IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240214703 titled 'IMAGE SENSOR
The image sensor described in the patent application consists of multiple pixels, each containing two photodiodes, transfer transistors, reset transistors, a switch transistor, and a driving transistor.
- Each pixel has a first and second photodiode for capturing light.
- The first and second transfer transistors are connected to floating diffusion nodes to transfer charge.
- Reset transistors are used to reset the floating diffusion nodes with specific power supply voltages.
- A switch transistor connects the second floating diffusion node to the first floating diffusion node.
- A driving transistor outputs an output voltage based on the voltage of the first floating diffusion node.
Potential Applications: - Digital cameras - Smartphone cameras - Surveillance cameras - Medical imaging devices
Problems Solved: - Improved image quality - Enhanced low-light performance - Reduced noise in captured images
Benefits: - Higher resolution images - Better overall image quality - Improved performance in various lighting conditions
Commercial Applications: Title: "Advanced Image Sensor Technology for Enhanced Photography" This technology can be utilized in the development of high-quality digital cameras for professional photographers, smartphone manufacturers looking to enhance their camera capabilities, and companies producing surveillance systems for improved security monitoring.
