IMAGE SENSING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240282786 titled 'IMAGE SENSING DEVICE
The patent application describes an image sensing device with multiple pixel arrays, including a first pixel array with first unit pixels and a second pixel array surrounding the first array with second unit pixels. Each first unit pixel in the first array contains multiple photodiodes connected to different transfer transistors.
- The image sensing device consists of multiple pixel arrays.
- The first pixel array contains first unit pixels.
- The second pixel array surrounds the first array and includes second unit pixels.
- Each first unit pixel has multiple photodiodes.
- Each photodiode in the first unit pixel is connected to a different transfer transistor.
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Improved image quality - Enhanced low-light performance - Higher resolution images
Benefits: - Higher sensitivity - Reduced noise levels - Enhanced image clarity
Commercial Applications: Title: Advanced Image Sensing Technology for Enhanced Surveillance Systems This technology can be used in security cameras for improved image quality and low-light performance, making it ideal for commercial surveillance applications.
Questions about Image Sensing Devices: 1. How does the use of multiple photodiodes in each pixel improve image quality?
- The use of multiple photodiodes allows for increased sensitivity to light, resulting in clearer and more detailed images.
2. What are the advantages of having transfer transistors connected to each photodiode?
- The connection to transfer transistors enables efficient transfer of charge from the photodiodes, reducing noise and improving image quality.
