Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems, such as monitoring camera systems, face challenges in correcting image degradation due to atmospheric fluctuations, which result in noise amplification and reduced image quality when using the speckle imaging method.
Innovation Solution
An image processing apparatus that acquires parameters affecting atmospheric fluctuations, determines noise reduction methods and conditions based on these parameters, and performs noise reduction processing on input image data to generate corrected images using the speckle imaging method.

Engineering Contradiction Analysis
1Measurement precision
If the speckle imaging method is used to correct atmospheric fluctuation, then image quality is improved, but noise is amplified
Solution Approach 1:
The patent applies noise reduction processing to input image data before performing speckle imaging processing. This preliminary action removes noise from the raw images, preventing noise amplification during the subsequent speckle imaging reconstruction process while maintaining the ability to correct atmospheric fluctuation effects
Solution Approach 2:
The patent introduces an intermediate processing step (noise reduction processing) between image acquisition and speckle imaging reconstruction. This intermediary process acts as a mediator that prepares the input data by reducing noise before the main reconstruction algorithm is applied, thereby improving the quality of the final reconstructed image
