Image Processing Apparatus for Superimposed Image Sharpness Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When images from multiple devices are superimposed, the sharpness of the resulting image is lower than the input image due to differences in resolution, particularly when a projector and a printer are used, as the projector's resolution decreases with increased image size, leading to incomplete representation of input image data.
Innovation Solution
An image processing apparatus that adjusts the resolution of images output by different devices to ensure the sharpness of the superimposed image is maintained by calculating the decrease in sharpness and emphasizing it through specific processing steps, such as resolution conversion and high-pass filtering, to compensate for the projector's resolution loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the image size is increased by the projector, then the image can cover a larger area, but the resolution decreases and sharpness is lost
Solution Approach 1:
The image is segmented into two parts: a printed image portion (high resolution) and a projected image portion (lower resolution but larger area). This segmentation allows each device to operate at its optimal resolution while achieving both high overall resolution and large coverage area through superposition
Solution Approach 2:
The system changes the resolution parameter dynamically by using the printer for high-resolution output and the projector for large-area coverage. The image processing apparatus adjusts the division ratio and positions based on desired output characteristics, allowing flexible parameter optimization
2Area of stationary object
If multiple devices are used to superimpose images, then both high resolution and large area can be achieved, but the sharpness of the superimposed image becomes lower than the input image
Solution Approach 1:
Different regions of the final image have different quality characteristics: the printed portion maintains high sharpness and resolution, while the projected portion provides extended area coverage. The image processing apparatus strategically assigns different image portions to different devices based on their respective strengths
Solution Approach 2:
The image is pre-processed by the image processing apparatus to divide it into appropriate portions for each device before output. This preliminary segmentation ensures that when images are superimposed, the sharpness degradation is minimized by optimizing the division ratio and positioning
3Productivity
If the same image data is input to both printer and projector, then both devices can operate simultaneously, but the projector's lower resolution causes information loss
Solution Approach 1:
The image data is segmented into different portions that are optimally suited for each device. The printer receives portions requiring high resolution, while the projector receives portions where area coverage is more important, preventing information loss through appropriate division
Solution Approach 2:
The system changes the output parameters for each device based on their capabilities. The image processing apparatus adjusts resolution, size, and position parameters differently for printer and projector outputs, ensuring each device operates at optimal parameters while preserving image information
