Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In photoelectric conversion apparatuses, the concentration of loads at a single electrical signal supply unit for analog-to-digital conversion units leads to prolonged stabilization time for signal values, and existing configurations lack a clear description of pixels with integrated analog-to-digital conversion units.
Innovation Solution
A photoelectric conversion apparatus with a pixel array featuring multiple pixels, each equipped with a photoelectric conversion unit, a first and second electrical signal supply unit, and corresponding analog-to-digital conversion units, where the second unit is distinct from the first, reduces load on each supply unit, thereby accelerating signal stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electrical signal supply unit supplies signals to all analog-to-digital conversion units, then device complexity is reduced, but the time for signal values to stabilize increases
Solution Approach 1:
The patent divides the single electrical signal supply unit into multiple separate supply units (first electrical signal supply unit, second electrical signal supply unit, etc.). Each supply unit independently supplies electrical signals to specific analog-to-digital conversion units, thereby segmenting the load and reducing the stabilization time for signal values while maintaining manageable device complexity through systematic distribution.
2Loss of time
If multiple electrical signal supply units are used for analog-to-digital conversion units, then the stabilization time of signal values is reduced, but device complexity increases
Solution Approach 1:
The patent segments the electrical signal supply function into multiple dedicated supply units, where each unit serves specific analog-to-digital conversion units. This segmentation reduces the load on each individual supply unit, thereby reducing signal stabilization time, while the systematic organization of multiple units keeps the overall device complexity manageable.
3Device complexity
If loads are concentrated at a single electrical signal supply unit, then device complexity is reduced, but the operational speed of analog-to-digital conversion decreases
Solution Approach 1:
The patent segments the concentrated load into multiple distributed electrical signal supply units, each handling a subset of analog-to-digital conversion units. This load distribution reduces the burden on each supply unit, enabling faster signal stabilization and thereby increasing the overall operational speed and productivity of the analog-to-digital conversion process.
