Image Pickup Apparatus Dust Removal via Display Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses, such as single-lens reflex digital cameras, face challenges in completely preventing dust and grid adhesion to optical components during lens interchange, leading to potential image contamination, and existing solutions either incompletely suppress adhesion or require prior white image photography for dust profile creation.
Innovation Solution
An image pickup apparatus with a detecting portion to specify the position of dust and grid on the captured image through user manipulation on a display surface, allowing for targeted image processing to remove these artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical suppression methods (charging device, dust correcting plate, air flow) are used to prevent dust adhesion, then dust adhesion is suppressed, but adhesion cannot be perfectly prevented and grid and dust images may still appear on photographed images
Solution Approach 1:
The patent performs preliminary action by capturing a white image before actual photography to create a dust profile. This profile is stored and then used during image processing to identify and remove dust and grid artifacts from the final photographed image, allowing for effective removal without requiring perfect physical prevention
Solution Approach 2:
The patent creates a copy (dust profile) of the dust and grid distribution pattern by photographing a white image. This profile serves as a reference template that is then used during image processing to accurately identify and remove corresponding artifacts from the actual photographed image, enabling precise dust removal without physical intervention
2Object-affected harmful factors
If white image photography is performed to create dust profile for dust removal, then grid and dust can be removed from photographed images, but the process becomes more complex and time-consuming due to the additional white image capture requirement
Solution Approach 1:
The patent applies self-service by having the system automatically capture the white image, generate the dust profile, and execute the image processing to remove dust and grid artifacts without requiring manual intervention. The camera system serves itself by automatically performing the entire dust removal workflow including the white image capture, profile creation, and artifact removal processing
3Ease of operation
If manual dust removal methods are used, then dust adhesion can be addressed, but the process requires user intervention and is not automated
Solution Approach 1:
The patent implements self-service automation where the camera system automatically captures the white image, generates the dust profile, and executes the image processing to remove dust and grid artifacts without requiring manual intervention. The entire dust removal workflow is automated by the camera system itself
Solution Approach 2:
The patent uses feedback by capturing a white image to create a dust profile that serves as a reference template. This profile is then fed back into the image processing system to automatically identify and remove corresponding dust and grid artifacts from the final photographed image, enabling automated dust removal based on the captured dust distribution pattern
