Imaging Apparatus Dedicated AD Conversion Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing imaging apparatus fails to consider a beneficial connection relationship between pixels and analog-to-digital (AD) conversion units when color filters of different colors are disposed on separate pixels, leading to complicated signal processing and AD conversion.
Innovation Solution
The imaging apparatus is configured with a first chip containing pixels of one color and a second chip with AD conversion units, where each AD conversion unit is specifically connected to pixels of a corresponding color, simplifying the AD conversion process by limiting each unit to process signals of only one color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one AD conversion unit carries out AD conversion on signals from pixels with different color filters, then the device complexity is reduced, but the signal processing becomes complicated and correction processing becomes more difficult
Solution Approach 1:
The patent divides the pixel array into multiple regions based on color filter types (e.g., first region with first color filters, second region with second color filters) and assigns each region to a dedicated AD conversion unit. This segmentation ensures that each AD conversion unit processes signals from pixels with the same color filter type, simplifying correction processing while maintaining reasonable device complexity through modular architecture.
Solution Approach 2:
The patent implements local quality by making each AD conversion unit specialized for a specific color filter type. Each unit is optimized to handle the characteristics of its assigned pixel region, enabling more efficient and accurate correction processing for each color channel while maintaining overall system functionality.
2Loss of time
If AD conversion units process multiple color signals, then the processing time is reduced, but the correction processing becomes more complex and time-consuming
Solution Approach 1:
The patent segments the signal processing task by assigning specific color-filtered pixel regions to dedicated AD conversion units. This allows parallel processing of different color channels, reducing overall processing time while keeping each unit's correction processing simple and manageable.
Solution Approach 2:
The patent enables continuous and efficient correction processing by ensuring that each AD conversion unit continuously receives and processes signals from its assigned pixel region without interruption. This specialized assignment eliminates the need for complex multiplexing and switching, maintaining continuous useful action while simplifying correction operations.
