Image Processing Apparatus Adding Specific Images in Color and Black-and-White Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing apparatuses fail to protect confidential black-and-white images by not adding a specific image during processing, leading to unauthorized use and security risks, as they only add such images in color mode.
Innovation Solution
The apparatus adds a specific image in both color and black-and-white modes, with a lower security level in black-and-white mode, ensuring that a specific image is included even in black-and-white image data processing, thereby restricting unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific image is added only in color mode, then the security measure is simple to implement, but black-and-white confidential images are not protected leading to unauthorized use
Solution Approach 1:
The specific image adding section is designed to add specific images in both color mode and black-and-white mode, making the security measure universal across different image processing modes. This resolves the contradiction by extending the protection capability to cover all image types, not just color images.
Solution Approach 2:
Different specific images are used for color mode and black-and-white mode respectively. The specific image adding section determines the image mode and selects appropriate specific images, allowing each mode to have optimized protection while maintaining overall system reliability.
2Reliability
If different specific images are used for color and black-and-white modes, then appropriate protection is provided for each mode, but the device complexity increases
Solution Approach 1:
The specific image adding section implements local quality by using different specific images for different image modes (color vs. black-and-white). The section determines the mode and selects appropriate specific images, providing optimized security for each mode while managing complexity through structured decision-making.
Solution Approach 2:
The system changes the parameter of specific image selection based on image mode. By determining whether the input is color or black-and-white mode and selecting corresponding specific images, the system achieves mode-appropriate security without excessive complexity.
3Reliability
If a specific image is added in black-and-white mode, then confidential black-and-white images are protected, but processing time increases
Solution Approach 1:
The specific image adding section determines the image mode (color or black-and-white) at the beginning of processing and selects the appropriate specific image accordingly. This preliminary determination allows for efficient processing by avoiding unnecessary operations and directly adding the correct specific image for the detected mode.

AI summary
An image processing apparatus for preventing unauthorized uses of image data by allowing the addition of a specific image in a black-and-white mode even when it is set that a specific image is added in a color mode. When a document is copied, a control section determines whether the apparatus is in a color mode or a black-and-white mode. When in a black-and-white mode, an adding condition determining section reads a set security level and a differential value and determines a security level lower than the one in a color mode. Based on the security level in a black-and-white mode, an adding condition of a specific image is determined. The specific image adding section adds a specific image different from the one in a color mode based on the adding condition. A black-and-white image added with the specific image is printed.
