Printer Image Category Separation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video printers often mix images of different categories on a single sheet of paper, making handling and file management inconvenient, especially in shared environments where multiple users and devices are connected, and there is a need to prevent repeated printing of the same image.
Innovation Solution
A printer system that includes an image memory, printing means, determination means to identify the type of image data, and control means to manage printing based on the type, ensuring that images of different categories are printed on separate sheets and preventing repeated printing by using a thermal or inkjet print head and controlling the printing process to handle image data effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple users and devices share one video printer, then the printer utilization efficiency is improved, but image data of different categories gets mixed on the same recording paper
Solution Approach 1:
The determination means continuously monitors and identifies the category of each input image, providing feedback to the control means. When a category change is detected, the control means automatically intervenes to prevent mixing, ensuring that images of the same category are printed together while maintaining high printer utilization through shared access.
2Ease of operation
If the printer prints images sequentially based on button pressing, then the operation simplicity is improved, but images of different categories are printed on the same sheet
Solution Approach 1:
The determination means automatically identifies and categorizes each input image without requiring user intervention. The control means uses this automatic categorization to manage printing sequences, maintaining operational simplicity while achieving precise category separation through the automated determination and control system.
3Speed
If the printer allows continuous printing without category checks, then the printing speed is improved, but the same image may be repeatedly printed by mistake
Solution Approach 1:
The determination means performs preliminary identification and categorization of each image before the printing process begins. The control means uses this advance categorization information to manage the printing sequence and prevent duplicate printing, enabling fast printing execution while maintaining high reliability through pre-established category identification.
Data Source
AI summary
A mixture of image data in a plurality of categories is prevented from being present on one sheet of recording paper and the handling of printed recording paper is facilitated. Inputted captured image data is saved in order in an image memory. Kinds of the inputted captured image data are determined by the determination section. When the captured image data inputted to the determination section is determined to be of a different kind from the previously inputted image data, the determination section prints through a print head the captured image data previous to the captured image data determined to be of a different kind by the determination section.
