Solution Overview
Problem
Conventional image processing methods either result in low-resolution images or require significant time and resources to achieve high-resolution images, and users often prioritize the resolution of specific image parts.
Innovation Solution
An image processing method that uses different interpolation algorithms for parts of a color-block image within a fixed region and beyond it, where the first algorithm improves resolution and signal-to-noise ratio within the fixed region and a simpler second algorithm is used for the rest, reducing processing time.

Engineering Contradiction Analysis
1Measurement precision
If a first interpolation algorithm is used to convert the color-block image into a simulation image, then the resolution and signal-to-noise ratio are improved, but the processing time and computational resources increase significantly
Solution Approach 1:
The image processing is divided into two segments: a first image corresponding to a first region (main part) and a second image corresponding to a second region (peripheral part). Different interpolation algorithms are applied to each segment, allowing high-resolution processing only where needed while using faster processing for the rest of the image.
Solution Approach 2:
Different quality levels are applied to different regions of the image. The first region receives high-quality processing with a first interpolation algorithm to achieve superior resolution and signal-to-noise ratio, while the second region uses a second interpolation algorithm with lower computational complexity, creating local quality differentiation that optimizes overall processing efficiency.
2Reliability
If a first interpolation algorithm is used to convert the color-block image into a simulation image, then the signal-to-noise ratio is improved, but the computational resources required increase
Solution Approach 1:
The computational workload is segmented by applying different interpolation algorithms to different regions. The first interpolation algorithm with higher computational requirements is applied only to the first region, while the second interpolation algorithm with lower computational requirements is applied to the second region, reducing overall computational resource consumption.
Solution Approach 2:
High signal-to-noise ratio processing is applied locally to the first region where it is most needed, while the second region accepts lower-quality processing. This local differentiation maintains reliability where critical while reducing overall computational complexity.
3Productivity
If conventional image processing methods are used, then the processing is simple and fast, but the obtained image has low resolution
Solution Approach 1:
The image is segmented into a first region requiring high resolution and a second region where speed is prioritized. This segmentation allows the system to achieve high resolution in critical areas without applying computationally intensive algorithms to the entire image, thus maintaining overall processing efficiency.
Solution Approach 2:
Different quality levels are applied to different regions: high-resolution processing for the first region and standard processing for the second region. This creates a differentiated quality approach that improves resolution where needed while maintaining fast processing overall.

AI summary
An image processing method and apparatus, a control method are provided. A part of the color-block image within the fixed region is converted into a first image using a first interpolation algorithm. The first image includes first simulation pixels arranged in an array. A part of the color-block image beyond the fixed region is converted into a second image using a second interpolation algorithm. The second image includes second simulation pixels arranged in an array, and a complexity of the second interpolation algorithm is less than that of the first interpolation algorithm. The first image and the second image are merged into a simulation image corresponding to the color-block image. With the image processing method, by processing different parts of the image respectively with the first interpolation algorithm and the second, the time for processing the image is reduced while the image quality is improved, thus improving the user satisfaction.
