Image Processing Apparatus Copy Forgery Pattern Density Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies face challenges in reducing printing costs while maintaining the effectiveness of copy forgery inhibited patterns, as setting the saving mode invalidates the pattern's security effect and prioritizing the pattern over saving mode increases toner consumption, and vice versa, leading to compromised visibility due to density differences.
Innovation Solution
An image processing apparatus that dynamically adjusts the density of the copy forgery inhibited pattern image based on whether the saving mode is set, ensuring the pattern's density is lower in saving mode to reduce toner and ink consumption while maintaining security and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the copy forgery inhibited pattern image is printed at the same density in saving mode, then the security effect is maintained, but toner consumption is not reduced
Solution Approach 1:
The patent applies dynamics by making the pattern density adjustable rather than fixed. The control unit dynamically changes the pattern density based on the printing mode (normal or saving mode), allowing the system to adapt between security requirements and cost savings. In saving mode, the pattern density is reduced while still maintaining anti-counterfeiting functionality, thereby reducing toner consumption without completely sacrificing security.
Solution Approach 2:
The patent changes the density parameter of the copy forgery inhibited pattern image based on the printing mode. In normal mode, the pattern is printed at standard density to ensure maximum security effect. In saving mode, the pattern density is reduced to lower toner consumption. This parameter adjustment resolves the contradiction between maintaining security and reducing material usage.
2Loss of substance
If the saving mode is applied to the copy forgery inhibited pattern image, then toner consumption is reduced, but the latent image part does not stand out and security effect is lost
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different parts of the printed output. The copy forgery inhibited pattern image (including latent image and background parts) is printed at a different density than the main document content in saving mode. This localized density adjustment ensures that the pattern remains visible enough to provide security while the overall document consumes less toner.
Solution Approach 2:
The system dynamically adjusts pattern density based on mode selection. The control unit receives printing mode information and accordingly modifies the pattern density parameter before sending data to the printing unit. This dynamic adjustment allows the pattern to adapt its visibility and toner consumption characteristics to match the current operational requirements.
3Loss of substance
If the density of the copy forgery inhibited pattern image is reduced in saving mode, then toner consumption is reduced and visibility is maintained, but the contrast between image and pattern is reduced
Solution Approach 1:
The patent changes the density parameter of the pattern image in saving mode to achieve a balance between toner consumption and visibility. By reducing pattern density rather than eliminating it, the system maintains sufficient contrast for the pattern to remain visible and functional, while significantly reducing toner usage compared to printing at full density.

AI summary
By addition of a copy forgery inhibited pattern image having a lower density to an image in a saving mode, there is provided an image processing apparatus which can reduce consumption amounts of toner and ink while keeping effectiveness of the copy forgery inhibited pattern image. The present invention is an image processing apparatus having a copy forgery inhibited pattern image addition mode and a saving mode, and includes a unit configured to determine whether the copy forgery inhibited pattern image addition mode is set and a unit configured to determine whether the saving mode is set, wherein a density of the copy forgery inhibited pattern image to be added to the image in the case where the saving mode is set is lower than a density of the copy forgery inhibited pattern image to be added to the image in the case where the saving mode isn't set.
