Semi-Transparent Pattern Scaling with Multivaluing and Patterning Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for scaling semi-transparent objects often result in image deterioration, particularly when using nearest neighbor or black pixel saving methods, which distort the pattern and degrade image quality.
Innovation Solution
An information processing apparatus and method that performs multivaluing processing on semi-transparent patterns, followed by scaling and applying a patterning screen in rectangular units to maintain the shape and transparency of the pattern, using weighted averaging or pixel ratio calculations to prevent distortion.

Engineering Contradiction Analysis
1Productivity
If nearest neighbor or black pixel saving method is used for scaling semi-transparent objects, then scaling operation is simple and fast, but image quality deteriorates and pattern distortion occurs
Solution Approach 1:
The patent applies preliminary action by performing multivaluing processing on the semi-transparent pattern before scaling. This converts the binary pattern into a multivalued image with density information, allowing the pattern to maintain its integrity during subsequent scaling operations. The preliminary conversion prevents distortion by establishing a more robust representation that can withstand scaling transformations.
Solution Approach 2:
The patent changes the parameter representation of the semi-transparent pattern from binary (on/off pixels only) to multivalued (including density information). This parameter change allows the pattern to preserve its visual characteristics during scaling, as the density values provide intermediate states that prevent the harsh transitions and distortion seen in binary scaling methods.
2Ease of operation
If conventional scaling methods are used on semi-transparent patterns, then processing is straightforward, but the shape and transparency of the original pattern are distorted
Solution Approach 1:
The patent applies preliminary action by performing multivaluing processing on the semi-transparent pattern before scaling. This converts the binary pattern into a multivalued image with density information, allowing the pattern to maintain its integrity during subsequent scaling operations. The preliminary conversion prevents distortion by establishing a more robust representation that can withstand scaling transformations.
Solution Approach 2:
The patent introduces a patterning screen as an intermediary element during the scaling process. This screen is applied in rectangular units to the multivalued semi-transparent pattern, acting as a mediator that preserves the original pattern's shape and transparency characteristics while allowing scaling to occur. The screen provides a structured framework that guides the scaling operation to maintain fidelity.
3Manufacturing precision
If multivaluing processing and patterning screen are applied to maintain pattern quality, then image quality is preserved, but processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the patterning screen application into rectangular units. Instead of applying the screen to the entire image at once, it processes the image in manageable rectangular segments. This segmentation reduces the computational complexity of each individual operation while maintaining the overall quality improvement, making the complex process more efficient and implementable.
