Approach 2:
The patent implements a feedback mechanism where the processor analyzes captured images and provides information back to the user about whether resolution requirements are met. This feedback loop enables users to adjust their imaging approach based on system evaluation, ensuring quality without requiring users to manually assess technical parameters

AI summary
A ledger document processing device (1) including a display section (15) which displays a live view image captured by an imaging section while waiting for a ledger document to be captured, and a processor(11) which actualizes functions including judging whether a pixel-count size of an area corresponding to the ledger document in an image to be captured and stored in response to an imaging instruction is equal to or larger than a reference pixel-count size while waiting for the ledger document to be captured, notifying a user of a judgment result, and storing in a storage section the image captured by the imaging section in response to the imaging instruction.
