Image Sensor Alien Substance Removal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image sensing apparatuses experience release time lag due to alien substance removal operations, which can result in missed shutter release opportunities during continuous shooting modes.
Innovation Solution
An image sensing apparatus with an alien substance removing unit and a control unit that interrupts the alien substance removal operation when a photographic operation request is input, allowing immediate execution of the requested operation without delaying the photographic process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If alien substance removal operation is executed before photographing, then image quality is improved by removing dust, but release time lag increases and continuous shot speed is reduced
Solution Approach 1:
The system dynamically adjusts the priority between alien substance removal and photographic operations. When a photographic operation request is received during alien substance removal, the system interrupts the removal operation to execute the photographic operation immediately, making the system flexible and adaptive to user needs rather than following a fixed sequence
Solution Approach 2:
The alien substance removal operation is designed to be periodically executable rather than mandatory before each shot. The system can perform removal at power-on, during idle periods, or when explicitly requested, but allows photographic operations to take precedence, creating a periodic rather than continuous removal schedule that doesn't interfere with shooting opportunities
2Manufacturing precision
If alien substance removal is executed continuously, then image quality is maintained, but productivity decreases due to release time lag
Solution Approach 1:
The system dynamically prioritizes photographic operations over alien substance removal operations. When a shutter release or other photographic operation is requested during alien substance removal, the system interrupts the removal operation to execute the photographic operation immediately, ensuring continuous shooting capability is maintained
Solution Approach 2:
Instead of performing complete alien substance removal before every shot, the system performs removal only when no photographic operation is pending. This partial action approach (removal only during idle periods) is sufficient to maintain image quality while avoiding the excessive action of interrupting continuous shooting sequences

AI summary
In a case where a request for an operation related to photographic operation is input during an alien substance removing operation of removing an alien substance sticking to an optical element arranged in front of an image sensing element, the alien substance removing operation is interrupted, and then the processing corresponding to the request for the photographic operation is executed.
