Preview Image Generation from File Name Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying preview images of printing files require extensive calculating processes, leading to slow image preview times, especially when dealing with numerous selections.
Innovation Solution
An information processing apparatus that includes a file name reading unit, a preview image generating unit, and a selection display unit, which generates and displays simple preview images based on printing form information from file names, reducing the need to read the image file and allowing quick preview image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a reduced image is generated from the printing image to display as a preview, then the desired printing image can be easily found on a small display screen, but a lot of calculating processes are required and it takes much time to display the preview image
Solution Approach 1:
The system performs preliminary actions by extracting only essential form information (label type, number of printing elements) from the file name before preview display. This preliminary extraction avoids the time-consuming process of generating reduced images from complete printing images, while still providing sufficient information for users to identify desired images quickly.
Solution Approach 2:
The invention extracts only the necessary form information from the file name (such as label type and number of printing elements) rather than processing the entire printing image. This selective extraction eliminates unnecessary calculating processes while retaining the key characteristics needed for image identification.
2Measurement precision
If the file is read from an external device to generate preview, then the preview can be accurate, but the file reading process adds significant time delay
Solution Approach 1:
The system extracts only the essential form information from the file name string itself, without reading the actual file data from external devices. This extraction approach maintains sufficient accuracy for preview purposes (showing label type and printing element count) while completely eliminating the time-consuming file reading process.
Solution Approach 2:
Instead of reading and processing the actual file data, the system creates a simplified copy of the essential information by parsing the file name. This virtual copy contains the necessary form characteristics for preview display without requiring access to the complete file content.

AI summary
An information processing apparatus includes a file name reading unit that reads a file name including form information indicating a printing form of an image to be printed, a preview image generating unit that specifies the printing form from the read file name, and generates a simple preview image of the image based on the printing form, and a selection display unit that displays the simple preview image as a selection for selecting the image which is desired.
